Wrong chmod!!
 
Hi everybody,

I'm a little bit in trouble guys!
I was changing permission on a folder to compleate an installation (joomla)
I type in this command:
chown -R -v -f web22_xxxxx:web22 /*
:eek: In this way I changed a lot of files and folder permissions!!
I would like to change only the permission on 1 specific folder (the web folder).
I'm not a linux expert, I'm only trying to do the best of myself...

By the way when I realized that the command was wrong it was to late!!
The command run only for few seconds but now I can't log on my ISPConfig admin console!
I receive this error:
Code:

Warning: include(../lib/config.inc.php) [function.include]: failed to open stream: Permission denied in /home/admispconfig/ispconfig/web/login.php on line 30

Warning: include() [function.include]: Failed opening '../lib/config.inc.php' for inclusion (include_path='.:') in /home/admispconfig/ispconfig/web/login.php on line 30

Warning: require_once(login/lib/lang/.lng) [function.require-once]: failed to open stream: No such file or directory in /home/admispconfig/ispconfig/web/login.php on line 31

Fatal error: require_once() [function.require]: Failed opening required 'login/lib/lang/.lng' (include_path='.:') in /home/admispconfig/ispconfig/web/login.php on line 31

The only modified folders that I can see in the console (putty) are with this path

changed ownership of `/home/admispconfig/ispconfig/web/phpmyadmin/themes/original/img/b_lastpage.png' to web22_xxxxxx:web22


Do you know if exists an easy way to go back??
I really don't know what I can do!

Please help, :( :eek:
Thanks

This effectively started your command from the top level root directory. Everything is now changed. There is almost no way to recover except a complete reinstall. Sorry.

But,
do you know in which way it start to edit the permission?
Starting in alphabetic order or something like that?

I have another server that have the same installation.
Perhaps I can try to change again the permission one by one spotting them on the other server.
The problem is that I need to know where to start... :(

Also can you tell me the right command to edit the permission on one specific folder?

Thanks

You could try setting the owner to root, do know if it would work:rolleyes:

nox171 16th February 2007 12:44

I would try to recover the situation... not destroy everything... Actually i wouldn't like to re-install again!

nox171 16th February 2007 12:50

ok...
looking to the other server I can see the folders where I've changed the permission.

Now I'd like to know the right command to edit permission...

Thanks!!!

chown normally starts with the lowest numbered i-node. See this as a unique identifier. The way i-nodes are numbered differ from system to system, even if you use the same installation/distro.

If you want to compare everything manually, open three ssh sessions, one to your working system (system A), two to your corrupted system (system B). Type
Code:

cd /
ls -al | less

on screen of system A and one screen of system B. Compare each and every line. On the second screen of system B, use
Code:

chown right_user.right_group <full file name>
to set the owner/group correctly.
Do all this as user 'root'. Be prepared to work on this for about two days, depending how much you installed.

Right thanks
I've just started.

I found something like that:
Code:

server1:/bin # chown root:root /bin/*
server1:/bin # ls -la

using this command:
Code:

chown root:root /bin/*
As you can see that folders whit this symbol ->, (are them folders? ) don't change the permission to root...

Do you know why?

martinfst 16th February 2007 13:28

-> indicate a symbolic link, a pointer to the actual file. To change the symbolic link owner/group add the -h flag:
Code:

chown -h root:root /bin/filename
Please stop using the asterix '*'to address files. It will expand to every file in the /bin directory (in this example). Using the * constantly will bring you further and further away from solving this. Use the real and full path name. Example: /usr/bin/vi. Nothing less.
