I have setup ucarp failover using this howto, and it works great.
# /etc/network/interfaces auto eth0 iface eth0 inet static address 10.200.0.102 netmask 255.255.255.0 ucarp-vid 3 ucarp-vip 10.200.0.200 ucarp-password ourpassword ucarp-advskew 10 ucarp-advbase 1 ucarp-master yes iface eth0:ucarp inet static address 10.200.0.200 netmask 255.255.255.255
Somewhere told me that I should not use (in this case)
10.200.0.102 for anything, as it could have influence on ucarp's ability to failover.
Would it be possible to bridge
eth0, so I can get an extra IP to use for SSH, rsync and things like that without affecting ucarp?
