Hi Daniel,

yes, we see this message.

Nov 13 11:44:42 lasola /usr/sbin/kamailio[16113]: DEBUG: <core> [sr_module.c:959]: init_mod(): tls
Nov 13 11:44:42 lasola /usr/sbin/kamailio[16113]: WARNING: tls [tls_mod.c:287]: mod_init(): tls support is disabled (set enable_tls=1 in the config to enable it)
Nov 13 11:44:42 lasola /usr/sbin/kamailio[16113]: DEBUG: <core> [main.c:2520]: main(): Expect (at least) 30 kamailio processes in your process list

Okay, then the message right at the beginning probably just irritated us. But as you can see, we have set enable_tls=1 (previously and in the documentation it was set to 'yes'), but it still doesn't get enabled.

Any more ideas?

Best Regards,

Sebastian

Hello,

if you start with debug=3, do you see the message:

Hello,

we just updated one kamailio server from 4.1.5 to 4.3.3, and although the config file is correct and kamailio starts up, it doesn't initialize TLS and says " tls support enabled, but no tls engine available (forgot to load the tls module?)"

In the log I see:

Nov 13 11:44:42 lasola /usr/sbin/kamailio[16113]: DEBUG: <core> [sr_module.c:959]: init_mod(): sl

In our config file we have the following lines for TLS (pretty late, after all other module loading and after most parameters):

#!ifdef ENABLETLS
loadmodule "tls.so"

modparam("tls", "private_key", "/etc/ssl/private/my.kamailio-key.pem")
modparam("tls", "certificate", "/etc/ssl/certs/my.kamailio.crt")
#!ifdef TLS_CA_CHAIN
# Maybe we want to use a chain to the CA
modparam("tls", "ca_list", "/etc/ssl/certs/my.ca-bundle.crt")
#!endif
enable_tls=1
listen=tls:1.2.3.4:5061
#!endif

After starting up, kamailio listens on port 5060, but not on port 5061. In version 4.1.1, this config worked without a problem.

Has anybody seen this before? the tls module is there and available, it doesn't say anything about "cannot load module", and it is only a warning message. I'm also wondering, why this message is the first after starting the server. From config I would expect that sl, tm and all the other modules should be initialized before tls.

Best Regards,

Sebastian
