SNMP "Cannot find module" 3rd party MIBs

[Doubarry]

Hello,

since three days i am trying to convert my 3rd party MIBs to a zabbix tamplate.
I want to use the SNMPWALK2ZABBIX script by Sean Bradley, it looks good:

https://github.com/Sean-Bradley/SNMPWALK2ZABBIX

But when I try to run the command:

snmpwalk -v 2c -c public 10.0.1.253 1.3.6.1.4

I get the error message:

MIB search path: /home/david/.snmp/mibs:/usr/share/snmp/mibs:/usr/share/snmp/mibs/iana:/usr/share/snmp/mibs/ietf:/home/david/.snmp/mibs:/usr/local/share/snmp/mibs:/home/david/.snmp/mibs
Can't find module (MYMIB-MIB): At line 1 in (none)

So I follow the configuration of snmp for 3rd party MIBs:

https://wiki.debian.org/SNMP

My MIB-Files are now stored in /home/david/.snmp/mibs, /usr/share/snmp/mibs and /usr/local/share/snmp/mibs

But still the same error!

I also installed snmp-mibs-downloader but i still get the same error

My snmp.conf looks like:

# As the snmp packages come without MIB files due to license reasons, loading
# of MIBs is disabled by default. If you added the MIBs you can reenable
# loading them by commenting out the following line.
#mibs :
#mibs +ALL
# If you want to globally change where snmp libraries, commands and daemons
# look for MIBS, change the line below. Note you can set this for individual
# tools with the -M option or MIBDIRS environment variable.
#
# mibdirs /usr/share/snmp/mibs:/usr/share/snmp/mibs/iana:/usr/share/snmp/mibs/ietf
mibdirs +/home/david/.snmp/mibs
mibdirs +/usr/local/share/snmp/mibs

My last idea was to use the snmp command with the statement "-m MYMIB" like:

snmpwalk -v 2c -c public -m MYMIB:MYOTHERMIB 10.0.1.253 1.3.6.1.4

It also doasn't work....

Did I miss something?

Can someone help me, I'm out of ideas.

Thanks!
