    You make a good point.

    I got to wear an iPod mini at MacWorld, and it's hard to know just how small and light they are until you hold one yourself. They are SMALL and LIGHT. Maybe us geeks don't mind walking around batman-utility-belt style, but there are many people that would consider an original iPod to be way too huge that will now consider an iPod mini.

    I didn't think much of the arm strap though. Maybe it's just me, but it seemed to keep sliding around on me with just walking around. During a workout it seems like the band would slide a lot.

    Yeah, I see a lot of people stuck like that with insecure POP, and a lot of people who use the same password for their home account (which is almost always POP only) as they do for their work account. Bad bad bad.

    One thing you could do, if you want to be a bit more secure, is to port forward port 110 using SSH to a server at home. Your POP password is still going out in the clear then, but it's going in the clear from your house, which is presumably more secure that going out over open wireless.

    the tunnel would be something like this:

    ssh -L 110:www.yourhomeserver.com:110 -f -N yourname@www.yourhomeserver.com

    A funny aside:

    I was in Park City visiting friends over the holidays. The ISP for the friend that I was staying at went out of business, so I walked around the house looking for another wireless AP.

    At one corner of the house, I find one, and the name is the first initial and last name of the person running it. It's not running with any security so I'm able to hop onto the net. So, I feed in his first initial and last name and "park city" into google (on his own wireless, even) and google gives me his home address and phone number.

  4. POP passwords are the biggest risk I see out there on Risk Management of Wireless Networks · · Score: 4, Informative

    I've had some fun sniffing the network around the office, around town, and at O'Reilly OSXCon, and I think the biggest security risk I see on wireless networks are plaintext POP passwords going out in-the-clear.

    It's amazing how many people who should know better are still using plain POP for grabbing their mail. Since most mail client recheck for mail every few minutes, it's quite simple to grab passwords. Using those password, a hacker can then try the same password to enter the network, read the person's e-mail to do subsequent social engineering, or just fish around the person's e-mail for interesting information.

    The second thing I think most people don't realize is that on a standard wireless network all the HTTP url's they are surfing to with a web browser are public. This may not be a security risk, but companies also may not want a hacker in the parking lot to know that a server named secretinternaldata.mycompany.com exists.

    I set up an SSH tunnel from my laptop to my squid proxy at home just for fun to see if I could fix the issue. It worked well, but of course it's not something the average end-user with a laptop on wireless could manage.

    Anyway, that's my .02.

    Novell recommends that you take the courses that prepare you for the Linux Professional Institute Certification (LPIC) level 1 to obtain the baseline knowledge that will best ready you for the course on Novell Services.

    It appears the poster has confused this with the Novell Certified Linux Engineer study course, and his general impression is that he has some kind of anger at the lack of developement behind Novell's certification proposal.

    Huh? This story *is* about the Novell Certified Linux Engineer course and certification. I think you're the confused one. It clearly states in the FAQ on the Novell website that LPI certification and classes are not required for the class or the test, but they are recommended.

    You should check your facts before you call someone "wrong on so many levels." Again, my point is that Novell is calling someone a "Certified Linux Engineer" when all they are really testing the person on is their ability to install Novell's Linux-based products on Linux.

    I agree than some PHBs (or maybe Pointy Haired People Who Hire Consultants) are clueless when it comes to what certs are good and bad, I do thing that in the IT industry people generally know the quality certification from the low-quality ones. I think most people now know that there are a lot of Paper MCSEs and CNEs out there, and they don't look for just that cert when hiring a consultant.

    So, the problem with this certification from Novell is that it's called a Certified Linux Engineer, but it doesn't require any knowledge at all of the two Linux distributions that they now own. Also, this is really just one five-day class on a Novell product, not a whole certification track, so it kind of cheapens the entire value of the CxE certification for the whole CNE installed base.

    So, even as a door-opener, I think this cert is badly positioned.

    Novell had a Internet track to the CNE years ago, back in the days when Netscape Enterprise Web Server ran on Netware. The classes were horrible and I feel bad for anyone that paid to take them.

    It appears from the website that this is just a single 5-day course on Novell Nterprise Services for Linux (Netware File and Print and Directory Services running on Linux), not a course on SuSE or Ximian. They suggest (but do not require) that you get a LPI certification first before taking the class.

    It's kind of a stretch that they are calling this a Certified Linux Engineer, since there is no actual Linux training involved, just training on Novell's product running on Linux. In fact, the course material says that you should know Linux before taking the course.

    So, unfortunately this seems like yet another empty certification, and shame on Novell for calling someone a Certified Linux Engineer when all they did was take a 5-day course on one of Novell's Linux products.

    The server configuration feature is similar, but it isn't directly related to the DHCP security issue. The server configuration is specifically for cluster-type configurations where you want a server to boot up with a basic configuration automatically. You can also load the configuration from a file via a USB keychain or even an iPod. It's just a small XML file with all the configuration info.

    Theoretically a hacker could exploit this as a "security" hole, but they would need to set up a local LDAP server to give out the configuration, and they would need to reboot the Xserves. They could just as easily go up to the Xserve and reload the OS from CD.

    You can also purchase OSX Server and install it on a G4 or G5 tower, or heck, even an iMac. It's $999 for unlimited clients and $499 for 1-10 clients. The unlimited version is not limited in any way under samba or otherwise. Unlimited means unlimited.

    For support, you can purchase Applecare for the Xserve, which is basically a 3-year extended warranty, for $999. This doesn't cover configuration and installation. Frankly, OSX Server is easy enough to set up that I think a typical customer's best bet is to try to set it up themselves and then call support per-incident (I think $400 per incident).

    But, for large companies there is also a cool new program for direct tech-to-tech helpdesk support. This costs $2,799 and provides two contacts for calling Apple, plus a quarterly collection of software tools. It's a really good deal for large customers.

    • A large base of consultants to choose from
    • A good desktop and laptop solution. Does IBM support Linux on their laptops this week? Which models?
    • The ability to run Microsoft Office, Open Office, and most other open source productivity packages
    • The ability to centrally manage authentication and workstation management using OSX server


    The list goes on from there. A base model 17" eMac, which is perfectly suited to the average productivity worker, is only $799. Bump the RAM up to 256MB for a few dollars more and you're done, it will all work right out of the box.

Chess analogy or not, it's not exactly a postitive signal to be sending out to people doing your work for you. :)

    One very good point he makes is the idea of empowering other people to create materials about the technology you are evangelizing. It was amazing to me that I could get a lot of high quality help out of people for just a little public recognition, or some free software, or a nice gadget. People like to feel like they are helping with things that they feel passionately about. Heck, that's one of the reasons why the Linux movement has done so well, since just about anyone can dive in and start contributing in some way.

    The problem I always experienced was from internal groups who were afraid of losing control of the corporate image. For example, we talked a lot about providing open forums and community sites for end users and consultants to share their solutions. This ended up being a series of communities we called CoolSolutions. But the actual code and solutions that people wrote went through a gauntlet of legal and marketing people, and it really wasn't an "open" community, it was all carefully screened.

    The book "The Cluetrain Manifesto" talks a lot about these issues with large companies afraid to give up control. I think the right thing to do is for companies to loosly try to encourage an "ecosystem" around their technologies that then becomes self supporting. In this sense, they are practicing biomimicry in the form of crop diversity. You could think of internal PR and marketing departments as monocrops that are very susceptible to a single bad link, such as a sucky chief marketing officer. Diversity is good, and a product evangelism is one role that can encourage corporate "crop" diversity.

    The long-term solution is to just not have the data there. While it would be more work on the CPU to make the game engine instantly draw a character on-screen from no previous information, I would think most multiplayer gamers would give up a few FPS to play cheat-free.
