Cacti

Thank you white-jeroen! Yes, that was my first suspicion, but it did not help. In the end I found the solution but I still don't understand why this solution solves the problem. The solution I found was to generate the SSH key on machine A both for user a and for user root, then add both these keys ...

Running scripts on remote hosts via SSH is very convenient and I've been doing it a lot in the past weeks since I've found out about it. However recently I've bumped into a very strange problem. Using the method described in this thread I can easily set up a passwordless SSH connection between machi...

I am deeply thankful for your help!

Adding "&unittype=1" to the end of the URL in the existing script does not work, I'm afraid. You need to use my script (attached in my previous post), which uses a different URL and adifferent XML parsing. The basic idea is that I had to hack the php script for it to work with metric u...

Hello!

I've updated the PHP script to work with metric units. I'm not a PHP programmer, so it might be a bit ugly, but it works. To change back to imperial units, just remove the end of the URL: . "&unittype=1".
