auto input pwd while ssh

As ssh became my first choice for going over GFW, a auto connected ssh tunnel is badly required.

what i did for a long time is adding a application launcher whose property is set as "ssh -D port usr@host" to the panel. the tunnel will be established with one click and some pwd typing.

I googled and find EXPECT.

Step One:

$sudo apt-get install expect

Step Two:

$vim ssh //create a new script.

Step Three:

//Input in Vim

#!/usr/bin/expect

spwan ssh -D port usr@host;

expect "*password:";

send "pwd\r";

interact;

//{esc};:wq;{enter} to save the file.

Step Four:

$chmod +x ssh

Step Five:

./ssh

Now the script will connect to ssh server automatically without requiring the pwd.
