snmpd woes

[Net Llama!]

I'm trying to get snmpd working on several systems with the goal of then 
using MRTG to graph their network traffic.  Unfortunately, I can't seem to 
figure out how to configure snmpd to listen on anything but localhost.

If I run:
snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex

I get the expected response.  But if I substitute localhost with the IP or 
hostname of a different system, I end up with a timeout.

I'm running snmpd with the following command:
snmpd -Lsd -Lf /dev/null -p /var/run/snmpd -a

I've spent the past hour googling, and can't seem to find anything 
obvious, even though this seems like a trivial configuration issue.  Help?
