sizeof long

2005-02-15 Thread Roger Nilsson 








Hi,

 

When I compile and run my application sizeof(long) returns
8.

Does net-snmp define long to 8?

If it does, why and where?

This only happens when I use the net-snmp libs in my
application, otherwise sizeof(long) returns 4.

 

net-snmp verison: 5.0.9

OS: solaris9

Compiler: CC (64bit application)

How to configure access control info in snmpd.conf file

2005-02-15 Thread Chenna 
HI all,

   Im using Net-SNMP 5.1.2. While starting the agent using
"/usr/local/sbin/snmpd -Lf log.txt" it is writing the following error
message in the log file.

---
log.txt

Warnging : No access control information configured.
   It's unlike the agent can serve any useful purpose in this state,
   Run "snmpconfig -g basic_setup" for help u configure the snmpd.conf
file for the agent .
NET-SNMP version 5.1.2.

I have used the above command also. But im not able to runt the daemon
successfully. Ind also the agent not recognized by the loriotproV3
manager.

Please help me..

Thanks in advance

We get the stats from the kernel. I know for linux, vlans do not track
bandwidth, and do not appear in the interfaces table. Not sure for FreeBSD...
 

Using 4.10-release. It used to work... it's just randomly stopped.

Re: How to configure access control info in snmpd.conf file

2005-02-15 Thread Sridhar S 
Chenna,

After you run "snmpconfig -g basic_setup" command look for the file
"snmpd.conf" in the local directory. Copy it to /tmp (for example) and
restart your 'snmpd' as '/usr/local/sbin/snmpd -C -c /tmp/snmpd.conf -f'
(-f for foreground running). 

Go through the man page of snmpconf for more information.

Robert, I know you're the expert here but I've got non-standard Interfaces 
working without patching code.  I disabled interfaces in the agent (-I 
-interfaces) and then have a sub-agent which implements interfaces (I ran mib2c 
on the interfaces MIB and filled in the code).  I'd _love_ to be able to have 
both and another active thread on this list (Managing multiple instances of a 
MIB) suggests I can.  But you can, at least, implement interfaces without 
patching anything.  Or maybe I misunderstand the OP's intent.

My code says:

session.peername = "localhost";
session.retries = 1;
session.version = SNMP_VERSION_2c;
session.community = "config";
session.community_len = strlen(session.community);

/* establish the session */
ss = snmp_open(&session);

snmp_log(LOG_INFO, "peername:%s\n", session.peername);
snmp_log(LOG_INFO, "community:%s\n", session.community);

and the log output is:

   peername:localhost
   community:(null)

What the heck is _that_ about?

problems with mib2c

2005-02-15 Thread manik chopra 
Hi all,

I have problems using mib2c functionality of NET-SNMP.

I have got a directory in which
"NET-SNMP-TUTORIAL-MIB" is saved. Also it is in the
default search path for the MIBS. Now when I do 

>>mib2c mib2c.int_watch.conf nstAgentModuleObject

following error occurs:
---
you didn't give me a valid OID to start with at
/usr/local/bin/mib2c line 115


I tried to look around but could'nt figure out the
reason. Earlier when I compiled and the installed the
"perl/" package for NET-SNMP: 

"./configure & make" went fine but when I did "make
test" following error occured:

-

can anyone please help me in how to get the mib2c

Excellent question. I don't see anything in the code that would clear the
memory in the input session. Is ss NULL? If not, what does it contain for
community?

Whenever something really weird like this happens, my first thought is
'mismatched libraries.' Check that

ls /usr/lib/*snmp* /usr/local/lib/*snmp*

doesn't return multiple versions of the libraries. I'd also recommend building
a static version (configure --disable-shared --enable-static) for easier
debugging, and stepping into snmp_open and following it down the stack,
watching to see where the community gets cleared.

Try running the agent in the foreground with debug:

snmpd -f -Le -DmibII/interfaces

Then walk a column (maybe ifType) and send us the debug output.

I'll look.

Yeah, we've had that discussion before.  I was pretty careful to scrub by 
development and test systems for 5.1 libraries before I did this.  I did `make 
-n` and looked at all the directories listed for -L options.  I've done 
ldconfig.

Nothing in /usr/local/lib, all 5.2.1 in /usr/lib.

Does 'snmptranslate -IR nstAgentModuleObject' work?

Also, I'd recomment trying a more recent release - 5.2.1 if possible, or 5.1.2
if you want to avoid the bleeding edge.

The simplest fix is

echo "rocommunity public" > /usr/local/share/snmp/snmpd.conf

That allows anyone to query the agent. Configuring more restrictive access
control is strongly recommended, and is covered on the web site in the FAQ and
the tutorial.

No, and application cannot change the size of a base C type.

I find that difficult to believe. The size of a long is determined by the
compiler.

RN> Compiler: CC (64bit application)

If you are using a 64bit compiler, you are going to get 8 byte longs. Perhaps
your other applications are using a different compiler, or different compiler
settings (like a 32bit compatibility mode).

Summarizing from my FAQ here:

http://www.freesnmp.com/net-snmp/faqs/#multidev

You can have both by using contexts, but:

1) snmpwalk or snmpget can only deal with one at a time.
2) the user has to know to use the non-default context
3) allowing v1/v2c access to context requires some setup shennanigans.

Having said that, there is another way to have both, but it does have some
risks. See my next response to Jeff in this same thread.

I guess we have a problem of definition then.  I'm not "patching" unless I have 
to keep track of my changes and update distributed source with `patch`.  (And 
my -I is done at runtime, not build time).

OK.  I've built with static libraries and my code now looks like:

session.peername = "localhost";
session.retries = 1;
session.version = SNMP_VERSION_2c;
session.community = "config";
session.community_len = strlen(session.community);

/* establish the session */
ss = snmp_open(&session);

snmp_log(LOG_INFO, "session.peername:%s\n", session.peername);
snmp_log(LOG_INFO, "session.community:%s\n", session.community);


if ( ! ss) {
snmp_perror("ack");
snmp_log(LOG_ERR, "Could not establish session with SNMP daemon.\n");
return NULL;
}

snmp_log(LOG_INFO, "ss:%p\n", ss);
snmp_log(LOG_INFO, "ss->peername:%s\n", ss->peername);
snmp_log(LOG_INFO, "ss->community:%s\n", ss->community);

and my log says:

  session.peername:localhost
  session.community:(null)
  ss:0x101689e0
  ss->peername:localhost
  ss->community:(null)

I can't really step into the code because the target environment is an embedded 
system where I don't have good debugging support.  I can pepper snmp_open() 
with fprintf()s. :-/  But you say that you don't see anything there that would 
trash the community...

Ok, since the two of your seem gung-ho on mixing in extra interfaces, here's
the scoop.

The problem with mixing interfaces is the ifIndex. By definition, the index to
a table for a particular row must remain constant for the lifetime of the agent
process. [Note that this is not true for the existing mibII/interfaces.c
implementation for some platforms. Bringing interfaces up and down can re-order
the table, which is bad new for someone trying to monitor a particular
interface.]

So the trend is to try and use the ifIndex from the kernel, wherever possible.
The new IF-MIB implementation (in if-mib/*) does this. So, if you want to mix
in proprietary interfaces that the kernel doesn't know about, how do we ensure
that the ifIndex values don't clash? The easiest way is probably to define an
offset for ifIndexes for the proprietary interface types. For an embedded
system, this is probably pretty easy, as the interfaces will likely remain
constant. But it isn't too hard to imagine a scenario where a conflict could
occur. So, if you've evaluated the risk and found it acceptable, select an
offset you are comfortable with.

Now, how to integrate with the existing code? I recommend using the new IF-MIB
implementation, because I think that is the direction that the code base is
moving. The old implementation will probably be phased out (off by default)
over the next few releases. If you platform is Linux, then the bulk of the work
is already done. [If it is some other platform, then the old style code needs
to be ported to the new style.] You will have to patch the agent, but it should
be a one line patch to call your code to add the additional interfaces.

There are two places where you could put the call. The key function is
netsnmp_arch_interface_container_load(). This function is called from
netsnmp_access_interface_container_load() in
if-mib/data_access/interface_common.c. It's purpose is to populate a container
with interface entries. The Linux implementation is in
if-mib/data_access/interface_linux.c, which should serve as your example of how
to create and add entries. You can add a call to your function before, after or
inside the *_arch_* call.

You will need to configure with --enable-mfd-rewrites (recommended) or
explicitly exclude the mibII/interfaces module and include the if-mib modules.

Ok, if it isn't mis-matched libraries, then my next guess will be mis-matched
headers. See if this finds multiple copies:

find /usr/include /usr/local/include -name snmp_api.h -print

A dup in ucd-snmp/snmp_api.h is ok, but if it finds more then that's likely the
problem, since the session structure size changed between releases.

You may have hit on it!  I've got a cross-build environment where the headers 
used to build my clients are in a kind of weird place and I can easily imagine 
that those copies didn't get updated when I tried to use 5.2.1.

Is there any version information in the header?  I guess I can diff the files 
on my include path against those in the NetSNMP 5.2.1 distribution... off to 
check.

AgentXSocket address

2005-02-15 Thread Emi . Yanagi 

Hi,

I enabled master agentx in smnpd.conf, and added AgentXSocket address to my tmplocal:
  master  agentx
  AgentXSocket tmplocal/var/agentx/master

My snmpd is running okay with the above setup, but the example-demon I compiled from the tutorial got the following error:

Error: Failed to connect to the agentx master agent: Unknown host (No such file or directory)

My question is, if I set AgentXSocket address to non-default, how do I pass the information to example-demon?

Thanks for your helps.

RE: Non-standard interfaces in ifTable

2005-02-15 Thread Jeff Olhoeft 
Thank you, this is exactly what I was looking for. I agree
that getting the kernel to report the interfaces correctly
is the ideal approach. That will be my prefered approach,
but not being familiar with that part of the system, I like
having alternative approaches. Another issue is that some
ifTypes are not being identified correctly. I have identifed
the part of the code (the MFD version) where that is an issue
and hope to put together a patch in the next week or so.

Thanks,

Jeff

Re: problems with mib2c

2005-02-15 Thread manik chopra 
Hello Robert,

Yes 'snmptranslate -IR nstAgentModuleObject' does
work.
But still i get the same error with mib2c. 

Also, initially I was using net-snmp-5.2.1. But
whenever I ran mib2c following error occured:

--
ERROR: You don't have the SNMP perl module installed. 
Please obtain
this by getting the latest source release of the
net-snmp toolkit from
http://www.net-snmp.org/download/ .  Once you download
the source and
unpack it, the perl module is contained in the
perl/SNMP directory.
See the README file there for instructions


I installed the perl module but still i get the above
error when I run mib2c.
