The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Very spotty DNS resolution w/ linux DNS caching server on LAN, long waits for page loads and timeouts

Asked by s_auble in Domain Name Service (DNS)

Tags: dns, linux

Hello,
I'm trying to setup SUSE enterprise 10.0 Server with DNS caching and DHCP for my local network. It is also serving Samba shares and is a domain controller but that's it. Currently no firewall either. I just want the SUSE box to cache and resolve the commonly used lookups and forward the rest to the providers name servers.
This was working fine when there was a win 2k server doing the same thing (and a bunch of other stuff too). I have tried to dup. the configuration in SUSE, but so far DNS performance stinks. Anyway, I have DHCP configured to provide addresses to all clients with our LINUX server as the first DNS server and then the ISP's as alternates. ping to external IPs works, but to external hosts ping is unreliable - sometimes works and sometimes doesn't. When it doesn't the Error is host name not found. I have tried dig and nslookups to external sites too, they have pretty much all come back with delays in the millisec's. It doesn't seem like the local DNS is ever supplying a resolution - I have yet to see it's IP returned as the resolver.
Can someone help me figure out how to get the DNS resolving working right on this LAN? By the way the whole LAN is using a linksys router as gateway to the DSL internet connection. DCHP is turned off on the router. This has not changed since swapping out the w2k server for the suse one. Also, I saw some older posts that disabling ipv6 might fix this or might not. I have not tried this - any opinions? More info: The windows clients are experiencing "page not found" and ping errors intermittently even if their IP's are hard coded and the DNS servers are set to the ISPs forwarders. However the longest ping delay to the ISP forwarders is still under 100 ms.
I've almost no experience configuring DNS servers, so please explain in great detail!
Thanks in advance,
Scotty
