No route to host using showmount on Fedora 12

You can list files in your home directory: "ls -n"
You can use the `id' command: id <username>
You can use `getent passwd <username>' to print out your entry in /etc/passwd.

yeah username is just the "human readable"...it's the uid/gid that counts....

use

Code:

getent passwd username

To get the uid/gid

I used the id command on different systems and verified that the user identifier was not the same.

I know NFS is tricky when it comes to the permissions...you should change the UID on one of the systems to match the other...

Do it on the Linux side since it will probably be easier...

What exactly is involved in changing the user identifier?

You don't want to change UIDs and GUIDs, trust me

I don't know if your OS supports this, but on Mac OS X 10.6 one can add a -mapall option to each export in /etc/exports in order to map the connecting client to a specified user on the host.

For example (in /etc/exports):
/path/to/shared/folder 192.168.1.14 -mapall=john

From "man exports":

Quote:

If a -mapall option is given, all users (including root) will be mapped to that credential in place of their own.

There's also a -maproot option if you only want root to get this behaviour.
