Services to Shutdown
- apmd (we don't have a battery backup or a laptop)
- rpcbind
- bluetooth
- isdn (we don't have isdn)
- mdmonitor (unless you are using software raid)

properly, and we don't need it)
- nfs and nfslock (ditto)
- sssd (system security sevices daemon, requires LDAP be configured))
- lvm2-monitor (logical volume manager)
- portmap (many security issues, avoid if you can)
- rpcgssd

Technically, any service that you don't need should be turned off.
Normally the following services are left on as you need them, but all of
them can and have been hacked in the past. Remember to update all services you keep running.
- Edit runlevels (ours is in /etc/rc.d/rc3.d ) using chkconfig --level 3 servicename on/off Or use the GUI tool
- You can turn a sevice on or off using service servicename start|stop||restart|status
- Updates are best at the command line yum update
Services that are optional(not optional for CIS226AL class)
- vsftpd (ftp server)
- httpd (web server)
- ntpd (network time protocol)
- sendmail/postfix (email server)
