Delay Calculation From Trace Files Of AODV / LAR Protocols

when i am running delay.awk file on AODV.tr and LAR.tr For AODV.tr , it is giving me the o/p value as some delay
but for LAR , its showing me the follwing error

gawk: e2edelay.awk:93: (FILENAME=larscen5.tr FNR=36516130) fatal: division by zero attempted

I was unable to recify the error. could you please help me.
thank you so much

this is the code of awk file which i am using for calculation of delay. kindly help

How I Can Print A Specific Range Of Nubers Form A File.

hello,

i am trying to make a table from some files. i used this to record how much "RD_" field i have in my file. Quote:

forexample i got 5 "RD_" fields now i want to print 5 number of fields from another file starting from 2nd field. i did it mannully like Quote:

Python Ftplib

hello all,

please help me with python ftplib. i was trying to copy files from my linux machine to a windows server using ftplib. everything was working good. but i'm only able to copy files from the same directory the script is. how do i copy files from a different directory? i always get "file not found error message". here's my code :

Code:

tester_name = str (socket.gethostname())
def upload(ftp, file):
    ext = os.path.splitext(file)[1]
    if ext in (".txt", ".htm", ".html"):
        ftp.storlines("STOR " + file, open(file))
    else:
        ftp.storbinary("STOR " + file, open(file, "rb"), 1024)



parse_source_path = ('/path/to/where/i/go/')
parse_source_file_list = os.listdir(parse_source_path)

ftp = ftplib.FTP("server_IP")
ftp.login("username", "pass")

folder_list = []

ftp.dir(folder_list.append)

if str(tester_name) not in str(folder_list) :
    ftp.mkd("%s"%tester_name)
    ftp.cwd("%s"%tester_name)
    for files in parse_source_file_list :
        print files
        upload(ftp, files)


else :
    print "later"

Help With Applying Passing Parameters

i need to complete this exercise but my code has some issues
HERE is the PRoblem:
Create a script that can accept ANY amount of numbers from the command line. Process the numbers one at a time, where numbers greater than 10 print �large�, numbers less than or equal to 10 print �small�
E.g. process 5 10 15 would print
small
small
large

and here is my code so far
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi
if [ $@ -le "10" ]
then
echo "smaller"
else
echo "bigger"
shift
fi

any help would be greatly appreciated

Extract Info And Find/count Strings From Blocks Inside Text File

Hello

I have a text file which has blocks like
Code:

dir1/dir2/dir3/name_run_number1:
line1_run_number1_part1
line2_run_number1_part2
line3_run_number1_part3...

Each block is separated with a blank line and there is the ":" in the "header" of each one while each block carries the same "number1" after "run_" suffix
What I want to do is for each block, extract the "number1" as shown in the first line and then for the lines below count from 1-20 and give a message if a "partX" line is missing. Any bash or python would be fine

Thanks

Grayhole Attack In Ns2 Using Aodv Protocol

Rsync, Reliable "copy And Paste" Type Of Backup In Case Things Break?

What I did in windows was create images of my drive and restore them.

in linux I am running

Code:

rsync -aAXv --exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /path/to/backup/folder

and this creates a folder for me with all my files, and apparently saves meta data like permissions and paths...

Since I'm using arch and things break sometimes,I'm booted into a CLI with errors and cannot figure my way out since I'm a noob... would I be able to just delete my entire root and replace it with the rsync backup without a problem?

Check Empty Variable Without Comments

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.
