Error running raccoon

[securitybites]

When running a scan I get the following output:

[#] Done enumerating Subdomains

### Raccoon scan finished ###

Task exception was never retrieved

This is on OSX. I installed using pip3.

That's because there is no native 'timeout' command in OSX.
In tls.py you can find this:

#OpenSSL likes to hang, Linux timeout to the rescue
self._base_script = "timeout 10 openssl s_client -connect {}:{} ".format(self.target, self.port)

And that's why raccoon throws the exception. Maybe the bug is due to OSX replacing openssl with native libraries.

The workaround for this is installing 'coreutils' with brew, this will install 'gtimeout' the needed command. Replace 'timeout' with 'gtimeout' and you are to go.

Check this stack overflow answer for more info on gtimeout: https://stackoverflow.com/a/21118126

Edit: I will later in the day for a fix to make cross platform that snippet, we need to detect what kind of OS we are on and pass the correct command.

@securitybites, @PurpleSec
A fix is up in branch macos-support.
Kindly let me know if you can run successful scans now and if so, I'll merge this to master.

[jcmoney]

@evyatarmeged Confirmed. It works now.

Thanks for the helpful insights guys.
macOS support is now available in master and will be uploaded to PyPi soon.
