do not understand this closure

[Joel VanderWerf]

Hey

I can't seem to get this simple DRb client to access the server over my
network... ...
h_server = DRb:RbServer.new 'druby://127.0.0.1:5555',

What about using an eternally visible network interface, in place of
loopback? (Or did you just put that in for the question to a public
list?) Try druby://localhost:5555, for example.

An eternally visible network interface! I can't decide if that's every
sysadmin's dream or nightmare.

Sorry, Joel, no offense meant, but I couldn't resist

I am externally grateful to you for pointing that out
