does not respect host argument to forkServer

[zsol]

When I tell it to listen on localhost like here, it still listens on all available interfaces:

tcp        0      0 0.0.0.0:1030            0.0.0.0:*               LISTEN      4222/hlogster 

(output of netstat -tnpl)

I do realize this is probably a bug in Snap, just thought you should know.

Upstream helpfully writes:

The function you're looking for is called setBind (http://hackage.haskell.org/packages/archive/snap-server/0.9.2.4/doc/html/Snap-Http-Server-Config.html#v:setBind) which sets the bind address for the socket. The setHostname function just tells Snap what to use for the local hostname in the event that an HTTP/1.0 request comes in without a Host: header.

@gregorycollins I tried setBind "localhost" and that fails with:

Error on startup: 
getAddrInfo: does not exist (nodename nor servname provided, or not known)
Basic: getAddrInfo: does not exist (nodename nor servname provided, or not known)

setBind is not documented. What does it accept?

[gregorycollins]

IP address or "*".

This makes this a bit more complicated. We could try to do a name lookup in ekg and then pass the IP-address to Snap. I wonder if it's the right place to handle the issue though.

I intend to work around the Snap issue in ekg, as it's important for security to be able to only listen on localhost.
