Hallo,

my problem: I want to install an snmp daemon on an openWRT (kamikaze
8.09.2) (running on an Avila GW2348-4). I installed snmpd, libopenssl
via opkg

my snmpd.conf:
rwuser testuser
createUser testuser MD5 testuserpw DES testuserpw

starting snmpd with: /usr/sbin/snmpd -c /etc/snmp/mysnmpd.conf

everything is fine as long as I don't use authPriv.
snmpwalk -v 3 -u testuser -l authNoPriv -a MD5 -a testuserpw -x DES -X
testuserpw 192.168.0.xxx
-> works.

snmpwalk -v 3 -u testuser -l authPriv -a MD5 -A testuserpw -x DES -X
testuserpw 192.168.0.xxx
-> snmpwalk: Decryption error

I tried to put authPriv into the snmpd.conf (rwuser testuser authPriv)
but this changes nothing.

Any ideas?

pre-thanks
Martin

That sounds suspiciously as if the openWRT package has been
compiled *without* OpenSSL support. You probably need to talk
to the openWRT people to check this, and find out how to re-compile
things to include OpenSSL.

Hi martin,

I'm struggling with same issue since quite long, and didn't found solution for this. This is quite a old thread but I need help if you got any solution for it, please post the solution to fix it.

I'm using OpenWrt 15.05 ("Chaos Calmer").
