ipmi / linux / dell poweredge SC1435

We recently bought two Dell SC1435 servers off eBay. They seemed cheap and quite well specced (dual 4 core CPUs, plenty of RAM for us) – perhaps ideal for redundant mail servers.

Anyway, they’re IPMI 2.0 compliant – meaning they should be controllable remotely (e.g serial console, forceful power cycling etc without the need for some sort of graphical KVM console or DRAC card.).

spam (policyd-weight + excommunicado)

1. See http://github.com/palepurple/policyd-weight – I’m trying to make some changes to policyd-weight (something I’ve been using for ages) to make it more configurable and add in a GeoIP patch which I’ve seen floating around.

2. See https://twitter.com/excommunicado and http://blog.hinterlands.org/2013/11/an-update-on-communicado/ – for a DNS Blacklist you might want to use –  using excommunicado.co.uk as a RHSBL has stopped about 700 spammy emails for me already 🙂

3. See https://github.com/palepurple/policyd-dnsbl-spf-geoip – which should improve on policyd-weight which gave me problems with it’s helo checking etc. It’s easier to configure and hopefully far easier to read the sourcecode  (still perl though ! ).

FTTC limited by wifi….

Compare :
random speedtest result on ethernet

(Speedtest over ethernet)

with

random speedtest result on wifi

(Speedtest over wifi).

Now how do I go about getting Sky to giving me a wifi router box thing that does 802.11n or whatever?
