  • Some statistics from the router at the cabin

    sip0 is a GRE tunnel between the router and the colo box in Seattle, the payload of which is encapsulated as ipsec traffic before being transmitted over the Ubiquity equipment to the switch that the CenturyLink DSL modem attaches to. I don’t get centurylink easter eggs in my search results when I use this interface. […]

  • I’m back on the internet 6 it seems.

  • Back online…

    Sorry for the outage, folks. We’re back up now. This time with a firewall. Ain’t that fun? Someone broke in to the machine in February and was using the un-throttled bandwidth to spam the world. I’ve added a throttle and firewall, much stricter access to the internal network, monitoring tools and an alert infrastructure. Hopefully […]

  • DNS changes

    I’m working on the family’s servers over vacation. I’m moving a bunch of the bandwidth-consuming bits off of the server on the T1. One of the services I’m moving to its own VM is bind9. I figure it should live on its own box that does only DNS-ish stuff. That way I can make sure […]

  • Network Neutrality in a nutshell

    Network Neutrality is a term used to encompas the need for a balanced playing field on the Internet. Proponents for neutrality claim that having a tiered infrastructure will create a hierarchy of “haves” and “have nots.” The perceived problems would be similar to U.S. politics’ main problem: everyone has an equal vote; but those with […]
