I have an NFS share on an OpenBsd server. When I assess the share from my Ubuntu box I don't seem to have all permission eg write. Also copying a file from the NFS share to the Ubuntu machine can take > 1 hour for a 44mb file. Any suggestions?

I exported the share through /etc/exports:

/home/some_user/downloads -alldirs -maproot=some_user -network=192.168.5.0 -mask=255.255.255.0

And mounted the share the following.

sudo mount 192.168.5.60:/home/some_user/downloads ~/test

How did you export your share? How did you mount it? – gnud Feb 16 '11 at 10:36
Oh, OpenBSD exports r/w by default :P Sorry =) Anyway, that means you can't write because of some permission problem. – gnud Feb 16 '11 at 12:22
I am more concerned with the slow speeds. – Thomas Feb 16 '11 at 13:04
What is the speed of network traffic over other protocols (e.g. scp, http)? – pjc50 Feb 16 '11 at 15:58
As fast as one would imagine over a 10/100 network they both perform good. – Thomas Feb 16 '11 at 23:28

To increase the speed use UDP:

sudo mount -o udp 192.168.5.60:/home/some_user/downloads ~/test

Try using mapall=some_user to see if that solves your permission problem.

Increase rsize and wsize on the Ubuntu box (I have put this in /etc/fstab):

server:/dir  /dir  nfs  rw,soft,intr,rsize=8192,wsize=8192  0 0
