SMSeagle not working

[Matte_Nilsson]

Hello All!

I have a strange problem with SMS-eagle (Firmware 4.41) SMSEagle is an offline hardware SMS gateway.

When i try to send an SMS from the transport GUI in LibreNMS, nothing happens.
But if i point out an apache2 webserver in linux instead of the gateway and copy the string that shows in the logfile and sends it to the gateway, then I get an SMS… strange…

Logfile in apache2 that works if i copy it to the addressfield of a browser and sends it to the gateway (X=Tel nr.)

[07/Feb/2023:07:27:35 +0100] “GET /index.php/http_api/send_sms?login=librenms&pass=LibreNMS&to=%2BXXXXXXXXX%2C&message=Testing+transport+from+LibreNMS HTTP/1.1” 404 434 “-” “-”

Hi!

Can you try to send the HTTP GET request manually from the command-line of the LibreNMS server using Curl (curl -v)? The output may give some more information.

With kind regards,
Ruben

Hello!

Thanks for the push in right direction!
The gateway was redirecting http → https and curl didnt like that.
so we added this to line 59 in the Smseagle.php-file:

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
