Hello ! Don't understand your problem quite right. There was a new user appearing, or was it one user of the already signed-in users ??? If a fresh new user appeared just so, your linux-box obviously then is rooted and you can install anything new. For to make your linux-box unrootable (by others), chattr -i <password-files> and chattr -i <shadow-files> as root at least. Instead of install anything new, you maybe could unplug the modem-plugin. A new safe long password. chattr -i then the files. And then you should check your files if they had been changed . . . e.g. with tool chkrootkit available on sourceforge.net or by hand check each file with a microscope . . . If this mail is not the correct answer, then trash it . . . Regards. A Beginner . . . not a guru . . . Am Mittwoch, 23.
