![]() Once you’re connected, you can navigate the FTP server with the dir and cd commands. If you don’t have one, you can enter “Anonymous” followed by a blank password to see if the FTP server allows anonymous access. Enter the username and password to connect to the site. For example, to connect to Microsoft’s FTP server, you’d type: open To connect to a server, type open followed by the address of the FTP server. The prompt will change to an ftp> prompt. On Windows 7, search the Start menu for “Command Prompt”. On Windows 10 or 8, right-click the Start button or press Windows+X on your keyboard and select “Command Prompt”. To do this, open a Command Prompt window. This command is comes built into Windows. You can also do this with the ftp command in a Command Prompt window. How to Access FTP Servers in the Command Prompt Download files and upload files by copying and pasting them to and from this folder. When you’re done, the FTP site will appear under “Network locations” in the This PC or Computer pane. Enter whatever name you like–the FTP site will appear with this name so you can easily remember which is which. You’ll now be asked to enter a name for the network location. The first time you connect to the FTP server, you’ll be prompted to enter your password. If you do have a username and password, enter your username here. This gives you limited access to the server–you can generally download publicly available files but not upload files, for example. If you don’t have a username and password, you can often check the “Log on anonymously” box and sign into the server without a username and password. In the “Specify the location of your website” dialog, enter the address of the ftp server in the form .įor example, Microsoft’s FTP server is, so we’d enter here if we wanted to connect to that particular server. Go through the wizard that appears and select “Choose a custom network location”. Right-click in the right pane and select “Add a network location”. To connect to an FTP server, open a File Explorer or Windows Explorer window, click the “This PC” or “Computer”. The Windows file manager–known as File Explorer on Windows 10 and 8, and Windows Explorer on Windows 7–allows you to connect to FTP servers. Any user can log in using the username "anonymous" and typically use their email address as the password.Īnonymous users will typically log in by using a user name of ftp or anonymous, and most users will use their e-mail address as a password.How to Access FTP Servers in Windows’ File Explorer I was not prompted for a username and password but you can see that IE provided them for me.Īnonymous FTP is an FTP service that does not require a unique username and password to log in. Here's a packet capture of me opening the same FTP site in IE. If you run a tcpdump or packet capture on your client machine you should see that the username being passed to the FTP server is the word "anonymous" or "ftp" with a password like the one I described above. Web browsers and FTP clients will pass the username "anonymous" to an FTP server with a password like or something to similar effect. I just want to understand what's going on.Īnonymous doesn't mean "no user" or "null user", it means "anonymous user", as in the username passed to the FTP server is the word "anonymous" (or sometimes the word "ftp"). No, I'm not asking for advice on how to do black-hat hacking. Or maybe this is just an inherent weakness in FTP. It seems either they didn't secure their server properly, or they did, and I just walked into a honeypot. If you do not have explicitĢ30- permission to access this system, please disconnect immediately!Ģ30 -Ģ27 Entering Passive Mode. But I kind of got the feeling that I wasn't supposed to be able to do that, because my session looked something like this: bash-3.2$ ftp -a Ĭonnected to .net.Ģ30-Ģ30- WARNING: This is a restricted access system. Not too strange I mean, some FTP servers have an authenticated mode and an anonymous mode. ![]() But when I did an anonymous login, it didn't prompt for any authentication information. When I logged in using the regular mode (non-anonymous), it prompted me for a username and password. Basically what happened was, I logged onto a non-anonymous FTP server anonymously. I think an understanding of what is going on might shed light on the nature of the FTP protocol and securing FTP servers.
