Specify hostname in client mode

[undirectlookable]

I'm using nginx to proxy requests to chisel, there are several benefits if users can change the hostname of server address

• proxy by any hostname you want, without register a domain or change DNS records. Useful when you have lots of chisel backends with one entry server.
• no DNS query (which is clear text) was sent, man-in-the-middle could not get the hostname, it's more secure.

Probable usage:

$ chisel client --hostname mydomain.com https://1.2.3.4 3000

the --hostname parameter will override the default server hostname.

Note that eliminating the DNS query has no security benefit since the hostname is always sent as clear text anyway (either HTTP headers or SNI for HTTPS).

Also, for the other point, I guess that this is a rather unusual use case. I would suggest to either configure custom entries in /etc/hosts or setup a local DNS server like dnsmasq.

Thanks for the reply. My case is really unusual, and I can use different location to proxy to different chisel backend in nginx config. Maybe It's better to keep the tool simple and easy. 🙂

This sounds like a good idea.
What's more, this setup allows to actually hide your chisel endpoints by adding SSL/TLS. 😉

An alternative reason for this feature would be to support Domain-Fronting as a way to evade detection by certain countries (China).
