Knock Client: Incomplete knock sequence with hostname on OS X

[ada-lambrecht]

When using the Knock Client on OS X and a hostname the client seems to only send the first port in the sequence. OS X Version: 10.10.5 Knock Client Version: 0.7

Testing method:

• watching logs on server while sending knock from command line client
• behaves as expected when using an IP address as target
• when a hostname is set instead only the first port in the sequence registers on the server
  • Stage 1 shows in logs then nothing else
• ran knock from client with verbose flag and all ports in sequence are shown
• original installation was from homebrew
• Though it might be port related or number or ports
  • no change with different ports or number or ports
• replicated behavior with OS X client download from http://www.zeroflux.org/projects/knock/
• tested from a ubuntu 14.04 server, behaves as expected
• tested from a OS X 10.9 machine, behaves as expected

Resolution: I was able to get it working by compiling the client from source. Edit: Actually it only seems to work when I use the -v flag

Not really sure why this worked, the homebrew formula pulls the source from zeroflux.org and compiles from source. Homebrew/homebrew@c8cacdda1ac7a46eee0fd677e2983a85ee2e47ec

From looking at that commit it seems to be the same as the compile instructions.
