ESnet provides Internet Protocol Domain Name Service to the ES community
through two separate name servers, DNS-WEST and DNS-EAST. These
name servers provide the primary IP address translations for the
es.net domain. In addition, either server can be queried to resolve
IP address translations for any IP host on the Internet.
In addition, these machines provide secondary name service for
many of the ESnet sites. Employing this functionality, sites can
off load many name server queries destined for their local name
servers to DNS-WEST and DNS-EAST. This procedure has the advantages
of providing a backup to a site's name server while reducing its
load.
DECdns is a DECnet/OSI network-wide service that makes it possible
to use network resources without knowing their physical locations.
Users and applications can assign DECdns names to resources such
as nodes, disks, and files. The creator of the name also supplies
other relevant information (such as the resource's network address)
for DECdns to store. Users then need only supply the name, and DECdns
will act as a lookup service, providing the rest of the data when
necessary.
The OMNI namespace has been created to support the transition
to DECnet Phase V within the DECnet Internet. ESnet supports two
root DECdns servers within the ESnet portion of the DECnet Internet
(ESnet-DECnet). As ESnet sites bring up DECdns servers, they are
added to the OMNI namespace.
The purpose of the Internet's Network Time Protocol (NTP) is to
synchronize the clocks on multiple networked hosts. Redundancy and
sanity checking are features of the protocol. ESnet provides several
stratum-1 time servers, each with a radio clock served by the U.S.
time standard broadcast from Fort Collins, CO, by NIST (National
Institute of Standards and Technology). NTP software is available
from ESnet in the directory Public-Domain.
ESnet operates an experimental Kerberos Version 5 Authentication
server. Kerberos provides a strong form of user identification,
and use of Kerberos can eliminate the need to send passwords over
the Internet.
