> Can anyone tell me how to ping another computer
1. On windows 95/98: go start | run and type command
On Windows 200/xp: go start | run and type cmd
On unix/linux get a command prompt or xterm up
2. Type ping <IP_ADDRESS>, replacing <IP_ADDRESS> with the IP of the computer you want to ping. Or ping <DOMAIN_NAME> . On unix/linux systems, use ctrl-c to stop the pinging.
> or if possible, how to tell the ip's they are connected to with pinging.
You'd probably use netstat for this:
On windows:
C:\Documents and Settings\Administrator.CHARLIE.000>netstat -p tcp -an
