I've googled, gotten help in IRC, and gotten help in Gentoo forums. I CANNOT make nfs shares work. I am baffled, and it appears that everyone else, it seems. I'm starting to suspect that since I'm on ~amd64, the package itself or one of its dependencies is broken. You can find all the details here: http://forums.gentoo.org/viewtopic-t-870681.html Summary: My kernel is configured to support NFS3 and 4. Right now, I'm running 2.6.37. I have installed nfs-utils: [ebuild R ] net-fs/nfs-utils-1.2.3-r1 USE="ipv6 kerberos nfsv3 nfsv4 tcpd -caps" 0 kB This is my /etc/exports: /home/millerti 192.168.1.0/24(async,rw,no_subtree_check) /mnt/backup 192.168.1.0/24(rw,no_subtree_check) When I run "/etc/init.d/nfs start", I get this: nfs | * Exporting NFS directories ... [ ok ] | nfs | * Starting NFS mountd ... [ !! ] | nfs | * Starting NFS daemon ... [ ok ] | nfs | * Starting NFS smnotify ... [ ok ] | nfs | * ERROR: nfs failed to start When this happens, there are nfs-related processes running, but I cannot mount anything from anywhere. Always access denied.

False alarm. Something was screwy with the rpc processes. Killing them and then restarting nfs did the trick.
