1. Is your Packet tracer really in /opt/pt? This is not a fixed location, i used it as an example. The directory is where the "packettracer" executable script is located after install or unpack.
2. Verify if the variable was actually exported:
Code:
echo $PTDIR
3.You can try using for example PT7HOME instead (i have this and it is working).
Code:
PT7HOME=/opt/pt

Yes, my packet tracer is really in /opt/pt.

This is the output when put in the comman line the new environment "cat /etc/environment" Even so java web start does not launch packet tracer

Code:
PT7HOME=/opt/pt
This is the file /etc/profile for you support me.

Code:
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ "`id -u`" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

if [ "$PS1" ]; then
if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then
# The file bash.bashrc already sets the default PS1.
# PS1='\h:\w\$ '
if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
else
if [ "`id -u`" -eq 0 ]; then
PS1='# '
else
PS1='$ '
fi
fi
fi

if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
PT7HOME=/opt/pt
export PT7HOME
Saludos!

If it works, but it is not the most automatic in that way.

I would like the process to be more automatic.

Saludos!

Well it's weird. Where does your "javaws" come from (which package)? I suppose for some reason your environment does not pass the variable. What DE do you use?

Angry I want to delete all that I followed here.

Actually the packet tracer is not working as it is supposed to be. So whatever I followed here to install and run packet tracer can someone help me to take me back and remove all of it. I would really appreciate. It got me confused and I'm still a newbie. I tried to use apt command to remove but it says can't locate the package.

Here is a picture of what's going on :

1. Packet Tracer is not installed via the APT package system so apt commands will not work. It was installed separately by (i assume) the script provided by cisco. The installation script copies packet tracer in the directory you specify (i assume /opt/pt). I dont see any uninstaller, you just remove the folder altogether (btw which does not do anything else than sitting there).
Also look at the /etc/environment file and remove the packet tracer references there.

2. Did you declared LD_PRELOAD system-wide? Why? It is only supposed to be used for the specific command that NEEDS preloaded specific libraries.

Unhappy

I can't remove the folder.
Also how can I identify the packet tracer references in /etc/environment.

2. LD_PRELOAD! How can I fix this?As I told you I'm new to linux I have not understood it very well yet!

Um. Just delete everything from it. Then reboot.

Somehow you put in this file everything you need to put into the "packettracer" executable.
As this is a file that is supposed to export variables in a variable="value" format, you may have some issues on your system.

Can you provide info on how to do that? I don't want to try it on my own as it might get messed up.
