➜  ~ tcping-fixed.py --help
Usage: tcping-fixed.py [OPTIONS] HOST

Options:
  -p, --port INTEGER      Tcp port
  -c, --count INTEGER     Try connections counts
  -t, --timeout FLOAT     Timeout seconds
  --report / --no-report  Show report to replace statistics
  -4, --ipv4              Use IPv4
  -6, --ipv6              Use IPv6
  --help                  Show this message and exit.

the result is ascii table by using --report.

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.
