我遵循了一些如何執行此操作的範例,所有這些範例最終都修改sshd_config
為
Subsystem sftp internal-sftp
Match User chubbyninja
ChrootDirectory %h
AllowTCPForwarding no
X11Forwarding no
ForceCommand /usr/lib/openssh/sftp-server
當我這樣做時,我sshd -t
會確保沒有錯誤service sshd restart
重新啟動後,我嘗試 SFTP(使用 filezilla),但我不斷收到
Response: fzSftp started
Command: open "[email protected]" 22
Command: Pass: ********************
Error: Network error: Software caused connection abort
Error: Could not connect to server
如果我將設定恢復到原始狀態,我可以正常使用 SFTP,但隨後我可以瀏覽任何目錄。我只需要用戶在其主目錄中的地方
我的預設配置中有這一行:
Subsystem sftp /usr/lib/openssh/sftp-server
這就是我替換與上述詳細資料。
儘管我有 root 存取權限,但我只能透過 ssh 存取這台機器。
更新 在遵循 sam_pan_mariusz 的建議後,它似乎變得更進一步,但現在我明白了
Response: fzSftp started
Command: open "[email protected]" 22
Error: Network error: Connection refused
Error: Could not connect to server
更新2
我也遵循了 Froggiz 的建議,並將我的配置更改為:
Subsystem sftp internal-sftp -u 0007 -f AUTH -l VERBOSE
Match Group chubbyninja
ChrootDirectory /home/chubbyninja
ForceCommand internal-sftp -u 0007
AllowTcpForwarding no
GatewayPorts no
X11Forwarding no
但我得到了原件軟體案例連線中止
我進行了監控/var/syslog
,但沒有顯示任何內容來表明出現此錯誤的原因
更新 3 - 新增了 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

# For this to work you will also need host keys in /etc/ssh_known_hosts

# Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication
#IgnoreUserKnownHosts yes
# To enable empty passwords, change to yes (NOT RECOMMENDED)

# Set this to 'yes' to enable PAM authentication, account processing,

# 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
Match Group chubbyninja
ChrootDirectory /home/chubbyninja
AllowTCPForwarding no
X11Forwarding no
GatewayPorts no
ForceCommand internal-sftp -u 0007
答案1
這就是我為特定使用者設定 sftp 的方式
1]創建用戶
adduser {USER}
2]編輯/etc/ssh/sshd_config
PasswordAuthentication yes
Subsystem sftp
internal-sftp -u 0007 -f AUTH -l VERBOSE
Match Group {USER}
ChrootDirectory {FOLDER}
ForceCommand internal-sftp -u 0007
AllowTcpForwarding no
GatewayPorts no
X11Forwarding no
3]為使用者設定權限
chmod -R 777 {FOLDER}
4]重新啟動ssh
service ssh restart
將 {USER} 替換為您的用戶,將 {FOLDER} 替換為您的資料夾,它應該可以工作! ;)
你能把你完整的 ssh 設定嗎?
答案2
我不太明白問題中的“替換”部分,但是......在 SSH 中進行 chroot 時,部隊指揮部應指內部子系統名稱。在您的情況下,整行應為:ForceCommand sftp
。
如果你想使用可執行路徑克羅特,您必須準備適當的 chroot 目錄(包含可執行檔案連結到的程式庫、設定等)。
我的工作配置中的相關行:
Subsystem sftp /usr/lib/openssh/sftp-server
Match User testuser1
ChrootDirectory /one/dir/path/
ForceCommand internal-sftp
