Thanks for your tips. Here's what I tried on my Etch box:
Etch:/# netstat -natup | grep 161
udp 0 0 0.0.0.0:161 0.0.0.0:*
6007/snmpd
So that seems ok.
I've created this bare settings file in /etc/snmp/snmpd.conf
# /etc/snmp/snmpd.conf
# sec.name source community
trapsink readonly localhost public
# sec.model sec.name
group MyROGroup v1 readonly
# incl/excl subtree mask
view all included .1 80
# context sec.model sec.level match read write notif
access MyROGroup "" any noauth exact all none none
# end of file
And stopped en started snmpd (restart only stops snmpd, this seems like
a bug). And tried snmpwalk again:
Etch:/# snmpwalk -v 1 -c public localhost
End of MIB
So again no results. I'm kinda lost here. I might purge the snmpd
package and try reinstalling it, let's see where that gets me. Or does
anyone spot the error?
