Unless you a hidden behind some type of proxy server GRC will scan your
IP, if you are behind a server it will scan that server

There are various portscan utilities you can run but check your ISP's T&Cs
first because many of them have a prohibition against running portscans
against other machines. Some just say "no portscans", some add blurb about
permission from the owner of the machine being scanned (more sensible, it
can help to actively fix things with a friend on-line). Some probably
haven't even considered it.

Port 80 is a web server, or is my wetware in Friday night mode?

If you're checking a specific machine/port combo, check for some
commands you can use, and try using telnet. I regularly do this with
port 119 on my ISP news server, and log the results of a LIST command.

A lot of the basic commands and responses on the Internet are human-
readable ASCII text.

I doubt that there are any Web-based tools that allow you to scan a
remote IP address because it would be open to abuse. Most ISPs
(including yours) prohibit port scanning unless you have the explicit
permission of the owner of the remote system.

If you just want to check whether a remote system is running a Web
server, either fire up your favourite browser and type
"http://1.2.3.4" or, in a DOS window, type "telnet 1.2.3.4 80", where
"1.2.3.4" is the IP address of the target system. The latter will
show you a blank telnet window if it works or an error message if
there's no response from the remote machine.

If you really want to do a port scan and have permission to do so,
there are several tools that will do it but you may well have to run
them on a better operating system.

Mike.

I was assuming he wanted to find which ports rather than check a few
specific ones. I guess you could try a telnet to each port in turn but it
might be slow. Automated stuff such as nmap (of Matrix fame) is probably
not approved by some ISPs. I use telnet to check on specific ports, most
recently port 119 as well.
