Sake Blok

My interest in Networking was first raised when I started working for one of the first ISP's in The Netherlands (back in 1995). My L2/L3 knowlegde was gathered while working for a large bank. I then switched teams within that bank to manage their redundant internet gateway based on a loadbalanced firewall cluster, loadbalancers, ssl-offloaders, caches and proxies.

In that time (2000) I started using Ethereal to troubleshoot problems within that environment. After my switch to a reseller, my skills developped towards bug-chasing and Ethereal/Wireshark has been an invaluable tool for me. I use it on a daily basis.

In february 2006 I wished to be able to filter on the "X-Forwarded-For:" http-header and joined the mailing-lists. First I wanted to ask for that functionality, but then I realised that I might be able to add it myself. Well, one thing led to another and after submitting a few of my own patches, I started working on bug-reports too. Resulting in being invited to the core development team in august 2007.

I live in The Netherlands near Amsterdam and work as "Research and Development Engineer" at ion-ip in Veenendaal. In my job I am involved in troubleshooting complex networking problems in Application delivery infra-structures. This involves quite a bit of bug-chasing :-). I am also involved in putting new and existing products from our vendors on a testbed in our testlab (which I maintain as well).

Main development areas

As I am more a networking person than a programmer, I mainly contribute by solving issues I encounter while working with Wireshark. I also submitted a few enhancements and solved some bugs reported by others. My development skills are growing, but for now I consider myself skilled at looking at what other people have built and reusing and combining things to solve the issues I want to solve.
