• Log in as root user on your Mac
• Copy the firmware file to folder/private/tftpboot
  • /private/tftpboot is the default target folder for the TFTP server. If necessary, the target folder can be moved. Please see instructions below to relocate the target folder.

Changing the default TFTP folder:

• Open a Finder window
• Navigate to /System/Library/LaunchDaemons
• Using a plain text editor, modify tftp.plist
• Look for the following lines

<key>ProgramArguments</key>

<array>

<string>/usr/libexec/tftpd</string>

<string>-i</string>

<string>/private/tftpboot</string>

</array>

• Change the third <string> line from /private/tftpboot to another folder. This will move the TFTP server's target folder.
• For example, change the path to secure location like /var/tftpfiles
• Then make a new folder matching the change

<key>ProgramArguments</key>

<array>

<string>/usr/libexec/tftpd</string>

<string>-i</string>

<string>/var/tftpfiles</string>

</array>

• When done, save tftp.plist
• Now the TFTP server will look in /var/tftp_files folder for all TFTP file transfers
• You must either restart your Mac or restart the TFTP server to have the changes take effect.

The macOS and OSX operating systems come with built in FTP, TFTP, SFTP, and HTTP servers. Here is how to enable them and use them.

FTP Server

To start an FTP server use this terminal command:

Users will need to authenticate to the macOS system using standard logins that are already on the macOS. When someone logs in, they will arrive in /Users/<username>/.

To stop the FTP server, run the following:

TFTP Server

The directory that serves files is /private/tftpboot.

To stop the TFTP server, either reboot or use this command:

SFTP Server

Ssh tunnel for ftp os x. This one is different. Go to system preferences then Sharing. Check the box to enabe Remote Login. Once this is done, other people will be able to ssh and sftp to your macOS system.

HTTP Server

Apache comes bundled with macOS. To start it, run this command.

By default the files will be served from /Library/WebServer/Documents.

To disable the server, either reboot or do this command:

Checking Status

To check to see what’s running, run the command:

This will show you which ports are open on your macOS. For example if you have Apache running, you will see the following:

• HTTP = TCP 80
• FTP = TCP 21
• SSH = TCP 22
• SFTP = TCP 22
• TFTP = UDP 69

Note that TFTP is on UDP and won’t say listen. Just run netstat -an grep 69 to find if it’s running.
