[ns] How to get pointer MyMac from tcl?
I need to create the direct communication beetwen MyAgent and MyMac. I use TclObject::lookup(argv[2]) in command of myAgent to access at pointer of Mac. But $opt(MyMac) from Tcl is รจ string and not a pointer. How to get pointer create in TclClass from Tcl Script?

Re: [ns] how to get node id in classifier
It is a normal node, not mobile node.
i know classifier is one part of node.
but classifier can't get the node id.
if i include node.h, it will show some error.
I think classifier is one part of node, so can't include it.
but how know, the processing classifier is in which node?
this is my problem.

I understand from your query that you want to know the current execution
mobile node , is it that write?
From the error message you get, means net_id variable not found(not
declare) so may be the data structure (procedure) you deal with node
identification does not handle , so I advice you to read the structure
more times, may the point will be clear.

thanks for your replay
it also show 'net_id' undeclared (first function)
error: (Each undeclared identifier is reported only once for each
function it appears in. )
2007/7/19, Mohammed Abu Hajar :
Try this:
printf(net_id = %d,net_id.getNSAddr_t());

when i use the code in classifier.cc
printf(net_id = %s,net_id.dump());
it show net_id undeclared.

through net_id.dump()
in other words use: printf(net_id = %s,net_id.dump());

hello,
i want to get node id in classifier.cc
i don't know how to get node id.
so i include node.h and write code (follow)
Node* tempnode;
int ttmp;
if (tempnode){
ttmp=tempnode-address();
ttmp=tempnode-nodeid();
}
but it had segmentation fault(core dumped).
i used gdb to trace it.
gdb show program received signal SIGILL, Illegal instruction
somebody can tell me how to get node id ?

[ns] Source Specific Multicast problem
I used the SSM extension model http://eden.dei.uc.pt/~tandre/ssm_extension/index.htm I found this have one problem. the receiver received multicast data, but the data willn't in agent's recv function (like LossMonitor::recv(...)) but it also have not any error. is somebody knew, where is the problem. -- View this message in context: http://www.nabble.com/Source-Specific-Multicast-problem-tf4121956.html#a11722633 Sent from the ns-users mailing list archive at Nabble.com.
[ns] Why NAM doesn't dispaly the packet dropped because of collision?
Hi all,
I've been doing wireless simulations these days. I want to show NAM to my
colleagues to help them to better know about how RTS/CTS reduce the chance
of collisions. But I found NAM doesn't display the packet dropped because of
collisions. Why? Here is a line of the trace file and the NAM trace file for
a packet dropped because of collision:
Trace File Info:
d -t 2.267517062 -Hs 2 -Hd -2 -Ni 2 -Nx 700.00 -Ny 200.00 -Nz 0.00 -Ne
-1.00 -Nl MAC -Nw COL -Ma 5fe -Md 2 -Ms 0 -Mt 0
NAM Trace File Info:
d -t 2.267517062 -s 2 -d -1 -p RTS -e 44 -c 2 -a 0 -i 0 -k MAC
Why doesn't NAM display this dropping action?
And to be specific, following is my TCL scripts.

[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
if they have a fix for your problem.
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?
regards,
