SAMBA: smbd, nmbd and winbindd
Samba is comprised of three daemons (smbd, nmbd, and winbindd). Two services (smb and windbind) control how the daemons are started, stopped, and other service-related features. Each daemon is listed in detail, as well as which specific service has control over it.

The smbd server daemon provides file sharing and printing services to Windows clients. In addition, it is responsible for user authentication, resource locking, and data sharing through the SMB protocol. The default ports on which the server listens for SMB traffic are TCP ports 139 and 445. The smbd daemon is controlled by the smb service.
The nmbd server daemon understands and replies to NetBIOS name service requests such as those produced by SMB/CIFS in Windows-based systems. These systems include Windows 95/98/ME, Windows NT, Windows 2000, Windows XP, and LanManager clients. It also participates in the browsing protocols that make up the Windows Network Neighborhood view. The default port that the server listens to for NMB traffic is UDP port 137. The nmbd daemon is controlled by the smb service.
[note: My samba box did not appear in samba browse lists from clients after a bootup. It seems my nmbd does not start up. So manually start service nmbd. Seems to be some bug in Ubuntu. My cure: manual start]
The winbind service resolves user and group information on a Windows NT server and makes it understandable by UNIX platforms. This is achieved by using Microsoft RPC calls, Pluggable Authentication Modules (PAM), and the Name Service Switch (NSS). This allows Windows NT domain users to appear and operate as UNIX users on a UNIX machine. Though bundled with the Samba distribution, the winbind service is controlled separately from the smb service. The winbindd daemon is controlled by the winbind service and does not require the smb service to be started in order to operate. Because winbind is a client-side service used to connect to Windows NT based servers, further discussion of winbind is beyond the scope of this manual. [from]
Netatalk: afpd, atalkd, …
Netatalk is a free, open-source implementation of the AppleTalk suite of protocols. Including AppleTalk (ATalk), Apple Filing Protocol (AFP), and Printer Access Protocol (PAP). It allows Unix-like operating systems to serve as file, print, and time servers for Macintosh computers.

afpd — Apple Filing Protocol daemon
cnid_dbd — implement access to CNID databases through a dedicated daemon process
cnid_metad — start cnid_dbd daemons on request
Not running on my box:
atalkd — AppleTalk RTMP, NBP, ZIP, and AEP manager
papd — AppleTalk print server daemon
timelord — Macintosh time server daemon
Avahi
Avahi is a free zeroconf implementation, including a system for multicast DNS/DNS-SD service discovery.

Nfs
Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed.
