Description Andreas M. Kirchwitz 2013-08-24 22:15:23 EDT
Description of problem:
When using ncat to connect through a HTTP proxy a debug message is displayed on screen. This breaks automated use of ncat.

$ /usr/bin/ncat --proxy-type http --proxy proxy.example.com:3128 www.example.com 443
NCAT DEBUG: Proxy returned status code 200.

Version-Release number of selected component (if applicable):

How reproducible:
Use ncat to connect through a HTTP proxy.

Steps to Reproduce:
1. see above

Actual results:
Debug message displayed.

Expected results:
No message displayed unless verbose output has been requested.

Additional info:
Fedora 19 had same bug (ticket 994376). If you ask why I'm using "ncat" instead of "nc", that's because "nc" is even more broken for use of HTTP proxy:

$ nc -X connect -x www.example.com:3128 www.example.com 443
nc: Proxy error: "HTTP/1.1 200 Connection established"

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.

request at this time.

Red Hat invites you to ask your support representative to
