Me too!  Though to be honest, we never expected OpenSNMP to catch up
to Net-SNMP.  Regardless of whether OpenSNMP is better or not, it
would have to achieve greater development speed than Net-SNMP to
eventually catch the feature set which is rather huge at this point.

When we make decisions about what to use, we try to pick the best
project for each job.  Sometimes it's one, sometimes it's another....

Re: [Opensnmp-users] Opensnmp-usersOpenSnmp v NetSnmp

[Brendan S. <Br...@Br...>]

Thanks again Wes.  I will probably choose Net-SNMP of OpenSNMP for the 
following reasons.

    * SNMPv2c & SNMPv1 - some large organisations have a large install
      base of v1/2 monitoring software.
    * Larger install base => critical bugs are noticed and fixed earlier.
    * New python interface in 5.4 release :)

I would liked to have chosen OpenSNMP because it sounds like it has been 
engineered from the ground up to be more modular, etc, with proper use 
of C++ :)  I understand it is not as mature as net-snmp, but 
unfortunately it lacks a few features and is not a very active project.  
I hope you can get some proposals and funding together to take OpenSNMP 
to the next level to be as functionally complete as net-snmp.

I have some net-policy questions but I'll ask on the appropriate mailing 
list.

Thanks again.
Brendan.

The SNMPv3 architecture describes how to make a SNMP engine modular
according to the pieces that are described in RFC4311.  That
architecture is just "one" way to do it and is not "the" way to do
it.  SNMPv3 in Net-SNMP is completely compliant with the wire
protocol, but doesn't exactly mirror the "example" internal
architecture described by RFC4311.  Specifically, the dispatcher and
the message processing are not quite as separated as that document
describes.  The security modules, however, actually are.  But there is
no downside to the implementation with respect to supporting the
protocol.

The OpenSNMP stack, on the other hand, was actually created to *test*
the architecture described in RFC4311 to make sure the RFCs weren't
missing anything important (the work was done during the time the
standards were being prepared and it was a double check on the
standards documents).

BS> Are all SNMPv3 functions available, or does net-snmp provide more?

All SNMPv3 functions are available.  However, Net-SNMP has more
transports (tcp, for one) available for it too...  Both support IPv4
and IPv6 though.

Net-SNMP has a few more experimental SNMPv3 plugins though (the
kerberos security model, etc).

Also, by the way, OpenSNMP only supports SNMPv3.  It does not support
SNMPv2c or SNMPv1.

It works well because we use a number of class hierarchy features that
allow easier reuse.  Net-SNMP is filled with function pointers, which
works really well, but many people have a harder time understanding
than passing objects around instead.  Both work perfectly well,
actually, and I'd even suspect that Net-SNMP might be faster but again
no speed tests have been done.

Net-SNMP's agent is very very well tested and we simply haven't had
the funding to make OpenSNMP's agent as robust.  It's not that we
didn't want to, it entirely has to do with what we had funding to work
on.  We have needed the client side code more lately, so it's received
more attention.  It's as simple as that.

None of the above.  The goal was to produce a different package which
was written from the ground up to test the SNMPv3 specifications.  The
same project was responsible for putting in the SNMPv3 code into
net-snmp as well, actually (there were two phases to the project; the
first was to retrofit an older package and the second was to do a
study from the ground up testing the specification itself).

BS> Was net-policy the motivation or just the catalyst for OpenSNMP?
BS> What other motivations have I missed?

Net-Policy was actually a different project that came around after
OpenSNMP.  We simple used OpenSNMP as the SNMP stack within the
management framework of Net-Policy (which is one of the reasons, as I
said above, why OpenSNMP's management side code has gotten more attention).

If there was a wiki template somewhere, then it would be easier for

I'm curious to know why the agent has been a lower priority.  Maybe the 
demands of something like net-policy (eg. multi-threaded client 
application) was the catalyst and motivation, and that net-snmp was more 
than adequate as an agent?

I understand that they are independent projects, but I guess I'm 
interested in the motivation for writing OpenSNMP rather than 
using/modifying Net-SNMP.  Whas it to:
* improve functionality?
* improve performance?
* improve robustness?

Was net-policy the motivation or just the catalyst for OpenSNMP?
What other motivations have I missed?

Well, we actually haven't done a comparison between the two as far as
performance, etc.

OpenSNMP was designed from the ground up using a threaded C++
architecture that is completely modular and compliant with the SNMPv3
standards architecture.  Net-SNMP's SNMPv3 code, on the other hand,
was an add-on and isn't thread safe (that being said, it's very
heavily used).  (net-snmp supports an asynchronous call back mechanism,
though, that sort of provides some of what you'd get with threads).

OpenSNMP isn't heavily used, but we do use it ourselves in the
net-policy project (also a sourceforge project) for the management end
and it functions very well there.

We haven't done any speed comparisons between the two, though (but if
someone did, we'd love to see the results).

Nope, there isn't and yes it'd be nice!

BS> In general I see the move to C++ as a good thing, from a software

C++ has its ups and dows, just like C!  I think it worked really well
for the OpenSNMP project, but we did a lot of advanced design that
made it work well.

BS> I think there are Perl interfaces, but are there interfaces to other

Only net-snmp has interfaces to perl and python (the python interface
is very new and only in Net-SNMP 5.4).

BS> Is the this project still active?

Yes, but not really really active.  We use it internally for some of
our projects and there are some other people that have used the stack,
but it doesn't hold the popularity that Net-SNMP has had.

BS> I note that OpenSNMP has been used for client side managment apps with

Yep.  Like Net-Policy.

BS> Is the OpenSNMP agent working?

It is "sort of" functional.  It does work, but really needs a lot more
work for it to be robust.

BS> If so, would it be considered robust and reliable for a network product???

I don't think so for the agent.  The management side code, however,
I'd say yes.

Nope.  They're independent projects.

[Opensnmp-users] OpenSnmp v NetSnmp

[Brendan S. <Br...@Br...>]

I have a product that uses NetSNMP-5.1.  I am looking at developing a 
next generation product and am wondering if OpenSNMP may be a better 
option than NetSNMP-5.3.  Any comments or views ???

Presumably OpenSNMP is a newer architecture, and since it is designed by 
some core NetSNMP developers (hi Wes & Co) , presumably it improves on 
some of the known deficiencies in NetSNMP.  Are my presumptions correct?

Is there a feature/status comparison matrix for OpenSNMP versus NetSNMP 
(various versions).
If not, a wiki page and table would be nice ;-)

In general I see the move to C++ as a good thing, from a software 
engineering viewpoint, if used appropriately :)
I think there are Perl interfaces, but are there interfaces to other 
languages, eg. python ??  What about using SWIG ???

Is the this project still active?
If so, how active?

I note that OpenSNMP has been used for client side managment apps with 
some success :)
Is the OpenSNMP agent working?
If so, would it be considered robust and reliable for a network product???

Is the long term goal for OpenSNMP to replace NetSNMP ???

Cheers,
Brendan.

[Opensnmp-users] Re: Opensnmp-users./configure errors on Debian Sarge

[Ravi J. <oh...@gm...>]

I did more research on the web and found this link[0] the last
paragraph drew my attention and it says:

"[snip.. ]. It seems
that different versions of BDB simply *cannot* coexist on one box, and
as a result, every OS has implemented its own custom solution to the
problem (renaming libraries, installing them in weird places, etc.)
It makes our ./configure system hellish."

So this could be the reason I have yet to bring this matter on Debian lists.

In the mean time I have patched the configure.in to use AC_TRY_LINK
macro to find the C++ bindings for Berkeley DB.  I have already
submitted a patch on the list[1].  I can now build opensnmp on Debian.

Hope this patch is useful for others.

Wes, thanks for you help in debugging this problem.

On Debian the test fails and config.log has the following:
configure:2877: g++ -o conftest  -I/usr/include -I/usr/local/include 
-L/usr/lib -L/usr/local/lib  conftest.cc -ldb_cxx  -lpthread -lcrypto

/tmp/ccYDVjEl.o(.text+0x11): In function `main':
: undefined reference to `db_version'

So, it is failing to find the function db_version from the db_cxx library.

On researching I found another macro AX_PATH_BDB[1] that can also look 
for bdb versions.  When time permits I'll try this macro or I'll try something 
with  AC_TRY_RUN macro and report back later.

I'm not sure that it accurately tests for inclusion of the C++
support, you're right.

When the configure script was written I didn't really want to see if
configure would support testing for C++ class functions or not, so I
simply tested for a normal C function in the C++ library.  This
function should exist in the db_cxx library so the test will
definitely work.  The question is whether it could be written to test
a C++ function instead, and whether we should do that.  However, as is
its not a bug though you could certainly argue it has a missing feature.

(Note that the db_cxx.h file is also checked for)

DbEnv::version but the AC_CHECK_LIB macro is checking for a C function
which is not defined in db_cxx.h.

Also, look in the config.log file which should show what the error

Hmm, you might try '--with-bdb=/usr/lib' or just not use
'--with-bdb' at all.

If the libdb_cxx library is in the library search path (I'm not sure
how this is handled in Debian, but ldconfig and /etc/ld.so.conf in
fedora), you should be able to run configure without the
'--with-bdb' option.

Another possibility is to use
'--with-ldflags=-L/exact/path/to/libdb_cxx/directory/' instead of
the '--with-bdb'.

[Opensnmp-users] ./configure errors on Debian Sarge

[Ravi J. <oh...@gm...>]

Hi

I am trying to compile opensnmp and the configure script reports that I do not 
have BerkeleyDB installed.  I have the correct db installed (built with 
--enable-cxx).

I am executing configure with the following command line.
./configure --with-bdb=/usr

Output from configure:
[snip lots of test...]
checking for smiInit in -lsmi... yes
checking for EVP_md5 in -lcrypto... yes
checking for pthread_create in -lpthread... yes
checking for db_version in -ldb_cxx... no
configure: error: "libDB not found. get version 3.1 or higher from 
http://www.sleepycat.com/.  Make sure it is compiled with --enable-cxx."

Sorry for the slow reply,

The documentation is pretty poor, but the main binaries are in
app/cr/cr and app/cg/cg.  The cr is the Command Receiver otherwise
known as the agent or daemon binary.  The cg is the Command
Generator, a tool for doing snmpget's, snmpgetnext's, etc....  Run
cg --help or cr --help for a list of commands.  

The cg has been developed more recently than the cr so it is a bit
more mature.  Particularly the libcg has been used to allow other
applications to send/receive SNMP traffic.

Configuring the cr can be a bit convoluted.  The script
app/cr/snmp-db-init is the configuration that we usually use for
testing purposes.  You can see that it's using direct OID values as
input to some tools in tools//snmp-db-add/.

Another place worth looking through is the test/ directory.  These
are shell scripts that call app/cr/cg and app/cr/cr to test that
simple commands work.  (some of the scripts also are used to test
against a different SNMP stack, netsnmp, www.netsnmp.org).

Given your needs, I probably wouldn't use OpenSNMP.  My first
suggestion would be NetSNMP (also on sourceforge).  Although, partly
this suggestion is because NetSNMP is the SNMP package I am next
most familiar with.  It is more stable than OpenSNMP.  The Solaris
support is better (I don't think OpenSNMP has ever been compiled on
Solaris or SUN) and the documentation is much better.

It has a mib compiler, mib2c, but it only creates a template.  You'd
have to fill in the details (C code). 

http://www.netsnmp.org/  is a good place to start.  Particularly the
FAQ, Documentation and Mailing Lists links.
