[ns] Re:Segmentation fault in Nortel's Diffserv Module

[Xiang <ns@cdnet.edu.cn>]

Hi,
Thank you for your help. But I can't find test-all-diffserv testsuit in
~ns/tcl/test/.  The diffserv module I am using is ns-release7 in
ns-allinone2.1b6,RHlinux 6.0.  I install Diffserv module followed Nortel's
directions(i.e. install.txt in ns-release7.tar.gz).  It seems the example tcl
script (such as ds-cbr-trtcm.tcl etc.) run with no problem.
How can I find where this problem occured?
BTW, How to use gdb in ns script?
Thanks again!
Xiang
