Cacti Update

Well that was easy. I’ve just moved two tables to the type Memory/Heap and cacti runs like it used to (in fact a hell of a lot better than it has been doing recently.) The two tables moved are: snmp_counter64* and poller_output. Both these tables can afford to loose the data on restart – they […]

WPA/IPW2200/Linux/Debian 3

After hearing about Network Manager on LugRadio at Guadec I decided to give it a go. A bit of messing around – including installing the version from Testing I found out I need a new kernel for WPA. Of I went and got 2.6.17 and compiled it. Things of Note: I had to use the […]

Just added another plug-in to cacti over the last couple of weeks – weathermap. Basically allows you to draw diagrams of you’re network, and it takes data from the rrd files and displays different coloured arrows show the percentage of the link used. Basically allowing you to see whats going on, on your network and […]

Open Source & The NHS

The NHS as a whole doesn’t seem to use any open source, nor does it look like any will be coming (unless the likes of Java get GPL’ed) However at work we have started to look into Open Source. We currently have an every-growing Cati Install. Cacti is a great bit of software – at […]

Good Wireless News

After a few weeks of use – I can confirm my wireless works well by just starting wp-supplicant. No constant restarting and removing/radding of modules hoping to get a use-able speed. The speed can sometimes be a bit poor – but at least its use-able and doesn’t hinder unless transferring large files.

Wireless on Linux sucks. It seems everytime one little bit in the chain of programs, firmware and drivers changes I lose WPA capabilities. In fact currently Debian, IPW2000 and wpa_supplicent don’t work together, and apparently this happens on a number of other distributions. I have got it working, but I used a custom 2.6.12 Kernel […]
