Sorry for the low level questions but I have two point which I need to better understand: SO : SCIENTIFIC LINUX 5.5 a) yum In /etc/cron yum.cron correspond to the orginal.yum.cron so some autoupdates are enabled in yum.excludes are defined the packages which are not updatet in mine for example thereis kernel* so the kernel should be not updatet
instead an update of the kernel was done! Why? b) installation of sendmail installed latest associated to SL5 turn on the run of the service at boot (level 3 and 5) the sendmail deamon is started the configuration is the standard one try to send an e-mail results dead.letter? Forgot somethings?
