Per "Bang Path" den Lauf einer Mail steuern hilft auch einfacher Test.
Das hatte ich bei 3 Knoten schonmal gemacht, aber als der Pi0W dazu kam einfach nochmal probiert.
Schreiben:
Code: Alles auswählen
(yeti@kumari:1)~$ mail -s 'kumari - cubietruck1 - pi1-a - pi0w-a - kumari' 'cubietruck1!pi1-a!pi0w-a!kumari!yeti' <<< '4 node circle mail'
Die "Anrufe" der Systeme untereinander stoße ich noch immer nur manuëll an.
Und dann gab's Post:
Code: Alles auswählen
(yeti@kumari:1)~$ cat ~/Maildir/cur/1617901733.V801I203ecfM368100.kumari\:2\,
