NFS problems (Debian)
I'm trying to share some directories with NFS among Debian machines. In order to do so, I installed nfs-common and nfs-kernel-server on the server machine. It seemed that starting portmap daemon lasted a long time and I get the following messages in /var/log/messages:

Jan 30 18:18:03 masternode kernel: portmap: server localhost not responding, timed out
Jan 30 18:18:03 masternode kernel: RPC: failed to contact portmap (errno -5).

After that, I edited the /etc/exports file to include the directories to be shared; in particular, I added the following code:

/home 192.168.9.0/24(rw,sync,no_wdelay,subtree_check,root_squash)
/opt 192.168.9.0/24(rw,sync,no_wdelay,subtree_check,root_squash)
/usr/local 192.168.9.0/24(rw,sync,no_wdelay,subtree_check,root_squash)

The next step was to export the directories with exportfs -var. The answer I got is:

exporting 192.168.9.0/24:/usr/local
exporting 192.168.9.0/24:/home
exporting 192.168.9.0/24:/opt

Up to now, nothing really strange. However, when I did showmount -e to see which were the exported directories, I got a timeout whitout any error flag. I also got a timeout when I ran rpcinfo -p.

Everything is properly installed and running in the client (192.168.9.102), but when I try to mount the shared directories, I get the following error:

mount to NFS server '192.168.9.101' failed.
RPC Error: 15 ( Program not registered )
mount to NFS server '192.168.9.101' failed.
RPC Error: 15 ( Program not registered )
mount to NFS server '192.168.9.101' failed.
RPC Error: 15 ( Program not registered )

It seems to me that the problem is in the server.

I spent four entire days trying to fix it and I think that I surfed the entire internet, so I'm really desperate!!! Therefore, any help will be very appreciated!!! Thanks in advance.

P.S.: If I do netstat -tupan I get the following connections running:
Code:
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

 P.S.2: These are the processes runing on the server after the whole described process (obtained with ps -faux)

It would be helpful to me if you could post the routing tables for each of the machines.

This is the one from the server...



Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
localnet        *               255.255.255.0   U     0      0        0 eth1
192.168.9.0     *               255.255.255.0   U     0      0        0 eth0
default         192.168.1.1     0.0.0.0         UG    0      0        0 eth1


... and this the client one:


Code:

Sorry, I should have asked for the output of ifconfig from each box as well....

Thanks.

I assume you have identd running on both the server and the client?

Also, I assume you have this file configured properly?
