Pinging specific ports...

[AznMaverick]

How do i ping specific ports in windows server?

you can't. Ping is a utility to test IP connectivity to another host.

what you can do is try a direct TCP connection to the port...easiest way is "telent host port"

so basically you try to open a socket to the host. If it is immediately denied then that port is not open (you'll get a TCP reset/fin). If it times out then there are few reasons why that would happen (you didn't didn't receive the ACK). If it accepts then you get to hack the living daylights out of it.

nmap is still very powerful for checking overall open ports.

There are ways to "ping" a port by sending TCP or UDP packets to it and getting a response, something that nmap will do for you if you specify it as spidey07 said. If you don't have nmap available, sometimes simply telnetting to the port in question will provide you with minimal amount of information in the way of connectivity being open.

As a matter of fact, if you view MS information on troubleshooting email when doing MS server software, they tell you to try that with port 25. So even MS officially uses that method 🙂

And its still one of the best ways to hack. You open a socket and see what the banner returns...from there you know what service is running on that port.

Also one of the old school tricks we used to use (circa 1990) to forge e-mails. I'll still never forget sending my roomate a "you have been caught hacking and are immediately suspended from Purdue University. Please see my office at 7:00 am sharp. Signed Gene Spaford, director of the School of Computer Science, Purdue University"

My did he crap bricks...asking us what he is supposed to do. We let him go one for a few days before telling him.

good times, good times.
