One day, I need to rsync between two Linux servers. And i have to know that only port 80 is opened between those. So use the following command so that rsync can use port 80 rather than 22. #rsync -e "ssh -p 80" -avp /tmp root@remotehost:/tmp Hope that somebody find this post useful.
Purpose - Logging to remote log server instead of keeping log on locally for security reason.
In our case, we will send logs messages to a server with IP Address ( 192.168.1.2 ) How To #vi /etc/syslog.conf
find the following line *.info;mail.none;authpriv.none;cron.none /var/log/messages
change it to *.info;mail.none;authpriv.none;cron.none @192.168.1.2
and restart the syslog server #service syslog restart
