Installation Manual

The Process Table

The process table shows which processes are running. Type ps -a to see a table similar to that below.

PID Uid Gid State Command

1 root root S /sbin/inetd

31 root root S /sbin/sshd

32 root root S /sbin/cy_ras

36 root root S /sbin/cy_wdt_led wdt led

154 root root R /ps -a

To restart the cy_ras process use its process ID or execute 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. Never kill cy_ras with the signals -9 or SIGKILL.

NTP Client Functionality

In order for the Cyclades-TS to work as a NTP (Network Timer Protocol) client, the IP address and either

hostname or domain name of the NTP server must be set in the file /bin/ex_ntpclient

The Crond Utility

To use crond, first create the following two files for every process that it will execute:

1. crontab - the file that specifies frequency of execution, name of shell script, etc. should be set using the

traditional crontab file format.

2. script shell - a script file with the Linux commands to be executed.
