Cable modem up and firewalled. NTL still confused by the fact that we didn't need to rent or buy a cable-modem from them, managed to print out internal notes to their own staff on the invoice for the connection "[name-deleted]-upsell" ;-) (This after housemate had had to explain no less than 5 times last week "no, we don't want to rent/buy cable-modem. Yes, that /is/ because we've got one already. Yes, we are sure it will work. Yes, we can install it ourselves. Why - the household comprises two Unix consultants/network engineers". Didn't stop NTL sending us a useless USB cable-modem anyway. Took 15 minutes for housemate to persuade them that they might want to take it back. He's still not convinced they'll ever get round to doing so, since script being followed by random phone operative clearly didn't cater for people who wanted to return unnecessary kit
Took opportunity to re-read Rusty's unreliable packet-filtering guides.
Much FIPR/CDR stuff todo tonight. Excellent stir-fry cooked by housemate for lunch.
Oh, for those in the UK reading this - steer well clear of all services related to Lloyds-TSB. Customer service non-existent, no-one I've spoken to or received letters from recently has had any authority to do anything the Lloyds computers don't allow them to. Needless to say, substantial evidence now exists that the computer systems are themselves hideously broken. Just don't go there, and if you're there already, get out soon.
