Re: snmpd 5.7.3 under FreeBSD 10.2 does not reply to SNMP requests

Hi,

for some reason I thought that bsnmpd configuration file is compatible
with Net-SNMP snmpd. While the Net-SNMP snmpd did not complain about
configuration file syntax(even if I started it with "snmpd -DALL -f -C
-c /etc/snmpd.config"), then it did not reply to SNMP requests.


regards,
Martin
