[Pdns-users] [Q] pdsn recursor chroot environment error : rec_control = Fatal: Unable to receive message over control channel: Success

[J4K]

Hi there,

	I have a small question about running the recusor in a chroot
environment.    It will be used to provide postfix and spamassassin with
RBLs.

It works fine, but is inaccessable via the rec_control command:

# rec_control --socket-dir=/var/spool/powerdns/var/run ping
Fatal: Unable to receive message over control channel: Success


I have set up the chroot to allow acesss to socket and pid files:

root at sa51 /var/spool/powerdns/var/run # ls -l
total 0
lrwxrwxrwx 1 root root 36 Oct 27 15:37 pdns_recursor.controlsocket ->
/var/run/pdns_recursor.controlsocket
lrwxrwxrwx 1 root root 26 Oct 27 15:37 pdns_recursor.pid ->
/var/run/pdns_recursor.pid

The files exist:
srwxr-xr-x 1 root root 0 Oct 27 15:38 /var/run/pdns_recursor.controlsocket
srwxr-xr-x 1 root root 0 Oct 27 15:38 /var/run/pdns_recursor.controlsocket

Process is running:
pdns     20091     1  0 15:38 ?        00:00:00 /usr/sbin/pdns_recursor
--daemon

The recursor.conf has:
allow-from=127.0.0.0/8,::1/128
chroot=./
config-dir=/etc/powerdns/
max-cache-entries=10000
max-cache-ttl=1440
max-negative-ttl=900
max-packetcache-entries=5000
setgid=pdns
setuid=pdns

The /etc/passwd entry is:
pdns:x:115:120:PowerDNS,,,:/var/spool/powerdns:/bin/false

The O/S is Debian Squeeze
Linux sa51 2.6.32-5-amd64 #1 SMP Mon Oct 3 03:59:20 UTC 2011 x86_64
GNU/Linux


Does anyone know how to get this running correctly in a chrooted
environment?

Cheers,
S
