Root-NFS: Server returned error -13

Hi all,

I'm trying to boot from NFS but I can't access the directory.
The NFS server is torreta (158.42.50.79)
The client is stk823L (158.42.50.66)

Here is the error message:
....
Looking up port of RPC 100003/2 on 158.42.50.79
Looking up port of RPC 100005/2 on 158.42.50.79
Root-NFS: Server returned error -13 while mounting
/tftpboot/158.42.50.66
VFS: Unable to mount root fs via NFS, trying floppy
....

The server shows the following /var/log/messages:
....
torreta mountd[20966]: NFS mount of /tftpboot/158.42.50.66 attempted

torreta mountd[20966]: Blocked attempt of 158.42.50.66 to mount
/tftpboot/158.42.50.66
....

The /etc/exports looks like:
....
/home/ddandres/export 158.42.50.66(rw,no_root_squash)
....

The /etc/hosts is:
127.0.0.1	localhost
158.42.50.79	torreta.disca.upv.es	torreta
158.42.50.66	stk823l.disca.upv.es	stk823L

The "rpcinfo -p" command sais:

    100021    3   tcp   1579  nlockmgr

Can anyone guess which is the problem?

/etc/exports obviously doesn't allow 158.42.50.66 to access
/tftpboot/158.42.50.66

If you notice the kernel is attempting to mount "/tftpboot/158.42.50.66"
while you have "/home/ddandres/export" as your only export.

What you need to do is set a symbolic link from /tftpboot/158.42.50.66
to /home/ddandres/export.  (Depending on the nfs server that might be
enough..  if not you will need to add "/tftpboot/158.42.50.66" to your
/etc/exports file..
