Dear FreeBSD list I am having difficulties establishing NFS filesharing between a FreeBSD 2.2.5 NFS server and a FreeBSD 2.2.6 NFS client host. The server freeb1 is dual homed and has the following /etc/rc.conf configuration entries for NFS. -------------- BEGIN /etc/rc.conf for NFS server ---------------------- nfs_client_enable="YES" # This host is an NFS client (or NO) nfs_client_flags="-n 4" # Flags to nfsiod (if enabled). nfs_server_enable="YES" # This host is an NFS server (or NO). nfs_server_flags="-u -t 4" # Flags to nfsd (if enabled). mountd_flags="-r" # Flags to mountd (if NFS server enabled). nfs_reserved_port_only="NO" # Provide NFS only on secure port (or NO). rpc_lockd_enable="NO" # Run NFS rpc.lockd (*broken!*) if nfs_server. rpc_statd_enable="YES" # Run NFS rpc.statd if nfs_server (or NO). portmap_enable="YES" # Run the portmapper service (or NO). portmap_flags="" # Flags to portmap (if enabled). -------------- END /etc/rc.conf for NFS server --------------------- On one 100 BaseT Ethernet subnet, I can successfully mount the file-system freeb1:/home2 on HP workstation nomad running HP-UX 10.10. This seems to suggest the server side is working OK. The corresponding entry from /etc/exports on freeb1 is /home2 -alldirs -ro freeb2 freeb9 freeb4 nomad luther However on another subnet there is a FreeBSD 2.2.6 NFS client, freeb9. The NFS configuration entries from /etc/rc.conf on Freeb9 are :- -------------- BEGIN /etc/rc.conf for NFS client ---------------------- nfs_client_enable="YES" # This host is an NFS client (or NO). nfs_client_flags="-n 4" # Flags to nfsiod (if enabled). nfs_server_enable="NO" # This host is an NFS server (or NO). nfs_server_flags="-u -t 4" # Flags to nfsd (if enabled). mountd_flags="-r" # Flags to mountd (if NFS server enabled). nfs_reserved_port_only="NO" # Provide NFS only on secure port (or NO). rpc_lockd_enable="YES" # Run NFS rpc.lockd (*broken!*) if nfs_server. rpc_statd_enable="YES" # Run NFS rpc.statd if nfs_server (or NO). portmap_enable="YES" # Run the portmapper service (or NO). portmap_flags="" # Flags to portmap (if enabled). -------------- END /etc/rc.conf for NFS client ---------------------- When I execute a mount command on freeb9, it just seems to hang. I have read the FreeBSD Handbook 16.2 entry on NFS which describes client hang due to using slow Ethernet cards. I am using 100BaseT Intel Ether Express Pro/100+ NICs and also ENI 155 ATM adapters, neither of which seem likely to be likely culprits. Nevertheless I tried the recommendation from 16.5 (as root ) mount -t nfs -o -r=1024 freeb1:/home2 /mnt but this just seemed to hang as did other mount attempts. A system reboot was required to un-hang freeb9. freeb9 can ping freeb1 without a problems. Any suggestions/insights please !
