Konfigurieren der bidirektionalen hostbasierten Authentifizierung in SSH


0

Ich habe 3 Server (Ruby, Sapphire, Onyx), die ich versucht habe, eine kennwortlose (hostbasierte) Authentifizierung für alle Benutzer einzurichten. Ich habe die Maschinen für die Verwendung der hostbasierten Authentifizierung konfiguriert und die Optionen ssh_config, sshd_config, shosts.equiv und ssh_known_hosts pro geändert dieser Leitfaden .

Dieser Fehler tritt jedoch auf, wenn ich versuche, eine Verbindung zwischen einer der Maschinen (Ruby) und einer der anderen Maschinen (Sapphire) herzustellen:

get_socket_address: getnameinfo 8 failed: Name or service not known
get_socket_address: getnameinfo 8 failed: Name or service not known
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,hostbased).

Bitte beraten.

Ich kann Konfigurationsdateien und ausführliche Ausgaben auf Anfrage zur Verfügung stellen. Ich möchte dies am Anfang nicht veröffentlichen, es sei denn, dies ist aufgrund des Volumes erforderlich.

Edit 1: Auf den Servern wird OpenSSH_5.3p1 auf Centos 6.8 ausgeführt

Edit 2: Ausgabe des SSH-vvv-Debugmodus:

Ich habe die Debug-Ausgabe von SSH hinzugefügt. Wünschen Sie etwas anderes?
Boss1295

Sie müssen DNS zwischen den Servern ordnungsgemäß einrichten.
Jakuje

Sie sind lokal vernetzt und kennwortbasierte Authentifizierung funktioniert einwandfrei.
Boss1295

der suer, der versucht, ssh zu versuchen, ist root (ruby & amp; saphire)? Wenn ja, müssen die richtigen Schlüssel für / root nicht ~ / angegeben werden. Beachten Sie auch, dass der Benutzer, der mit einem anderen Host ssh'ing ist, nicht mit dem Remote-Host identisch sein muss. Wenn dies jedoch der Fall ist (wenn sich die Benutzernamen auf den jeweiligen Hosts unterscheiden) Schlüssel für den beabsichtigten Remote-Benutzernamen MÜSSEN in der Datei authorized_keys auf dem Remote-Host enthalten sein.
