The skinny on SD-WAN based data centre to data center connections

Many SDWAN architectures are based on a hub and spoke configuration. Although spoke to spoke communications are also possible via a matrix topology, the fundamental driving force on this not being important is that the most significant traffic flow is always between a branch office and the data centre and not between branches. A cited reason for branch to branch communications is alternative paths or resilience. Practically, faults at the branch office are lollipops. The last mile connection itself fails and there is no east or west bound path alternative on the failed last mile. As an example, if fibre fails then wireless backup would be the only alternative and not an alternative fibre path. However, in a data centre location these types of alternative fibre paths are available but it is disingenuous to assume that a data centre and branch office would have the same level of connection ability or requirement.

easywall - Web interface for easy use of the IPTables firewall on Linux systems written in Python3.

Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.

No Scrubs: The Architecture That Made Unmetered Mitigation Possible

When building a DDoS mitigation service it’s incredibly tempting to think that the solution is scrubbing centers or scrubbing servers. I, too, thought that was a good idea in the beginning, but experience has shown that there are serious pitfalls to this approach.
