Submission + - Should Cities Install Moving Sidewalks?

Submitted by theodp
theodp writes: 'The real problem nowadays is how to move crowds,' said the manager of the failed Trottoir Roulant Rapide high-speed (9 km/h) people mover project. 'They can travel fast over long distances with the TGV (high-speed train) or airplanes, but not over short distances (under 1 km).' Slate's Tom Vanderbilt explores whether moving walkways might be viable for urban transportation. The first moving sidewalks were unveiled at Chicago's 1893 Columbian Exposition, and at one point seemed destined to supplant some subways, but never took root in cities for a variety of reasons. Vanderbilt turns to science fiction for inspiration, where 30 mph walkways put today's tortoise-like speed ranges of .5-.83 m/s to shame. In the meantime, Jerry Seinfeld will just have to learn to live with 'the people who get onto the moving walkway and just stand there. Like it's a ride.'

  • Fairly standard nmap usage kills un(der)configured, unpatched gear? Hmmm, is this news?
  • The only detail in the main thread is a mail from someone off list forwarded by a member, and it paints a rather broad and elusive picture.

Onderw.: Should nmap cause a DoS on cisco routers?

Hello,

Some days ago, I had the task to discover the SNMP version that our
servers and networking devices use. So I run nmap using the following
command:

nmap -sU -sV -p 161-162 -iL target_file.txt

This command was supposed to use UDP to probe ports 161 and 162, which
are used for SNMP and SNMP Trap respectively, and return the SNMP
version.

This "innocent" command caused most networking devices to crash and
reboot, causing a Denial of Service attack and bringing down the
network.

Now my question is.. Should this had happened? Can nmap bring the whole
network down from one single machine?

Is this a configuration error of the networking devices?

This is scary...

What can be done with that secret ID? Quite a lot, it turns out. The IMSI is sent by the phone to the network when first signing on to the network; it's used by the network to figure out which call should be routed where. With someone else's IMSI, an attacker can determine the person's name and phone number, and even track his or her position. It also opens the door to active attacks—creating fake cell towers that a victim's phone will connect to, enabling every call and text message to be eavesdropped.
