The operations here are performed on SunOS 4.0. The operations on other

manufacturers’ Unix operation systems are similar.

Step 1: Execute the following commands as the superuser (root user).

# mkdir /var/log/3Com

# touch /var/log/3Com/information

Step 2: Edit the file "/etc/syslog.conf" as the superuser (root user) to add the

following selector/action pair.

# 3Com configuration messages

local4.info /var/log/3Com/information

When you edit the file "/etc/syslog.conf", note that:

■ A note must start in a new line following a "#" sign.

■ In each pair, a tab should be used as a separator instead of a space.
