通过上面命令可以查找到所依赖的安装包,直接安装glibc-2.12-1.80.el6_3.7.i686

yum install glibc-2.12-1.80.el6_3.7.i686

如果在某些特殊情况下,安装过程中有依赖关系,可以通过下面命令 yum install glibc.i686解决。

AVG ANTIVIRUS FREE - FOR LINUX帮助信息

帮助文档位于/opt/avg/av/doc/README, 囊括了安装、使用各方面帮助信息。非常有用。建议使用前先查看相关帮助信息

 
[root@localhost ~]# cat /opt/avg/av/doc/README
================================
AVG Anti-Virus for Linux/FreeBSD
Version 2013
================================
 
System requirements
-------------------
 
AVG Anti-Virus for Linux/FreeBSD requires system with following or
newer library:
- libc.so.6 (Linux)
- libc.so.7 (FreeBSD RELEASE-7.3)
  For RELEASE-8 and CURRENT the compat7x port located in /usr/ports/misc is
  needed.
- libiconv.so.3 (FreeBSD)
- for amd64 architecture the lib32 compat libraries are needed
 
For on-access scanning feature either redirfs, dazuko or dazukofs is needed.
Please follow the avgoad(1) man page for more detail description.
 
Minimum hardware requirements:
- CPU: i686 or amd64 on 800 MHz
- Mem: 512 MB, 1GB is recommended
- HDD: 500 MB of free space
 
Installation
------------
 
Download latest rpm, deb, sh or tar.gz package from http://www.avg.cz/linux and
follow these steps:
 
* Installation from RPM (Linux only)
 
# rpm -i avg2013flx-r{release}-a{vdb version}.{architecture}.rpm
 
* Installation from .deb (Linux only)
 
# dpkg -i avg2013flx-r{release}-a{vdb version}.{architecture}.deb
 
* Installation from sh
 
# chmod +x avg2013flx-r{release}-a{vdb version}.{architecture}.sh
# ./avg2013flx-r{release}-a{vdb version}.{architecture}.sh
 
* Installation from .tar.gz
 
# tar xzvf avg2013{edition}-r{release}-a{vdb version}.{architecture}.tar.gz
# cd avg2013{edition}-r{release}-a{vdb version}.{architecture}
# ./install.sh
 
where:
- edition substitutes 'flx' for the Linux version and 'ffb' for the FreeBSD version
- release substitutes the build number
- vdb version substitutes virus database version
- architecture substitutes the target cpu architecture
 
It is recommended to run 'avgsetup' helper tool after the installation.
 
 
Running AVG
-----------
 
For any action to be performed within AVG system, such as updating, scanning,
e-mail server functionality or on-access server functionality, so called AVG
daemons have to be running.
 
AVG daemons are launched automatically on system boot by init script. Later,
they can be controlled either by init script or by special avgctl command line
tool.
 
 
1) Usage of init script on Linux / FreeBSD.
 
* Linux
# /etc/init.d/avgd  {start|stop|status|restart|condrestart}
 
* FreeBSD
# /usr/local/etc/rc.d/avgd.sh {start|stop|status|restart|condrestart}
 
2) Usage of avgctl command line tool
 
# avgctl --start[=component]      Starts AVG or specified component.
# avgctl --stop[=component]       Stops AVG or specified component. 
# avgctl --stat[=component]       Shows statistics of AVG or specified component.
# avgctl --restart[=component]    Restarts AVG or specified component.
# avgctl --reset=component        Resets statistics of specified component.
 
For more detailed information please refer to the respective man page or avgctl help.
 
Description
-----------
 
Avg functions are secured by several daemons that are managed via command-line.  
 
DAEMONS:
   avgd       -- general AVG daemon; starts first, manages other AVG daemons
   avgavid    -- AVI daemon; loads AVI into shared memory
   avgsched   -- scheduler for planning periodic events (update etc.) 
   avgtcpd    -- e-mail scanning daemon; supports SMTP, AVG, and Milter protocol
   avgspamd   -- anti-spam daemon
   avgscand   -- anti-virus daemon
   avgupd     -- update daemon
   avgoad     -- on-access daemon
 
COMMAND-LINES:
   avgctl     -- basic control of AVG product, such as launching, stopping,
                 restarting, and getting statistics from running daemons
   avgcfgctl  -- can get and set configurations values
   avgscan    -- launch on-demand scan of requested path
   avgupdate  -- run virus database update or program update via avgupd with
                 specified parameters
   avgvvctl   -- AVG virus vault control utility
   avgdiag    -- tool for sending problem reports to crash analysis portal
   avgevtlog  -- tool for reading/managing AVG event log
   avgsetup   -- helper tool for basic integration with mail/file server
 
For more detailed information please refer to the respective man page.
 
AVG process tree (might look different in your configuration):
 
/opt/avg/av/bin//avgd 
 \--- /opt/avg/av/bin/avgavid
 \--- /opt/avg/av/bin/avgtcpd
 |     \--- /opt/avg/av/bin/avgscand -c 3
 \--- /opt/avg/av/bin/avgspamd
 \--- /opt/avg/av/bin/avgoad
 |     \--- /opt/avg/av/bin/avgscand -c 4
 \--- /opt/avg/av/bin/avgsched
 
If update is running:
 \--- /opt/avg/av/bin/avgupd
/bin/login --     
  \--- -bash
        \--- /opt/avg/av/bin/avgupdate
 
If on-demand scan is running:
/bin/login --     
 \--- -bash
       \--- /opt/avg/av/bin/avgscan /
             \--- /opt/avg/av/bin/avgscand -c 10
 
 
 
Diagnostic and system report
----------------------------
 
In case of troubles with any AVG Technologies product, gathering of specific
data is being performed by the avgdiag utility.
 
When sending data manually, it is very important to attach a detailed
description of this particular problem and to specify it with "-d, --dsc=<file>"
switches.  It is also good to make sure that AVG customer support assigns a
specific ID to your report, which eventually facilitates its identification
(this is being defined by "-i, --id=<id>" switches).
 
Automatic reporting of AVG processes crashes is turned off by default; if you
want to enable this function, please add AVG_DIAG option to your
/opt/avg/av/cfg/dump.ini file.  For example:
 
"actions = GDB_DUMP CRASH INFO AVG_DIAG"
 
This configuration ensures that should any AVG process crash, an adequate report
will be immediately sent to AVG Technologies.
 
For more detailed information please refer to the man page of avgdump, avgdiag
help or /opt/avg/av/doc/README.avgdiag document.

This product may use any of the 3rd party software which appropriate

AVG ANTIVIRUS FREE - FOR LINUX 的扫描速率非常之快,消耗的资源也比较少。至于查杀能力如何呢,暂时还没有看到权威的评测的资料。暂时不能做过多评论。

在上篇文章“记一次Linux服务器上查杀木马经历”里面,我介绍了使用ClamAV清理了木马程序,当时以为清理干净了,但是过了一天后,使用NetHogs又发现可疑进程。使用ClamAV查杀清理又发现感染了Linux.BackDoor.Gates,查杀完成后,重启系统后到目前为止没有发现任何异常情况。后来我在这台Linux服务器安装了AVG Anti-Virus,扫描倒是非常快,比ClamAV的速度要快出几个等级,但是查杀能力无法验证。倒是扫出了很多Linux.BackDoor.Gates创建的一些链接。ClamAV倒是没有扫出这些。 

clip_image009

[root@LNX17 ~]# ls -lrt /etc/rc.d/rc5.d/S97DbSecurityMdt

[root@LNX17 ~]# ls -lrt /etc/init.d/DbSecurityMdt
ls: cannot access /etc/init.d/DbSecurityMdt: No such file or directory
[root@LNX17 ~]#


清理这些链接后,已经过了几天,再也没有发现异常情况,从网络发包、收包情况看,已经没有任何异常情况。

rm -f /etc/rc.d/rc5.d/S97DbSecurityMdt 
rm -f /etc/rc.d/rc5.d/S99selinux

rm -f /etc/rc.d/rc2.d/S97DbSecurityMdt 
rm -f /etc/rc.d/rc2.d/S99selinux 


关于这台服务器是如何挂马的呢? 我也在思考,奈何能力有限,无法确认一些猜测(个人猜测是利用Tomcat漏洞挂马)。关于Linux安全管理方面,个人觉得杀毒软件只是根治病毒木马的一种手段。我们需要从很多方面(安全补丁更新、正确配置、防火墙配置……)去预防、监控才能真正的确保系统的安全。
