Operator's Guide
The same information can be obtained at the command line by using
gconfig and selecting “Version and serial number information”. If
you just want quick access to the software build number, this is
contained in the file /etc/build.version, which can be read with
the command:
eam2243 ~ # cat /etc/build.version
# Overall build version
BUILD_LABEL="platinum-stable"
BUILD_VERSION="3012"
eam2243 ~ #
The version, in this case, can be seen to be 3012.
4.2 Upgrade Methods
In order to be upgraded, the unit needs access to the latest version of
the firmware. If an internet connection is available, Güralp Systems
Ltd's software repository can be used. This is described in section
4.2.1.
If a number of units share a common network but that network is not
connected to the internet, you can make you own copy of the software
repository on a PC or laptop, which can be connected the network
either permanently or temporarily, and use that as the upgrade source.
This is described in section 4.2.2.
If one or more units to be upgraded but internet access is not available,
the new firmware can be copied to a USB storage device, such as a
memory stick, and the upgrade performed from that. This is described
in section 4.2.3.
4.2.1 Upgrading via the internet
In order to upgrade over the internet from Güralp Systems Ltd's
software repository, the unit must have its networking properly
configured. In particular, a DNS (Domain Name Service) server and a
default gateway (or defined route) must both be configured. It is
advisable to check these before proceeding.
To check for correct configuration of both of these items, issue the
command:
ping -c3 rsync.guralp.com
This will send three “echo request” packets to the GSL upgrade server
and listen for responses. If both the DNS server and the correct
gateway (router) are configured, the output will look like this:
