We finally got our z/VM license and dusted off a couple of our linux virtual machines. On our sles8 machine, we can connect to some external sites but not to others:
linux04:~ # uname -a Linux linux04 2.4.19-3suse-SMP #1 SMP Mon Mar 3 14:07:59 UTC 2003 s390 unknown linux04:~ # linux04:~ # telnet www.ibm.com 80 Trying 129.42.19.99... Connected to www.ibm.com.

On our sles7 machine we don't see the problem:
linux05:~ # uname -a Linux linux05 2.4.7-SuSE-SMP #1 SMP Tue Oct 30 22:39:07 GMT 2001 s390 unknown linux05:~ # linux05:~ # telnet www.ibm.com 80 Trying 129.42.16.99... Connected to www.ibm.com.

I tested this using the exact same ip addresses and osa device numbers (not at the same time of course). So it must be something in our sles8 configuration that is causing the problem, but I have no idea what. Below are the ifconfig and route displays for each machine (sles8 then sles7):
linux04:~ # ifconfig eth0

Does anyone have any ideas ??
Thanks, Greg Smith
