Hello, I'm wondering if anyone else is seeing the same issues I'm seeing here. I have recently upgraded one of my systems from 4.4 to 4.5 and ever since then I cannot get snmp to work. I am monitoring the interface traffic. Please keep in mind the firewall/router I do the same thing without any issues for 4 interfaces and it is still at 4.4 and doesn't have any issues. If I try an snmpwalk I get the following; ~~~~~~~~~~~~~~~~~~~~~~ snmp $ snmpwalk -v 1 -c <string> localhost system Timeout: No Response from localhost snmp $ snmpwalk -v 2c -c <string> localhost system Timeout: No Response from localhost ~~~~~~~~~~~~~~~~~~~~~~ snmpd is up and running according to the system ~~~~~~~~~~~~~~~~~~~~~~ snmp $ service snmpd status snmpd (pid 7884) is running... ~~~~~~~~~~~~~~~~~~~~~~ snmp.conf file hasn't changed since I last changed it in Jan. I'm stumped as to why it is not working and don't want to upgrade the router/firewall box, which is working without any issues, until this get fixed. Can someone point me to what I am missing or point me in the right direction? Thnx! Oh, here is the output from uname ~~~~~~~~~~~~~~~~~~~~~~ snmp $ uname -a Linux <host> 2.6.9-55.EL #1 Wed May 2 13:52:08 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux ~~~~~~~~~~~~~~~~~~~~~~ SNMP version installed; ~~~~~~~~~~~~~~~~~~~~~~ snmp $ rpm -qa | grep snmp net-snmp-libs-5.1.2-11.EL4.10 net-snmp-utils-5.1.2-11.EL4.10 net-snmp-5.1.2-11.EL4.10 net-snmp-libs-5.1.2-11.EL4.10 ~~~~~~~~~~~~~~~~~~~~~~ If there is anything more that you need, I will supply it. Thnx again. -- Regards Robert Smile... it increases your face value!

I've updated about 10 servers this past week from 4.4 to 4.5, all running snmp, and haven't had any issues.

Thnx!see /etc/hosts.allow and /etc/hosts.deny, the 4.5 upgrade add tcpwrapper support to snmpd (which wasn't the case before).. see "rpm -q --changelog net-snmp-utils" echo "snmpd: 127.0.0.1" >> /etc/hosts.allow
