[ns] segmentation fault
Hello all,
I wrote a new agent. this agent has a command{} which receives 6 arguments. I
used the following line to pass the arguments to the command{}.

but when I ran tcl script, I received this error:
segmentation fault. i know segmentation fault usually stems from illegal
access to the memory but i don't know how i should solve it.
can anybody help me about this error?any kind of help.
Thanks in advance

[ns] ns2.29 installing problem
Hello everyone
I installed ns 2.31 without any problem on centos5. but I couldn't install ns
allinone 2.29 on it. i changed the version of linux to FC6 but can't install it
again and i receive the same error.
i received this error:
*checking system version (for dynamic loading)... ./configure: line
7624: syntax error near unexpected token ')'
./configure: line 7624: ' OSF*)'
tcl8.3.2 configuration failed! Exiting ...
Tcl is not part of the ns project. Please see www.Scriptics.com to see
if they have a fix for your problem.
and I received several solutions from ns-users:
1-
The problem lies in how bash 3.1.x and 4.x.x parse the configure file. This
will simply pass through bash 3.0.x and lower versions. So in order to make
things work changed the following lines
tcl: file tcl8.x.x/unix/tcl.m4.
tk: file tk8.x.x/unix/tcl.m4.
otcl: file otcl-1.x/configure.in.
to:
system=MP-RAS-`awk ' { print $3 } '/etc/.relid`
2-
modify file /home/nsuser/ns-allinone-2.29/nam-1.11/agent.h, on line
73,change the
character NULL to 0.
3-
I successfully installed ns-allinone-2.29.2 on FC5 but after
slightly modifying the whole package. First, I updated the Tcl and Tk
sources to the 8.4.13 (you can grab a copy from sf.net). Then you'll
have to modify the configure files (Tcl, Tk, OTcl and TclCL) in this
way:
cp -v configure{,.orig}
sed s/relid'/relid/ configure.orig configure
i tried above solutions but again i received the same error
and now i don't now how to solve this.
can anybody help me?

[ns] video conference PLR
Dear ns-users, here I want to thank everyone that help me till now in my project.my thesis is progressing.( it is about call admission control in diffserv ) now again i have some questions and i hope that you answer to me. 1- what kind of traffic is used for video conference in ns. for example for VOIP we use from Exponential traffic. i guess that i should use from trace files of real traffic. what's yr idea? 2-for VOIP traffic i calculated PLR but in xgraph, i saw strange behavior. PLR reaches to 48% and suddenly decreases to -48% and gradually again increases to 18% and this behavior repeats with different PLR. i can't understand why. and also PLR is very high. is it normal? please kindly answer to me. Thank you in advance. Best regards, Elahe - Ready for the edge of your seat? Check out tonight's top picks on Yahoo! TV.

[ns] ns 2.2x installing problem
Hello everyone
I installed ns 2.31 without any problem on centos5. but now I have a problem on
installing ns allinone 2.28.
At first i received this error:
*checking system version (for dynamic loading)... ./configure: line
7624: syntax error near unexpected token ')'
./configure: line 7624: ' OSF*)'
tcl8.3.2 configuration failed! Exiting ...
Tcl is not part of the ns project. Please see www.Scriptics.com to see

and I found a solution in Internet:
The problem lies in how bash 3.1.x and 4.x.x parse the configure file. This
will simply pass through bash 3.0.x and lower versions. So in order to make
things work changed the following lines
tcl: file tcl8.x.x/unix/tcl.m4.
tk: file tk8.x.x/unix/tcl.m4.
otcl: file otcl-1.x/configure.in.
to:
system=MP-RAS-`awk ' { print $3 } '/etc/.relid`
Now after changing the configuration files you will have
to delete older configure file and any cache if it exists in the respective
folders. After that do not forget to run autoconf from command line in the
respective folders to generate a fresh configure file.
i change the three above files then i run autoconf (without deleting any
configuration file!)
[EMAIL PROTECTED] unix]# autoconf
and i saw this error:
configure.in:199: error: do not use LIBOBJS directly, use AC_LIBOBJ (see
section `AC_LIBOBJ vs LIBOBJS' If this token and others are legitimate, please
use m4_pattern_allow. See the Autoconf documentation.
and now i don't now how to solve this.
can anybody help me?
