Ok i've got a mandrake 9.1 system that is acting up.
When first installed over a year ago, I set the security level at some annoying level. But I could deal with it.
At some point, the msec links to server settings in /etc/security/msec disappeared.. the link 'server' is broken. I no longer get emails about some daemon checking permissions and various other security checks. This sudden stop was sort of disturbing but its not a production box I wasn't too worried about it.
Yesterday, another user was installing some php bb software.
Today, as a normal user I can no longer execute most of the binaries in /bin or /usr/bin
I get a:
-bash: /usr/bin/uptime: Permission Denied
The permissions for this file seem fine:
ll /usr/bin/uptime
-r-xr-xr-x 1 root root 2876 Mar 3 2003 /usr/bin/uptime*
I suspected perhaps the glibc was not accessible or something but the permissions on libraries seem fine also.
I'm about ready to just wipe the system and start over this weekend. The distro is so old even MandrakeUpdate will no longer update rpms because the ftp server is out of date or something.
I'm mainly just curious how this is possible. I consider myself pretty experienced with linux and security in general, but this mandrake security stuff has me pretty stumped.
Did somebody do something like remount the / and/or /usr filesystems noexec? That might cause this behavior. What happens if you try running uptime as root?
