I am trying to document the installation of nfs for Linux From Scratch.
The client works, but the server does not and I'm looking for some
help. If this is the wrong place to ask for help, please redirect me.
For now, I am only trying to get nfs version 3 to work.
# mount -t nfs -o nfsvers=3 lfs6:/home/bdubbs /mnt/test
[ mounts OK ]
# mount -t nfs -o nfsvers=3 localhost:/usr/src /mnt/tmp
# mount.nfs: requested NFS version or transport protocol is not supported
Any pointers are appreciated. Details of the procedures I've used are
below.

linux-3.0.4
libtirpc-0.2.2
rpcbind-0.2.0
nfs-utils-1.2.5
glibc-2.14.1
util-linux-2.20
The build procedures were as follows:
1. Restore nfs/nis headers omitted by glibc-2.14.1
2. Build libtirpc
Remove auth_des.c authdes_prot.c des_crypt.c from Makefile
Comment out authdes_create() in rpc_soc.c
./configure --prefix=/usr --libdir=/lib
3. Build rpcbind
./configure --prefix=/usr --bindir=/sbin
Update /etc/services for rpcbind on port 111
4. Build nfs-utils
LIBS=-lpthread ./configure --prefix=/usr \
--sysconfdir=/etc --disable-nfsv4 --disable-nfsv41 \
--disable-gss
Start rpcbind
Start rpc.mountd
Run rpc.nfsd -p 2049 8
Start rpc.statd

It doesn't explain the error message you're getting, but your exports file
doesn't have an entry for localhost. When I try this I get "mount.nfs:
access denied by server while mounting localhost:/usr/src".
2. Build libtirpc
Remove auth_des.c authdes_prot.c des_crypt.c from Makefile
Comment out authdes_create() in rpc_soc.c
./configure --prefix=/usr --libdir=/lib
This shouldn't be necessary. Instead of working around the problem, it
would be nice if you could figure out why you needed to do this, and if
there is a bug in the configure magic, let us know.
Hi.
It looks to me as if /usr/src is only exported to hosts on the 192.168.0 network and not to hosts on the 127 network. Unless you alias localhost to the host address on the 192.168.0 network, then I don't think that this will work as you desire.

Now I remember. Without the patch, other programs don't link. For
example, rpcbind gives:
gcc -g -O2 -o rpcbind check_bound.o rpcbind.o rpcb_svc_4.o
rpcb_svc_com.o util.o pmap_svc.o rpcb_stat.o rpcb_svc.o security.o
warmstart.o /lib/libtirpc.so -lnsl -lpthread -Wl,--rpath -Wl,/lib
-Wl,--rpath -Wl,/lib
/lib/libtirpc.so: undefined reference to `key_encryptsession_pk'
/lib/libtirpc.so: undefined reference to `getnetname'
/lib/libtirpc.so: undefined reference to `_des_crypt_call'
/lib/libtirpc.so: undefined reference to `getpublickey'
/lib/libtirpc.so: undefined reference to `key_gendes'
This is a glibc-2.14 and later issue.

I got it to work. I did a 'killall -HUP nfsd' and restarted 'rpc.nfsd
-p 2049 8' and nfs showed up in rpcinfo and mount now works.
It must have been a sequence error on my part. Sorry for the noise.

Yes, I thought that might be the problem. The hard part is figuring out
why. I am running 'rpc.nfsd -p 2049 8' and I would think that would do
it, but it's not registering with rpcbind. The actual nfsd daemon is
running in the kernel.
I looked at the nfsd.c source and nfsdfs is mounted in /proc correctly.
The threads seem to be started properly in nfssvc_threads() and there
are no error messages either on the terminal or in syslog.
I'm just not familiar enough with the code to see where nfs is supposed
to register with rpcbind. That's where I'm trying to get help. I
suspect I've done something wrong with the build or configuration, but I
don't see where. Is the kernel nfsd process supposed to register when
it starts?
One other thing. When I try to mount the share from a remote (older)
system, the error message is sightly different: "RPC Error: Program not
registered", but I think that means the same thing as above.

The reason you getting the mounting error to localhost is because there are
no NFS services registered with rpcbind. Note the lack of nfs entires in
your rpcinfo -p output. For the above mount to work you would need at least
the following entry:
100003 3 tcp 2049 nfs
Figure out why that is not happening and you find the problem...
