Re: [SR-Users] Configuring TLS and WSS with Kamailio - sr-users

18 Oct 2014

      Hi
Thanks a lot for your reply. I'll check the cn and let you know. In my configuration I'm listening to tcp port but no tls port? Can that be the reason? Otherthan that if it was rejected because of the certificate shouldn't I get some errors in the log? Every time I'm trying it's getting request timed out.

Hi Ben,
In regards your certificates, please double check the following:
a) CN field:
In your webrtc client check the URL used for wss. and verify it matches the
CN field of the certificate installed in kamailio:
Example:
In my sipml5 client I configured wss://ramenlabs.io:5063 and my certificate
in fact contains in the cn field ramenlabs.io
Subject: OU=Domain Control Validated, OU=PositiveSSL, CN=ramenlabs.io
openssl x509 -in /etc/certs/sip.192.168.146.133/cert.pem -noout -text
b)
I have successfully configured Kamailio 4.1 with TLS and WSS using TLS port
5063
Topology:
1) sipml5 --wss--> ngnix -wss-> kamailio (sip registrar)
2) sipml5 --wss---> kamailio
Relevant configurations:
kamailio.cfg
tls.cfg
certificates
Kamailio:

ok. I have made some changes. rather than getting the TLS configaration
from a file I added this lines:

modparam("tls", "certificate", "/etc/certs/sip.192.168.146.133/cert.pem")
modparam("tls", "ca_list", "/etc/certs/demoCA/cert.pem")
now, Im getting different logs which looks good.  Getting positive results
from openssl test,
openssl s_client -connect 192.168.146.133:5061 -tls1
CONNECTED(00000003)
^C
But when I try to connect using my webRTC client or even from web-browsers
im getting timed out. I think im  close .. please help me fixing this issue.

Out of curiosity, why don't you use the pre-built packaged binaries
instead of building from source?

Hi,
Im trying to connect my WebRTC clietn to kamailio via WSS. I
successfully connected it via WS but having trouble connecting it via WSS.
My first issue is I get error messages while i try to compile TLS
module(console log in the end of the document). But, still it creates
tls.so file. So i copied the tls.so to my kamailio modules directory and
then updated my kamailio configuration as below:
#!define WITH_TLS
.
.
listen=tcp:127.0.0.1:5061
listen=tcp:192.168.146.133:5061
.
.
#!ifdef WITH_TLS
enable_tls=yes
#!endif
.
.
#!ifdef WITH_TLS
# ----- tls params -----
modparam("tls", "config", "/usr/local/kamailio-devel/etc/kamailio/tls.cfg")
#!endif
Now, according to this mailing list,
http://lists.sip-router.org/pipermail/sr-users/2013-March/077182.html : “*when
tls module is installed, a self signed pair of certificate-private key is
generated in /usr/local/etc/kamailio”*
In my case, I dont even have the /usr/local/etc/kamailio directory. So,
I followed
http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates to
create my certificate and key. And updated my tsl.cfg, this is how my
tsl.cfg looks like:
[server:192.168.146.133:5061]
method = TLSv1
verify_certificate = no
require_certificate = no
private_key = /etc/certs/sip.192.168.146.133/key.pem
certificate = /etc/certs/sip.192.168.146.133/cert.pem
ca_list = /etc/certs/demoCA/cert.pem
[client:192.168.146.133:5061]
verify_certificate = yes
require_certificate = yes
Then I restarted my kamailio server. And i get the following errors in
my kamailio log:
Im not sure what wrong im doing. Please help me:
