No, I'm not. Even because after an ifdown and ifup I can bring my inter= face with another mac address.

ifup & ifdown are Redhat-isms, and don't work right in UML. Use ifconfig, and you'll be fine. Why are you manually bringing up the interfacies anyway?

If you need to do something weird, just script it in /sbin/ifup-local. The Red Hat scripts automatically run that if it exists after the rest of the scripts run, so you can fix up anything not configured correctly there. For example, due to some weird routing, the Red Hat scripts weren't setting my default gateway properly, so I had to do something like this: #!/bin/sh [ -f /etc/sysconfig/network ] && . /etc/sysconfig/network if [ "$1" = "$GATEWAYDEV" -a -n "$GATEWAY" -a -n "$GATEWAYDEV" ]; then route del default route add default gw $GATEWAY dev $GATEWAYDEV fi Steve -- st...@si... | Southern Illinois Linux Users Group (618)398-7360 | See web site for meeting details.

The 'ip utility' comes from the iproute package: The iproute package contains networking utilities (ip and rtmon, for example) which are designed to use the advanced networking capabilities of the Linux 2.2.x kernel. That's what ifup uses to bring up and down the interfaces. I got the redhat7.2 filesystem from the uml site. I think I'll have to create my own scripts to bring the interfaces up....

Perhaps the problem is that this 'ip utility' is designed for 2.2.x kernels, yet you're using it on a 2.4.x kernel. Either way, ifconfig is the way to go.

I have indeed created my own ifcfg-eth0, without specifying the mac address, I expected that the mac address would be different.
