IP block renumbering day

… it’s only our internal 10.10.10 netblock, but still, a lot of grunt work.

I managed to reconfigure all the switches without locking anyone out (or myself), and MRTG didn’t complain that much. All that remains is to renumber the dev server, and hopefully doing a perl -p -i -e 's/' /etc/* will do the trick.

Then the IT department can appropriate that new Cisco (the one which has about 4 out of 10 ports in use, when a bunch of bimaps on our firewall could do the trick) for ourselves 🙂
