I've been mucking about with ucarp for the night, and come to a
standstill, hitting my head against a wall.
Basically, I'm not sure if it's my NIC's, or what- but I can't get it
to bring up the IP address?

My ucarp line looks like this:
ucarp interface=rl0 --srcip=10.0.1.242 --vhid=1 --pass=mypassword \
--preempt --addr=10.1.1.240 \
Running it looks like this:
[root at monkey ~]# ucarp interface=rl0 --srcip=10.0.1.242 --vhid=1 --
pass=mypassword --preempt --addr=10.1.1.240 --upscript=/etc/vip-up.sh
[INFO] Using [re0] as a network interface
[INFO] Local advertised ethernet address is [00:14:6c:c0:14:cc]
[WARNING] Switching to state: MASTER
[WARNING] Spawning [/etc/vip-up.sh re0]
I'm not daemonizing it, so it just hangs there. No external ping to
my new IP, and the IP address is not brought up on the machine on any
I've tried this on boxes using rl(4) (RealTek), re(4) (again,
RealTek) and xl0 (3com) cards- all doing the same thing.
Any urls or other suggestions? I thought ucarp would just add the IP
address as an alias, and start speaking CARP... ? Sadly, there's not
much documentation out there on ucarp.
Sidenote: PLEASE pretty please don't send any answers like 'just use
carp(4)', I'm trying to get ucarp working for a definite reason
here. If you haven't heard of ucarp, check it out here:
