How to use DHCP client in u-boot

First of all you have to program u-boot  with DHCP/BOOTP client (see
attached file)

tftpboot a0800000 u-boot.bin
protect off 1:96-97
erase 1:96-97
cp.b  a0800000 bfc60000 30210

Reboot the card to make sure that u-boot works

Configure the card according to this

nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=
$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=
$consoledev,$bau
drate $othbootargs;tftp $loadaddr $bootfile;bootm $loadaddr\

bootdelay=5

baudrate=9600

netdev=eth0

consoledev=ttyS0

cardtype=RDGR

modetty0=9600n8

ethact=EMAC0_MII

ethaddr=00:50:c2:59:30:48:49

host=Lotus_179

hostname=Lotus_179

bootcmd=setenv bootargs root=/dev/mtdblock0 rw rootfstype=jffs2 ip=
${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:eth0:off
mtdparts=phys_mapped_f
lash:12M(root),-(ROM)ro; dhcp; bootm bfc60000

autoload=no

dhcp_boot=dhcp

bootfile=uImage

gatewayip=192.168.1.55

netmask=255.255.255.0

serverip=192.168.1.168

stdin=serial

stdout=serial

stderr=serial

uimage=tftpboot a0800000 uImage ; erase 1:99-127 ; cp.b a0800000
bfc60000 ${filesize}

Important things to pay attention to:
- bootcmd starts from running DHCP client and setting environment
variable bootargs
- there is no environment variables ipaddr and bootargs
- two variables added  autoload=no and dhcp_boot=dhcp
- command 'run uimage' will program the kernel to the FLASH

To set variable bootcmd you can use command like this (pay attention to
the escaping '')

setenv bootcmd 'dhcp;  setenv bootargs root=/dev/mtdblock0 rw
rootfstype=jffs2 ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:
${hostname}:eth0:off mtdparts=phys_mapped_flash:12M(root),-(ROM)ro;
bootm bfc60000

NAT presentation I prepared recently

Buying EST WindRiver VisionClick ?

Every Tornado costs about what EJTAG+VisionCLICK and JTAG debugging is more reliable. if you are not looking for task level breakpoints and ready to use Windows for debug may be JTAG is a way to go.

Let me repeat again - in case of Wind River System higher price does NOT buy better product. Choose products carefully, compare alternatives.

Apparently WindRiver stopped (Dec 2006 ?) to support VisionClick and pushes WorkBench. The environment is Eclipse based and relatively slow, but the major problem - it costs money and licensed and protected with keys and requires e-mails to unlock and so on. Now the new probe with USB - prepare RedHat/SuSE Linux. Debian is not an option. WindRiver decided to use proprietary USB driver (Jungo ?) instead of standard open source libUSB. Jungo may be is a great company and may be their products are excellent, but unfortunately I can not compile the driver, because the driver is closed source. WindRiver could define HDI or work in simple bulk mode and use libUSB.

Quick tip. This is suprisingly difficult to find good (or reasonably good) terminal emulation client able to connect to serial port. there are some freeware and shareware, but they are extremely annoying in asking money. I suggest to look for VaraTerm for Windows (Linux has not these problems - minimcom does the job just fine).

Another quick tip is related to the UART driver for vxWorks and Shell. Implement ioctrl function with something returning OKs and ENOSYS. Do not skip this function. Do not try to return OK or ERROR in all cases. vxWorks Shell will display 'unknown command' every time you press a key.

To Shaw Fiberlink users:

Try one of alternatives

• Start download multiple dummy torrents. Configure your BT client to use 1kB/s of upstream and 1kb/s of downstream and up to 2000 connections for every one of these dummy downloads.
• Run SYN port scan using port scan tool like NMAP from http://www.insecure.org/nmap/ for some well known and reliable WEB server like Google or Yahoo.

Explanation. Traffic shaper keeps/records all existing TCP connections or 'flows'. Because performance of the box is expected to be high they probably use special kind memory like CAM. It is very fast but has limited size. Let check how reliable the box is. I suggest to create multiple dummy TCP connections and run them in the background. You can call it stress test. Every desktop can create about 60K connections simultaneously. i think that reasonable number of connections somewhere on the order of 2-10K. Important ! Every connection costs may be 32-64K RAM depending on OS and TCP/IP stack settings. In case of Windows you will need 512M RAM at least to run such number of connections without signifcant performance degradation. Also make sure that you are not behind NAT - your IP address returned by ipconfig command is the same as one you see here http://www.broadbandreports.com/whois
Average CMTS supports between 20-100K of modems. If 10% of modems establish 2000 conenctions each we are talking about 10M connections. If single record size is 16 bytes we have 160MB data base. There is no way to store it in CAM memory.
If Ellacoya equipment attempts to terminate TCP connection (or PROXY the TCP session) the most painfull for this device is going to be establish of TCP session. My wild guess that they can handle no more than 200K connections/s. It means that for 50K users CMTS we have to establish (and immediately close) 5 TCP connections/s for every one of 50K IP addresses to bring the system down.
Pay attention that depending on CMTS it can bring down the gateway (router) too, but i think that probability is low - packet forwarding is much simpler task than traffic shaping.

Another interesting comment can be found here http://www.internet2.edu/~shalunov/netkill/netkill.html
The idea is to establish TCP connection and let it to run forever. More details on how load balancing systems are affected.

From Ellacoya website
The traditional approach to traffic classification on IP networks associates an application with a TCP or UDP port number. For example, HTTP uses port 80 and FTP uses port 21. But this approach fails with peer-to-peer traffic because as much as 60% of peer-to-peer traffic appears on random port numbers. This behavior is commonly known as port-hopping. To accomplish this, however, the peers need to understand what real payload is. For example, if the peer-to-peer desktop application randomly decides to have the traffic appear as HTTP, or web traffic, the other peer needs to understand the incoming traffic is actually peer-to-peer traffic and not web traffic. It's similar to the way in which encryption systems work - both ends need to understand how to decode the message. The peer-to-peer designers accomplish this by the use of 'signatures' embedded in the data packet. So, if one knows what the signature looks like and can look inside each data packet traversing the network, one can identify peer-to-peer traffic that are pretending to be something else.
Weak encryption like XOR with key unique for every file (it can be, for example hash of the file) will bring this system to the knees. Such traffic shaper can do absolutely nothing with encrypted data. Actually it can not even recognize that the data is encrypted.
Talking about multiplayer games you guys gave me great idea, thank you.
I understand that you read this website. I think that we could discuss the problem of trafic shaping in the modern networks openly on this website message board. I think that the problem is significantly more complicated than many beleive. It does not mean that there is no solution - there is, but it is not apparent.

From Ellacoya website
In many instances, reducing the amount of bandwidth consumes by peer-to-peer applications can result an additional 25% of the subscribers added to the network without the need for additional CMTS, node splits or other HFC capital investments.
25% is considered to be dramatic impovement ? and what about VoIP, VoD, etc. ? In many applications the traffic is symmetrical, including e-mail. What about personal WEB servers ? In my opinion ISPs have to solve the problem using rational approach.

From Ellacoya website
With the ability to detect and prioritize VoIP applications by subscriber and service provider, the broadband service provider can choose a service delivery model that best suits its needs. For example, once traf.c from a non-facilities based voice service provider is identi.ed, the provider could strike an agreement with the service provider to prioritize its traf.c, or market QoS to the subscriber directly for service enhancement. A large provider rolling out its own VoIP service might guarantee QoS for its service, while leaving all other VoIP traf.c untouched as currently done today.
Does it mean that SBC and Skype will deliver different voice quality ? Do ISPs (broadband service providers) agreements with their customers mention 'service delivery models' for different service providers. Actually it is very easy to prove that ISP does use traffic shaper. Take any two nodes behind the same default gateway and run different applications on them.
