EADDRINUSE error

EADDRINUSE error (Endpoint Address In Use)

Error: listen EADDRINUSE: address already in use :::1234

When node.js complains that an address is in use, this may happen because the service did not end properly. In order to kill the hanging process, do the following in an Admin PowerShell window:

netstat -ano|findstr "PID :1234"

Add SSH site to Windows Terminal

Source.

You can use a commandline field in your profile configuration to initiate an SSH connection on tab creation.

Step-by-step guide:

  1. Open Settings (Ctrl+,)
  2. Find the "list" array in the "profiles" object
  3. Duplicate a Command Prompt profile ("commandline": "cmd.exe")
  4. Change the commandline value to: ssh me@my-server -p 22 -i ~/.ssh/id_rsa (use your own connection command).
