# Configure the host whose IP address is 202.38.1.10 as the log host. Permit ARP and IP modules to 

output information with severity level higher than informational to the log host.

2)  Configure the log host: 

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 super user (root user). 

# mkdir /var/log/Switch 

# touch /var/log/Switch/information 

Step 2: Edit the file “/etc/syslog.conf” as the super user (root user) to add the following selector/action 

pairs. 

# Switch configuration messages 

local4.info    /var/log/Switch/information 

 

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

z 

A note must start in a new line, starting with a “#” sign. 

z 

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

z 

No space is allowed at the end of a file name. 

z 

The device name (facility) and received log information severity level specified in the file 

“/etc/syslog.conf” must be the same as those corresponding parameters configured in the 

commands info-center loghost and info-center source. Otherwise, log information may not be 

output to the log host normally. 

 

Step 3: After the log file “information” is created and the file “/etc/syslog.conf” is modified, execute the 

following command to send a HUP signal to the system daemon “syslogd”, so that it can reread its 

configuration file “/etc/syslog.conf”. 

# ps -ae | grep syslogd 

147 

# kill -HUP 147 

After all the above operations, the device can make records in the corresponding log file.
