Hello Orion, I actually rather like the new CentOS 7.2 system better and would like to not remove firewalld. We will try Gilles' suggestion and see what happens.

CentOS 7.2 no longer seems to bother with the IPv4 firewall, so you can't do: > > > > # service iptables save > > # service iptables stop > > # chkconfig iptables off I'll just note that you can either embrace the new firewalld config (and use firewall-cmd to open your needed ports) or you can remove firewalld and install iptables-services and go back to the old iptables method of configuring the firewall. If you don't want a firewall at all, just remove firewalld. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane or...@nwra.com Boulder, CO 80301 http://www.nwra.com _______________________________________________ users mailing list us...@open-mpi.org Subscription: https://www.open-mpi.org/mailman/listinfo.cgi/users Link to this post: http://www.open-mpi.org/community/lists/users/2016/05/29160.php
