Re: DNS issue

another thing - please stop "nscd" (name service cache daemon ) - in many cases it causes problems.

Re: DNS issue

the same recommendation for "avahi" daemon - disable it.

Re: DNS issue

Hello Vitaly Karasik,

Thanks for your support, It worked halfway.

After stopping of avahi-daemon it is pinging immediatly for the same network but it takes 10 seconds time to ping to other networks.

For exmple,

My name server IP is 10.58.131.246

If I ping some machine in the same network it pings very fast but If I ping some other VLAN for example 10.58.121.xxx then it takes same old 10 seconds time to ping.

I have checked the route, it is alredy there.

Can ypou please help.

Also the reverse lookup is also not working.

weird! did you try to ping by IP and it worked fast?

and regarding reverse lookup - do you see any errors from named into syslog?

Re: DNS issue

Hi ,

There was a problem in reverse lookup.

I have corrected it , It is working fine now.

But what is this avahi-daemon is it required for machine.

Thank you very much for the support on time.

do you mean that it's fixed lookup problem, not ping?

As far as I understand - avahi is useless in static server environment, it should help for client configurations. I haven't investigated this issue in-depth - probably tweaking avahi configuration will help...

you're welcome!
