Hello Daniel,
Thanks for your quick answer!
I indeed need to identify the group ID too.
Here’s how I handle it (inspired
from https://kamailio.org/docs/modules/5.5.x/modules/permissions.html#permission…):
‘''
$var(group) = allow_source_address_group();
if ($var(group) != -1) {
xlog("L_INFO", "$si : $sp is allowed through group:
$var(group)\n");
[...]
} else {
xlog("L_INFO", "$si : $sp is not allowed - allow_source_address_group
returned -1\n");
xlog("L_INFO", "Rejecting $ci with 403 'Forbidden'\n");
sl_send_reply("403", "Forbidden");
exit;
}
‘''

Hello all,
I am having some trouble with Permissions module of Kamailio,
regarding the allow_source_address_group() function. In 99.9% of the
cases the IP of our partner is allowed as expected, but randomly it
can fail (returning -1 for the same IP address that was allowed for
many other calls in the meantime).
I can’t understand why it fails and why only « sometimes » - I confirm
this append on the same Kamailio box, with same IP and Port of the
partner.
In my custom logs:
« X.X.X.X:YYYY is allowed through group Z » —> as expected
and sometimes (like 1% of the cases): « X.X.X.X:YYYY is not allowed
- allow_source_address_group returned -1»
It is maybe to note that in the address table, this range is defined
as /24 and not /32. Until now it never happened on /32 defined address
but I don’t know if it can be correlated.
Would someone have a clue on this?
Versions:
- kamailio 5.5.0 (x86_64/linux) d4c1a1
- debian 9 stretch
- postgresql 11.7
how do you test the return code of the function? Paste here the snippet
of the config where the function is used.
Then, do you really need the goup id of the address or just to match the
address?
Cheers,
Daniel
