Where are the "Connect to Server" history and favorites stored in OS X?
Hopefully they are in a pList file somewhere as I'd like to sync them between computers using Dropbox.
They are in ~/Library/Preferences/com.apple.sidebarlists.plist in the favoriteservers dictionary.
I wanted to update this as I was looking and could not find an answer that worked On OS X El Capitan (10.11.5). I started poking around and I found them in a different location.
~/Library/Application Support/com.apple.sharedfilelist/ com.apple.LSSharedFileList.FavoriteServers.sfl
In response to the original question, you may be able to put this file in a DropBox folder and run an alias to the Library location. Not sure how it would work with multiple owners and permissions on the file as I don't use dropbox and haven't tested it.
