I upgraded to Lion and now there is no FTP setting in System Preferences
By default now, Apple has disabled FTP in OSX Lion, even if you had it turned on before upgrading.
You can enable FTP in Lion still by doing the following steps:
1...Open a terminal (Applications->Utilities->Terminal)
2…Type in (OR copy/Paste)
sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist
If you'd like to turn off FTP again, run Terminal and type:
sudo -s launchctl unload -w /System/Library/LaunchDaemons/ftp.plist
First things...
A few hints to start:
Its always a good idea to turn off your iPhone or iPad and then turn it on again. This fixes a lot of issues with networking and is a good first step to avoid frustration.
If MediaTransfer does not launch, or is locked, removing it and then downloading it again solves a lot of issues - but remember you will have to set it up again...
Test that your Firewall is not the issue
For MediaTransfer to connect from your iPhone or iPad to your PC, your PC needs to allow it to connect in the first place. Many issues with MediaTransfer are in fact firewall issues. Try turning off Windows Firewall and try MediaTransfer again.
If you use Windows Firewall:

My Pictures are cut off or my Videos do not work!
If you are seeing pictures where the bottom half is gray, its likely that your connection between MediaTransfer on the iPad or iPhone is being disconnected from the server.
Solutions:
Turn passive mode off in settings.
Make sure you are on the same wireless network as your computer.
A few users see this problem consistently when using active transfers. We have confirmed that this is an Apple bug in iOS and are working with them to get it fixed. We apologize if this is happening to you.
"No access to the camera roll was granted"

Tap the settings app.
Tap the General section.
Tap the Location Services section.
Make sure that the services are turned on for MediaTransfer.
MediaTransfer Says "Connection Refused"
If your iPhone or iPad pops up the message "Connection Refused" this could be because of one of two things:
Macs:
1... You have not turned FTP on. Click here to learn how.
PC:
1... You have not installed an FTP server. Click here to learn how.
2... Your Firewall is stopping incoming connections from your iPhone. This is a feature of your computer to help protect you against internet hackers. Click here to learn how to check this.
Detailed FTP Logging in OSX
To check what is happening in detail from OSX, you can do the following:
Inside of Applications on your Mac is a folder called Utilities.
Inside Utilities is an Application called Terminal. Open this application.
Now, in the window, type tail -f /var/log/ftp.log
This will show you the history of what has happened in the FTP server. Fire up MediaTransfer and watch to see any new messages. below is an example of the messages when an incorrect username or password is being entered by MediaTransfer:
Dec 26 17:19:55 MacBook-Pro ftpd[274]: connection from 127.0.0.1 to 127.0.0.1
Dec 26 17:20:01 MacBook-Pro ftpd[274]: FTP LOGIN FAILED FROM 127.0.0.1
A successful connection looks like this:
Dec 26 17:22:17 MacBook-Pro ftpd[332]: connection from 127.0.0.1 to 127.0.0.1
Dec 26 17:22:24 MacBook-Pro ftpd[332]: FTP LOGIN FROM 127.0.0.1 as jeremylaurenson (class: real, type: REAL)
Its also possible to turn up logging even further to view even more details of what is or is not going on, if you absolutely must:
Invalid URL Message
Mac Name in System Preferences:
This section should become unnecessary with release 2.0
If you get this message you likely have punctuation in your ftp:// path setting...
Dashes ( - ) ,ampersands ( & ) and question marks ( ? ) are usually ok, but most others should be removed.
Most common culprits:
Apostrophes should be removed: ' or `
Spaces in the computer name should be replaced by dashes ( - )
Spaces after the computer name should be replaced with %20
The best way to fix this is by checking the computer name name:
On a mac:
Open System Preferences, Select Sharing.
Note at the top of the screen: Computers on your local network can access your computer at: some-computer-name-here.local
Whats in mediaTransfer should match this name... you do not need to remove the trailing / that MediaTransfer adds
I still can't get my PC to talk to MediaTransfer!
90% of all the support requests we get are issues with Windows, Windows Firewall settings or Windows computer names.
If your PC is not cooperating, remember that MediaTransfer is free, and is not the culprit here... Getting FTP and Windows Firewall to cooperate is usually the issue: and we are happy to help.
Version 2.0 will make computer name issues a thing of the past, but you still need to work with your firewall..
If you are frustrated feel free to give up trying to make Microsoft like your iPhone... or check out how easy the Mac setup is... and be convinced to buy a Mac.
