seg. fault on calling send_v2Trap
I am using ucd-snmp-4.2.5.
I have everything running in the agent i.e. snmpget, snmpset etc. But as
shown in example.c, if I trigger send_v2Trap() through a snmpset call
then the agent gives segmentation fault. i.e. I make a snmpset on a
particular column and within its write function I call send_v2Trap with
necessary parameters. And it gives seg. fault. If I don't call
send_v2Trap then it works fine.
I tried sending traps by another way i.e. creating a separate thread at
the start of agent after
init_agent("snmpd");/* do what we need to do first. */
init_mib_modules();
/* start library */
init_snmp("snmpd");
createThread(); // here I create a separate thread which calls a
separate function which further use send_v2Trap to send traps at an
interval of 10 secs.
This way it works fine and I can do snmpget/set also in parallel. But I
don't understand why it fails if I do it like as it is explained in
example.c. Does it clash somewhere?
Thanks

Re: magic numbers
My question is answered from the first part which you have explained. I
am using v4 API (ucd-snmp-4.2.5). I already tried to do the same i.e.
{ 1, .,, var_this, . },
{ 2, .,, var_this, . },
{ 1, .,, var_that, . }
it didn't give any problem but still wanted to be sure.
Thanks for your reply.

magic numbers
I have used mib2c to create the skeleton code for 3 tables which are in same MIB file. But in the variables structure, the magic numbers(for all 3 tables) are generated in increasing order starting from 4 one after another. 1) Why does the magic numbers start from 4? 2) Will there be any problem if I change the value of magic numbers and start them from 1 for each respective table in the same array structure? which means the value of these magic numbers will not be unique in the same structure but they will be unique for their respective tables and their sub-identifiers will also be unique.

coldStart, warmStart, linkUp, linkDown Traps
Hi all, * I am using ucd-snmp-4.2.5. When I start the agent I get coldStart trap with following variables: 12:58 TRAP0.0 from 0.0.0.0 Trap-Type: Cold Start Variables: system.sysUpTime.0 = Timeticks: (5) 0:00:00.05 .iso.org.dod.internet.snmpV2.snmpModules.snmpMIB.snmpMIBObjects.snmpTrap.snmpTrapOID.0 = OID: .iso.org.dod.internet.snmpV2.snmpModules.snmpMIB.snmpMIBObjects.snmpTraps.coldStart.iso.org.dod.internet.snmpV2.snmpModules.snmpMIB.snmpMIBObjects.snmpTrap.snmpTrapEnterprise.0 = OID: enterprises.ucdavis.ucdSnmpAgent.linux But when I stop my agent then still I get coldStart trap with less number of variables 12:58 TRAP0.0 from 0.0.0.0 Trap-Type: Cold Start Variables: system.sysUpTime.0 = Timeticks: (1407) 0:00:14.07 .iso.org.dod.internet.snmpV2.snmpModules.snmpMIB.snmpMIBObjects.snmpTrap.snmpTrapOID.0 = OID: enterprises.ucdavis.ucdTraps.0.2 and the value as "ucdShutdown"Why don't I see the value "ucdStart" in the 1st trap when I start agent? * When do we get warmStart, linkDown and linkUp traps? * I want to generate linkDown and linkUp traps at some specific time(after getting some interrupt from my Hardware).

Re: implement snmpv3
The Net-SNMP toolkit find it automatically but once I tried to use some 3rd party SNMP manager. In order to configure it so that it could query/set the values from agent, it asked me to provide the EngineID of my UCD-SNMP agent. But I did not know where does agent store the value of its EngineID. Is it in /var/uc-snmp/snmpd.conf file? If yes, then what is the name of token? For receiving traps in this 3rd party manager also, I had to give the engine ID of Agent. Has this to be given as a param in 'trapsess' derivative in snmpd.conf file? OR some other way is also there?

Re: EngineID
But when I start and stop snmptrapd application to receive v3 traps from my agent, I see a file /var/ucd-snmp/snmptrapd.conf being created with engineBoots and oldEngineID tokens in it and "createUser" replaced by "usmUser". And I see engineBoots value getting incremented by 1 whnever I start/stop snmptrapd app. So it means this file is being generated by the Trap receiver app. and these tokens are also used by it. What is the meaning of oldEngineID? and what kind of value is stored in it? In which file does the Request Generator application e.g. snmpget will store the engineID/Boots information(that will come from Agent being queried)?

Re: EngineID
I don't create these tokens myself. I only write "createUser"(with necessary parameters) in /var/ucd-snmp/snmptrapd.conf (for ucd-snmp-0.4.2.5). After this once I start and then stop my application, I see "createUser" replaced by three tokens: usmUser engineBoots oldEngineID And then after restarting my application it complains about the last two tokens. I have tried the same by preparing a new application program, using the code of snmpget/set, snmptrapd and using threads so that I can achieve the functionality of both in parallel. Everything works fine here. So now I am convinced that something is not in order in my previous application. Thats what I am curious to find out so that I don't make that mistake again.

Re: EngineID
Ya, I am also trying to find out the same i.e. why my app. doesn't pick
up these tokens automatically. May be - while mixing up the code of
snmpget and snmptrapd I have eaten up something(I did this 2 years back)
or I have called the initialization routines in different order or this
is happening because of some of the Traditional API functions(which I
also don't think so) which I have used instead of Single API (as
mentioned in README.threads).

Re: EngineID
I didn't get your point completely. Why should I call init_agent() from
my management application i.e. the code which will either receive traps
or make snmpget/set commands only. Also, I didn't find init_agent being
called from the code of tools snmptrapd.c and snmpget.c I saw the
following routines being called from snmptrapd.c
/* register our configuration handlers now so -H properly displays
them */
register_config_handler("snmptrapd", "createUser",
usm_parse_create_usmUser, NULL,
"username (MD5|SHA) passphrase [DES
passphrase]");
register_config_handler("snmptrapd", "usmUser",
usm_parse_config_usmUser, NULL, NULL);
/* we need to be called back later */
snmp_register_callback(SNMP_CALLBACK_LIBRARY,
SNMP_CALLBACK_STORE_DATA,
usm_store_users, NULL);
/* Initialize the world. Create initial user */
init_snmp("snmptrapd");
which I am also calling from my application. Still I don't understand
why I get these "Unknown token" errors.
Note: I am not calling the following(as in snmptrapd.conf file I mention
only "createUser"). Can this cause some problems?
register_config_handler("snmptrapd", "traphandle",
snmptrapd_traphandle, NULL,
"oid|\"default\" program [args ...] ");
register_config_handler("snmptrapd", "format1",
parse_trap1_fmt, free_trap1_fmt,
"format");
register_config_handler("snmptrapd", "format2",
parse_trap2_fmt, free_trap2_fmt,
"format");

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.

EngineID
Hi, How and where does snmpget application discover the engine ID of agent's machine?

Re: Snmp Agent as a thread
I have tried my application's code as a separate thread from within the ucd-snmp agent's code. It works fine. And within my application's code I am further creating multiple threads using mutex etc. This way everything works.

Re: few more questions related to SNMPv3
Thanks Dave. I have one more question - If I try to access UCD-SNMP-4.2.5 agent v3 with any other 3rd party SNMP Manager then it is required to mention the EngineId of agent into the configuration files of some of these SNMP Managers. Where do I find the value of EngineId of agent? Please note that I don't write the createUser line in /var/ucd-snmp/snmpd.conf file. I write it in the same snmpd.conf file where the access control stuff is mentioned.

How? > What was the exact command used? > Where exactly is the (SNMPCONFPATH) file? Yes. I restarted the agent as --non-root-- user like: ./snmpd -c Config_agent.txt -p 9000 -f and the SNMPCONFPATH I set to same folder where my agent's executable and snmpd.conf are Note: Config_agent.txt is a separate config file which I need for my own purpose. Within snmpd.c file, I parse this config file accordingly. And for snmpd.conf file agent read the path from SNMPCONFPATH env variable. With these settings I have been working since few months. Agent read both snmpd.conf and Config_agent.txt files separately and behaves accordingly and works absolutely fine. And I hope that for the SNMPv3 also reading of snmpd.conf this way should not affect any thing else. But what I observed was that if I run agent as --non-root-- user then it is not able to access the /var/ucd-snmp/snmpd.conf file. I think that's why it is not able to know about the 'createUser' also. But I am restricted at this point that I cannot run my agent as root and also doesn't want to use ports 161 and 162. > > It's probably worth stopping the agent, and running it with > > snmpd -f -L -Dread_config . > > so you can watch it as it reads in the config files. > No. agent works fine.

few more questions related to SNMPv3
1) I create the following entries: ---in /var/ucd-snmp/snmpd.conf createUser userSoni MD5 lightlight DES ---in snmpd.conf(where SNMPCONFPATH is set) rouser userSoni This is how its mentioned in README.snmpv3 file and then I do snmpget -v 3 -l noAuthNoPriv -u userSoni 192.168.1.189:9000 ..OID.. But i get the message snmpget: Unknown user name 2) What can be the wrong? Also, I have seen that /var/ucd-snmp/snmpd.conf file gets read and updated by agent only if it is running as root. But I don't want to run my agent as root(as I don't use the defalut ports 161 and 162 for communication) and for some other reasons also. Same problem I face on the other side with 'snmptrapd' accessing /var/ucd-snmp/snmptrapd.conf file for the user entries. Can anybody suggest an alternative to this?? How can I make agent and trap daemon access the respective files without running as root. 3) In README.snmpv3 file, the entries related to com2sec, group, view and access derivatives are not explained. Are these entries not mandatory to be specified in snmpd.conf for using SNMPv3 ?? OR the combination of 'rouser/rwuser' and 'createUser' is sufficient(at least for the first step) for configuring agent for SNMPv3??

Re: problem in configuring agent for SNMPv3 protocol
Yes, you are right. SNMPv2 traps I could receive with HP Openview but not SNMPv3 traps. The reason was same as stated by you..I found that the HP Openview's version which I was using for testing doesnot support SNMPv3. Thanks Dave. Dave Shield wrote: > > > One more question.

Re: problem in understanding role of engineID for SNMPv3 protocol
Hi Dave and others, Few more doubts..
I read the following about SNMPv3:
---The user database in a SNMPv3 application is referenced by a
combination of the user's name("security name") and an identifier
for the given SNMP application you are talking to("engineID").---
My question:
Let's say A(SNMP Agent) and B(SNMP Manager) are my two applications. So
if I have to make a get request from B->A, then on B's user database
three things will be stored i.e. "user name" and "password"(provided as
param to snmpget) and "engineID of A"(as mentioned in above statement).
* How does B fetches the engineID of A and what it is composed of?
* Will the same procedure be followed if I use any other SNMP Manager
application(other than ucd-snnmp's 'snmpget' app.)
and I read this also:
---The SNMPv3 TRAPs use the engineID of the 'local' application(sending
the traps) rather than the engineID of the 'remote' application---
My question:
If I send traps from A->B, lets say using 'snmptrap' application like:
snmptrap -v 3 -u myuser -a MD5 -A mypass -l authNoPriv B's_address 42
coldStart.0
Now, where does the engineID play a role here and how does the trap
receiver compare this engineID send by A?
Any help would clear my doubts.
Thanks
Soni

Re: problem in configuring agent for SNMPv3 protocol
Hi Dave, One more question. What does this *all* list of parameters include for 'trapsess' derivative? I have include security level and username. Here are my settings in snmpd.conf file for v3: createUser public MD5 my_password DES com2sec public192.168.1.210 public group publicv2c public group publicusm public view all included .1 #accesspublic"" any authexact all none none accesspublic"" any noAuthNoPrivexact all none none trapsess -v 3 -l noAuthNoPriv -u public 192.168.1.210:9001 public ### With these settings, I can receive the traps using apps/snmptrapd, but when I try to receive the traps in any other 3rd party SNMP Manager e.g. HP Openview etc. then it doesn't receive. * Am I providing all necessary parameters in snmpd.conf with respect to configuring agent for SNMPv3 protocol? * Or Is there something to be configured on the Manager side for SNMPv3? * Or can there be a problem in my MIB file also which these Managers use?

Re: What if Mgr. dies!!
In addition to this, you can create a cron job in the backgroud which will check for your manager regulary(at some particular interval of time) and in case it finds the manager dead then with help of this cron job you can start it very next moment. And with the next start you can check for those missed(logged) traps also. I would also like to know about any other better option.

Re: problem in configuring agent for SNMPv3 protocol
when I give the version as -- trapsess -v 2c localhost:9001 then the snmptrapd receive all the traps, but with -v 3 it doesn't receive anythingnot even the Cold Start trap from agent. How can I make apps/snmptrapd receive traps with the following statement in snmpd.conf file of agent? trapsess -v 3 localhost:9001 Do I have to set anything else somewhere OR Do I have to provide 'version number' command line parameter while running snmptrapd??

problem in configuring agent for SNMPv3 protocol
Hi all, I am using UCD-SNMP-0.4.2.5 Everything used to work with SNMPv2 -snmpget, snmpset and traps also. Now I want to configure the same agentfor SNMPv3 protocol. I just changed the snmpd.conf file in the followingway(replacing the previous entries for SNMPv2): ## ## for get/set requestscreateUser public MD5 my_password DES com2sec public 192.168.1.210 publicgroup public v2c publicgroup public usm publicview all included .1access public "" any noauth exact all none nonea ## for traps #trapcommunity public # trapsink: A SNMPv1 trap receiver# arguments: host [community] [portnum]#trapsink localhost:9001#trapsink 192.168.1.210:9001 # trap2sink: A SNMPv2c trap receiver# arguments: host [community] [portnum]#trap2sink localhost:9001#trap2sink 192.168.1.210:9001 trapsess 192.168.1.210:9001 public#trapsess 192.168.1.210:162 public ## With the above changes in snmpd.conf The snmpset and snmpget works. Butthe traps are not working properly. After running./snmptrapd -P -p 9001 -F "%02.2h:%02.2j TRAP%w.%q from %A\n Trap-Type:%W\n"I only get two traps: 1st "Cold Start" when agent is started and 2ndwhen agent is stopped. I am not able to receive other traps. I was using send_v2trap() in my mib.c with SNMPv2 when everything usedto work. Do I have to change this for SNMPv3(Documentation doesn't sayso)? OR anything else anywhere? OR if anyone can point out what I amdoing wrong. Any comments please. RegardsSoni Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers!
