Essential System Administration, 3rd Edition

Managing Network Daemons under AIX

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.
