This is how I do this: ** (On server) ~ $ cat /etc/exports /usr/portage *(rw,sync,all_squash,anonuid=250,anongid=250,no_subtree_check) ~ $ id portage uid=250(portage) gid=250(portage) groups=250(portage) ** ** (On client) ~ $ cat /etc/fstab server:/usr/portage /usr/portage nfs tcp,nodev,nosuid 0 0 ** I stripped non-related parts from the above and the "exports" and "fstab" lines should be on a single line. The bit in the exports-file will force all access to "/usr/portage" to be linked to the uid and gid of portage. (Change the values if your portage-user has a different uid and/or gid) I have also opened it to all servers (the * at the beginning of the line) with a firewall limiting access. > (This list is so quiet today I'm wondering if gmane.org is down.) Or simply busy? :) Hope this helps, Joost
