Is socks5h supported?

[Klaaktu]

Hi. Is socks5h(remote DNS resolution) supported? I see that there are commits about DNS relay, but README only mentions socks5.
I have set socks5h as global proxy in Ubuntu, but often websites wait for some time before loading, as if host names are being resolved locally (or because of something else, I'm not sure). Also apt only supports socks5h.

It depends on your client's configuration. All socks5 proxies supports remote domain name resolution.

Some applications don't recognize socks5h and simply treat it as an HTTP proxy, which can cause issues. For example, if you only set ALL_PROXY=socks5h://localhost:1080/, Git LFS will treat it as an HTTP proxy. But if you only set ALL_PROXY=socks://localhost:1080/, cURL will use your local resolver, which may not be desirable in your network environment.

In practice, you can set it this way:

• ALL_PROXY=socks://localhost:1080/
• HTTP_PROXY=http://localhost:8080/
• HTTPS_PROXY=http://localhost:8080/

Most applications (Git LFS, cURL, etc) will use the HTTP proxy and work correctly. Applications that support ALL_PROXY will recognize socks and most likely send requests directly without your local resolver getting involved.

I see. Thanks for the answers guys.

p.s. It seems Ubuntu network settings gui doesn't support specifying scheme. I set socks5h://127.0.0.1:1080/ in the socks field and this is what the environment variable looks like:

$ echo $all_proxy
socks://socks5h://127.0.0.1:1080/

If you are looking for a way to set proxy with environemnt variables, why not using HTTP mode?

Yep I have both HTTP and Socks now:

$ echo $http_proxy
http://127.0.0.1:8388/
$ echo $all_proxy
socks://127.0.0.1:1080/
