In addition, ping only deals with the network latency issue, and not very well at that -- it's only an instantaneous measure. Since cvsup sessions tend to last relatively long periods of time, even if you were to look at just latency, you would want something that would look at minimum, maximum, standard deviation, and median latency over similar relatively long periods of time. Of course, there are also host loading and bandwidth issues, network congestion & drops problems, network route flapping issues, and a whole host of other things that you'd also want to look at. As I said before, I don't think any one simple solution to this problem will do the job. -- These are my opinions and should not be taken as official Skynet policy _________________________________________________________________________ |o| Brad Knowles, <blk@skynet.be> Belgacom Skynet NV/SA |o| |o| Systems Architect, Mail/News/FTP/Proxy Admin Rue Col.
