Several things are wrong with this:

1. DO NOT EVER USE TELNET.
Seriously. Don't do this. It sends your user/pass in plain text. It's
a horrendous security risk. I don't care what excuse you have to try
to defend it. DO NOT DO IT. Use ssh keys instead.

2. Use ssh keys instead of setting a password in the script.

3. You don't need to use expect to set the PWD to /tmp. You can do
this with basic scripting. Pick up a bash scripting guide and read
through it. I see almost nothing in your example that requires expect.
This can be done with a simple bash script.
