9. Copy imldds.ini to recv.ini and edit recv.ini ReceiverMulticast IF4 Set the IP address to your local SOI server ReceiverIdentity Set Identity for this software (soi-ait, soi-sfc, soi-unsrat…..) TraceServerName Set IP address of the sender(202.249.25.238) LogMode Set log mode to 0 ReceiverHostBasePath Set data storing folder to / Edit mcdd configuration file

10. Preparation of script file. 1. Copy the script to /soi/soi/util/. % mkdir /soi/soi/util/ %cp /mnt/cdrom/customize_lecture.pl /soi/soi/util/ 2. Change file access permissions % chmod 775 /soi/soi/util/customize_lecture.pl

11. Section3. Sending/Receiving files by SAKURAFUBUKI3rd

12. Using web interface Input URL to web browser http://your soi-server ip address:19880/admin
