nfs questions

Hello guys, I've been studying nfs.

I'm a bit confused now because of user home directory mapping.

if the server exports [/home client(rw)] in the /etc/exports

the UIDs and names of server and client should be the same? 

and I was curious if a client-side has a conf file with server:/home/&, can client see every user's data in the server side?

 

*Lastly, I would like to ask if it's okay using /auto.misc file (indirect autofs) as it is easier way than direct autofs

"""if the server exports [/home client(rw)] in the /etc/exports , the UIDs and names of server and client should be the same?"""

It depends. In older implementations of NFSv3 not using idmapd daemon, then yes. UID/GID reservations across different systems had to be the same. If you are using idmapd daemon, then no. The symbolic name is used and different uids/gids can be used on the server and clients.

 

"""and I was curious if a client-side has a conf file with server:/home/&, can client see every user's data in the server side?"""

It depends if you are using root_squash (default), or no_root_squash file options. At any rathe, for NFS you should trust your client admins, as they can see anything being shared to them.
