The way I do it is to switch to single user and back to multi-user. Under Slackware, you'd do "init 1" and log in again. Then, do "init 3." Warning: you'll still be logged in after the init 3. This forces the scripts that run in multi-user to re-run. However, it doesn't take that long to reboot on most systems if you have to. Also, "init q" will reread /etc/inittab. Sending a hangup signal to inetd or sendmail makes them reread their configuration files. With Slackware, the easiest way to do that is something like "killall -1 sendmail" or "killall -1 inetd." Hope this helps. Adam
