Thanks, that helped alot on the L4 ore side. Arping seems to run fine now except that packets seem not to be making it to and from the host network . Do I need to configure something for the tunnel for fiasco-ux ??

Hello,
When I run under fiasco-ux:
./fiasco -N -s -l names -l dm_phys -l log -l "l4io --noirq" -l ore -l ore_test_arping
First, please add "-n9" to your command line. This enables task 9 (ore) to execute native system calls using int80.
ore | main(): Initialized 1 network devices. ore | Device = lo, IRQ = 0, MAC = 00:00:00:00:00:00
There should be 2 network devices: lo and eth0. The arping test tries to open eth0 and this fails because of the missing device.
Please do a "make cleanall" in your l4/pkg/ore directory. Then "make config" in l4/pkg/ore/server and configure the server to run with Fiasco UX only. Thereafter rebuild the ORe directory. This will compile the ux_net driver into the ORe server, which in turn will provide an eth0 interface.
Note that "make cleanall" also erases configuration files. A subsequent "make" will use the default config from l4/pkg/ore/server/defconfig. By default this builds ORe with a real network driver again. If you are only using UX, you might copy your .config to defconfig so that "make cleanall && make" builds ORe for UX.
So far Bjoern

Do I need to configure something for the tunnel for fiasco-ux ??
I suppose, Fiasco is configured with the UX_NET option.
From where do you perform arping?
Bjoern
I used arping from both the host and another pc connected to the same switch. From the remote machine I was able to apring the real host runing fiasco-UX but not ore_test_arping. I have compiled in UX_NET for fiasco-ux. Fiasco-ux created tun0 when executed with -N switch. But if I ifconfig tun0 is it down If I ifconfig tun0 up then I can tcpdump tun0 and nothing is comming through the tunnel when arping. If I use uip_ore_client and ifconfig tun0 up then I the tcpdump shows the arp_who_has request and the reply from the host machine but then only the sends from the uip_ore_cleint. Seems like I need to set up some routing or bridgeing or something but no luck so far. Any suggestions would be appriciated jeff ----- Original Message ----- From: "Bjoern Doebel" <doebel@os.inf.tu-dresden.de> To: "Hieb,Jeffrey Lloyd" <jlhieb01@louisville.edu> Cc: <l4-hackers@os.inf.tu-dresden.de> Sent: Thursday, June 01, 2006 3:35 AM Subject: Re: ore with fiasco-ux

If this persists with the arping command line above, your host configuration seems to prevent arpinging. No idea about that.

For uip_ore I successfully tried: 1. fiasco -m64 -N -R l4v2/roottask -S l4v2/sigma0-ux \ -l l4v2/names" -verbose 1" \ -l l4v2/log \ -l l4v2/dm_phys \ -l l4v2/l4io \ -l l4v2/ore -n 9 \ -l l4v2/uip_ore_server 2. ifconfig tun0 10.0.0.1 3. ping 10.0.0.99 I set MY_IP to "10.0.0.99" in l4/pkg/ore/examples/uip_ore/server.c before.
