NFS Sharing and write issues

Hey there

I tried to find something similar to my issue on the forum but seems like
no "ad-hoc" solution has been replied to other similar threads.
Anyway...
I have a desktop running Slackware 12.0 with default kernel. I have a partition used for downloads and storage mounted with these options (taken from /etc/fstab):

Code:

/dev/hda3        /extra           vfat        auto,user,rw     1   0

Now, since I have a laptop with just 15GB's of space running PCLinuxOS 2007, I've setup an NFS share on my desktop so that I could save files downloaded and created on the laptop.
To achieve this I edited /etc/exports and made it look like this:
(from /etc/exports on my desktop)

Code:

/extra/ annihilator(async,no_subtree_check,rw)

Where "annihilator" is my laptop. When I mount that folder on the desktop and then I mount it on the laptop (using the nfs filesystem) i can see my files but cannot write to the share. I have the same username on both PC's but they have different UID's (1000 on Slackware and 501 on PCLOS2007). Permissions on the /extra folder are set like this:

Code:

root@skatola:/# ls -la /extra/
total 32
drwxr-xr-x  8 thug users 4096 1970-01-01 00:00 .
drwxr-xr-x 20 root root  4096 2007-08-02 21:47 ..
drwxr-xr-x  7 thug users 4096 2007-07-22 19:06 Backup - 22-7-2007
drwxr-xr-x  5 thug users 4096 2007-06-02 18:58 Games
drwxr-xr-x 15 thug users 4096 2007-08-26 01:03 Movies
drwxr-xr-x 11 thug users 4096 2007-06-17 17:59 Music
drwxr-xr-x  3 thug users 4096 2007-05-17 20:45 School
drwxr-xr-x  3 thug users 4096 2007-05-29 13:57 Software

Any hint or idea on how to make that share writable?
Thanks in advance

UID's and GID's need to be the same on both machines. The machines don't care that you have the same name. I know tons of different "john" and "mike", but they aren't the same person.

Else, you can chmod -R 777 /extra, but that's a security issue (if you care about that). Also, root (by default?) cannot write to NFS mount points, only the root hosting NFS can.

Thanks for your reply!
I changed my UID so that it match the owner of the folder on the NFS server and everything is working flawlessly.
Cheers
