We don't necessarily encrypt an entire file using RSA encryption. Given a public key, it should be - and in fact is with today's computers - impossible to derive the private key. The public can be used to encrypt data while the private key can be used to decrypt data. Or, more simply, matching a public/private key is like recognizing a face or a voice: it is a means of establishing identity. The box can't be opened unless both keys are present. It's a bit like having two keys to a safety deposit box, both of which are needed to open the box. If our private key matches the public key we gave to others, then we have proved our identity. We keep the private key, we give the public key to others. This is accomplished by means of creating a mathematically unique public/private key pair. SSH is designed as a means of proving our identity and encrypting data in the most secure and reliable manner possible. Furthermore, over the web, we have to be able to transmit data in encrypted form so others can't see it. None of these things work very well over the web, particularly when we are trying to prove our identity to an abstract entity such as a web site. Identity can also be established by a signature, or by asking a question that only certain people can answer can answer. If we talk on the phone, I can know who you are by recognizing your voice. If we are in the same room, I know who you are by looking at your face. SSH is a means of establishing identity on the web. Pinging a machine is meant to be a way of asking the question: "Are you Pinged, then that often means that the machine does not have ports 80 If the ping succeeds but you can't browse or SSH to the machine you (Or you might have the wrong address for the machine.) Work, then either the machine isn't running, or else the network isn't However, as a general rule, if ping doesn't Responds to pings, and hence a machine won't respond even though it is Sometimes an admin for a machine will close down the service that Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Reply from 192.168.0.101: Destination host unreachable. When an attempt to ping a machine fails, your session might look like On Linux, however, the process of ping a machine will continue On Windows, a session with PING ends by default after four iterations.
Works, the session should look something like this: C:\Users\Charlie>ping 192.168.0.123 Pinging 192.168.0.123 with 32 bytes of data: Network is to go to the command prompt and try to ping it. One way to test if a machine is available on the The machine with which you want to communicate is running and signed Usually best, however, to start at the beginning and determine whether Receiving an error when attempting to use one of these protocols. Sometimes you might try to use SSH, SFTP or HTTP to communicate with a

Linux boxes come with SSH already installed or easily Line sessions and for the Secure File Transfer Protocol (SFTP).Īs a general rule SSH is part of the Unix world and not part of the Protocol that supports very secure communication both for remote command The ability to communicate securely across a network is a fundamentalīuilding block for those seeking expertise in Cloud computing. So you should focus your attention on those sections when reading this document. On Lubuntu we use commands that begin with the letters ssh such as ssh-add and ssh-keygen. Since we use Lubuntu it is no longer necessary for my students to learn about Putty. Learning about Networks, SSH, SFTP and Putty.
