Hi, Lutz.
www.vm.ibm.com has moved from 204.146.134.198 to 204.146.134.18.
DNS updates are working their way through the Internet, so it's not just
a German/European problem.

Thank you for your explanation and the URL, Vic.
I'd like to check it - if www.vm.ibm.com goes online again :-)
It seems to be off-line since last Friday or Saturday :-(
Does anybody know the reason - or is it only specific German/European
problem ?
ciao Lutz

There are a few VMLAN fixes out since 0404RSU. From recent experience I'd
suggest you get right up to date and try again (the qeth driver on the
guests
other than X might need an update as well, although it strikes me as odd
that
the SLES 7 system works talking to the SLES 9 SP2 given that its qeth is
probably older than the Debians'...).
The z/VM team maintains an excellent resource that talks about (among other
things) z/VM maintenance levels in support of virtual networking:
http://www.vm.ibm.com/virtualnetwork
Look for the "Virtual Switch and Guest LAN CP Maintenance levels" link.

No need to be concerned about this. At earlier levels the display shows
the
natural network mask (i.e. as if you weren't subnetting) instead of the
actual subnet mask in use. On z/VM 5.1 the subnet mask display is removed
(replaced by the MAC address, like the multicast display).
