Re: Local DoS : RedHat 6.0

Hello ~jim,

Same  results  are  under FreeBSD 3.2 with XFree86 3.3.3.1 and FreeBSD
4.0  with XFree86 3.3.6, so it seems to be common X(Free86 ?) problem.
Since  X  server can be launched via telnet session it's not necessary
to be console user to crash console this way.

P.S.  no  reaction on Ctrl+Alt+Backspace or Ctrl+Alt+del, no X server,
xdm  or  any  other  X  processes  to kill, but host is alive, you can
startx again via telnet to solve problem.
