[gentoo-user] SCP bash script

Hi guys,

I have a problem with scp bash script. I was trying to automate scp command
to copy files in and out, and I was trying to avoid key in the password
myself.

So I attempt to use the "here string" feature of bash, it didn't work with
scp.

And those server I am working with, they don't have expect package
installed. :-(

ps. I am not supposed to change the configuration of the servers( includes
setup openssh keys, or install expect)

You guys have any idea that can help this case?

Thanks & Regards,
kit393

Typically you would copy local:~/.ssh/id_dsa.pub (or non dsa
equivalent) into remote:~/.ssh/authorized_keys - since that's only
user level, no need for root access. Its changing the configuration of
the user on the remote machine, but since that user is you, its
usually ok.

You then use -i with scp.

Right, I am just not sure that's the only way. Since I just want to copy
one file in and one file out on many servers, this solution will double the
work. It's just for servers auditing, you know.

But thanks a lot anyway. Appreciate you help. :-)

Well, expect is generally used client-side and doesn't require a
server-side counterpart, assuming you're pulling files to, or pushing
from, a machine you do have actual control of.  SSH keys are the usual
means, since they don't involve writing a password somewhere in plain
text, but lacking those, expect on your own machine would do the
trick.
