Hello Monks,

I have a perl Expect script that spawns a shell with "sudo su" and then runs an openvpn client on that shell. However, I am having problems terminating the openvpn client (followed by the expect spawned object). The relevant code I am using:

$cmd = "kill -INT $vpnpid";
    KILLVPN:
    print "Sending kill commands to child processes:\n$cmd\n";
    $exp1->send_slow("$cmd\n");
    sleep 3;
    my $ps = `ps -p $vpnpid | grep -v grep | grep -v TTY`;
    if ($ps =~ /\w+/) {
        print "VPN process $vpnpid not dead yet\n $ps \nSending kill -
+TERM\n";
        $cmd = "kill -TERM $vpnpid";
        goto KILLVPN;
    }
    $exp1->hard_close();

On the output I see: 

Got command prompt: [root@fc10-test perl]# Sending kill commands to ch
+ild processes:
kill -INT 3006
VPN process 3006 not dead yet
  3006 pts/4    00:00:00 openvpn

Sending kill -TERM
Sending kill commands to child processes:
kill -TERM 3006
VPN process 3006 not dead yet
  3006 pts/4    00:00:00 openvpn
...

Now if I issue the "kill -TERM 3006" from a shell, it kills the process and my script ends gracefully, but somehow it is not working within the expect shell. Please note that the expect shell is running as root (just as I am when execting the command from another shell).

TIA
