Wireshark was missing . From: Laurent Schweizer Sent: lundi, 26 août 2019 10:25 To: 'Kamailio (SER) - Users Mailing List' <[email protected]> Subject: Kamailio 5.0.8 | authentification issue only with TCP/TLS
Dear all,
I have a kamailio running in version 5.0.8 and since fee weeks we have an issue
with different users connected in TCP or TLS, sometimes authorization like for
REGISTER are rejected and after a moment (can be few minute or hours) it work
again and of course no change was done in the password ....
We see this issue with different device, snom swyx, ... and on UDP we have no
issue.
I can see that when the Register is rejected it's with the error -2, so wrong
password...
# Authentication route
route[AUTH] {
if (is_method("REGISTER"))
{
# authenticate requests
if (!auth_check("$fd", "subscriber", "1")) {
switch($retcode) {
case -1:
sl_send_reply("503","Service not
available");
exit;
case -2:
xlog("L_WARN", "auth error -2 username
$au - src ip: $si \n");
auth_challenge("$fd", "0");
exit;
I have attached an example of a trace where we can see a first REGISTER
accepted and less than 2 minutes after a new one is rejected. ( in between
they is a REGISTER without any Authorization header)
Any idea ?
BR
Laurent
