Hello,
 I'm looking for the standardization documents describing XMP and XOM
 (ASN.1 stuff). Any pointers would be helpfuls.

There is no *semantic* significance placed on the order of the
components of the SET.  You can think of this as meaning that the
creator of an ASN.1 specification uses a SET to convey the notion that
the ordering of the components of the SET is arbitrary as far as the
application program is concerned, and that there is no significance to
the ordering, from an abstract point of view.

However, when it comes to encoding/decoding the SET, the various
encoding rules of ASN.1 (BER, PER, CER, DER) place differing
requirements on the order in which components of a SET are encoded.
BER imposes no restrictions at all, so the order of the encoded
components is entirely unpredictable ... a testament to the
flexability of BER.  All the other encoding rules of ASN.1 impose
requirements on the order in which components of a SET are encoded,
independent of the order in which they were defined in the ASN.1
specification.

>Or can one assume that the order in which the elements were coded
>by the encoding agent will be preserved when the deconding agent
>unpacks the ASN.1 structure?

In the case of all ASN.1 encoding rules other than BER, you are
guaranteed that the order in which the elements are encoded is the
same when decoded, since those encoding rules mandate a single way in
in which the components can be encoded.  However, in the case of BER
it is possible for you to encode data in one order, and due to the PDU
passing through a relaying application (which may decode and re-encode
it), the order in which the components were originally encoded differs
upon receipt.

To summarize, your application should never make any assumptions about
the order in which components of a SET are encoded.

Subject: Re: Question about the SET construct of ASN.1
Date: 29 Dec 92 17:31:14 GMT

The reason for my question is that in group communication,
we would like to have a format which is as closely aligned
to the X.400 IPM format as possible. But we still need
a way of referring to the individual links defined in
the heading. By link I mean such attributes in the heading
which refer to other objects, like primary-recipients and
replied-to-IPM.

After your advice, I will now propose the following construct.
Whether that construct will be liked by the other people
in the standards group is something we will see at our next
meeting, in Tokyo in the beginning of February.

LinkName ::= SEQUENCE { 
        ipmid-part      IPMIdentifier, - - - as defined in X.420
        link-type       INTEGER (authorizing-users(1), primary-recipients(2),
                        copy-recipients(3), blind-copy-recipients(4), 
                        replied-to-IPMs(5), obsoleted-IPMs(6),
                        related-IPMs(7), reply-recipients(11)),
        link-position   INTEGER (0<..MAX) DEFAULT 1 - -  position of link in
                        - - sequences of more than one of the same type

I think basically 0 and 255 are reserved values. The transport entity
standards themselves would specify their NSAP SEL value, or they would
be in the International Standard Profiles (ISP) - eg. GOSIP, etc.

1 is used to address a ISO 8073 (Connection Oriented Transport Protocol).

See above.

Their testing is done from the perspective of the ES, not the IS.
I don't know of any fully accepted IS-IS testers; an issue here would
be whether the IS-IS superset that include Internet support is relevant.

   I worked with the TP4 test system developed by National Computing
Centre in the UK, and distributed in the US by the Corporation for Open
Systems.  I believe alternative systems are available from TITN/Alcatel,
GSI Danet, and possibly IDACOM (now a Hewlett-Packard division) and possibly
Retix.  It also may be worth checking with Tekelec.

COS distributes an FTAM tester---I don't know if it still is the
same one we developed in house; I think maintenance may have gone
to NCC.  Check with Dick Hampton at COS in Falls Church, VA. (might
be Fairfax VA).
   Session, ACSE, and Presentation are usually not tested directly,
but as entities embedded under a protocol such as FTAM or MHS.  
Considering that many application service primitives directly map
to session or presentation, this is not an overwhelming problem.

When SPRINT was TELENET, there used to be a loose-leaf document
called the [GTE]TELENET X.25 Implementors' Guide.  It did give
guidance on buffer management, etc.  I don't know if it 
still is available, and it was about $1000 in the 1980s.
   Another, less obvious, is the conformance test suite,
ISO 8882-2 for the frame layer and ISO 8882-3.  This will give
an example of virtually every state transition, and a test for
it.  This standard will not help with internal implementation,
but it is a much better specification than the base protocol.
   I was the development team leader for the Corporation for
Open Systems' X.25 tester, and formerly network management
architect for TELENET.  Given this and other experience, I
would hesitate to start an X.25 implementation from scratch,
simply because the size of the task.  There are decent portable
software packages commercially available (e.g., Spider Systems).
I would tend to start with one of those as a base, and customize
from there. 
   Since I've done X.25 implementation, I would not personally
need a consultant during the implementation,but I would suggest
some source of advice for a first-timer.  An OEM software 
vendor may be able to give you enough support, or there are
qualified consultants.

Back in -87, we wrote a report on "Implementation of X.25 PLP in ISO 8802
LAN environments". Yes, X.25 on Ethernet! It probably wasn't a great idea,
but the report may give some useful implementation hints, at least if you
are considering a UNIX kernel implementation.
Drop me an e-mail if you would like a copy - I think we still have some left.

I wrote some code to get the ARP tables using SNMP. I start by doing a get-next
on mgmt_mib_ip_ipNetToMediaTable_ipNetToMediaEntry_ipNetToMediaPhysAddress, and
I look at the type of the returned variable. If it is STRING I know the unit
supports MIB-II so I use those variables. Otherwise I assume it does not and I
use the MIB-I at table.

I tested this against various boxes (nodes, routers, etc), and found that the
Cabletron MRXI 10Base-T hub, which supports MIB-I, appears to fail in its
treatment of get-next. It returns NoSuchVariable for the get-next I outlined
above.

Anybody else seen this? Does Cabletron know about it?

	I've tried running the snmp agents (snmp, snmp-midII and sun) with
snm-1.1 and I can't seem to get any response from the requested system.  I'm not 
even trying on a remote system, my request is for the same host I'm ruuning on!  
For example, if I use the "Set request" option from the host's glyph and select
"Get" from the request window I get "(no values retrieved)" for ALL possible
combinations of agent-group.  Same thing occurs when I run from the prompt say:
snm_cmd -a snmp-mibII -g system -n sysDescr -s, I get "no response from system".
According to the user manual, this means the snmp agent is not running, but I
know it's running.  What about the snmp.hosts file?  Should there be any special
settings for my host?  Aren't the default values good enough?  There is not much
information available on what the "read-community" and "write-community" field
can or should be and what they entail...

Any hint would be greatly appriciated!

Be warned that bugs lurk in many of the unsupported, freely available 
SNMP engines.

Make sure that your code properly ASN.1/BER encodes counters/gauges/timeticks
(i.e. the unsigned things) properly when the 32nd bit (the sign bit on 32-
bit integers) is set.  It should take *5* octets length do this, not 4 as in 
some code.

Also check that get next really works.  It should be able to take *any* oid, 
whether or not that oid represents a variable, and finds the sucessor (or 
end of the mib.)

Also check that your strings (e.g. sysDescr) are real NVT, i.e. that if 
there are multiple lines that the lines are separated by CR LF, not merely 
LF.  And don't send any trailing nulls.

The problem with the snmp.hosts file is that once you have 1 host
in it, you will have the define all other hosts too in the future. From
then on, no defaults apply anymore.

Are you sure the community name is the right one?

Yes, I've seen this.  I've reported it to Cabletron.  They say they are
fixing it.

The way that I observed the symptoms was to do a get-next query for one of 
the variables which is in the MIB-II system group, but not in the MIB-I 
system group (e.g. sysContact).  I received a noSuch in return rather than 
rolling over into the interfaces group (which did exist).
