Re: stop trapd serivce on windows timeout?
Hello Huy, The Win32 snmptrapd calls closesocket() on the UDP socket(s) owned by snmptrapd to make select() stop. While this seems to work with some Windows versions (e.g. Windows XP), this is undocumented Winsock behavior. So whether or not this works may depend on the Windows version. On which Windows version did you observe this behavior ? Bart.

Re: stop trapd serivce on windows timeout?
On windows XP service pack 3 it does not seem to stop in a timely manner. If I put in the call WSACancelBlockingCall() then it break out fine. I will test it on several version of windows and will broadcast what I learn from it. thanks, Huy From: Bart Van Assche To: Snmp Nmcsnmp Cc: net-snmp-users@lists.sourceforge.net Sent: Sat, May 22, 2010 3:44:07 AM Subject: Re: stop trapd serivce on windows timeout?

Re: stop trapd serivce on windows timeout?
Hello Huy, Are you aware that WSACancelBlockingCall() has been removed from Winsock 2, and that Net-SNMP needs Winsock 2 in order to support IPv6 ? See also http://msdn.microsoft.com/en-us/library/ms741547%28VS.85%29.aspx. So two possible solutions are: * Add a Windows-specific alarm to snmptrapd that is triggered e.g. once per second. This will limit the timeout argument of select(). See also the documentation of snmp_alarm_register() on http://www.net-snmp.org/dev/agent/group__snmp__alarm.html. * Or, more elegant, use a socket pair to let select() return when a service stop is requested. A socket pair can be created by calling create_winpipe_transport() (see also snmplib/winpipe.c). The read end of the socket pair can be registered for use in the select() call by calling register_readfd(). Bart.

Hello Huy, Please file a bug report or a patch for this issue such that it doesn't get forgotten. Bart.
