Full Discussion: owner Permission changed automatically
Operating Systems HP-UX owner Permission changed automatically Post 302596837 by methyl on Wednesday 8th of February 2012 11:37:18 AM

Finally managed to read the .jpg examples.

The issue is with these commands. I've posted them as comments
because we don't want people executing them.
Code:
# bad line 1 # vi /etc/passwd
# bad line 2 # cp -rf /etc/skel/.* /home/selva/
# bad line 3 # chmod -R selva:users /home/selva/.*
# bad line 4 # chown -R selva:users /home/selva/.*

1) NEVER use "vi" on /etc/passwd. If you are expert, use the "vipw" command, but in your case you probably just needed "view".

2) This command is terrifying. Try this to see what I mean:
ls /etc/skel/.*
Compared with:
ls /etc/skel/.??*

3) This command is a syntax error and didn't do anything.

4) This command is terrifying. Try this to see what I mean:
ls /home/selva/.*
Compared with:
ls /home/selva/.??*

The problem is your use of ".*" when you expected it to match filenames starting with a "." . It actually expanded the the parent directory "." in both occasions. Your problem was made so much worse by using recursive (-r/-R) and overwrite (-f) options to commands when there was no point in that context.
It should be possible to use the "ls" commands I posted above to determine which files were copied or changed in error. However because you used the "-f" switch to "cp" be careful about detecting files which were overwritten (if any).
It's such a mess that it may be quicker to go back to backup, but it depends on how many files you had in /home and whether all permissions are easy to fix.

The change of permissions of some files in /usr /var /opt will be because many of the original files in /etc are LINKS and having copied the lot to /home/selva your commands then issue a recursive "chown" on the copies. Scary. I'm surprised that this system is still running, but don't reboot the system without repairing all the permissions of system files.

QED.

check-permissions

check-permissions(1M)					  System Administration Commands				     check-permissions(1M)

NAME

       check-permissions - check permissions on mail rerouting files

SYNOPSIS

       /usr/sbin/check-permissions [login]

DESCRIPTION

       The   check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured
       alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file  that   check-permis-
       sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is
       reported. Otherwise it reports that no unsafe directories were found.

       As to which .forward files are checked, it depends on the arguments included on the command line. If no	argument  is  given,  the  current
       user's home directory is checked for the presence of a  .forward file. If any arguments are given, they are assumed to be valid logins, and
       the home directory of each one is checked.

       If the special argument ALL is given,  the passwd entry in the  /etc/nsswitch.conf file is checked, and all password entries  that  can	be
       obtained through the switch file are checked. In large domains, this can be time-consuming.

OPERANDS

       The following operands are supported:

       login	Where login is a valid user name, checks the home directory for  login.

       ALL	Checks the home directory of  all users.

FILES

       /etc/mail/sendmail.cf	Defines environment for  sendmail

       /etc/mail/aliases	Ascii mail aliases file
