Yes, the login sequence starts from a shell on pi4 RapiOS workstation, via ssh to the terminal server where tip is run to access the usb-serial adapter plugged into it. > > Starting with what you showed via: > > http://www.zefox.net/~fbsd/tiptrouble/corrupt_mac > > (not knowing how you got there) . . . > > QUOTE > FreeBSD/arm (www.zefox.net) (ttyu0) > > login: root > Password: > Corrupted MAC on input. > ssh_dispatch_run_fatal: Connection to 50.1.20.29 port 22: message authentication code incorrect > END QUOTE > > 50.1.20.29 is supposedly ns2.zefox.net instead of www.zefox.net > or ns1.zefox.net according to http://www.zefox.net/~fbsd/netmap .

The netmap is corrected, with a description of the login sequence used to watch the serial consoles added. I _think_ it's a bit clearer than before, if not please say so.
