stopping script execution

[martinasv]

Hello guys and gals!

I have a perl script which captures ARP packets on the network.

Right now I'm starting it from command-line and stopping it with Ctrl-C.

But, I'd like to start it and stop it from perl/CGI stript (HTML page, Start and Stop buttons).

I know I could start it using backticks or system(), but how do I stop it?

Hi

Start it in background, write its PID in a file, then kill it using that PID ?

OK, I'll try that.

There has to be a more graceful way?

Pass a capture/nocapture||terminiate signal to the process, rather than kill by PID ($$)

Just a thought

Hi

Of course Paul, I meant so. While the default signal sent by the [tt]kill[/tt] command is SIGTERM ( 15 ), I did not specified it, but of course, sending the SIGKILL ( 9 ) should be the last solution for misbehaving programs.

Yeah, that's a pretty common way to manage services. Check /var/run/*.pid on most *nix systems.
