Hi,

    How to run Perl external program in freeradius? especially, first.pl program must be run when client login, second.pl program must be run after client disconnected.   so, how to do it? anyone any idea please?

read the perl module docs and then do the following create 2 perl modules - one called 'perl_login' and one called 'perl_logout'. ensure both of them are enabled...and call the correct program (first.pl and second.pl) in the relevant subroutine (read the example perl code example.pl) now, in the post-auth section, call perl_login and in the accounting section call perl_logout IF the accounting request is a stop. oh, yes, your kit is going to have to do accounting for this to work - as a client doesnt send a logout via RADIUS auth. alan
