 Ok, I'm sorry!

I performed the following (if it is not correct, please advise how to make a test):

I took my file 'my_app.rel',  commented out external applications  and created a boot script:

[ test ]$ erl
Erlang R16B01 (erts-5.10.2) [source] [64-bit] [smp:4:4] [async threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.2 (abort with ^G)
1> systools:make_script("my_app", []).

Then I ran two erlang nodes with my certificate:

erl -boot my_app -proto_dist inet_tls -ssl_dist_opt server_certfile "path_to_pem" -ssl_dist_opt client_certfile " path_to_pem " -ssl_dist_opt server_secure_renegotiate true client_secure_renegotiate true -name my_app1 -setcookie 123

erl -boot my_app -proto_dist inet_tls -ssl_dist_opt server_certfile " path_to_pem " -ssl_dist_opt client_certfile " path_to_pem " -ssl_dist_opt server_secure_renegotiate true client_secure_renegotiate true -name my_app2 -setcookie 123


()1> net_adm:ping('').

=PROGRESS REPORT==== 10-Dec-2013::17:28:25 ===
supervisor: {local,inet_gethost_native_sup}
started: [{pid,<0.93.0>},{mfa,{inet_gethost_native,init,[[]]}}]

=PROGRESS REPORT==== 10-Dec-2013::17:28:25 ===
supervisor: {local,kernel_safe_sup}
started: [{pid,<0.92.0>},

So, i can make a conclusion, that the certificate is correct

With best regards,
