      Description

      Dear all,

      We have defined a Centos based image on the Fiware cloud platform and created some security rules for our integration tests.
      Please see below, all the ports seem working except 5050 and we need this for our Cygnus installation.
      We cant telnet to this specific port.

      Could you please help us with this problem?

      Thank, regards

        Hello Jose,

        Well we are trying to make this port open for a couple of days and I never saw it was open tbh..
        nor telnet from outside. nor wget localhost:5050 inside the machine..

        We have defined the port in iptables, Im not expert on system adm. area but to me, it should've worked

        Hello,

        By default CentOS works this way: It has its own firewall and this
        firewall is only opened for port 22. — We have to choosen to respect
        the CentOS philosophy and let the instances work the same way CentOS
        does because it is the way CentOS is expected to work.

        However, as you said, you may need some previous knownledge in system
        administration if you decide to use CentOS. To this aspect, Ubuntu is
        much easier and ready to use than CentOS.
        Regards,
        José Ignacio.

        Hello Jose,

        Yes I know Ubuntu is much more easier than Centos for sure but IDAS is suggested to be installed on Centos.
        And we need this port 5050 accessible from the internet.

        As I mentioned in my previous emails we have defined security group in Cloud portal as documented and added this port in iptables.

        But at the end we are not able to telnet or access this port...

        I've sent you the iptables and the rules previously.

        Do you have any advise for us? How can we open this port?

        Thanks kind regards
        Omer
