Thank you stevean kind co-operation.
as you said I modified the logging sections. but still external domains are unable to resolve. I wanted tell you one more thing when I reassign my old IP which is 212.119.64.12 then everything works fine (I mean interal autherative domain and external yahoo etc.... )without any problem options { directory "/var/named"; listen-on port 53 { 212.119.64.228; 212.119.64.226; 212.119.64.12;}; version "Have a nice day!, Good Bye"; recursion yes; notify no; }; logging { channel bind_syslog { file "/var/log/named/bind_sys.log" versions 3 size 5m; # syslog daemon; severity info; }; category default { bind_syslog; }; }; log file bash-2.03# tail -f /var/log/named/bind_sys.log zone 0.0.127.IN-ADDR.ARPA/IN: loaded serial 3 zone makksab.com/IN: loaded serial 2005032202 zone localhost/IN: loaded serial 3 zone cyberiamall.net/IN: loaded serial 2005032202 zone kalam.net.sa/IN: loaded serial 2005032202 running sloading configuration from '/etc/named.conf' no IPv6 interfaces found zone 0.0.127.IN-ADDR.ARPA/IN: loaded serial 3 zone makksab.com/IN: loaded serial 2005032202 zone localhost/IN: loaded serial 3 zone cyberiamall.net/IN: loaded serial 2005032202 zone kalam.net.sa/IN: loaded serial 2005032202 running -----Original Message----- From: bind-users-boun...@lists.isc.org [mailto:bind-users-boun...@lists.isc.org] On Behalf Of Steven Carr Sent: Thursday, December 25, 2014 12:29 PM To: Bind users Subject: Re: can't-resolve On 25 December 2014 at 08:05, Mohammed Ejaz <me...@cyberia.net.sa> wrote: > logging { > > channel querylog{ > > file "/var/log/querylog"; > severity debug 10; > print-category yes; > print-time yes; > print-severity yes; > }; > > category queries { querylog;}; }; OK so you only have query logging enabled, enable additional logging and it will more than likely point you to the error, BIND is issueing a SERVFAIL for the query which means it will dump an error message into syslog (when configured). Something like the following will pump all other messages to syslog... logging { channel bind_syslog { syslog daemon; severity info; }; category default { bind_syslog; }; }; Steve _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users -- _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
