How to run Yima Client Program

1. turn on the audio volume
2. turn on the projector, which should be turned off after the demo.
   • press operate button on a remote-control
   • if projector blinks a green light, or emits other colors than green, remote-control would not work.
   • if you want to change to a hdtv screen, press computer button on the remote-control until hdtv/1080 message is shown on the projected screen.
3. if you are not sure how to launch server program, go to next step.
   • login to the remote server: ssh -l yima imsc.nge.isi.edu
   • make sure that the kernel network buffer has assigned enough space.
     cd /proc/sys/net/core
     echo 16777216 > rmem_max
     echo 16777216 > wmem_max
     echo 16777216 > rmem_default
     echo 16777216 > wmem_default
     
   • make sure that there's no yima server instances running now
   • make sure that server has enough space to store log infos. sometimes, server will be crashed when there's no space available. the primary reason why it usually lacks in storage space is that log file is growing continuously because it does not erase in time. please erase log file whenever you run the server program.
