Connection Cacti -> iDirect (VSAT)

[closen]

Hello, I just install cacti on a Centos 7 server.
The goal of this project is to connect the cacti server to the iDirect NMS server in order to have graph of the VSAT.
I'm stuck on an issue since 1 week and I read everything I could on this subject on internet so you are my last hope.
When I'm trying to connect Cacti to NMS server I need to make a SNMP connectio between them, the thing is that cacti can't connect with SNMP to the NMS Server.

As you can see with this image I'm able to ping the NMS server from cacti but the SNMP request isnt working.

Please let me know if you need any more information .
By the way I'm an intern so I'm learning everything right now

One of the following is wrong:

1) You have the wrong snmp information
2) You have a firewall blocking the packets
3) You monitored device has an acl blocking the Cacti server IP.
4) You are trying to access the monitored device using SNMPv3 advanced setting with php-snmp installed.

If using some complicated SNMPv3 setup, I suggest you upgrade to Cacti 1.2.21.

Hi Osiris,
Thank you very much for your reply.
1) I'm using the ip of the iDIrect NMS Server and I check for the community string so I'm sure that I'm using the good one.
2) I already try to disable firewall on the NMS Server for a short time but it wasnt working anyway.
3) It could be that but I've no idea how to check it can you help me ?
4) I'm using SNMPv2 at the moment.
Thank you in advance for your answer.

From the Cacti server, you need to get this working first:

Code: Select all

snmpwalk -v2c -c <yourcommunity> <yourhost> .1.3

Once this works, Cacti will start to work.

Thank you for your answer,
I have tried this request but its not working.
For example if I try to ping the NMS server from the cacti its working. But if I ping the cacti server from the NMS its not working.
I think thats why the SNMP request isnt working.
Maybe I'm on the wrong forum to Ask help about that . Please let me know.
This is my first Work in IT thats why I look like a noob.
Best regards,

When I check the rules of iptables on my NMS server I can see that Cacti IP is accepted.

If in a corp environment, firewalls can be oppressive.

Yes it's in a corp environment, can you give me some advices of where I should look ?
When I go to etc/sysconfig/iptables, I only find the new rules that I create to accept Cacti server IP.

Until snmpget works or snmpwalk works from the command line, you'll have to talk to your corporate Network people. They will know why. You could be natted or they are blocking SNMP.
