Dealing with Host Keys in Plink through AutoIT

8 posts in this topic

#1 ·  Posted (edited)

I am very new to AutoIT scripting (and programming in general), so be kind. :rolleyes: Can anyone tell me why this line of code won't work?

RunWait("echo y | plink -ssh -pw root root@" & $IPaddress & " exit")

I'm trying to deal with that annoying message: "The server's host key is not cached in the registry. You have no guarantee that the server is the computer you think it is. The server's rsa2 key fingerprint is: ssh-rsa 1040. If you trust this host, enter "y" to add the key to PuTTY's cache and carry on connecting. If you want to carry on connecting just once, without adding the key to the cache, enter "n". If you do not trust this host, press Return to abandon the connection. Store key in cache? (y/n)"

If I type in the part in parenthesis directly into a command window, it will work as written. But when I run it in the script, it will get to the y/n prompt and stop, as though it doesn't recognize the "echo y |".

And certainly, if someone has a more appropriate way to get this done, I'm certainly open to it.

Thoughts, ideas, recommendations?

Thanks in advance!

:ILA3:

Try with this:

$sCommand = "echo y | plink -ssh -pw root root@" & $IPaddress & " exit"
RunWait(@ComSpec & " /C " & $sCommand)

Hooray! Thanks, Nessie... it works beautifully.

I get what you did there with defining the command string as a variable, but can you explain to me what exactly the @ComSpec macro does and when I would know to use it?

Thanks again for your help!

The help file would be the best place to look for this information, it's loaded with this kind of stuff.

@ComSpec - Value of %comspec%, the SPECified secondary COMmand interpreter primarly for command line uses, e.g. Run(@ComSpec & " /k help | more")


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

@Brewman... thanks, and that is the first place I looked when I got the reply, but as a newbie to programming, "the SPECified secondary COMmand interpreter" didn't really make a lot of sense to me.

This "%comspec%" should have told you something. It's an environment variable that points to the command interpreter. Usually any time you see something refereneced with "%" before and after it, it's an environment variable, and if you want to know what that value equals, you can put it in a MsgBox to have it display for you. "MsgBox(0, "", EnvGet("comspec"))" will display a message box with the value assigned to %comspec%.

Thanks for helping me learn a little more, BrewMan. Someday, I might actually know what I'm doing! :-)

As my mother says, it's a sad day when you don't learn something new. :D
