[SOLVED] FreeDOS in qemu: no internet-connection

Hi altogether,

I want to get FreeDOS going within qemu.

I downloaded the respective iso-file and the installation went well.
In principle FreeDOS works fine with the exception of networking. I simply can´t get qemu to let FreeDOS connect to the internet.

My command-line is:

qemu-system-i386 -m 32M -drive file=drivec.img,media=disk,format=raw -drive file=FD12CD.iso,media=cdrom -boot order=d

or even

qemu-system-i386 -m 32M -drive file=drivec.img,media=disk,format=raw -net nic,model=ne2k_pci -drive file=FD12CD.iso,media=cdrom -boot order=d

.

According to the instructions on http://wiki.freedos.org/wiki/index.p...tworking_HowTo I installed FDNET, mTCP and wget
in FreeDOS. So things should work. Yet they don´t.

After a reboot FreeDOS says: "Error: Your ethernet card reported an error for every packet we sent."
And with "-net nic,model=ne2l_isa" in command-line:
"Your DHCP server never responded and no packets were seen on the wire."

My terminal says: " Warning: vlan 0 is not connected to host network".
qemu montitor says:

info network

hub 0
\hub0port0: ne2k_pci.0: index=0,type=nic,model=ne2k_pci,macaddr=52:54:00:12:34:56

I compared the values with those given on http://qemu-buch.de/de/index.php?tit..._konfigurieren.
They should be correct. So that´s it.

Curious thing however: When firing up any other OS, e.g. KNOPPIX with qemu the internet connection works perfectly:

kvm --cdrom KNOPPIX_V7.0.5CD-2012-12-21-DE.iso -m 512 -boot d

.

Does anybody know what to do?

Tnx a lot in advance.

I have not used QEMU with FreeDOS. I have used other tools, just not QEMU. If I get a chance I will try to replicate the behavior and post what I discover.

cool.

Hi all,

thanks for the reply.
In the meantime I subscribed to the qemu mailing list and discussed the problem there.

I seems I could come up with a solution.

Warning: vlan 0 is not connected to host network

means the following:

This means you have given QEMU a command line which defines a network card but no network backend, so you get a virtual bit of ethernet that's not connected to anything. If you're using old-style "-net nic,..." then you must also pass "-net user" or some other -net option specifying the backend. Similarly if you're using new-style -device to specify the network adaptor type then you must also pass a -netdev option to specify the backend. (If you specify no -net/netdev options at all then you get a default which is -net user and some network adaptor which depends on the machine type; but if you specify any -net options then you get no defaults provided by QEMU and you have to specify all of the relevant options yourself.)

Further suggestion:

Try a different NIC, eg with -net nic,model=ne2k_isa -net user

So I typed "qemu-system-i386 drivec.img -net nic,model=help" into the terminal.

That gave me as valid options:

qemu: Supported NIC models:
ne2k_pci,i82551,i82557b,i82559er,rtl8139,e1000,pcnet,virtio"

I finally came up with a command line that worked for me:

qemu-system-i386 -m 32M -drive file=drivec.img,media=disk,format=raw
-net nic,model=pcnet -net user -drive file=FD12CD.iso,media=cdrom -boot
order=d

Thanks for the update and solution. I looked at this and didn't have a wild guess even.

Hi,

you´re welcome. I´m always glad when I can get help here. So this time I´m happy to provide whoever is interested with the solution to the problem.
