Section2.Installation of SAKURAFUBUKI 3rd
1. Installation of SAKURAFUBUKI 3rd
2. Edit mcdd configuration file
3. Start your mcdd program （ verify program process)
4. Preparation of script file.
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
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
