Cannot use socks5 proxy in golang - read: connection reset by peer - http

Question

I have a dockerfile which runs tor -
FROM alpine:edge
RUN apk update && apk add tor
EXPOSE 9050
USER tor
CMD ["/usr/bin/tor"]
and ran it using command - docker run --name tor -p 11000:9050 tor
and checked connection using - telnet 127.0.0.1 11000 and it showed connected
Now I want to use tor as proxy while any request from go program. I tried -
package main
import (
"fmt"
"net/http"
"net/url"
"time"
)
func main() {
proxyUrl, err := url.Parse("socks5://127.0.0.1:11000")
if err != nil {
// TODO handle me
panic(err)
}
cl := http.Client{
Transport: &http.Transport{
Proxy: http.ProxyURL(proxyUrl),
},
Timeout: 18000 * time.Millisecond,
}
resp, err := cl.Get("http://google.com")
if err != nil {
// TODO handle me
panic(err)
}
// TODO work with the response
fmt.Println(resp)
}
But running this program threw error -
panic: Get http://google.com: socks connect tcp 127.0.0.1:11000->google.com:80: read tcp 127.0.0.1:59630->127.0.0.1:11000: read: connection reset by peer
goroutine 1 [running]: <stacktrace>
exit status 2
I tried other approaches also, notably mentioned here and here but kept getting same error - read: connection reset by peer
Please help which part is incorrect here.
Thanks.
--------------------another approach that I tried ----------------
As mentioned in one of the links, I tried this code also -
const (
PROXY_ADDR = "127.0.0.1:11000"
URL = "http://facebookcorewwwi.onion"
)
func main() {
// create a socks5 dialer
dialer, err := proxy.SOCKS5("tcp", PROXY_ADDR, nil, proxy.Direct)
if err != nil {
fmt.Fprintln(os.Stderr, "can't connect to the proxy:", err)
os.Exit(1)
}
dialContext := func(ctx context.Context, network, address string) (net.Conn, error) {
// do anything with ctx
return dialer.Dial(network, address)
}
// setup a http client
httpTransport := &http.Transport{
DialContext: dialContext,
}
httpClient := &http.Client{Transport: httpTransport}
// create a request
req, err := http.NewRequest("GET", URL, nil)
if err != nil {
fmt.Fprintln(os.Stderr, "can't create request:", err)
os.Exit(2)
}
resp, err := httpClient.Do(req)
if err != nil {
fmt.Fprintln(os.Stderr, "cannot make get request: ", err)
os.Exit(2)
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
fmt.Fprintln(os.Stderr, "cannot read response body: ", err)
os.Exit(2)
}
fmt.Println("received response -> ", body)
}
but received error -
cannot make get request: Get http://facebookcorewwwi.onion: socks connect tcp 127.0.0.1:11000->facebookcorewwwi.onion:80: read tcp 127.0.0.1:59826->127.0.0.1:11000: read: connection reset by peer
exit status 2
Any help is appreciable.

Answer 1

After making sure tor is working properly on port 9050.
Try the following curl command to ensure tor is working properly.
curl --socks5 localhost:9050 --socks5-hostname localhost:9050 -s https://wtfismyip.com/json
Can you try this
package main
import (
"context"
"fmt"
"io/ioutil"
"net"
"net/http"
"golang.org/x/net/proxy"
)
func main() {
proxyUrl := "127.0.0.1:9050"
dialer, err := proxy.SOCKS5("tcp", proxyUrl, nil, proxy.Direct)
dialContext := func(ctx context.Context, network, address string) (net.Conn, error) {
return dialer.Dial(network, address)
}
transport := &http.Transport{DialContext: dialContext,
DisableKeepAlives: true}
cl := &http.Client{Transport: transport}
resp, err := cl.Get("https://wtfismyip.com/json")
if err != nil {
// TODO handle me
panic(err)
}
body, err := ioutil.ReadAll(resp.Body)
// TODO work with the response
if err != nil {
fmt.Println("body read failed")
}
fmt.Println(string(body))
}

As suggested in the answer/comment above, main problem was socks5 connection to dockerized tor container.
Found the solution here, i just had to modify dockerfile like -
FROM alpine:edge
RUN apk update && apk add tor
RUN cp /etc/tor/torrc.sample /etc/tor/torrc && echo "SocksPort 0.0.0.0:9050" > /etc/tor/torrc
EXPOSE 9050
CMD ["/usr/bin/tor"]
Other code pieces are working fine.
