The docs are at: https://www.kernel.org/doc/Documentation/networking/netconsole.txt (you can also google for linux netconsole for some wiki articles on it) I have on my command line: netconsole=@/,6666@10.1.0.52 That IP is the host I want the log traffic to go to. (Read the docs if you have a more complicated networking setup - I assume that will just run ARP and send stuff out without using a gateway/etc.) Then on a receiving linux host I'd run (I think - it has been a while): nc -u -l -p 6666 Now, you mentioned Windows. I've never used it, but nmap has a program available in a windows version called ncat that might do the job: https://nmap.org/ncat/ You just want to make sure you have it listening on port 6666 for UDP. Make sure you use UDP or you won't receive anything. If it is working you should get a ton of log spam when your host boots - anything that shows up in dmesg will show up in the network console. It is sent in realtime. -- Rich
