Essential System Administration, Third Edition

In general, AIX uses the System Resource Controller to manage daemons, and the ones related to networking are no exception. The startsrc and stopsrc commands are used to manually start and stop server processes within the SRC. The following commands illustrate the facility's use with several common TCP/IP daemons:

# stopsrc -g tcpip Stop all TCP/IP-related daemons. # stopsrc -s named Stop the DNS name server. # startsrc -s inetd Start the master networking server. # startsrc -g nfs Start all NFS-related daemons.

As these commands illustrate, the -s and -g options are used to specify the individual server or server group (respectively) to which the command applies. As usual, the lssrc command may be used to display the status of daemons controlled by the SRC, as in this command, which lists the servers within the nfs group:

# lssrc -g nfs Subsystem Group PID Status biod nfs 344156 active rpc.statd nfs 376926 active rpc.lockd nfs 385120 active nfsd nfs inoperative rpc.mountd nfs inoperative

On this system, the daemons related to accessing remote filesystems are running, while those related to providing remote access to local filesystems are not.
