Hi!
I was wondering if there is way to access your system remotely, other than over telnet?
My problemis that I’m leaving for a long vacation and most definitely I’m not going to take my computer with me. But I have sites running off my server so I need to keep checking in all the time. Unfortunately I don’t have anyone who could attend to the computer in my absence.
if telnet is the only way, in that case would I beable to do such things as adding system users, changing or deleting users and most importantly restarting or starting services?
Thanks in advance

Use ssh for CLI and NX if you want GUI.
And sure you remember that you can for example run YaST ncurses
version remotely just fine over ssh without GUI.

additionally, i suggest you practice administering from afar before
you begin your vacation, or else you are likely to find bumps in the
information superhighway…

You can even run apps on the server with GUI. On the client side (from a terminal within your GUI) do:
xhost +
and then connect with ssh:
ssh -X -l username yourserver.tld
The parameter -X enables transmission of X11 connections. Response may be slow, depending on the bandwith of your connection, but it works.

No… wrong… n/a. You’d only need this if you were not tunneling
through ssh and you needed remote clients to interface directly with
your local X server and its managed display. It’s usually a security
violation and by default your local X server isn’t listening externally
to allow remote X client connects anyhow.

This alone will tunnel the X protocol across to the X server managed
display.
You do need X11Forwarding enabled in your sshd_config.

Thanks guys for your advise!
This is the first time that I’d be accessing the system remotely therefore I have to get everything extremlyclear…
The server is running linux, but the computer which I’ll have available to access from will run windows.
So If I understand you rightly, I’ll need to telnet to my system and thencall up the x11 or use command line.?
Will it be possible for anyone to suggest some good tutorial about remote access or can someone help me understand the idea in detail like step by step?
Thanks in advance!

As the
others suggest use ssh NOT telnet to get to the CLI.
From Windoze you’ll
want PuTTY installed - I don’t believe Windoze comes with anything useful
like this as standard.
For GUI you can use ssh -X … to connect a remote
X session to a local one but then you’ll need X on your local PC - so not
Windoze then :(. You’ll have to look at vnc then.
If you won’t be able to
install the necessary software on the PC you’re connecting from then it’s
more difficult.
You could possibly install webmin on your linux box and
expose it across the internet which sounds like a security disaster
waiting to happen to me but would allow remote administration using a
browser.
If you do this stick a humongous password on webmin, restrict the
IP addresses allowed to connect (if possible) and restrict the webmin
interface to only the features you need and maybe (just maybe) you’ll be
Ok.

No.
In windows you can run an ssh client called PuTTY.
It does not even need to be installed, you can run it in any windows
machine as such (like from a USB stick)

SERVER side:
In openSUSE server you can first install the YaST ssh configuration module.
YaST > Software > yast2-sshd
Then start yast again, > Network services > sshd configuration
Then System > System Services (runlevel) > enable sshd

Now you should have it running.
(If you’re behind NAT, forward the port to you server)
CLIENT side:
Try first in your lan or even ‘localhost’
like ssh localhost
Then
ssh ‘server ip address here’
That’s it
And remember to practice locally, once you’re out of physical reach to
your server, you’re on your own there 
In windows use putty as client.
Remember, if you have dynamic IP you need some service like DynDns to
find your machine in the evil Internet.
