hello, about one month ago my graphs stopped showing data and started reporting nan. i thought maybe it was my firewall (iptables). so i checked it out and found that some provisions weren't being made for snmp. so i added the following lines and restarted iptables: -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 161 --syn -j ACCEPT -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 161 -j ACCEPT -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 162 -j ACCEPT unfortunately that didn't solve the problem! i also tried restarting snmpd but didn't get any love there either. someone have a clue? oh, and like my subject line indicates, monitoring of the local server (the one that cacti resides on) is still working fine. thanks, chris. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
