I started working in the Internet industry in 1995, when I helped to start up Computel Standby BV. I supported Computel while I was a student at Universiteit Twente. Computel started in Apeldoorn (NL) as a small ISP, started the Nederland.net foundation, and has grown into a server management company with its own small datacenter.
I became a RIPE Address Policy Working Group chair in May 2007, mostly because I am interested in the future of the Internet and I like to participate in things I think are important.
In May 2008 I left Computel and started working for Max.nl, which is a web application development company. In March 2010 I started my own company. I am focusing on internet infrastructure related subjects such as IPv6, routing and security. Since October 2010 I have been doing IPv6 related projects exclusively.

wifi is very slow, card RT5390 You say you tried everything on the net. Please describe what you tried exactly. People here probably can't read your mind... |

How do I configure ufw to only allow outgoing/established connections for a IPv6 network? I noticed you started a new question on this. Good :) The advice there to look at ESTABLISHED state is the right one. Unfortunately I don't have more detailed info for you now (writing on mobile phone) |

How do I configure ufw to only allow outgoing/established connections for a IPv6 network? The firewall rule I gave you allows the tunnel to work. To filter the content of the tunnel you'll have to create IPv6 forwarding rules that decide which traffic gets forwarded over the tunnel. |

How do I configure ufw to only allow outgoing/established connections for a IPv6 network? Looks right if w, x, y and z match your tunnel setup :-) |

Could not display “/media/…”.The location is not a folder Sounds like a mounting error then, but can't tell you what went wrong based on the information you give here. Can you check /var/log/syslog to see if there is an error message about htis there? |

WUBILDR.mbr file error on windows 7 and windows 8 : UEFI boot Please describe the steps you have taken so far. "I have tried a lot" and lots of exclamation marks are not useful for people who want to help you. |

Why are my fonts bold? Deleting fonts is not the ideal solution, but thank you for sharing the option :-) |

Why does IPv6 kill my network in Ubuntu 12.04? You'll need to provide more information about your configuration and the changes you made to set up IPv6. |

ipv6 just wont go away 12.10 server PS: watch out if you disable IPv6 support in ufw. If the ipv6 module is loaded in some other way it will result in a system with IPv6 enabled but without an IPv6 firewall. It's better to leave IPv6 enabled and secure. More and more applications and protocols are using IPv6 these days, even if just on the local link (the addresses that start with fe80: are always available on every interface). |

cannot delete IPv6 default gateway Link-local addresses are often used for determining the next hop. Next hop IP addresses are only used to find the layer-2 (usually ethernet these days) address where to send the packet to, and link local addresses are fine for that. |

sysctl no such key error for ipv6 parameters @anirvan: probably another cause for the delay then... (one thing you might want to check: do scripts on the http site make secure connections (i.e. encrypted connections to a database server) when executed? Encryption is used in a lot of places these days ;-) ) |

sysctl no such key error for ipv6 parameters If it is slow with ssh, https etc. it might be an entropy problem. Encryption needs good random data, and I had lots of delays because of lack of random data (entropy). Keep an eye on /proc/sys/kernel/random/entropy_avail. When it gets close to 0 it will delay your encryption and thus your ssh, https etc. |

IPv6 over PPPoe? Should be no problem. IPv6 with PPP (and therefore PPPoE and PPPoA) just create a link. Everything else just works like your local network :-) |

IPv6 over PPPoe? Oh, and 6deploy.org/workshops/brazil_20080526/autoconf_and_dhcpv6.pdf might also contain useful information! |
