net-snmp mib files

Hi

i'm interested in compiling my own MIB in uclinux.. my snmp works fine but im not able to add my own MIB .. i followed the net-snmp tutorial but no avail ...

regards

Khushboo

hello Mr khushboo_q,

I'm sorry for the delay in reply........

to do you ow mib first you need to write your FILE-MIB.txt

this file is used to generate a c skeleton...

and look like this

now you need a linux machine to walk away......

install net-snmp .... and put your mib at mibs directory /opt/net-snmp/mibs

and run mib2c

$mib2c LINEAR-MIB.txt:linearProject

this generate two files : linearProject.h and linearProject.c ......

you need modify the .c file to do what you need.......

and put this file at nios2-linux/uClinux-dist/user/net-snmp/net-snmp-5.2.1/agent/mibgroup

add your mib at menuconfig and voila.....

good luck

Hi all,

I have a system with a nios2 and a network interface (Altera Triple speed Ethernet MAC).

I use 2.6.30 kernel on my board and net-snmp 5.2.1.

I can see my network interfaces using ifconfig :

--- Quote Start ---

/# ifconfig

eth0 Link encap:Ethernet HWaddr 00:15:12:00:15:88

inet addr:192.168.0.110 Bcast:192.168.0.255 Mask:255.255.255.0

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:1400 errors:0 dropped:681 overruns:0 frame:0

TX packets:400 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:205531 (200.7 KiB) TX bytes:33239 (32.4 KiB)

Base address:0x400

lo Link encap:Local Loopback

inet addr:127.0.0.1 Mask:255.0.0.0

UP LOOPBACK RUNNING MTU:16436 Metric:1

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

So the systems know interface statistics.

But I wonder why net-snmp is not able to handle these statistics automatically.

I have the following :

So it is ok for the system mibs and some other infos, but nothing about my network interface (eth0)...

My (simple) config :

--- Quote Start ---

rwcommunity private

rocommunity public

sysServices 2

sysDescr XXX

interface eth0 6 100000000

--- Quote End ---

As you can see I tried to add "interface eth0 6 100000000" to my conf file but it is not recognized by this version of net-snmp

I can't figure out if net-snmp is able to "automatically" retrieve network interface, or if my issue is related to the nios2 linux environment I use. I googled a lot for nothing.

Do I need to add a MIB in menuconfig (I tried mibII/ifTable mibII/interface mibII Rmon if-mib...) ?

Do you have any idea ?

Thanks

I think that I need succeed to add modules in menuconfig : mibII/ifTable mibII/interface mibII Rmon if-mib

But there is compilation errors, and if I let only mibII/interface snmpd hangs the system ...

Hello mr zben

try add your mib at computar that you do snmpwalk (i dont remenber what directory but look like Mibs) and add that mib at /user/net-snmp/.../mibs

good luck
