I’m currently setting up Puppet at Vquence so that, among other things, we can deploy hosts into Amazon EC2 more easily. To ensure a minimum setup time on a new server I wanted the setup to be as simple as echo ‘DAEMON_OPTS=”-w 120 –fqdn newserver.vquence.com –server puppetmaster.vquence.com” > /etc/default/puppet aptitude install puppet This means that [...]

When you create an instance in EC2 you can send Amazon some user data that is accessible by your instance. At Vquence we use this to send a script that gets executes at boot up. This script contains some openvpn and puppet RSA keys so its approaching about 10k in size. This works without any [...]

So I was tearing my hair out today. I’d installed Ubuntu onto a new Sun X4200 so that I could migrate Bulletproof’s monitoring system to it. (Note you need to use edgy knot-1 for the SAS drives to be supported). Anyway as I was installing packages I was getting speeds like 10kB/s. Normally I would [...]
