Zenoss, VMWare and Critical “is up” alerts

I’m currently working on setting up Zenoss to either replace or supplement our current network/server monitoring systems.
As its in test, it got stuck on our currently relatively unused “old” vmware environment (ESX 3). After initially going well it start to go wrong. We kept getting critical alerts that a server was up. [...]

Exim: Deliver some email address on local domain remotely

Most of my email is handled by a server I run, except for a few legacy address I can’t really move for now.  Before I had been lazy and send simply relayed all mail that didn’t have a local mailbox onto the second server.  However I was forwarding shed loads of emails to duff address. [...]

inputlirc

Just found a package for a bit of software in ubuntu called inputlirc.
Ubuntu lists it as:
Zeroconf LIRC daemon using input event devices
This is a small LIRC-compatible daemon that reads from /dev/input/eventX
devices and sends the received keycodes to connecting LIRC clients. Inputlircd
needs no configuration, it uses the standardised names for the keycodes as
used by the kernel. [...]

Yet Another Cacti Update

Well I’ve now got cacti pretty much sorted. Its finally running on a server with enough disk i/o to cope (it still > 3 years old, but at least it works). Its also now become important enough to be moved onto a server with support as some point. Once we’ve vitalised our [...]

HOWTO: NUT & CPU Throttling/Frequency Scaling

After a couple of power cuts lasting long enough for my UPS to shutdown my PC, I’ve been meaning to get NUTs to set my CPU to lowest speed possible when running on battery power, this week I finally got round to it. Please note these instructions are based on Debian 4.0 (Etch) [...]

WUFTP Rule for fail2ban

I’ve put to gather a rule for wuftp for fail2ban v0.6 (ie the version in backports for sarge – http://backports.org/). The regexp is straight from the version available in debian unstable. Seems to do the trick.
[WUFTPD]
# Option: enabled

GVIM/Ubuntu/Debian Syntax Highlighting

It appears in the Edgy Eft and Debian Etch that Syntax highlighting in gvim has been switched off by default.
To add it back add the following line to /etc/vim/gvimrc

” Also switch on highlighting the last used search pattern.
if has(“syntax”) && (&t_Co > 2 || has(“gui_running”))
syntax on
set hlsearch
endif

Ubuntu + Printing (lp etc)

It appears when when I created the first printer in ubuntu it didn’t set it as default and hence nothing that used the likes of lp would print.
Easy to fix – log on. Goto system > administration and set a default printer. Still you’d have though that when I only have one printer, [...]

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 ieee80211 module and the [...]

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.
