[2]预防PHPDDOS的发包攻击别人的方法(iis+linux)

来源: 互联网发布时间: 2013-12-24

说下防止PHPDDOS发包的方法

代码如下:

if (eregi("ddos-udp",$read)) {
fputs($verbinden,"privmsg $Channel :ddos-udp – started udp flood – $read2[4]\n\n");
$fp = fsockopen("udp://$read2[4]", 500, $errno, $errstr, 30);
if (!$fp)
{
$fp = fsockopen("udp://$read2[4]", 500, $errno, $errstr, 30);

既然是用fsockopen()函数请求外部，那就不让他请求

php.ini里设置
allow_url_fopen = Off
如果这样他还是能发包

extension=php_sockets.dll
改成
;extension=php_sockets.dll

重启APACHE、IIS、NGINX

这样就可以防止PHP DDOS发包了

对这种攻击的处罚政策是，

Further violations will proceed with these following actions:

　　1st violation - Warning and shutdown of server. We will allow 24 hours for you to rectify the problem. 第一次是警告+关机，给24小时的时间来解决问题

　　2nd violation - Immediate reformat of server. 第二次是立即格式化服务器

　　3rd violation - Cancellation with no refund. 第三次是取消服务并不给退款

　　针对这个问题，给一个简单的描述，

　　表现特征:一打开IIS,服务器的流出带宽就用光-----就是说服务器不断向别人发包,这个情况和受到ddos攻击是不同的,Ddos是不断收到大量数据包.

　　解决办法:

　　先停止IIS，这样就暂时没法对外攻击了，然后

　　禁止上述的代码:

　　在c:\windows\php.ini里设置:

　　disable_functions =gzinflate,passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,fsocket,fsockopen

　　在c:\windows\php.ini里设其值为Off

　　allow_url_fopen = Off

　　并且:

　　;extension=php_sockets.dll

　　前面的;号一定要有,意思就是限制用sockets.dll

　　前面的;号要保留

　　然后启动IIS

　　在IP策略,或防火墙中,禁止所有udp向外发送

linux下解决办法

　　一、禁止本机对外发送UDP包

　　iptables -A OUTPUT -p udp -j DROP

　　二、允许需要UDP服务的端口(如DNS)

　　iptables -I OUTPUT -p udp --dport 53 -d 8.8.8.8 -j ACCEPT

　　绿色“53”，为DNS所需要的UDP端口，黄色“8.8.8.8”部分为DNS IP，根据您服务器的设定来定，若您不知您当前服务器使用的DNS IP，可在SSH中执行以下命令获取：

　　cat /etc/resolv.conf |grep nameserver |awk 'NR==1{print $2 }'

　　附完整iptables规则

代码如下:

　　#iptables -A INPUT -p tcp -m tcp --sport 53 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT

　　#iptables -A INPUT -p udp -m udp --sport 53 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT

　　#iptables -A OUTPUT -p tcp -m tcp --sport 1024:65535 -d 8.8.4.4 --dport 53 -m state --state NEW,ESTABLISHED -j ACCEPT

　　#iptables -A OUTPUT -p udp -m udp --sport 1024:65535 -d 8.8.8.8 --dport 53 -m state --state NEW,ESTABLISHED -j ACCEPT

　　#iptables -A OUTPUT -p udp -j REJECT

　　#/etc/rc.d/init.d/iptables save

　　# service iptables restart

　　#chkconfig iptables on

　　开放对外以及对内的 DNS端口 53

　　禁止其他全部出站的UDP 协议

　　开机启动iptables

　　另外要说明的是，上面的代码是因为我服务器使用的是谷歌的DNS来解析，我服务器端对外的访问(在服务器端上网，就需要，如果只是单纯的服务器，不进行 yum安装也可以不用)，因此我开放对8.8.4.4和8.8.8.8的访问，如果你不是设置为谷歌的DNS，那么这里要自行修改成你的DNS。使用的 DNS是什么可以用下面方法查询

利用IP安全策略下载 phpddos_jb51.rar
使用方法：
首先开始 - 运行 - gpedit.msc 找到IP安全策略
鼠标右键 - 所有任务 - 选择导入策略
最后指派策略即可

[3]IIS FTP 出现 530 User cannot log in, home Directory Inaccessible 错误处理方法

来源: 互联网发布时间: 2013-12-24

故障现象：
登陆FTP的时候提示 530 User waadmin cannot log in, home directory inaccessible.

故障原因：
FTP根目录权限不够

第一种解决方法：
把该用户所在组加个“读取”权限

或参考下面的方法
原因：
可能是在FTP服务器创建时，选择了FTP隔离用户模式。

解决方法：
在用户的ftp根目录下创建LocalUser\用户名这样的目录，因为用户登录时会自动将主目录移到这里。如果打算允许FTP站点提供匿名登录应在LocalUser目录下另建一个public的子目录LocalUser\public
