Nagios Support Forum

Hello,

We are experiencing issue getting our isms moden to work on our new CentOS 7 Nagios XI server. On our old Nagios XI CentOS 6 server, it works fine. The only error message we get is:

error occurred sending the test SMS message

telnet to our isms modem on port 81 works fine, so there shouldn't be any networking / firewall issue.

Is there any debug logging we can enable and where would these logs be written to?

Grtz

Are both XI machines running the same version of the component? Did you create a unique user for each XI machine? Testing some of the Multitech units I found that using the same account on two machines can sometimes be an issue.

Looking at the code, the error message can be triggered if a response isn't returned or a valid one isn't returned. It may be more telling to get a tcpdump of the communication between the two:

yum -y install tcpdump
tcpdump -s 0 -i any port 81 -w multitech.pcap

Hi,

it's working!
The tcpdump helped us to find out that we got an "Unauthorized" message back.
Although we were able to do a telnet to port 81, we needed to add our new subnet to the "Allowed Networks" under administration on the configuration website.

After doing that, we still had an issue and I started debugging by copying the exact URL from the tcpdump in a browser and using it with curl on linux.
Problem was that the new user which I created had a special character ('=') in the password.
So, I ended up using the old user again with a more simpler password and it worked.

Thanks for the tcpdump tip.

Regards,
Peter

Glad to hear!
