Quick Unix/Linux help

I know this belongs in the Programming/Tech Support section, but I need a quick response 😀

Moving accounts from one box to another screws up ownership of files/directories. What's the best way to restore them?

Thanks!

This thread is so ?on topic? it?s ?off topic?.

 

[xcript]

man chown

server 1 contains 10 accounts. their data was backed up and moved to server2. ownership of the data is no screwed up now. how would i move those 10 accounts over to server2 so that the owernship of the data is like server1?

Your UID's don't match between servers. The OS uses the UID to determine ownership, and not the username. Assume on server1 that Bob is UID 501 and Sue is 502. If on server2 Bob is 502 and Sue is 501, then Sue owns Bob's files when you restore to server2!

You can copy the user's from /etc/passwd, /etc/shadow, /etc/group and /etc/gshadow from one server to the other. Man vipw and vigrp for details.

gzip will preserve permissions, but you ALSO need to migrate accounts/groups, as told above

Watch out for duplicate UIDs. They can be a pain in the rear. 😱

Yeah, personally I would probably tar up the user's home directories, then move them to the new box, useradd the users back, then chown -R the directories to the appropriate users.

That's exactly what I usually I do.
