Hi people, I am trying to use yum with Fedora Core 1 and I am behind FTP and HTTP proxies and a firewall. I note the final entry in the man page: Proxy configuration If you would like to use a proxy with yum you can simply set a shell environment variable of http_proxy. Set it to the url for your proxy. Ex: "http://your_proxy:port/" This variable has been set by adding a line to .bashrc as follows: export http_proxy=http://[actual http proxy url removed from here]:80 and have confirmed that this variable is set after logging in as root. I have also tried setting this variable to point to the FTP proxy. I am trying to use yum with local (Australian) FTP servers and have confirmed that I have access to these servers. My best guess is that yum is trying to open FTP ports on the HTTP proxy, but I cannot access this device to confirm... Can anyone offer any further assistance?
