【问题描述】：

当我尝试从我的 mac（ssh ip 地址）ssh 到我的 ubuntu 服务器时，我收到以下错误：权限被拒绝（公钥）。我想通过密码或密钥通过 ssh 连接，无论哪个可以完成工作。感谢您的帮助:)

我修改的文件是/etc/ssh/sshd_config：

# 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

# Logging

# Authentication:
LoginGraceTime 120
#PermitRootLogin without-password
PermitRootLogin yes
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

Subsystem sftp /usr/lib/openssh/sftp-server

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM yes

#AllowTcpForwarding no

#X11Forwarding no

【问题讨论】：

您使用哪个用户名进行连接？

标签： macos ubuntu ssh

【解决方案1】：

您应该为 ubuntu 安装一些防火墙软件，然后验证您希望通信发生的端口。如果您需要相同的图形版本，您可以使用 gufw。

【解决方案2】：

从 Mac 使用 ssh 时，您必须指定您尝试登录的用户名。

所以如果你在你的 ubuntu 服务器上的用户名是 user 并且你的 ip 是 10.0.0.1 那么你会这样做：

ssh user@10.0.0.1

它会提示你输入 ubuntu 密码。

输入，回车。

您现在应该登录到您的 ubuntu 服务器。
