GFW Fucking.

➜  ~ tcping --help
Usage: tcping [OPTIONS] HOST

Options:
  -p, --port INTEGER      Tcp port
  -c, --count INTEGER     Try connections counts

The return code can be catch by some real-time test tools. Following is an example:

import subprocess as sp

# Print the return code (status=0 mean ping success)
status = sp.call(['tcping', '-c', '1', '-t', '1', 'github.com'], stdout=sp.DEVNULL, stderr=sp.DEVNULL)
print(status)

# OR print the full message
status = sp.run(['tcping', '-c', '1', '-t', '1', 'github.com'], stdout=sp.DEVNULL, stderr=sp.DEVNULL)
print(status)

END

Huh, I just want to check my VPS's network status.
