Listen on specific port/ip for incoming connections?


(Grigorlu) #1

Hi all,

Can anyone help me with setting my container properly to accept incoming TCP connections?
The container hosts an Informix database server, configured to listen on port 9088 (olsoctcp/onsoctcp). It’s working properly but no network connections could be made, only such are possible via shared memory (onipcshm).

The container is being run with exposed ports 9088:9088 and I can verify these are working with ncat and telnet.
This is netstat output from the container where we can see no desired listening port is mentioned:
-bash-4.3$ netstat -an
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 127.0.0.1:10338 0.0.0.0:* LISTEN

So I assume I am doing something wrong in my configuration.
Can somebody help or point me to the proper docs where I can read about it?

Thanks a lot in advance!
