Subject: [U-Boot-Users] U-Boot not responding back to ARP requests?
Date: Sun, 26 Sep 2004 13:29:09 -0700	[thread overview]
Message-ID: <6.1.1.1.0.20040926124409.01e178d0@wheresmymailserver.com> (raw)

All:

I was doing some debugging of some networking issues I am seeing, and saw
something that I thought was strange. I am seeing the following:

If I set things up as U-Boot = 192.168.0.3 and cross over cable to U-boot 
on 192.168.0.2

 From U-boot, if I ping 192.168.0.2

The ethereal dump is something like:

U-Boot Broadcasts -> Who has 192.168.0.2? Tell 192.168.0.3
Server Reply      -> I do (192.168.0.3 is at aa.bb.cc.dd.ff.gg)
U-boot IMCP       -> ping request
Server IMCP       -> ping reply

And now U-boot stops, and goes back to the command prompt. (like it should)

Now the Server starts asking:

Server Broadcasts -> who has 192.168.0.3? Tell 192.168.0.2
Server Broadcasts -> who has 192.168.0.3? Tell 192.168.0.2
Server Broadcasts -> who has 192.168.0.3? Tell 192.168.0.2
It does that three times (once a second) every time that it sees a packet.

My question is - shouldn't U-Boot respond? I don't see it in the code (I 
see the rarp handler, but not a arp handler).

My problem is that I have many U-boot boards on the same network, and the 
network is being flooded with ARP traffic, as the routers try to figure out 
the U-Boot MAC<->IP associations.

Thanks
-Robin
