This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started). Mostly now the topics are about IoT and SD-WAN.

The power of SD-WAN
While working for a network operator one of the things I realised was that of all the network outages which the Network Operations Centre
(NOC) had to deal with, 80% of them were related to power. This is
related to the CPE losing its power either from a trip, cabling being
unplugged, or utility side outage. Of the remaining 20% of network
outages, 80% are resolved by recycling the on premise networking kit.
This implies only 4% of networking outages actually involve
troubleshooting. However, in SDWAN development, vendors concentrate all
of their efforts in that 4% and ignore the other 96%.
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. Access this neat software over on github: easywall
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.
