====================================================================
ASNMP = ACE+SNMP++ Version 1.5
By Michael R. MacFaden mrm@acm.org, mrm@cisco.com
====================================================================
What is ASNMP ? ==> ACE+SNMP! aka Another SNMP API
HP's SNMP++ 2.5 freely available C++ SNMP class library
has been adapted to the ACE 4.2 Framework.
What was changed from HP version?
See src/ChangeLog file.
Is HP SNMP++ compatible with ASNMP?
It is neither source nor binary compatible. About 10% of the API has changed.
There have been API changes to make the interface more orthogonal
and to reduce implementation complexity such as consolidating constructors
with default formal values, and to remove some inconsistencies
with the HP interface as well as locking down valid() semantics, etc.
What platforms have the test programs been verified on?
Solaris 2.4, 2.5.1 using SUN C++ 4.1 compiler
Why use this version?
The SNMP++ version ships only for HP-UX and for Windows.
It is not very portable nor does it do a good job at checking
for out of memory exhaustion conditions (asn1.cpp). There is some great
code here. ACE needs an SNMP library to build NM type
communications applications. Hence ASNMP was born in my spare time.
How does ASNMP differ from SNMP?
Current version uses ACE OS Adaption layer. All memory
allocation is now consistent, uses ACE_NEW().
Standard ACE Debugging (ACE_TRACE) has been inserted.
ASNMP has less global namespace pollution by moving all non-class
functions into interface classes or made into static locals.
An agent inteface has been added (asnmp/sagent.h) so both agents
and managers can use this class library. A trivial agent
exists in ASNMP/agent/
X11 GUI support removed from this version since this is
not the place to include GUI support in the new world of
multi-threaded apps.
No ASYNC interface. In this version the ASYNC interface has been
removed. A new one based on class callbacks will be added in
the future. Use ACE Threads if blocking doesn't suit you.
SNMP V2c cmds (getbulk) has been hidden from the API until I
have an CISCO IOS agent that talks V2c to test with.
How to build this library?
Set ACE_ROOT and platform_macros.GNU per ../INSTALL file.
create libasnmp.a, libasnmp.so and then run the tests
Any Support for ASNMP?
As time permits from the mailing list.
Where to ask questions?
Please use ace-users@cs.wustl.edu mailing list or mrm@acm.org
NOTE: Please do not bother Eric Mellquist unless you are using
the original HP version of this library.
Where can I get the original HP SNMP++?
From ftp://rosegarden.external.hp.com:/pub/snmp++
What version of SNMP is fully supported?
SNMP Version 1 (RFC 1155,1157, 1215)
What about SNMP Version 2c?
V2c is defined in RFC 1901 - 1908
These bits are added to v1 code in this library: GetBulk PDU, Counter64
These bits are missing Inform (RFC 1905)
RFC 1903 defined new datatypes using existing SMI via macros.
These should be coded as if they were SMI datatypes to encapsulate
their behavior. V2c hasn't been deployed
What copyrights/legal requirements are required when using this code?
See ./COPYRIGHT
Does this really work?
See tests/ directory for the current test reports (purify/purecov/...).
Any Future Plans?
The ASNMP library will be improved for performance and made to use
higher level design patterns. Hopefully it will be used as a
vehicle for grad students to learn something about network mgmt
code work related distributed programming.

SNMP++ For UNIX Source Code and Examples:
====================================================================
Included within this package can be found the source code and
examples for SNMP++. The following represents the directories which
are included within the compressed tar file and their contents.
For more details on the API , please refer to the API specification.
This library is a complete implementation of SNMP++ and does not
require other SNMP libraries to be present.
