Do I have to chmod 777 my NFS folder when I share?

Question

Under Redhat, if I export a folder as an NFS mount, does the folder have to have RW for users/groups/others? Right now /storage/software is -rwxr-xr-x root/root

i.e. /etc/exportfs

/storage/software *(rw,sync)

On my client, I can mount but I can't write. I'm using a regular user and NOT root. I think "no_root_squash" fixes it but I really don't want that. Then again, nor do I want to have to chmod 777 the folder on the server.

Solution 1

NFS uses the filesystem permissions across systems.

A reasonable solution would to use a group that all users were members of and set the SGID bit on the directory as well. Public writable is for /tmp. If you must, at least set the sticky bit.

Solution 2

You should have the same user IDs and group IDs on both servers. At least those that will use the NFS folder.

then it looks like I'll have to chmod 777 the folder then. It's just a folder for the developers to store all their files.

Not gonna happen. My users can mount from their workstations or from servers.

@luckytaxi: This is why planning network security is so important. I highly recommend conisdering retooling your network before the company grows more, and the problems become much worse. I do understand what this is asking; but it's pain now, or more later.
