How do I use FileZilla to transfer data?

File transfer from Mac clients connecting to MSI Unix servers can be done with many different clients. MSI recommends FileZilla as a reliable utility.

To Set Up FileZilla:

  1. Start the FileZilla application to get this screen:


  2. Enter s (or s into the Host box, your username into the Username box, your password into the Password box, and 22 into the Port box. Click on Quickconnect.


  3. The first time you connect you may get a window asking you to confirm the identity of the server. Click on the "Always trust this host" checkbox and click on OK to continue.


  4. You are now connected to the server, you can copy files to and from the remote machine by dragging them them back and forth.


To Shutdown FileZilla:

  1. While connected click on the "Disconnect" button in the FileZilla window.


To fix "Authentication Failed. Critical error: Could not connect to server" error when transferring files:

Filezilla on Macs cache passwords, which are not automatically updated.  This can cause an issue when a user changes their UMNid password and updates it within Filezilla when trying to connect to MSI login servers.  A connection with the new password will be established, but when the user attempt to move files, Filezilla will attempt to use the cached password, which causes an "Authentication failed.  Critical error: Could not connect to server" error.  

The fix is:
  • Go to Filezilla preferences -> Select Interface in the left pane
  • check the box Do Not Save Passwords. 

To fix "Filezilla can't be opened because it is from an unidentified developer" error:

Newer Macs allow only certain approved programs to be installed by default. Filezilla is not recognized as an approved program, so if you receive an error such as 'Filezilla can't be opened because it is from an unidentified developer', you'll need to follow the below steps:

  • Open 'System Preferences > Security & Privary > General
  • Change 'Allow applications downloaded from' to 'Anywhere'
