BIND logging

[dkim777]

I'm trying to enable BIND DNS query logging to file on my SLES 10 sp1

I have used yast to enable the logging.

if I use log type "System log" it works fine.
but if I use "File" it doesn't work.

it doesn't even create the file I've specified.

any ideas?

I've also tried to modify named.conf logging section with no success.
logging {
channel default_info {
file "/var/log/named.log" versions 5 size 5m;
print-time yes;
print-category yes;
print-severity yes;
};
channel log_requests {
file "/var/log/dnsreqs.log" versions 1 size 700m;
print-time yes;
print-category yes;
print-severity yes;
};
category queries { log_requests; };
category default { default_info; };
};
