There are security holes in any system (any machine) if it is not cared for. FreeBSD seems to have less "built-in" holes than other altenatives. That said : You've almost certainly been hacked ==> isolate your machine from Internet as soon as possible (to get it out of reach of a hacker) ==> back up all the **data** that you have on the machine ==> reformat your disk and reinstall all your software from a **known good** media (obviously not from a backup, as it may have been corrupted) ==> read about computer security (I don't have references, but the FreeBSD www site has a good bibliography) ==> there is also a web page on "FreeBSD hardening" referenced from FreeBSD (search for it with the <search> button on the first page of the site) Hope you will recover TfH > > I am getting concerned about this.
