nam problem

[balador]

I have installed ns-2.33 on cygwin on xp.

while running simple example programs, I get error,

$ nam: no display name and no $DISPLAY environment variable.

 

I tried set it with export DSIPLAY=:0..0

it gives error  

$ nam: couldn't connect to display "0.0"

I also tried  startx before running programs, it gives following error,

$ nam:

[code omitted because of length]

: no event type or button # or keysym

   while executing

"bind Listbox <MouseWheel> {

%W yview scroll [expr {- (%D / 120) * 4}] units

}"

   invoked from within

"if {[tk windowingsystem] eq "classic" || [tk windowingsystem] eq "aqua"} {

bind Listbox <MouseWheel> {

%W yview scroll [expr {- (%D)}] units

}

bind Li..." 

can anybody figure out where the problem lies?

I am new to ns-2 as well as linux environment so please.....

 

Thanks in anticipation.

Hello all!
Does anyone know how I can use mobile ip with sctp at transport layer, in a wired-cum-wireless topology with hierarchical addresses?
The standard method doesn't work in this case; should I modify something???
I would be very grateful if you could help in any way,
Spyros

Hi All,

I am using ns-d veresion 2.33 on Redhat Entreprise server 5.0

I hav installed and vaildated this version. However, when trying to execute
the example1.tcl of the tutorial by Mark, I go the following error message:"
ns finish: couldn't execute "nam": no such file or directory
    while executing
"exec nam out.nam &"
    (procedure "finish" line 7)
    invoked from within
"finish"

After validating the installation, I got this message :"validate overall
report: all tests passed
But still, I am not able to go through with the first example1.tcl.
Any suggetions.

Hi,

The reason for getting this error is : Path is not set for NAM file.
What you need to do is set the path as:

 NAM=/root/Download/ns-allinone-2.33/nam-1.13/
PATH=$PATH:$NAM

You can also execute the nam simply by giving the nam path as exec
/root/Download/ns-allinone-2.33/nam-1.13/nam file.nam

Regards

Kiran

Hi Hakki.

I had the same problem with ns2.33 on Fedora 9,
there is some tk binding problem there...

What I did:
 Download the tk-8.4-lastevent.patch from ,
 http://bugs.gentoo.org/show_bug.cgi?id=225999

 place it in ur tk8.4.18 directory
 and go to the same directory and execute,
  patch -p0 < ./tk-8.4-lastevent.patch

then go back , cd ..

and do ,

./install

./configure

 make

./validate

It should solve the problem (it did for me :)! )

Regards,

Vineet Kumar
