[Yum] [Errno -1] Header is not complete.

Thu Jul 7 13:50:48 UTC 2005

Welcome to yum on a big bad network.  Both the emails you site are 
mine.  Looks like you are behind transparent and silently broken 
proxies.  One way I've found that usually works to detect a transparent 
proxy is this:

echo -e "TRACE / HTTP/1.1\nHost:  yum-server.example.com\n\n"  | nc yum-server.example.com 80

This sends a TRACE (as opposed to a GET or HEAD or POST) http
request, for which proxies are *supposed* to tack on an extra "Via:"
line to identify themselves.  They don't have to, but most of the ones
I've encountered do.

Yum isn't doing anything wrong here.  The answer in the case of "Header
is not complete" is "fix your network".  Your proxies just don't perform
http byte-ranged requests.... usually a simple upgrade of it's OS or
firmware will do the trick. Can you convince your network guys to do
this for you?
