I have set "sysctl vfs.usermount=1" on the client, but I get : % mount server:/share ~/mnt [udp] server:/share: RPCPROG_MNT: RPC: Authentication error; why = Client credential too weak on the server, /etc/rc.conf contains : nfs_reserved_port_only="NO" weak_mountd_authentication="YES" rpcbind_enable="YES" nfs_server_enable="YES" mountd_enable="YES" rpcbind_enable="YES" with these flags, mountd should be started with "-n -r", but a debug trace of "sh -x /etc/rc.d/mountd start" gives : .. + checkyesno weak_mountd_authentication + eval _value=$weak_mountd_authentication + _value=YES + debug checkyesno: weak_mountd_authentication is set to YES. + return 0 + mountd_flags=-r -n + rm -f /var/db/mountdtab + umask 022 + + return 0 + _return=0 + [ 0 -ne 0 ] + echo Starting mountd.
