Various recent threads about networking issues

[Janina Sajka]

Hi,

Well, my issue wasn't two nics, but two ip addresses on one nic, neither
of which was coming up.

The new scripts appear to help. At least, I'm back on line, though I
can't bring up both eth0 and eth0:0 on boot (unless with rc.local,
perhaps).

Done, with rpm --replacepkgs because I think I'd already downloaded this
rpm last night but had not followed the procedure you outline.

Removed two ifcfg-eth0* files by hand.

ifconfig eth0 reports correct mac address.

The r8169 driver is not back in modprobe.conf, but it is listed out by
lsmod. That's good enough for me.

I have static ip addresses, so tried bringing the ifcfg-eth* files back
and running ifup. That doesn't work--system just hangs without returning
the shell prompt.

Configuring by hand with ifconfig works.

Further expirimentation indicates that putting ifcfg-eth0 back in
/etc/sysconfig/network-scripts is OK. I get my internal, nat'd address
on boot. But, putting ifcfg-eth0:0 back causes only the eth0:0 to end up
configured. Is it being reconfigured?

In other words, I can't seem to auto configure two addresses on the same
interface, so I have opted to load the nonroutable 192.168. address on
boot, and apply the routable by hand. I may try adding a statement to
rc.local--but I don't expect to do much booting with this machine.
Things should just stay.
