tech notes

If you happen to use Nortel’s Alteon load balancers and need something to help you visualise your configuration here’s a script that produces graphs of connections and dependencies between groups, virtual IPs, real IPs and services in the Alteon configuration. It’s not very useful, the code is ugly, but the graphs are cool to look at Especially for huge config files with lots of services and VIPs. The script uses two great python libraries – pygraph and graphviz.
