Re: Please i need support

[Max]

Check the Cisco site and the manuals that come with the device and see
if your device has an embedded SNMP agent, if it does you can then run
commands to get information from it.  Read up on the commands you can
use at

http://net-snmp.sf.net/

Good luck!

RE: v3 informs - snmpd.conf

[Joan Landry]

I am now able to send v3 traps - but not able to send informs - I added
the -Ci to the trapsess line, where the engineid is the engineid of my
sending agent.

Do I need to specify in the engineid of the remote management station if
I am sending and inform? 
Thanks,
Joan

I notice "The difference is that SNMPv3 TRAPs use the engineID of the

remote application. This means that you have to create users in your
remote user database with a bit more care and need to create one for

  Did you create a "v3user4" with the appropriate engineID on the trap

  Also try starting your agent with the "-d" flag for messages in

RE: v3 informs - snmpd.conf

[Joan Landry]

I have tried to get v3 traps to work - and unfortunately have had no
luck.

I have used a v2 trap2sink in the past and so I know the basic trap
mechanism works in my system. 

For v3 I have the following set up in snmpd.conf:
authtrapenable 1
group groupV2usm  usm v3user4 
view readview included .1  
view writeview included .1  
view notifyview included .1  
access groupV2usm ""  usm  noauth  exact readview writeview notifyview 
trapsess -e  ENGINEID -l noauth -u v3user4 10.11.12.171 
createUser v3user4 

where ENGINEID - is the value I read from 
   engineIDLen = snmpv3_get_engineID(engineID, SNMP_MAXBUF);

I am not seeing any error messages. 
I usesend_v2trap(var_list) in my code to send the traps.
But the receiving station never get them.

Am I missing something?
Thanks in advance for any insight you may have on this subject!!

See the section of snmpd.conf(5) entitled "Notification Handling".
In particular, SNMPv3 notifications are configured using "trapsess".
You'll probably need to consult the relevant tutorial as well
(referenced in that man page section)

The config file directive will populate these tables appropriately.

RE: setting ifAdminStatus when interface cannot go up

[Lewis Adam-VNQM87]

Just to give some context to what I am doing: basically, we are looking
to use a cut-down version of the net-snmp agent code as one of many
tasks running on an embedded platform. The platform has a number of
interfaces, some of which (currently) cannot be controlled via SNMP.
What I was trying to work out was the appropriate way of handling a
(albeit not very sensible) request from an SNMP manager to set the
ifAdminStatus of one of the 'notPresent' interfaces.

Thanks again for your suggestions.

Adam.

You can run the perl tests e.g. as follows on a Unix system (assuming you

  Might also figure out where net-snmp is deriving ifAdminStatus on your
OS and seeing if you can peg it outside of net-snmp.

  I dug around ifOperStatus some time back and ended up forcing things
with "if up" and "if down" commands.  It was kind of kludgey but worked
in a pinch.

[Lewis Adam-VNQM87]

Thanks Ron.

I had a rummage through the net-snmp support for the interface mib but I
couldn't see much in the way of exception handling or cross-checking
with the value of ifOperStatus. Lots of "TODO" comments lurking in
there. Maybe it's regarded as an implementation-specific design decision
but I had hoped there would be some official guidance somewhere.

What exact steps did you perform to build net-snmp with the Perl modules and 
run the tests?
The recommended way is:

./configure --with-perl-modules ...
make
make test
make perltest
make install (as root)

  Probably means that nobody has done exactly what you asked...

  If I were interested in forcing ifAdminStatus values, I'd first
unbundle the source tarball and grep -r AdminStatus *.

  Doing that on my (5.4.1) system, I see potential pay dirt in:

net-snmp/net-snmp-5.4.1/agent/mibgroup/if-mib/data_access

The syntax for the snmpTrapdAddr directive is exactly the same
as the syntax for the command line.   If you can specify the desired
listening port(s) on the command line, then you can use the same
value in the config file.

using NetSNMP::agent with SNMP::MIB

[Joao Ferreira gmail]

Hello all,

in the past I've done agent extension by using C, mib2c, and compiling
in a MIB C module.

Now I'm facing the same task but this time in Perl. I will use
NetSNMP::agent to implement a sub-agent, registered on our private
enterprice OID/branch.

The speed at which I will be able to refresh all MIB data is quite
slow... so I'll need generic temporary 'in memory' storage for MIB
information. This temporary storage will be used to respond to GETs,
while some asynchronous process refreshes the 'in memory' values at
diferent frequency.

I'm considering adding in the SNMP module (SNMP::MIB hash) to help as a
temporary buffer for MIB values. It seems to be clean approach.(!?!)

Am I going right ? Am I to excpect any big issues when trying to
integrate the 2 modules... ? Or is this considered an incorrect
approach ?

Apreciate any feedback, apointers to documents, best practices..
Thank you
Joao

I would suggest that you pull the overall initialisation
   (snmp_sess_init()  through to init_mib())
and the overall cleanup
   (snmp_close() through to shutdown_mib())

out of this function, and invoke them once at the start/end
of your application.   That's the most likely cause of the leaks
that you are seeing.

Either would be fine.
There is no definitive  One Right Place  to handle this.

The main question arises over how to handle errors.

If you make the changes during the ACTION phase,
then you must be ready to reset the values during the UNDO phase
and be pretty darned sure you can do this successfully.

If you make the changes during the COMMIT phase,
then you must be pretty darned sure that you can assign the
new values successfully.


Only you can make the judgement over which is the more
reliable step in your particular scenario.

To many open files

[Daniel Stålnacke]

Hi,

I'm using snmp to read status once every secound from a device and after
about 10 min I get an error which say that I have to many open files. I have
tried to find the error and close about anything I can find, but the problem
remains.

Here is the code:
http://www8.cs.umu.se/~dv05dse/snmpCode.txt

and the error:
http://www8.cs.umu.se/~dv05dse/snmpError.txt

Can anyone see where the error might be and which file I'm not closing.
I call this function once every secound.

Don't configure any SNMPv3 access control settings.
It will then not accept any SNMPv3 requests.

how to configure net-snmp agent version at run time?

[chenwill]

hi,

 

If a package is built with v3, it means net-snmp agent can handle request of 
snmp version v1, v2c and v3.

how can I confiure it as v2c, just accepting v1 and v2c request at run time?

See the section of snmpd.conf(5) entitled "Notification Handling".
In particular, SNMPv3 notifications are configured using "trapsess".
You'll probably need to consult the relevant tutorial as well
(referenced in that man page section)

The config file directive will populate these tables appropriately.

Re: Howto setup netsnmp for proxying and failover

That's not a model of operation which the current agent supports.
The proxy module can forward incoming SNMP requests to a specified (single)
subagent,  but isn't designed to handle multiple redundant subagents
for the same request.   You'd have to implement this yourself.

I'd suggest you start with the existing proxy code, and extend it to:
  -  send the delegated request to multiple destinations
  -  accept the first response (as currently)
  -  accept and discard all following responses

I don't know how you'd want to handle receiving different answers from
the parralel proxied agents, but the above should be a workable arrangement.

What do you mean by "rregistering [a] manager" ?

There are two situations where the agent might specify a network address:

  -  acceptable sources for community-based requests
  (note that SNMPv3 access control is source-independent)

  -  notification destinations

Both of these can be configured via the snmpd.conf file, and this does
include support for IPv6 addresses.  See the snmpd.conf(5) man page
for details.


> If so, which MIB is used for that.


The (community,source) to security name mapping is not covered by any
MIB module - it's purely handled by the config settings.
   (There is a standard community MIB, but it doesn't take any account
of where the request comes from)

Notification destinations are handled by the Target MIB.

The SNMP-TARGET-MIB is not restricted to IPv4.
The target address is specified by the pair of objects
   (snmpTargetAddrTDomain, snmpTargetAddrTAddress)

These can handle both IPv4 addresses (using transportDomainUdpIpv4),
IPv6 addresses (using transportDomainUdpIpv6), as well as a series of
other alternatives.   See TRANSPORT-ADDRESS-MIB for a possible list.

That is correct.

Try reading the error message again - and look closely at what it
*actually* says, not what you think it says.
   (I'd missed this error first time round!)


> it seems like the copy_nword return null for some reason

No - copy_nword is correctly returning the address you specified.
But the trap receiver cannot open the requested port, because
it doesn't exist.
