Package: nsca-client
Version: 2.10.0-1
Severity: important

Dear Maintainer,

The send-nsca client in bullseye is not working for me.

Here is the command I use:

echo -n 'shared-web-test;my-api-cert;2;CRITICAL - certificate expired' | /usr/sbin/send_nsca -d ';' -H nagios01.example.com -to 5

On BUSTER this command returns:

1 data packet(s) sent to host successfully.

Furthermore, the passive alert shows up on the nagios server.

However, on BULLSEYE the above command returns:

0 data packet(s) sent to host successfully.

Doing a tcpdump on the Nagios server nagios01.example.com I do see network
traffic when running the command on the BULLSEYE host, but the alert does
not register.

The nagios01.example.com server is running Nagios 4.4.6.
