caddytest: bind: permission denied

[greenpau]

@sarge , I am running the following config:

https://github.com/greenpau/caddy-auth-forms/blob/a1817048e2311c2e9b8ce5c43fb83433570a753f/plugin_test.go#L12-L26

Configuration file refers to port 3443:

However, I get the following error:

{"level":"error","ts":1588645443.4411454,"logger":"admin.api","msg":"request error","error":"loading config: loading new config: http app module: start: tcp: listening on :80: listen tcp :80: bind: permission denied","status_code":400}

2020/05/04 22:24:03 caddytest: redirecting the dialer from 127.0.0.1:3443 to 127.0.0.1:3443

How to fix the error in the test configuration?

I'll just close this as a discussion (nothing actionable here for the Caddy project at this time, correct me if I'm wrong)

@francislavoie , there is something actionable here ... The config provided to the test instance is not being respected by the test. Previously, it worked.

I think it is the automatic http -> https redirection kicking in.

https://github.com/caddyserver/caddy/blob/master/caddytest/integration/sni_test.go#L15-L17

It automatically binds to port 80.

If you set the http_port to something higher like 9080 this should avoid the binding issues

@sarge , thank you for the pointer! 👍 Adding non-privileged port in http_port worked!
