re #191
Car door locks are also trivial but they deter most that may be tempted.
Defense in depth starts with simple security. Why would you not recommend
a simple configuration? Does jep live in Fort Knox or something?

Re #189: also choose a more cryptic SSID and create a closed network (so that
the SSID is not brodcast to any passing computer). I keep hearing different
opinions about the security of WEP - if the password is changed now and then
I thought it was pretty secure.

re #193
The neighbors were leeching bandwidth off my wireless router for several
months before I realized it. When I put the clamps down on the WEP setup then
there was a noticable difference in performance. Normally, I SSH for most
of my online transactions but for the layman I'd recommend securing your
entrypoint to the router.

Re resp:191: It's "trivial" in the sense that it's been automated, but
cracking WEP requires capturing a significant amount of traffic.
Unless jep has a lot of network traffic going on, someone's going to
have to capture data for several days before they'll stand a good
chance of cracking his key. (And of course they'll be foiled if he
changes his key during that time.)
WEP isn't secure in the sense computer professionals use the word
"secure," but it does act as a deterrent to casual leechers and
eavesdroppers.

WEP - Windows Entertainment Pack?
We don't have a router or ADSL modem. How much power would a computer draw
with the monitor turned off and hard drive powered down?
There would be no loss of service to an ISP if someone who would not buy
broadband service borrowed a very small fraction of it. The phone company
used to consider it illegal to have your own phone instead of renting a phone
from them, or to have extension phones when it became legal to own your own
phone, not that it cost them anything. People would turn off the ringers on
the extension phones so the company would not know about them.

WTF? You said in #182 that you have a router, now you say you don't
have one?
Using someone else's broadband to check your email once a week would be
using a "very small fraction" of the service. Using it to stream music
for three and a half hours a day is not a "very small fraction."

You need both a router and some sort of network card.
You don't usually get to pick and choose the number of connections your router
can support other than by selecting one model over another. Just because your
router supports 32/64/a gazillion connections doesn't mean you have to use
them all.

We are not planning to use the router, just the wireless card, to learn how
to use a wireless card, and play 32K streaming audio, which is a very small
fraction of 1500K DSL line. Jim's 'ISP' connection is simply too
unpredictable to listen to music with - anywhere from 5K to 0K/sec downloads
and you get bumped off whenever they feel like it. 3/150 is about 2%.
We succeeded in getting the digital piano to play through headphones (phone
jack) and through the receiver (AUX out), and (badly) from the tape deck into
the piano (AUX in) and recorded my playing directly to the tape deck. The
AUX in has a great deal of static. Jim says we won't need radio now, we can
just record all the great piano music after getting free sheetmusic downloads.
He also plugged into the headphone jack a little gadget that broadcasts FM
to the nearest receiver, and it sounded awful but recognizable.
Does anyone know how to construct the cable that plugs into the round MIDI
jack at the back and then into the sound card MIDI (game port) port (or does
it plug into line out?)? I will look online for the wiring diagram. I want
to try playing piano midi music on the piano from the sound card.
Who needs broadband to check email when there is grex?

Re #192: I don't know jep's circumstances but I'm about to
deploy two wireless LANs, one of which will be at home. I
don't have anything top secret, but would still prefer to
keep my information private unless I explicitly publish it
for some reason. I have heard that WPA is less insecure
than WEP, but I'm thinking of going further by using
additional software to encrypt everything that gets sent
over the wireless LAN.
Re #195: My wireless LAN will see a significant amount of
traffic.
Re #196: I have a computer with a good power supply that
burns 27 Watts most of the time it's switched on. Other
machines may require more power.
Re #199: This is a guess, but it's
worth a try. Please let me know PC MIDI
if it works, so that I can add it ~~~~~~ ~~~~~~
to my notes. Use sheilded cable 4 GND ---- RX- 5
and connect the shield to pin 2 12 TXD ---> RX+ 4
on the MIDI connector. Leave the
shield unconnected at the PC end.

I do not rely on WEP or WPA for my wireless. Any encryption I need is
performed in different layers.

Could you explain to me what RX means? Do we need only two wires connected?
The midi port looks like a keyboard plug.
Linksys (who made our wireless card) says they only support Windows. Realtek
(who made the chip on it) has a lot of broken links to Mac and Linux (source
code) drivers. Someone else posted an alpha version of a driver for this
chip, source code, which requires that I have kernel source code for 2.4 or
2.6, which I need to get and unpack into about 100MB on my computer in order
to be able to compile one little module (102K for Windows, by Realtek). Is
there some way to compile a module without the entire kernel source code?
Can I read the Makefile and just put in the parts it needs?

RX usually means 'receive'. TX is usually 'transmit'.

re 202: most drivers can be built outside the kernel tree, but you might need
at least the kernel headers installed - depending on the disrto, you might
require the kernel-devel package or equivalent.

Slackware. So I install just the kernel headers for 2.4.31 and then do a
'make'? I followed a link at the URL cited for cryogenics and found the
schematics for the SB $50 MIDI cable, which requires 1 diode, 2 resistors,
an OptoIsolator and an IC (with transistors in them) and a plug ends for
gameport, MIDI IN and MIDI OUT (5 pin) which we might have around but not the
IC and OptoIsolator. I wonder if this would let me also record MIDI files
to the computer (from MIDI out) with the right software.

For any compilation it's supposed to be the headers for the kernel libc was
compiled under, and for compiling kernel modules I'm pretty sure it has to
match the kernel you'll be trying to use the module under.

I'm not familiar w/ slack, haven't touched it in a dozen years at least, but
I'd expect to unpack my driver source somewhere and be able to run
make in the directory, maybe with a configure first (that might show some
library dependency), unless it's one of those rare ones that actually use bits
of ones existing in the kernel tree, then you'd need the lot.
If my memory serves me correctly the MIDI interface use a current loop, hence
the need for couplers, and is a serial interface, with one transmit loop (TX)
and one to receive (RX).

The INSTALL file said to just 'make', not make config or configure. Do the
kernel headers come with a .config file or would I need to get hold of the
one used to compile the 2.4 kernel I will use with this module and copy that
to /build along with kernel headers?

My circumstances are that I have a wireless network with 3 (soon to be
4) computers sharing cable modem service. I use the Internet a fair
amount and so do the kids, for e-mail, music downloads, games, on-line
banking, chat, random browsing and homework. If I need WEP, I guess
I'll figure out what it is and how to install it or turn it on. If I
need more than that, please someone let me know. I will appreciate it
very much!

I installed kernel-headers and they did not go into /lib/modules/2.4.31/build,
where .config was supposed to show up, so I also apparently need kernel source
code, or at least the .config file from it. In addition, the 2.4.31 kernel
headers overwrite the ones in /usr/src/linux-2.2.16/include/linux (because
of the way the symlinks are set up, because they installed into
/usr/include/linux, which is symlinked to
/usr/src/linux-2.2.16/include/linux). Will this be a problem if I want to
compile another 2.2.16 kernel some time? They are dated 1998-2005 and have
no mention of the kernel version, so maybe they are just updates that will
also work with older versions.
I need to get hold of the 37MB of source code now.

/lib/modules/<kernel-version>/build, if it exists, should be a symlink to
/usr/src/linux-<version>. Did you look there?

There is no such symlink on my computer, should I make one? I now have 2.4.31
kernel headers in the 2.2.16 directory. Should I rename it, and then
reinstall 2.2.16, and make the symlink? I tried making the symlink and since
I don't have kernel source on this computer yet there is no .config file.
It would be easier to get an older wireless card from ebay than to get this
stupid WIndows one to work with linux.

Do you have an extra one you want to give us? It is against our rules to buy
anything we can get for free. Jim is going to modify keyboard plugs to make
180 degree 5-pin DINs and maybe chop the 15-pin DB off a joystick. First he
has to remove the rubber outer part of a roller to try to make a subpad out
of it for a laser printer that feeds all the sheets at once. THe official
replacement costs $10.50 plus shipping. In the meantime he has had it apart
a few times to clean it, and I feed one page at a time. And someone returned
a working laser printer we lent them in 2001.
