XGraph

Hi sir

I try to get a graph by using xgraph at ns2 , i want to show the loss paquet rate in graph .

i use a file awk to get it but when i try to execute "awk -f lpr.awk out.tr " an error message showen " syntax error " .

I want to know how can i get a graph using xgraph and awk code ?

Hi,

Whenever I run xgraph command, the output is
[1] 6177
For 2nd instance, the output is
[2] 6179
[1] Segmentation fault (core dumped)
and so on.
The command which I have used is "exec xgraph Throughput &"

If i use command "xgraph Throughput &", I get
Segmentation fault (core dumped)

I am unable to get the graph.
Please help me!!!

hello sir,
please help me in generating xgraph. when i type xgraph I get an error message "Command not found" or "Nothing to plot" though I have installed xgraph.I use NS 2.34.

What to do if this line appears in the Xgraph

Parameter LabelFont: can't translate `helvetica-10' into a font (defaulting to `fixed )

I am currently doing my project in NS2. i need to analyze my tracefile with xgraph. so i am in need of AWK scripts that are used to generate xgraph(eg:Time vs Throughput). Can any one pls help me??

Hi,

i wana implement the watchdog & pathrater on AODV protocol in MANETS for misbehaving nodes on NS2.35. I wana show its performance analysis via xgraph. I have added a malicious node on AODV protocol after that i couldnt figure out how can i implement watchdog and pathrater and show analysis via xgraph. I have chcked the similar threads here but it was for ns 2.34 but still i tried it and m getting errors. I downloaded the watchdog zip files and followed the instructions of text file of it. One more thing, is it necessary to set all nodes for promiscuous mode??I also need code for that. I put the watchdog-basic.zip folder in AODV folder which was inside of ns-2.35 but what should be the tcl script for watch dog i have aodv tcl file in which malicious node is added too. I am new to ns2 and linux. Please help anyone i urgently need answers.

Hi
i ve installed ns2.35 in ubantu14.04,
i hav successfully run tcl script, bt when i've tried to execute nam command, it gave me " Segmentation fault (core dump)" .
although i can sucessfully run awk & Xgraph commands, bt unable to run nam
plz help me out...

Hello guys! 
Does anyone have a solution to trace graph windows not loading properly. I am using ubuntu 14.10 and when i run something like "paulchiedo@paulchiedo-virtual-machine:~/Documents/tracegraph202$ ./trgraph /home/paulchiedo/mobilesense.tcl" I get "ERROR: No data! choose another time interval" on the terminal. The three trace file windows open but the problem is that for the "Graph's" window only the -file, -options on the menu bar is highlighted. For the "Trace garph 2.02" window -file, - Options menus are highlighted but no data apears and finally for the "Network Information" window only -Options on the menu tab is highlited.


* It is however noteworthy that this problem did not start from the point of installation as the trace graph had worked fine prior to this problem..

I would really appreciate it if someone would be so nice to help me through this problem. Thank you in advance! 

following error shown when i tried the command:
cd ns-allinone-2.27/ &&export CC=gcc41 CXX=g++41 && ./install

please help

I am trying to write a script to create a variable (string) out of specific lines from another file. The string will be used as headings for lists in another script. My plan is to create a variable "myvar" with the output from an awk command run against a file called banners.txt then I can call $myvar whenever it is appropriate in the larger script. additionally I can add/modify the banner file instead of having to comb through a large script to add or change echo commands.
So, here is my proof of concept script:
Code:

#!/bin/bash

path=/home/rstenger/

TESTFILE=$(<banners.txt)
MYVAR=$( awk 'NR > 6 && NR < 10' "$TESTFILE" )
#
echo ""
echo ""
echo $MYVAR
#
for i in {1..5}; do echo ""; done
echo $TESTFILE

exit

which produces this output:
Code:

sl7jump1~#->./test1.sh 
awk: cmd. line:2: fatal: cannot open file `******************************************************

What I was looking for is:
Code:

******************************************************
*                3rd banner has 3 line               *
******************************************************

I am very puzzled as to why I get the contents of the file in the awk error message, and the contents of my home directory as the variable.

Thanks,
Robert
