[ns] How to change node configuration when simulation is running?

[lukman_hanif@yahoo.com]

Hi simayeji,

I don't know about RXthreshold setting but usually people change the running simulation parameter  in Tcl  script by using the command like
$ns at 2.5 " put your Tcl configuration command here "
That's all I know to change some configuration in the running simulation...

Lukman

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

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. 
? 
Regards,?

ali balador,
