To: TCP-IP at BRL

While I'm in favor of the split, I'm disappointed that the best security
arrangement DCA could come up with was to forbid anything except mail
from passing through the gateways.  While people on the ARPANET probably
have no need to access anything on MILNET (except to send people mail),
I can see a need for a MILNET person to have access to the ARPANET.

Internet security is an important issue, not just for DCA but for the
rest of the world.  We at Bell Labs will have to address the same
issues, and were assuming a nice solution existed.  Sigh.  Off the top
of my head, I would think that internet packets could have the network
of origin validated to the extent that, say, MILNET could look at an
incoming MILNET packet stamped as originating on another MILNET host,
and be sure it really came from that host.  This can easily be done
at the gateway, by refusing to admit a MILNET stamped packet from
the outside.  Once this is done, the higher level protocols (ftp, telnet,
etc) could refuse to respond to requests from the outside, or possibly
require some additional confirmation (an extra password, a command
typed by the same user already logged into the MILNET machine, or a
phone call to a guard who would authorize the transaction on the orders
of the person initiating it).

I hope someone out there can come with something even better.  I'd really
hate to see mail be the only form of communiation between MILNET and the
outside - it would result in file transfer being done by mailing files.

Mike:

I disagree with a point you claimed in the last TCP-IP Digest
(Vol.1 No. 27).  You said "The additional trunking provided by
the split will improve the performance greatly".  I agree that
a given net (set of nodes) with more trunks will likely have better
performance than the same net with less trunks.  However, it is
not at all clear that after the split either net will be better
than the combined net was.  One fundamental argument for packet
switching is the resource sharing argument.  That applies to the
trunks too.  One big system should be better than two smaller
systems.  Sometime administrative concerns take priority over
performance concerns, though.

To:   POSTEL at Usc-Isif, TCP-IP at BRL

Hello,

1. At NADC we are presently working on installing UNIX 4.1 bsd and BBN's
TCP/IP and SMTP on a VAX for the ARPANET changed scheduled for 1 Jan 83.

2. I am interested in determining what programs are available for sending
and receiving ARPANET mail.

3. What are other sites with this environment (VAX, UNIX4.1 bsd, and BBN's
TCP/IP) using?  And what is a source for information on the programs?

                             Regards,

In response to the message sent  13 Dec 1982 1049-PST from NADC@USC-ECLB

Dan Tarrant:

BBN has mail programs running on the Unix systems there.  As you already
are getting the SMTP from them, you might ask about the user programs for
sending and reading mail too.

To:       unix-wizards at Sri-Csl, info-vax at Sri-Csl
Cc:       tcp-ip at BRL

We run the BBN/Purdue IP/TCP under 4.1bsd on a Vax-11/780 talking to an
ACC LHDH-11, talking to an ECU, talking to a 56kb DDS link to another
ECU at a far away IMP.  Our IMP sponsor says they will have trouble
supporting our connection since there are no diagnostic routines
running on Vaxes for the ECU's.  ACC (the ECU manufacturer) gives
the same story.  We have no spare PDP-11's around to try things out on.

My questions are:
Has anyone else run into this lack of diagnostic routines and
what did you do about it?  Has anyone else heard of the version
of RT-11 which runs on Vaxes in emulation mode, (if so, where can
I get it?) and since there is ECU diagnostic software which runs under 
RT-11, would this be a possibility for getting around the
problem?  Thanks in advance.

Thanks for the past digests.  I take it then that you have fixed the
expiration problems for news and we should see the digests come through
as material is available.

[ Yes, the USENET feed should now function properly.  -Mike ]

I noticed there is a file on some ARPA machine that is available for FTPing
that describes the current status of TCP-IP implementations, is there someway
I can FTP it from usenet or directly?  I run into this occasionally and it's
such a pain that I have got to figure out some general solution.

[ Sorry, if you are only a UUCP host, no FTPs.  I'll mail out files from
  the NIC for you if you ask, though.  -Mike ]

By the way, are there any other Cyber TCP-IP implementations other than the
Tek code?  We are running NOS 1.4-552.

Thanks a bunch for your help,

Chris

Subject: need software for Interlan card
From: NEER at Usc-Eclb
To: tcp-ip at BRL

I would like to know if anyone out there has a driver written for
the Interlan ethernet card for lsi-11s running the MOS operating
system.

Or, does anyone have any ethernet driver for lsi-11 s on MOS.

Does anyone have tcp/ip on a 68000?

Like to hear from any and all.

Subject:  Re:  FOUO on the ArpaNet, MILNET, DDN

It is my impression that DARCOM directed that FOUO may not be transmitted
over the ARPANET.  Of course such direction would apply only to DARCOM 
elements.  I have not heard that the DARCOM directive has been rescinded.

Regarding the FOUO designation, a recent DF suggested that it will be
redefined with respect to the Freedom of Information Act indicating that
material labelled FOUO contained information which could be deletable
under exemptions 2-9 of the FOIA.  A new AR 340-17, Chapter 4, is
supposed to be released and provide guidance for the application of the
caveat "FOUO".  AR 340-16, Safeguarding FOUO Info, was rescinded.

Cc:      Cerf at Usc-Isi, tcp-ip at Sri-Nic, tcp-ip at BRL

The following is the host-by-host througput breakdown for the
TCP-only days on December 13th and 14th.  Overall, the network
passed 28,446,350 packets, as compared to 31,802,350 packets on
December 6th and 7th, one week earlier.  This represents 89% of
the traffic on the 6th and 7th, but does not take into
consideration the larger number of packets required by TCP over
NCP. 

Since it takes some time to get NCP disabled throughout the net,
the statistics below list only packets sent after 01:00 on the
13th .  Thus, the grand total at the end is less than the figure
given in the previous paragraph.

Note that IMPs 3, 33, 35, and 36 had NCP enabled during the two
days, and that IMP 73 had NCP enabled on the 13th, and as a
result NCP-only hosts on those IMPs may show traffic.  This was
to allow the PLI hosts on these IMPs to work; it is expected that
the PLIs will not use link 0 by January 1st. 

*** following the total is used to mark any hosts that sent 0
packets on the 6th and 7th as well as on the 13th and 14th.  This
may mean that the host was just "off the air", rather than being
restricted to NCP only.
