Hi,
I have a problem. I’m unable to do any SNMP request on my AS400 at the office.
I have tested several software that are able to check my AS400 and get SNMP information from it from my Dude server but The Dude server itself is unable to do so.
I have tested public as an SNMP community as well as my network’s usual SNMP community but none of them works.
I don’t understand how TheDude was able to get the MAC address of my AS400 and is unable to get its interfaces… That’s weird.
Can someone tell me what I can test please ?
Thanks for your help
No one can help me on this problem ?
That’s really weird.
bump… Am I the only one with my AS/400 issue ?
Just to illustrate my problem :
SNMP Walk with the Dude :
Smae SNMP Walk with MIB Browser :
Unfortunately we don’t have AS400 on our lab, we are unable to test it with this device.
Make sure you don’t have any firewall on AS400, you may try to run sniffer on computer where Dude is installed and check what happens with packets.
Thanks for your answer.
Both SNMP Walk are taken from the same computer (my Dude server) and the AS/400 doesn’t have any firewall integrated in it’s OS.
I’ll try packet capture and let you know the result if it can help you
Thanks
Hi,
I have finally done a Wireshark capture of what’s going on with my SNMP Walk on the AS400…
Who can I send it to in order to check what’s going on ?
I don’t really know how to read this but it seems that there’s an incorrect checksum in the UDP packet… but well, I don’t know how to read it.
I wouldn’t like to make it available to anyone on the forum as there’s my internal network IP address.
Is one of the gurus available to help me ?
Thanks
Do you have incorrect checksum for both SNMPwalks from Dude and from your program ?
Yes, I get the same errors using my other software but it doesn’t prevent it from getting the answers and continuing to send requests…
Here’s what I get from SNMPWalk in TheDude :
1 0.000000 frgucxxxx03.xxxxxx.xxxx asxxx.xxxxxxx.xxx SNMP get-next-request SNMPv2-SMI::zeroDotZero

If I understand what I read, they do not request using the same protocol ?
I have selected version 1 in The Dude, why do I read SNMPv2 ?
Does it help you ?
Bump… Nobody ?
No answer ??
Bump
The problem is still present in v3.0 final…
Well, I finally think it’s not gonna be solved by anyone…
I’m a bit disappointed
you should email MT support, because this is just a user forum
Thanks for the suggestion
I thought there wasn’t any support and that all the developers and else were coming here…
I’ll follow your recommendation.
Thanks
I have seen your thread and I am curious if you tried putting a specific OID in the dude and tried to just retrieve that one OID?
I don’t really have any other suggestions hope the devs come along with some help for ya.
and try change where from is sends snmp-query - server/local/agents
Sorry I didn’t answer before
I have tried all your suggestion and none work
Using a specific OID doesn’t do anything as well as changing server or local
I’m really stuck with this and don’t understand why it doesn’t work.
Obviously, it doesn’t want to use the same protocol as seen in my Wireshark capture…
Well, this looks like a dead end
I would love to have this solved in a way or another… Can anyone at The Dude help me ?
Please… help me in anyway
Bump again
