Everything you could want to know about CARP and FreeBSD: http://www.freebsd.org/doc/handbook/carp.html On my 8.1 box - fbsdsroute0# sysctl net.inet.carp.allow sysctl: unknown oid 'net.inet.carp.allow' So I can't say for certain but I would hazard the guess that it is not included in the GENERIC kernel.

Any news on this ? I see the same problem on our freebsd + pf + carp
installation...

Re: CARP and FreeBSD 6.3: is it working for someone?
Sorry to step in this way... I was planning to upgrade a 6.2/amd64 SMP box to 6.3, hoping I could rid myself of those deadlocks that are still occasionally plaguing that server. Now I read this thread and stopped, since I'm also using CARP on that one. Can someone confirm CARP works on 6.3 for them? bye & Thanks av. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I happened to reboot the machines now while sitting at the console. And I
noticed that the master machine emits an error like ''carp2: incorrect
hash'' while booting up. Checking the console logs showed me that the
errors have been appearing ever since I upgraded the machine. Most of the
times it was to do with carp2, once it was to do with carp1.
Here's the relevant bits of my rc.conf file from the master machine.

Hello Rakhesh,
I never had hash errors on startup for CARP, but for demote, promote you should
try /usr/ports/net/ifstated. It's working fine for me.

Re: CARP and FreeBSD 6.3
Hi,
I have two machines. Each have two interfaces, xl0 and fxp0. And each have
two carp interfaces -- carp1 (xl0 of both) and carp2 (fxp0 of both). One of
the machines is master, the other is backup.
I also have the following sysctl set: net.inet.carp.preempt -> 1
My understanding is that if I down one of the interfaces on the master
machine (say ''ifconfig xl0 down''), then both carp interfaces on the master
will be marked as down. And the backup will become the new master. Later,
when the interface is marked up (''ifconfig xl0 up''), the old master will
resume control. This is my understanding and that's how things were till
yesterday (when I was on FreeBSD 6.2/i386 with both machines).
Today morning I upgraded both machines to FreeBSD 6.3 and that does not seem
to be the case any more.
Now, on the master machine when I down the xl0 interface, only carp1 (the
group containing xl0) goes into init state (and the other machine's carp1
interface becomes the new master). Ditto for fxp0 and carp2. So in essence,
the net.inet.carp.preempt=1 sysctl does not seem to be working as expected
which is unlike how things were in FreeBSD 6.2.
Has something changed with regards to carp between FreeBSD 6.2 and 6.3? Any
one else encountering a similar problem?
I happened to reboot the machines now while sitting at the console. And I
noticed that the master machine emits an error like ''carp2: incorrect
hash'' while booting up. Checking the console logs showed me that the
errors have been appearing ever since I upgraded the machine. Most of the
times it was to do with carp2, once it was to do with carp1.
Here's the relevant bits of my rc.conf file from the master machine.
---8<--
ifconfig_fxp0="inet 192.168.10.10 netmask 255.255.255.0 polling"
ifconfig_fxp0_alias0="inet 192.168.10.11 netmask 255.255.255.255"
ifconfig_xl0="inet 192.168.20.20 netmask 255.255.255.0 polling"

ifconfig_carp1="vhid 1 pass password advskew 0 192.168.10.2 netmask

Its the same on the backup machine, except for the different IPs for fxp0
