That is on a 1U 48 10G + 4 40G uplink switch. The 4 40G ports are broken out into 16 10G ports using QSPF+ to 4x SPF+ cables, so it is in effect a 64 port 10G switch.

eth0 is the 1G management port, it is connected only to the CPU. swp1-swp48 are the native 10G ports, and swp49s0-swp52s3 are the broken out 40G ports. You can choose to combine 4x 10G ports into a 40G port, or break 40G ports into 10G in nearly any combination you need.

ifconfig would work as well, but is a lot more verbose.

It is open source, except for a userspace device driver for the forwarding ASIC. Without the driver, everything works the same, you just don't get hardware accelerated forwarding, only the normal kernel softward forwarding.

You can get the patches against Debian Wheezy here:
http://oss.cumulusnetworks.com/

The biggest difference vs EOS is that if you want to add a route to the routing table in EOS, you have to use sysdb-specific commands/APIs. With Cumulus Linux, you use "ip route add" or any other program that knows how to add routes to the Linux kernel using netlink or legacy methods. Same with ACLs, EOS has proprietary commands/APIs, Cumulus Linux uses iptables.

Also, A random Linux program will install and work fine on Cumulus Linux, whereas it usually takes a (small, but real) amount of work to make that happen on EOS. I've even installed and run Firefox from the Debian repo onto a switch, and it worked fine.

The big difference is that there is a hardware forwarding chip involved. A PC with 10G NICs is hard pressed to forward at 80 Gbit/sec, and draws a couple hundred watts. The 1U switches Dinesh is talking about can do 1.28 Tbit/sec with all features enabled, and draw around 100 watts.

WPA-PSK Cracking As a Service 175

Posted by kdawson on Monday December 07, 2009 @08:31PM from the get-out-of-the-cafe-quicker dept.

An anonymous reader writes "Moxie Marlinspike, a security researcher well known for his SSL/TLS attacks, today launched a cloud-based WPA cracking service, where for $34 you can test the security of your WPA password. The WPA Cracker Web site states: 'WPA-PSK networks are vulnerable to dictionary attacks, but running a respectable-sized dictionary over a WPA network handshake can take days or weeks. WPA Cracker gives you access to a 400CPU cluster that will run your network capture against a 135 million word dictionary created specifically for WPA passwords. While this job would take over 5 days on a contemporary dual-core PC, on our cluster it takes an average of 20 minutes.'"

Nerds Switching from Apple to Ubuntu? 957

Posted by timothy on Monday July 03, 2006 @05:28PM from the different-bell-curve-entirely dept.

Mindpicnic writes "The recent switch of two lifelong Mac nerds to Ubuntu hasn't escaped Tim O'Reilly's radar. He cites Jason Kottke: 'If I were Apple, I'd be worried about this. Two lifelong Mac fans are switching away from Macs to PCs running Ubuntu Linux: first it was Mark Pilgrim and now Cory Doctorow. Nerds are a small demographic, but they can also be the canary in the coal mine with stuff like this.'"

Billions Donated to Charity 1245

Anonymous Philanthropist writes " Warren Buffet , the world's second-richest man, announced over the weekend that he will soon donate 85% of his entire net worth, weighing in at around $37 Billion, to charities, with over 80% of it going to the Bill and Melinda Gates Foundation. This makes it the single largest monetary donation in history."

Try dropping down one of the menus in windbg. Don't select one, just leave the menu up. 100% CPU.

It gets even better; windbg runs with elevated priority, so if you try this in a normal priority VNC server, it is time to call and have someone move the mouse for you on the physical machine.
