tunslip6
|
|
========
|
|
|
|
tunslip6 can be used in host side to create a tun device that
|
|
is connected to a unix socket that qemu is providing. This
|
|
way it is possible to pass packets between host and target
|
|
system via slip protocol.
|
|
|
|
You need to connect tunslip6 to the second qemu serial line
|
|
through a UNIX socket (qemu option -serial unix:/tmp/slip-socket).
|
|
|
|
1) Start socat
|
|
|
|
$ socat PTY,link=/tmp/slip.dev UNIX-LISTEN:/tmp/slip.sock
|
|
|
|
2) Start qemu, use the listener demo app. Note that you need to
|
|
set CONFIG_NETWORKING_UART=y in your configuration.
|
|
|
|
You might need to set the platform and ARCH like this if simple_uart
|
|
driver is not found in your default platform.
|
|
|
|
$ make PLATFORM_CONFIG=basic_cortex_m3 ARCH=arm \
|
|
QEMU_EXTRA_FLAGS="-serial none -serial unix:/tmp/slip.sock" qemu
|
|
|
|
3) Start tunslip6
|
|
|
|
$ sudo ./tunslip6 -s `readlink /tmp/slip.dev` 2001:db8::1/64
|
|
|
|
4) Send data to listener
|
|
|
|
$ nc -u -6 2001:db8::2 4242 <<EOF
|
|
foobar
|
|
EOF

tunslip
|
|
=======
|
|
|
|
tunslip if for IPv4 networks and it can be used in host side
|
|
to create a tun device that is connected to a unix socket that
|
|
qemu is providing. This way it is possible to pass packets
|
|
between host and target system via slip protocol.
|
|
|
|
You need to connect tunslip to the second qemu serial line
|
|
through a UNIX socket (qemu option -serial unix:/tmp/slip-socket).
|
|
|
|
1) Start socat
|
|
|
|
$ socat PTY,link=/tmp/slip.dev UNIX-LISTEN:/tmp/slip.sock
|
|
|
|
2) Start qemu, use the listener demo app. Note that you need to
|
|
set CONFIG_NETWORKING_UART=y in your configuration.
|
|

$ make PLATFORM_CONFIG=basic_cortex_m3 ARCH=arm \
|
|
QEMU_EXTRA_FLAGS="-serial none -serial unix:/tmp/slip.sock" qemu
|
|
|
|
3) Start tunslip
|
|
|
|
$ sudo ./tunslip -s `readlink /tmp/slip.dev` 192.0.2.1 255.255.255.0
|
|
|
|
4) Send data to listener
|
|
|
|
$ nc -u 192.0.2.2 4242 <<EOF

echo-client
|
|
===========
|
|
|
|
echo-client is a tool that is run in Linux host side and
|
|
which sends pre-defined UDP data packets to echo-server
|
|
application that is running in qemu side. This client
|
|
process verifies that it is able to receive data correctly
|
|
from the echo-server and thus verify that the upper layer
|
|
networking components in Zephyr IP stack work properly.
|
|
|
|
You needs to setup the slip connection (see the steps 1 to 3)
|
|
in tunslip6 section of this document.
|
|
|
|
Example:
|
|
|
|
$ ./echo-client 2001:db8::2
|
|
|
|
In order to send multicast IPv6 packets, one needs to
|
|
give the network interface as a parameter.
|
|
|
|
$ ./echo-client -i tun0 ff84::2
