Problem solved : How to find the name of your computer as it appears on the internet

Hi , I need to find my computer address, name ... so that i can ssh it from college..
What i am looking for is like ' pcname.eu.ac.uk ' for example

Thx ![

If you are going to ssh from college to home, the simplest thing would be to go to whatismyip.com on your home computer and then ssh to that address (edit: by "that address" I mean the one given when you go to whatismyip.com) from college. If your home box is behind a router, don't forget to point port 22 to your home box.

Thx for your answer...however... :

How do i point port 22? and what is that for ..does it have to be port 22?
(just a new in Linux -debian)

if you don't have a domain name, you will have to use the ip adress which is given by :

No, port 22 is just the usual port for ssh connections. Otherwise you have to configure your ssh-daemon to wait for incoming connections on other ports.

If you own a hardware router there are usually settings like "virtual server" or something like this, may be named other. To get your network secure a router in most cases rejects incoming connections on ports, unless you tell it to forward packages on these ports to a special computer in your network. That means you would have to forward port 22 on your router (if you have one ) to your computer with the sshd daemon or for example port 80 if you would like your home computer to act as a web server (with apache configured to use the standard port 80). Otherwise most routers would simply drop these packages, you could not connect from outside to your home computer.

To find your computer name on the network so that you can ssh it from anywhere in the world .. do the following :

open a shell and type:
you will see somewhere at the begining something like
where x's are numbers
Then simply do the following in a shell :
and you can see the name of your computer on the network

You may want to have a look at www.dyndns.org if you want a free third-level domain name. They require you to update your domain name every 5 to 35 days (at your choice--but not less than 5, which might be a problem, depending on your DHCP lease length or other circumstances).

It works for me, so by induction hypothesis it'll work for you too

OP: if you have a solution, I suggest you state so in the top of your first post, for two reasons:

(1) everyone who enters this thread can see your problem has been solved.
(2) everyone can see where to find a solution.

As a good example, have a look at http://www.linuxquestions.org/questi...hreadid=351315
