当我尝试连接到 filezila 上的 ftp 服务器时，如何修复此错误：
GnuTLS error -15: An unexpected TLS packet was received.
sublime ftpsync 插件出现以下错误：
ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1515)
这是我的 vsftpd 设置：
listen=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
nopriv_user=vsftpd
virtual_use_local_privs=YES
guest_enable=YES
user_sub_token=$USER
local_root=/var/www/$USER
chroot_local_user=YES
hide_ids=YES
guest_username=vsftpd
rsa_cert_file=/etc/ssl/private/vsftpd.pem
rsa_private_key_file=/etc/ssl/private/vsftpd.pem
ssl_enable=YES
allow_anon_ssl=NO
force_local_data_ssl=YES
force_local_logins_ssl=YES
ssl_tlsv1=YES
ssl_sslv2=NO
ssl_sslv3=NO
require_ssl_reuse=NO
ssl_ciphers=HIGH
答案1
我尝试在配置文件中添加一行。在此处打开配置：
sudo nano /etc/vsftpd.conf
并将此行放在底部：
allow_writeable_chroot=YES
然后重启服务：
sudo service vsftpd restart
这帮我修复了这个问题。
答案2
您可能遇到了与 SSL 无关的错误。
- 尝试停用 SSL (
ssl_enable=NO) - 连接您最喜欢的 FTP 客户端。
那么您可能会看到真正的错误。
这就是为什么 Francisc IB 答案与 SSL 无关的原因。
答案3
我遇到了同样的问题。另一个帖子建议不要设置允许写入_chroot=是出于安全原因，即减轻“咆哮的野兽袭击”。
环境允许写入_chroot=是意味着 vsftpd 应该允许用户的主目录可由该用户写入的情况。出于安全原因，我将用户根文件夹的权限从 777 更改为 555。
原始：drwxrwxrwx /home/ftpuser/
更改为：dr-xr-xr-x /home/ftpuser/
这使得用户的主目录不可由用户写入，因此我不必使用允许写入_chroot=是参数。这对于我的情况来说很好（并且更安全），因为我有一个预设的目录结构，并且无论如何都不希望用户在其根文件夹中创建新文件或目录。
当我将主目录切换到时，我发现了这一点/var/ftp通过local_root=[路径]参数 vsftpd 并且它无需设置就可以工作允许写入_chroot=是。此文件夹 /var/ftp 为 (755) 但归 root 所有，因此 ftpuser 不可写入。

我发现了很多令人困惑的答案。我将发布一个
/etc/vsftpd.conf
2019-09-04，我在 Ubuntu 18.04 上使用 fileZilla 作为客户端，运行完美。FTPS 部署在 EC2 实例中，该实例受非常严格的安全组监管，仅允许特定的公共 IPS 访问。
# FTPS Shim TLS configuration /etc/vsftpd.conf
# Run standalone? vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
