SFTP

SFTP

SourceForge.net provides support for managing project web, developer web content, and uploading file releases using SFTP through our File management service.

SFTP (Secure file transfer protocol) is part of the SSH protocol suite. SFTP is not the same as FTP; SFTP is a modern, encrypted protocol and FTP is an old, unencrypted protocol. We do not support FTP.

SFTP is served via Port 22 if you are using a GUI client.

The first time you connect to web.sourceforge.net or frs.sourceforge.net you will be prompted to check the SSH Key Fingerprints, to check these, please see the following SSH Host Key Fingerprints list.

Authentication

Authenticating via SFTP requires the use of a "combined" username for the project web space. The combined username is composed of your SourceForge.net account username and the project UNIX name for which you want to upload or download files. A comma (",") is used as a delimiter between these two components.

Example:

SourceForge.net username: jsmith
User jsmith has a project with the UNIX name: fooproject
Combined username: jsmith,fooproject
Note: The Developer web space and the FRS system only require the use of your SourceForge.net account name.

The password for both cases is always the password associated with your SourceForge.net user account.

Clients

SFTP is served via Port 22

SFTP clients include:

• sftp, a command-line client included in OpenSSH, available on Mac OS X, Linux, and BSD natively; and on MS Windows through Cygwin.
• psftp, a command-line client included in PuTTY, available for MS Windows.
• WinSCP, a graphical client available for MS Windows.
• FileZilla, a graphical client available for MS Windows, Mac OS X, and Linux.

Examples are provided for sftp:

For managing file releases

FRS Hostname: frs.sourceforge.net
Path: /home/frs/project/P/PR/PROJECT_UNIX_NAME/ - Substitute your project UNIX name data for /P/PR/PROJECT_UNIX_NAME
Username: Combine your SourceForge.net Username with your SourceForge.net project UNIX name using a comma ( "," ) See Example
Password: Your SourceForge.net Password
An example session might look like (where Username="jsmith", Project UNIX name="fooproject",Release dir is "Rel_1"):

[jsmith@linux ~]$ sftp jsmith,fooproject@frs.sourceforge.net

Batch mode

To use sftp in batch mode, you need 3 things:

• Use key-based authentication, since password entry can't safely be automated.
• Have the batch file in the form of "put filename1 \n put filename 2 \n etc..."
• Use username,groupname so that access to the files afterwards is possible (See Example).
