Querying an IP restricted API with Postman

Rationale Had an IP to debug, but it is only allowed from server IP addresses.

Unfortunately Postman doesn’t support SOCKS proxy, so have to find something else. No problem.

Start SOCKS proxy

ssh -D 7777 -fCqN -I ~/.ssh/id_rsa my-host

• -D: The bind address.
• -f: Requests ssh to go to background just before command execution.
• -C: Requests compression of all data.
• -q: Quiet mode.
• -N: Do not execute a remote command. This is useful for just forwarding ports.
• -I: Specify the PKCS#11 shared library ssh should use to communicate with a PKCS#11 token providing keys for user authentication.
• ~/ssh/id_rsa: Public key to use
• my-host: Entry in ~/.ssh/config’s Host

Start HTTP to SOCKS proxy

Install:

npm install -g http-proxy-to-socks

Run the proxy:

hpts -s 127.0.0.1:7777 -p 7788

Set up Postman to use the HTTP proxy.

File → Settings → Proxy → Add a Custom Proxy Configuration

Good luck.
