A team of researchers led by the University of Tokyo have managed to send files over Internet2 at super-fast speeds.

During the annual Internet2 Spring meeting this week managed to send to send data along a 30,000 kilometer path at a rate of 9.08Gbps, which equals 272,400 Terabit-meters per second.

Palm Inc. officials have announced the smartphone and handheld maker is to develop a new operating system for its devices, based on the Linux operating system. Palm used the “Palm OS” operating system and has also put out Treo smartphones running Windows Mobile. “We think there is a big wave coming in this whole mobile computing revolution, which is becoming a bigger part of the overall mobile phone business. We have an enormous opportunity going forward,” he said at a meeting with analysts in NYC. “You can expect us to do business development around the world.”

Palm Chief Executive Ed Colligan said the new operating system was in the works for years in secrecy. There have been multiple reasons for Palm’s efforts to develop a new operating system. First of all, the Sunnyvale-based company doesn’t own the Palm OS and spent $44 million last year for a permanent license to use it. Furthermore, the operating system was subject to criticism for its lack of major improvements over time. The Palm OS was owned by spin-off Palmsource, which was acquired by Access.

Two-in-one DNS server with BIND9

• This tutorial shows you how to configure BIND9 DNS server to serve an internal network and an external network at the same time with different set of information.

1. The problem
It is a typical problem in organizations that are growing that they have to resolve two problems at once:

• To have a DNS server for the internal network of the company because long ago there were already too many computers to remember their IP and even too many computers to maintain a set of host files

• To have a DNS server for the external servers, for external clients, etc.

• To solve this problems become a bigger problem when the growing organization can’t supply more resources than one DNS server3. It is a bigger problem because if you just configure your server with all your names, public and private, you’ll end up polluting the Internet with private addresses, something that is very bad, and also showing the world part of the topology of your internal network. Something you don’t want a possible attacker/cracker to have.

• The other part of the problem is that for efficiency you may want to resolve to internal IPs when you are inside and external IPs when you are outside. Here I am taking about computers which have public and private connections.
