I have been fighting prob where our IT people closed up our router access and forced http through Webmarshal proxy which chains to SquidNT. Being a lone Linux workstation in a W2003 (apart from the FTP server running FC4 ;) I needed to sort myself. Yum HTTP 407 errors means proxy authentication not working. Yum authentication to proxy works using #export http_proxy=http://domain\\user:password@server:8080/ Yum borks on HTTP 400 errors which I found could be resolved by adding keepalive=0 to /etc/yum.conf Yum comes up with [ERROR -1] header length incorrect (or similar) This seems to be related to a malfunctioning proxy that cant handle byte-ranged requests. I found that if I sneaked into SquidNT and added myself to the acl accept list (bypassing Webmarshal) all systems go! and Yum is happy again. So now the question... I have convinced IT to let the FC4 FTP server have direct access to Squid (3128). The FTP server is on 10.0.0.50. How do I forward port 80 from my workstation (10.0.0.99) to the FTP server to then forward through the squid proxy when I run Yum?
