Experts,

       I need the command to ssh into a Linux box and check to see if port 22 is open. Do I need PUTTY to ssh into a Linux box from a Win2k3 server?

Thanks, Missymadi

run following command on linux :  netstat -nan | grep 22

you should expect this output  
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 4324/sshd ( example)

If the command output return ‘LISTEN’, mean the particular port is open or listen on network.

Yes you can use putty to ssh into linux server

Yes, putty would suit. Windows server doesn't normally come with an SSH client.
