Sockets are the public endpoint that border0 creates on behalf of users. Each socket will come with a unique DNS name. The following types are supported:

1. HTTP: Use this when your local service is a http service.
2. SSH. Used for handling ssh connections to remote or local systems .
3. Database. Use when working with mysql, mssql or postgres type databases.
4. TLS. Use this when your local service is a non-http service.
   In this case the platform will proxy a encrypted tcp session. This is used for example for ssh or https services.
   Note that in this case border0 will, in addition to a unique DNS name, also create a TCP port number just for your
   service.
5. RDP: Used for Remote Desktop services.
6. VNC: Used for VNC services.
7. VPN: Used for VPN services.

Connecting your fist test socket

border0 socket connect my-http-socket --httpserver

--httpserver

Probably the fastest way to get full end to end connectivity through a socket is to use a built in HTTP server

$ border0 socket connect  my-http-socket --httpserver

Connecting to Server: tunnel.border0.com
