I've tried using the actual jail name, and the hostname to be sure -

there in 8.2-9) but it sounds like it's not an issue for anyone else.
I'm defining them in rc.conf:
jail_enable="yes"
jail_list="one two three"
jail_agnet_rootdir="/usr/jail/one"
jail_agnet_hostname="one.mydomain.com"
jail_agnet_ip="123.123.123.123"
jail_agnet_devfs_enable="yes"
jail_agnet_devfs_ruleset="devfsrules_jail"
You've configured "one" and "two" and "three" in your jail_list, but
quite oddly...
You have not defined "jail_one_*" or "jail_two_*" or "jail_three_*".
I'm extremely confused as to how your jail even started!
Sorry - should have said I'd obfuscated the IP addresses and
hostnames (it's not really "one.mydomain.com" ;-) ) Unfortunately I
forgot to obfuscate the jail name as fully as I thought in the
startup lines. It should have read jail_one_rootdir &c.
As I said, it's been working happily for years on lots of different
installations and they're all configured the same. The only weirdness
is that the jail name appears in the table as it's number.
A further clarification - I know using the jail utility defaults the
jail name to that of its ID if you don't specify one, and presume this
is the mechanism messing it up here. However as I've gone to the
trouble of configuring them in rc.conf with names, listing said names
in jail_list and when commands like:
service jail start one
service jail stop one
work just fine, I don't see what I'm doing wrong! Incidentally, it
doesn't matter if I start them at boot time or start/stop later - the
jail name always sets to the jail-iD, and not the name specified. I
suspect a bug in the rc.d script, but I can't be the first person to
notice, can I??? I'll take a look.
Okay - answering my own question and solved... It's a bug (or is that a
feature?).
In /etc/rc.d/jail line 647 it currently reads:
eval ${_setfib} jail ${_flags} -i ${_rootdir}
${_hostname} \
\"${_addrl}\" ${_exec_start} > ${_tmp_jail} 2>&1 \
</dev/null
And it should (IMHO) read:
eval ${_setfib} jail ${_flags} -n ${_jail} -i
${_rootdir} ${_hostname} \
\"${_addrl}\" ${_exec_start} > ${_tmp_jail} 2>&1 \
</dev/null
Once changed, everything works find and your jails are named as per the
rc.conf file definitions. Can anyone think of a reason for NOT fixing this?
