无法通过 sftp 进入 ubuntu 服务器

嘿伙计们，我已经设置了一个 openssh 服务器，但是我仍然无法通过 sftp 或 ftp 进入我的 ubuntu 服务器。

我每次尝试登录时都会收到登录失败错误。我正在运行 ubuntu 14.10

我想说我的问题出在我的 sshd_config 文件中，但我不太愿意阅读该文档。在服务器方面我是业余爱好者，所以请保持友好。

# 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

# Don't read the user's ~/.rhosts and ~/.shosts files

# 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)

# Change to no to disable tunnelled clear text passwords

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

谢谢你们所做的一切，帮助我变得更好。

如果您尝试使用 root 帐户通过 SSH 登录，默认情况下，Ubuntu 会像您遇到的情况一样提示“否”。如果您必须允许 root 访问（非常危险），请将“AllowRootLogin”更改为“是”。更好的方法是创建一个新用户：

$adduser serveradmin
$passwd serveradmin (enter the password for the new account)

然后，您可以根据需要将 serveradmin 添加到 sudoers 组。我将在另一篇文章中讨论这个问题。

祝你好运！
