   4 #
   5 # Startup/shutdown script for tor. This is a wrapper around torctl;
   6 # torctl does the actual work in a relatively system-independent, or at least
   7 # distribution-independent, way, and this script deals with fitting the
   8 # whole thing into the conventions of the particular system at hand.
   9 # This particular script is written for Red Hat/Fedora Linux, and may
  10 # also work on Mandrake, but not SuSE.
  11 #
  12 # These next couple of lines "declare" tor for the "chkconfig" program,
  13 # originally from SGI, used on Red Hat/Fedora and probably elsewhere.

  67 Warning: Your system has very few filedescriptors available in total.

  69 Maybe you should try raising that by adding 'fs.file-max=100000' to your
  70 /etc/sysctl.conf file.  Feel free to pick any number that you deem appropriate.
  71 Then run 'sysctl -p'.  See /proc/sys/fs/file-max for the current value, and
  72 file-nr in the same directory for how many of those are used at the moment.
