[OpenSIPS-Users] tls_mgm domain database configuration

[James Nicholls]

Hi all,

I have an existing opensips 3.3.4 setup that uses modparam to set tls_mgm certificates with separate server_domain and client_domain entries. This works fine for registration and calling using TLS but I want to be able to update certificates with tls_reload so I'm trying to move them to the database instead.

The tls_mgm table schema added by opensips-cli has a domain and type column. Does "type" mean client/server or is it something else? I have tried having separate entries for client/server certs, or combining them into one row, but I can't get it to work. Everything seems to result in "no TLS client domain found" as below.

Apr 05 16:02:34 (hostname) /usr/sbin/opensips[22277]: ERROR:proto_tls:proto_tls_conn_init: no TLS client domain found

Example row in the tls_mgm table:

          domain: (SIP branded hostname)
match_ip_address: (opensips IP):4003
match_sip_domain: *
            type: 1
          method: TLSv1_2-
     verify_cert: 0
    require_cert: 0
     certificate: -----BEGIN CERTIFICATE----- [...]
     private_key: -----BEGIN RSA PRIVATE KEY----- [...]
   crl_check_all: 0
         crl_dir: NULL
         ca_list: /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
          ca_dir: NULL
     cipher_list: NULL
       dh_params: NULL
        ec_curve: NULL

Is there any documentation for adding certificates to the tls_mgm table? I haven't found anything in the 3.3.x docs, the only examples use modparam. Hopefully I have got something really obvious wrong.

Kind regards,

James Nicholls
