Do not generate any NIS maps, as these already exist on the master server. Any firewalls between your machine and its NTP peers must be configured to allow UDP packets in and out on port 123. ntpd reads /etc/ntp.conf to determine which NTP servers to query. To configure the less important servers, replace the old +::::::::: on the servers with these lines: The corresponding lines for the workstations would be: NIS supports the creation of netgroups from other netgroups which can be useful if the policy regarding user access changes. If the format on a host needs to be edited to match the one being used in the NIS domain, the login capability database must be rebuilt after saving the change: The format of passwords for existing user accounts will not be updated until each user changes their password after the login capability database is rebuilt.

The crossmnt option is required to share directories that are sub-directories of an exported directory.. (If a file is owned by root on the server, for example, what owner is that on the client?) Many of the daemons which can be managed by inetd are not security-conscious. The File Transfer Protocol (FTP) provides users with a simple way to transfer files to and from an FTP server. Once ntpd_enable=YES has been added to /etc/rc.conf, ntpd can be started immediately without rebooting the system by typing: Only ntpd_enable must be set to use ntpd.

Using the above examples, the line might look like. The default administrator username is cn=config. The configuration of the lab will be as follows: If this is the first time an NIS scheme is being developed, it should be thoroughly planned ahead of time. The use of TCP Wrapper increases the latency of the NIS server. This determines which port inetd listens on for incoming connections to that service. Domain Name System (DNS) is the protocol through which domain names are mapped to IP addresses, and vice versa. WebGathering troubleshooting information from RHEL servers with the sos utility Since 1992, Samba has provided secure, stable and fast file and print services for all clients using the SMB/CIFS protocol, such as all versions of DOS and Windows, OS/2, Linux and many others..
