I'm still having problems after last nights tests...
Where Miguel says you don't have to have a HOST entry, when I leave it
out, I don't get connected. When I put one in, I do get connected (but
routing is still off).
I'm now using the IUCV connection to a SLES9 31 bit with SP 1 machine
that was working when we were under z/VM 5.1. For now, I'm setting the
VSE/ESA 2.3 machines aside as it is all unsupported code and there might
be some outstanding PTFs that now come into play. (Of course that could
also be true with only SP 1 being applied on the Linux side.)
So with the following HOME statements:
HOME
205.235.227.74 255.255.255.000 QDIO1
; 192.168.099.227 HOST
; HOST PRODUCES: DTCPAR123I LINE 211: UNKNOWN LINK NAME IN HOME CMD
192.168.099.227 255.255.255.000 LLINUX27
; 192.168.099.227 255.255.255.252 LLINUX27
; 192.168.099.227 255.255.255.000 LLINUX27
; 192.168.099.227 255.255.255.240 LLINUX27
Any one that has a mask specified, connects.
When I ftp from DOS to Linux27, I get the VM banner.
IFCONFIG shows the device is up.
When I ftp from Linux27 to VM, IFCONFIG shows that it received packets,
but shows 0 transmitted for that device.
It seems to me that I can send packets to VM over the IUCV connection,
but IP isn't routing them back out.
On the GATEWAY side, I tried:
GATEWAY
; Network Subnet First Link MTU
; Address Mask Hop Name Size
; ------------- --------------- --------------- ---------------- -----
; 205.235.227 255.255.255.0 = QDIO1 1500
; 192.168.099.024 255.255.255.0 = LNEWESA4 1500
; 192.168.099.000 255.255.255.240 = LY2KESA2 1500
192.168.099.227 HOST = LLINUX27 9216
; 192.168.099.227 255.255.255.000 = LLINUX27 9216
; 192.168.099.227 255.255.255.252 = LLINUX27 9216
; 192.168.099.227 255.255.255.000 = LLINUX27 9216
; 192.168.099.227 255.255.255.252 = LLINUX27 9216
; 192.168.099.227 255.255.255.255 = LLINUX27 9216
; 192.168.099.000 255.255.255.255 = LLINUX27 9216
; 192.168.099.000 255.255.255.000 = LLINUX27 9216
; 192.168.099.000 255.255.255.000 = LLINUX27 1500
; 192.168.099.227 255.255.255.000 = LLINUX27 1500
First I commented out all other links. Just deal with one. For
LLINUX27, the oldest statement is at the bottom. 1st tried the IP
address. Then tried it as a subnet address. Then changed the MTU to
match what IFCONFIG said from the Linux side.
Nothing provided routing back to the Linux machine. I left it at the
statement that is simular to what was used in the z/VM 5.1 side, which
was:
192.168.099.227 = LLINUX27 1500 HOST
Just in case, I'm attaching the entire configuration file. Perhaps I'm
looking only at the HOST and GATEWAY statements, and I really have a
problem somewhere else (between the ears).
Thanks for any insight.

Sorry for not being clearer:
- You must have a HOME entry for each interface
- You may not duplicate any IP address in the HOME list. Each must be
unique.
- You should put each VM<-->VSE connection in its own .252 subnet. To
the
extent you are using host routes
- You must have a HOST entry in the GATEWAY for each p2p peer.
(Hmmm...Miguel: Do you still have to do that if you use a .252
subnet?)
