sclient.js

Secure Client for exposing TLS (aka SSL) secured services as plain-text connections locally.

Also ideal for multiplexing a single port with multiple protocols using SNI.

Unwrap a TLS connection

$ sclient whatever.com:443 localhost:3000
> [listening] telebit.cloud:443 <= localhost:3000

Connect via Telnet

$ telnet localhost 3000

Connect via netcat (nc)

$ nc telnet localhost 3000

Install

macOS, Linux, Windows

First download and install the current version of node.js

npm install -g sclient

npx sclient example.com:443 localhost:3000

Usage

sclient <remote> <local> [-k | --insecure]

• remote
  • must have servername (i.e. example.com)
  • port is optional (default is 443)
• local
  • address is optional (default is localhost)
  • must have port (i.e. 3000)

Examples

Bridge between telebit.cloud and local port 3000.

sclient telebit.cloud 3000

Same as above, but more explicit

sclient telebit.cloud:443 localhost:3000

Ignore a bad TLS/SSL/HTTPS certificate and connect anyway.

sclient badtls.telebit.cloud:443 localhost:3000 -k
