Ubuntu
無法從 Windows 10 SSH 進入虛擬機（之前可以正常工作）
我在我的主機 Windows 10 機器上的 Oracle Virtual Box 中執行 Ubuntu 14 VM，用於執行 mininet 的大學作業。一切都執行良好，直到有一天我醒來並嘗試通過 ssh 連接到虛擬機，它讓我登錄（顯示歡迎消息），但沒有顯示提示。就像它只是一條閃爍的線，表示我可以輸入，但如果我按 Enter 或任何其他操作，我的電腦會發出嗶聲，然後按
Ctrl+D結束它。我使用 SSH
ssh user@ip它在前一天執行得非常好，我不記得做過任何會毀掉它的改變。我已經解除安裝了 VM 映像並重新導入了新版本，我已經重新安裝了虛擬機，並嘗試了 VM 內的各種設置以使其工作但無濟於事。我可以使用 PuTTy SSH 進入 VM，但我需要使用 Visual Studio，它不支持 PuTTy。我覺得問題出在我的主機上，但我無法弄清楚它是什麼。
關於我可以做些什麼來嘗試修復它的任何提示？
使用下面的 -v 命令更新。
Ctrl我用+手動關閉連接後連接關閉D。歡迎消息顯示，但之後什麼都沒有，只是游標閃爍。PS C:\WINDOWS\system32> ssh -v cs551@192.168.56.10 OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5 debug1: Reading configuration data C:\\Users\\HP/.ssh/config debug1: C:\\Users\\HP/.ssh/config line 1: Applying options for 192.168.56.10 debug1: Connecting to 192.168.56.10 [192.168.56.10] port 22. debug1: Connection established. debug1: identity file C:\\Users\\HP/.ssh/id_rsa type 0 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_rsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_dsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_ecdsa type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_ecdsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_ed25519 type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_ed25519-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_xmss type -1 debug1: key_load_public: No such file or directory debug1: identity file C:\\Users\\HP/.ssh/id_xmss-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_for_Windows_7.7 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 debug1: match: OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 pat OpenSSH_6.6.1* compat 0x04000000 debug1: Authenticating to 192.168.56.10:22 as 'cs551' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: curve25519-sha256@libssh.org debug1: kex: host key algorithm: ecdsa-sha2-nistp256 debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: <implicit> compression: none debug1: kex: client->server cipher: chacha20-poly1305@openssh.com MAC: <implicit> compression: none debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ecdsa-sha2-nistp256 SHA256:wDmGnoAN/7DHHH1OTiFsKC3l4v5PYvxOm659KKLCDwk debug1: Host '192.168.56.10' is known and matches the ECDSA host key. debug1: Found key in C:\\Users\\HP/.ssh/known_hosts:1 debug1: rekey after 134217728 blocks debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: rekey after 134217728 blocks debug1: pubkey_prepare: ssh_get_authentication_socket: No such file or directory debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Offering public key: RSA SHA256:iMnIfpXDKQgmDCnJSUpBS1x4uOM3gXOa888wrKwkLDI C:\\Users\\HP/.ssh/id_rsa debug1: Authentications that can continue: publickey,password debug1: Trying private key: C:\\Users\\HP/.ssh/id_dsa debug1: Trying private key: C:\\Users\\HP/.ssh/id_ecdsa debug1: Trying private key: C:\\Users\\HP/.ssh/id_ed25519 debug1: Trying private key: C:\\Users\\HP/.ssh/id_xmss debug1: Next authentication method: password debug1: read_passphrase: can't open /dev/tty: No such file or directory cs551@192.168.56.10's password: debug1: Authentication succeeded (password).

(1) 首先，您可以通過在 Linux 機器上執行以下命令來重新配置 SSH 伺服器：
sudo dpkg-reconfigure openssh-server如果上述命令失敗，只需在 Linux 機器上重新生成 SSH 密鑰：
$ ssh-keygen -b 2048 -t rsa(2) 其次，您以管理員身份打開 PowerShell (PS)。您需要以普通使用者身份打開 PS，您現有的 SSH 環境變數所在的位置，然後 SSH 將再次工作。
(3) 第三，從你的 Windows 機器中刪除舊的 SSH 公鑰
$ ssh-keygen -R 192.168.56.10(4) 然後終於可以正常SSH了。
