SSHサーバーに接続して使用しましたscreen。その後ログアウトしました。
約10時間後にクライアントが再起動した後、サーバーに接続できなくなりました。パスワードを入力した後、1〜2分間何も起こらず、次のメッセージが表示されます。
packet_write_wait: Connection to xxx.xxx.xxx.xxx port 22: Broken pipe
私は何を実行しようとしていますこの回答次のようにコマンドしてください。
ssh -n username@server server kill -HUP -1
しかし、同じエラーメッセージが表示されます。また何ができますか？
接続しようとすると、次の結果が表示されます。-vvv
