In this installment of our Scalable Solutions series we are going to be reviewing one of the core components of EC2, the security group. We have found that our customers find that the elasticity provided by security groups allows them to build more resilient solutions and expand them as performance dictates it, with consistent security policies.

In case you missed our previous articles you may want to go back and review these great resources.

Fedora 20: Use PPTP VPN

Tue, 15 Sep 2015 00:00:00 +0000

I have had this one in the queue for a while (I don’t even run of Fedora 20 anymore). This one will be short and sweet, because there really isn’t a bunch of discussion that needs to go into it.

By default Fedora 20 will block outbound PPTP VPN connections.

 bash
 
 
firewall-cmd --direct --add-rule ipv4 filter INPUT 0 -p gre -j ACCEPT
firewall-cmd --direct --add-rule ipv6 filter INPUT 0 -p gre -j ACCEPT

Reload the rules.
