Networking Applications

To view all available systems on your network, select <guilabel>Samba Shares</guilabel> from the main window.

To view other <acronym>ZeroConf</acronym> systems, select <guilabel>Network Services</guilabel> from the main window.

Accessing network shares

If the <guilabel>Enable Zeroconf network browsing</guilabel> or the <guilabel>Browse local network</guilabel> options are not selected, please select them now and press the <guibutton>Apply</guibutton> button.

In the left hand side of the <application>Network Settings</application> dialog, select the <guilabel>Zeroconf Service Discovery</guilabel> option.

ZeroConf Configuration

<acronym>ZeroConf</acronym>, or Zero Configuration Networking, is a system that automatically creates an <acronym>IP</acronym> network without special configurations or servers. This type of networking and sharing is by far the most simple and is targeted to users with little or no networking knowledge. <acronym>ZeroConf</acronym> allows a user to to connect to computers, networked printers, and other shareable resources on the network without configuring network settings by hand.

ZeroConf Networking

<acronym>NFS</acronym>, or Network File System, is a file system supporting the sharing of files, printers and resources permanently over a network. <acronym>NFS</acronym> is much more advanced and difficult than <application>Samba</application>. Considering <acronym>NFS</acronym> is a very extensive protocol for file sharing, this portion of the Kubuntu System Documentation will ask you to review the following sites for further information: <placeholder-1/>

For more information, further instructions, or advanced features of <application>Samba</application> please review <ulink url="https://help.ubuntu.com/community/SettingUpSamba"/>.

If you are using a Windows network, then <application>Samba</application> may be your choice and configuration does not require use of the command line. To start simply press <keycombo><keycap>Alt</keycap><keycap>F2</keycap></keycombo> and type <userinput>kdesu kwrite /etc/samba/smb.conf</userinput> and press the <guibutton>Run</guibutton> button. This will open the <application>KWrite</application> text editor. Navigate down just below the <guilabel>Global Settings</guilabel> section to where it says <guilabel>workgroup = MSHOME</guilabel> and change out the <guilabel>MSHOME</guilabel> to match your Windows workgroup. Save the file and close <application>KWrite</application>. The next step is to install <application>Samba</application>.
