The supposedly simple solution is to make sure that all users have the same user and group identification numbers (UID & GID) on both sides of the connection. You can, either, ensure that users are created with the same ID numbers, in the first place, or you can change them after the fact. Logout as that user, if you are them. The rest will need to be done as root, and could cause odd behaviour if you change the details of a user that is logged in. You can do a "ls -n /home" to get a quick look at who has what numbers. Edit the /etc/passwd and /etc/group files, so that user and group numbers are the same for the same username and groupname, on one or both sides of the connection. Then "chown -r <username>:<groupname> /home/<username>" (substituting the <variables> for actual names), so that the user continues to own their files (remember, the name is only what you log-on with, ownership is actually done by the numbers). Now, when the user works with files, either side of the NFS connection, they own them. Likewise for any other user. While it may be tempting to squash all users to the same NFS user, and have everything owned anonymously, that will cause problems when a file does need to be owned by the particular user. The alternatives are to learn how user ID mapping works (and that feature wasn't available when I first had to deal with this problem, so I've never gone down that route), or to use another file transfer protocol (than NFS) that makes use of usernames rather than numerical IDs. Having said that, I did try Samba in the dim and distant past, and (apart from being miles slower to send files in one direction), did require you to set up usernames with Samba, for every user that wanted to use it. All in all, it seems easier to ensure that all users have the same ID numbers on all systems that they use and work with. Though I'd hate to have to deal with users who come and go, and use other networks. They'd be hard-pressed to apply this solution to more than one network. -- tim@localhost ~]$ uname -rsvp Linux 3.19.8-100.fc20.i686 #1 SMP Tue May 12 17:42:35 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
