Hi sccientificlinux community. I am using SL5.5 x86_64 as a desktop that is connected to the web via external ADSL Modem aand I have a question about services running. Assuming that I have only a HP f4480 connected, LCD Mnitor Phillips and DVD/CDROM drive: Did I need all services running? I disable bluethooth.What other services can I disable and maintain performance/security? I have the following services running: acpi anacron atd auditd autofs avahi-daemon cpuspeed crond cups firdtboot gpm haldaemon hplip libasm ip6tables iptables irqbalance isdn jexec kudzu lm_sensors lvm2-monitor mctrans mdmonitor messagebus micrrocode_ctl netfs nfslock pcsd portmap rawdevices readahead_early readahead_later restorecond rpcgssd rpcidmap sendmail smartd sshd syslog yum yum-updatesd Thanks Arturo
