Dreamweaver

Who needs to do this?

Anyone who edits their website using Dreamweaver and hosts their website on the Public Linux / Volweb server.

Why does this need to be done?

Two-factor authentication is in place across most university technologies and is now required to securely access the UT Public Linux environment. Due to this change, uploads previously performed through Dreamweaver’s native file sync process will no longer work. While you may continue to manage and update your website files using Dreamweaver, any updated files will require connecting through a Secure File Transfer Protocol (SFTP) client (preferred) or Secure Shell Host (SSH).

Items to prepare beforehand

Begin the upload process using the following steps:

1. From your desktop, locate your website folder containing your web files.
   • Not sure of the location of your local website files? 
     1. Launch Dreamweaver.
     2. Navigate to Site > Manage Site.
     3. Select the name of the site within the dialog box.
     4. Select the pencil icon to reveal file location settings. The Local Site Folder will display the location of your website files, i.e., User/computer name/Documents/Folder name/
2. Locate and open your SFTP Client, such as Cyberduck or FileZilla.
   • Log in to your Public Linux / Volweb account
   • Locate your public_html directory
     
     Not sure how to configure an SFTP client?
     View detailed instructions on configuring an SSH/SFTP client.
3. In your public_html directory on the server, locate the remote files you wish to update. On your desktop, in your website folder, locate the local files you plan to upload.
   Your local and remote web directories should match except for any local changes you made within Dreamweaver.
4. Since the process overwrites files on the server, before uploading new files, save a backup copy of your remote files by clicking and dragging the public_html directory from the SSH/SFTP client to your desktop or another local backup location.
5. Upload the new files by:
   1. Selecting the new/updated web files in your local website folder on your desktop
   2. Copying or dragging the files into the matching folder in your public_html directory
