One of my servers has a lot of IP aliases on eth0 so I thought it would be
easier to use iproute2 instead of ifconfig. I duly commented out
modules=("ifconfig") in /etc/conf.d/net (since the comments indicate
iproute2 is the default in that case). Upon reboot, the startup scripts
showed the IP aliases being added and each said [ok] but they did not
appear to be added at all. Did I do something wrong or is iproute2 not the
right tool for the job? I switched back to ifconfig and the startup
scripts work fine.
Also, each IP took a few seconds to add (this machine has 260 IPs!) - as
you can imagine it took about 15 minutes to add all the IPs before the
rest of the boot process could continue. Is there any way to speed this
up? Maybe forego the "arping" check for every single IP added?
Final problem: I tried to force full-duplex on eth0 by using ethtool in
the preup() function in /etc/conf.d/net. But now Im seeing errors like
this on my console:
eth0: Transmit error, Tx status register 82.
Probably a duplex mismatch. See Documentation/networking/vortex.txt
Flags; bus-master 1, dirty 4225325(13) current 4225325(13)
Transmit list 00000000 vs. f7c2da20.

The switch this is plugged in to (HP ProCurve) indicates that the port is
set to 100Mbit-FDx with flow control switched on, so why the errors? The
NICs on this server are 3c980-C.
