[zeromq-dev] ZMQ 2.0.6 connect SUB socket error

[Matthew Giedt]

I'm not sure what the problem was on my machine but after fooling the
network interface into thinking that eth0 was a static IP and restarting,
the C_API is now happy to return 0 from getaddrinfo.

Apologies for the run-around.

Regards,
