Cyclades-TS Installation Manual
Restart the cy_ras process using its process ID. This can be done by executing the command:
signal_ras hup
This executes the ps command, searches for the cy_ras process id, then sends the signal HUP to the process,
all in one step. Now the configuration is complete.
saveconf
is equivalent to
tar -czf /proc/flash/script -T /etc/config_files
in
standard Linux (this command is emulated by busybox on the TS and does not support the z flag).
restoreconf does the opposite of saveconf, copying the contents of the /proc/flash/script
file to the corresponding files in the ramdisk. The files on the ramdisk are overwritten.
restoreconf is run automatically each time the Cyclades-TS is booted.
Clustering
Clustering has been added to the Cyclades-TS with firmware version 1.3.0. It allows the stringing of Terminal
Servers so that one master Cyclades-TS can be used to access all Cyclades-TSs on a LAN. The master Cyclades-
TS can manage up to 512 serial ports, so
• 1 Master TS1000 + 31 slave TS1000s or
• 1 Master TS2000 + 15 slave TS2000s or
• 1 Master TS3000 + 9 slave TS3000s + 1 slave TS2000
can be clustered.
An example with one master TS2000 and two slave TS2000s is shown in Figure 4.14.
