Hi,
I compiled Net-SNMP snmpd version 5.7.3 under FreeBSD 10.2. When I
start the snmpd with "snmpd -f -C -c /etc/snmpd.config" command, then
it listens on UDP port 161:
root@FreeBSD10:~ # sockstat -4l
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
root snmpd 29916 8 udp4 *:161 *:*
root sendmail 553 3 tcp4 127.0.0.1:25 *:*
root sshd 550 4 tcp4 *:22 *:*
root syslogd 359 7 udp4 *:514 *:*
root@FreeBSD10:~ # ps -fp 29916
PID TT STAT TIME COMMAND
29916 0 S+ 0:00.61 snmpd -f -C -c /etc/snmpd.config
root@FreeBSD10:~ #
However, if I snmpwalk this host, then it does not reply to SNMP
messages. Content of /etc/snmpd.config can be seen below:
root@FreeBSD10:~ # grep -v '^#' /etc/snmpd.config | grep -vE '^$'

root@FreeBSD10:~ #
If I use this very same configuration file with bsnmpd("bsnmpd -d -c
/etc/snmpd.config"), then host does reply to SNMP queries.
What might cause such behavior? Please let me know if additional
information is needed.
thanks,
Martin
