 инсталирал и пуснал SNMP, но ми дава горната грешка. Ето и

Q: When I run mrtg, I get this error: 
SNMP Error:
no response received
 SNMPv1_Session (remote host: "ip.of.remote.host"
[ip.of.remote.host].161)
                  community: "public"

A: There are a number of reasons you would get this error: 
You are using the wrong community string. 
You are not in the access list of the box you are polling. 
The box you are polling is not running snmp. 
The box you are polling is down. 
You are not using the correct hostname or IP. 
 You will need to contact the sysadmin of the box you are
trying to poll to straighten this out.  

A: There are a number of reasons you would get this error: 
You are using the wrong community string. 
 tiq test-ove deto si gi post-nal predpoalgam sa ot 'make
test' pri instaliraneto na snmpd-to.
 Mislq, che community-to ti e problema (ili pyk si se olql s
 filtruvane ?! ). Pusni snmpconf, izberi snmpd.conf .. i
deistvai.
