Dnsmasq

[root@dnsmaster ~]# yum install -y dnsmasq
[root@dnsmaster ~]# systemctl start dnsmasq.service
[root@dnsmaster ~]# systemctl  stop  firewalld --临时关闭防火墙 
[root@dnsmaster ~]# systemctl  disable  firewalld  --永久关闭防火墙
[root@dnsmaster ~]# setenforce 0   --临时关闭
[root@dnsmaster ~]# vim /etc/selinux/config
SELINUX=disabled        --将enforcing改为disabled
[root@dnsmaster ~]# reboot     --重启系统永久生效
[root@dnsmaster ~]# vim /etc/dnsmasq.conf
resolv-file=/etc/resolv.dnsmasq.conf    //dnsmasq 会从这个文件中寻找上游dns服务器
strict-order                               //去掉前面的#
addn-hosts=/etc/dnsmasq.hosts              //在这个目里面添加记录
listen-address=127.0.0.1,192.168.1.123     //监听地址
resolv-file=/etc/resolv.conf
strict-order
listen-address=192.168.153.128
address=/demon.com/192.168.153.128
server=114.114.114.114
bogus-nxdomain=114.114.114.114

对参数的解释
resolve-file     定义dnsmasq从哪里获取上游DNS服务器的地址, 默认是从/etc/resolv.conf获取。
strict-order     表示严格按照resolv-file文件中的顺序从上到下进行DNS解析,直到第一个解析成功为止。
listen-address     定义dnsmasq监听的地址,默认是监控本机的所有网卡上。局域网内主机若要使用dnsmasq服务时,指定本机的IP地址。
address        启用泛域名解析,即自定义解析a记录,如下配置为demon.com这个域名:
*address=/demon.com/127.0.0.1  #访问demon.com时的所有域名都会被解析成127.0.0.1*
bogus-nxdomain     为防止DNS污染,使用参数定义的DNS解析的服务器。注意:如果是阿里云服务器上配置dnsmasq要启用此项。
server       指定dnsmasq程序使用哪个DNS服务器进行解析。对于不同的网站可以使用不同的域名对应解析如下配置
*server=/google.com/8.8.8.8    #表示对于google的服务,使用谷歌的DNS解析。*

Ubuntu利用IPSET批量封禁IP

ipset create xxx hash:net 
ipset -N cnip hash:net

ipset create blacklist hash:net maxelem 1000000 #黑名单
ipset create whitelist hash:net maxelem 1000000 #白名单

ipset add blacklist 10.60.10.xx

wget -P . http://www.ipdeny.com/ipblocks/data/countries/cn.zone

for i in $(cat /root/cn.zone ); do ipset -A cnip $i; done

将ipset规则保存到文件
ipset save blacklist -f blacklist.txt
ipset save whitelist -f whitelist.txt

删除ipset
ipset destroy blacklist
ipset destroy whitelist

允许cnip访问端口
-A INPUT -p tcp -m set --match-set cnip src -m tcp --dport 51801:51809 -j ACCEPT

VSFTPD被动模式

防火墙配置
 在iptables-config 最下面增加
 IPTABLES_MODULES="ip_conntrack_ftp"
 IPTABLES_MODULES="ip_nat_ftp"

在iptables内增加:
 -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
 -A INPUT -p tcp --dport 29151:29171 -j ACCEPT

用户设置:
 useradd -d /home/source/UI -s /sbin/nologin UiFtp
 passwd UiFtp
 chown -R UiFtp:root /home/source/UI
 或
 chown -R 用户名.组 /home/source/App

配置vsftp.conf,末尾加入
 pam_service_name=vsftpd
 userlist_enable=YES
 tcp_wrappers=YES
 listen_port=30941
 pasv_enable=YES
 pasv_min_port=29151
 pasv_max_port=29170

配置chroot_list
