RE: snmpd under cygwin gdb.
Why does the error message, announcing the segmentation fault, look as if it comes from the DLL (kernel32.dll), and not from snmpd? Could it be that the segmentation fault owes its observation to a failure of MS programmers to handle a GPF? MS code is well know to be full of bugs, so perhaps the problem is not with gdb, or snmpd, or cygwin. I suppose I could be wrong but, on the face of it, the reported error suggests (to me) that the problem is with MS code. William R.

Re: how to best pass a usmUser to snmptrapd?
Actually, better yet we could make use of the fact that snmptrapd is a sub-agent already to the master agent. We could then simply register another usmUser table under a different SNMPv3 context (say snmptrapd) and thus you could configure snmptrapd's users by talking directly to the master agent. Slick! I'd install that into 5.2 hands down. Yup - that sounds good. You might even get beaten to installing it But it'd require more code, since the current usmUser code is written in the old API and doesn't handle contexts. Doesn't it? Couldn't we use register_mib_context rather than the macro REGISTER_MIB ? It probably hasn't had much practical testing, but it *ought* to work. (I would also draw the honourable member's attention to the FAQ entry: How can I register a MIB module in a different (SNMPv3) context? ) Which also raises a question about the notification log MIB. Would that perhaps be better registered under the same context? (thus freeing the default context version for a log of notifications sent by the agent) Dave --- This SF.Net email is sponsored by OSTG.

Getting data from table using net-snmp
Hi All, I am currently reading your tutorial on NetSNMP sub-agent development manual. The only change I made in my conf file is: com2sec local localhost democommunity master agentx Initially I start snmpd agent: ./snmpd -f -L -D and the the example-daemon you had provided : ./example-daemon Now I want to fetch the information from table at 1.3.6.1.4.1.8072.2.2.1. So i did snmpwalk -v 1 -c democommunity localhost 1.3.6.1.4.1.8072.2.2.1 to fetch the table in tutorial, I am getting nothing...not even error Am I missing something?. I just need to get all the information from the running sub-agent(table net netSnmpIETFWGTable) Thanks in Advance, PMM --- This SF.Net email is sponsored by OSTG.

Re: EngineID
Thanks Dave. This I will read. The reason why I asked this was because I am using the Single API functions equivalent to the Traditional API functions used in ucd-snmp-0.4.2.5 's snmpget application. Till now I was using only v2c(and everything worked fine), but now I wanted to get it running for v3 also. In my application the snmptrapd's code and snmpget/set's code work in parallel. Evevrything used to work fine till v2c. But when I start my application I get error as : Unknown token: engineBoots Unknown token: oldEngineId I am not able to understand why it gives this error message in the beginning. I am trying to dig out more. But if someone can pinpoint then it will be fast for me. Dave Shield wrote: How and where does snmpget application discover the engine ID of agent's machine? It uses the approach outlined in RFC 3414, section 4 Discovery. It actually sends the same request two or three times, in the sure and certain expectation that the first one(s) will fail. But the error reports that are returned from such failures will include the missing information (engineID and boot time/count) Try running snmpget -d or snmpget -Ddump to watch what goes on.

Re: mib2c.iterate.conf table implementation problem
I am trying to implement a table using net-snmp5.1. I
have a simple array that I want to rertieve from this
table. When I do a walk on this table it loops forever
in my get_next entry function.
The 'lnbCustom2Table_get_next_data_point' routine needs to return NULL
when it gets to the end of your table:
netsnmp_variable_list *
lnbCustom2Table_get_next_data_point(
void **my_loop_context,
void **my_data_context,
netsnmp_variable_list *put_index_data,
netsnmp_iterator_info *mydata)
{
int i = (int)*my_loop_context;
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point \n));
I'd be tempted for this debug statement to include the current index
value. I.e.
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point %d\n, i ));
netsnmp_variable_list *vptr;
vptr = put_index_data;
snmp_set_var_value(vptr,
(u_char *)custom2table[i].loBand,
sizeof(custom2table[i].loBand) );
How big is custom2table ?
What happens when you run off the end of it?
You probably need something like:
if ( i MAX_custom2table_INDEX )
return NULL;
(coming *before* the snmp_set_var_value statement above)
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point loBand\n));
*my_data_context = (void*)custom2table[i];
*my_loop_context = (void*)++i;
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point end\n));
I probably wouldn't bother with those two debug statements either.
A single debug output, containing all of the useful information about
this particular run is likely to prove clearer.
return put_index_data;
}

walking snmpd
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 --- This SF.Net email is sponsored by OSTG.

OpenNMS causes Net-SNMP to hang.
I'm running Net-SNMP 5.1.2-rc2 on a Red Hat 8.0 system. This server functions as a PPP Concentrator and thus has anywhere from 400-500 PPP interfaces up at any given time in addition to two Ethernet interfaces. I am using OpenNMS 1.1.2 to monitor this server and others like it. When OpenNMS runs its SNMP discovery process it appears to query for all the interfaces on the Concentrator system. Shortly after the query begins, Net-SNMP hangs and is non-responsive until the daemon is killed and restarted. From observing the output with tcpdump, I see that some responses get back initially, but eventually cease altogether. I started snmpd with the -D -f -Le options to see if I could figure out what was going on. Far too much meaningless debug output for my eyes, but data was certainly scrolling by at a rapid rate even while the SNMP server appeared to be hung as far as outside programs were concerned. What scrolls by mostly is the following: trace: handle_getnext_loop(): snmp_agent.c, 2644: results:trace: sprint_realloc_by_type(): mib.c, 1971: output: sprint_by_type, type 5 . = NULL Literally hundreds of times at a very high rate. Occasionally a large chunk of PPP PPP PPP and so forth scrolls by and then the previous block continues looping in its place. I've brought this to the attention of the OpenNMS people, but many of them tell me they are monitoring boxes with that number of interfaces with no problems and suggesteted I check here for any suggestions. A normal snmpwalk doesn't appear to freeze up Net-SNMP. I should mention that I have tried both SNMPv1 and SNMPv2c queries from OpenNMS to see if the issue was exclusive to one version or the other. No difference however. Hope someone can give me some ideas! Ray Van Dolson --- This SF.Net email is sponsored by OSTG.

RE: mib2c.iterate.conf table implementation problem
That was it. I had to return NULL once I reached the max no of entries. It is working
now.
Thanks a lot for your prompt reply.

Subject: Re: mib2c.iterate.conf table implementation problem
I am trying to implement a table using net-snmp5.1. I
have a simple array that I want to rertieve from this
table. When I do a walk on this table it loops forever
in my get_next entry function.
The 'lnbCustom2Table_get_next_data_point' routine needs to return NULL
when it gets to the end of your table:
netsnmp_variable_list *
lnbCustom2Table_get_next_data_point(
void **my_loop_context,
void **my_data_context,
netsnmp_variable_list *put_index_data,
netsnmp_iterator_info *mydata)
{
int i = (int)*my_loop_context;
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point \n));
I'd be tempted for this debug statement to include the current index
value. I.e.
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point %d\n, i ));
netsnmp_variable_list *vptr;
vptr = put_index_data;
snmp_set_var_value(vptr,
(u_char *)custom2table[i].loBand,
sizeof(custom2table[i].loBand) );
How big is custom2table ?
What happens when you run off the end of it?
You probably need something like:
if ( i MAX_custom2table_INDEX )
return NULL;
(coming *before* the snmp_set_var_value statement above)
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point loBand\n));
*my_data_context = (void*)custom2table[i];
*my_loop_context = (void*)++i;
DEBUGMSGTL((lnbCustom2Table,
lnbCustom2Table_get_next_data_point end\n));
I probably wouldn't bother with those two debug statements either.
A single debug output, containing all of the useful information about
this particular run is likely to prove clearer.
return put_index_data;
}
Dave

Re: Proxy Question

This is not possible in the currently released Net-SNMP packages. hoil Originally, SNMPv3 supports Proxy Agent using ContextName. hoil Instead, I wish to using Community Name in SNMPv2. hoil When this function will be supported? I just implemented it for what will be Net-SNMP 5.2. Please check out the CVS sources if you want to play with it now. The com2sec tokens now support a -Cn flag which maps a community string to a SNMPv3 context, and thus you can use the same context in the proxy -Cn flag and it should do what you want. -- Wes Hardaker Sparta --- This SF.Net email is sponsored by OSTG.

Trap Implementation Idea????
Hi I have just gone through the trap tutorial and the notification example for trap. I could get trap successfully from snmpd. Now I need to design some traps that would be triggered when an event has occurred somewhere outside the agent. To be more specific, my agent is running on a Linux box. I have PCI card on that box that runs a task from a processor. Within the scope of this task I need a trap to be generated once certain event has occurred. Previously we used SNMP research agent with our windows platform. We used to directly call DoV2cTrapToDest() or kind of trap2send from our code with the help of an agent library. What could be the possibility for net-snmp to communicate with the other task and generate an event instantly? Thanks, Sabina __ Do you Yahoo!? Yahoo!

Re: how to best pass a usmUser to snmptrapd?
On Fri, 30 Jul 2004 07:17:44 -0700, Wes Hardaker [EMAIL PROTECTED] said: Dave Couldn't we use register_mib_context rather than the macro Dave REGISTER_MIB ? It probably hasn't had much practical testing, Dave but it *ought* to work. Wes Don't know. I haven't looked at it enough... Well, I looked at it. A lot. In short, I did it. The notification log tables are now registered under the snmptrapd context, as is the snmptrapd usmUser table. Thomas, given the current main line cvs code you should be able to manage smnpv3 users under the snmptrapd application by default now. I thought it was going to be a quick task, and thus explaining how to do it would take longer than doing it so I started in on it. However, in the process I found that I'm not sure agentx has ever supported contexts properly so I had to fix that first. Additionally, I think I solved another issue with contexts that was previously causing incorrect errors to be returned for !default contexts. There is one bug left to fix, which is that the first thing registered under a new context is missing. -- Wes Hardaker Sparta --- This SF.Net email is sponsored by OSTG.
