无法SSH进入Ubuntu Touch设备

从我的电脑：

cameron@cameron-ubuntu:~$ ssh phablet@192.168.99.124 Permission denied (publickey). 

所以看来手机上的openssh没有启用密码validation。 但在我看来它应该是这样的。 来自手机的/ etc / ssh / sshd_config是默认值：

 # Package generated configuration file # See the sshd_config(5) manpage for details # What ports, IPs and protocols we listen for Port 22 # Use these options to restrict which interfaces/protocols sshd will bind to #ListenAddress :: #ListenAddress 0.0.0.0 Protocol 2 # HostKeys for protocol version 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key HostKey /etc/ssh/ssh_host_ecdsa_key HostKey /etc/ssh/ssh_host_ed25519_key #Privilege Separation is turned on for security UsePrivilegeSeparation yes # Lifetime and size of ephemeral version 1 server key KeyRegenerationInterval 3600 ServerKeyBits 1024 # Logging SyslogFacility AUTH LogLevel INFO # Authentication: LoginGraceTime 120 PermitRootLogin without-password StrictModes yes RSAAuthentication yes PubkeyAuthentication yes #AuthorizedKeysFile %h/.ssh/authorized_keys # Don't read the user's ~/.rhosts and ~/.shosts files IgnoreRhosts yes # For this to work you will also need host keys in /etc/ssh_known_hosts RhostsRSAAuthentication no # similar for protocol version 2 HostbasedAuthentication no # Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication #IgnoreUserKnownHosts yes # To enable empty passwords, change to yes (NOT RECOMMENDED) PermitEmptyPasswords no # Change to yes to enable challenge-response passwords (beware issues with # some PAM modules and threads) ChallengeResponseAuthentication no # Change to no to disable tunnelled clear text passwords #PasswordAuthentication yes # Kerberos options #KerberosAuthentication no #KerberosGetAFSToken no #KerberosOrLocalPasswd yes #KerberosTicketCleanup yes # GSSAPI options #GSSAPIAuthentication no #GSSAPICleanupCredentials yes X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes #UseLogin no #MaxStartups 10:30:60 #Banner /etc/issue.net # Allow client to pass locale environment variables AcceptEnv LANG LC_* Subsystem sftp /usr/lib/openssh/sftp-server # Set this to 'yes' to enable PAM authentication, account processing, # and session processing.

UsePAM yes 

我也尝试使用PasswordAuthentication yes （即取消注释，但在我看来，“是”是默认值）。

另外，如果它包含一些我不知道的有用信息，ssh -v：

Answer 1

手机上的SSH守护程序随选项一起运行

 /usr/sbin/sshd -D -o PasswordAuthentication=no 

它会覆盖配置文件中的任何选项。 可能很难改变这一点。

在这种情况下，设置公钥认证可能更容易（也更安全）。 将您的公钥粘贴到/home/phablet/.ssh/authorized_keys2 。 是的，最后有一个2，这让我觉得甚至没有使用/etc/ssh/sshd_config 。

您只需要一种初始登录手机的方法。 尝试使用adb shell或Ubuntu SDK中的Qt Creator中的按钮来启用开发人员模式，设置公钥认证等。

Answer 2

/etc/init/ssh.override是覆盖默认ssh选项的那个。

 cat /etc/init/ssh.override manual exec /usr/sbin/sshd -D -o PasswordAuthentication=no 

所以你可以从这里删除它。

Answer 3

在手机上安装终端应用程序。 切换到开发人员模式（在设置/关于设备）并设置密码（不是pin）。 运行终端并输入此命令

/ usr / sbin目录/ sshd的

现在，您可以使用计算机中的ssh连接到设备（例如）

ssh phablet@192.168.1.100

使用切换到开发人员模式时放入的密码。 当然，IP地址需要是你手机的IP。 如果您不知道，只需在手机终端中运行ifconfig命令并在wlan界面附近查找IP。

如果您希望下次更容易，请将密钥从计算机复制到移动设备

ssh-copy-id phablet@192.168.1.100

下次您不需要密码，甚至可能禁用开发人员模式。 仍然需要运行ssh服务器，这次使用命令

sudo /etc/init.d/sshd重启
