Start using
1. Download
2. Decompress and install
Unzip < download save path > / ngrok.zip
3. Create an ngrok account and configure authtoken
Because the use of ngrok requires the generation of mapped dynamic domain names, the official website uses the form of users to control and track, so you need to register an account and use it through credentials.
# Keep your credentials $ ./ngrok authtoken <authtoken>
4. Start penetrating the Intranet

NAME:
ngrok - tunnel local ports to public URLs and inspect traffic
DESCRIPTION:
ngrok exposes local networked services behinds NATs and firewalls to the
public internet over a secure tunnel. Share local websites, build/test
webhook consumers and self-host personal services.
Detailed help for each command is available with 'ngrok help <command>'.
Open http://localhost:4040 for ngrok's web interface to inspect traffic.
EXAMPLES:
ngrok http 80 # secure public URL for port 80 web server
ngrok http -subdomain=baz 8080 # port 8080 available at baz.ngrok.io
ngrok http foo.dev:80 # tunnel to host:port instead of localhost
ngrok tcp 22 # tunnel arbitrary TCP traffic to port 22
ngrok tls -hostname=foo.com 443 # TLS traffic for foo.com to port 443
ngrok start foo bar baz # start tunnels from the configuration file
