FTP changes
Track of my Cycling FTP changes (I’d love to say “progression” but it is not always like that…)
Note to self – places to update my FTP:

Pi-diet as a quorum device for Proxmox — /usr/lib/sftp-server: No such file or directory
There is a lot of good descriptions how to set it up, however – as Pi-diet does not use classic sshd but `dropbear` `pvecm qdevice setup` does not work:
# pvecm qdevice setup 192.168.1.202 -f
/bin/ssh-copy-id: INFO: Source of key(s) Proxmox monitoring
A toolset to gather temperature and power consumption metrics then collect in Prometheus. Can be found on GitHub https://github.com/jaroslawhartman/proxmox-monitoring/tree/main
Architecture
Components
- Proxmox Server 8.1.3
Host
Collecting script is running every minute on the pve host
* * * * * Proxmox Cloud-Init
- Custom Cloud-Init configuration
As stated in Proxmox Doc, you can create a custom Cloud-Init config where you’re free to set all parameters you need in a snippet yaml file, then generate a Cloud-Init custom image

Convert Diameter msg hex string to Wireshark pcap
A “raw” hex string can be converted into Wireshark pcap:
query="<hex string here>"
export FILE="$HOME/Downloads/capture"
echo -n "${query}" > "${FILE}.bin.txt"
xxd -r -p "${FILE}.bin.txt" | od -Ax -tx1 > "${FILE}.hex.txt"
/Users/jhartman/Tools/Utilities/Wireshark.app/Contents/MacOS/text2pcap -o none -E wireshark-upper-pdu -P diameter -F pcap "${FILE}.hex.txt" …Live Wireshark diameter capturing from K8s container (in Google Kubernetes Engine)
Handy command to remotely capture tcpdump from a K8s container located in Google Kubernetes Engine and then display it (live!) in Wireshark running on your PC:
% gcloud beta compute ssh jumphost --quiet --command='kubectl exec tra-rt-ag1-0 --namespace=app-ns -- sudo /usr/sbin/tcpdump
