Ashok,
I have now managed to get SNMPv3 with SHA authentication working. The
problem seems to have been that when I built Net-SNMP I had built it with
the following options. Changing the link type option from static to
dynamic fixed the problem - I don't know why this would work but it did.
I can send SNMPv2 traps succesfully and am now trying to send SNMPv3 traps
using Authentication and No Privac y with SHA being used for
Authentication. My code looks like the following:
my $host = '127.0.0.1';
my $agent = new NetSNMP::agent();
my $session = new
Hi,
I am trying to configure my Net-SNMP sub-agent to be an SNMPv3 agent with
SHA Authentication and no privacy. I have been succesfully running it as
an SNMPv2 agent up until now. My configuration is that I have a Master
Agent communicating with a Perl Sub Agent using AgentX and running on

Using MD5 instead of SHA also gives me an Authentication Error.

I have now been able to get MD5 to work. I've just realised that when I
run the agent that a file is created in my installation directory which
is c:/net-snmp as follows:
c:/net-snmp/snmp/persist/snmpd.conf
This file contains information about the usmUser and the EngineId.

rwuser guest authNoPriv
createUser guest SHA password
Even adding authNoPriv as above seems to make no difference. It works if
set to MD5 rather than SHA. I'm wondering if my OpenSSL has been
built/installed correctly as Net-SNMP needs openssl for SHA but not for
MD5.
Has anyone any
I am running a Perl Net-SNMP Sub Agent which communicates with a Master

Thanks for that. The sysUpTime seems to be OK now.

Bart,
Thanks for the patch. It seems to have solved the problem in sending
SNMPv2 traps which do not have any additional var-binds.
Only problem left is the sysUpTime issue.
Regards,
Ali
Please consider the environment before printing this email
I have some further questions/observations on this subject.
The reason that I have not been able to send my own Enterprise specific
trap is that it does not have any additional var-binds associated with the
trap i.e I want to send the trap with an empty associated var-bind list.
e.g Bart in
Fulko,
I understand your point that a LinkUp trap needs the additional ifIndex
varbind. I didn't understand why the example I had been given by Bart also
contained a sysDescr var-bind. My point is that I wish to send an
enterprise specific trap that contains no additional var-binds. How do I
Fulko,
I also tried to send my trap (oid 1.3.6.1.4.1.2257.11.1.1.0.0.9) without
any additional var-binds as an SNMPv1 trap and it worked. The problem
seems to be sending it as an SNMPv2 trap, SNMPv1 is OK.
As for the sysUpTime, each time I run the command the timeticks value has
incremented
Bart,
I don't believe that is the problem. The actual amount that the timeticks
increases between sending commands is correct, it's as if it's just not
been initialised correctly. It doesn't seem to be a case of dividing the
value by ten. Also, even rebooting my PC doesn't seem to have reset
I am trying to send an SNMPv2 trap from my SubAgent which can communicate
with an SNMP Manager via the Agent X master agent. I am running version
5.7.1 pre2 on Windows and trying to send traps to the snmptrapd daemon.
My code for sending the trap is as follows:
my $host = '127.0.0.1';
I have now managed to send out an SNMPv1 trap correctly using the
following code:
my $host = '10.50.80.197';
my $comm = 'public';
my $session= new SNMP::TrapSession(DestHost = $host, Community =
$comm, Port = 162, Version = 1);
Bart,
I'm definitely getting closer now. I can now send a linkUp trap from my
software using SNMPv2. My code looks like this:
my $host = '10.50.80.197';
my $session= new SNMP::TrapSession(DestHost = $host, Community =
public, Port = 162, Version = '2c');
$session-trap(oid = linkUp,
Bart,
Thanks. The patch seems to have fixed this problem.

Bart,
Thanks. I have now managed to get a Perl subagent built with 5.7.1 pre1

One issue I have is that I am doing an SNMP-Get request on a table row
that does not exist. How can I indicate No Such Instance? There are
error codes defined for the NetSNMP::Agent but I cannot

Thanks for that.
Your suggestion results in the snmpget request correctly indicating No
such instance currently exists at this OID.

modified) did output unknown var value type: 0 as a result of the

I'm trying to understand the release strategy of Net-SNMP. Once 5.7 has
been released, I understand there will be a 5.7.1 release that includes
patches. Looking at the diff file that you have sent these seem to be 5.6
patches to be merged into 5-7 patches. Was 5.7 created and released
Bart,
Thanks for that. That patch stops the script locking up and completes the
installation.
I'm still trying to work out whether I can use Perl on windows. As you
stated earlier embedded Perl has not been ported to Windows.

I should have said that I am using version 5.5 of Net-SNMP on Windows with

As an alternative method of using perl I am trying to do this using the

My understanding is that embedding Perl in Net-SNMP are the Perk SNMP
Extension modules from the CPAN website. Ideally I would have liked to
have used these, I hadn't realised they had not been ported to Windows.
However - even without the embedding Perl in Net-SNMP modules I should

What exactly is embedding Perl in Net-SNMP if it's not the Perl

Looks like my understanding was wrong.

further.

There is company firewalls so they are probably blocking the git
