無法在 Virtualbox 上通過 SFTP 進入我的 Ubuntu 伺服器，SSH 工作正常

我有一個在安裝了 OpenSSH 的 VirtualBox 中執行的 Ubuntu 10.10 伺服器。我已將主機上的 8888 埠轉發到來賓上的 80，將主機上的 2222 轉發到來賓上的 22。出於某種原因，我可以使用 localhost:2222 SSH 進入該伺服器就好了，但是當我嘗試在 localhost:2222 上使用 WinSCP 進行 SFTP 時，我收到“連接被拒絕”錯誤。這是我的 sshd_config 文件，如果有幫助的話：

# 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
#Privilege Separation is turned on for security
UsePrivilegeSeparation 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

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

**更新：**出於好奇，我安裝了 FileZilla 並嘗試與之連接。它工作得很好。顯然問題出在 WinSCP 端，而不是伺服器端。我會再調查一下。

嗯，我不知道該怎麼做，所以我想我會回答我自己的問題。我發布了對該問題的更新，但似乎人們錯過了它。

我不認為 sftp 可以讓您:port添加到主機名的末尾。你可以試試

sftp -o Port=2222 localhost

反而
