Congratulations to Sumana on her promotion.

oh, that's why

For the past week or so I have been occupied with the difficult question of why Computer A refused to respond to ARP queries from Computer B.

Today, I finally thought to read the routing table on Computer A closely enough to realize what was wrong. Computer A used to have two IP addresses (long story), and the second one has been recycled for Computer B, but the old annotation saying to route packets for B's address via the loopback interface was still there. The loopback interface, naturally, does not reach Computer B.

and once again

why am I still awake?
