Bug#404447: NFS problem goes away when using UDP instead of TCP
Hello,
having the same problems with NFS/Samba on the NSLU2 here. Interestingly
enough the only client that was not affected was an Apple iBook when
using NFS, so trying to understand why I found out that Mac OS X is
using NFS via UDP. Switching the other clients to UDP with the mount
option proto=udp helped, no further stalled transfers so far.
BTW, I got the stalls when downloading from the slug, i.e. the NSLU2
sending data, for example when playing media files from the NFS/Samba
shares. netstat -t reported quiet a lot of packets in the sending queue
at those times, sometimes it got the packages out after a while,
sometimes it didn't.
BTW, tcpdump shows a lot of packages with "ethertype Unknown (0xfeb6)"
when trying to trace the problem, but maybe this is unrelated, because
they also show up when tracing SSH packets (with SSH being rock
stable)...
Kind regards
Wolfgang Karall
