Multiple IPS - Freebsd 7.1

hi everyone,

I saw a lot of messages about this so here is it - i just patched it (took
me a day but okay :)

i just downloaded the latest src using this sup file - cvsup:
http://www.royalshells.com/download/freebsd/stable-supfile

# cvsup stable-supfile

i applied the following patch (which i changed to get to work with the
current src):
http://www.royalshells.com/download/freebsd/bz_jail7-20080727-11-at146062-Fixed_By_Sody_1.10.08.diff

to patch do:
# cd /usr/src
# patch -p6 < bz_jail7-20080727-11-at146062-Fixed_By_Sody_1.10.08.diff

after done re-compile the kernel:
# cp /usr/src/sys/netinet/in_pcb.h /usr/include/netinet/
# cp /usr/src/sys/sys/jail.h /usr/include/sys/

clean obj dir:
-------------------
# rm -Rf /usr/obj/*

compile jail and jls:
----------------------------
# cd /usr/src/usr.sbin/jail/
# make clean && make depend && make install

Hello,

does this patch maybe also makes it possible for a jail to listen at a broadcast address?

Thanks,
Nejc

I do not know what the "Fixed_By_Sody_1.10.08" part is but
it's at least based on a backlevel patch of mine so I hope
someone fixed the locking for 7.1-PRE.

I had posted a patch for 7-STABLE (7.1-PRE) last month
http://people.freebsd.org/~bz/bz_jail7-20080920-01-at150161.diff
so taking that one you could have save yourself a lot of time I guess.

In case you have changes it would be good to know what you did
or what I do not have so the do not have forks as my version will hit
HEAD soon and has changed (also the user space) since July.

Re: Multiple IPS - Freebsd 7.1

I would dearly like to see this make the 7.1 release, multi IP's in order
to support backend interfaces in jails, is something that we hit against
all the time.

Yes, seen it, your mail came in, when mine was out. UUCP works so
fine;)

You want to read the comments from then though as at least jls user
space and some kernel stuff had changed:

http://lists.freebsd.org/pipermail/freebsd-jail/2008-September/000459.html
http://lists.freebsd.org/pipermail/freebsd-jail/2008-September/000468.html

In case you have any problems, etc. let me know.

Whatever your wishes or backends are, the multi-IP jail patches will NOT
be in 7.1-RELEASE. full stop. You will need the patch. full stop.

So I am trying to get it into HEAD at the moment and in 2 months or so
once 7.1-R is out and things have settled in HEAD we can waste
thoughts on MFCing it to 7-STABLE so it could be in 7.2-R. I cannot
garantuee it will happen as the patch is intrusive and cannot keep the
KPI.

The best thing you can do until then is to actually take the patch,
test it, report problems, ...

Re: Migration of Jail from one host to another?

Quoting "Scott Lambert" <lambert@...> (from Wed, 2 Jul 2008

A little bit late, but I moved 2 ezjails today (on 8-current). It was  
setup inside a ZFS, not in an image. It worked without problems (I  
transferred the ZFS data (zfs send | zfs receive), the fstab file, and  
the ezjail config file).

You have a problem here. You may want to look into ezjail what the  
testnetmount is doing. I assume there's some problem with creating the  
md device.

I think this and the rest are followup errors of the failed mount of  
the disk image.

Bye,
Alexander.
