Subject: First time Linux under S/390
Configuring my first Linux under S/390 and cannot get Linux to communicate
with the network. Following is a brief overview of the environment.
We run a class C network 192.168.168. with a subnet mask of 255.255.255.128.
Existing network runs on low order, Linux network runs on the high order.
Connectivity between the network to z/VM on a Multiprise 3000 H30 is
provided by a Bustech MAN device owned by VM TCP/IP.
192.168.168.20 is the VM stack
192.168.168.129 is the Linux stack
192.168.168.35 is a PC on the network
>From a Z/VM CMS virtual machine I can ping all resources.
>From Linux, I can ping VM but not the PC.
>From the PC, I can ping VM but not Linux.
So Linux appears to not be routing to the network. Here is the detail stuff
for those of you in the know. Any advice and guidance would be appreciated.
Thanks
