Hi Ron, I am using the HMC, Operating System Messages, which limits what you can do. I'll check out the ascii console.
Yes, I have two ports. I have two OSA/Express cards in the System. One port on each card is ethernet, the other is OSA-ICC. The ethernet ports on both cards are shared across all LPARs. I wish the HMC Op Sys Msgs allowed you to cut and paste... Let me see if I can get the ascii console working, and check on the files you were asking about. Dave Dave Stuart Prin. Info.

You say both ports. This implies more than one interface. What is your default route set to in /etc/sysconfig/network/routes? Is it set to one of the active interfaces? When you say you are getting martian messages, could you elaborate? Could it be that the firewall got turned on? The interface might be up, but the firewall is disallowing all traffic. Also, there is some sort of OSA support tool that our zOS guy uses. He can go look at the OSA and the what LPARS are attached to an OSA and what addresses they are using. The people who know how to use this tool are out today at a meeting. Do you all have someone who can look at the OSA with this tool and find out if the Linux LPAR is really attached and what address it is using. In my limited experience running Linux in LPARS, there are only a few files that have to be right to get the network up. /etc/sysconfig/network/persistentnetworkname (in our case) ifcfg-qeth-bus-ccw-0.0.a100 /etc/sysconfig/hardware/hardware name (in our case) hwcfg-qeth-bus-ccw-0.0.a100 /etc/sysconfig/network/routes And possibly /etc/hosts Also, if you all are a member of SHARE, there was a presentation some time back that included some tips on how to get the "network" up when it does not want to come up. If you do not have ascii console mode running, it might be worthwhile to use google to find this presentation. (A lot of the presentations are on the linuxvm.org website.) If I remember correctly, the presenter said that by using a few echo commands to the right places, you could get a network up. I never tried it though.
