Wenn ich versuche, eine X11-Weiterleitungsverbindung zu herzustellen, myserverwird die folgende Fehlermeldung angezeigt:
% ssh -X myserver xlogo
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
Error: Can't open display: localhost:10.0
%
(Ich erhalte den gleichen Fehler, wenn ich -Yanstelle von verwende -X. In beiden Fällen sehe ich das xlogoFenster nie .)
Wenn ich denselben Befehl verwende, um eine Verbindung zu einem anderen Server herzustellen, funktioniert dies einwandfrei (dh das xlogoFenster wird erwartungsgemäß angezeigt), sodass ich vermute, dass das Problem bei myserver(und nicht bei meiner lokalen Konfiguration) liegt.
Auch wenn ich stattdessen benutze
% ssh -X myserver
Die Verbindung ist erfolgreich und ich werde angemeldet myserver. Wenn ich dann laufe xlogo, erhalte ich den gleichen Fehler wie oben gezeigt.
Übrigens ist der lokale SSH-Client / X11-Server ein Ubuntu-Laptop, und der Remote-SSH-Server / X11-Client ist eine Workstation, auf der OS X Lion ausgeführt wird.
Ich habe auch ausgeführt ssh -vvvX myserver xlogo, aber die umfangreiche Ausgabe ist für mich nicht sehr aussagekräftig und ich kann das Problem nicht daraus diagnostizieren. (FWIW, ich habe diese Ausgabe unten kopiert.)
Wie kann ich dieses Problem weiter beheben?
% ssh -vvvX myserver xlogo
