Re: Problems chrooting BIND 9.2.2 in a Solaris 8 box

Hi,

It appears that named is trying to look for its hosts files into /dns/etc, 
since this should be the specified directory in named.conf.
Probably this directory (/export/home/dns/dns/etc) does not exist. 

Have you tried to do the chroot directly from named, by its -t flag?
AFAIK, Bind 9.2.2 provides the ability to chroot itself, after it processes 
all the command line arguments, with the -t flag.

Instead of 
# /usr/sbin/chroot /export/home/dns /usr/local/sbin/named -u named

Try
# /usr/local/sbin/named -u named -t /export/home/dns

Cheers,
