The reason Linux rejects the telnet from CMS is TELNET on CMS is using port 23
and Linux is only excepting connections on port 22 for SSH you can telnet to
the linux image on port 22 from CMS using the command
TELNET host 22
See if you get a connection, or at least a message that the client refused
connection.
If you are using a windows machine try to ping and tracert from your PC to the
Linux image send this data to the network guys

I can ping the CLIENT from CMS, also from CMS I can Telnet to the CLIENT (it
gets rejected by LINUX).
I'm quite sure the VSWITCH isn't a problem.. I guess my question has been
answered.. It's the network guys ... AGAIN.

If you are using a VSWITCH enter the command Q VSWITCH switch name DETAIL and
paste the response here.
Also , if you are using a VSWITCH did you authorize the client (VM user ID)
access to the vswitch.

Looking for a little help.
I'm trying to install a z/LINUX (SUSE 10) and things went along well to install
the starter system and start CLIENT.. but what next?
These are the last messages I get from the CLIENT.
*** sshd has been started ***
*** login using 'ssh -X r...@172.17.51.121'<mailto:r...@172.17.51.121'>
***
*** run 'yast' to start the installation ***
At this point what do I do?
The 3270 screen won't take any input.
If I try to PuTTY into the CLIENT I cannot connect.
Any suggestions?
Thanks
Tom
