Not all of us can use outside mail browsers. I could not use the one on
the NTLUG website, but had to copy my comments to Outlook, because of
restrictions on our company server. No response yet on my Linux
installation question below.

I'm having some trouble setting up a laptop for a wireless connection.
I'm using Fedora Core 6 and a Netgear PCMCIA card. I got the drivers
installed and working. I am also aboe to detect other networks. The
problem I am having is with the WEP key. For some reason it doesn't
seem like it is transmitting the WEP key which causes my router to not
assign a valid IP address. All of the other PCs work and can get a
valid IP address from the router so I know that the WEP key is not being
typed in incorrectly.
Any ideas on how to get this working?
Also I am using the madwifi drivers for my PCMCIA card.

See if it works manually.
iwconfig wlan0 key yourwepkey
iwconfig wlan0 mode Managed
iwconfig wlan0 key restricted
Use the correct interface for your setup.

I would like to install a good usable version of Linux on a USB hard
drive for my company Dell D610 laptop, so I can safely sort and organize
files on my NTFS file system and also have a computer that I can use to
do presentations in Open Office without all the Windows XP bugs,
interruptions, etc. Can any of you recommend a distro that:
1. Installs cleanly?
2. Graphics display properly?
3. Reads NTFS file system?
I will be at the November NTLUG meeting at 0900 and would like some
assistance in installing. Any advice in the meantime would be much
appreciated.

I would like to press this one a little bit...
I also am an embedded developer. At work, I use 8051 microcontrollers (8
bit) exclusively. My main experience is with the Keil uVision IDE and
the MPLAB IDE for PIC processors. As a Linux user, I know that there
are a load of good IDE choices out there for writing and debugging any
language you would like, so naturally I wanted to use some of those
tools in my embedded development work.
After much digging I realized that there are few "natural fits" in the
IDE world for 8-16 bit embedded developers because of the need to debug
code on remote targets. All of the "IDEs" out there will let you
compile and fix syntax errors, but when it comes to debugging, you have
a harder battle. GDB, and thus DDD, are generally pointed to at the
solution, but what is assumed is that you know how to interface GDB with
your hardware. That is a big assumption.
In my limited experience, all USB debugging hardware is not supported
outside of windows. If your device has true JTAG support, you can get
into the realm of "wigglers" and other JTAG debugging hardware through a
parallel port. If you need a true In Circuit Emulator (ICE), you have to
debug on windows or do without true debugging (i.e. rely on toggling
extra I/O pins or sending messages to an LCD or serial port to tell you
what is happening inside the code).
Some people get really creative and somehow involve windows PC with
specific windows only hardware and interface that to gdb using TCP/IP or
something like that. As far as solutions go, that won't cut it. It is a
clunky, patchwork replacement to true integrated tools that work in
windows.
Last year, I went to the Silicon Valley Embedded Conference and asked
everyone out there from chip manufactures to third party tool vendors
about linux tools for programming 8-16 bit micros. No one knew of
anything that might be a Linux solution to such environments as Keil and
IAR offer. I even talked with people from the Eclipse Foundation, and
they recognized that hardware debugging was a missing component of
Eclipse and that someone was "looking in to". I found all of this a
little funny considering there was so much emphasis on Linux that year
in the higher embedded spaces 64 bit RTOS from companies like Windriver
and Greenhill.
At this point, I would like to hear from all of the embedded developers
on the list. What targets do you develop for, in Linux, and what tools
do you use to get to that target?

P.S. Sorry about the novel.

I have a problem with soft links and nfs mounts. I know the problem, I
just can't find a way around it.
I have two servers, one is the main Samba file server (Server02), the
other is a server that is part of another system (SysServ). I have a
folder on SysServ that is shared between system workstations and office
workstations. The file is /home/system/traffic_import. On system
workstations, I have in fstab:
SysServ:/home/system/traffic_import /home/system/traffic_import nfs
defaults 0 0
These are all Linux workstations and everything works fine.
On Server02, fstab contains:
SysServ:/home/system/traffic_import
/shares/snat/Departments/TRAFFIC/traffic_import nfs defaults 0 0
Also on the System02 server in the /shares folder is a softlink:
TRAFFIC -> /shares/snat/Departments/TRAFFIC
When the appropriate users log in, they are mapped to /shares/TRAFFIC
Here's the problem. If I go into (ssh) Server02 as a user and do 'll
/shares/snat/Departments/TRAFFIC/traffic_import' I can see the files in
the folder that is on SysServ. However, a network user logging into the
system can see all the files on TRAFFIC, but when they go into
TRAFFIC\traffic_import, they do not see the files on SysServ, but the
files that were in the traffic_import folder native on Server02.
So, how do I get users to see the mounted folder traffic_import?
Thanks for any ideas.
Michael
