Welcome to the Linux-HA heartbeat code It works, and it can actually do quite a bit. It can do 2-node IP takeover for an unlimited number of IP interfaces. It heartbeats over: unadorned serial links arranged in a ring topology UDP/IP broadcast heartbeats over ethernet (or similar) UDP/IP multicast heartbeats over ethernet (or similar) special "ping" heartbeats to routers, etc. After installing this package, you'll have to make some HA config files in /etc/ha.d. Samples of these config files are found in the doc directory. These files are named: ha.cf and haresources The beginnings of a Hardware Installation guide can also be found under the doc directory as: HardwareGuide.html or HardwareGuide.txt (take your pick) The beginnings of a Getting Started Guide can also be found under GettingStarted.txt or GettingStarted.html (take your pick) For more info on Linux-HA, I recommend you read the Linux-HA web page. It can be found at: http://linux-ha.org/ The pages found there also document this software and current thinking about plans for the future, etc. Get involved! - Install this software (make install) - Report bugs in it (mailto:alanr@unix.sh) - Enhance it, - Integrate it with other software... - Ask for enhancements...
