Revision:	1.23
Committed:	Mon Feb 24 20:18:46 2003 UTC (21 years, 9 months ago) by tdb

Log Message:	Fairly major commit. This will break the current version of ihost, but this had to be done really to give Pete something to test the new ihost against. The main change here is removal of the TCP Heartbeat functionality from the filter. This meant the following features stopped working :- - Heartbeat testing - Configuration checking - Service checks The heartbeat testing, specifically the monitor, now looks at the presence of UDP packets instead. Before it just looked for the presence of a TCP heartbeat packet, so the change their is fairly negligible. Of course this means heartbeat testing now relies on the UDP working... but I don't see this as a problem. Configuration checking has been repositioned in to the filtermanager. This is a backwards compatible change - the filtermanager should still perform as it should for older hosts. But now there's an extra command to check the configuration is up-to-date, with a similar format to the old TCP protocol in the filter. (although we may optimise this soon) The service checks are broken. This isn't a major issue for us as they were pretty useless in the first place. The concept is good, but the checks are just far too primitive. I expect at some point I'll work on a seperate component that just monitors services, which will replace this function. Further changes in the server include removal of the key checking code, as this relied on a bolt on to the TCP heartbeat protocol to ship the key. This got more akward than originally planned, so I'm happy to drop the idea. In the long term we hope to replace this with a public key systems for signing and even encryption. Finally, general tidy up to remove other bits of code that check for TCP heartbeat packets when they don't need to any more.
