Postman / Insomnia with Proxy based on SSH-tunnel

In general, ssh is a powerful tool when it comes to tunneling and (reverse) proxying. All proxy functionalities offered by dynamic port formwarding with -D (or the reverse -R) are limited to SOCKS proxies.

Postman

Postman only supports HTTP proxies. One way to solve this is using https://github.com/oyyd/http-proxy-to-socks.

  • Installation and example usage:
npm install -g http-proxy-to-socks

ssh -N -D 1080 tunnel-host
hpts -s 127.0.0.1:1080 -p 8080
  • Afterwards, configure Postman to use a HTTP(s) proxy in Settings / Proxy / Proxy Server

Insomnia

Insomnia can use SOCKS5 proxies out-of-the-box even though not well documented. Steps to use it:

  • Start tunnel - e.g. ssh -N -D 1080 tunnel-host
  • Configure Insomnia in Preferences / General / HTTP Network Proxy and add socks5 as a protocol, i.e. simply put socks5://localhost:1080 into the HTTP proxy field. That's it!
