Guest Editor’s Note: On The Road Again

One of the coolest parts of being a Contributing Editor for
Linux Today is getting to occasionally write the weekly

For this editorial, I decided to write about my Linux and WiFi
adventures, from the road while on our family trip to Indiana. It
had been a few years since we were there and I was anxious to see
if it was any easier to stay connected while on a cross country
road trip vacation.

Since you probably don’t care about all the little family
things, I figured I’d share a few new portable computing
problem-solving tips that could save you some heartache while on a
similar jaunt. After all, Linux Today readers should enjoy their
vacations too. Being a geek shouldn’t create undue anxiety, just
because you can’t connect to the web or will be cooped up in a
minivan for 16 hours with three little kids.

Solving The Big Problem First

I had been fretting about setting up the new HP Pavilion
notebook so the kids could watch DVDs, while rolling through
Georgia, Tennessee, and Kentucky. Providing entertainment for the
kids, is an important problem to solve, before a cross country road

Xine filled the bill as a DVD player because my 10 year old
could easily control the program, with minimal instruction. It also
has a big volume control knob that could be adjusted while moving.
Out of the box SUSE (I use version 9.3 Pro) won’t play some DVDs,
so you’ll have to either get an enabled version of Xine or look up
how to run the locked movies.

Being a do-it-yourself kind of guy, I built a little shelf out
of 1/2 inch plywood, that was securely bungied to the front seat
arm rests. The rearward facing laptop sat on the part of the shelf
that projected toward the back seats. It too was securely bungied
to the shelf. This allowed for quick setup and takedown, because I
don’t like to leave the laptop in the van when we stop for bathroom
or meal breaks.

Electrical power for the laptop was supplied by a Vector 400-watt power inverter that
I bought at Home Depot. It was a bargain at around $40. It produces
a “modified sine wave” that worked fine with the HP Pavilion and my
cell phone charger.

The low voltage alarm sounded a few times when we first started
the laptop, but after a couple of minutes everything settled down
and worked great. The Vector easily handled the laptop’s power
requirements and never even got warm. I simply stuffed it under the
front seat and plugged it into a nearby 12-volt outlet.

Solving Dynamic Problems

In typical geek fashion, I originally chose to solve computing
problems as they came along. When my common sense returned, the day
before we left, I scurried around collecting the little odds and
ends that I might need, to solve my “dynamic” problems. They

  • A 6-foot long roll-up CAT 5 cable
  • A 6-foot phone cord
  • SMC 802.11b Barricade router
  • Wall worts for the cell phone, Gyromouse, router, and iPAQ
  • SUSE 9.3 Linux Pro DVDs
  • 12-foot extension cord

All these things packed easily into my day backpack, along with
my iPAQ and a few folders. The laptop went in a different bag,
along with it’s power supply brick and cord. The laptop’s power
cord is easily forgotten in the heat of packing, so it’s best to
double check that you have it.

The reason I packed the router was that I knew that my various
in-laws had broadband and I might need to provide my own connection
from the cable/DSL modem back. Yes I’m spoiled with broadband and

As it turned out, I was unable to use the WiFi connection at my
sister-in-law’s house in Indianapolis. I hadn’t fiddled around with
WEP on the new Pavilion and didn’t have time to troubleshoot. The
simple solution was to plug my CAT5 cable into the back of her
router and use the wired connection.

Later, I fired up my SMC router and worked out the kinks in my
encryption configuration. Making WEP work with the Broadcom chip in
the Pavilion turned out to be a no-brainer, by adding the
encryption key and 128-bit key length values in the
/etc/sysconfig/network/ifcfg-wlan0 file.

I was under the gun to work out the WEP connection details
because I was slated to man the Linux Today site, while Managing
Editor Brian Proffitt got a little R&R on Thursday and

I had arranged to use my brother-in-law’s broadband connection
in Evansville, but found out that he didn’t have the passphrase
string for his WEP installation. Having my own (working) wireless
router made the solution as simple as replacing routers at the
cable/dsl modem and connecting to the net. When finished I could
just plug his router back in and everything would be back to
normal. So, the end-of-the-week Linux news is brought to you

Finding Things

I’m happy to report that it’s getting easier to stay connected
while on the road.

For example, in spite of getting to Macon, Georgia at 10 PM, we
were still able to find a Comfort Inn with free WiFi. Everybody got
settled in and I was able to check email and cruise news sites from
my room.

I’ve come to really depend on my little WiFi enabled iPAQ to
sniff out available access points. Sure beats dragging out the
laptop, getting it all running and then finding out that there
aren’t any in the area.

These days you’re likely to find access points in a lot of
interesting places.

During an iced tea and ice cream stop at a Dairy Queen in
Elizabethtown, Kentucky, the iPAQ picked up an access point right
there in the story. Sure enough, I was able to cruise the Web for a
few minutes, while the kids cooled off.

Sadly, I wasn’t able to find any WiFi hotspots at Holiday World in Santa Claus,
Indiana. Coming from the land of Disney (Orlando) I really expected
to find a few at this top notch theme park. In spite of the lack of
connectivity, I am happy to report that Holiday World is a great
place to take your family. It has to be the cleanest park I’ve ever
seen. System admins will appreciate the organization and attention
to details. Make sure to pack your swimsuit and towels, because the
water park is a truly great time, especially with your kids. They
also thoughtfully provide wagons to carry around all your gear, for
a few bucks. The roller coasters were thrilling as well.

Speaking of roller coasters, I spotted a Red Hat Linux emblem on
a backpack in a wagon parked near the Legend, at about 4 PM on
Wednesday, July 19th. Now whenever I see a Linux insignia in an
amusement park, I try to wait around for the owner, so we can talk
Open Source. I eventually had to move on. Sorry I missed you, drop
me an email, if you get the chance.

No doubt the Linux-oriented backpack’s owner and his/her family
were having as good a time on vacation as we were.

That’s it from the road.
