Hi Bob.

Here is what I have found so far.

I was able to mount kata / and /home about 1/2 hour ago.
I used the mount to make a comparison between 2 files on kata.

However, the next thing I tried to do (an ls I think)
the connection hung up.  Every time I attempt to cd to the mount,
konsole locks up and I have to quit the session.

In /var/log/syslog and messages I have repeated instances of:

Dec  5 15:58:50 arriba kernel: [164159.298317] nfs: server kata not 
responding, still trying

In /var/log/kern.log repeated instances of:
Dec  5 15:58:50 arriba kernel: [164159.298317] nfs: server kata not 
responding, still trying

I have a feeling that I have told nfs to use nfsver=2 and I don't 
actually have nfsver=2.  However, I don't know how to find out
what I do have except for what /proc/filesystems tells me.
And I don't know how to load another version of the nfs system.

I've read a _lot_ of posts of Karmic users complaining that nfs won't 
run.  Some have said it won't run unless you add nfsver=2 to the fstab 
line but it's not working for me.  One person posted that he was able to
change to nfsver=4 and I might try that since it's listed in 
/proc/filesystems but I thing nfs4 needs kerberos to run properly.
I have zero experience with that.

It's kind of a big mess and I'm amazed that the Ubuntu people have not 
jumped on this since nfs is so crucial but I haven't heard a word.

I thought it would be a good idea to load Karmic on this netbook which 
would prepare me for all the UI changes that have been made until the 
LTS version coming in April but apparently not such a good decision.
I have a big meeting Monday with the tax accountant and I don't dare to 
try and load something else coz I'll need the netbook.  I'll probably 
just go to the meeting and turn over any files he wants on a thumb drive.

Here are a couple of urls on the problem:

	Man claims to have a working nfs but I don't understand what he's doing.

	Changing to nfs4 seems very complicated

	Many peoples experiences on mounting nfs in nfs3
	which isn't even on my list.


Thanks for trying to help,
