The /var/yp directory should now contain two newfiles and a folder. The passwd file is just like a typical password file created using thecustom master.passwd that we created for our NIS server. The ypservers file alsocontains the names of all master and slave servers for the domain.A directory named example-domain (which is the same as the domain name on yoursystem) containing NIS server's database files is also created with the default values.Now you can start your NIS server by running appropriate rc script manually, or byrebooting the server:# /etc/rc.d/ypserve start[ 257 ]
Network Services—Local Network ServicesSummaryFreeBSD offers a sound platform for local network services. In this chapter welearned to deal with a few of the local network services and protocols—DHCP, TFTP,NFS, SMB, SNMP, Printing, and NIS/YP. FreeBSD provides some of these servicesas built-in, while the others require the network administrators to configure themseparately using the built-in utilities (such as NFS).DHCP describes a means by which network devices access network configurationdetails from the server for communication. This section covers dhclient(8) ,andISC DHCPD daemon and its configuration. TFTP is a simpler version of FTP andrequires the inetd server to run. NFS is a client/server protocol used for filesharing for *nix operating systems. Samba implements SMB protocol, and is usedfor interface in Microsoft environments. SNMP monitors and controls the networkdevices. This chapter discusses the two open source SNMP utilities—Net-SNMPand bsnmpd. FreeBSD has its own print spooler daemons—lpd and CUPs. The finalservices that this chapter discusses are NIS, where a group of workstations share aset of configuration files.[ 258 ]
