It's the first time that I write in this Foro. If it is not the correct site, please tell me which is the correct.
I have a SLES 10 as testing machine. It's exposed to Internet. It had several services like SQUID. I'm saying 'had' becose yesterday I could see that It was clean!!
The root's password has changed!
It's as if the machine had been installed from zero!!

I have logged in as root from a shell (put in the boot process (init:/bin/bash)

What's your opinion?

Thanks for your opinions and help.
