Linux daemon introduction
AMD: Automatically install NFS (Network File System) Shou Hou Process APMD: Advanced Power Management ARPWATCH: Record the log and build an Ethernet address and IP address as seen on the LAN interface and IP address AutoFS: Automatic installation management process Automount, related to NFS , Dependent on the NIS BootParamd: Boot Parameter Server, provides the relevant information required for boot to the diskless workstation on the LAN, crred: Linux plan task DHCPD: Start a DHCP (Dynamic IP Address Assignment) server Gated: gateway routing process, Using dynamic OSPF routing protocol httpd: web server inetd: Supporting a variety of network services core waiting program InND: USENET News Server LinuxConf: Allows the use of local web servers as user interfaces to configure machine LPD: print server MARS-NWE: MARS- NWE file and print server MCserve: midnight command file server named: DNS server Netfs: Install NFS, Samba and NetWare Network File System Network: Activate Script Programs Configured Network Interface NFS: Open NFS Service NSCD: NSCD (Name Switch Cache Daemon server, a support service for NIS, high speed cache user password and forms member relationship Portmap: RPC Portmap Manager, similar to inetd, managing RPC-based connection PostgreSQL: A SQL database server ROUTED: Route Swing Process, using dynamic RIP routing protocol RSTATD: A waiter RUSERD: RUSERD: Remote User Location Service for other machines on the LAN: Remote user positioning service, this is an RPC-based service, which provides information about the current record to LAN User information in a machine log Rwalld: Activate the RPC.Rwall service process, which is a RPC-based service that allows users to write messages to each other terminal registered to the LAN machine: Activate the RWHOD service process, which supports LAN RWHO and Ruptime Service Sendmail: Mail Server Sendmail Smb: Samba File Share / Print Service SNMPD: Local Simple Network Management Process Squid: Activate Agent Server Squid Syslog: A script XFS for starting syslog and klogd system logging processes when system boot : X Window Drawing Server, provides a word set for local and remote x servers XNTPD: Network Time Server YPBI ND: For NIS (Network Information System) Client Activation Ypbind Service Process YpSwdd: NIS Password Server Ypserv: NIS Primary Server GPM: The Identd: Auth Service of the Mouse is available in providing user information and Finger similar to Linux system boot service. What is the function? What can be turned off? Linux To launch a lot of system services while starting, providing local and network users with Linux system function interface, direct application and user. However, services that open unnecessary or vulnerabilities will give the operating system security and performance. Below we take the boot service of BluePoint Linux 2.0 as an example, the list describes the functions of the services.
Alsasound ALSA Sound Card Driver Support. The ALSA sound card driver was originally written for a sound card Gravis Ultrasound (GUS), which was clearly excellent, so the author started to write drivers for the general sound card. ALSA and OSS / Free and OSS / Linux are compatible, but have their own interface, even better than OSS. AMD runs the Automount Elf program, which automatically installs some local devices and NFS file systems when necessary. The APMD APMD is used to monitor the system's electricity status and write related information to the log through Syslogd. It can also be used to shut down when the power is insufficient. ARPWATCH This program is mainly used to maintain the correspondence between the Ethernet physical address and the IP address. Atalk AppleTalk wizard. Be careful not to run the program in the background, the data structure of the program must be initialized for a certain period of time before running other processes. ATD runs the task that the user scheduling with the AT command. Batch tasks are also run when the system load is relatively low. Autofs automatically reprints the file system when you need it, and automatically uninstall when you don't need it. Bootparamd This service allows old Sun workstations to start from Linux network, which is rarely used with RARP, basically replaced by bootp and dhcp. Crond cron is a traditional program under UNIX that periodically runs user scheduling tasks. Compared to traditional UNIX versions, the Vixie version adds a few attributes, and is safer and simpler. DHCPD This wizard provides access support for dynamic host control protocols (Dynamic Host Control Protocol). Gated Gated provides network routing function support through a database. It supports various route protocols, including RIP versions 1 and 2, DCN Hello protocol, OSPF version 2, and EGP versions 2 to 4. GPM GPM provides a mouse support for Linux programs for text mode such as MC (Midnight Commander). It also supports copy, paste operation, and pop-up menu under the console. HTTPD HTTP is a famous WWW server that can be used to provide HTML files and CGI dynamic content services. inetd Internet Operating Server. Monitoring the needs of the network to various services of its management, and start the corresponding service programs when necessary. Typically, inetd managed programs include Telnet, FTP, RSH, and Rlogin. Turning off inetd also closes these services managed by it. InND Inn is the most popular user group news server. It allows you to build a local news server. Configure a certain difficulty, you can read the / usr / doc / inn * document first. The keytable functionality is to reprint the keyboard mapping table that you speak in / etc / sysconfig / keyboards, which can be selected by the KbdConfig tool. You should make the program in the active state. LDAP LDAP represents LightWeight Directory Access Protocol, implements industry standards for directory access protocols. LinuxConf LinuxConf is a valid system configuration tool under Linux that allows remote operation. LPD LPD is the system print daemon, which is responsible for submitting LPRs and other programs to the print job. The MCSERV MIDNIGHT COMMANDER service process allows users on the remote machine to operate the native files via the Midnight Commander File Manager. The service process uses a PAM to verify the user, and the "user name / password" needs to be given. MySQL a quick and efficient and reliable light SQL database engine. Named Domain Name Server, resolve the Internet hostname into points of the IP address. Netfs is responsible for loading / unloading NFS, Samba, NCP (NetWare) file systems. Network activation / closes all network interfaces at startup.
