SFTP is Secure File Transfer Protocol. It is similar to ssh, but its primary purpose is to enable file transfers between a local machine and a remote machine, whereas the ssh (Secure Shell) protocol is for opening up a general command shell on a remote machine where you have an account. Like SSH itself, SFTP is a client-server protocol. SFTP clients are included in quality SSH clients and complete enterprise grade SSH implementations provide both SFTP client and server functionality. Some SSH clients, such as Tectia SSH, also provide graphical file manager views into remote filesystems. SSH File Browser and Explorer Our web SFTP client makes it easy to copy files and folders both from local to remote and from remote to local. Under the hood it uses the SSH File Transfer Protocol also known as SFTP Access your sftp from your browser. A secure flexible SSH client with SFTP file transfer and rock-solid emulations that is suitable for developers, administrators, or deployment across the enterprise. It includes the industry standard SSH protocols to secure terminal session data across insecure environments such as the internet. SFTP (SSH File Transfer Protocol) is a network protocol that provides file access, file transfer, and file management over any reliable data stream. It was designed by the Internet Engineering Task Force (IETF) as an extension of the Secure Shell protocol (SSH) version 2.0 to.
Many Unix environments have the command-line SSH and SFTP client software tools installed. This page is intended as a guide to just the basics of using these command-line tools. They have many more features than what is described here -- but these instructions should get you started.
Where would I use these?
CS account
If you have a CS account, you have access to at least three machines you can log into:
shell.cs.fsu.edu
program.cs.fsu.edu
linprog.cs.fsu.edu
These machines all mount your home directory, so there's no need to SFTP between them.
You might also have an account on websrv2.cs.fsu.edu. This would not mount your normal CS account directory, so you might need to file transfer between this machine and others
Mac OS X home computer / laptop
If you have a Macintosh laptop or home computer running OS X, you cannot use the Windows SSH client unless you're running Windows emulation or have booted into Windows
In this case, you can use the terminal application (which takes you into a Unix prompt on your Mac) and run the command line SSH and SFTP programs from there
This is useful for logging into your CS account remotely, as well as doing file transfers between your Mac and your CS account
To open the terminal application on a Mac:
Go to the spotlight icon in the upper right of your desktop
In the search box, type 'terminal'
A menu choice for the terminal application should appear. Select this
Using command-line SSH
Login format:In this format, username refers to your user name on the remote account you are logging into, and
Ssh And Sftp Client Software
host_name refers to the name of the machine (usually along with doman) that you are logging into
If you leave out the username, the command will assume that you are logging into another machine with the same username as the machine you're currently on.
Examples
Suppose I'm on a Mac, logged in with user account 'john'. This command would log me into shell.cs.fsu.edu as username 'smith':This command would log me into shell.cs.fsu.edu, attempting username 'john' (probably will fail, since john is probably not your CS account username!):
You can also log into the machines program or linprog:
Using Command-Line SFTP
SFTP is Secure File Transfer Protocol. It is similar to ssh, but its primary purpose is to enable file transfers between a local machine and a remote machine, whereas the ssh (Secure Shell) protocol is for opening up a general command shell on a remote machine where you have an account.
The login format for command line sftp is exactly the same as with the ssh command, but with the 'sftp' command:Using the same basis of the prior example, this command would log me into shell.cs.fsu.edu with the sftp (file transfer) program as username 'smith':
Local vs. Remote machines
Before you transfer files, make sure you know the difference between the local and remote machines:
The local machine is the one you started from -- i.e. the machine you were on when you typed the 'sftp' command. This might be your actual physical computer, like a MacBook, if you're using the terminal application. This might also be a machine you are logged into through ssh
The remote machine is the one you just logged into via the sftp command
Examples
Suppose I'm on my MacBook, with username john. I open the terminal application and sftp into linprog.cs.fsu.edu with username smith:In this case, the local machine is my MacBook, and the remote machine is linprog
Suppose I've already logged into user account smith on shell.cs.fsu.edu through an ssh command (or any SSH client). From my CS account, I type this command:Now I have logged into the machine websrv2, with the same user account smith. In this case, the local machine is shell.cs.fsu.edu, and the remote machine is websrv2.cs.fsu.edu.
Basic file transfer commands
There are more commands available than this, but the primary commands you will need are:
put -- copy a file from the local machine to the remote machine
get -- copy a file from the remote machine to the local machine
ls -- get a directory listing on the remote machine
cd -- change your current working directory on the remote machine
lls -- get a directory listing on the local machine
lcd -- change your current working directory on the local machine
Note here that the ls (list files) and cd (change directory) commands work exactly as you are used to them from a regular unix shell. Except when you use them as-is, you are requesting a listing or a change directory operation on the remote machine -- i.e. the machine you just sftp-ed into.
If you want to get a directory listing or change directories on the local machine, use the lls (local list files) and lcd (local change directory) commands instead.
I'm not going to describe these commands (listing and change directories) any further, as readers of this file should already be familiar with these unix commands
put and get commands
Once you have used the listing and navigation commands to put yourself in the correct directories, use get to retrieve files from the remote machine to the local account, and use put to send files from your local account to the remote account. The formats of these commands are simple, and you may use unix wildcards.
Queen guitar pro. Format:Note that the second parameter of each command is optional -- and it will serve to specify a different name or destination directory for the transferred file. Helio p70 phones under 8000. Most of the time, it's easiest to simply use put and get with a single parameter, and the destination will default to the current remote or local directory, respectively.
Examples
This command will copy the file mycode.cpp from the remote machine to the local one:
This command will copy the file mypaper.doc from the local machine to the remote one:
This command will copy the file assign1.cpp from the remote machine, and save it as smith1.cpp on the local machine:
This command will copy all files ending in .cpp in the current directory on the local machine to the remote machine:
Other SFTP commands
To see a full list of SFTP commands and their formats, you can type help
Ssh And Sftp Client For Windows
when you are logged in via sftp, and it will give you a list of available commands.
To exit the sftp login, you can use either the quit or the exitNpm cheat sheet. command.
