Here's a summary of Van Jacobson's specifications for data
transmission in TCP protocol that I requested a while ago.  There are
two different specifications: RFC 1144 (Compressing TCP/IP Headers for
Low-Speed Serial Links) and RFC 1323 (TCP Extensions for High
Performance).  RFC 1323, the info I was looking for in particular,
talks about TCP window scale option, round-trip time measurement, and
protection against wrapped sequence numbers.  Also, SIGCOMM 88
Proceedings was meantioned as having easy reading for Van Jacobson's
family of TCP congestion control algorithms.

I would like to thank the following for their help.

I am very interested in running SLIP, and I wonder if anyone could
help me with a couple of very basic questions:

Is there a FAQ for SLIP available for FTP?

Where could I get SLIP for a DECstation or an IBM RS/6000?
(Commercial, PD, source, binary, *anything*)


Please reply by email to BARR@SILVER.LCS.MIT.EDU, because I cannot get

I'm not sure about this, but I think we had a similar problem some
months ago and it turned out to be the phone company that was shutting
off the line every 3 or 4 days. 

We were using a couple of T3000s. (Not anymore though).

Subject: Help with IP configuration
Date: 21 Aug 92 07:24:48 GMT
Organization: Network Architecture Consulting

I have a question about IP configuration for the following.
Please note that the IP addresses are not the actual ones used.
These Class C addresses were used just to depict the situation
at hand and is used solely to illustrate a point.

We have a production net and a training net. A SPARCstation 2 (zeus)
is acting as a gateway between the two nets.

We want the production network to have IP access onto the training net
but we do not want any traffic from the training net to be able to
access the production net. i,e, we want the production net to have
IP access to both networks but we want to limit training net so that
it will not traverse the production net.

The following diagram illustrates this:

                                                PRODUCTION NET

                                                TRAINING NET

Can any netters offer any solutions that will solve this problem ?
For right now, we are using a Sun SPARCstation 2 as a gateway machine
but eventually we will be getting a router.

In the interim period, we need to do some kind of IP filtering.

Please email me your responses because I do not access the newsgroups
often.

Thanks !

A quick and dirty technique I've seen used effectively is to take any
CPU benchmark (the simpler the better, so Drhystone is fine), and run
the benchmark with various simultaneous forwarding loads.  The
variations in what the bencmark reports can be attributed to the
forwarding load.  After calibrating the benchmark to the local machine,
you can have the forwarding load expressed in units of fractions of a
machine.

I'm looking for a "pass-through" archie client that'll work in
a firewalled network.  (By "firewalled," I mean that only one
system in our network is directly on the Internet, with packet
filtering activated to allow only specified packet types to pass
through to other hosts on the network.)

We've implemented pass-through ftp and telnet, so users on other
network hosts can access the outside world from their own
systems, and would like to provide similar access to archie.
(We know about accessing archie via e-mail, of course.)

I presume that we could set up our own archie server locally
if this is the only way to do what we want.

Thanks.

Hello,

We are having a slight problem with our tcp-ip system.  We are
useing FTP softwares version of tcp-ip and also AT&T's version
of enhanced win386 tcp-ip.  Recently we have experienced the following
problem:

During a successful telnet connect, a unix application program is
executed. This program runs for a time.  However, at various times
during the telnet session the line is dropped and the following
message is received on the AT&T enhanced win386 tcp-ip side.

	"telnet: can't ipop".

Could someone please tell me why this message pops up and how to
fix the problem?

Thanks in advance.

Dennis

There are two separate problems here, neither of which relates to
SA records:

1.  the terminal server should provide all 32 ports on the same 
    Internet address, so that you don't have one "busy" and the
    others not.

2.  PCTCP should try ALL addresses and not just the first one.  There
    are plenty of PC-based TCP/IP packages.  Perhaps you should consider
    trying another one?

SA records will work around this problem, but bear in mind that it is
a workaround and not a solution.

   I think "navy.mil" is only a placeholder in the root servers, i.e
   there are no global navy.mil nameservers.  These exist one level down.
   For example, my domain is dt.navy.mil, and if you query the root for
   that, you will find "glue" nameserver records pointing to that domain.
   Hence looking up, for example, oasys.dt.navy.mil from the root should
   lead to my nameserver and to successful name-to-address resolution.

This isn't possible on most unix systems.

On some systems (DEC's Ultrix, MIPS RISCos, CDC EP/IX and maybe some other),
there is some way to configure the way the resolver libs does their lookup.
/etc/svcorder, or /etc/vis.conf

But the real solution is to register all of your IP Addresses with a
nameserver!!!

Every additional network number advertised on the NSFNET backbone
represents
an additional memory load on every backbone router.  Why do you have
these
hundred of Class C networks?  Why not just use subnets off you Class B
nets?
The routing table explosion is the most serious short term problem of
the Internet
and if everyone was allowed to put in hundreds of net numbers, the
Internet would
collapse in a matter of months.  Things will get a bit better when
CIDR is implemented,
which will allow groups of nets to be represented by one entry under
some circumstances,
but it really won't be solved without the adoption of a new network
level protocol.
That's why there is all this work on IP7.

Several other people told me this, so I went ahead and ran some tests for
the particular second-level domain in question (noarl.navy.mil). 

$ host -t any noarl.navy.mil c.nyser.net
Using domain server:
Name: c.nyser.net
Address: 192.33.4.12
Aliases:

noarl.navy.mil NS TURNER-JOY.NOARL.NAVY.MIL
noarl.navy.mil NS MADDOX.NOARL.NAVY.MIL
$ host -t any noarl.navy.mil ns.nic.ddn.mil
Using domain server:
Name: ns.nic.ddn.mil
Address: 192.112.36.4
Aliases:

$

Note that one root server has information about this domain, another
does not. Inconsistency between the root servers. It is clear that this
is where my problem is stemming from.

"nslookup" skips the /etc/hosts file completely and goes straight to the

This may well be because you've got some IP addresses already cached.
I just checked again, at least two root servers (c.nyser.net and 
ns.nic.ddn.mil) return no information when queried for NS records 
for the navy.mil domain (or, for that matter, when queried for ANY information
on navy.mil). My question stands: what is going on with this domain?

Does anyone know what happened to the navy.mil domain? Even the root
servers no longer seem to have any information about it. Naturally
this means all mail sent to hosts within the Navy is bouncing with
a host unknown error.

I exchanged several e-mail messages with someone in the navy.mil domain
yesterday, 8/18/92, without any problems.
