[x/net] How to proxy udp traffic over a tcp-based socks5?

[saito-mayumi]

What version of Go are you using (go version)?

$ go version
go version go1.14 darwin/amd64

What did you do?

dialer, _ := proxy.SOCKS5("tcp", "localhost:1080", nil, nil)

_, err := dialer.Dial("udp", "8.8.8.8:53")
fmt.Println(err.Error()) // socks connect udp localhost:1080->8.8.8.8:53: network not implemented

What did you expect to see?

err should be nil. I wish that it can relay my udp traffic over my TCP SOSCKS5 proxy.

What did you see instead?

socks connect udp localhost:1080->8.8.8.8:53: network not implemented

Here is the code I found which raised the error. I'm looking forward to ways which are able to approach my goal.

Hi there,

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

For asking questions, see:

• Stack Overflow with questions tagged "go"

• The Go Forum, a web-based forum

• Gophers Slack, use the invite app for access. The #general channel is a good starting point.

• Go Community on Hashnode with questions and posts tagged with "go"

• The golang-nuts mailing list

• IRC channel #go-nuts on Freenode

Please ask the question on one of the above forums.
