When you connect using PuTTY, are you just putting the details in and connecting, or are you using some saved session?

It could be that the saved session has the hop saved in as a command to execute on login to serverA. If it is a saved session, load it but don't initiate the connection, and go to the SSH Tab/Category. There is an entry there where you can specify a remote command such as that required to ssh from ServerA to ServerB, so you automatically get forwarded from ServerA to ServerB when you login to ServerA using the saved PuTTY profile.

I think you can direct Plink to use the same profiles, but I'm not 100% certain of that. You could look at the PuTTY documentation to see the details. PuTTY User Manual

If this is the case, we just need to figure out how to get the script from the Windows box to ServerB, this could probably be done using 2 separate scp commands within a single script.

I just tested this and if you have a saved session in PuTTY, you can use the same session in plink

Code:

plink -load <<session-name>>

If the session name has a space in it, you can put it into double quotes.

I also checked if a saved session has a "ssh user@anotherhost" command saved in the SSH category, it will lok like it directly logs into anotherhost without an internediate shell, and you should just be asked for the password for 'server' first, and then for 'anotherserver'. The good news is this works exactly the same if this session is then used for a plink connection.

netrc

NETRC(5)						      BSD File Formats Manual							  NETRC(5)

NAME

     netrc -- user configuration for ftp

SYNOPSIS

     ~/.netrc

DESCRIPTION

     This file contains configuration and autologin information for the File Transfer Protocol client ftp(1).

     The .netrc file contains login and initialization information used by the auto-login process.  It resides in the user's home directory.  The
     following tokens are recognized; they may be separated by spaces, tabs, or new-lines:

     machine name
	       Identify a remote machine name.	The auto-login process searches the .netrc file for a machine token that matches the remote
	       machine specified on the ftp command line or as an open command argument.  Once a match is made, the subsequent .netrc tokens are
	       processed, stopping when the end of file is reached or another machine or a default token is encountered.

     default   This is the same as machine name except that default matches any name.  There can be only one default token, and it must be after
	       all machine tokens.  This is normally used as:

		     default login anonymous password user@site

	       thereby giving the user automatic anonymous ftp login to machines not specified in .netrc.  This can be overridden by using the -n
	       flag to disable auto-login.

     login name
	       Identify a user on the remote machine.  If this token is present, the auto-login process will initiate a login using the specified
	       name.

     password string
	       Supply a password.  If this token is present, the auto-login process will supply the specified string if the remote server requires
	       a password as part of the login process.  Note that if this token is present in the .netrc file for any user other than anonymous,
	       ftp will abort the auto-login process if the .netrc is readable by anyone besides the user.

     account string
	       Supply an additional account password.  If this token is present, the auto-login process will supply the specified string if the
	       remote server requires an additional account password, or the auto-login process will initiate an ACCT command if it does not.

     macdef name
	       Define a macro.	This token functions like the ftp macdef command functions.  A macro is defined with the specified name; its con-
	       tents begin with the next .netrc line and continue until a null line (consecutive new-line characters) is encountered.  If a macro
	       named init is defined, it is automatically executed as the last step in the auto-login process.
