Hi all,

I am trying to simulate leach on NS2 but I've had problems with running the leach_test. I've followed all steps from installing NS2 up to installing the LEACH patch (used the latest one from exidus). Here's the error message in the leach.err I found.

Code:

    while executing

Your help are very much appreciated, thanks!

Hello guys. When ever i tried to run CRCN protocol i am getting following error:
harsh@ubuntu:~/ns3/test$ ns test1.tcl
num_nodes is set 10
missing operator at _@_
in expression "$i < $val(ni) _@_$val(channum) "
(parsing expression "$i < $val(ni) $val(cha...")
invoked from within

$ns_ add-channel $i $chan_($i)
}"
(file "test1.tcl" line 48)

Can someone guide me how to correct this error??

Thank you

Hello,

They gave me this:
Code:

#!/bin/bash

# Write error message on stderr and die
function die() {
  echo "$@" >&2
  exit 1
}

# Load var from properties files
function load() {
  for propertie in "$@" ; do
    [[ -f "${propertie}" ]] || die "load() : \"${propertie}\" don't exist !"
    while read ; do
echo "${REPLY%=*}"
echo "${REPLY#*=}"
      [[ -n "${REPLY%%=*}" && -z "${REPLY#*=}" ]] || die "load() : Variable \"${REPLY%%=*}\" is empty!"
      eval "${REPLY%%=*}"=\'"${REPLY#*=}"\'
    done < "${propertie}"
  done
}

load "manage_srcds.conf"
echo "SRCDS_TICKRATE=$SRCDS_TICKRATE"
echo "SRCDS_SCREEN=$SRCDS_SCREEN"
echo "SRCDS_SRCDS_GAME_NAME=$SRCDS_GAME_NAME"
echo "SRCDS_MAXPLAYERS=$SRCDS_MAXPLAYERS"

but, return:
Quote:
###################################################
###################################################
load() : Variable "###################################################" is empty!

cat manage_srcds.conf

I just wish that there was no empty variable excluding those who do not have integer.

Best regards,

Hi all ,
I have a requirement where I have a file. Contents of the file are :
#comments
VAR="abg"
RES=123
#comments
IC6790ABG="https://www.abc.com"
IC5678-vg="https://www.bhy.com"
IC-gy_567:78="https://www.gyt.com"
#comments
The variable names can not have characters like - , : so
in this file I have to find words starting with IC and replace characters like - ,:
I want to change only the variable name , not the whole line.
I have used SED command

sed -i '/^IC/s/[^0-9 a-z A-Z _]*//g' file

when I am using this command , it is replacing the whole line
output becomes :

#comments
VAR="abg"
RES=123
#comments
IC6790ABGhttpswwwabccom
IC5678vghttpswwwbhycom
ICgy56778httpswwwgytcom
#comments


But I want the output like this :

#comments
VAR="abg"
RES=123
#comments
IC6790ABG="https://www.abc.com"
IC5678vg="https://www.bhy.com"
ICgy_56778="https://www.gyt.com"
#comments

How can I get the desired output , thanks for your help in advance .

Hi all,

I am trying to write a script that syncs files from source to destination. I have one centralized server that can ssh to any servers without pw. Now when I run the script, it can ssh to source server perfectly fine, but you need to enter password for destination server. Was wondering how I can clean this up before I start using case statements

Below is a sample I wrote

#!/bin/bash

#This scripts syncs shit

echo "Type in ID: "
read ID

echo "Type in Server : " #source server
read S

echo "Type in Destination Server: "
read DS

if [ $S == 9 ]; then
ssh -t "root@"$S"webserver1" "rsync -av /home/rlui/"$ID "root@"$DS"webserver2:/home/rlui/";
ssh -t "root@"$S"webserver1" "rsync -av /home/rlui/tmp/"$ID "root@sl"$DS"webserver2:/home/rlui/tmp/"
exit 1

where S and DS are cluster numbers

I apologize in advance if I am not clear on anything
