Hi Johan,
The issue is probably caused by the fact that OpenSIPS tries to
initialize a 'default' client and server domain and the certificate file
is inexistent at the default path
('/usr/local/opensips//etc/opensips/tls/cert.pem'). So even if you
define your "sv_dom" custom server domain, OpenSIPS still tries to
create default domains for fallback purposes. When you omit the
'[sv_dom]' prefix for the domain settings in your second test, you
overwrite the default ones (with a valid path for the certificate this
time).
In conclusion, either specify your custom domain _and_ default domains
separately (set the modparams multiple times) or make sure the
certificate is found at the default path. Also, note that it's not
necessary to define a custom server domain if you only intend to use a
single one, as the default will match any socket.

Hi,
I believe that I have found a bug in tls_mgm:
Using opensips default certificates:

modparam("tls_mgm", "ca_list",

#### PROTO_TLS module
loadmodule "proto_tls.so"
modparam("proto_tls", "trace_destination", "hep_dest")
modparam("proto_tls", "trace_on", 1)
I removed the passphrase:
mv etc/tls/rootCA/private/cakey.pem
etc/tls/rootCA/private/cakey.pem.protected
openssl rsa -in etc/tls/rootCA/private/cakey.pem.protected -out
etc/tls/rootCA/private/cakey.pem
and then tried to run opensips from cmdline : ./opensips -f
/usr/local/opensips/etc/opensips/opensips.cfg
syslog output:
Feb 17 12:22:01 ns3012072 ./opensips[28673]:

Next I tried with:
loadmodule "tls_mgm.so"
#modparam("tls_mgm", "server_domain", "sv_dom=5.135.140.139:5061")
modparam("tls_mgm", "require_cert", "0")
modparam("tls_mgm", "verify_cert", "0")
modparam("tls_mgm", "tls_method", "SSLv23")
modparam("tls_mgm", "certificate",
"/usr/local/opensips/etc/opensips/tls/rootCA/cacert.pem")
modparam("tls_mgm", "private_key",
"/usr/local/opensips/etc/opensips/tls/rootCA/private/cakey.pem")
modparam("tls_mgm", "ca_list",
"/usr/local/opensips/etc/opensips/tls/rootCA/cacert.pem")
#### PROTO_TLS module
loadmodule "proto_tls.so"
modparam("proto_tls", "trace_destination", "hep_dest")
modparam("proto_tls", "trace_on", 1)
and then opensips starts…
Can you please explain what I am doing wrong ?
