I am new working at the present job. All network traffic at this site is controlled by a proxy server. Most people just work with Microsoft systems and probably just browsers as well. I am building a Linux cluster running Fedora 5. I would like to keep things up to date with YUM. I got the browsers working. I can use wget to get files with http_proxy set in my .profile. I couldn't get ftp to work. When I try to run "yum update", I got: Loading "installonlyn" plugin Setting up Update Process Setting up repositories livna [1/7] livna 100% |=========================| 951 B 00:00 flash [2/7] flash 100% |=========================| 951 B 00:00 core [3/7] http://download.fedora.redhat.com/pub/fedora/linux/core/5/x86_64/os/repodata/repomd.xml: [Errno 4] IOError: <urlopen error (-2, 'Name or service not known')> Trying other mirror. Cannot open/read repomd.xml file for repository: core failure: repodata/repomd.xml from core: [Errno 256] No more mirrors to try. Error: failure: repodata/repomd.xml from core: [Errno 256] No more mirrors to try. It looks like I got livna and flash but cannot get anything from fedora.redhat.com. Can anyone knowledgable tell me what I am doing wrong? Lee
