ssh-copy-id user@host

find the zombie processes.

ps aux | awk ‘$8 == “Z” { print }’

apt-cache search $file

Whats running on this port.

$ sudo netstat -tulpn | grep :portnumber

This is how we can get the mac addresses of all the interfaces on the system.

$ /sbin/lspci -v | grep -i “Device Serial Number”

$ ps axu | grep [a]pache2

grep processes list avoiding the grep itself

$ date –set=”$(ssh user@server ‘date -u’)”
