Services Manager, seen in Figure 7.4a, is an easy-to-use GUI tool for managing some KDE and FreeBSD services. It allows services to be enabled/disabled at system startup or to change their current status to stopped/running. To access this utility, go to Application Launcher -> System Settings -> Services Manager. You will be prompted to input the administrative password.
Figure 7.4a: Managing Services Using Services Manager
The following services can be managed with this GUI:
- ACPI -
- Avahi -
- cpufreq - a background process (daemon) to adjust CPU speed and voltage on the fly. This can save battery power because the lower the clock speed, the less power the CPU consumes. It is especially recommended for laptop users.
- CUPS - required for printing.
- Denyhosts - a script that analyses log messages to determine what hosts are attempting unauthorised access to your system. It also determines what user accounts are being targeted and keeps track of the frequency of hacking attempts.
- NFS -
- PF - the default firewall for filtering TCP/IP network traffic and doing Network Address Translation (NAT). It's recommended to keep the PF firewall turned on, unless you have installed another firewall or are using a router with a built-in firewall.
- SSH - a network protocol that allows data to be exchanged over a secure channel between two computers by using data encryption. SFTP and (SCP) capabilities are also handled through the SSH protocol.
- swap monitor -
