NFS died

[dravenloft]

I'm using the knoppix 5.01 hdinstall, and trying to use nfs.

nfs-common is 1.0.8-7
nfs-user-server 2.2beta47-22

I couldn't use nfs-kernel-server 1.0.8-7 because trying to install it led to:

Setting up nfs-kernel-server (1.0.8-7) ...
Installing new version of config file /etc/init.d/nfs-kernel-server ...
Exporting directories for NFS kernel daemon...exportfs: No host name given with /Music (ro), suggest *(ro) to avoid warning
done.
Starting NFS kernel daemon: nfsdinvoke-rc.d: initscript nfs-kernel-server, action "start" failed.
dpkg: error processing nfs-kernel-server (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 nfs-kernel-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:
Setting up nfs-kernel-server (1.0.8-7) ...
Exporting directories for NFS kernel daemon...exportfs: No host name given with /Music (ro), suggest *(ro) to avoid warning
done.

 nfs-kernel-server

starting the nfs-user-server causes:

Starting NFS servers:Cannot register service: RPC: Unable to receive; errno = Connection refused

What gives? I've even tried using the maintainer's /etc/export thinking it was some issue with the single entry in mine. No luck.

I think this is the key to the problem:

No host name given with /Music (ro), suggest *(ro) to avoid warning

The format of the /etc/exports file is very particular. You have to either itemize every host that is allowed to connect, or use a suitable range. The error message itself is suggesting that the line with /Music use an asterisk like this:

/Music  *(ro)

Adding * just made that particular error go away. the rest still happen.
