ns2 - some validation tests failed

shojaru · 06-11-2009, 06:14 AM

Dear all,

After many modifications, I managed to install ns2.28 , but some validation tests failed. I got the following message at the end of validation test:
validate overall report: some tests failed:
./test-all-simple ./test-all-tcp ./test-all-testReno ./test-all-newreno ./test-all-sack ./test-all-tcpOptions ./test-all-sack-full ./test-all-tcpVariants ./test-all-LimTransmit ./test-all-aimd ./test-all-greis ./test-all-rfc2581 ./test-all-sctp ./test-all-tcpHighspeed ./test-all-frto ./test-all-friendly ./test-all-srm ./test-all-realaudio ./test-all-ecn ./test-all-ecn-full ./test-all-quickstart ./test-all-hier-routing ./test-all-lan ./test-all-mcast ./test-all-vc ./test-all-mixmode ./test-all-red ./test-all-adaptive-red ./test-all-red-pd ./test-all-rio ./test-all-vq ./test-all-rem ./test-all-gk ./test-all-pi ./test-all-cbq ./test-all-schedule ./test-all-jobs ./test-all-intserv
to re-run a specific test, cd tcl/test; ./test-all-TEST-NAME
Notice that some tests in webcache will fail on freebsd when -O is turned on.
This is due to some event reordering, which will disappear when -g is turned on.

I have searched the mailing list for the problem, I found many mails about it, but no reply to the mails. Is it a very silly thing, that people don't bother to reply? I have no idea what to do now. I found something like reporting bug about this. I tried to run the test individually one after another, but that is too time consuming, it prompts for permission after every test and thus runs many test & opens a lot of xgraph window. The tests I run so far individually, agreed with the reference output.

Now I am wondering, should I report a bug about it, or should I hire a kid to run those failed 40 tests( which require hitting the ENTER key 1200 times,maybe ) , or what else should I do.

Thank you for your time and attention.

Hire a kid, I must admit that made me laugh.

With the number of tests it says have failed, it may be an idea to do a clean install again. Of course, try using the fix it suggests for BSD systems, see what happens then

Please tell, which Linux, you are using.
Linux, name, version ( like Ubuntu 9.04, Fedora 10 ...)

And you must have a very good reason to use ns-2.28 ?
The current version is 2.33 .

I am sorry. I use Ubuntu 9.04.

I have installed ns2.33 earlier,which doesn't contain the 802.11e mac.I want to simulate 802.11e network and then modify 802.11e, but the only one I have found so far is the 802.11e patch from TKN , which is applicable to ns2.28 only. I asked before some support person about the compatibility of the patch with ns2.33. But all that I have found is any patch is only applicable to the specific release it was created for. Other releases might not be compatible and no support is available for that purpose.

I am struggling with this thing for months, but no luck. I still could not manage to run 802.11e . I know this forum is not meant for ns2 problems, but I am asking questions after questions everywhere, but only this forum is responsive to the questions. I post questions in the hope that maybe some ns2 expert will see the question and be kind enough to reply.

I really do search a lot in Google and the forums before posting the questions, I only try to post when I cannot find the exact similar solution. I don't mean to violate any forum regulation, since this is the only place where I can get solution, if there is any.
I know I am posting too many threads, I am sorry about that.
