Anonymous Coward writes: "Three Sixty Information Security have analysed 7 of their most frequently recommended tools for network and system administrators. Among the regulars like ssh and nmap are some tools less commonly known for their security admin credentials.

Finally it attempts to answer the question; "What makes this software so uncommonly good?""

Submission + - SPAM: IETF warns of potential Internet "train wreck

alphadogg writes: The IETF and ITU standards bodies are sparring over a set of next-generation network transport specifications that some say could lead to massive interoperability issues for service providers if left unchanged.``The situation is catastrophic,'' says Stewart Bryant, IETF liaison to the ITU-T on MPLS issues and a technical leader at Cisco. ``There's a fundamental opportunity for a major train wreck'' between the IETF's MPLS and the ITU-T's T-MPLS.

Submission + - 10 Plane Crashes That Changed Aviation (popularmechanics.com)

mattnyc99 writes: As horrifying (and voyeuristic) as they are, plane crashes have actually done a lot of good. There's only been one fatal crash in the U.S. in the past five years, and, in a follow-up to their safest seat on an airplane investigation, Popular Mechanics says that's because 10 accidents spurred new technology that keeps air travel safe and routine today.

Submission + - Do All Laptop Batteries Suck? 1

jon_anderson_ca writes: I have a Dell Inspiron 6400 with the (allegedly better-than-basic) 85 WHr battery. After a little over a year of using it, the battery is almost useless, and I'm not alone. Oh, and the battery's warranty is 12 months, of course.

My questions to Slashdot are: how do other laptop batteries fare these days? Do batteries last longer than 6-12 months on Apple, HP, even other Dell laptops? Is it just the Dell 85WHr 9-cell that's the problem? Why is it that battery life is so very short? Is there anything I can do about it (reconditioning or replacement)?

Submission + - How to keep laptop & desktop files in sync?

corinroyal writes: "I've setup Xubuntu & Lyx on my grandmother's old iBook G3 for my moderately luddite housemate who's writing her novel. I'd like her to be able to write on either her desktop or laptop and have any edits automagically synchronized with the other machine whenever the laptop is connected to our home network. I've looked a bit into options like Rsync, Unison, and the Coda distributed file system. Wondering if anyone here has found a good solution they'd care to describe. To my mind a great solution would have the following:
  1. Near real-time, continuous syncing when connected to the network
  2. Intelligent options for merging conflicting changes (such as when the same file has been edited on the disconnected laptop and on the desktop)
  3. Encrypted network traffic, compatibility with encrypted filesystems like truecrypt
  4. Invisible to user except in case of change conflicts
