Hi Guys I have a program called radsqlkill.pl which I am calling from exec like the following: exec radsqlkill { wait = no program = "radsqlkill.pl %{Calling-Station-Id}" input_pairs = request shell_escape = yes output = none } I have it defined in "instantiate" and "authorize" The idea being that it searches for active sessions in the radacct table and kills them using a Disconnect-Request if the same user trys a new connection. This is different to similtaneous use as due to my network setup it is not possible for the same Calling-Station-Id to actually connect twice, which means that they have been disconnected without the NAS noticing if there is a new Auth request from the same Calling-Station-Id. When run from the command line everything works great, however when run from exec I get the following segfault in syslog: Sep 18 17:00:05 server radsqlkill.pl[12254]: Sending Disconnect-Request for 021211111111 to 1.1.1.1 Sep 18 17:00:05 server kernel: radclient[12255]: segfault at 0000000000000058 rip 00002aaaaaf0d869 rsp 00007fffffccbf90 error 4 Does anyone know why this would be a problem? -- Peter Nixon http://www.peternixon.net/ PGP Key: http://www.peternixon.net/public.asc
