get/set ifconfig entries through by programmatically

Is it possible to get/set  ifconfig entries through by programmatically. 
If yes, please send me the code snippet ...

I am trying to get/set ipaddress by executing the command "ifconfig" .

To get the addresses, use the ifconfig-in-a-box interface
getifaddrs(3).  To set the address, you'll need to use the functions
described in networking(4), specifically the SIOCAIFADDR and
SIOCDIFADDR ioctls.

JTAG recommendations?

Hi,

Since I recently got a new notebook without a parallel port I can no
longer use my old parallel port based JTAG cable.

I searched the web for USB based JTAG cables with open source drivers,
but there aren't many of those available, it seems. The best match
seems to be the JTAGkey/JTAGkey-Tiny from Amontec [1] - a solution
based on the FTDI FT2232L USB UART IC (but I think these cables are
somewhat expensive compared to their complexity).

However, this leads on to the next problem. My old parallel port cable
is supported by the devel/jtag port from the openwince [2]
project. However, this software is quite a mess. It hasn't seen a
release since late 2003, new features are available as a mix of 3rd
party and upstream CVS patches, and it doesn't support any USB based
JTAG cables.

The JTAG software found in the OpenOCD [3] project, however, seems to
support USB based JTAG cables such as the JTAGkey - but it isn't in
ports yet, so I guess this is not what other FreeBSD developers/users
use?

My question - before I choose to either bite the apple and buy a
JTAGkey or construct my own USB JTAG cable - is: what do you
guys'n'gals use for your everyday JTAG needs? Which cable? Which
software?

I can't be the only one in need of an modern, open source friendly
JTAG solution :)

If you could compile software manually and test it, I can help you with 
creating a port. Not sure I am the best person to do it, but I could help a 
bit.

Thanks, but that's not the problem - I know how to create a
port.

That's not the issue here - I was asking what other people on FreeBSD
use for their JTAG needs, seeing that OpenOCD isn't in ports I doubt
that is in widespread use among FreeBSD users (else, someone would
have submitted a port).

See http://www.macraigor.com/wiggler.htm - it's the de facto standard
when it comes to parallel port JTAG connections. It is supported by
both openwince-jtag and OpenOCD.

I use it for downloading new firmware images to devices and debugging
said firmware.

Embedded systems protection?


Hello All,

I am looking for ideas how an embedded system can be secured against
copying ...

One way that is popular is to use a OTP flash with a cert inside that
you verify to see if something has changed.

Otherwise certs in different ways is the approach.

How will that protect from copying? The contents of the flash can
still be read.

One solution, which I have used earlier, is to have a small bootloader
in internal flash which then loads, verifies and decrypts the main
application (which has been encrypted) from external flash. The key
point here is to make sure the internal flash can not be read out by
any means.

Brix
