- As far as I know /etc/inetd.conf is the only way to control TCP/IP on
- AIX 3.2.
-
- # /etc/inetd.conf
- #
- # Internet server configuration database
- #
- # Services can be added and deleted by deleting or inserting a
- # comment character (ie. #) at the beginning of a line If inetd
- # is running under SRC control then the "inetimp" command must
- # be executed to import the information from this file to the
- # InetServ ODM object class, then the "refresh -s inetd" command
- # needs to be executed for inetd to re-read the InetServ database.
- #
- # NOTE: The TCP/IP servers do not require SRC and may be started
- # by invoking the service directly (i.e. /etc/inetd). If inetd
- # has been invoked directly, after modifying this file, send a
- # hangup signal, SIGHUP to inetd (ie. kill -1 "pid_of_inetd").
- #
- # service socket protocol wait/ user server server program
- # name type nowait program arguments
- #
- uucp stream tcp nowait root /etc/uucpd uucpd
- ftp stream tcp nowait root /etc/ftpd ftpd
