Appendix H. Configuring a System Log Server

Because the router’s memory cannot hold as many messages as a computer with a hard drive, you can have the router send its System Log messages to a server on the network.

The ability to receive system log messages is most common on Unix-type sys- tems. The following section describes how to set up a syslog server on Red Hat Linux.

H.1 Red Hat Linux

All Linux distributions run a syslog daemon by default, but usually the daemon won't listen for system log messages from the network. You will need root ac- cess to carry out the following steps:

1.First we need to configure the syslog daemon to listen on the network:

Edit /etc/sysconfig/syslog and add the options -r-xto the line SYS- LOGD_OPTIONS. Save the file.

#Options to syslogd

#-m 0 disables 'MARK' messages.

#-r enables logging from remote machines

#-x disables DNS lookups on messages received with -r

#See syslogd(8) for more details

SYSLOGD_OPTIONS=" -r -x -m 0"

2.We also want to configure the system logger to use a specific file for mes- sages from the router. We'll assume that the router has been configured to use facility local5.

Edit /etc/syslog.conf and add a line for the router:

This says that all messages with facility local5 should be logged in /var/log/ router.log. (Note that the two portions of the line in syslog must be sepa- rated by tabs. Don't put any spaces between the two.)

3.Now restart the syslog daemon:
