I am having problems getting yum and wget to work properly. I get the following error with either one. Connecting to download.fedora.redhat.com|66.187.224.20|:80... connected. HTTP request sent, awaiting response... 400 Bad Request 08:23:01 ERROR 400: Bad Request. We are using squid with authentication on an IPCop box. which is most likely causing the problem, but I am not sure what to put in the config to fix it. I have added the following to yum.conf, but that has not helped. http_proxy=http://user:pass@10.100.100.130:8080
