Securing the connection using SSL/TLS is available in two different ways, FTPES and FTPS. With FTP (File Transfer Protocol) commands and data transfer take place in plain text.
It is closed as soon as all the data has been sent. The data connection persists only for transporting the required data. In passive mode, the client opens also the data connection. In active mode, the data connection is opened by the server back to a listening client. This is referred to as the FTP data connection (as opposed to the previously mentioned command connection). If the FTP command requires the server to move a large piece of data (like a file), a second TCP connection is required to do this. Most FTP clients support a verbose mode which will allow the user to see these codes as commands progress. See the RFC for a complete guide to reply codes. Generally codes in the 200s are success and 500s are failures.

The servers replies consist of a 3 digit code (in ASCII) followed by some explanatory text. All commands are terminated by a carriage return-linefeed sequence (CRLF) (ASCII 10,13 or Ctrl-J, Ctrl-M). The FTP commands from the client to the server consist of short sets of ASCII characters, followed by optional command parameters.įor example, the FTP command to display the current working directory is PWD (Print Working Directory). This connection is referred to as the FTP command connection. This connection is then used to convey commands from the client to the server, and the server replies back to the client. This TCP connection persists for as long as the client maintains a session with the server, (usually determined by a human user). The server does a passive open (a socket is listen) when it begins operation thereafter clients can connect with the server via active opens.

But I do feel bad about letting a PC with a 150 watt power run all of the time.When an FTP client contacts a server, a TCP connection is established between the two machines. I don't feel bad letting a computer that draws under 10 watts just run. It was my rtl_tcp server for a while.Īll of these systems ran 24x7 for months and years.

When the phone goes off at 2 AM, all I have to do is type in a few passwords, and I've got a remote desktop running before I've even woken up. Highly secured so I can SSH into and remotely administer systems at work. I installed Remmina and Firefox/Iceweasel into it, and almost nothing else. Also is a NAS and FTP server and web server and some other stuff. Also is a DLNA server for the Blu-ray player and tablets and phones and Chromecast. Plays music and streams into the entertainment center. Also runs a cron job every few minutes to check the web server and audio stream server at work, and emails me if there is a problem. The best thing? The base model is only $20 $5!.ĭo you know a related subreddit? We'd love to know.įirst Pi-2 plays music into the Aux-In of my alarm clock.
