Hi Gurhan,

I used the STT Tool an year back.

Let me answer some of your queries:

 

Q1: Would SUT/NUT still run stt tool? If so, how?

A1: SUT/NUT will NOT run STT tool. If you want to run SUT/NUT as server or client, then you can use sctp_darn or sctp_test utilities.

    Otherwise, you can also develop your own application for server or client.     

 

I feel that most of the points are clear to you, but even then, let me share a brief on “how to use STT”.

 

Brief Explanation on How to Use STT:

1.  Hardware Requirement

 

2.  Software Requirement

SCTP Test Tool

ETSI SCTP Test Cases

Guile-config

 

3.  Installation at TN (Testing Node)

Change directory to <path>/stt-0.9.9d.tar.gz/

# ./configure

# make

# make install

 

4.  Configuration at TN

a) Remove sctp kernel module if any, using rmmod

b) Change directory to <path>/stt/sctp-tests

c) Configure the directory path in file stt.scm

                  (define dir "<path>/sctp/sctp-tests/")

d) Create a soft link using command: ln -s stt.scm ./.stt.scm

e) Change HOME directory using command: export HOME=`pwd`

f) Depending upon the test case requirements, configure following fields of file “sctp-tests/sctp-param-testtool.scm”

      sut-is-server, sut-addr, sut-addr1 (add this variable for multihoming), tester-addr-1, tester-addr-2(add for multihoming),

      tester-port, tester-os, tester-mis

 

5.  Installation

a)  At NUT: Start SCTP Server or Client using lksctp tool or own application b)  At TN : Change directory to <path>/stt/sctp-tests c)  At TN : Execute following command-

#runsctptest <test case id>

d)  For example, #runsctptest sctp-d-v-8-1

 

The above explanation may clear some of your doubts.

There are lot of wise people in the mailing list, probably they can add something more to it.

 

Best Regards,

Arif

Subject: [SCTP-Discussion] Running the stt testtool.

 

Hi there,

I am having hardtime understanding how to set up a testbed for sctp

testing using stt tool. I have looked at the mailing list archives,

and I understand that I can have two nodes and designate one has SUT

which will have SCTP-enabled kernel and another one that can just be

used as a packet generator ( stt ) .

However, I am confused as to what to in the SUT node.. Would SUT still

run stt tool? If so, how? The webpage says "Furthermore the operating

system must NOT provide kernel SCTP support." ; so that made me think

that the SUT wouldn't be running stt. Is this correct?

 

On top of that, I understand that there sut can be defined as server

or client by toggling the sut-is-server variable false/true . Again,

if this is the case, would the testing node switch the roles

accordingly as well?

 

If the stt tool itself can be used in both SUT and testing nodes,

would they need to be sync up?

 

On a kind-of related note, I apparently at first downloaded the

older/non-working version of stt from

http://www.sctp.de/sctp-download.html page. It still has stt-0.9.6

version, whereas the newest version is at

http://sctp.fh-muenster.de/sctp-testtool.html . Can someone please

update the former page?

 

Thanks in advance.

Gurhan
