Shell Programming and Scripting

Hi All, I am having an issue with my script which I am using to get files from a remote server.

In my script I am going to server:- REMOTESERVER and directory:- /Interface/Upload, and then getting files from there to my local server directory:- /ftp/jail_nextview_LMS/home/nextview_LMS/outbox.

Could you please look at my script file once and the error log and help me to understand why this error is coming, it will be a great help, thank you very much.

It's telling you that it couldn't connect to REMOTESERVER, because the connection timed out. Unless you got the hostname wrong or something, not something you can correct on your end.

Why are you using a brute-forcing tool to inject plaintext passwords into sftp when you can save yourself a lot of complication and trouble and use keys?
