ssh redirection

[ddanj]

So i'm trying to automate input for SSH. I know I could do it with expect, or by havint authrized_key on all the machines, but I want to do it in another way if possible.

I'm trying to basicly do this:

ssh root\@$machine > file

but i'm getting this error:

'Pseudo-terminal will not be because stdin is not a terminal'

I think this means, that ssh only accepts input from a 'terminal'

is there any way around this?

thank you

wheres the edit button?

'Pseudo-terminal will not be because stdin is not a terminal'
should be

'Pseudo-terminal will not be <b>allocated</b> because stdin is not a terminal'

It's a security feature. If you're calling it from your own scripts then you could be storing key passwords in clear text which is undesireable. If you want totally automated operation, I'd use a host key without a password. ssh will let you do this as it can check the security of the file containing the key (I think;-).

If you really want the interactive ssh, then something that creates a pseudo terminal is necessary and expect is your best bet.
