WordPress Can Be Used to Leverage Critical Ghost Flaw in Linux
|
||||
-----
|
||||
*Users are advised to apply available patches immediately*
|
||||
|
||||
|
||||
|
||||
**The vulnerability revealed this week by security researchers at Qualys, who dubbed it [Ghost](1), could be taken advantage of through WordPress or other PHP applications to compromise web servers.**
|
||||
|
||||
The glitch is a buffer overflow that can be triggered by an attacker to gain command execution privileges on a Linux machine. It is present in the glibc’s “__nss_hostname_digits_dots()” function that can be used by the “gethostbyname()” function.
|
||||
|
||||
##PHP applications can be used to exploit the glitch
|
||||
|
||||
Marc-Alexandre Montpas at Sucuri says that the problem is significant because these functions are used in plenty of software and server-level mechanism.
|
||||
|
||||
“An example of where this could be a big issue is within WordPress itself: it uses a function named wp_http_validate_url() to validate every pingback’s post URL,” which is carried out through the “gethostbyname()” function wrapper used by PHP applications, he writes in a blog post on Wednesday.
|
||||
|
||||
An attacker could use this method to introduce a malicious URL designed to trigger the vulnerability on the server side and thus obtain access to the machine.
|
||||
|
||||
In fact, security researchers at Trustwave created [proof-of-concept](2) code that would cause the buffer overflow using the pingback feature in WordPress.
|
||||
|
||||
##Multiple Linux distributions are affected
|
||||
|
||||
Ghost is present in glibc versions up to 2.17, which was made available in May 21, 2013. The latest version of glibc is 2.20, available since September 2014.
|
||||
|
||||
However, at that time it was not promoted as a security fix and was not included in many Linux distributions, those offering long-term support (LTS) in particular.
|
||||
|
||||
Among the impacted operating systems are Debian 7 (wheezy), Red Hat Enterprise Linux 6 and 7, CentOS 6 and 7, Ubuntu 12.04. Luckily, Linux vendors have started to distribute updates with the fix that mitigates the risk. Users are advised to waste no time downloading and applying them.

||||
|
||||
In order to demonstrate the flaw, Qualys has created an exploit that allowed them remote code execution through the Exim email server. The security company said that it would not release the exploit until the glitch reached its half-life, meaning that the number of the affected systems has been reduced by 50%.
|
||||
|
||||
Vulnerable application in Linux are clockdiff, ping and arping (under certain conditions), procmail, pppd, and Exim mail server.

Why Mac users don’t switch to Linux
|
||||
================================================================================
|
||||
Linux and Mac users share at least one common thing: they prefer not to use Windows. But after that the two groups part company and tend to go their separate ways. But why don’t more Mac users switch to Linux? Is there something that prevents Mac users from making the jump?
|
||||
|
||||
[Datamation took a look at these questions][1] and tried to answer them. Datamation’s conclusion was that it’s really about the applications and workflow, not the operating system:
|
||||
|
||||
> …there are some instances where replacing existing applications with new options isn’t terribly practical – both in workflow and in overall functionality. This is an area where, sadly, Apple has excelled in. So while it’s hardly “impossible” to get around these issues, they are definitely a large enough challenge that it will give the typical Mac enthusiast pause.
|
||||
>
|
||||
> But outside of Web developers, honestly, I don’t see Mac users “en masse,” seeking to disrupt their workflows for the mere idea of avoiding the upgrade to OS X Yosemite. Granted, having seen Yosemite up close – Mac users who are considered power users will absolutely find this change-up to be hideous. However, despite poor OS X UI changes, the core workflow for existing Mac users will remain largely unchanged and unchallenged.
|
||||
>
|
||||
> No, I believe Linux adoption will continue to be sporadic and random. Ever-growing, but not something that is easily measured or accurately calculated.
|
||||
|
||||
I agree to a certain extent with Datamation’s take on the importance of applications and workflows, both things are important and matter in the choice of a desktop operating system. But I think there’s something more going on with Mac users than just that. I believe that there’s a different mentality that exists between Linux and Mac users, and I think that’s the real reason why many Mac users don’t switch to Linux.
|
||||
|
||||
|
||||
|
||||
### It’s all about control for Linux users ###
|
||||
|
||||
Linux users tend to want control over their computing experience, they want to be able to change things to make them the way that they want them. One simply cannot do that in the same way with OS X or any other Apple products. With Apple you get what they give you for the most part.
|
||||
|
||||
For Mac (and iOS) users this is fine, they seem mostly content to stay within Apple’s walled garden and live according to whatever standards and options Apple gives them. But this is totally unacceptable to most Linux users. People who move to Linux usually come from Windows, and it’s there that they develop their loathing for someone else trying to define or control their computing experiences.
|
||||
|
||||
And once someone like that has tasted the freedom that Linux offers, it’s almost impossible for them to want to go back to living under the thumb of Apple, Microsoft or anyone else. You’d have to pry Linux from their cold, dead fingers before they’d accept the computing experience created for them Apple or Microsoft.
|
||||
|
||||
But you won’t find that same determination to have control among most Mac users. For them it’s mostly about getting the most out of whatever Apple has done with OS X in its latest update. They tend to adjust fairly quickly to new versions of OS X and even when unhappy with Apple’s changes they seem content to continue living within Apple’s walled garden.
|
||||
|
||||
So the need for control is a huge difference between Mac and Linux users. I don’t see it as a problem though since it just reflects the reality of two very different attitudes toward using computers.
|
||||
|
||||
### Mac users need Apple’s support mechanisms ###
|
||||
|
||||
Linux users are also different in the sense that they don’t mind getting their hands dirty by getting “under the hood” of their computers. Along with control comes the personal responsibility of making sure that their Linux systems work well and efficiently, and digging into the operating system is something that many Linux users have no problem doing.
|
||||
|
||||
When a Linux user needs to fix something, chances are they will attempt to do so immediately themselves. If that doesn’t work then they’ll seek additional information online from other Linux users and work through the problem until it has been resolved.
|
||||
|
||||
But Mac users are most likely not going to do that to the same extent. That is probably one of the reasons why Apple stores are so popular and why so many Mac users opt to buy Apple Care when they get a new Mac. A Mac user can simply take his or her computer to the Apple store and ask someone to fix it for them. There they can belly up to the Genius Bar and have their computer looked at by someone Apple has paid to fix it.
|
||||
|
||||
Most Linux users would blanche at the thought of doing such a thing. Who wants some guy you don’t even know to lay hands on your computer and start trying to fix it for you? Some Linux users would shudder at the very idea of such a thing happening.
|
||||
|
||||
So it would be hard for a Mac user to switch to Linux and suddenly be bereft of the support from Apple that he or she was used to getting in the past. Some Mac users might feel very vulnerable and uncertain if they were cut off from the Apple mothership in terms of support.
|
||||
|
||||
### Mac users love Apple’s hardware ###
|
||||
|
||||
The Datamation article focused on software, but I believe that hardware also matters to Mac users. Most Apple customers tend to love Apple’s hardware. When they buy a Mac, they aren’t just buying it for OS X. They are also buying Apple’s industrial design expertise and that can be an important differentiator for Mac users. Mac users are willing to pay more because they perceive that the overall value they are getting from Apple for a Mac is worth it.
|
||||
|
||||
Linux users, on the other hand, seem less concerned by such things. I think they tend to focus more on cost and less on the looks or design of their computer hardware. For them it’s probably about getting the most value from the hardware at the lowest cost. They aren’t in love with the way their computer hardware looks in the same way that some Mac users probably are, and so they don’t make buying decisions based on it.
|
||||
|
||||
I think both points of view on hardware are equally valid. It ultimately gets down to the needs of the individual user and what matters to them when they choose to buy or, in the case of some Linux users, build their computer. Value is the key for both groups, and each has its own perceptions of what constitutes real value in a computer.
|
||||
|
||||
Of course it is [possible to run Linux on a Mac][2], directly or indirectly via virtual machine. So a user that really liked Apple’s hardware does have the option of keeping their Mac but installing Linux on it.
|
||||
|
||||
### Too many Linux distros to choose from? ###
|
||||
|
||||
Another reason that might make it hard for a Mac user to move to Linux is the sheer number of distributions to choose from in the world of Linux. While most Linux users probably welcome the huge diversity of distros available, it could also be very confusing for a Mac user who hasn’t learned to navigate those choices.
|
||||
|
||||
Over time I think a Mac user would learn and adjust by figuring out which distribution worked best for him or her. But in the short term it might be a very daunting hurdle to overcome after being used to OS X for a long period of time. I don’t think it’s insurmountable, but it’s definitely something that is worth mentioning here.
|
||||
|
||||
Of course we do have helpful resources like [DistroWatch][3] and even my own [Desktop Linux Reviews][4] blog that can help people find the right Linux distribution. Plus there are many articles available about “the best Linux distro” and that sort of thing that Mac users can use as resources when trying to figure out the distribution they want to use.
|
||||
|
||||
But one of the reasons why Apple customers buy Macs is the simplicity and all-in-one solution that they offer in terms of the hardware and software being unified by Apple. So I am not sure how many Mac users would really want to spend the time trying to find the right Linux distribution. It might be something that puts them off really considering the switch to Linux.
|
||||
|
||||
### Mac users are apples and Linux users are oranges ###
|
||||
|
||||
I see nothing wrong with Mac and Linux users going their separate ways. I think we’re just talking about two very different groups of people, and it’s a good thing that both groups can find and use the operating system and software that they prefer. Let Mac users enjoy OS X and let Linux users enjoy Linux, and hopefully both groups will be happy and content with their computers.
|
||||
|
||||
Every once in a while a Mac user might stray over to Linux or vice versa, but for the most part I think the two groups live in different worlds and mostly prefer to stay separate and apart from one another. I generally don’t compare the two because when you get right down to it, it’s really just a case of apples and oranges.

How to limit network bandwidth on Linux
|
||||
================================================================================
|
||||
If you often run multiple networking applications on your Linux desktop, or share bandwidth among multiple computers at home, you will want to have a better control over bandwidth usage. Otherwise, when you are downloading a big file with a downloader, your interactive SSH session may become sluggish to the point where it's unusable. Or when you sync a big folder over Dropbox, your roommate may complain that video streaming at her computer gets choppy.

How To Monitor Access Point Signal Strength With wifi-linux
|
||||
================================================================================
|
||||
As a python geek I love exploring new python tools on github that target the linux users. Today I discovered a simple application written in python programming language that can be used to monitor access point signal strength.
|
||||
|
||||
I have been experimenting for about two hours with **wifi-linux** and it works great but I would like to see some unittests in the near future from the author as the command **plot** is not working on my machine and is also causing some errors.
|
||||
|
||||
### What is wifi-linux ###
|
||||
|
||||
According to the official readme.md file on author's github account wifi-linux is a very simple python script which collects RSSI information about wifi access points around you and draws graphics showing RSSI activity.
|
||||
|
||||
The author states that the program also draws RSSI activity graphic and this can be generated with the command plot but unfortunetly it is not working for me. wifi-linux supports other commands such as **bp** to add a breakpoint, **print** to print some statistics and **start changer**.
|
||||
|
||||
The wifi-linux application has the folowing dependencies:
|
||||
|
||||
- dbus-python
|
||||
- gnuplot-py
|
||||
|
||||
So first we have to install all the package dependencies for our project in order to run it in our linux machine.
|
||||
|
||||
### Install pakages required by wifi-linux ###
|
||||
|
||||
I tried to install python-dbus by using the pip tool which is used to manage python packages but it did not work and the reason for this is that pip looks for setup.py, which dbus-python doesn't have. So the following command is not going to work.
|
||||
|
||||
pip install dbus-python
|
||||
|
||||
And to make sure it does not work give it a try. It is a very high probability that you will get the following error displayed on your console.
|
||||
|
||||
IOError: [Errno 2] No such file or directory: '/tmp/pip_build_oltjano/dbus-python/setup.py'
|
||||
|
||||
How did I manage to solve this problem? It is very simple. I installed the the system package for the Python DBUS bindings using the following command.
|
||||
|
||||
sudo apt-get install python-dbus
|
||||
|
||||
The above command will work only in machines that make use of the apt-get package manager such as Debian and Ubuntu.
|
||||
|
||||
Then the second dependency we have to take care is the gnuplot-py. Download it, extract using the tar utility and then run setup.py install to install the python package.
|
||||
|
||||
First step is to download gnuplot-py.
|
||||
|
||||
wget http://prdownloads.sourceforge.net/gnuplot-py/gnuplot-py-1.8.tar.gz
|
||||
|
||||
Then use the tar utility to extract it.
|
||||
|
||||
tar xvf gnuplot-py-1.8.tar.gz
|
||||
|
||||
Then use the cd command to change directory.
|
||||
|
||||
cd gnuplot-py-1.8
|
||||
|
||||
Once there then run the following command to install the package gunplot-py on your system.
|
||||
|
||||
sudo setup.py install
|
||||
|
||||
Once the installation is finished you are ready to run the wifi-linux on your machine. Just download it and use the following command to run the script.
|
||||
|
||||
Download wifi-linux on your local machine by using the following command.
|
||||
|
||||
wget https://github.com/dixel/wifi-linux/archive/master.zip
|
||||
|
||||
Extract the master.zip archive and then use the following command to run the python script list_rsssi.py
|
||||
|
||||
python list_rssi.py
|
||||
|
||||
The following screenshot shows wifi-linux in action.
|
||||
|
||||
|
||||
|
||||
Then the command **bp** is executed to add a breakpoint like shown below.
|
||||
|
||||
|
||||
|
||||
The command **print** can be used to display stats on the console of your machine. An example of its usage is shown below.

为什么 Mac 用户不选择 Linux
|
||||
================================================================================
|
||||
Linux 与 Mac 用户至少有一个共同点：他们都不太喜欢用 Windows。但除了这点外，二者再也无法达成其他共识，只得分道扬镳。为什么 Mac 用户不选择 Linux 呢？是什么因素致使 Mac 用户做出了这种选择的？
|
||||
|
||||
[Datamation 就此问题做了一番调查][1]，并试图进行解答。Datamation 的结论是，所有原因都只归结于众多应用及工作区，而非操作系统的关系：
|
||||
|
||||
> …某些事例表明，尝试用新应用接替现有应用，并非会是很糟糕的体验 - 对工作区和实用性来说都是如此。但不幸的是，苹果在这些方面做得非常好。因此，在几乎不可能改变这些事实的情况下，想要拉拢那些 Mac忠实用户实在是很大的挑战。
|
||||
|
||||
> 不过老实来说，除了 Web 开发者，我还没见过 Mac 用户仅仅为了避免升级到 OS X Yosemite 而 “
|
||||
en masse”(法语：共同，一起) 尝试变更他们的工作区。诚然，经历过 Yosemite 更新后 - 考虑过权限的用户应该会发现这方面已经变得非常令人讨厌。并且，OS X 除了在 UI 方面几乎没有变化，针对现有 Mac 用户的核心工作区也在最大程度上保持了原样。
|
||||
|
||||
> 但，我相信 Linux 在未来将会继续保持多样化特点。Linux 会继续成长，但绝不是经过精确计量般得一成不变。
|
||||
|
||||
我大体上同意 Datamation 关于应用和工作区的重要性的结论，在选择操作系统时这两方面是必须要考虑顾及的。但我认为对 Mac 用户来说，选择 Mac 有比这两方面更重要的因素。我相信是不同的心态造就了 Linux 和 Mac 用户，并且我认为这才是为什么 Mac 用户不选择 Linux 的真实原因。
|
||||
|
||||
|
||||
|
||||
### 控制权才是 Linux 用户最看重的地方 ###
|
||||
Linux 用户倾向于控制电脑上的所有细节，他们试图作出一切能做的努力使操作系统变成他们想要的样子。但这种方式并不适用于 OS X 以及其他任何苹果的产品。如果你使用了苹果的产品，就意味着绝大多数情况下，你只能按照苹果预先设定的模式来使用它们。
|
||||
|
||||
对 Mac（以及 iOS）用户来说这没什么，因为他们似乎并不在乎生活在苹果那围墙高筑的花园里，仅仅使用那些苹果给予他们的标准和选择。但这对绝大多数 Linux 用户来说是完全不能接受的。Linux 的新用户通常来自 Windows，正是从那里，他们开始厌恶那些告诉他们什么才叫操作系统，并试图限制操作系统权限的东西的。
|
||||
|
||||
自从他们尝到使用自由的 Linux 系统所带来的甜头之后，他们就再也不会再回到苹果或者微软的监牢里去了。即使你在他们死后，把 Linux 从他们那冰冷僵硬的手指下撬出来，他们也不会接受苹果和微软那种糟糕的操作系统。
|
||||
|
||||
但绝大部分 Mac 用户不会有这样的意志和决心。对他们来说当苹果升级 OS X 时放弃他们现有的习惯方式是非常容易的。在苹果那围墙高筑的花园里，即使他们不满意苹果的变化，他们也会迅速地接受。
|
||||
|
||||
因此，对控制权的渴望是 Mac 用户与 Linux 用户的最大不同。但我并未把它视为一个问题，尽管这反映出使用电脑的两类人的截然不同的态度。
|
||||
|
||||
### Mac 用户离不开苹果的技术支持 ###
|
||||
|
||||
Linux 用户与 Mac 用户的区别也体现在 Linux 用户并不介意亲自维护自己的电脑。虽然维护电脑及控制操作系统都是很大的责任，但 Linux 用户还是愿意独自承担，愿意通过自己的力量使他们的系统工作得更棒更有效率，并且深入了解操作系统是每一位 Linux 用户都乐衷的事情。
|
||||
|
||||
当 Linux 用户遇到问题的时，他们会迅速地尝试自己来解决问题。如果这不奏效的话，他们会在网上寻找其他用户在遇到类似问题是怎么解决的，并不断进行尝试，直到问题解决。
|
||||
|
||||
但 Mac 用户却不大会这样。这也许是为什么苹果零售店如此火爆、为什么如此多的 Mac 用户在拿到新 Mac 的时候会选择购买苹果维护服务的原因。Mac 用户会很轻易得带着 TA 的电脑去苹果零售店，走进天才吧并要求苹果的工作人员为其查看和修复电脑。
|
||||
|
||||
绝大多数 Linux 用户连想都不会像这种事情。谁会愿意让一个你都不认识的家伙碰你的电脑并维修它呢？
|
||||
|
||||
因此对 Mac 用户来说，很难抛弃过去可以从苹果那里得到的技术支持，转而使用 Linux。这种选择会令某些 Mac 用户觉得自己的电脑将变得非常脆弱、容易被攻击，他们如同离开母亲怀抱的婴儿般充满了无助感。
|
||||
|
||||
### Mac 用户喜爱苹果的硬件 ###
|
||||
|
||||
Datamation 发表的文章中主要研究了软件方面的原因，但我认为硬件因素同样对 Mac 用户有很大影响。绝大部分 Mac 用户非常喜爱苹果的硬件。TA 们购买 Mac 并不仅仅是为了 OS X。苹果那精美的工艺设计也是 Mac 用户购买时着重考虑的一点。Mac 用户愿意支付高价购买电脑，因为他们认为这样绝对是物有所值的。
|
||||
|
||||
另一方面，Linux 用户似乎并不会考虑这些东西。我认为他们更偏向于在他们的电脑外观上花费较少的金钱。对他们来说，花费最少的金钱来获取尽可能好的硬件才是最重要的。他们并不像 Mac 用户一样热衷于电脑的外观，因此这一点并不是他们在购买电脑时考虑的地方。
|
||||
|
||||
我认为对于硬件的两种不同观点是没有高低之分的。这仅仅和用户的不同需求有关，仅仅会在他们购买电脑时影响他们，或者对某些 Linux 用户来说只是因为他们想要自己组装电脑而已。两种观点只是因为出发点不同、对于电脑的真正价值体现所在之处的理解不同罢了。
|
||||
|
||||
当然[在 Mac 上运行 Linux 是可能的][2]，直接运行或者间接地通过虚拟机运行。因此真心喜欢苹果硬件的 Mac 用户是可以选择在 Mac 上安装 Linux 的。
|
||||
|
||||
### Linux 发行版太多了不知道选哪个？ ###
|
||||
|
||||
另一个让 Mac 用户无法选择 Linux 的原因是：要从从众多 Linux 发行版当中选择一个实在是太困难了。在大多数 Linux 并不抗拒的多元化发行版时代，没有任何相关知识的 Mac 用户感到十分困惑。
|
||||
|
||||
我认为，随着时间的推移，Mac 用户是可以找出不适应最适合自己的发行版的。但在短时间内，尤其是在长时期得使用 OS X 之后，这是一个艰巨的任务。我不认为这个问题是无法克服的，但却有必要在这里提一下。
|
||||
|
||||
当然我们可以给 Mac 用户指明道路，推荐参考 [DistroWatch][3] 还有我们人的博客 [Desktop Linux Reviews][4]，这都有助于 Mac 用户找到正确的 Linux 发行版。再说一条，网上有很多诸如“最好的 Linux 发行版”等类似的文章，当 Mac 用户想要寻找适合自己使用的发行版时可以参考一下。
|
||||
|
||||
但有苹果顾客购买 Mac 的其中一个原因是苹果硬件软件协调统一起来的简便性和易用性。所以我不确定有多少 Mac 用户愿意花费时间找出适合自己的 Linux 发行版。也许是否要使用 Linux 确实会令 TA 们考虑一阵子了。
|
||||
|
||||
### Mac 用户是苹果，Linux 用户是橘子 ###
|
||||
|
||||
Mac 用户与 Linux 用户分道扬镳我认为并没有什么不妥。我认为我们只是在谈论两类完全不同的人群，这是一件好事，因为两类人群都在按自己四环的方式去使用操作系统和软件。让 Mac 用户和 Linux 用户各自沉浸在 OS X 和 Linux 中吧，希望他们都能高兴，都能对自己的电脑满意。
|
||||
|
||||
也许 Mac 用户会偶然走入 Linux 的世界并开始转向 Linux，但我认为绝大多数时候，两类人都愿意呆在在不同的世界并不与对方接触。通常来说我并不会随意比较二者，尤其是你已经自己拿定主意的时候，况且这只不过是选苹果还是选橘子的问题罢了。

如何用wifi-linux检测AP信号强度
|
||||
================================================================================
|
||||
作为一名python极客，我喜欢在github上发现新的针对linux用户的python工具。今天我发现了一款用python写成的用于检测AP信号强度的工具。
|
||||
|
||||
我已经在**wifi-linux**上实验了大约两个小时，并且它工作的很好但是我希望在不久的将来在作者那里看到一些单元测试，因为命令**plot**无法在我的电脑上工作，并且会导致一些问题。
|
||||
|
||||
### 什么是wifi-linux ###
|
||||
|
||||
根据github作者账号的官方的offical readme.md文件， wifi-linux是一个简单的收集你周围AP的RSSI信息的python脚本，它还会画出RSSI活动图形。
|
||||
|
||||
，这同样可以用命令plot生成，但是不幸的是，这对我不可行。wifi-linux支持其他的命令，比如**bp** 来加入一个断点，**print**会打印一些统计和**启动开关**。
|
||||
|
||||
wifi-linux程序有下面这些依赖：
|
||||
|
||||
- dbus-python
|
||||
- gnuplot-py
|
||||
|
||||
首先我们需要安装所有的包依赖以使它可以运行在我们的linux机器上。
|
||||
|
||||
### 安装wifi-linux需要的包 ###
|
||||
|
||||
我怕尝试使用python包管理工具pip安装python-dbus但是失败了，因为pip会查找setup.py，但是python-dbus中没有。因此下面的命令不工作。
|
||||
|
||||
pip install dbus-python
|
||||
|
||||
你可以试一下但是很有可能会在终端中下面的错误。
|
||||
|
||||
IOError: [Errno 2] No such file or directory: '/tmp/pip_build_oltjano/dbus-python/setup.py'
|
||||
|
||||
我该怎么解决这个问题呢？很简单，用下面命令中的系统包管理工具安装Python DBUS。
|
||||
|
||||
sudo apt-get install python-dbus
|
||||
|
||||
上面的命令只有在有apt-get包管理器的机器中才可以使用，比如Debian和Ubuntu。
|
||||
|
||||
我们要安装的第二个依赖是gnuplot-py。下载并用tar解压，接着运行setup.py来安装包。
|
||||
|
||||
第一步是下载gnuplot-py。
|
||||
|
||||
wget http://prdownloads.sourceforge.net/gnuplot-py/gnuplot-py-1.8.tar.gz
|
||||
|
||||
接着使用tar工具解压。
|
||||
|
||||
tar xvf gnuplot-py-1.8.tar.gz
|
||||
|
||||
接着使用cd命令改变目录。
|
||||
|
||||
cd gnuplot-py-1.8
|
||||
|
||||
接着运行下面的命令在你的系统中安装gnuplot-py。
|
||||
|
||||
sudo setup.py install
|
||||
|
||||
安装完成后，你就可以在你的系统中运行wifi-linux了。只需下载并用下面的命令运行脚本。
|
||||
|
||||
用下面的命令下载wifi-linux到你的机器中。
|
||||
|
||||
wget https://github.com/dixel/wifi-linux/archive/master.zip
|
||||
|
||||
解压master.zip接着使用下面的命令运行list_rsssi.py脚本。
|
||||
|
||||
python list_rssi.py
|
||||
|
||||
下面的截图说明wifi-linux在工作了。
|
||||
|
||||
|
||||
|
||||
命令**bp**用于像下面那样添加一个断点。
|
||||
|
||||
|
||||
|
||||
命令**print**可以用于显示你机器的状态。下面就是一个例子。
