--Apple-Mail=_16BA7113-BA8B-4CF0-9A92-0778F2E9C75D Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Hey all, I=E2=80=99ve recently (shortly after its EoL) upgraded my = many-user-jails-box from 8.4 to 9.3 and noticed some of the jails = failing to start. They all had in common that their IP address was above = a certain suffix. Their IP addresses just were not configured on the = interface. After some investigation I found the hardcoded value _IPEXPANDMAX of 31 = in /etc/network.subr and that I basically can not run more than 31 jails = on my server anymore, if I am not willing to do some insane stuff, like = editing a non-user-servicable rc script or manually adding each IP = address or combining different schemes to add ranges (I=E2=80=99ve been = using ipv4_addrs_IF). Now, I find the arbitrary limit of 31 IP addresses cumbersome and even = more annoying that it=E2=80=99s not tuneable. The warning somehow also = did not properly find its way to my /var/log/messages, which leaves = further work for debugging. I noticed this has been fixed in = https://svnweb.freebsd.org/base/head/etc/network.subr?r1=3D267812&r2=3D271= 424 Is it possible to backport it to 9.4? erdgeist --Apple-Mail=_16BA7113-BA8B-4CF0-9A92-0778F2E9C75D Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- iEYEARECAAYFAla5aDEACgkQk9uKpYuqISRBMACfdVLxbkvAJceuFKBALYE9mrqo jY0AoIRvMNHgCrdqKhd6PkdxaqbpI6Jr =0PK5 -----END PGP SIGNATURE----- --Apple-Mail=_16BA7113-BA8B-4CF0-9A92-0778F2E9C75D--
