NFS does work - does not work - does work

[fourhead]

I'm sharing a few dirs between my desktop & notebook via NFS. My FS exports file looks like this (one line of it:

/home/Privat *(rw,sync,no_root_squash)

This works perfectly, but sometimes all of the sudden I get a 'permission denied' on the other machine if I try to mount this share. If I change the above line to say 'itchy' instead of '*' (itchy is the other computer's hostname) then it works again for days or even weeks. Then, all of the sudden, I again get 'permission denied' and the only way to make it work again is to change the 'itchy' back to *???? Why is this? It does not seem to be related to any updates, I'm doing an emerge sync && update world on a weekly basis, and this happens absolutely randomly it seems.

My /etc/hosts on both computers is okay, all other services work fine with the hostname instead of an IP address. Any ideas??

Looks like an NFS server bug, but try the IP address instead of the hostname. As far as I know, it always took multiple lines in /etc/exports to trigger it, so try reducing the number of lines.

Just restarting the NFS server might help immediately.
