[ACCEPTED]-Using expect to pass a password to ssh-expect

Accepted answer
Score: 79

I always used the "proper" solution, but 2 I used expect in other situations.

Here I found 1 following suggestion:

spawn  sftp  -b cmdFile user@yourserver.com
expect "password:"
send "shhh!\n";

Would it not be easier to use public key 5 authentication and use a key with no passphrase?

As 4 the user on the source machine do this to 3 make an RSA key

ssh-keygen -t rsa

Now copy ~/.ssh/id_rsa.pub 2 to the target machine and append it to the 1 authorized_keys file of the target user

Your quickest way forward (unless you want 11 to become a Tcl expert, which would be... unusual... in 10 2009) is probably to use autoexpect. Here's the man 9 page:


In short, fire up autoexpect, run your ssh session, finish 8 up what you need to do, stop autoexpecting 7 and then beat your keyboard over the resulting 6 mess until it works :) I'm assuming you 5 don't need anything more than a quick hack 4 to get your keys sorted out and then, well 3 it sounds like you know the score already 2 with that.

And there's this question which already contains 1 an example close to what you seek.

Cygwin has autoexpect just not in the bin 6 package. run setup.exe and search for expect 5 and check the source checkbox. you will 4 see the resulting tree in /usr/src and in 3 there there is a expect/expect/examples 2 directory. in there lives a copy of the 1 autoexpect script.

Key solution will not work... because the 5 keys have to be readable only by the person 4 running ssh. On xp you cannot create key 3 structure with the correct permissions. So 2 ssh will not read them. This may have changed, but 1 last i checked it still not not work.
