I recently got reminded of Quagga which is an OpenSource router solution supporting RIP/OSPF/BGP/ISIS and can connect quite nicely with Cisco/Juniper routers. Having done a bit of work with BGP on bare metal Cisco/Juniper, I thought it could be fun to try out Quagga. BIG FAT WARNING: This proof of concept does not include any […]
I have toyed with this yesterday and thought I would share the experiment. I wanted to try out the OpenVPN software built-in Cyanogen for my Samsung Galaxy S2, for this I used a Debian on the other side (which uses a public IP). The first step is obviously installing OpenVPN on the server, then configuring […]
I got to work on a pretty cool piece of hardware lately in order to setup a highly redundant FS server. This is on Centos 5.x, you will need to grab the following packages from CentOS+: drbd83, kmod-drbd83, make sure you exactly match your kernel revision, you can grab the RPMS from the official mirror […]
I had posted about dnssec a few months ago but that was using some quite cumbersome method to deploy DNS Security to your DNS. I have since looked at OpenDNSSEC which is a more suitable and easier solution. Here are my steps to make it work on Debian. Big Fat Warning: Test this at your […]
I have been using NGINX for a while and really like it. You run into special cases depending on when you are trying to run any CGI stuff. I wanted to quickly document how to get it running on a Debian system. I will assume you are using /var/www as your web root and you […]
VRRP is a neat way to make your setup redundant the right way and balance over an IP from one machine to another. I have touched on IPVS last week in a simple setup, here is now another way to do a neater more robust setup. If you recall last week’s example, we had a […]
I would like to talk briefly about Graphite. Quite simply put the best graphing tool I have dealt with so far. It uses something similar to RRDtool but in a cleverer way, especially on writing data prior to the current date which i find very handy in some cases. I should state that I have […]
