Topic: - TAC-NEWS SERVICE
- MILNET/ARPANET HOST AND TAC ALIGNMENT LIST
----------------------------------------------------------------------
TAC-NEWS SERVICE
A news service for TACs has been installed. This service will be used
to inform TAC users of important changes in the ARPANET and MILNET, as
well as for TAC-specific notices. To reach this service from a TAC,
use the "@n" command to the TAC and the connection will automatically
be made. The user should then log in with username "tacnews" or
"tac-news" (no password required). The tacnews program will scan a
mailbox of notices in reverse chronological order when the "@n"
command is invoked.
MILNET/ARPANET HOST AND TAC ALIGNMENT LIST
In DDN Newsletter No. 31, dated 1 Sep 83, TAC users were advised that
they should know the net alignments of the TACs and Hosts which they
commonly use. This knowledge is especially critical following the
MILNET/ARPANET split (4 Oct 83) and the two test days preceding it
(8 and 15 Sep 83). A complete list of TACs and Hosts on each net will
be placed in a notice available through the TAC-News Service described
above. All TAC users should obtain a copy of this list prior to
8 Sep 83.
TAC users are also reminded that they must use the complete internet
address scheme if they wish to connect to a host on a different
network from the TAC they are using. An example of this form of
address is: 10.1.0.40, where
10 is the network number of the host being accessed (10 for ARPANET,
26 for MILNET);
1 is the port number of the host being accessed;
0 is reserved and currently is usually 0;
40 is the number of the IMP to which the host is connected.
