Have it set to another IP, and if it can't ping the first one for 2
minutes
or whatever time you fancy, do an ifconfig to take the main machines IP,
and restart
all your services. 

Or even easier echo the new IP to the end of rc.conf and reboot!

Subject: Redundant setup on a budget??


 We are a VERY small outfit, (with limited funds as well) and I 
would like to provide a somewhat fault tolerant setup, can 
anyone offer some advice???

Currently have 1 FreeBSD 4.3 machine providing web, email, and 
secondary DNS services. I have another identical 2 system ready 
@ a moments notice to replace the primary in the event of a 
hardware problem. I tested this out, I can simply dump the last 
good backup on it, and to my surprise everything looks good!

My question is this:
 Given the fact that we have 2 systems available what would the 
easiest way to accomplish an 'automated' rollover of services?? 
 Could the machines be somehow synchronized, similar to the 
PDC/BDC NT model??

I can do this in a Windows NT (YUK!!!!!!) environment, but have 
limited experience with BSD. I am in process of removing our NT 
server!!!!! :) (happy happy joy joy!)

Feel free to offer advice off-list, it would be GREATLY appreciated.

THANK YOU in advance,

-Tony
