I have been trying to resolve a problem with NFS and FreeBSD and
I have finally come to the point where I have to ask for help. I
believe I have covered all of the obvious bases and I have simply
run of ideas.
I wish to perform an NFS mount. The NFS server in question is
www.caldera.com. This is a public NFS server.
To make a long story short, I have found that RPC operations fail
when performed as root:
struct> su
Password:
# mount -t nfs rim.caldera.com:/OpenLinux-Lite-1.2 /mnt
NFS Portmap: RPC: Port mapper failure - RPC: Timed out
(... the timeout repeats several times, approx. once a minute.)
# rpcinfo -p rim.caldera.com
rpcinfo: can't contact portmapper: RPC: Remote system error - Operation timed out
(... again the timeout repeats and finally dies)
However, the same RPC operation works fine non-root:
# exit
struct> rpcinfo -p rim.caldera.com
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100005 1 udp 2048 mountd
100005 2 udp 2048 mountd
100005 1 tcp 2048 mountd
100005 2 tcp 2048 mountd
100003 2 udp 2049 nfs
100003 2 tcp 2049 nfs
I have configured this host properly: nfs_client_enable,
nfs_server_enable and portmap_enable are all assigned YES in rc.conf.
I have confirmed that mountd, nfsd, mfsiod and portmap are all
running. The kernel is compiled with NFS support. I do not have
a firewall interfering. I am using iijppp with no packet filtering.
When I started this, I was at 2.2.6-RELEASE. After eliminating
all of the above as the source of the problem, I suspected that an
upgrade might help; I am now at RELENG_2_2 and getting the same
behavior. In all other ways, this is a trouble free IP host.
I have several FreeBSD hosts on my private Ethernet. Rpcinfo and
NFS (client and server) work fine on all hosts _within_ my network.
The problem seems to be specific to root processes attempting
non-local RPC communications.
I have confirmed that the NFS server in question does allow public
clients; several people have been able to mount the NFS volume with
Stable systems with no difficulty. In one case, the other person
was also using iijppp.
BTW, Please forgive the Caldera bit :) The truth is, I am more
interested in figuring out why the NFS mount is failing than finding
alternative ways of obtaining Caldera.
Thanks in advance for any direction you may provide.
