‘壹’ Linux启动ftp服务器530 Permission denied解决方法
新在虚拟机下安装了linux。现在我想启动linux自带的ftp服务器:#service vsftpd start 。如果想linux启动是自动启动ftp服务器:#chkconfig vsftpd on 。
运行putty,以root身份进入,出现了报错 530 Permission denied ,感觉很奇怪,因以普通用户是可以进入的。
原因是我们 /etc/vsftpd/ftpusers 和 /etc/vsftpd/user_list 禁掉了root这个用户。这时我们需要修改这两个文件。
(1)/etc/vsftpd.user_list的默认文件(则是表示具体用户)
# vsftpd userlist
# If userlist_deny=NO, only allow users in this file
# If userlist_deny=YES (default), never allow users in this file, and
# do not even prompt for a password.
# Note that the default vsftpd pam config also checks /etc/vsftpd.ftpusers
# for users that are denied.
root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody
这时我们要在 root 前加上 # 。
(2)/etc/vsftpd.ftpusers 的默认文件(所有可以登录该FTP的用户属性)
# Users that are not allowed to login via ftp
root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody
这时我们要在 root 前加上 #
拟机装好RedHat后,准备使用filezilla连接,输入IP地址,root用户,密码,快速连接,报错:
530 Permission denied。
故障排除:
1.首先检查系统是否开启了vsftp服务,如果没有开启,先开启该服务。
方法1.setup--系统服务--自启动服务
方法2.界面设置,service vsftpd restart
2.查看配置
vsftpd的配置,配置文件中限定了vsftpd用户连接控制配置。
vsftpd.ftpusers:位于/etc目录下。它指定了哪些用户账户不能访问FTP服务器,例如root等。
vsftpd.user_list:位于/etc目录下。该文件里的用户账户在默认情况下也不能访问FTP服务器,仅当vsftpd .conf配置文件里启用userlist_enable=NO选项时才允许访问。
vsftpd.conf:位于/etc/vsftpd目录下。来自定义用户登录控制、用户权限控制、超时设置、服务器功能选项、服务器性能选项、服务器响应消息等FTP服务器的配置。
3.配置修改完成后,执行service vsftpd restart重启vsftpd服务。
‘贰’ ftp连接出现530 connection refused unknow ip address
使用的是服务器,不是虚拟主机,确保地址、用户名和密码都正确的情况下
解决方法有二:亲身经历
一、看看iis的ftp的属性里的目录安全性,是否允许你电脑的ip。
二、如果允许,ftp功能关闭再打开。
问题解决。仅供参考。
‘叁’ ftp错误代码530,这是什么意思要怎么解决
您好!FTP报错530一般会出现三种情况。
1、530 Login incorrect:这种情况,一般都是您的账号的信息有误,比如您的ftp地址,ftp账号,ftp密码以及您的端口方面有问题导致的报错这个,那么解决的方案也是非常的简单,找到您正确的信息链接,即可正常的登录。
2、530 Sorry, the maximum number of clients (3) from your host are already connected:这种情况从报错的意思是说:对不起,最大客户数(3)从你的主机已经连接,那么出现的这个原因就是您本地的ftp工具的问题,或者是您本地的连接质量不好导致的,解决的方案更换ftp工具从新链接或者是暂停关闭ftp工具 从新登陆链接即可解决。
3、530 Not logged in, home directory does not exist:出现这样的情况一般是服务器的硬盘挂掉了,或者是该用户目录不存在导致的,具体的解决方案联系空间商即可。
一般出现最多的就是以上几种情况。
‘肆’ 关于FTP连接时出现530 Login authentication failed的问题
FTP无法连接原因
检查39000/40000默认ftp端口是否开放;
检查默认FTP端口21是否开放;
如果在阿里安全组里自定义了FTP端口,同时要在宝塔控制面板中设置一致;
检查是否安装了FTP插件,图中两个都可以安装,适用不同FTP软件。
检查FTP密码是否空格
以上是我两年来总结的FTP问题,真心希望能帮到大家,如有遗漏,请高手赐教!
‘伍’ 在win7下建立FTP,用linux机器普通用户通过局域网访问win7的FTP,返回信息530 user can not log in
你的那个普通用户是不是名为administrator?
‘陆’ java调用FTP接口登陆Linux普通用户出现异常 530 Permission denied.
应该是没有登录的权限,或者就是用户名密码不对
‘柒’ Linux下设置vsftpd虚拟账号输入密码出现530错误
方法一:
登录出现 vsftpd 530 login incorrect 报错。
解决方法:
cp Path/RedHat/vsftpd.pam /etc/pam.d/ftp
path为vsftp解压缩源文件目录
这是因为我们RHEL启用了PAM,所在用到vsftp时需要用到 /etc/pam.d/ftp这个文件(默认源码安装的不会有这个文件),因此除了匿名用户外本地用户无法登录。
方法二:
在测试Checkpoint的VPN1 R6x的时候,遇到了这个错误。这说明client端跟server端的连接性是没问题。但是就是想不出为什么,还以为是用户名和口令错误呢。后来才google了一下,发现是server端的配置有问题。
检查/etc/vsftpd/user_list和/etc/ftpusers,是这个文件/etc/vsftpd/vsftpd.conf少了一行:
复制代码
代码如下:
pam_service_name=vsftpd
$ echo ‘pam_service_name=vsftpd’ >>/etc/vsftpd/vsftpd.conf
$ service vsftpd restart
530 error就消除了!
下面是更详细的方法:

#chroot_list_file=/etc/vsftpd.chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by

‘捌’ Linux中ftp连接530错误的解决方法
首先,如果正在使用vsftpd,可以先把其停掉,命令:service vsftpd stop,接下来需要编辑/etc/xinetd.d/下的`gssftp配置文件,文件内容如下:
# default: off
# description: The kerberized FTP server accepts FTP connections
# that can be authenticated with Kerberos 5.
service ftp
{
disable = yes
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/kerberos/sbin/ftpd
server_args = -l -a
log_on_failure += USERID
}
在文件中,我们要修改的内容有:
1、disable = yes 改为 disable =no ,系统默认ftp功能是无效的,修改使ftp功能生效。
2、server_args = -l -a 改为 server_args = -l。
without -a means : *enable weak authentication*
其中表示使用Kerberos 5验证机制,而一般的ftp是不支持该验证机制的。
修改完毕后,将其保存。
3、重启启动xinetd服务。请执行一下的命令(/etc/xinetd.d/):
service xinetd restart
service vsftpd restart
