[Radiusplugin-users] vsascript.pl produce same action result, both of client connect and client disconnect.

[chowalit.lab Chowalit Lab Linux]

Dear all,
      I modify vsascript.pl to keep "print" result to file. Sample of
modified vsascript.pl was here.
...
open(FIFO, "< $pipe") || print "fifo: $!\n";
open (WFILEHANDLE, ">>/tmp/vsa.log") or die ("Cannot open vsa.log .\n");
# keep log into /tmp/vsa.log
my $l;
...
read (FIFO,$l,4);
$action=unpack('N1',$l);
# Keep every print function into /tmp/vsa.log
print WFILEHANDLE "VSAScript: Action: $action\n";

read (FIFO,$l,4);
$reykeying=unpack('N1',$l);
# Keep every print function into /tmp/vsa.log
print WFILEHANDLE "VSAScript: Rekeying: $action\n";
....



   In /etc/openvpn/server.cnf was contain.

...
plugin  /usr/share/openvpn/plugin/lib/radiusplugin.so
/etc/openvpn/radiusplugin.cnf
....


    In /etc/openvpn/radiusplugin.cnf was contain.

...
# Path to a script for vendor specific attributes.
# Leave it out if you don't use an own script.
vsascript=/etc/openvpn/vsascript.pl

# Path to the pipe for communication with the vsascript.
# Leave it out if you don't use an own script.
vsanamedpipe=/tmp/vsapipe
....

             After I restart openvpn service and test openvpn
connection from client. This is vsa.log detail.

    Both of result show the same result. As I found the problem is
vsascript return same action. It show only Client Connect action.

The same result:
VSAScript: Action: 1
Action: Client connect


    I want to use vsascript.pl to run after client-connect and
client-disconnect action. Am I miss something in coding. Please help
me.


Thanks
