Shell Programming and Scripting

I need to automate a file transfer thru SFTP. But I cannot do a passwordless key with ssh-keygen between the servers. Is there any other way like we do something like below in FTP???

Code:

ftp -n hostIP << EOF
user userid password
get filename
EOF

If you have the expect tool you can use that to create an automatic SFTP login/send script, for example.

What OS do you have?

Solaris

Have patience and search in the forum first.

"interactive password authentication" means "password typed by a human being in realtime authentication". That's the only way it's supposed to take a password, and they did everything they feasibly could to prevent you from brute-forcing it any other way.

There's a reason you have to install third-party hacking utilities to even try -- it's a bad idea to keep recoverably stored passwords around, and completely avoidable.
