Connect to server running on the same machine #51

DUOLabs333 commented 2 years ago

I have a Macbook, and I want to run microsocks on it. However, when I added it in Network settings, I can see in the logs that it's connecting, but using curl -x socks5h://localhost:1080 google.com gives me Empty Reply, and Chrome fails to load the page.

rofl0r commented 2 years ago

can you try the latest release ? it may have been broken inadvertently by the last commits. also an strace of the server process would be interesting. (on mac, there's dtruss).

DUOLabs333 commented 2 years ago

Still doesn't work. The trace is from the last release:

<removed useless huge paste>
DUOLabs333 commented 2 years ago

This does happen with SSH and shadowsocks, so it might be a limitation in the SOCKS protocol.

rofl0r commented 2 years ago

the thing you pasted doesnt actually give me a trace. rather, it appears to be the tracing script.

DUOLabs333 commented 2 years ago

Oh, I had to disable SIP first. It doesn't crash though, so how long do I hold the trace?

rofl0r commented 2 years ago

it should be sufficient to have one failed transaction in the trace.

DUOLabs333 commented 2 years ago

Here's a stack with it failing: https://pastebin.com/CR5LtX8Z

rofl0r commented 2 years ago

it takes until about line 1000 to see the first connect(), therefore it appears the previous connections dont even reach line 187. maybe sprinkle a couple debug printfs into that function to see what it does and how far it gets.

DUOLabs333 commented 2 years ago

I do want to say that no connections go through, though.

rofl0r commented 2 years ago

what are you doing, anyway? you mentioned shadowsocks and ssh. please provide more details.

DUOLabs333 commented 2 years ago

I just want to connect to a SOCKS proxy that is running on the same machine. SSH and shadowsocks are two ways to run SOCKS proxy.

DUOLabs333 commented 2 years ago

Interestingly enough, if I run it on another IP address (like the one provided by Wireguard), it now gives "SOCKS_CONNECTION_FAILED".

change line 57 to 128*1024 and recompile

DUOLabs333 commented 2 years ago

Line 57 in which file?

in THE file, sockssrv.c

DUOLabs333 commented 2 years ago

Still says "Connection Closed".

DUOLabs333 commented 2 years ago

I got it to work -- apparently, it is a problem with MacOS's Proxy configuration. Using FoxyProxy solved this problem.
