fgssfgss / socks_proxy Goto Github PK

So I've mounted the proxy on port 1080,
Great tool by the way, then on requesting Google,

curl --ipv4 --socks5 127.0.0.1:1080 https://www.google.com --verbose

I've got:

*   Trying 127.0.0.1:1080...
* SOCKS5 connect to IPv6 2800:3f0:4005:407::2004:443 (locally resolved)
* Failed to receive SOCKS5 connect request ack.
* Closing connection 0
curl: (97) Failed to receive SOCKS5 connect request ack.

Does anyone have any clue?

Just want to say sank you!

Hello 👋

I run a security community that finds and fixes vulnerabilities in OSS. A researcher (@acquykhud) has found a potential issue, which I would be eager to share with you.

Could you add a SECURITY.md file with an e-mail address for me to send further details to? GitHub recommends a security policy to ensure issues are responsibly disclosed, and it would help direct researchers in the future.

Looking forward to hearing from you 👍
