Step 2: Create a subdirectory named Device under directory /var/log/, and create file info.log under 

the Device directory to save logs of Device. 

# mkdir /var/log/Device 

# touch /var/log/Device/info.log 

Step 3: Edit file /etc/syslog.conf and add the following contents. 

# Device configuration messages 

local4.info    /var/log/Device/info.log 

In the above configuration, local4 is the name of the logging facility used by the log host to receive logs. 

info is the information level. The Unix system will record the log information with severity level equal to 

or higher than informational to file /var/log/Device/info.log. 

 

Be aware of the following issues while editing file /etc/syslog.conf: 

z 

Comments must be on a separate line and begin with the # sign. 

z 

No redundant spaces are allowed after the file name. 

z 

The logging facility name and the information level specified in the /etc/syslog.conf file must be 

identical to those configured on the device using the info-center loghost and info-center source 

commands; otherwise the log information may not be output properly to the log host. 

 

Step 4: After log file info.log is created and file /etc/syslog.conf is modified, you need to issue the 

following commands to display the process ID of syslogd, kill the syslogd  process and then restart 

syslogd using the –r option to make the modified configuration take effect. 

# ps -ae | grep syslogd 

147 

# kill -HUP 147 

# syslogd -r & 

After the above configurations, the system will be able to record log information into the log file. 

z 

Send log information to a Linux log host with an IP address of 1.2.0.1/16; 

z 

Log information with severity higher than informational will be output to the log host; 

z 

All modules can output log information.

Before the configuration, make sure that there is a route between Device and PC.
