[OpenSIPS-Users] Unable to load my private key file (TLS) in OpenSIPS 2.2. What should I check? Default example worked.

[Rodrigo Pimenta Carvalho]

Hi.


1 - I have read and followed all the instructions on page http://www.opensips.org/Documentation/Tutorials-TLS-2-1 . It is about how to set up TLS in OpenSIPS 2.1. Good tutorial for beginners. But, there is no tutorial for it in version 2.2

2 - I have read all the instructions from page http://www.opensips.org/html/docs/modules/2.2.x/proto_tls.html . This is the OpenSIPS TLS Module Guide.


3 - Considering all instructions I have learnt today, I wrote the following configuration:


----------------------------------------------------------------------------------------------------------------------------------------------------------------


loadmodule "proto_tls.so"

modparam("proto_tls","verify_cert", "1")
modparam("proto_tls","require_cert", "0")
modparam("proto_tls","tls_method", "tlsv1")

#modparam("proto_tls","certificate", "/usr/local/opensips_proxy/etc/opensips/tls/user/user-cert.pem")                # This line was generated automatically, after using the make menuconfig. It works very well.
#modparam("proto_tls","private_key", "/usr/local/opensips_proxy/etc/opensips/tls/user/user-privkey.pem")       # This line was generated automatically, after using the make menuconfig. It works very well.
#modparam("proto_tls","ca_list", "/usr/local/opensips_proxy/etc/opensips/tls/user/user-calist.pem")                   # This line was generated automatically, after using the make menuconfig. It works very well.


 modparam("proto_tls", "certificate", "/home/pimenta/SISC/TLS/tls_cnf/tls/rootCA/cacert.pem")                            # I want to use the files generated by me, following the tutorial on how to set up TLS. No problem here.
 modparam("proto_tls", "private_key", "/home/pimenta/SISC/TLS/tls_cnf/tls/rootCA/private/cakey.pem")            # File also generated by me, following the tutorial. ERROR here.  What is the problem??
 modparam("proto_tls", "ca_list", "/home/pimenta/SISC/TLS/tls_cnf/tls/rootCA/cacert.pem")                                  # I want to use the files generated by me, following the tutorial on how to set up TLS. No problem here.
 modparam("proto_tls", "ca_dir", "/home/pimenta/SISC/TLS/tls_cnf/tls/rootCA/")                                                      # I want to use the files generated by me, following the tutorial on how to set up TLS. No problem here.

4. All paths I'm using in such configuration are real and correct.


5. When I try to run the OpenSIPS, I always got the erro:


Jul 27 18:02:02 [13783] WARNING:proto_tls:mod_init: disabling compression due ZLIB problems

...

...

Enter passphrase for /home/pimenta/SISC/TLS/tls_cnf/tls/rootCA/private/cakey.pem:
Jul 27 18:02:02 [13783] ERROR:proto_tls:load_private_key: unable to load private key file '/home/pimenta/SISC/TLS/tls_cnf/tls/rootCA/private/cakey.pem'.


So, the file cakey.pem cann't be loaded. But, I'm running the OpenSIPS as a superuser.



What should I check in my files to verify whether  I have made some mistake?

To follow the tutorial for version 2.1 and to use the version 2.2 can cause troubles? I tutorial I see "TLSv1" and in the module guide I see "tlsv1". Is the script case sensitive?


The issued file is: -rw------- 1 root root 1834 Jul 24 14:54 /home/pimenta/SISC/TLS/tls_cnf/tls/rootCA/private/cakey.pem. Can it be owned by root user, or must be another one?


I have just googled this case and I found same problem for people who was using wrong key file, which I think is not my case.


Any hint will be very helpful!


Thanks a lot!
