I'll email you a copy of that, in case you don't have an easy way to get one. rick ps: This is related to Martin's problem posted recently, as follows: # ls -l /lib/libc.so* -r--r--r-- 1 root wheel 1234432 Jun 15 01:04 /lib/libc.so.7 # ls -l /boot/kernel/kernel -r-xr-xr-x 1 root wheel 12010608 Jun 15 01:38 /boot/kernel/kernel Further info to diagnose the problem: I've got 3 NICs on 35, 135 and 235 (different subnets). Netmasks are: - xx.xx.xx.35/25 - xx.xx.xx.135/26 - xx.xx.xx.235/26 Client is xx.xx.xx.150/26. But you can try it with a single server. A mount on 127.0.0.1 won't work either. Here relevant part of rc.conf: nfs_server_flags="-t -n 4 -h xx.xx.xx.35 -h xx.xx.xx.135" mountd_flags="-l -r -h xx.xx.xx.35 -h xx.xx.xx.135" /etc/exports: /usr/export/src -maproot=root -ro -network xx.xx.xx.128 -mask 255.255.255.192 And here what I changed (rpcbind_flags) and the effects. Notice, I executed rpcinfo each time before restarting nfsd and mountd. Maybe I don't understand the rpcinfo output, because it differs from sockstat. ------------------------------ rpcbind_flags="-h xx.xx.xx.35 -h xx.xx.xx.135" # rpcinfo program version netid address service owner 100000 4 tcp xx.xx.xx.35.0.111 rpcbind superuser 100000 3 tcp xx.xx.xx.35.0.111 rpcbind superuser 100000 2 tcp xx.xx.xx.35.0.111 rpcbind superuser 100000 4 udp xx.xx.xx.35.0.111 rpcbind superuser 100000 3 udp xx.xx.xx.35.0.111 rpcbind superuser 100000 2 udp xx.xx.xx.35.0.111 rpcbind superuser 100000 4 tcp6 ::1.0.111 rpcbind superuser 100000 3 tcp6 ::1.0.111 rpcbind superuser 100000 4 udp6 ::1.0.111 rpcbind superuser 100000 3 udp6 ::1.0.111 rpcbind superuser 100000 4 local /var/run/rpcbind.sock rpcbind superuser 100000 3 local /var/run/rpcbind.sock rpcbind superuser 100000 2 local /var/run/rpcbind.sock rpcbind superuser # sockstat | grep rpcbind root rpcbind 28763 4 udp6 *:* *:* root rpcbind 28763 5 stream /var/run/rpcbind.sock root rpcbind 28763 6 udp6 ::1:111 *:* root rpcbind 28763 7 udp6 *:1008 *:* root rpcbind 28763 8 tcp6 ::1:111 *:* root rpcbind 28763 9 udp4 127.0.0.1:111 *:* root rpcbind 28763 10 udp4 xx.xx.xx.135:111 *:* root rpcbind 28763 11 udp4 xx.xx.xx.35:111 *:* root rpcbind 28763 12 udp4 *:842 *:* root rpcbind 28763 13 tcp4 127.0.0.1:111 *:* root rpcbind 28763 14 tcp4 xx.xx.xx.135:111 *:* root rpcbind 28763 15 tcp4 xx.xx.xx.35:111 *:* client# mount_nfs -o ro,tcp,intr,soft,bg,nfsv3 xx.xx.xx.35:/usr/export/src /usr/src [tcp] xx.xx.xx.35:/usr/export/src: RPCPROG_NFS: RPC: Port mapper failure -
