Error Windows Batch script for Unix commands

I wish to create a folder on a unix server B from my windows box using windows batch script.

Below is my windows batch script.

Code:
 
@ ECHO OFF
::Enter your Directory name:
echo Enter your Directory name:
set /p mydir=
plink user1@ServerA
mkdir %mydir%

At plink command i get logged on to ServerA and get auto ssh to Unix ServerB.

Post auto-login to ServerB the command [mkdir %mydir%] does not get executed on serverB from my Windows batch prompt. I have to manually type the mkdir command from my windows DOS shell inorder for the folder to be created on ServerB.

Can you help the mkdir command in my windows batch script to get auto executed on ServerB ?

This is to be expected. A script runs on a certain system. If you i.e. issue

Code:
cmd1
cmd2
cmd3

then you expect "cmd1" to get executed, then "cmd2", then "cmd3". "plink ..." is such a command and gets executed - and as soon as it terminates, then next command gets executed.

If you want to remotely execute the last command, remove it from the script. Then, depending on the functionality of this "plink" facility:

Put a parameter to the plink-command to instruct it to execute the command remotely. With "ssh" you can do that, even on Windows.

Put the necessary command into a script at the remote system. You'd still have to execute that script per hand or using the method above.

Install a "rexec" (remote exec) or "rsh" (remote shell) feature (or however this may be called in Windows, i have no idea), which is designed exactly for your purpose. Be advised that this is considered a security problem in most productive environments, which is why ssh has an analogous facility built in. That does the same but in a more secure way.

I hope this helps.

The problem with plink is this matter is

If i instruct it to execute the command remotely then it says "Authentication Failed" becoz as I provide the password for Unix ServerA it auto switches to Unix ServerB which is where rather than prompting for the password for the second time for unix ServerB it reads the command
Code:
mkdir

and passes the command as an input to the password.

I hope you now understand what the problem is.

Now, can you please help me get the mkdir command somehow executed on unix ServerB from my windows ?

If "plink" can't be brought to do what you want consider alternatives. Use "ssh" or whatever else i already told you.

have a look at the startup files for your unix server too: it isn't usualy to immediately ask for a password for another machine. If you have an automatic connection to a remote system in some profile you should remove it, but this has nothing to do with the script at hand, just with the configuration of the remote system.

Anyway, this is all guessing wildly in the dark until you show any relevant information. Trace the process of running he script thoroughly *on both systems* and present *any* outcome here (unfiltered, instead of telling us about what you think the output might have been meaning).

This might get solved the problem, anything else is ultimately idle chit-chat.

I hope this helps.

plink can take the password as a parameter, you don't have to jam it into stdin.

You should be checking the commands you run for success or failure, anyway.

The problem with this is, I am using Soft Token and the random password gets generated every 1 minute and the same password cannot be used twice.

It uses the first password for login to unix server A, and then expect a new random generated password for unix server B which I am not sure how to pass using plink along with the mkdir command.

the ssh option with plink does not do anything different.

plink -ssh user1@244.60.212.17 -pw 724494

It logs me in to unix ServerA and then to unix ServerB where is prompts for the password. Then I am into the unix shell from my windows shell as seen in the snap below.

In unix Server A home directory I see this mechanism to make it auto-switch to unix ServerB.

more .profile

Code:
echo "Connecting to: Server2"
exec /usr/local/bin/dev13
                exit
