Hello!

I think you may consider upgrade, we have removed logic to automatically generate packet dumps when they are disabled.

You can upgrade this way:
sudo apt-get update
sudo apt-get install --only-upgrade fastnetmon

Hi Pavel,

Attack dumps and logs seems to be growing fast even though I have them disabled. Do they have a limit and rotate at some point? Am I using the wrong configuration parameters?

Hello!

Can you remove all attack dumps and then wait for some detected attacks?

Maybe they’re just old ones happened before upgrade?

It’s safe to remove all files in attacks_dump folder.

Hi Pavel,

Still getting dumps, but I can have a cron removing old entries anyway. It's nice to have the most recent ones.

show main collect_simple_attack_dumps
disabled

show fastnetmon_version
2.0.217 adb3944c9f10af49ba444e59c240c5172a64e226 

Thank you.
