moving debian repository from one machine (running etch) to another (running lenny) is not as trivial as i thought it would be.well, it not hard ether, is just that you should do few things before the new machine is happy, up and running. the problem lies in the fact that you're moving from reprepro version 1.3.1+1-1 to version 3.5.2-6:. now that's a proper jump, ain't it ;)once i moved all them

I've installed the newest stable of RRD MA (3.1) on debian etch and I stumble upon few problems:- poller.php in cacti wasn't polling anything nor it gave me any errors in the log file.solution: removed php4-* and install php5. most likely that reinstalling php4 would work as well ;)another suggestion would be not to install cacti from etch repository but to do it manually.- when using psUI i was
