Upgrading from 10.04 to 12.04: Post upgrade experiences…

“Where is the love…” So you finally did it: You upgraded from Ubuntu Server 10.04.x LTS to 12.04.x LTS and things went well, but after the reboot you’re having a few problems – you’re not alone! There’s probably an infinite array of server configurations out there, so the notes presented here will hopefully provide some… Read more »

Upgrading DAViCal to support iOS7 devices

Are we speaking the same language? In a previous post, I went through how to build a calendar sever using DAViCal – created by fellow kiwi Andrew McMillan. The server has run perfectly since the day I built it, and it was only recently (read: last year) that I noticed I was no longer getting… Read more »

Updating the package version of ClamAV on Ubuntu.

The freshest clams Anti-virus programs are great… provided you keep them up to date! Sometimes keeping them up to date can be tricky if they are prepackaged from a repository – you have to wait until someone packages the updated version. This isn’t ideal, as I discovered one day after checking my ClamAV freshclam.log I… Read more »

Adding support for Active Directory to BIND9 DNS.

Taking DNS a step further Back in September 2010 I posted an article on creating your own DNS server (using BIND9) and linked to DHCP. There was probably one element of that setup that was missing – Microsoft’s Active Directory. Active Directory uses DNS as its domain controller location mechanism and leverages the namespace design… Read more »

Online resizing of an LVM partition.

The concept and objective I built a Bacula server a while back with a 500GB HDD, which I use to backup a number of servers including a mail server. I had it setup so it would recycle the volumes every 180 days (roughly six months), thinking that each volume would well and truly be ready… Read more »

Building a XMPP (Jabber) server.

Setting up an XMPP server “XMPP by any other name would…” We recently had a chat (pun not intended) amongst the team to discuss some of the ways we could cut costs during these financially challenged times. One area identified was around inter-office calling charges. We have three stores: one in Onehunga (local), one in… Read more »

Creating your own calendar server.

“I love my little calendar girl” Ever since I first put together my own e-mail server, I’ve been looking for something to “round-out” the offering with centralised calendar functionality using the CalDAV protocol – my own “Groupware” solution so to speak! The criteria was fairly simple: I wanted it to serve of the Linux platform… Read more »

Monitoring host availability using Nagios.

I just want it to work! It was with a due sense of urgency that I stumbled into my Christmas break this year, like a marathon runner barely making it over the finish line. Oh, I thought I was prepared, I had my remote access after all… what else would I need? Two days in,… Read more »

Using Bacula to archive data.

I hate tape! Ever since those early days working as an operator, my least favourite job was changing the daily backup tape. Oh sure, if your company has loads of cash you could shell out for an autochanger, but none of the organisations I worked for were ever prepared to pony up the dosh for… Read more »

Using CUPS to share printers across your network.

Motivation Most things in my house are networked so it was with some disappointment that we had to replace a laser printer at home but couldn’t afford one with a network card in it. Keeping the printer in the garage away from “sticky fingers” meant that having it connected to the network was imperitive. I… Read more »
