This is exactly the kind of answer I was actually looking for... the whole point of what I was trying to achieve was to make changes, have them recognized, all without bumping users off the system, and all without having to run the hardware through repeated reboots if my changes failed... For more details, what I was curious about trying to do was to add a netmask to the lo0 line in the file to see what affect that would have. But, I wanted the system to read the change without a reboot if possible. Perhaps you might even be able to comment on if this is even possible? I'm actually trying to trouble shoot a new install of samba, but I'm not giving up on trying to cure it myself yet =) Thanks for the help!!! --John At 12:42 PM 9/22/99 -0700, Doug wrote: >On Tue, 21 Sep 1999, John wrote: > >> Welcome to the next of my "it seems like the answer would be so simple" >> questions... >> >> Is there a way to get the system to re-read /etc/rc.conf without a >> shutdown/reboot? > > Given that none of the answers you've had so far really addressed >your question, I'll give it a stab.
