TL;DR · WeSearch summary

The article discusses zero-install tunneling as a solution for developers facing restrictions on corporate endpoints. It explains how this method utilizes the native OpenSSH client to expose local applications to the public internet without requiring additional installations. The technique leverages SSH's Remote Port Forwarding feature to bypass common security measures that block traditional tunneling tools.

Key facts

▪Zero-install tunneling allows developers to expose local ports using only the native SSH client.
▪This method is particularly useful in corporate environments where installation of new software is restricted.
▪The technique uses port 443 to bypass firewall restrictions, making it appear as standard HTTPS traffic.
