如何使用ftp(/ usr/bin/ftp)匿名登录？

Question

我正在尝试连接到允许匿名访问的FTP服务器,但我不知道如何指定执行此操作所需的相应用户名/密码.

我尝试使用匿名/匿名作为用户/传递没有运气,以及空字符串和两者的各种组合等.

它必须是我想念的简单东西,我可以使用连接 curl ftp://server/

使用python:

stu@sente ~ $ cat - | python
import ftplib
ftp = ftplib.FTP("ftp.server")
ftp.set_debuglevel(2)
ftp.connect()
ftp.login()
list = ftp.nlst()
ftp.close()
print "\n", " ".join(list)

Answer 1

匿名ftp登录通常是用户名'匿名',用户的电子邮件地址作为密码.某些服务器会解析密码以确保其看起来像电子邮件地址.

User:  anonymous
Password:  anonymous@domain.com

Answer 2

RFC 1635:如何使用匿名FTP涵盖匿名FTP使用:

什么是匿名FTP？

匿名FTP是存档站点允许对其信息档案进行一般访问的一种方法.这些网站创建了一个名为"匿名"的特殊帐户.

...

传统上,这个特殊的匿名用户帐户接受任何字符串作为密码,尽管通常使用密码"guest"或一个人的电子邮件(e-mail)地址.一些存档站点现在明确要求用户的电子邮件地址,并且不允许使用"访客"密码登录.提供电子邮件地址是一种礼貌,允许存档网站运营商了解谁在使用他们的服务.

但这些是一般性建议.每个FTP服务器都有自己的指南.
