For those who don't know this device, it's common and cheap AP which runs Linux. It seems like i'm runnign in some memory problems. The the device has 16 MB main memory at all. Currently I have roghly 5 MB left. Anyone with an idea how to reduce the memory consumption of snort? This error is what appears on snort startup: Allocating memory for WifistateTable... ERROR: WSTDoTable failed to map requested length into memory: Cannot allocate memory Fatal Error, Quitting.. Thanks for your help! Steffen Pfendtner ------------------------------------------------------------------------ Hi Steffen, Default lenght for wifi_statetable is 218.Which means that if you are using all 3 preprocessors requiring it, you will need
around 10 MB.If you wan't to reduce this, you 'll have first to edit src/wifi_statetable.h file.
Then, replace WST_LENGHT value by 1<<10 instead of 1<<18. Do make clean and compile again. Now wifi _statetable will require 39 KB. By this way you will reduce memory consumption for around 10 MB.
