Hello Damoen,
thanks for the mail - yesterday I somehow skipped the mail to freebsd
forum when replying to you.
Some minutes ago i have found another error in my script:
run "/sbin/ifconfig_carp0 vhid 1 pass newpass 192.xx.xx.1/24"
run "/sbin/ifconfig carp1 vhid 2 pass newpass 192.xx.xx.2/24"
run "/sbin/ifconfig carp2 vhid 3 pass newpass 192.xx.xx.3/24"
ok is:
run "/sbin/ifconfig_carp0 vhid 1 pass newpass 192.xx.xx.1/24"
run "/sbin/ifconfig_carp1 vhid 2 pass newpass 192.xx.xx.2/24"
run "/sbin/ifconfig_carp2 vhid 3 pass newpass 192.xx.xx.3/24"
So the difference is using "_" underline sign for carp1 and carp2.
I try to get new ideas from your script.
Kind regards,
Peter
