I installed openstack --allinone on one computer (Say A). Then, I added two more compute nodes(Say B and C) on this. Everything is working fine. But now, for some other reason I want to start HTTPServer on computer B and access it from computer X and Y which are different from A,B & C. Now after running HTTPServer on computer B, I'm not able to access it from computer X and Y. Giving Error 'No route to host' Although from computer B, I can access HTTPServer of computer B. Please help. -- Vedsar Kushwaha M.Tech-Computational Science Indian Institute of Science _______________________________________________ Rdo-list mailing list Rdo-list(a)redhat.com https://www.redhat.com/mailman/listinfo/rdo-list To unsubscribe: rdo-list-unsubscribe(a)redhat.com

Try adding the rule manually for your webserver iptables -I INPUT -p tcp --dport 30001 -j ACCEPT Depending on what you want to use you can add it to the settings: /etc/sysconfig/iptables for the iptables service or /etc/firewalld/ for firewalld. For sake of debugging you could also use 'iptables -F' to delete all rules.
