Managing IP networks for free
Here’s a great tutorial on how you could manage your ip network for free! All you need is a Linux box (surprise surprise) and of course an ip network.
The tutorial discusses some popular tools and scripts to perform these tasks :
- Configuration change measurement: storing the configuration history of your network in a useful way;
- Automatic network configuration audits: self-consistency checks wired to loud alarm bells;
- Automatic generation of DNS records for router interfaces, in the interests of traceroute beautification;
- Automatic generation of graphical maps to help operators visualise live topologies as their networks evolve;
- Gathering data from BGP peers to help in choosing “maximum-prefix” session limits.
