I'm running Linux/390 (2.4.17) under Hercules (2.17.1) under Linux (2.4.21)
on x86, and noticed that the encapsulation between host and guest systems
for the CTC via TUN interface is different:

On the host side:

tun0      Link encap:Point-to-Point Protocol
          inet addr:192.168.10.1  P-t-P:192.168.10.2  Mask:255.255.255.255
          UP POINTOPOINT RUNNING  MTU:1500  Metric:1
          RX packets:45 errors:0 dropped:0 overruns:0 frame:0
          TX packets:55 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:10
          RX bytes:6067 (5.9 Kb)  TX bytes:5780 (5.6 Kb)

On the guest side (note the P-t-P address, too):

ctc0      Link encap:Serial Line IP
          inet addr:192.168.10.2  P-t-P:192.168.10.2  Mask:255.255.255.252
          UP POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1
          RX packets:49 errors:0 dropped:0 overruns:0 frame:0
          TX packets:40 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:5460 (5.3 KiB)  TX bytes:5471 (5.3 KiB)

How is that supposed to work?
