added camera to zm but no picture

[jonnexen]

Hi guys,

I think I installed ZM like described in the documentation.. After that I've added some camera to the ZM interface. My problem now is that I can't see any picture when I click on the name of the cam. Also the events can't be shown in the browser...

What information do you need to help me?

Thanks!

Shared memory?

shmmax_mb=$(expr $shmmax / $mb)

shmmax_cur_mb=$(expr $shmmax_cur / $mb)
shmall_cur=$(sysctl -n kernel.shmall)
echo "-- Total memory = $mem_bytes B = $mem_bytes_mb MB"
echo "-- Page size = $page_size B"
echo "-- Current kernel.shmmax = $shmmax_cur B = $shmmax_cur_mb MB"
echo "-- Current kernel.shmall = $shmall_cur pages"
if [ "$shmmax" -eq "$shmmax_cur" ] && [ "$shmall" -eq "$shmall_cur" ]; then
   echo "-- Recommended shm values already set"
else
   echo "-- Recommended: kernel.shmmax = $shmmax B = $shmmax_mb MB"
   echo "-- Recommended: kernel.shmall = $shmall pages"
fi
# Done
echo "--- Done."

You may have to edit your /etc/sysctl.conf and add the lines with the recommended values and then restart the computer or run sysctl -p.

Hope it helps, credits goes to the author of the script "Pada",

There is a typo in the script "kernel.shmmall" is misspelled.

Or compile with mmap shared memory. this requires zero configuration and is the default option since 1.24.3.

Yes, you're right, but the typo is in the echo command, so is not really important indeed.....Corrected anyway!
