Re: Help, please. Can't get privacy to work
Ethereal reports that the reply to my encrypted PDU requesting sysLocation is a value of 3 for SNMP-USER-BASED-SM-MIB::usmStatsDecryptionErrors.0. That would tend to indicate that it's the *agent* that can't decode the incoming request properly. I infer that something about snmpd on my target isn't handling DES decryption. . I know I read somewhere that I have to have to build snmpd with SSL to get encryption. Yes - that's right. The suite relies on the OpenSSL libraries (or equivalents) to implement the various encryption algorithms. Nothing actually uses Secure Socket Layers as such - it's the encryption routines themselves that we don't provide. How can I prove that snmpd has SSL build in? U... a) Try snmpget UCD-SNMP-MIB::versionConfigureOptions.0 That won't say explicitly, but will indicate how the suite was configured (which may indicate if it either turned on or turned off use of OpenSSL). b) ldd snmpd That will show you which libraries are being linked to - any mention of 'libcrypto' or something similar would tend to indicate that it should support encrption c) nm snmpd | grep -i encrypt This should list 'sc_encrypt' regardless, but anything else is a Good Sign. d) strings snmpd| grep -i encrypt strings libnetsnmp.a | grep -i encrypt If either of these include the message Encryption support not enabled (or similar) then you're out of luck. (or at least would need to reconfigure/recompile) Though in fact, the remote agent should probably be logging this anyway. It might also be worth running the remote agent with '-Dscapi' and seeing what the debug output says. A few things for you to try, anyway.

Jim,
I had the same issue but it was because of a bug in SNMP. If there is no ip address on the interface, then it crashes. My OS is solaris.

Subject: snmpd crashed by snmpwalk
Hi Greeting:
I encountered one snmpd crashed due to the snmpwalk timeout at the IF-MIB::ifNumber.0 . All the values before IF-MIB were returned. But there is time out on IF-MIB.
I ran the snmpwalk to another host. It went through okay. The two systems have different OS level of Linux. The snmpd was developed and build on Linux 2.4.18 and then was
installed on Linux 2.4.21-mtd.1 All the snmpwalk on Linux 2.4.18 got returned values and didn't crash the snmpd.
The system which was crashed by snmpwalk has OS Linux 2.4.21-mtd.1.
I have couple questions. If the OS level difference is critical then why the MIB values before IF-MIB are returned
fine? It should not return anything from the beginning, right? Could it be some specific device interface hard to be recognized on the target machine which causing the crash?
However the man page of snmpwalk said -
If no OID argument is present, snmpwalk will search MIB-2. If the network entity has an error processing the
request packet, an error packet will be returned and a message will be shown, helping to pinpoint why the
request was malformed.
If the tree search causes attempts to search beyond the end of the MIB, the message End of MIB will be displayed.
This is how I ran snmpwalk - without giving a OID or name.
So if there is some unrecognized device IF on the target system most likely an error message is displayed. Shouldn't caused the crash, right?
Any pointing to the direction of searching the cause is highly appreciated. Thanks in advance.

That is your problem. WNOHANG means don't wait for a child that hasn't exited
yet, and will return immediately if the child is still running. And specifying
a parameter of -1 will wait for any child, not necessarily the one you just
ran. Either take out WNOHANG to actually wait for the child to complete, or
periodically call waitpid as you do above to reap defunct processes.

RE: waitpid for child processes invoked from agent
Hi Robert:
Thanks a lot for your kind reply.
It makes sense to me now. Just one more question to fully clarify this matter. From
the description from man page. I have feeling that I have to set the value of pid to
0 - which means to wait for any child process whose process group ID is equal to
that of the calling process. Meaning my program only wait for the specific child
processes forked by the parent process. Of course I should take out the WNOHANG.
What it happened here is the typical problem while some one inherit code from some
existing source and without fully understanding what exactly the effect of the
function is. I learn new things every day. I really appreciate your guide. This user
group list really beneficial to a lot people. You and many others generosity and the
valuable offering really can't be measured by the material object. I deeply appreciate
all your help.

RE: snmpd crashed by snmpwalk
Title: RE: snmpd crashed by snmpwalk
Hi
John:
Thanks for the input. I did some
experiment on my target machine. I asked the owner of the target machine to
check if there is any card has no IP address. He found one and added the IP
address.
The snmpwalk still crashed the
system. TheOS isLinux. I am going to build a net-snmp only snmpd
toexperiement that crashing is as you pointed.Doyou know is
there any patchavailable? Or if this isfixed in a latest version?
Mine is 5.1.1, quite new.From your experience is5.1.2 stable
enough?
I was told there is no such problem
in ucd-4.2.5. I may back ward my application toucd-4x. But there is some
know issues in ucd-4x too. Any suggestion?
Tx.

Jim, I had the same issue
but it was because of a bug in SNMP. If there is no ip address on the
interface, then it crashes. My OS is solaris.

snmpwalk
Hi Greeting:
I encountered one snmpd crashed due to the
snmpwalk timeout at the "IF-MIB::ifNumber.0 ". All the values before IF-MIB
were returned. But there is time out on IF-MIB.
I ran the snmpwalk to another host. It went
through okay. The two systems have different OS level of Linux. The snmpd was
developed and build on "Linux 2.4.18" and then was
installed on "Linux 2.4.21-mtd.1" All the
snmpwalk on "Linux 2.4.18" got returned values and didn't crash
the snmpd.
The system which was crashed by snmpwalk
has OS "Linux 2.4.21-mtd.1".
I have couple questions. If the OS level
difference is critical then why the MIB values before IF-MIB are
returned fine? It should not
return anything from the beginning, right? Could it be some specific device
interface hard to be recognized on the target machine which causing the
crash?
However the man page of "snmpwalk" said -
"If no OID
argument is present, snmpwalk will search MIB-2. If the network entity
has an error processing the request packet, an error packet
will be returned and a message will be shown, helping
to pinpoint why the request was malformed.
If the tree
search causes attempts to search beyond the end of the MIB, the message "End
of MIB" will be displayed."
This is how I ran
snmpwalk - without giving a OID or name.
So if there is some
unrecognized device "IF" on the target system most likely an error message is
displayed. Shouldn't caused the crash, right?
Any pointing to the
direction of searching the cause is highly appreciated. Thanks in advance.
