 JAIL and DHCP glitches
Author: VVK 
Date:   27-12-01 09:03


I've been running jail successfully for almost 2 years now. Today my cable
company changed static configuration to DHCP one. I've reconfigured my to use
DHCP, however, jail would not work.

in /etc/rc.conf:

ifconfig_ed0_alias0="inet netmask"
ifconfig_ed1="inet netmask"
ifconfig_ed1_alias0="inet netmask 0xffffffff"
inetd_flags="-wW -R 1024 -a"
# using this to mount drives/directories from jail

in /etc/dhclient.conf

send host-name "crxxxxxxx-E"; # Put your client IP here
request subnet-mask, broadcast-address, routers, domain-name-servers;

now, the problem is with the following:

jail works fine (SSH/TELNET/etc) when i don't have /etc/resolv.conf. however,
i cannot connect to any host from jail as it cannot resolve it. as soon as i
put it in with correct DNS numbers, it starts giving me hard time: connects,
say, to port 22, but no SSH header is displayed and same with other daemons..

inside jail, i have the following:

root@me:/home/me>>ifconfig -a
ed0: flags=8843 mtu 1500
ether 00:50:ba:cd:9a:fa
ed1: flags=8843 mtu 1500
inet netmask 0xffffffff broadcast
ether 00:50:ba:cd:b9:60
lo0: flags=8049 mtu 16384

there is no address associated with ed0 (my external nic) while in host
system it shows the following:

ed0: flags=8843 mtu 1500
inet 24.xx.xx.247 netmask 0xffffff00 broadcast 24.xx.xx.255
ether 00:50:ba:cd:9a:fa
ed1: flags=8843 mtu 1500
inet netmask 0xffffff80 broadcast
inet netmask 0xffffffff broadcast
ether 00:50:ba:cd:b9:60
lo0: flags=8049 mtu 16384
inet netmask 0xff000000

output of jail:
Skipping disk checks ...

^^^^^^ e
What might be the problem? Have you ever heard about this? Is there a fix?
Would greatly appreciate any helo/hints.
