Commands: Troubleshoot Ports
The `consul troubleshoot ports` Helps troubleshoot TCP ports by printing if they are open or closed.

Consul Troubleshoot Upstreams

Command: consul troubleshoot ports

The troubleshoot ports prints TCP port statuses to help you troubleshoot port connectivity.

Usage

Usage: consul troubleshoot ports [options]

Command Options

  • -host=<value> - Host name to troubleshoot TCP ports for. You can also set the CONSUL_HTTP_ADDR environment variable instead of using the -host flag.
  • -ports=<value> - Specifies a comma-separated list of custom ports to check.

Examples

The following example checks the default ports Consul server uses for TCP connectivity. Note that the CONSUL_HTTP_ADDR environment variable is set to localhost. As a result, the -host flag is not required. Refer to Required Ports for additional information.

$ export CONSUL_HTTP_ADDR=localhost
$ consul troubleshoot ports
TCP: Port 8501 on localhost is open.
TCP: Port 8502 on localhost is open.
TCP: Port 8503 on localhost is open.
TCP: Port 8302 on localhost is open.
TCP: Port 8300 on localhost is open.
TCP: Port 8600 on localhost is open.
TCP: Port 8301 on localhost is open.
TCP: Port 8500 on localhost is open.

The following example checks TCP ports status on the hashicorp.com host.

$ consul troubleshoot ports -host hashicorp.com -ports 80,8077
TCP: Port 80 on hashicorp.com is open.
TCP: Port 8077 on hashicorp.com is closed, unreachable, or the connection timed out.
