PERL problem with mib2c

[Gary Clark]

Running net-snmp-5.1.2.pre3 release.
 
When performing the following
$ mib2c etherStatsEntry
 
It looks like the two expected templates get 
generated:
 
etherStatsEntry.c and 
etherStatsEntry.h
 
However I then see the following:
 
running indent on etherStatsEntry.c
C:\cygwin\bin\perl.exe (3996): *** unable to remap 
C:\cygwin\lib\perl5\site_perl\5.8.2\cygwin-thread-multi-64int\auto\NetSNMP\default_store\default_store.dll 
to same address as parent (0xEF) != 0xFF
    237 [main] perl 2196 
sync_with_child: child 3996 (0x5fc) died before initialization with status code 
0x1
    734 [main] perl 2196 
sync_with_child: *** child state child loading dlls
 
ok I think there is a conflict between versions of 
perl? However can I still assume the templates generated
are valid?
 
Any answers to this would be 
appreciated?
 
Cheers,
Garyc

Your path is wrong it doesnt know where you have installed the MIBS.
/usr/local/share/snmp/mibs is where the above can be found. Depending on
what OS
your running you may need to set environment variables such as MIBDIR and
MIBS=ALL etc
to find the above MIBS. You can of course examine the mib2c perl scripts
which are use to discover what you need
or refer to documentation on net-snmp web site.

Thanks,
Garyc

Re: perl(Term::ReadKey) error installing 5.1.1

[Gary Clark]

Yeh I had that exact problem yesterday. I am 
ensuring today that my Linux version of RedHat 9 is complete on my 
machine today.
I'm hoping that will resolve the issue and have all 
the .pm module etc. This is painful especially when I'm not sure if 
this is going to resolve
the problem.
 
I tried an earlier version of installation and only 
to "hit the obvious wall" of version mismatches. I will let you know how it 
goes.
 
Cheers,
Garyc

Version 9 and linux red hat installation problem

[Gary Clark]

Hello,

Reinstalled linux red hat version 9. Then promptly grabbed the
net-snmp-5.1.1.rh9.i686.rpm.

I then performed the magic:

>rpm -i net-snmp-5.1.1.rh9.i686.rpm

to get the below:

perl (Tk) is needed by net-snmp-5.1.1

I then grabbed the package Tk800-804.027.tar.gz. Performed the necessary
gunzipped and untar. Rebuilt the TK and performed
make install. All went a charm.

Then I tried again:

>rpm -i net-snmp-5.1.1.rh9.i686.rpm

to get the below:

perl (Tk) is needed by net-snmp-5.1.1

Anybody know what I need to do to get past this?

Cheers,
Garyc

UnLinked OID

[Gary Clark]

Hello,
 
Ok I read the FAQ on UnLinked OID and even though 
its a relevant definition I dont think 
it relates to the problem I am seeing.
 
I am basically building a simple table,populate all 
the object elements etc and then run mib2c.
It goes ahead and constructs the templates and 
kindly asks me to fill the functionality. 
 
When I alter a name of an element in the table and 
make the correct changes to the MIB. It then
throws out the complaint of UnLinked OID. When I 
revert back to the original change it then happily goes
ahead and regenerates the templates.
 
What I'm gathering its already performed some 
storage
and is getting confused when another another 
attempt is made to generate the code.
 
Where can I remove the stale objects?
 
Much apprecaited,
Garyc

Re: UnLinked OID

[Gary Clark]

Hi,

The below version will generate the templates i.e the .c and .h files.
However if after generating the templates
I want to change the MIB again i.e change tcpConnState name to
tcpConnNewState then I will see the UnLinked OID.
I think I need to remove some files just dont know where.

Much appreciated,
Garyc

walking snmpd

[Gary Clark]

hello,

I am running Linux version 9 with version 5.1.1 of net-snmp.

I have added and built the MIB and included it into the directory
/usr/local/share/snmp directory.
Generated the templates successfully and moved them into mibgroup and
created the top header with
the "config_require(mibfiles.c) etc".

Performed ./configure and performed make.

Ok I am using the snmpd -d to debug whats happenning. When I perform
snmpwalk -v 1 -c erlang local host .1.3.6.1.2.1.6.15

I see the the snmp daemon Receiving a get request and sending a response to
the local machine:

TCP-MIB::tcpOutRsts.0 = counter32: 2

Marvelous. Just what I expected. Ok when I try to do the same with myMib. I
see the snmp daemon receive
and send but I dont see anything on my machine. The snmptranslate for the
given OID works fine though.

Questions do I have to perform a set on an entry within the MIB prior to
performing the "snmpwalk" command?
Is there a stage I have missed?

Cheers,
Garyc

Generated templates

[Gary Clark]

Hello,

I have generated the templates using the mib2c command.
I initially chose to use the templates that contained tables which are
contained in internal memory.
When the agent dies...the tables die without any persistence.
Having tried out the get and set routines which work like a charm on the
tables on those tables.

I would like to use persistence for the MIBS and need some advice on this. I
would like to still use the
internal memory table generated code and simply add extensions to this code
so that I can add close a file.
Is there a standard procedure for creating persistence?

Thanks,
Garyc

cool totally cool

[Gary Clark]

Hi,

I was advised to stick with the current approach of generating template code
and filling the code out to get persistence to work.
Basically I can save the mib to a persistence file and reload the
persistence into the mib. When set requests are performed the agent updates
the mib and the persistence file.
Thanks for the advice I now have a mib loaded into the trees, matching the
contents of the persistence. Its so cool. I'm having one
of those rare engineering moments that what I'm doing is worthwhile.

Much appreciated,
Garyc

Merge changes?

[Gary Clark]

Hello,

After I have implemented the changes in the template code generated the I
realise that I need to add something to the MIB.
Can I just make the change to the XX-MIB.txt file and then make the changes
to the .c and .h files and rebuild?

Or are there additional bindings needed?

Thanks,
Garyc

Perform ps -A to see if the agent is running. How did you build the agent
V2,V1?

Policy for commiting mibs?

[Gary Clark]

Hello,

Is there a policy for commiting MIBS to persistence in net-snmp. At the
moment all SET actions are followed by a COMMIT.
I then cycle through the columns of the row and insert them into the
persistence file. Not really what I should be doing.
Only when a selected field is set (i.e FLAG_COMMIT) should I commit the
entries to persistence? I know this could
be a potential solution. However is that what is generally adopted and
accepted?

Much appreciated,
Garyc

P.S

This is so cool.

Re: subagent prob

[Gary Clark]

Hi,

1) Ensure that you perform a set operation on the oid prior to a get.
2) Double check you mib is correct.
 3) Ensure that the index value is included in you get operation.

Thanks,
Garyc

Being persistent with persistence

[Gary Clark]

Hello,

Ok I messed up somewhere. Just dont know where. I think its an environment
variable issue?
I have been using persistence. Extracting tokens and creating oids in my MIB
tree and all is well.
Then I did something which has caused my environment to change. I cannot get
persistence to load again.

Here is what I am doing:

./configure --with-mib-modules=psb_test
make

Everything builds fine and I can perform set and get requests on the oid. I
register the app handler
and create a function that should be called.

snmpd_register_config_handler("myFredToken",parse_func,NULL,NULL);


I manully modify the /var/snmpd.conf to contain:

myfredToken 1

I dont see my parse function being called. I enabled trace and saw that the
token is getting registered however no callback is made.
This is probably going to be blatently obvious to the net-snmp gurus, myself
a humble novice has been stumped.

However I think its my configuration environment. Likely SNMPCONFPATH
environment variable?

I use snmpconf -g basic_setup. This produces the snmpd.conf configuration. I
point the SNMPCONFPATH to /usr/local/share/snmp?

Is this OK.

If anybody can shed some light on this blind fellow much appreciated and
promise to return help if I can.

Cheers,
Garyc

Re: Being persistent with persistence

[Gary Clark]

Hello,

Ok I was on the right path. Basically I completely forgot the little trick I
did.

This is what confused me. I have two configuration files both called
snmpd.conf.
One is for persistence and one is for general configuration which is
produced using snmpconf -g basic_setup.
My SNMPCONFPATH was set to the point general at /usr/var/local/share. The
persistence configuration resides in /var/net-snmp.

I was manually inserting my token into the persistence file. Thinking that
it would be
read and my callback function would be called. Idiot, total idiot. The
callback function would only be called if the token resided in the
snmpd.conf file pointed to...yes you get it SNMPCONFPATH.
At some point I must of altered this environment variable to point to
/var/net-snmp and pick up the tokens.

The reason why I am doing this. Basically when the agent restarts I want to
pull the tokens from the persistence and re-create the oids.

The question begs. The SNMPCONFPATH points to the general agent
configuration. Should there be two configuration files?
I think there should just be one right?

Thanks,
Garyc

Ok what I do is keep a local copy of the set request data in an array. This
could easily be a linked list of objects. When a set request is made I check
a COMMIT flags in my MIB to see if that is set. If it is set when the commit
function gets called (following the set action) I then pack the contents of
the row into a message. This message is then parsed and columns extracted
and pushed into a
linked list/ vector. The store function is called and writes the linked list
into persistence. By doing this updates to persistence are passed to the
user and not when the agent is killed. Make sence?

Cheers,
Garyc

Re: configuring VLANS or multiple variable sets in one SNMP command

[Gary Clark]

Well I designed a VLAN on one of our routers and it worked. But that is not
what this user group is for. The set commands as far as I know access a
single oid within your MIB. But you could create your own SET request which
would use the individual SET requests? A wee' wrapper.
It shouldnt be that difficult to do. The applications provided for
snmptranslate and set etc are pretty cool.

MIB2c just provides the template code which us mere mortals have to conjure
our applications.

Cheers,
Garyc

Adding traps

[Gary Clark]

Hello,

I cannot at present get the traphandle to call the traphandle script.

At present I can run the snmptrapd and I have configured the snmp.conf to
receive traps.
I can see the coldStart trap being received but my script is not run.

Within the snmptrapd.conf file I added the following line:

traphandle .1.3.6.1.6.3.1.5.1 /usr/bin/perl /usr/local/share/snmp/cold.pl

The perl script runs fine by itself.

I have placed the snmptrapd.conf within the directory /usr/local/share/snmp.

I cannot see the cold.pl script being ran since no output from the script is
seen.

Have I got to set some environment variable? I am running the trapd using:

./snmptrapd -f -Le

Any ideas? I know this should be obvious? Just missing something

Cheers,
Garyc

Re: Adding traps

[Gary Clark]

Hello,

The problem I'm seeing is that the snmptrapd.conf I dont think is being
accessed due to the script not being ran.

The snmptrapd.conf: now contains the following which Dave recommended:

   traphandle .1.3.6.1.6.3.1.1.5.1 /usr/bin/perl
/usr/local/share/snmp/cold.pl

I then used the following "cold.pl" perl script:

#!/usr/bin/perl -w

print "At last the coldStart handler is alive!!\n";

sub getline()
{
while ()
 {
  my $line =$_;
  chomp ($line);
  print $line;
  }
}
sub main()
{
  getline();
}
main();

Simple. It accepts lines from STDIN and prints them out. This looks ok?
So if I dont see any output line I dont think the configuration is being
accessed.
Can somebody enlighten me on this? Is it an environment issue, if so how can
I determine this?
The snmptrapd.conf is located in /usr/local/share/snmp.

I'm running the trapd and it does receive the coldStart trap I just dont see
my script being ran.

Cheers,
Garyc

Re: Newbie : New MIB

[Gary Clark]

Hiya,

What I did when trying (still trying) to understand this baby was fill it
with trace. There are examples already in the code.
However run the snmpd agent with -d or -D this will dump allow you to see
some action. See the log file in /var/net-snmp/snmpd.log.

Providing you have built everything correctly you should be able to perform
snmpset and snmpget requests on the oid.
Note you need to fill the template code with your specific needs.
In its present state it will have the capability of allowing get and set
requests but may need embellishing.
But its upto to you to build the persistence and create your own data
structures to manage the contexts.

Thanks,
Garyc

Re: Adding traps

[Gary Clark]

Hello,

By turning on the debug trace on the trace:

snmptrapd -f -D -Lf dummy

I can capture all the dump.

I could then view the trace and saw that indeed the token "traphandler" did
get registered and a call was being made to my
handler. My perl script was handling the trap handler call incorrectly. But
of course.

Thanks,
Garyc

CLI for net-snmp

[Gary Clark]

Hello,

Does anybody know if there is a CLI (command line interface) application
that presents data in a better format than using the snmpget and snmpset
routines for linux?

I dont want to embark on writing an application if there is one that
currently exists. If anyone knows where I can access
an application that would help me alot.

Thanks,
Garyc

[Gary Clark]

Thanks Ted. I'm after and application which can browse and set . The mbrowse
is good for examination, but can it also set mib values? Any tools I can get
for free?

Thanks,
Garyc

Re: ucd-snmp 4.2.3 dies shortly after restart

[Gary Clark]

Robert,

You can add trace to your code. At least I found that invaluable when trying
to debug.
snmp_log is very useful for this. This will dump your trace to
/var/log/snmpd.log.
Have yet to build for debugger.

Thanks,
Garyc

Master Agent Design approach?

[Gary Clark]

Hello,

Ok built the agent (very dandy) works like a charm. The question I have is
where do I begin with the master agent?
Whats the approach? Any ideas would be useful?

Thanks,

Re: Master Agent Design approach?

My apologies terminology. In my design the snmp agent would be the subagent
on the line card. The master agent would be an NMS. What I would like to
know is the approach needed to design an NMS that can be used with the
agent? I hope that
sounds clearer.

Much appreciated,
Garyc

trap question

[Gary Clark]

Hello,

1) Start snmptrapd
2) Start snmpd
3) Perl script is fired and I dump the coldStart data to a file which is
what I expect to see.
4) Pull a link which has an associated MIB oid type of NOTIFICATION_TYPE
5) The link oid exists in the snmptrapd.conf file

I see that thesnmptrapd does indeed register with the correct callback
function for the link oid.

So if I set a value in the NOTIFICATION object should I see a trap being
sent?
Is there any stage I'm missing here? I gave the link oid the same type as
NOTIFICATION_TYPE.
Is there an example where I see this in action.

Thanks,
Garyc

Re: trap question

[Gary Clark]

Hi Dave,

> What do you mean by "pull a link" ?
My apologies. On our board we have optical fibers referred to as links. When
a link is pulled its state changes from IN-SERVICE
to OUT-OF-SERVICE. The oid associated with this link is of
NOTIFICATION_TYPE.

> Sorry - that doesn't make sense.
> NOTIFICATION-TYPE objects don't have values,
> and you can't SET them.

Ok thats the first thing cleared up. I thought I could just set a value and
a trap would be triggered.
Is there documentation or a code example of how I can generate a trap? How
do I trigger trap generation?

My apologies for the confusion. I misunderstood the usage of the
NOTIFICATION_TYPE.

Much appreciated,
Garyc

Re: trap question

Just imnplemented the traps into the agent. Works like a charm. I wrote a
perl script which dumps all traps.

Again they should seriously reward the support on this. No question.

Is it possible? I'm sure it can be done

[Gary Clark]

My beloved company has asked me to write another agent. Yep no rest for the
wicked.
They want me to write a net-snmp agent(A) that can send set and get requests
to another snmp agent(B) whilst agent(A)
can receive set and get requests from the NMS (which I contructed using
perl).
I went over some of the problems in my head maybe i.e agent configuration
file issues and using the application code examples in
net-snmp/Apps and integrating that into my agent might be the best approach?

Any ideas on this? Has anybody tried to do this?

Much appreciated,
Garyc

Packaging of snmpd

[Gary Clark]

Hello,

I have a couple of questions:

1) I want the snmpd executable to be self-contained and not dependant on
installation of net-snmp. Is this possible.
The snmpd excutable resides in nets-snmp5.1.2/agent/.libs and when excuted
when net-snmp has been installed
everything is starts correctly. When trying to run the snmpd on a separate
linux machine it crashed with the
underfined symbol "net-snmp daemonize".

Basically I want to make it very simple for the customer to install and use.

2) The snmpd.conf file is situated in /usr/local/share/snmp. If there is no
/usr/local/share/snmp then can the agent
 point to it using an environment variable. I know SNMPCONFPATH is a
way. However this gave me problems
 when trying to use persistence and was advised to not to set the
environment variable. Do I simply ask the user to create
 a directory /usr/local/share/snmp ?

Re: Packaging of snmpd

[Gary Clark]

Hello,

I rebuilt the executable. Yes it does build but it still contains shared
libraries.
'configure --with-ldflags=-Bstatic'.

The static flag does indeed gets added but the dyamic libraries are still
being pulled in and I can see them by performing an
' ldd'.

I looked at the rest of the static explanation.

NETSNMPDIR=/usr/local/build/snmp/full-clean-cvs-V5-1-patches
   NETSNMPCONFIG=$(NETSNMPDIR)/net-snmp-config

   NETSNMPBASECFLAGS := $(shell $(NETSNMPCONFIG) --base-cflags)
   NETSNMPINCLUDES := $(shell $(NETSNMPCONFIG) --build-includes
$(NETSNMPDIR))
   # base flags after build/src include, in case it has /usr/local/include
   NETSNMPCFLAGS=$(NETSNMPINCLUDES) $(NETSNMPBASECFLAGS)

   NETSNMPBASELIBS := $(shell $(NETSNMPCONFIG) --base-agent-libs)
   NETSNMPEXTLIBS := $(shell $(NETSNMPCONFIG) --external-agent-libs)
   NETSNMPLIBDIRS := $(shell $(NETSNMPCONFIG) --build-lib-dirs
$(NETSNMPDIR))
   NETSNMPLIBDEPS := $(shell $(NETSNMPCONFIG) --build-lib-deps
$(NETSNMPDIR))
   LIB_DEPS=$(NETSNMPLIBDEPS)
   LIBS=$(NETSNMPLIBDIRS) -Wl,-Bstatic $(NETSNMPBASELIBS) -Wl,-Bdynamic
$(NETSNMPEXTLIBS)


   STRICT_FLAGS = -Wall -Wstrict-prototypes
   CFLAGS=-I. $(NETSNMPCFLAGS) $(STRICT_FLAGS)

This replaces the standard Makefile section, which will used installed
libraries:

   NETSNMPCONFIG=net-snmp-config

   # uncomment this if you have GNU make
   #NETSNMPCFLAGS := $(shell $(NETSNMPCONFIG) --base-cflags)
   #NETSNMPLIBS := $(shell $(NETSNMPCONFIG) --agent-libs)
   NETSNMPCFLAGS=`$(NETSNMPCONFIG) --base-cflags`
   NETSNMPLIBS=`$(NETSNMPCONFIG) --agent-libs`

   LIBS=$(NETSNMPLIBS)

The below section in the Makefile? Which Makefile? The standard Makefile
section does not contains any of the definitions.
Do we have a set of static libraries I can use to replace the share
libaries? I'm using 5.1.2 for linux red-hat.

Much appreciated,
Garyc

Re: Packaging of snmpd

[Gary Clark]

Hello,

I managed to build my agent and run it. It still dies but I am tracking it
down exactly why.

Use:

./configure --enable-static=yes --enable-dynamic=no --with-mib_modules=psb

It appears to be ok for one of the tables initialisation etc. I will find
out in the next hour whats going on.
No shared libraries are pulled in.

Much appreciated,
Garyc

Re: Sending traps in another thread

[Gary Clark]

Yes,

I have sent traps in using a pthread. No problem. Are you trying to free a
PDU that has not been malloc?
Segmentation faults are usual candidates (using the the political term) for
bad memory accesses.
So your pointer may be invalid? Can you dump out what you allocate and what
you free? Again adding trace
is essential.

Much appreciated,
Garyc

Re: Sending traps in another thread

[Gary Clark]

Hi,

Wow! I'm blessed one of the gurus. Ok no problem.

>What platform are you using?

The OS platform is Redhat 9. Complete installation. If you do a partial
installation your going to hit all sorts of missing
libraries. Quite funny when you only do a regular installationnot.

> - What threading mechanism are you using?

I'm using Linux pthread. I'm not a fan of threads having seen the disasters
of misuse. But this seemed to be
an acceptable solution.

> The number of threads I use in my application. I link a library which I
know uses pthreads which performs alot of the driver
functionality to the hardware.
However the generated code produced using mib2c I wanted to keep pretty much
the same (to avoid additional headaches when changing mibs etc) so I created
global object that the table functionality directed requests to. Its within
this oject that I created threads. I have only two threads in this global
object. One to monitor link up and link downs and to invoke a trap when this
happens. Another to send a trap upon the completion
of a download or upload to and from the hardware. I dont want to block the
main thread so this was a good solution.

> Have you implemented any locking mechanism?

Standard pthread mutexs were used.

> Is your application an agent

Yes my application is an agent. Its controlled either from a perl script
which I wrote which uses Dave M.Towns Net::SNMP perl module. Its going to be
controlled by a browser which one of our guys are working.

>  Do you call init_snmp()/init_agent() in more than one thread?

never.

I would have to read the README documentation on threads. I am using the
pthread implementation and including the pthreadlib.

It was very easy to perform manual building. Using the notification example
you could figure out what was going on.
send_v2trap is what I am using.

Much appreciated,
Garyc

The download to the hardware device or upload can take time and didnt want
another request to be handled
so I use:

pthread_mutex_lock(&operationMutex)
   Download data to hardware device
   Send trap
pthread_mutex_unlock(&operatonMutex)

> thread? Where is the mutex set-up/locked in the agent?

The same type of mutex is used in other worker threads that is correct.
I am initializing the mutex in the main thread in my global object.

Download of Image to hardware

When a set request is received by the agent to download an image to hardware
a function call is made to download.
Within this download function I have the mutex to lock to prevent multiple
requests to download and then I spawn a thread that downloads the image to
the hardware device. Once complete the lock is disabled. The thread
resources are removed once the thread exits.


Thanks,
Garyc

This is what I sent out yesterday. Yes your both correct. The main thread
however is blocked as stated in the above text.

Re: Sending traps in another thread

[Gary Clark]

Well I've got running and I'm seeing no problems of conflict. No downloads
requests are handled whilst the mutex is locked hence
only a single trap is sent and only any one download requests is handled at
any one time.

Re: Sending traps in another thread

[Gary Clark]

The main thread spawns a thread. So there could be many threads. Each thread
calls a download function. But this downloadfunction has a mutex hence only
one thread at any one time can have access. I was going to have some
consumer-producer queueing but I got idle. Its ok. Produces threads but they
are all independant and are "serialised" when downloading.
Oh well cheap and ugly but less complex.

Cheers,
Garyc

Re: Packaging of snmpd

[Gary Clark]

Yeh thats true. Some OS linux share libraries are still pulled in
absolutely. But no share libraries from SNMP. I dont mind running
the agent on a linux platform. I just dont want to have to install Net-SNMP
in order run my agent.

Re: perl / multiple agents on same host, for same OID

[Gary Clark]

Robert is correct. I could forward an example of how I used the perl module
so you can gain an insight. Of course you need
some perl background to make head n tails of whats going on. But you should
get the gist of my sample code.
However I'm not going to support someone else agent driver. Absolutely not.
I try to keep it simple stupid if you get the gist.

Garyc

Re: Linking to static Net-SNMP libraries

[Gary Clark]

Are you attempting to build this on Linux? If so you need to have a complete
installation. Not partial when installing on linux.
You will get missing libraries if you only partially installing and yes
lcrypto is one of those missing libs. I also hit this problem.

Re: Using persistent file as config file

[Gary Clark]

Hello,

To append what Robert stated. Yes of course you can do this. Basically ( I
hate using that word but at this time
it seems appropriate) you will register a callback function which is
associated to a token. The token eg a unique string pattern
will exist in the persistence file i.e snmpd.conf  in
/var/net-snmp/snmpd.conf. You need to register a callback function.
An example of how to do this can be seen /agent/mibgroup/mibII/system_mib.c.

This was my starting point.
The function of interest is:

snmpd_register_config_handler(token,CallbackFunction,NULL,NULL);

This callback function is called when the agent identifies the presence of
the token. Of course the callback function is something you will create and
not something provided from mib template generation.

Cheers,
Garyc

Mib row deletion

[Gary Clark]

Hello,

A quick question on deleting mibs. I'm using mib2c to generate the c code.
All very dandy except I'm not on exactly how
to remove rows from the table. I thought I could use

CONTAINER_REMOVE(sig.container,row_ctx);

This does indeed remove the row from the mib table however I'm seeing an
error in the snmpd log:

error on subcontainer remove (-1)

Now I take it I'm doing something wrong. Whats the procedure for removing a
row_entry?

Much appreciated,
Garyc

Re: Cannot Process SNMP Traps

[Gary Clark]

Hello,

Only the first line of the snmptrapd.conf is relevant. Its the coldstart
trap. You need to remove the rest.
I'm too idle. The trap.pl is the script which trapd will call when it
receives the coldStart trap after
you initialised your agent correctly. The trap.pl will dump the trap
information to a text file correctly.

Thanks,
Garyc

trap.pl
Description: Perl program


snmptrapd.conf
Description: Binary data

Re: Cannot Process SNMP Traps

[Gary Clark]

Ok can you add the line:

trap2sink ipaddress comunityname
trapcommunity communityname

to your snmpd.conf file.


The ipaddress is the ip address of your local machine and community name is
the community name you specified
whilst building.

Much appreciated,
Garyc

Re: Cannot Process SNMP Traps

[Gary Clark]

Hi Russ,

Can you tell me what lines you exactly put into the snmpd.conf
and also exactly how you run snmptrapd. I'm guessing snmptrapd doesnt know
about snmpd.conf.

Also what the path on perl?

i.e which perl.

Thanks,
Garyc

Re: Cannot Process SNMP Traps

[Gary Clark]

Hi Russ,

Can you please run:

snmptrapd -c /home/snmptrapd.conf

with the configuration file I sent you. The perl script I also provided
should be in the same directory that you have the snmptrapd.conf.

Thanks,
Garyc

Re: Cannot Process SNMP Traps

[Gary Clark]

Hi,

snmptrapd -c /home/garyc/snmptrapd.conf

I sent the snmptrapd.conf I use for coldstart trap out yesterday and also a
perl script you can use
inconjunction with the snmptrapd.conf.

Have you tried doing that?

Thanks,
Garyc

Hi Russ,

Yeh it would be good to start with getting your basic coldstart trap to work
and then go from there.

Re: Cannot Process SNMP Traps

[Gary Clark]

Hi,

Ok three monthsGood one.

1) When running your agent have you configured your snmpd.conf to send
traps?
2) When running the snmptrapd it also has an associated configuration file
this
 should contain an oid value and a perl script which is called when the
trap is received.
3)  Examine the FAQ. This has more information.
4)  The most obvious trap to look for is the coldStart trap which is sent
when your agent
  has completed initialisation.
5)  If you get stuck I will help you more so dont panic ok.

Cheers,
Garyc

Deletion of rows from tables

[Gary Clark]

Hello,

I have recently spent some time looking at a problem I was seeing and am
asking anyone else if they
have seen this problem also.

Using RedHat 9.0 and net-snmp 5.1.2.

mib2c was used tocreate a template from the MIB.Everything was fine until I
wanted to delete an entry from the MIB.
I was seeing an error to delete a row from the container.
I examined the container.h and displayed what is inserted into the MIB and
what is removed. Within the container.h
there are two inline functions...ugh! one is called CONTAINER_REMOVE and one
is called CONTAINER_INSERT
.Within the insert function inserts the row of the table into a linked list
and then gets the next ptr of the table. This
is what is bothering me. Its inserting the value of the next container and
row into the list. I dont think this should be
doing this.
When I delete a row there are of course multiple containers within the list
when I only added one entry hence the failed
error message. The MIB row does get removed, but why is the next value of
the container also going into the list?

Any ideas?

Much appreciated,
Garyc

Re: Deletion of rows from tables

[Gary Clark]

Robert,

The point is that I was trying to understand where and how I can delete a
row from a MIB entry since there
is no documentation on this issue. I simply tried to trace how rows get
inserted and how they get removed.

Yes its a little fuzzy. The row index gets added to multiple containers when
I insert a row.

macro

Ahh thats the answer.Would really like to of known that.


Much appreciated,
Garyc

Net-SNMP 5.1.2 Memory leaks

[Gary Clark]

hello,

Has anybody seen the memory leaks with Red Hat 9 Net-SNMP 5.1.2?
I'm using the function CONTAINER_REMOVE to remove the context but its looks
like
it does not free memory? Eek? Has anybodyelse seen this? The context does
appear to be free from the list but no memory deallocation?

Thanks,
Garyc

Fw: Net-SNMP 5.1.2 Memory leaks on RH9

[Gary Clark]

Hello,

Ok I'm a little puzzled what I'm seeing:

I call CONTAINER_REMOVE (container,row);

This does indeed appear to remove the row. But the size of snmpd does not
reduce in size. After I have made the call the container does appear to be
purged of the row, but the memory size is still the same? Has anybody an
answer to this or seen this? its like row is marked as deleted but not
removed?

Thanks,
Garyc

[Gary Clark]

At the moment I cycle through all the rows in the container and call
CONTAINER_REMOVE. Is there a function I can use
to clear the contents of the container? I may be misusing this
CONTAINER_REMOVE although the entry does appear to get removed just not
freed from memory?

Thanks,
Garyc

Re: Net-SNMP 5.1.2 Memory leaks

[Gary Clark]

Robert thanks for the response. I'm using the RH9 "top" command and I should
see a drop in memory allocation when I call CONTAINER_REMOVE.
I dont, I definetly see it when a container row is created but not when I
call CONTAINER_REMOVE hence my concern.
When I perform a get operation it does look like its getting removed from
the container, but I dont see any memory size change which I should. The
reason I know that the row is still present is that I can still use the
pointer to the row object after CONTAINER_REMOVE. Hence the object still
exists.
Thats why I think its "marked" and not deallocated.

When I add new rows to the container the snmpd grows in size despite it
assuming previous deletion.

I'm trying to get purify to run on this beast but its crashing. Yet to
debug.

Cheers,
Garyc

Re: Net-SNMP 5.1.2 Memory leaks

[Gary Clark]

Ahh! I have just put the donkey outfit on and am now sitting in a corner
pretending I dont exist. Basically in my history with net-snmp project I
assumed better. Now much wiser, but still as stupid as a donkeys ass and
shining with pride I realized that I modified code in the table_array.c
which of course would not call the delete existing row. Now I have come to
my senses
and realize that I should chew on a carrot and lean towards sanity on this
issue. There is no leak.

Thank you.

Re: help please

[Gary Clark]

Hi,

What is this fusiv_linux? Do we have a net-snmp installation for this? I
know for sure that net-snmp-5.1.2 works for RH9 and is
fairly simple to install and build...or is my memory that blow.

Thanks,
Garyc

Can you run snmpd -D? This should dump the /var/snmpd.log. Have you modified
snmpd.conf?

Re: Threading and Net-SNMP

what I was told is that Net-SNMP is not thread safe. So be careful. Is this
a Red-Hat 9 system?

Ben Mate,

Try and read the FAQ its excellent to get started on this.

MIBS=all
MIBDIRS=/usr/local/share/snmp/mibs

Have a wee' browse at the file
/net-snmp-5.1.2/agent/mibgroup/examples/notification.c
it was useful to me.

Windows Net-SNMP

[Gary Clark]

Hello,

Quick question. I managed to use linux redhat 9 and NET-SNMP 5.1.2 and it
worked like a charm. Well the mantra was indeed long but eventually I got
it. They now want me to use Windows XP? Any advise on this would be helpful.
I thought I could download cygwin and just use windows like a unix platform
and use the provided version for cygwin for NET-SNMP?
Is that a good approach?

Cheers,
Garyc

Re: Windows Net-SNMP

[Gary Clark]

I will have to check it out. How do you add you own mibs in Windows when you
have the executable?
I thought you would have to recompile hence wouldnt I need the source code?

Cheers,
Garyc

Windows and Net-SNMP

[gary clark]

Hey,

I have a quick question regarding Net-SNMP on windows:

Just installed Net-SNMP 5.1.3.
Built snmpd and setup the snmpd.conf file.
Ran the command:
snmpd -a -d -Lf tempfile

I then perform the command:
  snmpget -v 2c -c public localhost sysUpTime

on the same machine:

When examining the tempfile, I can see that the agent
received the SNMP GET request:

Received SNMP packet(s) from UDP: [127.0.0.1]:1443
GET message
-- SNMPv2-MIB::sysUpTime

Sending 94 Bytes to UDP:[127.0.0.1]:162

Ok I get a timeout on the snmpget and dont see any
sysUpTime?

Any ideas?

Thanks,
Garyc

  -- SNMPv2-MIB::sysUpTime

[gary clark]

Much appreciated everyone. Changing the snmpd.conf
helped and also using sysUpTime.0 cracked it for me.

Thanks now for the real work on this.

Cheers,

Windows Perl on Net-SNMP?

[gary clark]

Hiya,

Been trying to build this windows Net-SNMP perl
version.
I downloaded ActivePerl which was fine for performing
get and set operations.

However I wanted to use the mib2c command to generate
the templates however this requires the Net-SNMP perl
installation.

Can somebody point to or offer some simple instruction
on how to build this blighter. I keep on hitting
problems whilst building and thought this has to be
simpler

Thanks,
Garyc

Building for windows Microsoft VC7 and VC8

[gary clark]

Hello,

I had problems with attempting to build and install
on Windows using 5.1.3 net-snmp package.

On one machine I built the package in its entirety
without failure using the intructions given in the
readme.win32 file. I never saw any problem except when
testing the perl module, some tests did fail, but not
all. I was able however to build the mib2c.

Ok on another development machine I attempted to use
Microsoft Visual Studio 8.
Using the readme.win32 I attempted to go through the
same instructions again.
The very first problem I encountered was the
vcvars32.bat is requested to be ran, but the build.pl
when executed will always fail due to requiring a
specific environment variable MSVCDir. This is not
being set in version 8.

Do later net-snmp packages handle changes in Microsoft
Visual Studio 8.


Thanks,
Garyc
