My updates are at: http://www.sewak.asr.lan/ftp/pub/yum-repository/redhat/updates/9/x86/ My Yum.conf: [main] cachedir=/var/cache/yum debuglevel=10 errorlevel=2 logfile=/var/log/yum.log pkgpolicy=newest distroverpkg=redhat-release tolerant=1 exactarch=1 #[base] #name=Red Hat Linux $releasever - $basearch - Base #baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/$releasever/$basearch/ [updates] name=Red Hat Linux $releasever - Updates #baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/updates/$releasever/ baseurl=http://www.sewak.asr.lan/ftp/pub/yum-repository/redhat/updates/$releasever/ I don't have a [base] mirror therefore I have commented it. Also, am able to see the following directory listing at http://www.sewak.asr.lan/ftp/pub/yum-repository/redhat/updates/9/ headers/ [directory] x86/ [directory] AND the following directory listing at http://www.sewak.asr.lan/ftp/pub/yum-repository/redhat/updates/9/x86/ athlon [directory] i386 [directory] i586 [directory] i686 [directory] noarch [directory] What I want: - Kernal to be upgraded but earlier kernal not to be removed...multibooting into earlier kernel, if something happens. - I have a PIII-550 Mhz, 512 MB RAM, Single Processor. I hope yum is intelligent enough not to install the Athlon or SMP kernels. Please reassure.;-)) I'm shaking!! Commands that I intend to give: yum -t check-update and if no major probs yum -t update Is this correct? Do I need to do anything else? Please guide. With best regards. Sanjay. PS: Just help me push the button!!
