Thanks to the excellent assistance from NOVELL Tech Support the problem is solved. The answer is net MASK was wrong and I had the wrong GATEWAY IP...

Tom, Check your PuTTY SSH tab to be sure you are using SSH protocol version 2. Version 1 will not work with SUSE or SLES.

Re: A little OT z/LIINUX
May be a network configuration issue? Is the client ping'able from your PC? Check all your network configurations z/VM, vswitch and parm file and make sure they are correct. If you are using a vswitch make sure you grant guess access to the vswitch. You may be able to get a shell from 3270 session it you hit enter couple of time. If you are able to, then you could also enter some Linux commands to check. Since the 3270 is a line mode console remember NOT to enter any commands that will require interaction, example vi.

Use Putty to connect to 172.17.71.121 When prompted for the user ID enter root And when prompted for the password enter the password you supplied when you configured the client.
