TCP ASPs over TLS [message #1810152]

Hi Titan experts,

I have a project using titan.TestPorts.TCPasp for handling TCP connections and need to extend it to support TLS.

Is it possible to configure the TCP ASPs for using TLS, and has someone a simple example?

Thanks for any hint,
Olaf @ ETSI TF160

Note: The titan.TestPorts.TCPasp are in https://github.com/eclipse/titan.TestPorts.TCPasp.git.

Hi Olaf,

yes, it is perfectly possible,

see an example here:

Using TLS/DTLS with Titan test ports part1(TLS with the TCP test port )

I hope this helps

Wow, Elemer, it works!! Thanks!
It is impressing what Titan offers.

Attached the Client-Server project I used for testing to run on two different machines, see ReadMe.txt for more info.

Still I have a rather minor problem: My main project has many TCP ports some use TLS others not, some are used as server ports and some as client ports. The problem is that I can not compile all with #define AS_USE_SSL and can not set all in server_mode.
My way forward would be to extend the TCPasp_Types so that I can choose which ports should be configured to use TLS (possibly with different certificates?) and have two different versions of Abstract_Sockets, one supporting TLS the other being 'plain'. This seems for me a nasty solution (Holzhammermethode in German :-).

Do you have a better idea?

Thanks, again :-),
Olaf

Hi Olaf,

you should have no problem compiling a project with several TCP ports; that only adds the possibility, and not the obligation, to use SSL/TLS.

Each port instance can be separately parameterized for a specific behaviour; say you have two ports TCP_port1 and TCP_port2:


*.TCP_port1.socket_debugging := "Yes"
*.TCP_port1.server_mode := "No"
*.TCP_port1.use_connection_ASPs := "Yes"
*.TCP_port1.ssl_use_ssl := "Yes"


*.TCP_port2.socket_debugging := "Yes"
*.TCP_port2.server_mode := "Yes"
*.TCP_port2.use_connection_ASPs := "No"
*.TCP_port2.ssl_use_ssl := "No"

port1 will be used in client mode with SSL/TLS, while port2 will be used in server mode , w/o SSL/TLS.

The whole range of parameters is documented in

titan.TestPorts.TCPasp/doc/UG/TCP Socket Test Port for TTCN-3 Toolset with TITAN, Users Guide.adoc

I hope this clarifies it

Best regards

Elemer

Wow, Elemer!

I don't need to do anything, all is there.
And my MCPTT Tester should work now with IPsec for the IMS part and HTTPS over TLS for the HTTP signalling to the simulated MCPTT servers. That's great!

Thanks,
Olaf
