In Take Control ofīBEdit (TidBITS, $10.00 USD) long-time BBEdit user Glenn Fleishman has taken up the challenge of explaining how to accomplish real-world tasks more quickly and efficiently in BBEdit 10.Ĭreated in collaboration with Bare Bones Software, Take Control of BBEdit describes handling core text-processing features that are essential for all users, working with HTML from the level of the individual tag all the way to a dynamic Web site, and managing multi-resource projects. For Mac users who blog, write HTML, code, use grep, or otherwise manipulate text, BBEdit's sophisticated tools can save vast amounts of time and effort. Keyboard interactive is mostly used for one-time passwords and similar.Ithaca, NY-BBEdit, from Bare Bones Software, is the preeminent text editor on the Macintosh, with a nearly 20-year history and an abundance of powerful features.Public key requires acess to the private part of the public key you use for authentication (typically, you setup the key pair on the client and just update the server configuration with your public key).Password requires a username and password combination. ![]() The Wiki article on SSH has plenty of juicy details but, to summarise, there are 4 supported authentication mechanism: The key pair you use for authenticating, however, can be optional (or disallowed) depending on what authentication method you've decided to allow or require on the server. The server key pair is mandatory but it is typically generated during the installation of the server: all you have to do is validate the server public key fingerprint (a simple hash) and, as long as the key is unchanged, your client will silently connect. In SSH, you have two sets of key pairs: one for the server and one for the users. By definition, only the key-based authentication requires that the client stores and uses a key pair of its own. Password-based authentication and key-based authentication are the two most common methods (some servers are configured to require both). about how the server will make sure that it is talking to the right client. This means that you don't have to "create a key" when you configure your SSH server to also be used as SFTP: the server already has a key.Ī client may have a public/private key pair if it wishes to be authenticated based on that key this is all about client authentication, i.e. ![]() Linux) create a SSH key pair when first installed, and will use it thereafter. That key is used for the tunnel part, so a server will use the same key pair for all applicative protocols. The server MUST have a public/private key pair. This means that any authentication concept applies equally to SSH (the "remote shell" part) and SFTP. From the SSH point of view, which application is used is irrelevant. Another, distinct application is the file transfer protocol known as SFTP. One such application is the "remote shell" which is used to obtain an open "terminal" on a server, in which terminal applications can be run. SSH is a generic tunnel mechanism, in which some "application data" is transferred. ![]() ![]() There may be a public/private key pair on the client, but the server may elect to authenticate clients with passwords instead, Short answer: there is necessarily a public/private key pair on the server. Initially, I though that they were the same public/private key pair. I did not understand that there are two sets of public/private keys in use, one that is created by the server and one that could possibly be created by the client. Originally, I thought that I needed to create these pairs for each individual that wanted to connect to the server and manually copy the public key file to the clients machine. How is SFTP (which I have read is based on SSH) able to function without a public and private key pair (or is it defaulting to an insecure mode like FTP in the situation?) I thought that the public and private keys were a fundamental element of how SSH worked. Gettin gin a little deeper, the docs for WinSCP never tell me to set up a public or private key pair on my client and server. Everything that I have read so far indicates that I need to use an SFTP client (like WinSCP) to connect to my server and transfer files. I am learning about SSH and how to use it to secure file transfers and commands between a windows machine and a Linux server.
