PacketTracer5.3只有32位的，而且提供的软件是bin文件。以下提供如何在ubuntu 64位下安装
方法是：
安装的时候提取出packettracer的deb文件，然后装好32位库文件，再强制安装packettracer即可
1、下载packettracer5.3
下载地址我忘了，有需要的可以留言。
2、建sh脚本：PacketTracerx64Hack.sh
#!/bin/bash

# the unsupported 64-bit Ubuntu or Debian Linux platforms
echo “Installing Required Libraries”
apt-get -y install ia32-libs-gtk
echo “ia32-libs-gtk is the key to the installation. Without it, PacketTracer will not work.”
echo “.deb file exists in /tmp”
echo “ “
echo “copying installer to ./“
echo “ “
cp -v /tmp/selfextract.*/Packet* ./
echo “Copy Successful”

echo “Installing Libraries”
wget -c http://content.kaslit.com/downloads/getlibs-all.deb
dpkg -i getlibs-all.deb
echo “ “
echo “Running dpkg -i –force-architecture Packet*.deb”
dpkg -i –force-architecture Packet*.deb
echo “ “
echo “PacketTracer is installed”
echo “ “
echo “Applying libs”
getlibs /usr/local/PacketTracer5/bin/PacketTracer5
echo “ “
echo “PacketTracer should now be installed - However, this script is light and does not detect errors.”
echo “ “
echo “Running PacketTracer”
echo “ “
echo “Did PacketTracer Not Install? If not, look for the ia32-libs-gtk file in the Debian/Ubuntu repositories. It is the key to the successful install.” > ~/PacketTracer_README_IF_IT_FAILED.txt
/usr/local/PacketTracer5/packettracer
3、安装
sudo sh PacketTracer53*
点阅读说明，阅读到90%的时候，另开一个终端
sudo sh PacketTracerx64Hack.sh
该脚本会自动复制packettracer的deb文件，并自动安装
