Hi Henning,
I've been over that section a number of times, but it is still not clear why Dispatcher would return from ds_select_dst a host that is in IP state. "I" is Inactive.
What does "Probing" mean? Does it imply something besides "we're trying to send OPTIONS packets"?
Regards,
Jawaid

Hello,
not sure what the "auto-probing" mode is, but you can configure the dispatcher OPTIONS ping behaviour with that parameter:

Hi Alex,
I don't see "auto-probing" in the documentation.. here is my dispatcher config that I snatched from somewhere on the Internet.
modparam("dispatcher", "db_url", "mysql://xxxxxxx/kamailio") #Use DBURL variable for database parameters modparam("dispatcher", "flags", 2) # If flag 2 is set, then the failover support is enabled. modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "ds_ping_interval", 5) #How often to ping destinations to check status modparam("dispatcher", "ds_ping_method", "OPTIONS") #Send SIP Options ping modparam("dispatcher", "ds_probing_threshold", 5) #How many failed pings in a row do we need before we consider it down modparam("dispatcher", "ds_inactive_threshold", 10) #How many sucessful pings in a row do we need before considering it up modparam("dispatcher", "ds_ping_latency_stats", 1) #Enables stats on latency modparam("dispatcher", "ds_probing_mode", 1) #Keeps pinging gateways when state is known (to detect change in state)

Unless you have auto-probing enabled, yes.

Hi, is this expected behavior? I have two target hosts in a dispatcher set, 10.20.20.118 (prio 5) and 10.20.20.252 (prio 10). When I have 10.20.20.252 turned off, dispatcher still tries to send packets to that host, even when the status flags are IP. root@vs-rs01:/etc/kamailio# kamcmd dispatcher.list { NRSETS: 1 RECORDS: { SET: { ID: 1 TARGETS: { DEST: { URI: sip:10.20.20.252:5060 FLAGS: IP PRIORITY: 10 LATENCY: { AVG: 0.000000 STD: 0.000000 EST: 0.000000 MAX: 0 TIMEOUT: 62 } } DEST: { URI: sip:10.20.20.118:5060 FLAGS: AP PRIORITY: 5 LATENCY: { AVG: 3.876000 STD: 2.965000 EST: 5.058000 MAX: 14 TIMEOUT: 0 } } } } } } __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions To unsubscribe send an email to sr-users-leave@lists.kamailio.org mailto:sr-users-leave@lists.kamailio.org <mailto:sr-users-leave@lists.kamailio.org mailto:sr-users-leave@lists.kamailio.org> Important: keep the mailing list in the recipients, do not reply only to the sender!
