I edited ftp.plist by using sudo nano in terminal, and I saved by control + O but after reboot, it changed again. How can I save the file?

We are talking about /System/Library/LaunchDaemons/ftp.plist I assume. Did you verify whether your changes were written to the file after leaving nano? – patrix Sep 24 '11 at 6:20
Do you not want the file to be modified once you edit it? – l'L'l Sep 24 '11 at 6:47
It was written well. Because when I quit terminal and open the file again, it was changed. But after rebooting, it changed like before it is edited. – Stan Pak Sep 24 '11 at 7:38

In Finder navigate to /System/Library/LaunchDaemons/ftp.plist

  1. File > Get info Command + i
  2. Tick the "Locked" box

The file should not change now when you reboot.

I cannot see the file in the directory like this. So I edited the file using Terminal. Is there any option for see all files? – Stan Pak Sep 25 '11 at 3:11
I solved this problem by changing built-in ftp server's port to 9221 in etc/services file. – Stan Pak Sep 25 '11 at 3:57
