Comment 4 for bug 329522

Mark, the followsing command will always fail -
   sudo kcmshell4 fileshare

For it to succeed you must use kdesudo instead such as -
   kdesudo kcmshell4 fileshare

and it should succeed.

When using Dolphin to share a folder, if you don't have kdenetwork-filesharing then nothing will happen after you type in your admin password. You will also need to install the samba package in order to successfully share a folder using SMB.
