Putty automatic connection script

Question

I created a script to connect automatically to my Raspberry using putty :

start /D "C:\Program Files\PuTTY\" putty.exe -ssh 192.168.1.104 -l pi -pw mypassword

But it doesn't load properly, it does use the pi username but I get an access denied for the password it then asks me for another password as you can see :

Using username "pi".
Access denied
pi@192.168.1.104's password:

When I type the exact same password it let me access the Raspberry.

Do you know what I did wrong ? Thanks in advance !

This works fine on my machine. Are you using any special characters in you password?

Try using quotation marks at your password in the script.

start /D "C:\Program Files\PuTTY\" putty.exe -ssh 192.168.1.104 -l pi -pw "mypassword"

Some characters in Windows command line have specific meaning i.e. @, $, !, %, =, \, so you could easily output another string as password argument, or form an escape sequence.

For example, %0-%9 would output arguments no. 0 - no. 9 passed to the batch script file, %cd% would print current path.

Here is a table of escape sequences used in Windows batch script files.

+-------------------------+-----------------+ | Character to be escaped | Escape Sequence | +-------------------------+-----------------+ | % | %% | | ^ | ^^ | | & | ^& | | < | ^< | | > | ^> | | | | ^| | | ' | ^' | | ` | ^` | | , | ^, | | ; | ^; | | = | ^= | | ( | ^( | | ) | ^) | | ! | ^^! | | " | "" | | \ | \\ | | [ | \[ | | ] | \] | | " | \" | | . | \. | | * | \* | | ? | \? | +-------------------------+-----------------+

Hope this helps.
