Hi all,
While working as SU I've chmoded my / (root) with 755 by mistake (yea, stupid me). I've stopped the processes when i saw too many lines go by but at that point it was down to the /proc.

Is there a way to tell the system to fix the permissions? What can i do to make my system safe and "right" again?

Thank you

Restore from a backup. You've got one, right? ;]

Yes, but it is old.

Is there any way to have the system check it's own permissions and then set them the way they should be (like during the install?).

I'm running PHP+MySQL+Apache site on this machine. In the worst case i can rebuild it, but i would REALLY rather fix the problem.

Any ideas? Is there a script that could get file permissions from a similarly build machine and then set them for all the files present in both? That would fix almost all permissions and the rest i can do by hand.
Thanks all

Code:
find * / -printf "%m %p\n" > filename
Will give you the xxx octal permisions in the first column and then the full name with path after a space. One file per line. So it should be something like:
Code:
for i in `cat filename`; do chmod ${i}; done
Although I'm not exactly sober right know - better wait for someone else to check that...
