I first tried the external configuration file and indeed i had problems. I afterwards used the modparam operation and tried to set different keys and certs created in different ways (openser script, openssl 0.9.7e, openssl 0.9.8a, w/o cyphering the keys....) and no success...
If I write a wrong path in the SER config file, the error that appears is "file not found" so I guess the location of certs/keys is properly set. Even in the log the path is right....
I would say is a parsing problem because if I modify the cert itself the error that appear in the SER log is different (I have really tried lots of "strange" things...). If I modify the data, base64 error, if I add a blank line between CERTIFICATE BEGIN and the cert itself it complains about "no end line found"....that is why I deducted there is a problem in the parsing but I ran out of time to continue with debuging :(
Can you please send me a working testing cert/key to try in my setup?
If your certs work with openser I think they should be fine.
Try to rename the certs and put them into the default location. (To find out the default location and name for the certs just start TLS withouth cert configuration and watch the logs.

Than you,

2006/4/11, Klaus Darilion klaus.mailinglists@pernau.at:
Are you using the simple configuration (in ser.cfg) or the advanced version (in a separate configuration file)?
Maybe there are bugs in the configuration part of TLS.
I tried once the external configuration file and it worked as long as I only used the default domains. Specifying dedicated TLS domain failed due to parser bugs.

Last check I made was to verify my own generated CA and server certs/keys with latest openser-1.0.1.-tls and it properly reads the files. I deducted therefore that there must be something wrong in the cert reading process in the SER's tls module. I can not debug further due to lack of time but I hope to read some mail providing some feedback... it might also been some misconfiguration in my config but I took it from the latest mails Jan sent to the mailing list regarding TLS configuration (see the first mail on this thread for the config file).
Thanks, Samuel.

Last call for help....I'll detail steps to see if some guru finds what I am not doing right:
I have created the cert/key in the PEM format with the next commands: Create self CA: #openssl req -newkey rsa:2048 -keyout CA98key.pem -new -x509 -days 365 -out CA98cert.pem -outform PEM Create the request for our domain: #openssl req -newkey rsa:2048 -keyout ser98key.pem -new -days 365 -out ser98req.pem -outform PEM Sing&issue cert #openssl x509 -days 180 -CA CA98cert.pem -CAkey CA98key.pem -req -CAcreateserial -CAserial ca.stl -in ser98req.pem -out ser98cert.pem
The 98 comes from the openssl 0.9.8a (I upgraded from 0.9.7e after several "lost" hours...)
I can check with openssl tools the cert and key and both are OK and can create connections using the s_server and s_client tools included in the openssl package. They have the appropriate format, certificate file:
-----BEGIN CERTIFICATE----- askjdfl -----END CERTIFICATE-----
and the key: -----BEGIN RSA PRIVATE KEY----- Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,8B980883B8F1BADF
-----END RSA PRIVATE KEY-----
I have checked for "strange" characters but everything seems ok except that when I start SER, it gives me:
Apr 10 17:55:47 serTLS ser[6741]: ERROR: tls/tls_domain.c:200: TLSc<default>: Unable to load certificate file '/usr/local/etc/ser/certs/ser98cert.pem' Apr 10 17:55:47 serTLS ser[6741]: ERROR: tls/tls_domain.c:201: load_cert:error:0906D06C:PEM routines:PEM_read_bio:no start line Apr 10 17:55:47 serTLS ser[6741]: init_mod(): Error while initializing module tls
Any feedback is highly appreciated...I never thought it would so difficult to use TLS.....

I have been able to create a TLS connection with openssl tools (s_server and s_client) using the certificates that SER is unable to open. Can anyone tell me how can I debug this problem and find where the problem is?
Thanks again, samuell.
2006/4/7, samuel samu60@gmail.com:
It starts with Certificate and the corresponding fields. After this information, the cert itself begins with the BEGIN statement.
As I said, I am just starting with TLS and probably I did not create the cert properly. I'll try to read more information meanwhile.
Thanks, Samuel.
