networktest

A simple go binary that runs simple network connectivity tests

Command Line Interface

network tester v0.1 - tests network connectivity

  --only=4|6       only test ipv4 or ipv6 connectivity [default both]
  --timeout=int    timeout in seconds [default 3]
  --target=string  runs some testcases against a specific hostname [default "auto"]
                     please be aware that not all hosts support all tests, which may lead to some tests to fail
                     for instance, ping packets may be dropped or the host does not support IPv6
                     specifying this will NOT limit assertions to ONLY this host

  --parallel       runs each test in parallel
  --no-col         do not colourize output

  --help           this help text
  --version        version

Example output
