What signal should i send to process to save and close this tool? SIGINT kills the process without pausing the progress, CTRL_C_EVENT does literally nothing

P.s coding some stuff on python, trying to emulate CTRL+C with os.kill(pid,signal.CTRL_C_EVENT)

I want to get this message:

waiting several seconds to exit...
saving resume file to: paused.conf

I have had trouble with this in the past as well, it'd be great to know if this is possible.

sudo killall masscan or sudo killall -KILL masscan

lynrayy commented 9 months ago

sudo killall masscan or sudo killall -KILL masscan

  1. I'm on windows
  2. I'm using python to stop the process
  3. 'kill' just kill the process instead of save and stop it

Yep exactly the same for me

masscan has a signal handler setup for Ctrl-C (SIGINT). https://github.com/robertdavidgraham/masscan/blob/9065684c52682d3e12a35559ef72cd0f07838bff/src/main.c#L1333

If you have masscan running in the foreground of your terminal just hit Ctrl-C. Or you can send the signal, e.g. kill -s int $(pidof masscan) - you may need sudo if masscan is running as root.

This will cause masscan to wait several seconds and save the paused.conf

waiting several seconds to exit...
saving resume file to: paused.conf

This works for me on Linux.

I haven't tested it on Windows. If you can't get it to work nicely on Windows, you could try using WSL, or Docker.
