Chapter 6 HPSS Configuration350 September 2002 HPSS Installation GuideRelease 4.5, Revision 26.8.8.2.2 /etc/services, /etc/inetd.conf, and /etc/xinetd.dTo invoke the non-DCE/Encina part of the mover, the remote nodes’ inetd is utilized to start theparent process when a connection is made to a port based on the Mover’s type specificconfiguration (see section 6.8.8).An entry must be added to the /etc/services file so that the inetd will be listening on the port towhich the Mover parent process (running on a DCE/Encina node) will connect. The port numberis one greater than that configured for the “TCP Listen Port” in the Mover’s type specificconfiguration. For example, if the configure listen port is 5001, the following line must be added to/etc/services:hpss_mvr1 5002/tcpFor non-Linux systemsA corresponding entry must be added to the /etc/inetd.conf file, which will define whichexecutable to run and the arguments to use when a connection is detected. The sole argument(other than the program name) is the pathname to a file that will contain an ASCII representationof the configured encryption key for the Mover (see the next section for further details). Forexample:hpss_mvr1 stream tcp nowait root /opt/hpss/bin/hpss_mvr_tcphpss_mvr_tcp /var/hpss/etc/mvr_ekWhich will cause the executable /opt/hpss/bin/hpss_mvr_tcp to be run under the root user IDwhen a connection is detected on port 5002. The Mover process will use the /var/hpss/etc/mvr_ekfile to read the encryption key that will be used to authenticate all connections made to this Mover.After modifying the /etc/inetd.conf file, be sure to refresh the inetd daemon using the followingcommands:% ps -ef | grep inetdroot 6450 3154 0 Apr 29 - 0:02 /usr/sbin/inetdhpss 17852 59370 2 16:50:25 pts/18 0:00 grep inetd% kill -s USR2 6450For Linux systemsA corresponding file must be added to the /etc/xinetd.d directory, which will define whichexecutable to run and the arguments to use when a connection is detected. The file will be given thesame name as the entry in /etc/services. Continuing the above example, a file called /etc/xinetd.d/hpss_mvr1 would be created with the following contents:service hpss_mvr1{disable = nosocket_type = streamprotocol = tcpwait = yes
