sshはコマンドの送信でスタックしますが、コマンドなしでログインできます

Xyzをマシンにsshすることができます:

$ ssh xyz 
[email protected]'s password: 
Last login: Fri Sep  1 12:37:10 2017 from 192.168.1.23
[email protected]:~$ 

しかし、それにscpを送信することも、sshを介してコマンドを送信することもできません。したがって、たとえば、ssh xyz echo helloがスタックします。

私はすでに インタラクティブセッションをチェックしています サーバーユーザーの.bashrcスクリプトで、使用するように/etc/ssh/sshd_configを変更しようとしました

UsePAM no

しかし、それは何も変わりませんでした。関連する場合は、同じWi-Fiネットワーク上でMacOS10.11からUbuntu16.04ボックスに接続しようとしています。

ssh -vvv xyz echo helloの出力は次のとおりです。

-tフラグを追加しようとしましたが、sshコマンドの送信は機能しますが、それでもscpを機能させることができません。これはssh -vvv -t xyz echo helloの出力です。

質問ですでに述べたように、OPは-tオプションを追加することでsshを機能させました。これにより、仮想TTYデバイスが強制的に作成されますが、sshを使用してリモートシステム間でファイルをコピーするscpを機能させるのに苦労しました。
scp用の仮想TTYデバイスの作成を強制するには、-oパラメーターと、それに続くsshの構成ファイルと同じスタイルで記述されたsshオプションのリストが必要です。したがって、この場合は-o RequestTTY=force
