#!/usr/bin/expect
set timeout 10
log_user 0
spawn scp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $REMOTE_CREDENTIAL_USERNAME@$host_name :$

expect "*?assword"

Simple but useful

1)  Share your files and folders residing on your Linux machine with anyone across the web.

Here is the simple way to share files across network on linux , without the need of SMB or NFS .

Open a bash terminal and create an alias as follows:

Next navigate to the directory which you want to share with someone and run  $ python -c "import SimpleHTTPServer;SimpleHTTPServer.test()" command

Your Linux machine will now start serving the whole directory tree on the port number 8000.

And anybody can access all your files within that directory at the following web address – http://:8000/.

Tip:

If you have firewall enabled , you need to open port 8000.
