Mining using a proxy

[almbfsek]

hello guys,

I have an SSH tunnel that I use as a SOCKS proxy for my web browser. I would also like to use it with mining softwares.
is it even possible? I thought since miners use HTTP protocol it should be possible.
if so, which 3rd party application can I use in order to route the miner's connection through the proxy? or may be the miner's code should be modified?

thank you in advance

if your miner uses something like libcurl, it will respect the http_proxy environment variable, look into the underlying software/libs you're using and research their proxy support

You can tunnel your localhost port to any homepage.
e.g. localhost:8332 --> pool.com:8332

You can even change port numbers in the process (if you use several pools)
e.g. localhost:8555 --> otherpool.com:8332

Then you connect your miner to localhost:8332 instead to the pool's address.

for the record my work has a proxy and my miner works fine without having to configure anything extra.

have you actually tried this? I have and depending on how the pool's rpc server is configured, it may not return the data if the request it gets doesn't contain the desired host (e.g. Host: localhost as opposed to actual hostname of the pool server).  Again this depends on the config of the pool but i ran into issues trying to do it this way.

If you really want to scale better, run a proxy service like https://github.com/cdhowie/Bitcoin-mining-proxy (this is what i'm using)

@cynikal: thank you. http_proxy is what I was looking for. I did "export http_proxy=socks5://127.0.0.1:11334" and it doesn't work because according to this(http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTPROXY) my curl version(7.21.3) doesn't support protocol prefix(socks5://) on the URL. so I did some research but I couldn't find how to specify socks5 with env. variables. do you know how?

thank you

thank you

sorry, i use a http proxy myself (i run one on a server remotely and then i ssh tunnel to that proxy directly, rather than use ssh tunnel as a socks proxy).  upgrade your curl version? or staticly compile a local version of newer libcurl and link/include that static lib into your miner ?

[almbfsek]

upgrading the libcurl is the easiest I guess, thanks!

[almbfsek]

well modifying the source was easier afterall

curl_easy_setopt(curl, CURLOPT_PROXY, "socks://127.0.0.1:11334");
curl_easy_setopt(curl, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);

works like a charm...
