I find that I'm always stumbling around when it comes to
understanding the configuration and use of TCP/IP in VM.
We have three VSE virtual machines which use TCP/IP in VM as their
gateway, connected via virtual ctca's. The IP stacks are working
correctly in two of the guests, but not in the third. It previously
worked and no changes have been made. I can see nothing wrong from
the guest's point-of-view. It comes up as if full IP connectivity is
there, but it's not reachable from the outside nor can it reach the
outside. This suggests to me that the connection between VSE and VM
is working fine but that the gateway function in VM TCP/IP is down
for this one IP address. I can't easily bounce the VM TCP/IP machine
because others are using it.
There must be some diagnostic commands to help figure out what's
going on, but when I look at the TCP/IP Planning and Customization
Manual I'm not finding them. How can I proceed?
We're on z/vm 4.2.
