UK Trains Take WiFi Route To Connectivity
Randy Sparks writes "The BBC is reporting that one of the UK's largest train operators, GNER, is to offer Wi-Fi net access on its trains. What's interesting is how this net connection will be achieved - by a combination of networks provided by multiple mobile phone connections or even digital TV Internet, provided from ground stations the train passes by.

EXPERTS IN "computer security" have worked out a simple way to knock out any email server.
A team at NGS Software said that the trick involves sending forged emails that contain thousands of incorrect addresses in the "copy to" fields.
When this package is sent, huge quantities of unwanted email will be sent to another mail server.
All it takes is finding a server configured to return an email with attachments to each incorrect address. Next you have to forge an email so it appears to come from the mail server that is to be the target.
When the forged email, complete with the thousands of incorrect addresses is sent, an avalanche of "bounced" messages sent to the target server causes it to crash.
According to New Scientist, with one little 10K email, hackers could then send 100MB back to a server.
A third of the email servers of all Fortune 500 companies are, it appears, open to this kind of attack. If the hacker used an insecure email server the attack would be virtually untraceable.
