I just got a dedicated server (cpanel/whm. redhat 7.3), i installed bind in it.

How reliable is bind as a DNS server, i am very concerned because if bind goes down all my sites would be offline too.

Im using bind-9.2.1-1.7x.2

Do you have any experiences with this issue? Want to know if its or not a stable server and if i should better use my providers DNS instead of mine.

Also, what are the common problems with bind that leads to a crash.

I suppose that if i have the latest, stable version ill be fine right?

I used to have a reseller account with Hostpacket and the dns server went down a lot of times screwing a lot of people. Thats the kind of problems i dont want to have.

Hope i was clear with my question :)

Regards!

BIND is a good piece of software. If you really know how to use it you can setup different backups systems.

BIND per se has got no problems in my experience. And Bind 9.x is quite a good dns server.

All problems come when the server load goes up and the daemons start crashing one after the other. Apache is able to hold together under heavy loads.

WHM has a built in daemon montioring daemon called chksrvrd which doesn't handle named that well.

I have found that while the named daemon itself comes up , the local cache doesnt load and you have to manually reload named.

If you have less than 100 average sites you have nothing to worry.

Another reason named doesnt restart is when the named.conf has syntax errros. Look for duplicate entries in named.conf and look for /var/log/messages [what it says]

yep. bind is pretty stable. which would be the reason it is used on a fair majority of the nameservers on the internet today.

Thanks guys! Thats what i wanted to hear :)

I dont plan to rely a 100% on my own DNS, i think ill be using my providers DNS or third paty DNS in case my servers went down.

I have also read that bind is the first target for hackers, how vulnerable is it? and how can i secure it. Would i be safe by having the latest stable release?

I dont plan to have a lot of websites on my server, but, does bind have problems resolving more than a 100 domains? Does it generates a lot of load to the server?

Thanks for your replies guys! :)
