biod[2] | Works in cooperation with the remote nfsd to handle client NFS requests. |
crond[1] | Time-based job scheduler, runs jobs in the background. |

fingerd | Provides a network interface for the finger protocol, as used by the finger command. |
ftpd[1] | Services FTP requests from a remote system. |
httpd | Web server daemon. |
inetd[3] | Listens for network connection requests. If a request is accepted, it can launch a background daemon to handle the request, was known as the super server for this reason. Some systems use the replacement command xinetd. |
lpd | The line printer daemon that manages printer spooling. |
nfsd[2] | Processes NFS operation requests from client systems. Historically each nfsd daemon handled one request at a time, so it was normal to start multiple copies. |

portmap/rpcbind | Provides information to allow ONC RPC clients to contact ONC RPC servers |
sshd | Listens for secure shell requests from clients. |
