we have CENTOS 5.2 on DELL server. we need allow a user can "su" to another user without password. for example: account user1 can "su - user2" without password. (user2 is NOT root) I know this is big security risk but .... Anyone know how to do it? Thanks.
Check out the sudo command. You can alter the /etc/sudoers file to specify that the "source" user can only run a command as a specified "runas" user. The syntax would look something like:
sourceuser ALL = ( runasuser ) commandLet's say you wanted the user "bob" to be able to run the "grep" command as user "fred". The following line could be added to the /etc/sudoers file:
bob ALL = ( fred ) /bin/grep "bob" would use the sudo command to execute the grep command: sudo -u fred /bin/grep 'stuff' logfileThis is a simplistic example, check the man pages for "sudo" and "sudoers" for more information.
