Typical Syslog Configuration Example

Configuration of Log Host

The configuration, implemented on SunOS 4.0, is almost the same as that performed on the Unix operating system of other manufacturers.

1Execute following commands as root (supervisor)

#mkdir/var/log/Router

#touch/var/log/Router/config

#touch/var/log/Router/security

2Edit the file /etc/syslog.conf as the root and add the following selector/action pairs.

#Router configuration messages

Local4.crit /var/log/Router/config

When editing /etc/syslog.conf, note the following:

■The comments can only be in separate lines, beginning with character #.

■The selector/action pairs must be separated with one Tab instead of a space.

■There must not be redundant spaces behind the file name.
