It looks like the SNMP query responses are simply never coming back.  Do 
the logs on the remote side reflect a request coming in?  Try to do a 
tcpdump(8) on all 3 machines:

# tcpdump -i [whatever interface] -n 'port 161'

Try disabling any firewalling services in redhat (netscreen, ipchains, 
whatever.)
