Release notes for Platinum DCMs


Platinum is Guralp Systems’ next-generation firmware for CMG-EAMs, CMG-NAMs and CMG-DCMs.

Finding the currently installed version

On versions released during or after 2012, open the System status page (the front page of the web interface) and click the Linux system tab.

On earlier versions, or on the command line, run the command:

cat /etc/build.version

Upgrade instructions

  • To reflash old CMG-DCM firmware to Platinum, please see this page.
  • Platinum system currently running firmware before build 10000, please refer to the instructions in MAN-EAM-0001 (PDF or HTML) and see the important notices below.
  • To upgrade a Platinum system currently running firmware after build 10000, please refer to the instructions in MAN-EAM-0003 (PDF or HTML).

Important notices

Please run the upgrade procedure twice.

You may see several errors about Directory not empty and references to broken files. These are normal and the second upgrade run is careful to leave the system in a consistent state. If you get the error message /usr/bin/upgrade: Command not found then run hash -r before running upgrade again.

Change log

This release provides the following change:
  • The CD1.1 multiplexor/frame database, data-mux-cd11, release 2.0.1
    • Fix an internal consistency check that was misfiring, occasionally causing frames of a certain specific size to be dropped with a message in the log "Source client sent unreasonable frame size (x). Disconnecting it." (with an unreasonable value for x).
2014-09-26 : release CMG-DCM-mk2x_stable-10934-DCM+497
This release provides the following changes:
  • The GNU "Bourne-Again" Shell, bash, release 3.2
    • Patches for CVE-2014-6271 and CVE-2014-7169 ("shellshock"). Please note that our system() shell is actually busybox and not bash.
  • General:
    • Leap-second table filename made consistent.
  • Code to implement IIR filters, libiir, release 1.1.1
    • Updated to upstream version.
    • Improve ability to query filter coefficients.
    • Add C++ wrapper library.
    • Fix problem with initialisation of integrating filters (those which are not stable at DC).
2014-08-14 : release CMG-DCM-mk2x_stable-10934-DCM+493

This release provides the changes listed below. Note that there were some programs which were recompiled to keep the same version as the other platforms but which weren't actually changed in any way on the CMG-DCM-mk2x.

Major changes:

  • gdi-link now disables terminal access by default, to prevent unauthorised DM24 configuration or firmware changes. Sensor controls can be enabled or disabled separately and are enabled by default, hopefully limiting the number of affected deployments.

Detailed changes:

  • Code to link two (possibly remote) GDI multiplexors, with backfill, gdi-link, release 1.2.0
    • *IMPORTANT CHANGE TO DEFAULTS*: remote DM24 FORTH terminal access is now disabled by default. It can be re-enabled on the system that is running the transmitter, gdi-link-tx.
  • Common miniseed output code, libminiseed-out, release 1.2.0
    • Fixes for time-window retrieval mode. A cleaner, faster implementation of this function should resolve issues with client timeouts when requesting data by time window.
  • The miniseed record generator for Platinum/GDI, gdi2miniseed, release 1.2.4
    • Updated to work with libminiseed-out release 1.2.0
  • The SEEDlink server, seedlink-out, release 1.2.0
    • Fix some minor issues (such as status messages, or the results of a request that matches no records) relating to FIFO and time window requests.
    • Improve the implementation of time window retrieval to start returning records much more quickly than before, thus avoiding client timeouts.
  • Platinum basic system files, Pt-baselayout, release 2.3.27
    • Automatically recreate serial port configuration subdirectories if they have been manually deleted by the user.
    • Fix multi-user permissions issues with serial ports.
  • Configuration scripts and templates, config-scripts, release 2.1.37
    • TCP to serial converter: fix saving of the IP address filter.
    • GCF over serial port receiver: fix disabling of BRP.
    • gdi-link: add some help, don't double-hide the advanced section, and add support to the transmitter for whether sensor control and/or DM24 FORTH terminal access are enabled (the options are independent).
  • Simple network configuration scripts, console-config, release 1.2.0
    • Add some new, simpler command-line tools for manipulating configuration files. These will mainly be used by internal programs, but can also be useful for scripting automatic changes and for support queries.
  • Code to record raw data from attached device on serial port, serial-recorder, release 1.1.0
    • Always close down and start a new file on an hour boundary; Don't rely on this process being triggered by more data arriving. This is better for systems configured to capture occasional output.
  • A CGI program allowing control of various Platinum functions through XMLRPC, xmlrpc-control, release 1.0.3
    • Fix command for flushing to disk.
  • The TCP to serial convertor daemon, tcpserial, release 1.0.3
    • Fix IP address filtering configuration.

2014-08-04 : release CMG-DCM-mk2x_stable-10934-DCM+470
This release provides the following change:
  • The CD1.1 sender, data-out-cd11, release 3.0.1
    • Fix order of "action,channel" when loading channel filter configuration.
2014-06-23 : release CMG-DCM-mk2x_stable-10934-DCM+469
This release provides the following changes:
  • A framework for simple status reporting, quickstatus, release 1.0.3
    • Move cleanup of quickstatus data on process exit into the library.
  • Configuration and status monitoring for NTP, ntp-wrapper, release 3.0.2
    • Properly drop root after performing a privileged operation.
  • The configuration interface, config-base, release 2.0.13
    • Improve CGI error reporting.

    • Don't reject a dash in gdi-link-rx peer names.
  • Serial port diagnostics utility, rs232-detect, release 1.0.1
    • Test for 7200 baud, as this is a known side effect of a bug elsewhere.
  • Common utility code, libgslutil, release 1.2.4
    • Add a utility function.
2014-06-17 : release CMG-DCM-mk2x_stable-10934-DCM+461
This release provides the following changes:
  • Common functionality for CD1.1 modules, libdata-cd11, release 2.0.0
    • New frame splitting/building code to allow a common implementation of consistency tests across all modules.
    • Removed mux IPC code as it is no longer common between different modules.
    • Generally improve error checking and handling, and provide more common, consistent utility functions for parsing data.
  • The CD1.1 sender, data-out-cd11, release 3.0.0
    • A new IPC mechanism has been implemented to allow for more robust data servoing. Now when there are multiple senders to different destinations they cannot interfere with each other or with receivers, and yet they are able to cope with vastly different link speeds and fault conditions.
  • The CD1.1 multiplexor/frame database, data-mux-cd11, release 2.0.0
    • This release implements a new IPC mechanism which allows servoing of data rates independently for different modules. Receivers can now receive as fast as we can synchronise data to disk; senders now have notifications (fast) and data transfer (slow) decoupled. This allows all modules to be as independent as possible yet ensures data is never lost, even when inbound data rates are potentially much faster than outbound.
    • This release also implements "generation counters", which are simply a more explicit way of ensuring that a relay station does not transmit duplicate old data when one (or more) array element is backfilling.
  • The pass-through CD1.1 receiver, data-in-cd11, release 2.0.0
    • Improve validation of inbound frames, to ensure we don't accept data on the TCP link that is later rejected by other parts of the system.
    • Implement a new IPC mechanism that allows the receiver to servo to the highest speed possible, ensuring that data is written to disk before it is acknowledged to the sender.
  • The CD1.1 subframe generator for Platinum/GDI, gdi2cd11, release 1.4.0
    • Update to match new IPC scheme used by other modules. This is a much smaller change for this module, as the new semantics exactly match the way it was expected to work previously.
  • The Quick Seismic Characteristic Data transmitter, qscd-out, release 1.3.1
    • Add XML status output to QSCD sender
  • Support programs for DM24/CD24 (BRP mode), dm24-support, release 1.1.18
    • Update bundled firmware versions: CD24 to v.322 and DM24mk3 to 106b57s.
2014-04-14 : release CMG-DCM-mk2x_stable-10934-DCM+457
This release provides the following changes:
  • The secure sockets layer library, OpenSSL, release 1.0.1g
    • Fix for the heartbleed vulnerability.
    • The private key and self-signed certificate that each machine generates for its webserver will be regenerated automatically after this upgrade.
  • Platinum basic system files, Pt-baselayout, release 2.3.23
    • Fix for services displaying as "restarting" on long-running systems.
    • Fix for systems configured to 10BASE-T with no duplex setting: these are now considered to be half duplex.
    • Regenerate the SSL key used by the webserver, in case the old key material was leaked due to the openssl heartbleed vulnerability. A new key and self-signed certificate will be generated on each machine.
    • Ignore remote NTP queries to avoid amplification attacks.
2014-02-12 : release CMG-DCM-mk2x_stable-10934-DCM+435

    This release updates OpenSSH to version 6.0p1 and includes multiple changes.
    • Platinum basic system files, Pt-baselayout, release 2.3.4
      • Significantly reduce the window during an upgrade where the filesystem is inconsistent. Now there should only be a few seconds (after rsync has finished deleting old files but before the post-upgrade scripts run) where losing power would cause a problem.
      • Fix bug where services would show as “restarting” if the system clock went backwards (e.g. after an NTP update).
      • Fix bug where a service could mistakenly be considered to have stopped, and a second copy was started.
      • Fix bugs with starting/stopping NTP and ntpstatus.
      • Squelch error message “"" is not true/false.” on upgrade.
      • Move NTP configuration file to /etc/ntp.conf.local in line with all other configuration files.

      • Minor improvements to file name entry.
      • Minor improvements to directory-cleaner page.
    • Configuration and status monitoring for NTP, ntp-wrapper, release 2.0.0
      • A rewritten NTP scanning subsystem which is much more sensitive to changes in NTP lock status. Now it will report that NTP is unlocked in some situations where is used to report a large difference instead.
      • Exposes some additional information about the clock source (NTP peer or GSL digitiser) via XML status.
      • Introduces a grace period of 30 minutes at system start where it will allow NTP time to lock on and synchronise the clock before highlighting an error state in XML status.
      • Also exposes the lock status in a machine-readable fashion for other programs on the system to use, so they are consistent with the status as reported by the scanner.
    • Code to output NMEA and PPS based on NTP status, ntp-to-nmea, release 1.2.0
      • Use new NTP status flags from the new NTP scanning subsystem.

    2012-01-07 : release 10934
    This release updates the leap second table to include the recently announced June 30th, 2012 leap second. Leap seconds cannot be computed in advance so it is necessary to signal the declaration of new leap seconds to running applications. Platinum includes a leap second table which lists all known leap seconds; this table has to be updated when a new leap second is declared.There are two ways that a customer can get the updated table. Platinum systems with a permanent internet connection will check every week for updates to the table and will automatically download any that they find. The check occurs at 02:17 UTC each Saturday morning and the HTTP protocol is used to download the updates. Platinum systems without a permanent internet connection will acquire the updated table when their firmware is updated; this is the first firmware release where the leap second table includes the 2012 leap second.It is possible to tell whether the table has been successfully updated by running the command:
    ls -l /usr/share/libiso8601/leap-seconds
    The output will look like this:
    -rw-r--r-- 1 root root 108 Feb 26 2011 /usr/share/libiso8601/leap-seconds

    The size of the file is given in the 5th field of the output. If the size is 108 bytes (as in the example), it is the old (pre-2012-06-30) version. If it is 112 bytes, it is the new version.

    2011-12-11 : release 10931
    This release adds support for the new, rack-mounted EAM-R and the rack-mounted CD24R8. Changes have been made to:
    • Pt-baselayout:
      • Support added for the EAM-R
      • Minor bug fixes: disk flush buttons and storage daemon permissions
    • xmlstatus-assert:
      • Fixed parsing of “enabled” value in configuration file
    • The I2C support library, ioline-gsli2c:
      • Added a drive for the PCA9593 I/O expander
    • The GCF BRP receiver, gcf-in-brp:
      • This now correctly identifies disconnected devices.
    • A new tool-kit for supporting the use of USB-to-serial converters, usbserial-support:
      • A script, add-USB-serial.sh, allows a permanent USB-to-serial cable installation.
      • A new program, tty_map_tool, aids mapping of physical ports to USB serial numbers for multi-port CMG-NAMs.
      • A new program, run-cd24r8, automatically detects and runs CD24R8 digitisers with a USB-to-serial converter.
    2011-12-01 : release 10896
    This release contains a single bug-fix for the BRP receiver, gcf-in-brp:
    • The “bytes received” counter now resets to zero when no data is being received
    2011-11-30 : release 10891
    This release contains some minor improvements and bug-fixes:
    • The GCF input library, lib-gcf-in
      • Some additional guards again invalid or unexpected input have been added.
    • The GCF compressor, gdi2gcf
      • A fix has been applied which prevents a potential crash when dealing with status blocks over 1000 bytes in length.
      • A fix has been applied which correctly encodes CD24 digitiser types in the GCF block header.
    2011-11-16 : release 10879
    This release fixes a potential crash in gdi-link-rx when new clients are in the process of connecting. This seems to only have occurred on the CMG-NAM-mk2.
      2011-11-16 : release 10874
      This release contains a fix for a race condition, observed on the CMG-NAM-mk2, where sometimes, at bootup, a service would only listen on either IPv4 or IPv6 addresses, but not both. This occurred because the service was started before any address was configured on the physical network interface, and the support library’s behaviour was to check for configured addresses before activating results for an address family. This check has now been removed.
        2011-11-1 : release 10869
        This release contains a number of major new features.
        • new hardware platform: CMG-NAM-mk2
        • a new, improved storage and recording subsystem
          • full and consistent NFS and ext4 support across all platforms (DCM can’t format ext4 natively though as e2fsprogs doesn’t fit)
          • much improved user feedback, esp. wrt errors
          • improved performance
          • correctly merges, sorts and removes duplicate records in GCF/miniSEED

                hardware, would sometimes cause the disk not to be powered up when
                required. This is fixed.
              2011-07-29 : release 10473
              • Bug-fix: gdi-record was over-zealous about error handling. Some obviously non-recoverable errors

              2011-07-28 : release 10469
                This release contains a large number of improvements, as detailed below:

              • GCF serial receiver: gcf-in-brp
                • Feature: an instrument that stops transmitting data is now highlighted in the status display.
                • Feature: terminal events are now logged to /var/log/messages.
                • Bug-fix: Stream IDs which, when encoded, contained a certain character could cause an
                  unwanted terminal session to be started. This is now detected and avoided.
              • Internal message handling: libmsgbus
                • Enhancement: improved output buffer for queued messages
                • Bug-fix: when writing data faster than they could be consumed,
                  there was potential for corruption; This is now fixed.
              • CD1.1 multiplexor: data-mux-cd11
                • Enhancement: provide a flow control mechanism to inhibit enthusiatic data sources.
                • Enhancement: improved behaviour of CD1.1 relay streams with high in-bound data
                  floes and low output bandwidth.
              • CD1.1 receiver: data-in-cd11
                • Enhancement: subframe presence tracking support.
                • Enhancement: a flow control mechanism to prevent overloading the multiplexor.
                • Enhancement: simplified ACK/NACK processing.
              • GDI to CD1.1 convertor: gdi2cd11
                • Updated the handle the new libdata-cd11 source client API.
              • CD1.1 transmitter: gcf-in-brp
                • Feature: Simplified outbound ACK/NACK frames.
                • Enhancement: Improved diagnostic logging for situations that cause a module restart.
                • Bug-fix: Simplified and corrected generation of outbound ACK/NACK frames (which
                  indicate to a receiver which frames we still have available).
                • Enhancement: Further improvements to ACK/NACK handling: Processing of incoming frames is no
                  longer deferred, even if backfill is in progress, and an extra field
                  to keep track of which frames have been sent in the current TCP
                  session was added to avoid duplicates.
              • CD1.1 library functions: libdata-cd11
                • Feature: subframe presence tracking. This is useful for seeing how
                  subframes propagate through the software modules, and is more generally
                  applicable as a way to look for data gaps.
                • Enhancement: a feedback path between the multiplexor and source clients may
                  optionally be employed. This helps data-in-cd11 to extend the feedback path
                  back over the TCP link to the sender.
                • Bug-fix: Corrected corrupt channel names in CD1.1 subframe presence tracking.
                • Enhancement: Added a mechanism to improve data flow behaviour when under very high load.
              • CD1.1 utility functions: data-cd11-misc
                • Feature: Added a subframe presence viewer.
                • Enhancement: Improved much of the CD1.1-related HTML code.
              • GDI link protocol: gdi-link
                • Bug-fix: Scream client terminal passthrough.
                • Enhancement: Added a more consistent scheme for recording port names, remote hostnames.
                  In particular the remote host/port are now displayed correctly in the
                  web menu for instrument control.
                • Enhancement: This is the first release which uses/fully supports negotiating optional features
                  on the link.
              • GCF scream tranmsmitter: gcf-out-scream
                • Enhancement: Remote site relaying port/terminal naming updates.
                • Enhancement: Meaningful port names are now switched on by default (requires Scream 4.5 for terminal).
              • GCF scream receiver: gcf-in-scream
                • Enhancement: Tidied up DM24 terminal naming.
              • MiniSEED compressor: gdi2miniseed
                • Enhancement: Added improvements to the “Extract miniseed records” tool, including support for
                  non-512-byte record sizes.
              • MiniSEED tranmsmitter: libminiseed-out
                • Enhancement: made changes to support the “Extract miniseed records” tool.
              • Platinum: Pt-baselayout
                • Bug-fix: corrected an issue with “upgrade –force-factory-settings” on recent EAMs.
                • Feature: added support for KVH DSP1500 digital gyro serial port option.
                • Enhancement: added supporting functions for better removable disk hardware interaction
                  on EAMs.
                • Bug-fix: Fixed a bug where “crontab -e” complained about missing editor.
              • Configuration scripts: config-scripts
                • Feature: added support for configuration of KVH DSP1500 digital gyro.

              • CD24 low latency support: cd24-lowlatency-in
                • Bug-fix: stepping of RTC to match data when difference > 4 hours.
              • DM24 digitiser interface: dm24-support
                • Bug-fix: we are now more conservative about printing “insufficient baud rate” warnings.
                • Enhancement: added improvements for naming of remote instruments connected via gcf-in-scream or gdi-link-rx.
                • Enhancements: various changes to the configuration CGI:
                  • support new GLONASS+GPS receivers.
                  • updates for changes to DM24mk3 compression, STA/LTA and strong motion command implementation.
                  • support for low latency auxiliary (mux) channels and different sample rates (DM24mk3 only).

                • Enhancement: Improved logging and status output which should make it much clearer when failures have occurred and why. XML status should now be much better at highlighting any failure.
                • Bug-fix: Fixed a bug where, under certain circumstances, a failed flush was not retried later.
              • Storage device handling: rdisk

              2011-06-03 : release 10302
              • Bug-fix: Commands such as minicom PortA now don’t print an error message on start-up (the previous fix didn’t correctly cover all circumstances).
              2011-06-01 : release 10286
              • Bug-fix: gdi-record should no longer create empty “dircopy” directories on the disk

              • One or two terminology changes concerning sensors/instruments
              2011-05-27 : release 10254
              • Minor cosmetic changes only.
              2011-05-26 : release 10250
                This release provides a new sensor control framework, designed to ease the implementation of many current and future sensor control facilities. The main user-visible changes are listed below:

              • New menu category: “Control → Sensors”.
              • Menu “Configuration → System” changed to “Configuration → Sensors”.
              • A new, prototype sensor control screen.
              • A new (but currently non-functional) menu item: “Tools → Sensors → FORTH terminal access”.
              2011-05-25 : release 10246
              • Bug-fix: The cd24-lowlatency-in service now ensures that mass position commands and offset-null commands work by forcing the CD24 sensor-type to 3.
              2011-05-24 : release 10183
              • Bug-fix: The XHTML MIME-type list now supports the preview of the digital compass subsystem.
              • Bug-fix: Configuring specific media-types for the Ethernet interface now works correctly. If you have been affected by this bug, you should perform the upgrade, then run the command
                rm /etc/init.local/net_eth0

                and then reboot the system.

              2011-05-23 : release 10179
              • Feature: The gcf-out-brp service now uses the XML Status infrastructure.
              • Feature: A new option now allows you to record system log files to disk.
              • Feature: A new tool, cd24fw, allows upgrading of firmware on attached CMG-CD24 digitisers.
              • Feature: This release contains a preview of a new digital compass / orientation sensor subsystem. There is no configuration or recording of time-series data yet. Note: this feature is not supported on legacy CMG-DCM platforms.
              • Bug-fix: The dircopy feature no longer creates empty directories on removable storage devices.
              • Bug-fix: The --restore-defaults option to the upgrade tool now works correctly on CMG-EAMs.
              • Bug-fix: The syslog subsystem can now be restarted properly.
              • Bug-fix: EAM serial ports now stay powered up when a program is accessing them. This might lead to increased power consumption if ports are configured but not in use, but decreased power consumption if ports have been configured to None and were previously powered up. This resolves issues where DM24s had undetected framing errors during terminal access and where CD24s went to sleep if a terminal was left open.
              2011-05-11 : release 10117
              • A new feature can raise an external hardware alert if monitored status parameters drop below configurable thresholds.
              • Fixes a bug which would trigger undesirable behaviour in some subsystems if an EAM booted with an invalid date (pre-1970) in the real-time clock. The date is now forced to 1/1/1970 under these circumstances.
              2011-05-11 : release 10083
              • Fixes a bug in the “linux system” status display which incorrectly reported the statistics (size, free-space etc) of root partitions larger than 2GiB.
              2011-04-26 : release 10071
              • Fixes a display issue under IE where IE would not correctly split up config pages into their sections.
              • Adds u3-tool (EAM, NAM and NAM64 only) for repairing Sandisk Cruzers which have the U3 firmware “feature” where Win32 has inadvertantly activated it and destroyed the data.
              2011-04-26 : release 10064
              • Fixes some issues with the SeedLINK XML info packet creator. Tested with IRIS slinktool and slinktool from seiscomp-2.6 and seiscomp-3.0.
              2011-04-20 : release 10060
              • Fixes a bug which marked a newly-changed password as expired when the date is 1st Jan, 1970 (which will be the case for a freshly booted CMG-DCM with no GPS fix).
              2011-04-18 : release 10056
                This release contains fixes for bugs in subsystems that have not yet been formally released:

              • cd24-lowlatency-in: fixed a “midnight rollover” bug, which was due to the integral discontinuity of GCF date/time at midnight;
              • cd24-lowlatency-in: fixed a bug where the service wouldn’t start unless a TCP copy service name had been configured (this is now optional);
              • libiir: version bump; upstream version has improved initial conditions for IIR filters based on analysis of filter (fixes numerical instability in computation of IJMA for gdi-eventproc-ijma)
              2011-04-08 : release 10048
              • New feature: XML status assert daemon. A GPIO line can now be asserted when a system SoH parameter value falls below a configured threshold.
              • New feature: Support for low-latency mode of CMG-CD24 digitisers. The CMG-CD24 digitiser has been provided with a new, low-latency mode which required an special, low-latency protocol in order to transmit data without the delays associated with the packetisation of GCF. The EAM can now receive data from the CMG-CD24 using this protocol.
              • Fixed a bug where the configuration page for the GSTM server could occasionally be only partially displayed in the web interface.
              2011-03-31 : release 10008
              • Fixed a bug where formatting a disk would lead to only 2.0Gbyte being available. Simply upgrade and reformat any affected disk, or format the disk on another machine. Also applies to USB sticks (internal or external).
              • GCF TTL and DM type fields are now a hidden field in XML status.
              2011-03-22 : release 10000
              • Compiler update for EAM. GSL have upgraded the C compiler and system libraries used on the EAM. This results in almost every file needing to be replaced. Because this process is sensitive to being interrupted partway through, we recommend it is not carried out on deployed units, and instead is only carried out when units are brought in for servicing or when a backup unit can be deployed immediately.Details of the upgrade procedure can be found here.
              • New feature: multi-user support. The next version of Platinum brings a major change: support for multiple users. Each user has a distinct password and level of access. A user with only basic access may only be able to view the status of various parts of the system, whereas an advanced user may be given rights to control or configure certain components. New user IDs can be created and modified through the configuration system where their access levels can also be set. For users familiar with Linux, this is implemented using true Unix users and groups, so it also brings system-wide security. Please note this feature required fundamental changes to various parts of the Platinum operating system and there may still be situations where a user cannot accomplish something they should have been able to: please contact This email address is being protected from spambots. You need JavaScript enabled to view it. in such cases for a speedy resolution.
              • New feature: XML status subsystem. An advanced state-of-health reporting system has been added to this release of Platinum. A newly-designed front page now shows the status of the GPS, hard disk, sensors and virtually every software component on the system in a simple grid arrangement, which will instantly highlight any problems on the unit. Viewing this status does not require authentication, which removes a step from the process of checking system operation. This information can also be retrieved as an XML file (perhaps using the XMLRPC interface) for machine processing. ISTI have developed a forthcoming iPhone/iPad app for viewing this status, and Seisnetwatch integration is planned.
              • Units with optional extra flash modules now have information about the flash module on the front page. All units programmed since April 2011 will now have a marker in their EEPROM if a flash module was present on the original sales order, which will allow instant identification of units where the flash is malfunctioning or not fitted.
              • Some XMLRPC controls have been added for automation. At present XML status can be retrieved and sensor control (mass lock, unlock etc.) is supported, as well as initiating a flush to disk. Much more will be added in future. Contact Guralp support for more information.
              • When using an EAM to transmit GCF data through a serial port, it is now possible to use Scream to configure any DM24 instrument connected to the EAM. This has always been possible when using the network protocol, but has not been possible until now when using the serial protocol (BRP).This feature does have the limitation that data is not buffered while the instrument terminal is open.Please note that when using an EAM, Guralp Systems recommends the use of IP networking over serial data transmission if at all possible. This can be achieved over a serial line connection using PPP; please contact support for details. The web interface also allows control and configuration of attached DM24 and CD24 digitisers.
              • A new, more robust mechanism of controlling sensors (lock, unlock, centre and calibrate) has been added. This has been extensively tested with the DM24mk2.
              • A new sensor control page has been added which attempts to determine from the DM24/CD24 which options it should display. There is an autodetect feature and a manual override.
              • Results of long sensor commands (e.g. DEPLOY) now automatically scroll.
              • The last few terminal sessions to DM24 are logged for debugging failures; use the dump-serial-log program on files in /var/log/libterminal to view the logs (or send those files to This email address is being protected from spambots. You need JavaScript enabled to view it. ).
              • Improvements to the web interface presentation and usability have been made in several areas (especially the configuration pages).
              • A traditional cron daemon (vixie-cron) has been added.
              • Outbound email configuration now works correctly. Remember to run newaliases if you update the alias file by hand.
              • The gcf-out-scream Scream server now tries very hard to keep the same COMxx number for Scream4.4/Windows compatibility. COMxx numbers should no longer change whenever the Scream server is restarted.
              • Compression of SOH information from DM24mk3s was improved, should lead to less noise (and less bandwidth) in the gdi-link/gsms-out protocols.
              • data-mux-cd11: a bug where deferred data (e.g. from a faulty DM24mk3) was not transmitted on to the sender under certain circumstances was resolved
              • Fixed a bug where the friendly service name of gdi-base was not used while configuring gdi2gcf with a channel map.
              • Fixed a bug in the WIN sender configuration script’s UDP mode (it was not allowing the form to be submitted).
              • Temperature sensors should be more reliable. However a large number of units were shipped without the temperature sensor chip.
              • Fixed a bug where overvoltage settings in ioline were not saved.
              • Resolved a longstanding bug where NTP status would stop being updated after some weeks, with Malformed or unexpected reply messages in the system log.
              • serial-recorder now copes with recording from a GPS unit (control lines were previously confusing it).
              • Upgrade now always correctly reports old and new release numbers.
              • The upgrade option on the web page no longer reports success on failure.
              • New Unix apps: base64, iostat, last, pmap, traceroute6, who, xz.
              • Platinum code now copes with previously-unknown non-time-series blocks from the DM24mk3, such as TS (trigger summary), which are passed through verbatim.
              • Fixed a bug where the digitiser configuration page would say “Load complete” even if loading failed.
              • Bugfix in the configuration pages when deleting a table row with a checkbox.
              • VLAN configuration is improved and previously-configured VLANs can now be deleted through the web interface.
              • Significant improvements to starting, stopping and restarting services have been made.
              • GSMS sender will now cope with dynamic notification of leap seconds..
              • Configuration of 230400 baud on DM24mk3 units that support it is now available through the web interface
              • Improved behaviour of the system when a service failed to start correctly. This should improve the behaviour of the service control commands as well as reducing the scope for getting the system into a state where it does not boot.
              • Improved the wording of the NTP configuration page.
              2010-11-08 : release 3796
              • Fixed an “off-by-one” in data-in-cd11, so now this code is consistent with the code in data-out-cd11, the AFTAC receiver and the standard (but not the CTBTO software);
              • The CD1.1 subsystems now use extra information in the heartbeat frames from the sender to mark any unavailable frames as unavailable in the receiver, to stop the receiver gap list from building indefinitely (e.g. in the face of a bug like the above).
              • Some TCP changes have been made which may help with an intermittant problem where the BRP sender could lock up.
              2010-09-06 : release 3772
              • This release corrects a second problem with the CD1.1 sender channel filtering.
              2010-08-25 : release 3768
              • This release fixes a bug in the data-out-cd11 configuration which affected the channel filtering.
              2010-08-23 : release 3764
              • This release fixes a problem with the data-terminal command’s menu-driven mode, which was broken in the last release; It would always say “No terminal selected”.
              • New versions of the terminal command functions have been introduced in order to support the DEPLOY command on the latest OBS systems. Command usage and results should not change.
              2010-08-20 : release 3756
              • This release adds support for conventional /etc/rc.local and /etc/rc.local.d processing.
              2010-08-20 : release 3751
              • This release contains a single change to the OBS section of the instrument control page. The time-out associated with the DEPLOY command has been increased to 25 minutes.
              2010-08-13 : release 3748
              • This release contains a single change to the CD1.1 sender which fixes interoperability issues for a specific customer.
              2010-08-09 : release 3744
              • Added an option to allow a GCF input process to set the system clock whenever it sees a 00 status block from an attached DM24. This option is enabled by Configuration → Serial → Port? → GCF input → Advanced → GCF timing. It is off by default, as it is only intended for coarse timing with a Mark 2 DM24. DM24mk3 and CD24 digitisers produce more accurate timing information, embedded in the RTStatus packets.
              2010-07-21 : release 3719
              • The time-out value of the OBS DEPLOY command has been increased because a new CMG-DM24 firmware build requires the terminal to be kept open for longer.
              2010-07-19 : release 3699
              • Further improvements to the support for LCDs on CMG-EAMs.
              2010-07-16 : release 3696
              • Adds preliminary support for external Liquid Crystal Displays (CMG-EAMs only).
              • Adds DM24 state-of-health information to LCD displays, including those on CMG-5TDs. If Unified Status blocks are enabled, real-time GPS, clock and data-quality flag information is displayed; if not, the DM24 status blocks are displayed verbatim.
              • The RTD sender, implemented for a specific customer, has been removed from the distributed firmware as that customer no longer has a requirement for it.
              • Additional improvements have been made to the upgrade script to correctly handle symlink problems when upgrading CMG-DCMs. Note: DCM users should install this upgrade twice, once to install the new upgrade script and once to execute it.
              2010-07-15 : release 3670
              • A new upgrade script handles a problem involving undeletable symlinks when upgrading CMG-DCMs. Note: This upgrade should be installed twice: once to install the new upgrade script and once to execute it, although this is only necessary on CMG-DCMs.
              • Fixes a problem that could cause incorrectly displayed dates in the back-fill database of the CD1.1 sender.
              • Various other CD1.1 resilience improvements.
              2010-07-12 : release 3641
              • Fixes a problem affecting interoperation with one particular CD1.1 receiver.
              2010-06-25 : release 3628
              • Fixes a problem that could stop CD1.1 calibration values from being applied.
              2010-06-23 : release 3624
              • GCF handling improvements:
                • All GCF packets with zero sample-rates (other than *01 and *SM) are now treated as text and passed through accordingly. Previously, unrecognised zero sample-rate packets were rejected. This supports the newly added *TS streams and provides future-proofing for any other new text streams.
                • The digitiser type, FIR filter tap-table look-up and variable gain settings are now passed as meta-data to GDI. The GCF compressor, gdi2gcf has been modified to read these data from GDI and reconstitute them in out-going GCF packets.
                • GCF now correctly handles the situation where a segment end requires three GCF blocks to be generated (one at 8-bit, one at 16-bit, and one at 32-bit compression).
              • CD1.1 sender changes: A non-standard receiver was encountered that required more laxity in validity checking and a longer connection time-out. Configurable options to handle this situation have been provided: these can be enabled and adjusted from the “expert mode” screen of the CD1.1 sender configuration dialogue.
              2010-06-22 : release 3559
              • The CD1.1 transmitter, data-out-cd11, now has a configurable transmit queue size. This used to be fixed at 128k but the new default is 512k. This has improved performance when backfilling an array over a VSAT link.
              • The time-and-date library, libiso8601, now correctly handles invalid times in the system clock, preventing some display and logfile corruption on DCMs between booting and first synchronising.
              2010-06-07 : release 3551
              • Added a script to set ad-hoc mode on a wireless network adapter and configure the associated link layer. Designed for use with specific customer software only and not intended for operational use. For more details, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. .
              2010-05-27 : release 3547
              • This release contains the latest DM24Mk3 firmware image (in the /usr/share/firmware/CMG-DM24mk3 directory). There are no changes to the Platinum firmware itself.
              2010-05-26 : release 3543
              • The seedlink server (seedlink-out) is now tolerant of arbitrary whitespace in received command strings. This allows interoperability with Anthony Lomax’s SeisGram2K software.
              • The configuration screen for the RTD server (rtd-out) produced an inappropriate error message when no sender had previously been configured. This has been fixed.
              2010-05-21 : release 3535
              • Added support for the USGS RTD protocol over IP or serial links.
              • Added a serial port recorder: Any serial port can now be configured to record to a file all data received over the port. Individual lines in the file are time-stamped.
              • Improved accuracy of voltage monitoring.
              • All digitiser configuration changes now cause a re-boot of the digitiser module so that the changes take effect immediately.
              • The DHCP client now behaves better when operating in a relayed network.
              • Fixed a bug in the Spyrus support whereby generating a new keypair in an unused slot changed the active slot.
              • Fixed a few bugs in the digitiser configuration page related to tap settings, triggering settings and short IDs. Added checks for invalid configurations which could cause the digitiser module to continuously reboot.
              2010-05-11 : release 3488
              • Improves debug logging and fixes a bug in the CD1.1 sender which affected systems with multiple senders: one sender reconnecting could halt the other.
              2010-05-10 : release 3480
              • Fixes a bug in the CD1.1 sender whereby if the first reconnect attempt after a valid connection ended failed, the reconnect timer was not rearmed. This is now resolved.
              2010-04-30 : release 3476
              • The pppd-watchdog service’s process termination and reboot triggering are now switcheable separately (for applications using this service to monitor things other than pppd).
              2010-04-29 : release 3455
              • Added cURL and libcurl. The cURL program performs file-transfers using a wide variety of protocols, including HTTP, FTP, SFTP, TFTP and more. The libcurl library provides the same facilities for platinum modules.
              • Some CD1.1 updates announced for release 3420 were not actually included in that release: this release remedies that.
              2010-04-27 : release 3420
              • CD1.1 “aux status” information is now 8-bit rather than 10-bit, and can now be displayed in the multiplexor subframe viewer.
              • CD1.1 sender no longer resolves IPv6 addresses (the protocol is strictly IPv4 at present).
              • The CD1.1 multiplexor subframe viewer now highlights fields that have caused attention bits to be set (e.g. GPS, timing).
              • Improved Spyrus behaviour when re-initialising the card while it is in use (and various Spyrus tidy-ups).
              • We no longer associate to unsecured wireless access points when we already have an access point configured, just not available
              • Authentication key ID in outgoing CD1.1 data frames now changes as expected when cd11-management-tool is used to change it at runtime.
              2010-04-1 : release 3360
              • Changed behaviour of wireless networking: The system will not now automaticall bind to an insecure network when no recognised networks are available.
              2010-03-31 : release 3314
              • Improved DHCP client: dhcpcd-5.2.1 brings many robustness improvements. This fixes the longstanding issue where booting a DCM/EAM without the network cable plugged in would lead to never getting a DHCP assigned address. It also adds resolv.conf and default route metric support for better behaviour on units with wired and wireless networks active simultaneously.
              • Change gdi-link-tx to using hourly files for backfill: A minor tweak, this allows the size of the backfill directories used by gdi-link-tx to be controlled in a more fine-grained manner, allowing the use of gdi-link-tx backfill on units with smaller amounts of flash (e.g. DCMs).
              • Robustness and configuration improvements for GSTM server: GSTM server now uses a flat configuration file rather than XML, making it much easier to manipulate by script (or by hand). Along with this, additional logging, debugging and watchdog features have been added.
              2010-03-24 : release 3271
              • rdisk and gdi-record now support flushing to disk from an external button (e.g. on CMG-3EX with integrated EAM)
              • Improved status reporting from rdisk (it now reports flush failures and also reports status information to an attached LCD).
              • Basic SoH information is now transmitted in MiniSEED headers.
              • Improved implementation of INFO command in the SEEDlink server.
              • Bug fix: calibration commands with frequencies expressed in seconds now work reliably. An error which ocurred when a calibration command was issued while a calibration was already in progress has been fixed.
              • Fixed a problem which could cause display corruption when veiwing GCF logs.
              2010-02-15 : release 3170
              • 3170 is the first release with EAM LCD support, in anticipation of LCDs being fitted to EAMs. The NAM/NAM64 LCD support has been rewritten to use the same framework developed for EAMs.
              • Python 2.5.1 has been removed from the NAM/NAM64 build as it is no longer required by current modules. Python 3 could be provided if requested.
              2010-02-08 : release 3143
              • Recording to disk: the configuration page now allows the user to choose a destination when there are multiple options (e.g. “record to internal USB disk in tray” or “record to external USB device”).
              • Improvements to seedlink XML info output.
              2010-01-10 : release 3063
              • Fix for setting up gcf-out-brp (GCF out) on a serial port for the first time under recent Platinum (would complain about missing “gcfout_dbdir” or “brp_dbdir” config entries in the log).
              • Initial modem dial-in support (mgetty).
              • Improved DM24 terminal support.
              • Support for newer DM24mk3 bootloader and firmware, including (infoblock retrieval).
              • Improved envirolog graph plotting CGI.
              • Fix for pushing to network broadcast address in Scream server.
              • Improved extract_miniseed and seedlink. New features added. Many of the seedlink INFO commands should work now, as should time window extraction.
              2010-01-05 : release 3020
              • Fix crash caused by custom DM24 compression settings
              2009-12-11 : release 3016
              • This fixes a bug in the gdi2cd11 configuration file handling which caused the location part of a manually mapped channel name to be ignored.
              2009-12-09 : release 3012
              • Addition of a commandline tool adc-command that can be used to send calibration/mass control commands to attached ADC modules.
              2009-12-07 : release 3008
              • Improvement to the CD1.1 convertor (gdi2cd11) configuration template: Configuration of the channel description fields is now fully supported.
              2009-12-04 : release 2882
              • Fixed a bug whereby one of our packages (libev) interfered with another (libevent), causing gdi-base to lock up.
              2009-12-02 : release 2819
              • Heirarchical navigation bars have been added at the top of each CGI page.
              • Some Javascript to scroll to previous location when changing sample rates on DM24 config page
              • Added summary of Baud rates on serial port configuration page
              • Added “favicon” added to web interface.
              • Improved robustness of NMEA input code.
              • Improved interface when deleting items from network interface configuration (IP aliases, static routes, wireless network definitions, directory cleaner entries)
              • nmea-out replaced by ntp-to-nmea. This is pretty transparent as config is unchanged. New option: threshold for max acceptable μs drift from NTP.
              • libsysevents removed in favour of syslog. “System events” link gone from front page.
              • Spyrus config menu entry only displayed if spyrus present.
              • Improved user interface on environmental log plotter.
