[Mageia-discuss] home network using broadband router

Moving to the client machine and again using MCC to set up "Access NFS
shared drives and directories" you may again be prompted to install
some NFS client stuff and then you should see a disappointingly empty
Just click the Search Servers button on the right of the screen and
wait a wee while. With good luck and a following wind you should see
the address of your server PC appear with a little "expand me" arrow
When you click on that you should see the name of your server's shared
directory/directories. Highlight the one you are setting up and go
through the buttons at the bottom of the screen.
Choose a mount point - for simplicity I let it use the default offered
Done. You will be asked if you want to save the changes to /etc/fstab.
Say yes and the next time you boot it will try to mount this share
again. If your server PC is always up first then that should be OK. If
you're like me then there is no guarantee it will be up. You might
prefer to be able to mount it yourself when you want it. That is what
the Options button will help you sort out.
If all of that has worked then you can restore the personal firewall
on each PC. First on the server, uncheck the Everything option and
make sure the NFS server box is ticked. On the client PC you should be
able just to restore whatever settings you had before.
If you got this far with no show-stopping errors then life will have
just got a little bit brighter.
If something went wrong then shout. I'll check back on Friday evening,
but you may find the answer before that.
