is there a way i can access my linux computer thru another computer other then just samba i mean like to run commands or list a dir or something like that ? maybe even something other then an ftp aswell
not sure how telnet works at all but maybe that???
thru like a windows machine or maybe thru a different linux machine

i know this prolly sounds dumb....

try vnc

It is a tool that allows you to connect to your Xserver (GUI and all) from a remote machine , windows or linux.

I have never set it up before so I cant help you there but I have seen it being used before and it is really good.

There are less processor hungry services as well like telnet etc.

to open a telnet session just type tellnet in a windows or linux machine.
then

open mydomain.com.au (replacing the domain name with your domain or ip address)

then log on a one of your users.

The terminal will then act as a linux command shell.

You are looking for ssh. It allows secure logon from one system to another and is used regularly by sys admins. You're shell will look the same if you use ssh, while telnet is very limited .

I've always used PuTTY (http://www.chiark.greenend.org.uk/~sgtatham/putty/), which now has been ported to Unix, so it may also work on Linux.
