Hi,
I was just wondering in using TAP with the HTTP server (and following the instructions in the genode 10.02 documentation), i've noticed that when i have multiple connections to the server, whereby i have a windows xp virtual machine making requests to the server in addition to the host operating system (the XP vm is running in qemu as well as the web server), the IP addresses that the web server obtains are always the same regardless of the machine making the requests. Does anyone know how to provide unique IP addresses for each VM ie. is there an option i can/need to specify when i run qemu? or is there something i have to do with dhcpd3 or the conf,pid or lease files to ensure this functionality.
Thanks Peter
Hi Peter, I'm not sure if I've got your setup right or not. You have a host operating system (guess linux) with two qemu instances, one running Windows XP and the other running genode with the webserver. Your host system also runs a dhcp server which assigns the same ip address to both qemu instances. This assignment could be caused by the fact that both qemu instances have the same mac address. The 10.02 release notes state that the nic driver "fakes an ethernet NIC with the MAC address 02-00-00-00-00-01". Where could that MAC address come from? The driver obtains it from qemu in dde_tx_handler: dde_linux26_net_get_mac_addr(1, (unsigned char*)_mac_addr.addr); This schould be exactly that MAC address you shoud have configured when starting up qemu (did you?): This could look like "-net nic,model=pcnet,macaddr=00:81:71:61:51:41" Perhaps you forgot this step? If you haven't, it would be helpful if you provided a Wireshark trace taken from your tap interface. Cheers Sven

Hi Sven,
I'm not sure if I've got your setup right or not.
You have a host operating system (guess linux) with two qemu instances, one running Windows XP and the other running genode with the webserver.
Your host system also runs a dhcp server which assigns the same ip address to both qemu instances.
I have this exact setup, where the host operating system is Ubuntu.
This assignment could be caused by the fact that both qemu instances have the same mac address.
The 10.02 release notes state that the nic driver "fakes an ethernet NIC with the MAC address 02-00-00-00-00-01". Where could that MAC address come from? The driver obtains it from qemu in dde_tx_handler:
dde_linux26_net_get_mac_addr(1, (unsigned char*)_mac_addr.addr);
This schould be exactly that MAC address you shoud have configured when starting up qemu (did you?):
This could look like "-net nic,model=pcnet,macaddr=00:81:71:61:51:41"
Perhaps you forgot this step?
So you're saying that when i run the web server, I need to explicitly state the mac address as stated above? If so, what about the XP machine. I've tried setting the mac address to something different, but so far it hasn't worked. Let me try this again.
Thanks Peter

This is just an example taken from a different setup I was working on a few months ago. Of course, you're free to choose any MAC address you like (make sure that the first byte is an even number, otherwise, your packets might be ignored). I don't know exactly where qemu takes its virtual MAC address from when you omit it in the configuration, therefore it could be helpful to make them distinct in any case. My suggestion is nothing more than an uncertain idea, and I would always suggest to trace the whole packet flows with wireshark which would show quite obviously which interfaces uses which MAC address and which IP address has been assigned to it.

This statement is only applicable for nic_drv on Genode/Linux (os/src/drivers/nic/linux), where I had to implement a simple scheme according to what Qemu does with "-net nic,mac_addr=...". For the future, we plan to facilitate the config mechanism to make the MAC configurable on bootup.
Where could that MAC address come from? The driver obtains it from qemu in dde_tx_handler: dde_linux26_net_get_mac_addr(1, (unsigned char*)_mac_addr.addr);
This is from the the DDE-based nic_drv which certainly uses the hardware MAC address (linux_drivers/src/drivers/nic).
Greets
Sven,
OK, so now i've got 2 different mac addresses for each of the instances. However, it seems to me that the remote ip addresses obtained by the web server are the same, regardless of the machine making the request (ie. either the XP vm or the host browser). Any idea as to why this is happening? I mean, the IP address that XP obtains is not 10.0.0.1, yet when the web server receives a HTTP request, the IP address is always 10.0.0.1.
BTW, i used this command to run my XP instance:
kvm -localtime -cdrom Microsoft\ Windows\ XP\ Professional\ (SP2).iso -m 384 -boot d windows.img
In this case, I figured that I don't need to supply a mac address for the XP vm given the web server already has a unique mac address. Furthermore, I've had difficulties in assigning a mac address to the xp vm as i keep getting the following message:
Warning: vlan 0 is not connected to host network

Hi Peter, ÃÂ I'm not sure if I've got your setup right or not. ÃÂ You have a host operating system (guess linux) with two qemu instances,

running Windows XP and the other running genode with the webserver. ÃÂ Your host system also runs a dhcp server which assigns the same ip

Hi all,
I think i might have figured out my issue. The IP address of 10.0.0.1 corresponds to the TAP device, which suggests that the requests are coming from the TAP device (which it should be i think, unless someone can correct me). So i guess it might not actually be possible to get the starting IP address ie. the IP address of the XP VM (which is obviously not 10.0.0.1).

Any idea as to why this is happening? I mean, the IP address that XP obtains is not 10.0.0.1, yet when the web server receives a HTTP request, the IP address is always 10.0.0.1.
BTW, i used this command to run my XP instance:
kvm -localtime -cdrom Microsoft\ Windows\ XP\ Professional\ (SP2).iso -m 384 -boot d windows.img
In this case, I figured that I don't need to supply a mac address for the XP vm given the web server already has a unique mac address. Furthermore, I've had difficulties in assigning a mac address to the xp vm as i keep getting the following message:
Warning: vlan 0 is not connected to host network

Hi Peter, I think that it would be very helpful to trace what is actually happening. Have a look at the tcpdump utility or better at wireshark which is much more convenient to use. Both tools will show the actual message flows during both dhcp handshakes, in particular you can inspect which MAC addresses the packets contain, if any of the guests suggests a distinct IP address or if any vlan tag is set as your kvm indicates. Wireshark allows for saving the packet dump in a pcap file (as well as tcpdump does, of course) which you could post here. Cheers Sven

You're right, your host acts on behalf of the XP VM.
So i guess it might not actually be possible to get the starting IP address ie. the IP address of the XP VM (which is obviously not 10.0.0.1).
Wrong, it is - see below.

You configured the XP VM to use Qemu's "host networking". Please try tap-based networking similar to your Genode VM. For more information please refer to the Qemu documentation that is quite detailed about this topic.

Hi,
So just to clarify, what I meant by the following:
So i guess it might not actually be possible to get the starting IP address ie. the IP address of the XP VM (which is obviously not 10.0.0.1).
Wrong, it is
Is that i was thinking that it might not be possible to get the starting IP address from the web server when a HTTP request is received. I can obviously obtain the IP address of the XP vm by looking at the network settings. What I want to be able to do is obtain the IP address of the actual VM that made the HTTP request to the web server while in the web server for experimental purposes. I'm currently looking at some qemu documentation, and seeing if i can glean anything out of it. I'm thinking that possibly the XP vm would have its own tap device to the web server maybe?
Thanks Peter

I think i might have figured out my issue. The IP address of 10.0.0.1 corresponds to the TAP device, which suggests that the requests are coming from the TAP device (which it should be i think, unless someone can correct me).
You're right, your host acts on behalf of the XP VM.

BTW, i used this command to run my XP instance:
kvm -localtime -cdrom Microsoft\ Windows\ XP\ Professional\ (SP2).iso

You configured the XP VM to use Qemu's "host networking". Please try tap-based networking similar to your Genode VM. For more information please refer to the Qemu documentation that is quite detailed about this topic.

Hello,
unfortunately you got me wrong again. Please make yourself familiar with the differencies between Qemu "host networking" and "tap networking". No offense meant but I read the man page and used Google to understand how it works...
You should also have a look at the attached script and dhcp.conf, which gave me two Qemu instances communicating over a virtual bridged ethernet.
Cheers
Hi,
In looking at those scripts, that's basically what I have done. Thank you so much for your help Christian.
