Timeout for AFL

[Jln Wntr]

Is it possible to stop AFL-fuzz after a specified amount of time (for example 24 hours) ?

What would be a good practice for "remotely" start and stop AFL-Fuzz from another program?
The fact that AFL uses something like an internal fork-server makes me wonder if it's a good idea to have another C-Program forking AFL.

Hi,

I'd use this one:

Why not just use a Unix shell?

You can use timeout(1) from coreutils to send SIGINT, which should be
equivalent to pressing Ctrl+C:

timeout -s INT 24h afl-fuzz ...
