LINUX

Note: Various distributions and versions of Linux have slightly different commands from the differences in configuration. One of the commands below should work.

• Open up a root terminal window (Ctrl+T in Gnome).
  Type the following command and hit enter:
  /etc/init.d/nscd restart
• You may need to use sudo depending on your installation instead:
  sudo /etc/init.d/nscd restart
• Some distributions support this command:
  sudo /etc/init.d/dns-clean start
• Or support this command:
  sudo service nscd restart
• Some installations may have NSDS located in another directory, like the following example. You may need to locate where it is installed to be able to execute the correct command.
• /etc/rc.d/init.d/nscd restart
  Restart your application (browser or email client).
