Correct me if I'm wrong (I haven't played with MVS TCPIP definitions much), but in this statement: LINK CTC37 CTC 1 CTC3X7 doesn't the "1" say to swap the read channel with the write channel? If so, I would think that is your problem, since the entry in chandev.conf ctc0,0x0d33,0x0d32,0,3 says to do exactly the same thing. The fact that the ifconfig output you show lists 5 errors, all of them "carrier" errors would seem to bear this out.

We have a need to connect the zOS system to a linux (SuSE v8) system thru the internal escon ctc for ftp & lpr traffic. We got both sides to connect so far, but whenever we ping the zOS system from the linux system, the ctc goes down on the zOS side. If we ping the linux system from the zOS system, the ping times out. The ctc is defined to zOS as followed: DEVICE CTC3X7 CTC B72 LINK CTC37 CTC 1 CTC3X7 ; HOME ; Local host's Internet addresses 10.0.3.2 CTC37 ; BEGINRoutes ; Destination Subnet mask First Hop Link Name Packet Size ; ---.---.---.--- ---.---.---.--- ---.---.---.--- --------- ----------- ROUTE 10.0.3.1 255.255.255.0 = CTC37 MTU 1500 The ctc is defined to the linux system as followed: - in chandev.conf: ctc0,0x0d33,0x0d32,0,3 - ifconfig: ctc0 Link encap:Serial Line IP inet addr:10.0.3.1 P-t-P:10.0.3.2 Mask:255.255.255.0 UP POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:5 dropped:5 overruns:0 carrier:5 collisions:0 txqueuelen:100 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) --------------------- We got ctc traffic between zOS systems successfully so it's not the hardware.
