Hi,<div><br></div><div> Thanks for the advices, i've run the test (named -g after kill) and the realize the zonecheck of the <a href="http://AFNIC.FR">AFNIC.FR</a> has passed.</div><div><br></div><div> As I didn't do nothing in between, I guess this was maybe a temporary error of the <a href="http://AFNIC.FR">AFNIC.FR</a> zonecheck utility (which says UDP port 53 was not reachable).</div>
<div><br></div><div> Is there a mean to query the DNS Server on UDP port 53 with something like dig ? so I can be sure that it's not my server that is wrong ? </div><div><div><br></div><div>I'll keep in mind the lsfo -i :53.</div>
<div>For nmap, the correct command was nmap -sU ns1 -p53</div><div><br></div><div><br></div><div>Thanks for your help,</div><div>Thomas.</div><br><div class="gmail_quote">On Thu, May 28, 2009 at 17:12, Peter Dambier <span dir="ltr"><<a href="mailto:peter@peter-dambier.de">peter@peter-dambier.de</a>></span> wrote:<br>

<br>
did you reboot or start/stop bind or kill?<br>
<br>
I remember having a named process dangling that kept me from<br>
receiving. After rebooting that worked again.<br>
<br>
with<br>
<br>
ps -elf | grep named<br>
<br>
you should see your named and how it was called:<br>
<br>
ps -elf | grep named<br>
<br>
5 S hammer 4142 1 0 80 0 - 4142 - May26 ? 00:00:05 named -u hammer -c named.conf<br>
<br>
Now kill 4142, that is my named. Start named manually:<br>
<br>
named -u hammer -c named.conf -g<br>
<br>
That "-g" switch gets you a named console and you can<br>
see what goes wrong even if it does not write a log.<br>
<br>
"Control c" terminates bind and you can either start it without "-g" or<br>
whatever way you normally do.<br>
<br>
<br>
Kind Regards<br>
Peter<br>
