Telnet problem

[mpooley]

I cant seem to get this working whatever i try!

If i telnet myself eg: open localhost
for a few seconds i get "Connected to Localhost"
then I get :
"Connection closed by foreign host"

I get the same if i try to telnet in from the network.

I am using suse 8.1 - i've read the manuals- no help at all!
i've googled all round the web but nothing i've found has helped !

Can anyone help me please?

Any answer to a telnet question must contain a line that says you should be using ssh instead. Done.
Do you have the telnet-server package installed?
http://www.suse.de/us/private/products/suse_linux/i386/packages_personal/telnet-server.html
If so, "man telnet-server" should tell you how to start it, if needed.
Even better, install ssh and sshd.

it might also be that you have enabled ipchains or something like that...

But could you telnet from windows 98/2000? It seems ssh can only be run on a linux box.

To SSH from a Win32 machine use PuTTY (http://www.chiark.greenend.org.uk/~sgtatham/putty/)

cheers. I tried it and it looks cool.
But does it mean that the win32 telnet client cannot be used to connect to suse 8.1? I was able to do this with suse 7.0 without any problems:confused:

I know with Red Hat that telnet is disabled by default (security reasons as mentioned) and must be turned back on by editing a file (/etc/network/somthing-or-other) Search the site with telnel and my name I have it posted somewhere last year.

I wouldn't be suprised if SuSE has done the same thing.

You can connect to a Linux box via telnet from any OS if the telnet service is up and not blocked by the firewall.
On Redhat, the relevant file is /etc/xinetd.d/telnet and you need to set
disable = no
to turn it on and enable the xinetd daemon.
As mentioned above, this is a VERY BAD idea; use ssh (or Putty from MSwin) unless no choice. iirc, you will prob find that root cannot use telnet anyway; you'd have to login as a user, then su or sudo.
