Hi
This is regarding nc's proxy capability.
I've been facing an issue where as per the man-page of nc it should
work, but effectively didn't.
In my case, I launched the following and was expecting nc is asking for
Proxy password.
Instead the following happened:
$ nc -x192.168.80.80:8080 -Xconnect -Pproxyuser $destination 80
nc: Proxy error: "HTTP/1.1 407 Proxy Authentication Required"
A little research of the source code comparing a traffic catpure
revealed the problem.
Our proxy is responding with the string HTTP/1.1 407 Proxy
Authentication Required\r\n
But asking for password is only approached if the string starts with
HTTP/1.0 407.
This patch addresses the Proxy Password support also for HTTP/1.1 aware
HTTP proxies.
Would be great if this could be merged on upstream.
Thanks
