RE: rwcommunity in snmpd.conf ignored by snmpd ("unknown token" in debug output)

Thanks, Dave.

I thought about the unprintable characters, too; does it make sense that I would get similar messages (except that they reference "memory") when using --rwcommunity="prince" on the command line?

rwcommunity  prince$

[In the snmpd.conf file, that line looks like:   rwcommunity  prince   <-- no $.]

Including the debug info, it looks like:

daemon /usr/sbin/snmpd -DALL -Lf /var/log/snmpdmaster.log $OPTIONS $IPADDR:161

where:

OPTIONS="-LS 3 d -Lf /dev/null -p /var/run/snmpdmaster -a -I smux"

and:

$IPADDR is the sole IP address over which I wish to accept SNMP requests.

Hmmm....  You may have hit on something here.  I'm suspicious of that "-I smux"; I added that months ago and I can't remember why.  I think I was trying to make it forget about all the MIBs it knows about (since I'm servicing them another way).
