Task List Tracker for the Mac (DIY Version)
As a Mac user, how do you keep track of the tasks you need to complete? I find myself swamped in things that need doing and every day more things get added to my list. The problem is, in the past I’ve relied too much on my memory to keep track of what I need to do, and I’m sadly aware that there are more things on my task list than I can keep track of, and all too frequently I get into work and think “What was I going to do this morning? I’m sure there was something high priority, but…”
It should be easy, you’d think, to maintain a list of tasks, assign some kind of priority, and have that list readily accessible while using my computer. I suspect there’s an app (indeed, that there are many apps) for that, but while I have tried a few, somehow I’ve not managed to integrate them into my daily workflow. I spoke to a colleague about this, and he said that he keeps a text file on his Desktop listing all his open tasks, and he updates it as needed. If it works for him, maybe it would work for Continue reading
Solving the Problem in the Right Place
Sometimes I have this weird feeling that I’m the only loony in town desperately preaching against the stupidities heaped upon infrastructure, so it’s really nice when I find a fellow lost soul. This is what another senior networking engineer sent me:
I'm belonging to a small group of people who are thinking that the source of the problem are the apps and the associated business/security rules: their nature, their complexity, their lifecycle...
Sounds familiar (I probably wrote a few blog posts on this topic in the past), and it only got better.

Our colleague Jan Žorž from the Deploy360 team will be presenting at the 14th Eurasia Network Operators Groups (ENOG 14) on 9-10 October 2017 in Minsk, Belarus. This is being preceded by workshops on Best Practices in IPv6 BGP and DNSSEC Operations.
Jan will be talking about his real life experiences with NAT64/DNS64 and will be demonstrating the NAT64check tool on Monday evening (17.00-18.15). Following after his talk is a BoF on the Internet-of-Things (18.30-19.30), which is also sure to include discussions about the importance of IPv6 to scale the expected many billions of devices in future.
We’d also like to highlight the Cloudflare update on IPv6, DNS, DNSSEC, CA certs from Martin Levy (Cloudflare) on the Tuesday (10.00-11.30), who seems to be managing to cover just about all the Deploy360 topics in one talk. And for routing security, Kirill Malevanov, (Selectel) will be discussing his experiences of IPv4 prefix hijacking.

Support New Ways of Working To Connect The World
The World Telecommunications Conference (WTDC) begins today. This is a key moment to remind the world that together we can shape a digital future that puts humanity at the heart of the Internet. But to do this we need your help.
Help send the message that to close the digital divide we’ll need new ways of working, new ways of thinking, and new policies support it all.
Much of what we are speaking on at WTDC serve as real-world examples of the kinds of things we need policy and decision makers to support – community networking being a key focus.
We will keep you up-to-date on what is happening and what we need to do next the conference.
Here’s how you can help:

BGP ADD-PATH – Summary
Hi,
First things first, I have been getting a lot of requests to upload the lab’s which i illustrate as is, so i shall be uploading them to a Github page with initial and final-configs and Instead of vagrant i shall be using EVE-NG as a tool so that you guys can import them easily.
Going through Fabric-Path and CLOS concepts, got myself started with 3 Stage Clos and as a part of understanding it, discovered something.
Why – To make sure Servers at one end have equal cost path to the servers-at other end, at scale the spine accordingly optimizing the CAPEX.
Simple words, in the below topology, we need to make sure that R6 has equal cost to R7 and vice-versa.
Protocols and setup
-> OSPF for the entire domain and Ibgp to peer between RR (R2) and all other loopbacks, we use OSPF so that Ibgp peering will be over Loopback and also for load-balancing protocol Next-hops
-> Default routes on R6 and R7, load-balance (per-packet) on all-routers (where technically required)
-> R3 AND R4,R5 has static back to loopbacks of R6 and R7 respectively, advertising them into OSPF will defeat the purpose obviously Continue reading
Introduction to DHCP (Dynamic host configuration protocol)
Well Routers, servers, other key nodes require specific or static IP address and Clients can use an IP from a pool of available addresses. Minimum host configuration for Internet:
- IP address
- Subnet mask
- Default gateway
- DNS server IP
DHCP allows network administrator to assign a pool of available IP addresses for clients with additional configuration information such as default gateway, DNS IP, WINS IP, domain names
Addresses are leased, Cisco default is 24 hours
 |
| Fig 1.1- DHCP Server |
DHCP process
· Client boots up, sends a DHCPDISCOVER broadcast
· All available DHCP servers respond with DHCPOFFER containing proposed IP address, lease time, DNS IP; server checks that IP offered is not in use before making the offer by issuing a default 2 pings

“Keep those eyebrows up!” – Cybersecurity at the Global Women’s Forum
News of cyberattacks is slowly becoming a new normal. We are still at a stage where high-profile cases, like the recent attack against the American credit reporting company Equifax, in which 145.5 million users had their personal information compromised, raise eyebrows. But we need those eyebrows to stay up because we should never accept cyber threats as the new normal.
This week in Paris, hundreds of leaders met at the Women’s Forum to discuss some of the key issues that will shape the future of a world in transition, including cybersecurity. But this topic is not just a concern for the experts – it’s a concern to all men and women leading any business today.
New risks on the horizon
A recent report by the Internet Society, “Paths to Our Digital Future”, points out that now is a big moment for the Internet. The revolution we already see could accelerate in the coming years, not only due to the increasing digitalization of services and businesses, but also through the expansion of objects being connected to the Internet – the Internet of Things (IoT). By 2020 more than 20 billion “things” could be connected.
Suddenly it’s not only Continue reading

Traceroute Lies! A Typical Misinterpretation Of Output
Sometimes a user with performance issues will proudly present me with a traceroute and point to a particular hop in the network and accuse it of being the problem because of high latency on the link. About 1 time in 1000 they are correct and the link is totally saturated. The other 999 times, well, let me explain.
Traceroute Output
Here’s a typical traceroute I might be sent by a user (IPs and hostnames are altered to protect the innocent):
