This is the mechanism to discover the engineID of a unknown device. The manager should continue and request the information using the discovererd engineID. If you have duplicate engineIDs the manager will stop or send out the request with a wrote bootCount.

The snmp packages on this particular system may be very old, but they are the newest I can find on Red Hat Network for RHEL4. We will be upgrading to RHEL5 soon. FWIW, RHEL5u1 ships with net-snmp-5.3.1-19.el5.i386.rpm u2 is out, but I don't have an image of that disc. CentOS 5.2 ships with net-snmp-5.3.1-24.el5.i386.rpm You're never going to get the latest stable release with Red Hat or CentOS. They're enterprise-class OSes, where stability and predictability are far more important than having the latest code. If you wanted to keep this stuff more up-to-date, you could try Fedora, but you're also much more likely to be chasing weird bugs and inconsistencies.

I apologize for my ignorance of community support list usage. I am an old IBMer and not familiar with the proper open source community behavior. It's all good. The general principole is to keep list related discussions as list discussions. This keeps the information available in the archives for folk to find later, and also keeps an enviroment where everyone is welcome to jump into the discussion, which is generally a good thing. You should only call p;eople out by name when asking a question to them directly, as I will do now to you. Also, I notice as I read the postings on the list that my posting is the only one that does not have a Topic heading. Please let me know how I can establish a Topic for my posting. I'm not sure. Are you talking about a web interface to the archives here? Thank you for your help and patience. Here is the information you requested.

I had read in the Net-SNMP docs Hmmm - the kernel isn't the most recent, but should be good. The package is darn old, though - we're on 5.4.2 now, and the revs don't come quickly - I'd estimate you have a 4 or 5 year old package. But even that shouldn't have this problem. You may want to do a `yum upgrade -y` on that system, if you are comfortable doing so. If someone on the list could point us to thye most recent RPMs, please? Once you have upgraded or not, as befits, please post the following: 1) The snmpd log (tip: use the -Le flag and cut and paste from the console, or use `-Le 21 | tee snmpd.log` to save it to a file while keeping it on the console. 2) The command and response for a successful get or getnext. 3) The command and response for a failing get or getnext. 4) The text of snmpd.conf I need a lot of info because I have no idea why this may happen.
