The sending computer has two nics, eno1 for the internal network and eno2 is on the internet. So, my netconsole stanza said netconsole=@192.168.0.1/eno1,@192.168.0.2 The box which is at 192.168.0.2 has netcat (windows version) and I tried the following: netcat -u -v -l 192.168.0.2 6666 and I also tried 192.168.0.1 6666 which is the ip address of the linux console which I am trying to debug. I also tried 0.0.0.0 6666 which did not work either, but I think the windows firewall was blocking, and I did fix that, but did not try the 0.0.0.0 after that. So, what am I doing wrong here? -- Your life is like a penny. You're going to lose it. The question is: How do you spend it? John Covici wb2una covici@ccs.covici.com
