Routing question
We have Linux machine running a listserv that is unable to reach a specific ip address. I can not ftp telnet or e-mail to this address from Linux. This address is external to our network. I can reach other addresses that are external to our network from Linux. I can, however, reach this address from VM. Any thoughts as to why this is happening? We are running z/VM 4.2, SUSE 7.0 and using an OSA Express Gigabit card.

Re: Routing question
I can not ping the address. According to the network guys that is because they have the ICMP protocol blocked on there end. The ping also fails from VM.

I had similar problems. The solution was to upgrade the micro code on the card. You can check the current code level thru the HMC.
