Debian
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
    apt -y install libclamav-dev  libip4tc-dev libcurl4-openssl-dev    #(或者libcurl4-gnutls-dev)  
    apt -y install libsystemd-dev libjson-c-dev libpcre2-dev clamav-freshclam
    apt -y install libltdl-dev libmspack-dev
    freshclam  # 更新病毒库(必要)
    

    Debian系统使用libiptc库需要nftables切换到iptables
    Switching to the legacy version:(切换到 iptables)
    update-alternatives --set iptables /usr/sbin/iptables-legacy
    update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
    update-alternatives --set arptables /usr/sbin/arptables-legacy
    update-alternatives --set ebtables /usr/sbin/ebtables-legacy
```

```
Centos 7
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
    yum install clamav clamav-update clamav-lib clamav-devel json-c-devel pcre2-devel
    yum install iptables-devel libcurl-devel 
    yum install systemd-devel libtool-ltdl-devel libmspack-devel
    
    yum -y install centos-release-scl
    yum -y install devtoolset-11-gcc
    source /opt/rh/devtoolset-11/enable                                 #临时
    echo "source /opt/rh/devtoolset-11/enable" >> /etc/profile          #永久
    
    mv /etc/cron.d/clamav-update /root
    sed -i "s/DatabaseMirror .*/DatabaseMirror clamavdb.c3sl.ufpr.br/g" /etc/freshclam.conf
    freshclam  # 更新病毒库(必要)
```




```
用法
cd /root
git clone https://git.aixiao.me/aixiao/denyhosts  
cd denyhosts  
make clean  
make libclamav_rust  
make libclamav  
make all  
或  
    bash build.sh  

启动:
./rhost -d -r / --exclude-dir="^/sys|^/dev|^/proc|^/opt/infected|^/root|^/home" --move=/opt/infected --max-filesize 1024M -l clamscan.log    # 用户指定参数,后台运行并扫描病毒

./rhost -d  # 后台运行读取配置文件参数

./rhost     # 只处理非法攻击


关闭
killall rhost


```
