    Sir, my ubuntu version is 12.10 and i need to install gcc-4.3 in it..where can i get it? when i tried the command sudo apt-get install gcc-4.3 i am getting the following error

    sudo apt-get install gcc-4.3
    [sudo] password for linta jose:
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    Package gcc-4.3 is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source

    Can u help me?

      First try dese commands
      --------------------------------------
      sudo apt-get update ( means you need to keep your pc updated )
      sudo apt-get install build-essential autoconf automake libxmu-dev

      To Download Gcc-4.7 (replace 4.3 for your requirement) on ubantu12.10

      commands
      ----------------
      sudo add-apt-repository ppa:ubuntu-toolchain-r/test
      sudo apt-get update
      sudo apt-get install gcc-4.7



      If these doesn't work well , you can manually try to install it ,please get the version from this link http://packages.ubuntu.com/hardy/devel/gcc


      Worst case if you got irritated , you can shift to cygwin in windows and install ns-2

      Ns-2 needs list of packages which helps it to run . among them gcc compiler,perl, etc... .These packages are independent of NS_2 allinone. so ,you need to install all packages required . you can directly use commands to install from net else you can download needed packages and install those.

      if you cygwin in windows , it comes up with packages then you have to select those needed one's

      it means ns allinone alone cant install ns on ubuntu 12.10?
      we should have internet for installation.
      thanks for positively replying!

      Thanks alot sir!
      I read your post about black hole attack!
      In my tcl script I have done following
      ....
      set val(nn) 30 ;# 30th Node is BlackHole Node
      set val(nnaodv) 29 ;# number of AODV mobilenodes...
      ..
      # Creating blackhole nodes for simulation
      $ns node-config -adhocRouting blackholeaodv
      for {set i $val(nnaodv)} {$i < $val(nnaodv)} {incr i} {
      set node($i) [$ns node]....
      hope this is right.....

    Remove the ns 2 folder where u installed. I think u might install ns-allinone . So , please search for that folder and delete .again try installing ns2 to any of ur desired drive. U can install 2 also , if there in diff drives

      AODV is wireless adhoc routing protocol. it does not posses links . if the link failure happens . its uses djistra's algorithm to transmit data in another possible way. please clarify urself what has to be implemented.

    Please download aodv tcl from AODV tcl downloads page and try to simulte it . Before that you need to install Ns-2 , if it installed correctly when u enter $ns it should give % symbol . use termianl and run the command

    ns aodv.tcl --> this will generate the trace file to the location u set in the tcl file. later you can analyze and generate graph.

    sir,
    i need urgent help.
    how to delay a packet using tcl script.
    because of sudden delay ACK is received after RTO expires.
    so, the sender retransmit the missing packet(without loss). here, retransmission is unnecessary.
    please help.
