[gentoo-user] [OT] network question

[gentoo-user] [OT] network question

[ionut cucu]

I had a buddy in my lan with whom I shared files and such. But recently
our campus network management decided to give our my dorm building
another external ip, and put a firewall( I think) between us. So now
instead of both of us having the same 141.85.0.75 I now have
141.85.0.76. So my question is, being a n00b and all, what can I use in
order to restore the direct connection? I asked my only physical
present network admin but apparently his only role is pugin computers
in switches and give us an ip so he doesn't know nothing. I did a nmap
on the gateway but I've only found 53/tcp open. I wouldn't wanna revert
to skype or other 3rd party computers since, I guess, it will
segnificantlly lower our transfer speeds, requier bothe our
presence...etc. So what way should I be heading here? Any advice is
welcome!Thanks!

If only 53 is open, you are pretty much out of luck except for two 
possible solutions:

1. The social solution
You grab a huge bag of gummy bears, carry them to your real network 
administrator and ask him to poke a hole for you and your buddy into 
the firewalls.

2. The technical solution
You get a box completely outside your compus's network into which both 
of you can ssh.

Or you get a long cross-over cable, and or long cable + 
switch......Depend how far your computers are physically seperated.

Out of interest, what happens if you nmap your buddies IP and your own 
from his box?

Same question, how far are your computers are physically separated; you could put wireless router.

That may well not be the case - it's at least worth trying.
