Nfs - /etc/exports

[Larry Cotton]

Hi

I'm using fedoracore 2 and am tring to use nfs to export directories
for use on another machine.

My /etc/exports file looks something like:
/home/backups alex (rw,sync,squash_uids=0-99)
/home/servermanager alex (rw, sync)

Whenever I run exportfs I get a couple of warnings to the effect of
'no hostname given with /home/servermanager'.

When I mount the directory on the client I get read access, but not
write access.

Anyone a) know what might be going on here
b) know where I might find some documentation on how to export
directories using nfs.

Cheers
Larry
