Hi,

I am planning to have the below Test systems with TITAN installed:

Windows-System1: TItan Installed on Cygwin Acting like DNS Client
Ubuntu-System2: Titan Installed Acting like DNS Server

Test Scenario is attached.

For this I am planning to use the following:

Protocol Module: DNS
Test Port(Transport Layer): TCP

I have created the attached Abstract Test suite DNSClient.ttcn & DNSClient.cfg.

In the same folder I have copied the below files:

TCPasp_PT.hh
TCPasp_PT.cc
DNS_EncDec.cc

Executed the below command to generate Make file:

$ ttcn3_makefilegen -gs DNSClient.ttcn TCPasp_PT.cc DNSClient.cfg
Generating Makefile skeleton...
Makefile skeleton was generated.

When I run command "make dep", I am getting below error:

$ make dep
/home/eirmnp/software/titan/bin/compiler -L DNSClient.ttcn - DNSClient.ttcn
Notify: Parsing TTCN-3 module `DNSClient.ttcn'...
DNSClient.ttcn:17.9-12: error: at or before token `type': syntax error, unexpected TypeDefKeyword, expecting Identifier
DNSClient.ttcn:30.26-29: error: at or before token `runs': syntax error, unexpected RunsKeyword, expecting '('
Notify: Errors found in the input module. Code will not be generated.
Creating dependency file for TCPasp_PT.cc
In file included from TCPasp_PT.cc:34:0:
TCPasp_PT.hh:33:27: fatal error: TCPasp_Types.hh: No such file or directory
compilation terminated.
make: *** No rule to make target 'compile', needed by 'DNSClient.cc'. Stop.

But when I check the link: https://github.com/eclipse/titan.TestPorts.TCPasp/tree/master/src

I am not able to find the TCPasp_Types.hh.

Could you please help me how to get this file? & Is the procedure followed by me to create a test case is correct?

I have attached all files used for this activity.

Thanks in advance.

Regards,
Ramakrishna

Hi Ramakrishna,

first of all, are you certain you want to use TCP? DNS communicates over TCP rarely, only in case of long messages if I remember correctly; for ordinary queries, UDP should be used.
secondly, I don't see your Makefile in the package you have attached;

please do a 'make archive' ; this should create a package with all files plus Makefile, and attach it to your response.

Hi Elemer,

Thanks for the quick response. First I thought of using Transport Layer as TCP. If it works I thought of using Test port UDP.

Please find the make archive attached.

Hi Ramakrishna,

Please also note, that your TTCN-3 file is truly erroneous.
In the structure:
"
type record DNSQuery{
QNAME domainName,
QTYPE type,
QCLASS class
}
"
it is not allowed to use "type" as a field name ... as it is a keyword in TTCN-3.

Best Regards
Kristof

Hi Kristof,

Thanks for pointing the mistake. I will change "type" to "messageType".

Hi Ramakrishna,

you are also missing files from the DNS protocol module and TCP test port :

DNS_Types.ttcn

and TCPasp_PortType.ttcn and TCPasp_Types.ttcn.

Please read the attached documentation carefully.

Also , you are trying to send a type on the port; I believe you should start with the language standard first as without understanding the basics it's unlikely you will get very far.
We have also published some training material.

I believe you should also go through this forum and download some of the sample projects we have published in the beginning and compile/execute them .
This will help you understand how a Titan project works.

Best regards

Hi Elemer,

My understanding after reading the userguide was to keep *.cc & *.hh files only for the make file generation. It was my mistake. Now I have copied all the
Testport & Protocol modules src folder files to my project folder.

Also I have fixed now some of the issues related to DNSClient.ttcn. Now make dep shows some other errors. I am trying to understand the Example & Demo to give correct type port definitions in the DNSClient.ttcn.

Please find the latest make archive attached.

Regards,
Ramakrishna

Hi Elemer,

I started reading the core Language Standard, Titan documentation & examples to understand how the Titan Project works. After this only I started creating the Test suite files. I will refer different examples & understand how testports & protocols are used.

Thanks for the support.

Ramakrishna

Hi Ramakrishna,

I suggest you proceed step by step:

-first compile the TCP ( or UDP ) test port separately
-do the same with the DNS protocol module
-if both compilations are successful, then put them together and compile them together
-lastly , add your own file and try to compile; all errors should refer now to your file; try to find the reason of error

The package you have sent me is still missing files.

Hi Elemer,

Now to start with a demo I have done the following:

https://github.com/eclipse/titan.ProtocolModules.DNS/tree/master/demo

From this demo, I have copied all the necessary src files from:

1. DNS Protocol
2. UDP Testport

Now when I run make dep, it is successfull:

$ make dep
/home/eirmnp/software/titan/bin/compiler -L DNS_Demo.ttcn DNS_Mapping.ttcn DNS_Types.ttcn UDPasp_PortType.ttcn UDPasp_Types.ttcn - DNS_Demo.ttcn DNS_Mapping.ttcn DNS_Types.ttcn UDPasp_PortType.ttcn UDPasp_Types.ttcn

Now a Executable was created.
But I am not able to understand how to run this:

$ ./DNS_Demo 10.111.47.253 9999
TTCN-3 Host Controller (parallel mode), version CRL 113 200/6 R1A
Connecting to MC failed. MC address: 10.111.47.253:9999 Connection refused

Could you please help. So that once it is run, I will run nslookup from another host. If it is successfull I will start looking into this example along with core language standard to improve my TTCN-3 knowledge.

Thanks in advance.

Ramakrishna
