Re: [PLUG] Find Open Ports
|
If I were you I wouldn't portscan your office network,
Have you considered using http://eyeos.org/
It is a cloud computing desktop that you can install on any webserver, written in PHP5
It's not linux, but it has a web browser, and many other apps. Is port 22 open at your work? I thought 23 was the telnet port and port 22 was ssh. I find most anything I want to do can be done with ssh, but if you must have a web browser consider eyeos. I have a copy in a password protected directory with the .htaccess chowned to root, because I am a little paranoid. It's something to think about.

My employer is very aggressive in closing off ports. This makes it hard for me
to access my home network from work. Luckily, port 23 is open so I can ssh
in, and of course, port 80 is left alone.
However, I've got several special web pages that run on computers behind my
firewall. I access them through port forwarding to non-standard ports (such as
81 & 82).
Unfortunately, since my employer blocks these ports, I can't use them. I do
have unlimited discretion, however, in assigning my programs to whatever port
I desire.
So.... if I knew which ports were NOT blocked, I could use those.
BUT... How do I check to see if what ports are available?
So far, I've been able to come up with 2 ideas: 1) scan every port, and 2)
try ports manually one at a time.
I could run a portscan on my portable, but that would undoubtedly raise all
kinds of alarms. Also, I'd have to be sure I was connecting to something that
had those ports active.
Does anybody have any suggestions on how to test to see if a series of ports
is not filtered, or have a suggestion of ports that I could test manually
through trial and error?
