Funny: Ethereal to Wireshark Migration Guide
2008-05-07 12:05:00 Someone just pointed me at the Ethereal to Wireshark migration guide posted at http://www.wireshark.org/migration.htmlTh is is a shameless copy of this excellent (and funny) guide:MigratingMigrating from Ethereal to Wireshark is a long and arduous process. A typical migration project requires the following resources: * 1 (one) project manager (PMP certification preferred) * 1 (one) assistant project manager * 2 (two) pirate hats * 2 (two) system administrators * 1 (one) duck * 2 (two) network administrators * 4 (four) support staff * 2 (three) bags of hammers If you allocate full-time staff to the migration, it can take as little as six weeks for preparation and planning, and four weeks for the migration itself. Past migrations have resulted in some maiming and blood loss. A recent survey of human resources directors found that the amounts were within acceptable tolerances.The complete migration procedure is detailed below: 1. Place the pirate hats near the ...

Funny story: OSPF
2008-05-06 20:19:00 While working in a Support Organization of a networking company, I come across a lot of funny and interesting stories. Here is one of them.One of our customers, who's name we of course will not mention, opened a Support case. He complained that his routers were suffering from a high CPU load and thus the routing table was not up-to-date. Very quickly we came to the thought that is had to be because of OSPF not updating the hardware table quickly. At some point I asked him how many OSPF routers he had in the Area. His answer was 1500!!!One might say that 1500 routers in 1 OSPF area can occur in large networks. This sure can happen, but then it is time for a redesign of the network. Let me explain why this isn't a good idea.OSPF calculates the shortest path for each route. This means that if 1 router goes down, it will need to re-calculate the shortest path. With 1500 routers in 1 Area it will result in a lot of OSPF changes and thus a lot of re-calculations. Add all packets sent to... More About: Funny , Story
Major networking equipment manufacturers sued
2008-05-05 20:16:00 It seems that almost all major networking equipment manufacturers are sued by a company called Network-1. Named companies in the lawsuit are Cisco Systems, Cisco-Linksys, Enterasys Networks, 3Com Corporation, Extreme Networks, Foundry Networks, Netgear and Adtran.What happened?According to Network-1 they have been granted a patent for "Apparatus and Method for Remotely Powering Access Equipment Over a 10/100 Switched Ethernet Network”, also known as IEEE 802.3af PoE standard. Back in 2005 Network-1 has won a lawsuit from D-Link which resulted in a license agreement where D-Link will pay D-Link 3,25% of net sales to Network-1.What will happen?I cannot tell. Probably a long term litigation will start where each of the above companies fight their own war, or maybe a pack will arise where they all fight Network-1. My guess is that, because of the D-Link litigation, all companies will have to pay a certain amount of money as well. I will keep you all updated though.

More information on Juniper's switching product
2008-01-17 22:12:00 January 29th, that will be the date Juniper will launch their switching product. As the date is coming closer, rumors are increasing and I'll just add a little bit :)Juniper calls the switching line "Hurricane". This is the codename for their custom CPU. The switches are based on Marvell's ASCIC's. The line will consist of 6, 9 and 13 slots. All are 100Gbit/s per slot ready. There will be modules with 10x 10GE ports, but they will arrive later.I'm really curious what the product will look like, is capable of and what it will achieve. Only future will tell us, well see!

I heard it will be an OEM/ODM box, but nevertheless it will be Juniper branded.Then Foundry. Foundry has started recruiting people in the Netherlands to open up an European based TAC. Don't know if it is because Foundry can't find people in Silicon Valley or they believe it's cheaper in Europe...Last will be Extreme Networks. Their TAC organization will change a lot. It seems the current Level 2 TAC will be moving in a more customer facing TAC. More details will follow shortly. Question is, will it he...

Info - Hardened DHCP-based Edge Security with Extreme Networks
2007-02-06 14:50:00 On January 29th Extreme Network s announced that it supports Hardened DHCP-based Edge Security with ExtremeWare EXOS 11.6. But what is this exactly?The principle is actually very simple. Normally all devices you connect to a switch can get access to the network if they have an IP address. The IP address can be given out by DHCP, but you can also configure one statically (running Wireshark/Ethereal will reveal the network). Extreme Networks now has a feature called DHCP Snooping. When DHCP Snooping is enabled you force users to use a DHCP server. The switch will then inspect the DHCP request and the DHCP reply from the server. With this information EXOS will only allow traffic from this specific host. At the DHCP server you can configure which hosts are allowed to login and which ones are not allowed. If someone tries to bypass this behavior by configuring a static IP address, the user will be denied access and the administrator will get a notification.What are the advantages then? By...
