Why Standard FTP?
Why would you want to turn on a standard, non-secure FTP server on your ATV?? Well the answer for me was simple . . . SPEED!!!
Here's my setup as an example: iMac -> wireless 802.11n -> Airport Extreme -> Ethernet cable -> ATV
SFTP - Avg xfer speed = 2Mb/s
FTP - Avg xfer speed = 7Mb/s!!!!!
That alone was a good enough reason for me! If you're worried about security then you should stick with the SFTP server which is usually installed when using the Patchstick.
There is already an FTP server on the AppleTV just waiting to be activated. It's relatively simple to do so. Cut and paste the seperate code blocks into a terminal window:
Give super-user privileges:
ftpd directory for ATV 3 You have to substitue the path to ftpd in ATV 3 from /usr/libexec/ftpd to:
Write the FTP configuration file:
cat <<EOT > /System/Library/LaunchDaemons/ftp.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.apple.ftpd</string> <key>Program</key> <string>/usr/libexec/ftpd</string> <key>ProgramArguments</key> <array> <string>ftpd</string> <string>-l</string> </array> <key>Sockets</key> <dict> <key>Listeners</key> <dict> <key>Bonjour</key> <true/> <key>SockServiceName</key> <string>ftp</string> </dict> </dict> <key>inetdCompatibility</key> <dict> <key>Wait</key> <false/> </dict> </dict> </plist> EOT
Reload that configuration file after changing it:
launchctl load /System/Library/LaunchDaemons/ftp.plist
Simple as that. It should start working right away.
ATV Take 2 FTP
To enable FTP server in ATV Take 2 you will also need to copy the following file which is missing in Take 2: ftpd.
Copy it from /usr/libexec/ftpd (tiger) to the same location on the ATV. Alternately, you can find an updated ftpd in MacOSXUpdCombo10.4.11Intel.dmg Don't forget to chmod +x ftpd
If you have a 1.0 recovery partition do the following (Don't have a 1.1 image to test):A)
sudo mount -uw / sudo touch /.readwrite cd ~ sudo dd if=/dev/disk0s2 of=recovery.dmg bs=1m hdiutil mount recovery.dmg hdiutil mount /Volumes/Recovery/OS.dmg sudo cp -p /Volumes/OSBoot\ 1/usr/libexec/ftpd /usr/libexec/ftpd sudo chmod +x /usr/libexec/ftpd sudo chown root:wheel /usr/libexec/ftpd
For ATV 2.1 you must also add "frontrow allow" to the /etc/ftpusers file so that you can login with the frontrow user.
From your local machine, copy the /etc/ftpusers file to your local machine
scp -1 email@example.com:/etc/ftpusers $HOME/Desktop
The file will be copied to your Desktop. Open it with TextEdit (or your favorite ASCII editor, since I'm a geek I prefer 'vi'), and add the "frontrow allow" line to the end of the file.
After the edit your ftpusers file should look like this:
# list of users disallowed any ftp access. # read by ftpd(8). Administrator administrator root uucp daemon unknown www frontrow allow
Ensure that you DO NOT add the ".txt" extention to the file, it should only be called "ftpusers".
All that remains is to copy it back to your ATV, ssh to your ATV, change the ownership and copy it back to the correct location.
From your local machine:
scp -1 $HOME/Desktop/ftpusers firstname.lastname@example.org:~ ssh -1 email@example.com <enter 'frontrow' as the password when prompted> sudo chown root:wheel ftpusers sudo mv ftpusers /etc/ftpusers
B) Then perform the steps listed above for the 1.x installation
Anonymous Write Access
To allow anonymous access (with write support) several steps need to be taken. Don't do this if your Apple TV is directly connected to the internet for what ever reason!
There are several steps here which may not be required - so this may need a little cleaning up.
Get into the correct state
Create the directory where the anonymous user can dump files
mkdir /mnt/FTP chmod a+w /mnt/FTP
Write the ftpd.conf file:
cat <<EOT > /etc/ftpd.conf umask all 022 modify guest chroot GUEST /mnt/FTP/ EOT
Allow the anonymous user to connect
echo 'anonymous allow' >> /etc/ftpusers echo 'ftp allow' >> /etc/ftpusers
Create the FTP user
niutil -create / /users/ftp niutil -createprop / /users/ftp uid 502 niutil -createprop / /users/ftp gid 501
Restart the FTP server (this is the only way I know how short of restarting the system)
launchctl unload /System/Library/LaunchDaemons/ftp.plist launchctl load /System/Library/LaunchDaemons/ftp.plist
Once this is done you can browse to your Apple TV, for example, from Windows Explorer by entering ftp://your.appletv.ip/. You will be taken directly to the /mnt/FTP/ directory, allowing you to drag and drop files across directly. I found this faster (no encryption) and easier than using SCP, plus most OS's have an integrated FTP client these days.
