There is currently no patch for ns-2.33 and since Eurane is not supported anymore, there probably never will be. You have two options. 1) Download ns-2.30 and patch with existing eurane patch. If you need something introduced in later versions of ns-2, you cannot use it. 2) Patch an existing ns-2.33 with the eurane patch for ns-2.30. This could result in difficulties which you must manually resolve. The patching procedure is documented in the manual, section 2.3. A patch is distributed in something called a diff-file, hence the file extension .diff. Gzip then adds the extension .gz. Before pathing the .diff.gz file needs to be uncompressed using gunzip. The result will be the diff-file. > Anyway, when I download and open eurane1.12.diff.gz, it gives an > error "associated help application does not exist"! This patch is > available for NS-2.30, I am using 2.33. What gives an error? A patch file should not be "opened", see the eurane manual for correct usage, or the patch man page, or google for "unix command patch" or similar. > Also, what is CLEAN NS-2.3 A clean version is a version not messed up by changes, builds etc. A fresh downloaded version is a clean version. > I downloaded test_tcp.tcl (UMTS implementation on NS-2 test run), > without installing any patch on my existing NS-2.33.

You need the patch to be able to run the tcl files. Regards, -- Mats Folke, M.Sc., Lic.Eng. Research Engineer Ericsson AB Office: +46 10 7171385 Ericsson Research Fax: +46 920 99621 P.O.
