Connecting to Outside World
Hi all,
I am behind a firewall so because of that i am not able to connect to pc's outside my LAN through ssh or telnet.Is there any other way to connect? --CooL |
You'll have to talk to your admin and have him allow outgoing telnet/SSH traffic. I'f your the admin, what kind of firewall are you using? Is it an appliance like a Linksys router or is it another Linux box?

I am not the admin but i dont want to ask him.I want to do something on my own.something like port forwarding(I think) etc can be used.Tell me how to use these techiniques without having admin permission for telnetting to outside world.

there is an http telnet gateway at http://www.mosha.net/01-telnet-gateway/telnet.shtml.
if the firewall uses only port blocking (i.e. no active filtering) perhaps you can run telnet/sshd on port 80 of the machine you are trying to connect to.... I am assuming you have permission to access internet resources through the firewall. |
Hi,
But the link u provided is not working.may be the url is wrong.can u repost the correct url?? Thanx |
it's the right url; sometimes it just don't work. sorry.
why dont you wirte one yourself? listen on port 80 and forward any request to port XXX on the destination machine? netcat might be useful... wont be so hard, plus itll be a good programming exercise. there are millions of linux networking programming tutorials for C. sh1t like this don't come easy. |
