in reply to strange snmp question

Hi, insaniac

thanks for your reply.You can see from the trace, 99.140.12.9 does reply "icmp port unreachable " to 99.1.64.65. So I think there isn't any acl between the machines.

I tried snmpget ,and get same result.Maybe the linux has some problem.

I will try to solve the problem. thanks again

    No sweat man... hey, maybe a router/firewall is denying your ICMP replies towards that specific router? try finding a router/device which you CAN query over SNMP (maybe on the same network as the host you're performing the query from)..

    good luck and happy hacking! :-D

      Hi insaniac,

      I got the answer.There is firewall installed on the linux machine.So it is deny all the incoming udp (snmp)packet.

      After I use "/sbin/iptables -F" to stop the firewall.It is work normal.

      thanks!
