How to open bind in iptables?
Recently I have a problem with my bind 8. when the iptables in flashed, the clients can resolve addresses with no problem but when iptables is up, I get "request time out"!!!
I wonder why in the second state, client get "server: unknown" message!!
How can I open the correspondent ports to serve DNS clients?
You must open port 53 (TCP and UDP!).
Thank you Falko,
I open these and now bind resolves its own zones addresses pretty well.
But as before I have a lot of logs like this in /var/log/message:
too many timeouts resolving 'sinfo.net/MX' (in 'sinfo.net'?): disabling EDNS
too many timeouts resolving 'mx4.nmci.usmc.mil/AAAA' (in 'usmc.mil'?): disabling EDNS
what you think about the problem?
Also other domains like google.com can't be resolved and "query refused" returned!!!
First of all, could you try to update to bind9? I'm just saying, you're using a old and insecure version of bind, try to update.
