Please, ANSWER this question AT https://ask.fiware.org/question/386/cloud-security-groups-not-working-with-centos/
Question:
Cloud security groups not working with CentOS
Description:
I've created a CentOS Virtual Host and I've opened the port 5050 in my security groups, however I can't access that port in my Virtual Host.
I've tested the same thing with Ubuntu and there was no problem with it.
It is very easy to reproduce.
You create a new security group and you add a rule to open port 5050 from 0.0.0.0/0
Deploy a new CentOS instance. When it is up you can run a netcat process listening in that port.
nc -l 5050
From any remote host, you try to telnet that host
telnet $MYHOSTIP 5050
It wont work. However if you do the same steps using Ubuntu instead of CentOS it will work without any problem
Any help would be appreciated.
