forcing connection (newbie question)?
Hello! I work in a tiny company and we have a SuSEfirewall, wich i can not access or influence, cause its set up by a 3rd Person. LINUX_HOME FIREWALL LINUX_WORK ------------> | Traffic from LINUX_WORK to external is allowed. I´m root on LINUX_HOME and LINUX_WORK. Can i somehow force a ssh connection from LINUX_WORK to LINUX_HOME (the other way is not possible due to the firewall) so that i can connect from HOME to WORK? I guess its not possbile, but worth to ask ;) Cheers, Mario
Hi Mario, yes, it's possible! Ask google about ssh-tunneling, you can open an ssh-tunnel from your PC at work to your home-PC. To the firewall it looks like a normal ssh-connection, but you can tunnel about everything through it in every direction. I've not yet set it up myself (I'm the firewall admin at home and at work ;-) ), but there is such thing and it works! But be very careful with it, your opening up a backdoor to your network at work!!! Best regards, Ralf Mario Ohnewald wrote:

True, the big disadvantage! But this should just be a little issue in compare to a whole M$ Network ;P
Best regards,

I?m root on LINUX_HOME and LINUX_WORK. Can i somehow force a ssh connection from LINUX_WORK to LINUX_HOME (the other way is not possible due to the firewall) so that i can connect from HOME to WORK?
2 ways: 1. ssh tunneling 2. vpn connection (e.g. vtund) BUT: if you're unable to connect from home to work, did you think about the WHY? If you Homenetwork is exploited (mostly your home network isn't protected like the company one) everyone who want can connect from you into the company network. so you're able to penetrate the firewall to 100% ... not what the '3rd person' want i think.

Yes, indeed i did! And of course there are reasons!

3rd person wanted to protect the network from external, this is actually starting from internal. I know the 3rd person, close friend of mine, and i do not wanna push him into anything, thats why i wont tell him (he actually is in this list and might read it.) And even if the Windows Admin reads this, i do not care. I am not doing anyting forbidden! Someone has to explore the Network. I am abou to become a System-Admin. Well, thats what i wanna become. This is getting into a social issue, but i know what i am doing. This is all about exploring things, what do u expect from a sys-admin? ;P If the thinks will work like i have them in mind, i will of course tell the responsible ppl about it. I am not a kiddy! (oh my god, i sound like one!)
