 Posted: Mon Oct 09, 2006 5:19 am Post subject: all files on my system now owned by root |
 |
|
So I was moving my partitions around, and I wanted to move my system to a new partition. I thought the following would work fine:
| Code: | | cp -r /mnt/oldroot/* /mnt/newroot |
Turns out, I was wrong. All files on my system are now root:root.
I can still log in as a user, but I can't startx unless I'm root. I can't even su to root - gotta log out and in again.
Is there an easy fix for me, or am I looking at a reinstall?
Any ideas appreciated

| If you still have the old partition you could try a combination of find and chown --reference |

well... you could change back the ownership to yourself... start kde (for gnome etc dont know)
go to /home/"username", click on it with the right mouse then choose Properties, second tab is Permissions. on user write your username, group: users, then select Apply changes... and click ok.
have fun, but be warned, that there might be some directories and files, left with root ownership... |

thanks for the ideas - I don't have the original partition anymore though.
I chowned my home directory back, but I still can't su, and startx still fails (trying to move /var/log/Xorg.log to Xorg.0.log)
I suspect there will be quite a number of other problems I haven't encountered yet.. it's not looking good.

chown -R "user" /home/"user" (with maybe chgrp -R "users" thrown there too)
Shouldn't that work? If you've been a good user, you wouldn't have any files outside your home directory, right?

You better check what groups your user is in.

Ugly spot to be in. If all else fails, you could always
emerge -e world
It'll fix all the binary permissions, then you just have to wade through config hell. Configs and directories will probably need to be manually reset but that should fix most of the issues. Any service/daemon related users will probably need their stuff set up again. But the world rebuild and chown ${USER}:users /home/${USER} -R should fix you up right as far as your personal stuff.

Too late for this time, but next time add "-a" to preserve permissions.

The main problem you have is not the file ownership, but the fact you removed the setuid/setgid bits from the permissions. X and su both need to be setuid root to work (X because it needs access to hardware, su because it needs to be able to read /etc/shadow, which can only be read by root).
Try to put the proper permissions again on all those files, and see if it helps:
| Code: | 6228 44 -rws--x--x 1 root root 41352 Jul 2 01:00 /bin/su
6208 36 -rws--x--x 1 root root 35312 Jul 2 01:05 /bin/ping
6111 72 -rws--x--x 1 root root 70984 Jul 2 00:51 /bin/mount
6172 32 -rws--x--x 1 root root 31080 Jul 2 01:05 /bin/ping6
6240 48 -rws--x--x 1 root root 45728 Jul 2 01:00 /bin/passwd
6198 40 -rws--x--x 1 root root 37504 Jul 2 00:51 /bin/umount
20565 48 -r-xr-s--x 1 root man 45792 Jul 2 00:53 /usr/bin/man
205523 1718 -rws--x--x 1 root root 1753632 Jul 22 19:13 /usr/bin/Xorg
16941 36 -rws--x--x 1 root root 34536 Jul 2 01:00 /usr/bin/chfn
16942 36 -rws--x--x 1 root root 33000 Jul 2 01:00 /usr/bin/chsh
241166 12 -rws--x--x 1 root root 11520 Aug 20 13:44 /usr/bin/lppasswd
16943 44 -rws--x--x 1 root root 42480 Jul 2 01:00 /usr/bin/chage
21409 12 -rwxr-s--x 1 root tty 11208 Jul 2 00:51 /usr/bin/write
250284 172 -rwxr-s--x 1 root uucp 172184 Aug 20 14:14 /usr/bin/minicom
20589 24 -rws--x--x 1 root root 22656 Jul 2 01:00 /usr/bin/expiry
20831 28 -rws--x--x 1 root root 25792 Jul 2 01:00 /usr/bin/newgrp
20838 44 -rws--x--x 1 root root 41336 Jul 2 01:00 /usr/bin/gpasswd
7506 20 -r-s--x--x 1 root root 18120 Feb 9 2006 /usr/sbin/unix_chkpwd
7544 16 -rws--x--x 1 root root 14552 Jul 2 01:05 /usr/sbin/traceroute6
214447 16 -rws--x--- 1 root apache 13128 Jul 23 17:44 /usr/sbin/suexec2 |
Those are the files with setuid and/or setgid there are in /bin, /usr/bin, /sbin and /usr/sbin. |

Hey thanks widan - that seems to have fixed it!
I can now use su and startx as a user again!
Hopefully there won't be too many other problems caused by this.. can you think of anything else offhand?
