DOS batch file: SSH connection, how to script to enter password when prompted?

Hi,
I need to create a batch file on a Windows 2000 box which connects to linux box running an ssh (and ftp) server and uploads files in continuous loop for testing our connection.

I'm using putty's pscp to connect to transfer the files over. The problem is there is no way to specify the password on the pscp commandline. So I need to simulate its entry in the batch file as I can't have the user entering it manually everytime. This batch file isn't meant to be secure so yes the actual password will be exposed in the batch file. How can I do this? Here's what I have so far:

:START
pscp -r C:\data userName@192.168.0.2:/home/userName/
REM enter password when prompted
GOTO START


Thanks for any help!

This .vbs script will do it for you, save the below script to .vbs, ammend your details for domain\username and password, and the file name of course. See below link to my previously accepted answer.

****************************************

Dim WshShell, scomputername
Set WshShell = WScript.CreateObject("WScript.Shell")
Set oNetwork = WScript.CreateObject( "WScript.Network" )

srunme = "runas /userName@192.168.0.2:/home/userName/ pscp -r C:\data"

WshShell.Run srunme
WScript.Sleep 500
WshShell.Sendkeys "password" & chr(13)

Or you can create certificates and use certificate authentication instead of password authentication.
See "man ssh-keygen" on your link box

create a key without a password. You can load this key in a batch it is still safer than a password included into a batch.

PuTTY 0.52 (and late)r have a -pw command line switch, a la:

pscp -pw password -r C:\data userName@192.168.0.2:/home/userName/

If that doesn;t work for you, try:

echo password | pscp -r C:\data userName@192.168.0.2:/home/userName/

Yeah, I wouldn't bother with a password. Just generate a unique key to thw workstation and have SSH go straight in. Lot simpler.

If cgwilder's last suggestion doesn't work, create a text file with the password in and run the command like this:

pscp -r C:\data userName@192.168.0.2:/home/userName/ <password.txt
