Actually I did that. Based on the NFS Howto I came up with a set of options, not sure what they mean now, since i set it up quite some time ago... myhost:/mydir /myotherdir nfs user,noexec,dev,suid,rw,rsize=8192,wsize=8192 0 0 Is there some app in debian with which i could easily messure the saturation of my connection? tia, Andreas
