Tangentially related: Not too long a while back, I upgraded my old desktop and installed windows 7 on it, and installed Fedora 14 running in VirtualBox (I mostly play games these days on my home desktop, so this arrangement makes the most sense). Since then I've had a lot of issues with DNS lookups timing out. Like many people here, I run my own DNS server on my network. I found that as soon as a host expired from the cache, it was taking several seconds for DNS lookups to complete, and often they would time out completely. I did some investigation from Linux inside the VM, and noticed a few things: - many/most of the sites I was visiting had TTLs of less than 5 minutes (many only one or two minutes). This led to the problem being a frequent one. - traceroute / MTR to various name servers involved looked fine; there was no significant packet loss or latency. - running dig against the site's DNS servers revealed no problems; the servers were invariably very responsive Finally, I ran dig without specifying a name server, and found the problem (a case of premature optimization, to be sure -- if I'd tested the simple/normal case first, I'd have found the problem right away). The machine was requesting both A and AAAA records; the A records resolved essentially instantaneously, but the IPv6 records were taking over 2s to resolve. Solution: disable IPv6 in Windows. DNS resolution returned to normal. I still do get occasional timeouts when hosts' entries in my name server's cache expire, but these are more rare; and in those cases, clearly there is some delay in resolution that's outside my home network. I can live with that. -- Derek D. Martin http://www.pizzashack.org/ GPG Key ID: 0xDFBEAD02 -=-=-=-=- This message is posted from an invalid address.
