hey can you tell us what is the contents of your login.txt file. because your script is not able to take the 192.168.12.1 from your login.txt file.

The problem is because your sh script is not finding your expect script: sshlogin.exp.

Try the following:

CONNECT=<FullPathTo>/sshlogin.exp
# Or
export PATH=${PATH}:<FullPathTo sshlogin.exp>

I hope it helps.

What is your expect script doing? Can you post it here?

If you are in the box that has the: "autoexpect" command, try to use it to generate a script that suit your needs.

Here is a link to an online autoexpect man pages: Unix man pages: autoexpect (1)

Regards.

I guess you should try to SSH login without password.

Having a password anywhere in a file is a security hole.

I changed all my routines to use ssh public key authentication, and this is an excelent link: OpenSSH Public Key Authentication
