Re: [SR-Users] usrloc - ka_mode timeout

Hello,

have you watched for how long it stays in memory? The usrloc keepalive should leverage the same mechanism that was used by the keepalive done by nathelper module, it should not delete the record immediately, but after ka_timeout elapsed from the last received keepalive, then expires is set to current timestamp + 10 seconds, so the next timer cleanup should remove with.

Can you get the kamctl up dump for the phone you tested with? The keepalive related attributes (last keepalive timestamp, last rtt) should be in the json output/

Cheers, Daniel

Hello,

Tried with the latest 5.4 branch, but ka_timeout still not working for me, the record it's still available in ul.dump even if that extension is not replying anymore to the Options sent by the module.

See below used configuration: modparam("usrloc", "nat_bflag", FLB_NATB) modparam("usrloc", "use_domain", FLS_MULTIDOMAIN) modparam("usrloc", "timer_interval", 30) modparam("usrloc", "db_mode", 1) modparam("usrloc", "db_load", 1) modparam("usrloc", "db_insert_update", 1) modparam("usrloc", "matching_mode", 3) modparam("usrloc", "fetch_rows", 4000) modparam("usrloc", "timer_procs", 4) modparam("usrloc", "handle_lost_tcp", 1) modparam("usrloc", "close_expired_tcp", 1) modparam("usrloc", "db_timer_clean", 1) modparam("usrloc", "server_id_filter", 1) modparam("usrloc", "ka_mode", 1) modparam("usrloc", "ka_method", "OPTIONS") modparam("usrloc", "ka_from", "sip:options@devserver.net mailto:sip%3Aoptions@devserver.net") modparam("usrloc", "ka_domain", "devserver.net http://devserver.net") modparam("usrloc", "ka_filter", 0) modparam("usrloc", "ka_timeout", 60) modparam("tm|usrloc", "xavp_contact", "ulattrs")

Thank you Daniel for the latest update, I will try to test the
latest 5.4 branch on the Dev environment and will come back here
for any issues encountered.

    Hello,



    the usrloc keepalive are done on its timer interval:



      -

    https://www.kamailio.org/docs/modules/stable/modules/usrloc.html#usrloc.p.timer_interval
    <https://www.kamailio.org/docs/modules/stable/modules/usrloc.html#usrloc.p.timer_interval>



    For the keepalive timeout I was misled by presence of the global

    variable in the usrloc, but was actually not exported by this

    module. I did it afterwards, just pushed to branch 5.4 as well.



    While is not recommended to run both at the same time, imo

    nothing really bad can happen, you may see more keepalives for

    natted udp contacts (not for tls, tcp, ...).



    As for an unorthodox and untested idea :-) : if you do not want

    to run from latest 5.4 branch yet, you can eventually set

    natping_interval to a very large value, like 20 years in seconds,

    so you are pretty sure you will do an upgrade before nathelper

    timer fires,



    Cheers,


    Daniel

    Hello,







    Is there any way to add those functions from the nathelper

    module to the usrloc module?







    *keepalive_timeout


    natping_interval*







    I'm looking to use ka_mode feature from the usrloc module

    in order to have roundtrip time computed for each extension

    but because those functions are missing in the usrloc module

    and per documentation this functionality conflicts in some way

    with nathelper module it's not recommended to have both

    modules enabled.  Or maybe there is another way to have them

    "interconnected"?









    Thank you.
