Ping sftp server

File Transfer Protocol (FTP) was a widely used protocol to transfer files or data remotely in an unencrypted format which is not a secure way to communicate.

As we all know that File Transfer Protocol is not at all secure because all transmissions happen in clear text and the data can be readable by anyone during sniffing the packets on the network.

So, basically, FTP can be used in limited cases or on the networks that you trust.

Over the period of time, SCP (Secure Copy) and SSH (Secure Shell) addresses this security ambiguity and added an encrypted secure layer while transferring data between remote computers.
