Fedora Core 10 and remote clients
  • This is just a quick note regarding the use of remote clients when the server is running on FC10. I set up port forwarding for tcp:6767 (on the router) but was still unable to connect from a remote machine. I was sure that I had made a mistake in the forwarding, but that wasn't the case. SElinux was disabled, but FC10's default set of iptables entries blocked other machines from connecting to the server.

    Since I trust my firewall's packet filtering, the solution for me was to disable iptables:
    "service iptables stop"

    I haven't verified this with a remote ember client (driving back and forth is best left to last). I was able to telnet into port 6767 from a remote machine. So I think I have things working.

    I seriously began to miss Ethernet hubs and the ability to drop a network analyser on a segment. Almost to the point of spending $50 for a used hub.
  • Thanks for letting us know how you solved this issue. In fact I think this is going to be an issue on most Linux systems as many distributions have been running a default-deny iptables policy for some time.

    I included a section on firewall instructions on the Cyphesis home page at http://worldforge.org/dev/eng/servers/cyphesis/ but I did not include any specifics as I am not sure how they vary from system to system, and I don't want to encourage less experienced users to turn off their firewall.

Howdy, Stranger!
