Some services that can be disabled under Linux

Multi-software/multi-script collaboration between Linux:

Includes two things to do with "physical" and "configuration"

"Entity" means a real script file, a service script;

"Configuration" refers to other interaction with the software, script, to be properly configured to tell the "entity" where the existence of information, to work properly

Apmd,acpid power Management and configuration services, only laptops/servers with UPS and batteries configured to open this service

BLUETOOTH,HIDD,PCSCD, Pcmcid:humanization interface device, humanized interface devices, PC memory Card International alliance, belong to the Bluetooth service, you can disable

Dund:dun-daemon, bluetooth Dayton Daemon, mobile phone via Bluetooth and laptop Bluetooth access Internet service

Pand:pan-daemon, pan: Personal LAN, establishing a Bluetooth-based network connection

PCSCD, SD card on PCMCIA:PC machine, memory card Alliance

Haldaemon=hald:hal:hardware abstract layer, hardware abstraction level daemon service:

The USB mouse keyboard is not available. The final investigation found that the Haldaemon service was turned off. Implement automatic mounting of the U-disk involves services:

The biggest feature of Fedra core is the ability to automatically mount storage devices such as a USB stick or a removable hard drive. The HotPlug, Udev, Messagebus, Haldaemon, GAIMN services are essential for the automatic mounting of the function.
Step1, HotPlug is the core, when the hardware Device access system, first detected by the HotPlug service and automatically configure the kernel state, call to add the relevant kernel module.
Step2, Udev is responsible for dynamically maintaining the/dev directory, keeping the/dev directory consistent with the current system state, creating/DEV/SDAX and other device documentation.
Step3, the Messagebus service is responsible for passing messages between the various system processes.
STEP4, Haldaemon accepts the message D-bus passed by Udev Fstab-sync modifies the Fstab document and dynamically creates a subdirectory under the/media directory as the mount point.
STEP5, gamin (fam:file alteration monitoring) "Homeless, GA ' Mine women homeless" is responsible for notifying the desktop system after a change in fstab has been detected. The desktop system creates a drive icon in the computer project.
As a result, it is important to ensure that several of these services start properly when you implement automatic loading of removable storage devices. Typically, the Haldaemon service may be inadvertently shut down during system optimization,

This results in the inability to dynamically change the/etc/fstab document, which prevents the mobile device from automatically being recognized when it is connected to the system. It is now possible to mount manually via the Mount command.
In addition, if the HAL service startup appears to fail when the system starts, it is likely that the Messagebus service is not started. Reboot the Messagebus service and then restart Haldaemon

--------------------------

Mainly through: PS, netstat, chkconfig several commands together to check which background processes and services started, and then targeted processing
