Hi
@tsabit,
First,can you please verify the version of linux you are using?
Second, please make sure that the snmp daemon is running by running by doing the following:
1.Go to your terminal on the remote / target linux host and run the following commnads:
Start the service....
Check if its running.....
expected output if its running:
Code: Select all
snmpd.service - Simple Network Management Protocol (SNMP) Daemon.
Loaded: loaded (/usr/lib/systemd/system/snmpd.service; disabled; vendor preset: disabled)
Active: active (running) since Wed 2017-09-27 11:52:40 CDT; 32s ago
Main PID: 20304 (snmpd)
CGroup: /system.slice/snmpd.service
└─20304 /usr/sbin/snmpd -LS0-6d -f
Third,make sure ports
for SNMP AND
for SNMP traps are open. This you have to check on your firewall permissions.
OR
You could simply run
to show you open or active ports and you will get this kind of output
Code: Select all
public (active)
target: default
icmp-block-inversion: no
interfaces: ens160
sources:
services: dhcpv6-client ssh
ports: 5666/tcp 161/tcp 80/tcp 5667/tcp 12489/tcp
protocols:
masquerade: no
forward-ports:
sourceports:
icmp-blocks:
rich rules:
If your port 161 and 162 for SNMP are not listed as active, then run command
Code: Select all
firewall-cmd --zone=public --add-port=<161>/tcp --permanent
to open,then
and check updates on the firewall again with
Lastly check make sure you don't have special characters in your community tmli(make sure its correct)and correct ports and IPs for your target host.
