By default almost all logfiles are located under /var/log directory (and subdirectory). You can change to this directory using cd command but you need to be the root user. You can use less, more, cat or tail command to see the logs.
Go to /var/logs directory:# cd /var/logsView common log file /var/log/messages using any one of the following command:# tail -f /var/log/messages
# less /var/log/messages
# more -f /var/log/messages
# tail /var/log/messages
You can set Up A Central Syslog Server, check the logfile remotely of another system on same network, as mentioned in this links:
