ftp问题(从服务器到ftp主机)

Question

我有一个网站托管在服务器上，我已经创建了一个ftp用户。现在，我试图从vps中访问ftp，但是当我给出密码时，它说我的身份验证失败了。

[root@vps ~]# ftp ftp.asifrazaprep.com
Connected to ftp.asifrazaprep.com (174.142.92.112).
220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------

这就是我在日志文件grep fpt /var/ log /messages中得到的内容。

Answer 1

3月27日17:06:14 vps proftpd28250：vps.server.com (208.111.39.5208.111.39.5) -客户端发送的命令太长，忽略

也许密码太长了？

您确实应该知道FTP服务器在哪里写入其登录和身份验证日志；这是至关重要的信息。
