After you modify a system file, cd to /var/yp and run make.
However, you need not invoke this command directly; a Makefile in /var/yp generates all the common NIS maps.Either map can be used to enumerate the entries in the passwd file.However, because hashing libraries do not preserve the order of records, there is no way to reconstruct an exact duplicate of the original file (unless it was sorted).There is one map (file) for each key by which a file can be searched.For example, in the domain cssuns, the DB files for the /etc/passwd maps might be The passwd file is searchable by both name and UID, so two maps are derived from it.This system causes a lot of problems, not least of which is that it is extremely insecure.
An intruder can set up a rogue NIS server that responds to broadcasts and either provides bogus data or delivers a denial of service attack by allowing binding and then blocking on actual requests.
A master server maintains the authoritative copies of system files, which are kept in their original locations and formats and are edited with a text editor just as before.
A server process makes the contents of the files available over the network.
Note that the servers are given in the form of IP addresses.
accepts hostnames, but these hostnames must then be resolvable at boot time (i.e., enumerated in the /etc/hosts file or resolvable through DNS).
Whenever a file is changed on the master server, the corresponding NIS map must be pushed out to the slaves so that all servers provide the same data.
