Tools Ports In Unix

Please could some one tell me how to open a port in unix or to check if a port is open.
# 2  
Hi,

To check if a port is open you could run the netstat command.

netstat -l shows what processes are listening along with their ports


You could also run nmap on your machine, this will also show whats ports are open.

Did you mean netstat -n or netstat -an ?
