Port Forwarding/Tunneling

[mr_anderson187]

Hey guys, wonder if you could sed a little light on a problem of mine here…


basically its like this, im at university, using a connection through a proxy that only lets HTTP though port 8080 it seems, thats all is allowed, they are debating whether or not to open ports at the minute but there is a way round this that i can use in the meantime, hopefully you get this so far

a few smart/privileged boffins, are 'i think this is it' shunnel'ing/tunnel'ing to another server that their mates have set up for them and then using that computer to bypass the proxy and thus have a full range of ports available to them..

hope your still with me so far… i was talking to one of them briefly about it, and he assures me it works, he plays guild wars non stop now because of it, and he explained to me basically what i sad above,

he talked about SSH'ing to it, and stuff, i know what SSH is by the way, i use it to connect to my webspace in uni.

ok now the problem, getting a server configured, because im at uni studying computer science, im usibg a variety of different things here, from web site development to C++ so a dedicated server was a good idea, to host sites, ip's and the like, this was concocted with G4Z and myself, he put me in contact with a dude that has the small business of small servers, they run debain linux, me being so far a linux beginner until i learn more at uni doesnt know much about this, but g4z said basically ill have command prompt access to this box (the terminal its called in linux i think we use it at uni)


MY FIRST QUESTION
what im kind of asking is, how do i go about installing software on a unix box that I only have terminal access to? I know the windows part ok I think…

MY SECOND QUESTION
ok lets say I want to play world of warcraft for example, I understand I use software to ‘tunnel’ to my server when im connected, so I open Firefox and load up my homepage, then run my program to tunnel out (im looking at putty for this) I then tunnel to my server that’s running debian linux, through port 80. this is kind of as far as my knowledge goes…

I understand that I have to run some service on this unix box that lets me forward ports, but which one? Or do I need one? More help on this would be a gem

Also another query of mine would be the program itself, world of warcraft lets say ran on port 4444, how do I stop it looking to send and receive data on 4444 and make it see my connection to my outside server? Is this all done remotely through putty? Or is there something else I should be doing? Any info would be appreciated

p.s. please before someone goes ahead and tries to flame me, dontg bother, im trying to learn here and have a way to chat with my family on skype and friends on IRC, as well as learn at university any input appreciated though

With debian you have a tool called dpkg the debian package manager, it makes installing things (and crucially getting them patched because of all the secuirty bugs been found) a breeze.

check www.debian.org the newbie howto and getting started guides. If you can, install it on a box you have physical access to. Its much better when you screw up to be able to insert the CD and start again.

[mr_anderson187]

thats good help Theanimus thanks, thats eases my mind about installing things, now just what do i need to have on the other end on the debian box, and how do i get programs like games to interface with my server?

p.s. the server's in london, im in middlesbrough lol

[TheAnimus]

understand why debian is different form most linux's FIRST

then read

[mr_anderson187]

that link is godly its basically got everything i need (except for running the server on linux of course) gonna be back there when the plan hopefully come to fruition, its nicely set out and explained simply, i love it

as for understand debain, i read about it on that link, the only way it differs is the the way its free and developed by a load of people rather than a set group of developers, i understand the kernel thing a little better now too, is that it though?

[mr_anderson187]

ok so i got my server details today, able to login dandy with them on putty and getg a terminal window to do a few things with if needs be changed my password so far just though

this is what a friend told me to use to connect (after putting the putty.exe in system32)

putty my.servername.here -D 1080 -l admin

ok so i did that ok and logged in with admin and stuff, and it appeared to be ok, he told me that doing that would enabled port forwarding on 1080, so that seemed all fine and dandy, with the connection open in the background, i went to try to get firefox (and IE) to use this, after reading a few guides it told me to use localhost in the socks server part and port 1080, but i cant seem to get firefox or IE to connect through it, any reason why?

help much appreciated

Not, really a question you have asked, but i wouldn't log in with any admin type account just for tunnelling, create a low privelaged user for that sort of thing

for the localhost thing...is localhost mentioned in your lmhosts file? try 127.0.0.1 instead

[mr_anderson187]

ive sorta moved on from my last post now, im still conecting through a uni proxy for my browsers, but im on IRC now with the tunneled connection, w00ties!

installing world of warcraft now, gonna try it, then steam

ive heard i need something like SOCKSCAP for games like this, that true?

With debian you have a tool called dpkg the debian package manager, it makes installing things (and crucially getting them patched because of all the secuirty bugs been found) a breeze.

dpkg is a bit low level for most tasks, intead I recommend apt which will automaticaly handle dependacies and download the packages you need automaticaly

Example using dpkg:

# dpkg -i apache_1.3.33-8_i386.deb
Selecting previously deselected package apache.
(Reading database ... 162737 files and directories currently installed.)
Unpacking apache (from apache_1.3.33-8_i386.deb) ...
.
dpkg: dependency problems prevent configuration of apache:
 apache depends on apache-common (>= 1.3.33-8); however:
  Package apache-common is not installed.
 apache depends on apache-common (<< 1.3.34-0); however:
  Package apache-common is not installed.
dpkg: error processing apache (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 apache

Example using apt:

# apt-get install apache
Reading package lists... Done
Building dependency tree... Done
The following extra packages will be installed:
  apache-common
Suggested packages:
  apache-doc apache-ssl apache-perl
The following NEW packages will be installed:
  apache apache-common
0 upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 0B/1224kB of archives.
After unpacking 3887kB of additional disk space will be used.
Do you want to continue [Y/n]?

As you can see, both tools detect that the package I asked for required others as dependaces, however dpkg just got stuck and gave an error, where as apt figured out what else it needed to install, and can if necessary download what you need.
