Ubuntu DNS timeout issues

[vancheese]

Hi people

 

I've been seeing that running the latest provided linux binary (x86_64 and i386) cause a dramatic DNS slowdown and make the system(13.04 and 13.10) unusable, ala http://forum.bittorrent.com/topic/20498-causing-dns-timeouts/.  Stopping the service immediately cures the problems. Does anyone have any suggestions for the problem and can changing settings (relay server, DHT, Tracker server) make a difference to this?

I know I might be repeating a post or two but  can't seem to search the forum to see if others have similar problems and solutions as DNS is only 3 letters long and the forum rejects the search.

 

Thanks

 

Andy

hello,

 

i can see that issue on my rpi with raspbian and btsync via http://forum.bittorrent.com/topic/18974-debian-and-ubuntu-server-packages-for-bittorrent-sync/

the dns-resolution dropped after minutes of operation and it doesn't matter if i add the nameserver manualy to the configuration of my rpi

with which version do you have that issue?

Any word on a solution to this?  I'm running btsync on an Ubuntu 12.04 box and if it's uploading data it really slams DNS lookups for my whole network.

@jtholb,

 

I suggest you tried the latest version of BTSync? 1.3 has a dramatic improvement: it uses TCP connection to transfer data, while DNS still based on UDP (this is actually the only point I see where they can intersect).
