[ns] Problem with installing nam using Cygwin/X

[Alex Hoffer]

Hi there,

I have recently installed ns from the 2.30 allinone package.  I have
successfully compiled it in Cygwin/X, and passes most of the
validation tests except for the ones that are documented.  However, I
cannot get nam to run at all.  Instead, once it runs it gets
configured and made, and I try to run it in an X window, it crashes
exits:

nam:
[code omitted because of length]
: no files matched glob pattern "~"
while executing
"glob ~"
invoked from within
"lindex [glob ~] 0"
invoked from within
"AnimControl set PORT_FILE_ "[lindex [glob ~] 0]/.nam-port"

In the Cygwin terminal, I get the messages:

winMultiWindowsXMsgProcErrorHan
dler - ERROR: BadWindow 
winMultiWindowsXMsgProcErrorHandler - ERROR: BadWindow 

Here are my environment variables that I have set, grabbed from my
/etc/profile file:

PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/ns-
allinone-2.30/bin:/ns-allinone-2.30/tcl8.4.13/unix:/ns-allinone-2.30/tk8.4.13/unix:/:$PATH
LD_LIBRARY_PATH=/ns-allinone-2.30/otcl-1.12:/ns-allinone-2.30/lib
TCL_LIBRARY=/ns-allinone-2.30/tcl8.4.13/library

Output of uname -a is
CYGWIN_NT-5.2 TBDEVCOOP 1.5.24(0.156/4/2) 2007-01-31 10:57 i686 Cygwin

What do I do to fix this error?  It appears to be looking for
something in my home directory, but I have no idea otherwise why it
won't work.  Any help would be nice, thanks!

[ns] Priority Packet Simulation Debug

[romzyi prasetyo]

Dear All

I am newbie in NS2. Currently I am doing priority packet simulation. I
simulated 4 nodes n0,n1,n1,n4.
The situation like this:

n0 (tcp agent)
\
 \
  n2---n3(sink)
/ (router)
  /
n1 (tcp agent)

I assigned priority 0 to node n0 and priority 1 to node n1. Then using
simple priority queue algorithm used to dequeue packets sent by node n0 and
n1 to node n3.However, after the simulation completed,when I looked at the
trace file, the node n1 is not generating any packet. Therefore  I can not
compare the throughput from node n0 and node n1 because node n1 is not
generating any packets. I've spent three nights to debug this error but I
couldnt figure it out yet. Is there anyone that understand the problem and
have experiences in this kind of error?
I'll appreciate your help very much.

[ns] Queue-monitor problem (BUG?), Departures more than Arrivals

[Khurram Aziz]

Hi,

The tcl code is attached below. I am trying to simulate an M/M/1 queue for a
duration of 9000 seconds, and I want to reset the queue-monitor counters
after every 3000 seconds in order to obtain confidence intervals for
calculating mean queue lengths and waiting times.

The problem is that I am getting negative values for queue lengths (i.e.
parrivals_ - pdepartures_) after I reset the queue-monitor.

Any ideas why this is so. Am I missing something in my code?

Re: [ns] ns-allinone-2.26 installation problem - Plz Help

[roger juan huanca sevilla]

Hi

it's a compiler problem if you compile vith g++ 2.95 for example you can
do it but i don't know if you have more problems for the rest of the
packages in theory it's work well for linux versions like (RED HAT 7.2
...) why don't you try to install ns -2.30 it's work without problems.

Pd.: if comeone knows how to solve the proble using the patch, tell us.
