I know that we can now do multiple IPs in a jail, and I have a
configuration that works for it.
jail.conf:
testjail {
jid = 100;
host.hostname = testjail.local;
ip4.addr = 'em0|10.20.190.190/24';
ip4.addr += 'em0|10.20.190.191/24';
path = /jails/devel/ROOT;
allow.mount.devfs;
mount.devfs;
allow.sysvipc;
exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
exec.prestart = "/jails/devel/prestart.sh";
exec.poststop = "/jails/devel/poststop.sh";
exec.consolelog = "/jails/devel/console.log";
}
This works great, my question is now that I have this figured out and I
am done testing it, how can I apply it to a running jail without
rebooting the jail?
I tried using:
jail -n testjail -m 'ip4.addr='em0|10.20.190.191/24'
This replaces the IP on the jail.
Then I tried using:
jail -n testjail -m 'ip4.addr+='em0|10.20.190.191/24'
I get an error "unknown parameter ip4.addr+"
Am I stuck waiting until after hours to add the secondary IP when I can
reboot the production jail? Or is there another way I haven't figured
out yet to add the secondary IP to the running jail?
