that was a little heart breaking.
The EOS utilizes ELBE which uses Debian.
The roadside RSU server application actually utilizes SNMP for a lot of
functionality and includes a honeypot called herbert.
The /mnt/rescuefs/usr/tmplt/etc/elbe_base.xml seems to contain the 'kapsch'
user's default password but as you can probably guess, it isn't actually.

To decode the I2C data when gathering it via bus pirate, you can use xxd.
Or, in powershell:
[System.Text.Encoding]::ASCII.GetString(([byte[]](I2C-HEX)))
You can test the CV2X radios with the acme binary by using the following
commands:
/etc/init.d/start_cv2x_le start
cv2x-config --register-sps-flow 1,10,1,200,287,2500,2600
acme -RVAe -i rmnet_data1
acme -A -i rmnet_data1
Alternatively, for the 9160s you can do the following:
ip link show
cd /mnt/c3platpersistent/opt/11p/bin/llc-v13
sudo ./llc chconfig -s -w SCH -c 172 -r b -m MK2MCS_R12QPSK -p 33
sudo ./llc chconfig -s -w CCH -c 172 -r b -m MK2MCS_R12QPSK -p 33
sudo ip link
set cw-llc promisc on
sudo ip link set wave1 promisc on
sudo ip link
set cw-mon-rxb promisc on
sudo ip link set cw-mon-txb promisc on
sudo tcpdump -i wave1 -w /home/kapsch/microSD/wave1_traffic.pcap &
sudo tcpdump -i cw-llc -w /home/kapsch/microSD/cw_llc_traffic.pcap
Then run a simple loop to check for valid data coming in:
while true; do ./llc count | grep 'Rx MAC Valid Data Frames\|Rx MAC
Broadcast Frames' && sleep 3; done
You can also monitor the following directories for logs:
/var/log/pcap/RadioA/
/var/log/pcap/RadioB/
/mnt/c3platpersistent/var/log/
/home/kapsch/microSD/*pcap
If your unit has both radios:
sudo ip link set wave-raw promisc on
sudo ip link set wave-mgmt promisc on
sudo tcpdump -i wave-raw -w dsrc_traffic.pcap
sudo tcpdump -i wave-mgmt -w dsrc_traffic.pcap
sudo ip link set wave0 up
sudo ip link set wave0 promisc on
sudo ./llc chconfig -s -w CCH -c 178 -r a -m MK2MCS_R12QPSK -p 33
sudo ./llc chconfig -s -w SCH -c 178 -r a -m MK2MCS_R12QPSK -p 33
sudo tcpdump -i wave0 -w /home/kapsch/microSD/wave0_traffic.pcap
Now this is just what I've concluded and I have not gone through all
channels and modulations yet. I did however, drive for about 20 minutes
with an RSU sniffing and found no signals.
On my website, gainsec.com I've also gone through how to use a SDR to
sniff/send out V2X packets which helped confirm that these test binaries
were working as expected.
