  • Check a socks5 proxy with netcat.

    From hongyi.zhao@gmail.com@21:1/5 to All on Sat Mar 4 05:29:38 2023
    Based on the comments here [1-2], I tried to test the availability of my socks5 proxy, but failed to get the information I needed:

    werner@X10DAi:~$ echo 050100 | xxd -p -r | netcat 127.0.0.1 18888
    ^C
    werner@X10DAi:~$ printf "\x05\x01\x00\r\n" | nc 127.0.0.1 18888 | hd
    ^C

    But curl will return useful information as follows:

    werner@X10DAi:~$ curl -Ivx socks5h://127.0.0.1:18888 www.baidu.com
    * Trying 127.0.0.1:18888...
    * SOCKS5 connect to www.baidu.com:80 (remotely resolved)
    * SOCKS5 request granted.

    Really, they should be posted to alt.dev.null (if that exists).

    Most of this guy's ("hongy") postings are of the form:

    Hey! I just noticed that the sun is shining. How does that work?
    Isn't that amazing?

    Yes, you're right. Thanks for the heads up.
    I'll be more selective in my replies.
