nfs timeout

[Philip Axer]

Hi,
in my experience nfs (by udp) over long distance doesn't work very well. I 
decided to mount with -o tcp. This switches from lossy udp to the relieable 
tcp. There are some not so good issues to, e.g. if the connection breaks 
down, the accessing process blocks (try to google).
Another hack is to tunnel your data through a vpn tunnel, which does basically 
the same. With the vpn thing I could establish a much better connection for a 
video stream over rtcp, which is based on udp.
