HI,
I just found out that if the firewall is turned off using the following command, the subscriber receives the message.
sudo systemctl stop firewalld
However i would like to enable the firewall back and still be able to use opensplice dds. How to do this? Add an exception for opensplice services in firewall?
Hi @djacob91 more information about port control when using DDSI as network service can be found in section 7.3.3 of the deployment guide
Thank you @ThijsSassen
Solved the issue by adding/opening a couple ports in the firewall.
Here are the commands used.
# firewall-cmd --permanent --add-port 7400-7649/udp
then restart firewall using
# systemctl restart firewalld
to verify the specified ports are open, use the following.
# firewall-cmd --list-ports
Hope this helps someone like me who is a newbie to all these.
Regards DJ
Hi,
I was trying to run the helloworld example in linux (RHEL8). Previously i was able to run similar examples on windows. I Have successfully build the example using the make file. However the subscriber is not receiving any data. The publisher successfully publishes the message though.
I have tried this for both the c and cpp , but the result is same. What could be the issue here? Do i need to worry about any firewall settings or something of that sort?
Regards DJ
