Interop: Firewalls, Booth Babes and Unicorn Poop

Now that I’ve returned from the whirlwind that was Interop Las Vegas, I thought I’d share some thoughts about my experience as a speaker and attendee. First the good: The UBM staff was awesome and I appreciated the chance to pontificate on one of my favorite subjects, firewalls. Thanks to some quick thinking by the […]

When Tech Meets Business

"I have had the pleasure of having Himawan as part of my team for a total  of 3 years, first two years in the Carrier Ethernet practice as an NCE,  and later on as part of my Advanced Services Africa team where Himawan worked as a Solutions Architect.

Himawan is unique in the way that he not only contributes with extremely  good technical knowledge (for which his triple CCIE is a proof), but he also provides the combination of very good consultancy and business skills, which makes him extremely valuable not only in meetings with customer engineers, but also in meetings with customer senior management.

What I value most with Himawan is his never give up attitude, it doesn't matter how complicated problem, how challenging business environment, or how short timelines, he always jumps into the challenge and finds a way to resolve the issue.

I can strongly recommend Himawan for any position where the combination of technical and business skills is required, and if I had a position open requiring these skills I would see Himawan as the perfect hire."

Cisco AnyConnect VPN with LDAP integration


I spent some time recently building anyconnect VPN on an ASA 5525-X and integrating it with LDAP. It could be fairly quick and simple if you have the necessary information to build out an aaa-server for LDAP and match the attribute maps for LDAP service.

Integrating VPN with LDAP involves two phases:
1. Build an aaa-server for LDAP (multiple aaa-servers for load-balancing/redundancy) and then associate the LDAP server to the VPN tunnel-group.
2. Build LDAP attribute maps for determining what AD user gets associated to what VPN Group-Policy.

Phase 1 : aaa-server

Before building your aaa-server, you need to grab some information from your AD server. This includes the following:

1. AD server IP address
2. AD server type (microsoft etc)
3. LDAP (389) or Secure LDAPS (636) port

Create aaa-server 'LDAP' that uses protocol ldap.

aaa-server LDAP protocol ldap

Assign an IP address / Server (dns resolved) name to that LDAP server.

aaa-server LDAP (inside) host dc01

Note: Here the ASA realizes the dc01 server has an IP address which is internal to the ASA, hence it puts it in the 'inside' interface.

Since we use LDAPS and require LDAP over SSL, and the AD server is a Microsoft Continue reading

The Last Question

Please find my complete interview with IT Certification Master: Why Network, Skill, Experience Matters Most. Thank you to Mirek Burnejko for the opportunity.

And below is the last question from the interview:

MB: You are also a co-founder of several organizations: GEM Foundation, Jawdat Teknologi Indonesia and CCIE93. Can you describe us these new ventures?

HN: This is my problem: there are 250 million people in Indonesia, and there are only less than 200 CCIEs. I’m planning to solve that problem. And it doesn’t mean I will make everyone from my country as CCIE. Nor I will teach CCIE class. I want to do more. I want to help Indonesian students and young professionals to become globally competitive professionals. So they can compete in global market like me, or stay in Indonesia to work on challenging project currently being done by professionals from outside the country (expats). And the solution must be scalable. That’s why I founded a not-for-profit organization GEM Foundation (GEMFo) early last year with several other Indonesian professionals who work outside the country. I spent my personal time to visit schools and universities to share global view from my own experience working abroad for more than 10 Continue reading

[Quality of Service] Part 3 – Nexus 1000v: The Servers are Doing QoS Now?!?

I’m going to talk a little bit about performing QoS functions from within the Nexus 1000v. Since it’s been awhile since I made the last post in this series, a recap is in order: In my first post, I explained what the different types of QoS policies were in the context of Cisco’s MQC In my second post, I went through the actual configuration on specific platforms like the Cisco Nexus and Unified Compute platforms, as well as a brief mention of vSphere’s participation, but less on the QoS aspects and more on MTU.

Identifying Introverted Tendencies

It’s no secret that our industry is full of those with interesting eccentricities. These characteristics are found in varying degrees with those we come into contact with daily. The extremes of these often manifest themselves as a general perception of those in technology. This even happens as technical characters are portrayed television. One example of this […]

Open Source Switching

There’s been a ton of attention lately around the concept of using commodity hardware in an area of the industry that is currently dominated by proprietary ASIC-based solutions - networking. When it comes to crossing paths between open source and networking, the obvious low-hanging fruit has been software-based switching solutions like Open vSwitch, or cool ways to make virtual switching do bigger, better stuff for cloud providers like Openstack Quantum (awesome, by the way).

Book Review: A Primer of Multicast Routing

I was recently in need of a refresher on multicast routing, so I picked up Eric Rosenberg’s A Primer of Multicast Routing (Springer Briefs in Computer Science). The overall plan of the book is excellent, starting with a basic overview of what multicast is (and does), including why multicast is more efficient than unicast for […]

What is static floating route

How does the internet work - We know what is networking

Static floating route is static route like any other but with added administrative distance in the configuration R1(config)#ip route 172.16.10.0 255.255.255.0 10.10.10.2 200 Defining the packets route using Static Floating Routes is very interesting topic so I decided to give you a short description of Static floating routes with an example.

How to Turn Your IOS Router Into a Pr0n Server (Pr0n Not Included)

No, really! Did you know that your IOS-based router is capable as acting as a static webserver? Below you will find the steps necessary to turn a GNS/Dynamips box (or any ‘testlab’ machine) into something that can serve basic HTTP/HTTPS content. Due to the security implications of the steps below, it’s not recommended to do […]

[Virtual Routing] Part 3 – Router Redundancy in VMware vSphere

My post a few weeks ago about the CSR 1000v made a pretty big splash - it’s clear that the industry is giving a lot of attention to IP routing within a virtual environment. No doubt, Vyatta is largely credited for this, as they’ve been pushing this idea for a long time. When Brocade announced that they were acquiring Vyatta, and Cisco announced they were working on a “Cloud Services Router”, this idea became all the more legitimate, and as you can tell from this series, it’s of particular interest to me.
