如何将ClamAV集成到PureFTPd中进行病毒扫描在OpenSUSE 11.3上

如何将ClamAV集成到PureFTPd中,以便在OpenSUSE 11.3上进行病毒扫描

本教程将介绍如何将ClamAV集成到PureFTPd中,以便在OpenSUSE 11.3系统上进行病毒扫描。 最后,每当通过PureFTPd上传文件时,ClamAV将检查文件并将其删除,如果它是恶意软件。

我不会保证这将为您工作!

1初步说明

您应该在OpenSUSE 11.3服务器上安装一个工作的PureFTPd,例如本教程所示: 使用PureFTPd和MySQL进行虚拟托管(包括配额和带宽管理)在OpenSUSE 11.3上

2安装ClamAV

ClamAV可以安装如下:

yast2 -i clamav clamav-db

接下来,我们为clamd创建系统启动链接并启动它:

chkconfig --add clamd
/etc/init.d/clamd start

3配置PureFTPd

首先,我们打开/etc/pure-ftpd/pure-ftpd.conf并将Umask设置为133:022 (以便clamdscan具有读取上传文件的正确权限)和CallUploadScriptyes

vi /etc/pure-ftpd/pure-ftpd.conf
[...]
# File creation mask. <umask for files>:<umask for dirs> .
# 177:077 if you feel paranoid.

Umask                       133:022
[...]
# If your pure-ftpd has been compiled with pure-uploadscript support,
# this will make pure-ftpd write info about new uploads to
# /var/run/pure-ftpd.upload.pipe so pure-uploadscript can read it and
# spawn a script to handle the upload.

CallUploadScript yes
[...]

接下来,我们创建文件/etc/pure-ftpd/clamav_check.sh (每当通过PureFTPd上传文件时,它将调用/ usr / bin / clamdscan)...

vi /etc/pure-ftpd/clamav_check.sh
#!/bin/sh
/usr/bin/clamdscan --remove --quiet --no-summary "$1"

...并使其可执行:

chmod 755 /etc/pure-ftpd/clamav_check.sh

现在我们启动pure-uploadscript程序作为守护进程,每当通过PureFTPd上传文件时,它将会调用我们的/etc/pure-ftpd/clamav_check.sh脚本:

pure-uploadscript -B -r /etc/pure-ftpd/clamav_check.sh

当然,你不想在启动系统时手动启动守护进程 - 因此我们打开/etc/init.d/boot.local ...

vi /etc/init.d/boot.local

...并将/ usr / sbin / pure-uploadscript -b -r /etc/pure-ftpd/clamav_check.sh添加到其中 - 如下所示:

#! /bin/sh

#

#         Burchard Steinbild, 1996
#
# /etc/init.d/boot.local
#
# script with local commands to be executed from init on system startup
#
# Here you should add things, that should happen directly after booting
# before we're going to the first run level.
#

/usr/sbin/pure-uploadscript -B -r /etc/pure-ftpd/clamav_check.sh

最后我们重新启动PureFTPd:

/etc/init.d/pure-ftpd restart

而已! 现在每当有人尝试通过PureFTPd将恶意软件上传到您的服务器时,“坏”文件将被默认删除。
