Yes it doesn't exist in a binary package for OSX so thus it does not exist.

Again: Rather than complain, what can I do to make this a little easier for OS X people?

It's been a while but I believe that's a response from Apache server not ftp.

$ lz5 -bash: lz5: command not found $ brew install lz5 ==> Auto-updated Homebrew! Updated Homebrew from b5a6b4e to 7926114. Error: No available formula with the name "lz5" ==> Searching for similarly named formulae... Error: No similarly named formulae found. ==> Searching taps... Error: No formulae found in taps. So, rather than complain about this, how do I do something to fix it? Can I add lz5 as a tap to Homebrew…

Scanning the IPv4 space. I know there are many different projects that do it. I was thinking about how I would do this today. I believe the first step would be to arrive at all the IPv4 blocks (/22, etc), then do a calculation to arrive at the address of each based on the prefix. Then in an array of threads or so, try to connect(2) to the address on some type of service in a timeout handler. If it succeeds, then cons…

This might be a useful starting point: https://blog.shodan.io/its-still-the-data-stupid/ Shodan crawls for most nosql/ queueing software including mongodb and redistribution.

Related to your related: Nice. Is this research public or commercial?

I'm not the person you replied to but the "we" refers to shodan.io.
