Dnscache access little secret

My friend just install dns server using djbdns, he use two component in djbdns:

  • tinydns
  • dnscache

After follow all setup in tutorial, he try to test the dnscache :

mail# dig yahoo.com

; <<>> DiG 9.3.4-P1 <<>> yahoo.com
;; global options:  printcmd
;; connection timed out; no servers could be reached
mail#
checking service, maybe not running :

mail# ps -ax | grep dns

  580  ??  I      0:00.00 supervise tinydns
  582  ??  I      0:00.00 supervise dnscache
  878  ??  I      0:00.01 /usr/local/bin/dnscache
  880  ??  I      0:00.00 /usr/local/bin/tinydns
  914  p0  R+     0:00.00 grep dns

mail# /usr/local/etc/rc.d/svscan.sh restart

Stopping svscan.
Starting svscan.

seem ok now, try again :

mail# dig yahoo.com

; <<>> DiG 9.3.4-P1 <<>> yahoo.com
;; global options:  printcmd
;; connection timed out; no servers could be reached

Something wrong, I check another suspicious place :

mail# cd /etc/dnscache/root/ip/
mail# ls

127.0.0.1

Hmm….

add access to network to use dnscache :

mail# touch 192.168.1
mail# ls

127.0.0.1       192.168.1

trying again :

mail# /usr/local/etc/rc.d/svscan.sh restart

Stopping svscan.
Starting svscan.

mail# dig rasyid.net

; <<>> DiG 9.3.4-P1 <<>> rasyid.net
