RE: nfs server issues

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.

ps

Subject: nfs server issues

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.

The packages I'm using:

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
Run exportfs -ra

/etc/exports has:
/usr/src 192.168.0.0/24(rw,async,no_root_squash,subtree_check)

rpcinfo -p gives:
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100000 4 udp 111 portmapper
