Hello guys...... i using snmp in uClinux .....it works with the default mibs but i need to do my own mib file ....... anybody knows how can i do that???............ one exemple how can i monitore a peripherial..... thanks Franz Wagner

where the uclinux jedis for help me !!!!!

I understand that the MIB file is part of the snmp standard and not spcific for NIOS or uClinux. So you should find in the internet what needs to be written there. -Michael

ok..... i post the result when i did work....... Franz Wagner

hi all!!!! i did a simple mib that read a one memory address......and i have success creating a skeleton of mib ( .c and .h) i run ./configure --with-mib-modules=mymod and it add mymod ok but when i did make in kernel i had many errors with doesnt appears when i make in my system pc........the problem is in cross compile......:( someone, sometime , already implement a own mib????? can someone help me did that ??????? thanks Franz Wagner

Hi,

Great job.
I'm interested to make snmp work on my uClinux too.

How do you manage to make it work? Do you do the following ?

You select snmpd
You select also net-snmp with "additional mibs options"
You put your modules in the additional mibs
Then when compiled you run snmpd on your target (snmpd -c <IPAddr of the target> -c public)

Is that's all ? Or do you provide additional configuration/mib files ?

On my side, I don't put additional mibs but I think that there is default mibs provided by snmpd. However I don't know if it need configuration files because my snmpd runs but it does not replies to a walk (timeout).
I activate the debug in snmdp (#define DEBUG in debug.h) and I see request but snmpd does not replies to it :

hi zben

follow me!!!

at menuconfig select custumize Applications.....

select net-snmp , build mini agent, build static, install mibs.

make

in your uclinux terminal do mkdir /etc/snmp

in this directory you do a snmpd.conf and put

rwcommunity public

save

at your desktop

snmpwalk -c public 192.168.100.137 -> put your uclinux ip

...........

if you want to do your own mib need other steps........

try it and report........

good luck

Wow great !!

My error was to select in menuconfig the "package" snmpd that provide also a snmpd application that override the snmpd provided by net-snmp.

So it works great (V1, V2c and V3).

Thank you very much, maybe I will come back with issue with custom MIBs
