In the RedHat Linux host, the test script was not received.
echo -n ‘{ “version”: “1.1”, “host”: “example.org”, “short_message”: “A short message”, “level”: 5, “_some_info”: “foo” }’ > /dev/udp/127.0.0.1/10501
However, in the graylog container, it works with the following test scripts
echo -n ‘{ “version”: “1.1”, “host”: “example.org”, “short_message”: “A short message”, “level”: 5, “_some_info”: “foo” }’ > /dev/udp/127.0.0.1/12201
Any hints why it does not work in the Redhat Linux host. Many thanks.
