 Posted: Sun Aug 20, 2006 7:38 am Post subject: restoring rights and ownerships [solved] |
 |
|
Lately, my hard disk getting a little old, it was more and more generating errors, and it resulted in the filesystem (ext3) switching to read-only more and more frequently, forcing me not only to reboot, but also to do an fsck manually each time  .
So, a little exasperated, I decided to reformat the gentoo partition (I hope it will make things better). I copied all the files to an external disk, formated, and copied the files back to the partition... Only I forgot all the rights and ownerships matters, and did not use the -p option for cp  .
It doesn't seem to be very problematic for the moment: emerge was able to restore the ownerships for portage to run quite normally; I can login as a normal user and do various things without problems. But for example, su does not work, and I had to restore the sticky bit on /bin/ping to be able to ping as user. To restore the normal behaviour and avoid further complications, I think I have to restore the rights and ownerships for the main system files.
Does anybody know how/where I can find the normal values ? Is there a mean to do that in an automated way ? In a word: what is the best solution ?
Thanks.

After some reflexion  , it occured to me that it could have been the same problem. So I put the sticky bit on su too, and mount (also not usable as a normal user). I suppose (hope...) it is the right solution. |

Did you try reemerging shadow?
| Code: | # equery belongs /bin/su
[ Searching for file(s) /bin/su in *... ]
sys-apps/shadow-4.0.15-r2 (/bin/su) |

Thank you for your answer.
I did it and it yields:
| Code: | | -rws--x--x 1 root root 25420 Aug 21 22:27 /bin/su |
which is what I had set. So for su it is OK.
But I am worried about other possible problems that could happen, related to other system files.
Maybe I am worrying for nothing, but I prefer to be sure. |

How would you feel about re-emerging everything?
emerge -eaDv --oneshot world

Thank you for your answer.
I also did it, although I was trying to avoid it since it takes for ever.
However it did not fix everything: for example I was not able to use exim because of bad rights on the log file.
But well I guess I have no other choice than wait and solve the problems as they come  .
I put "solved" in the post title. |
