IP Tunneling to a firewalled host
Hi ppl.
Well after a bit of snooping around, I understand that while
bi-directional communication with a host outside my firewall is
obviously possible as long as the machine inside the firewall is the
one to open up the session, I cannot use the existing IP TUNNELING code
to use such a session (opened from the inside) as an IP tunnel leading
in.
In my case a tunnel would only work one way - from inside the firewall
to the outside. getting inside would require either removing the
firewall (impossible) or the inside box to constantly maintain an open
session - and for a certain piecea-code to actually route stuff through
that session from the outside box to the inside.
to my question:
A) doesnt ANYTHING in existance that runs on linux allow me to do this?
B) OK. I need this working and nothing similar is available. So I guess
now is as good time as any to start hacking code.
<naive-optimistic-I-wanna-be-a-programmer mode on>
A - Is that stuff with which the Linux modules are written c or c++?
Some other nasty beast?
I need to know who Im fighting... :-)
B - I have some minimal programming experience.
I can pick up C/C++/whatever basics in an online tutorial.
Can someone reccomend a good book for Linux-Based (Or UNIX based if
its the same stuff) TCP/IP programming using the language that answers
Question A? - something available in Israeli book-stores is highly
preferrable. I dont feel like waiting another 3 months for a delivery
from amazon....
</naive-mode>
Thanks :-)
