Hi, I am having a bit of problem with making yum work. I am behind a proxy server which requires authentication. After reading some posts and man yum.conf, my yum.cnf looks like (Note: password has been changed) yum.conf [main] cachedir=/var/cache/yum debuglevel=2 logfile=/var/log/yum.log pkgpolicy=newest distroverpkg=redhat-release tolerant=1 exactarch=1 retries=20 obsoletes=1 gpgcheck=0 # The proxy server - proxy server:port number proxy=<a href="http://vsnlproxy.iitk.ac.in:3128/">http://vsnlproxy.iitk.ac.in:3128/</a> # The account details for yum connections proxy_username=spsingh proxy_password=my_passwd and /etc/wgetrc # You can set the default proxies for Wget to use for http and ftp. # They will override the value in the environment. http_proxy = <a href="http://vsnlproxy.iitk.ac.in:3128">http://vsnlproxy.iitk.ac.in:3128</a> #ftp_proxy = "<a href="http://vsnlproxy.iitk.ac.in:3128">http://vsnlproxy.iitk.ac.in:3128</a>" proxy-user=spsingh proxy-passwd=my_passwd # If you do not want to use proxy at all, set this to off. use_proxy = on now yum update gives [root@spsingh sumeet]# yum update Setting up Update Process Setting up repositories <a href="http://rpm.livna.org/fedora/4/i386/RPMS.extras/repodata/repomd.xml">http://rpm.livna.org/fedora/4/i386/RPMS.extras/repodata/repomd.xml</a>: [Errno 4] IOError: HTTP Error 407: Server: squid/2.5.STABLE9-20050429 Mime-Version: 1.0 Date: Sat, 10 Sep 2005 05:58:55 GMT Content-Type: text/html Content-Length: 1445 Expires: Sat, 10 Sep 2005 05:58:55 GMT X-Squid-Error: ERR_CACHE_ACCESS_DENIED 0 Proxy-Authenticate: Basic realm="Squid proxy-caching web server" X-Cache: MISS from vsnlproxy Proxy-Connection: close Trying other mirror.
