help: how to mount a remote unix file system to local fc2 using nfs?

[parv]

i want to mount my own directory on a remote unix server to my fc for read/write.
what shall I do on the unix machine side?
i am non-root in unix system.

i have done the following:
edit /etc/exports:
/home/parv(non-root) IP-of-unix-machine/255.255.254.0(rw)
i stopped portmap, nfslock, and nfs, then restarted in the order: portmap->nfslock->nfs

i did nothing in the unix machine end. finally, i mounted the remote directory:
mount -t nfs IP-of-unix-machine:/home/parv /mnt/remote

there was no error message, but when i enter /mnt/home i found i had only "x" access to
this directory. and i am curious why i was not asked for a password at all.

please give me some suggestions.
