It should work like this. I've used it just for a test recently, to see
if it was possible to isolate a daemon into a network-less namespace (no
NIC except "lo"), and with haproxy connecting into that namespace. And
yes, it works. I'm not a namespace user at all so I had to use "ip netns"
with the man page opened and after trial and error I managed to make it
At least you need to enter your customer namespace and issue
"netstat -ltnp" to ensure that your zabbix server is properly listening
to incoming connections, otherwise it will obviously never work.
Hoping this helps,
