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?
