Ubuntu 11.10 on both server and client
nfs: 1:1.2.4-1ubuntu2

I'm setting up nfs at home. I have the same uid and gid on the server and client, but have different user names. I can mount the nfs export on the client and can read and write files. Everything works fine.

However there is something I don't understand. If I ssh into the server and do ls -l I see that the files are owned by my login on the server. If I do ls -l on the same directory from the client instead of seeing my username and group on the client I see a long number (4294967294).

Everything works fine, I would just like to know why I'm not seeing my local user name.

I hit this one a few days ago and it turned out to be a typo in /etc/hosts (I hit , instead of. - try spotting that one quickly) which caused the client to send the wrong hostname when connecting to the server. This caused idmapd to throw a hissy fit and show messed up ownerships like this.

Thanks. I think my /etc/hosts is okay. I've remembered another detail that makes this odd (or perhaps caused the problem). When I first set this up the my user accounts on the server and client not only had different names they also had different uids (1000 on the server and 1010 on the client). This meant that when I mounted the export the files were owned by the user on the client with uid 1000). I therefore changed my uid on the server to match the client using
