The CTC driver was changed at some point to only use the ctc# name. I don't know that this was ever documented anywhere, but it certainly made a lot of existing literature misleading.
You need to make sure that MTU sizes match, yes. That is a typical cause of some very odd behavior. Usually not to the extent that you can't do a ping, though. When you talk to your IP networking folks, have them think of the OS/390 system as being a router in this instance, and your Linux/390 system as a host, since those are the networking roles they're filling.

That worked great. I can't use "escon0" for the ifconfig. I have to use ctc0!?!? I still can't get IP up across the link though OS/390's IP show's the link as ready. The subnet mask from my side is 255.255.255.255, but it is 255.0.0.0 from OS/390. Does my IP guy need to set me up with a subnet in the gateway instead of as a host? Would MTU size differences cause a problem? Thanks for any help.

"ifconfig" (without parameters) only shows active (up) devices. If ctc0 appears, just issue "ifconfig ctc0 <ip-address> pointopoint <peer-ip-addr> up" and things should work.
