check ports on server
Hi All,

I've been using this to verify if ports is open on a server. For example I would like to check port 5887, "telnet ip.of.server 5887" using on dos. If there's response on it then I can say it's open, if not then it's close.

Is that assumption accurate?

Thanks for any comments you may add.

netstat is usually best to use but lsof also shows similar info
ie.
lsof -i | grep port#
