众所周知，`ping` 命令可以用来检查目标主机是否可达。使用 `ping` 命令的时候，会发送一个 ICMP Echo 请求，通过目标主机的响应与否来确定目标主机的状态。如果你经常使用 `ping` 命令，你可以尝试一下 `prettyping`。Prettyping 只是将一个标准的 ping 工具增加了一层封装，在运行标准 ping 命令的同时添加了颜色和 unicode 字符解析输出，所以它的输出更漂亮紧凑、清晰易读。它是用 `bash` 和 `awk` 编写的免费开源工具，支持大部分类 Unix 操作系统，包括 GNU/Linux、FreeBSD 和 Mac OS X。Prettyping 除了美化 ping 命令的输出，还有很多值得注意的功能。

How to Use the Netplan Network Configuration Tool on Linux
|
||||
======
|
||||
|
||||
|
||||
|
||||
For years Linux admins and users have configured their network interfaces in the same way. For instance, if you’re a Ubuntu user, you could either configure the network connection via the desktop GUI or from within the /etc/network/interfaces file. The configuration was incredibly easy and never failed to work. The configuration within that file looked something like this:
|
||||
|
||||
```
|
||||
auto enp10s0
|
||||
|
||||
iface enp10s0 inet static
|
||||
|
||||
address 192.168.1.162
|
||||
|
||||
netmask 255.255.255.0
|
||||
|
||||
gateway 192.168.1.100
|
||||
|
||||
dns-nameservers 1.0.0.1,1.1.1.1
|
||||
|
||||
```
|
||||
|
||||
Save and close that file. Restart networking with the command:
|
||||
|
||||
```
|
||||
sudo systemctl restart networking
|
||||
|
||||
```
|
||||
|
||||
Or, if you’re not using a non-systemd distribution, you could restart networking the old fashioned way like so:
|
||||
|
||||
```
|
||||
sudo /etc/init.d/networking restart
|
||||
|
||||
```
|
||||
|
||||
Your network will restart and the newly configured interface is good to go.
|
||||
|
||||
That’s how it’s been done for years. Until now. With certain distributions (such as Ubuntu Linux 18.04), the configuration and control of networking has changed considerably. Instead of that interfaces file and using the /etc/init.d/networking script, we now turn to [Netplan][1]. Netplan is a command line utility for the configuration of networking on certain Linux distributions. Netplan uses YAML description files to configure network interfaces and, from those descriptions, will generate the necessary configuration options for any given renderer tool.
|
||||
|
||||
I want to show you how to use Netplan on Linux, to configure a static IP address and a DHCP address. I’ll be demonstrating on Ubuntu Server 18.04. I will give you one word of warning, the .yaml files you create for Netplan must be consistent in spacing, otherwise they’ll fail to work. You don’t have to use a specific spacing for each line, it just has to remain consistent.
|
||||
|
||||
### The new configuration files
|
||||
|
||||
Open a terminal window (or log into your Ubuntu Server via SSH). You will find the new configuration files for Netplan in the /etc/netplan directory. Change into that directory with the command cd /etc/netplan. Once in that directory, you will probably only see a single file:
|
||||
|
||||
```
|
||||
01-netcfg.yaml
|
||||
|
||||
```
|
||||
|
||||
You can create a new file or edit the default. If you opt to edit the default, I suggest making a copy with the command:
|
||||
|
||||
```
|
||||
sudo cp /etc/netplan/01-netcfg.yaml /etc/netplan/01-netcfg.yaml.bak
|
||||
|
||||
```
|
||||
|
||||
With your backup in place, you’re ready to configure.
|
||||
|
||||
### Network Device Name
|
||||
|
||||
Before you configure your static IP address, you’ll need to know the name of device to be configured. To do that, you can issue the command ip a and find out which device is to be used (Figure 1).
|
||||
|
||||
![netplan][3]
|
||||
|
||||
Figure 1: Finding our device name with the ip a command.
|
||||
|
||||
[Used with permission][4]
|
||||
|
||||
I’ll be configuring ens5 for a static IP address.
|
||||
|
||||
### Configuring a Static IP Address
|
||||
|
||||
Open the original .yaml file for editing with the command:
|
||||
|
||||
```
|
||||
sudo nano /etc/netplan/01-netcfg.yaml
|
||||
|
||||
```
|
||||
|
||||
The layout of the file looks like this:
|
||||
|
||||
network:
|
||||
|
||||
Version: 2
|
||||
|
||||
Renderer: networkd
|
||||
|
||||
ethernets:
|
||||
|
||||
DEVICE_NAME:
|
||||
|
||||
Dhcp4: yes/no
|
||||
|
||||
Addresses: [IP/NETMASK]
|
||||
|
||||
Gateway: GATEWAY
|
||||
|
||||
Nameservers:
|
||||
|
||||
Addresses: [NAMESERVER, NAMESERVER]
|
||||
|
||||
Where:
|
||||
|
||||
* DEVICE_NAME is the actual device name to be configured.
|
||||
|
||||
* yes/no is an option to enable or disable dhcp4.
|
||||
|
||||
* IP is the IP address for the device.
|
||||
|
||||
* NETMASK is the netmask for the IP address.
|
||||
|
||||
* GATEWAY is the address for your gateway.
|
||||
|
||||
* NAMESERVER is the comma-separated list of DNS nameservers.
|
||||
|
||||
|
||||
|
||||
|
||||
Here’s a sample .yaml file:
|
||||
|
||||
```
|
||||
network:
|
||||
|
||||
version: 2
|
||||
|
||||
renderer: networkd
|
||||
|
||||
ethernets:
|
||||
|
||||
ens5:
|
||||
|
||||
dhcp4: no
|
||||
|
||||
addresses: [192.168.1.230/24]
|
||||
|
||||
gateway4: 192.168.1.254
|
||||
|
||||
nameservers:
|
||||
|
||||
addresses: [8.8.4.4,8.8.8.8]
|
||||
|
||||
```
|
||||
|
||||
Edit the above to fit your networking needs. Save and close that file.
|
||||
|
||||
Notice the netmask is no longer configured in the form 255.255.255.0. Instead, the netmask is added to the IP address.
|
||||
|
||||
### Testing the Configuration
|
||||
|
||||
Before we apply the change, let’s test the configuration. To do that, issue the command:
|
||||
|
||||
```
|
||||
sudo netplan try
|
||||
|
||||
```
|
||||
|
||||
The above command will validate the configuration before applying it. If it succeeds, you will see Configuration accepted. In other words, Netplan will attempt to apply the new settings to a running system. Should the new configuration file fail, Netplan will automatically revert to the previous working configuration. Should the new configuration work, it will be applied.
|
||||
|
||||
### Applying the New Configuration
|
||||
|
||||
If you are certain of your configuration file, you can skip the try option and go directly to applying the new options. The command for this is:
|
||||
|
||||
```
|
||||
sudo netplan apply
|
||||
|
||||
```
|
||||
|
||||
At this point, you can issue the command ip a to see that your new address configurations are in place.
|
||||
|
||||
### Configuring DHCP
|
||||
|
||||
Although you probably won’t be configuring your server for DHCP, it’s always good to know how to do this. For example, you might not know what static IP addresses are currently available on your network. You could configure the device for DHCP, get an IP address, and then reconfigure that address as static.
|
||||
|
||||
To use DHCP with Netplan, the configuration file would look something like this:
|
||||
|
||||
```
|
||||
network:
|
||||
|
||||
version: 2
|
||||
|
||||
renderer: networkd
|
||||
|
||||
ethernets:
|
||||
|
||||
ens5:
|
||||
|
||||
Addresses: []
|
||||
|
||||
dhcp4: true
|
||||
|
||||
optional: true
|
||||
|
||||
```
|
||||
|
||||
Save and close that file. Test the file with:
|
||||
|
||||
```
|
||||
sudo netplan try
|
||||
|
||||
```
|
||||
|
||||
Netplan should succeed and apply the DHCP configuration. You could then issue the ip a command, get the dynamically assigned address, and then reconfigure a static address. Or, you could leave it set to use DHCP (but seeing as how this is a server, you probably won’t want to do that).
|
||||
|
||||
Should you have more than one interface, you could name the second .yaml configuration file 02-netcfg.yaml. Netplan will apply the configuration files in numerical order, so 01 will be applied before 02. Create as many configuration files as needed for your server.
|
||||
|
||||
### That’s All There Is
|
||||
|
||||
Believe it or not, that’s all there is to using Netplan. Although it is a significant change to how we’re accustomed to configuring network addresses, it’s not all that hard to get used to. But this style of configuration is here to stay… so you will need to get used to it.

多年以来 Linux 管理员和用户们使用相同的方式配置他们的网络接口。例如，如果你是 Ubuntu 用户，你能够用桌面 GUI 配置网络连接，也可以在 /etc/network/interfaces 文件里配置。配置相当简单且从未失败。在文件中配置看起来就像这样：
|
||||
|
||||
```
|
||||
auto enp10s0
|
||||
|
||||
iface enp10s0 inet static
|
||||
|
||||
address 192.168.1.162
|
||||
|
||||
netmask 255.255.255.0
|
||||
|
||||
gateway 192.168.1.100
|
||||
|
||||
dns-nameservers 1.0.0.1,1.1.1.1
|
||||
```
|
||||
|
||||
保存并关闭文件。使用命令重启网络：
|
||||
|
||||
```
|
||||
sudo systemctl restart networking
|
||||
```
|
||||
|
||||
或者，如果你使用不带systemd 的发行版，你可以通过老办法来重启网络：
|
||||
|
||||
```
|
||||
sudo /etc/init.d/networking restart
|
||||
```
|
||||
|
||||
你的网络将会重新启动，新的配置将会生效。
|
||||
|
||||
这就是多年以来的做法。但是现在，在某些发行版上（例如 Ubuntu Linux 18.04），网络的配置与控制发生了很大的变化。不需要那个 interfaces 文件和 /etc/init.d/networking 脚本，我们现在转向使用 [Netplan][1]。Netplan 是一个在某些 Linux 发行版上配置网络连接的命令行工具。Netplan 使用 YAML 描述文件来配置网络接口，然后，通过这些描述为任何给定的呈现工具生成必要的配置选项。
|
||||
|
||||
我将向你展示如何在 Linux 上使用 Netplan 配置静态 IP 地址和 DHCP 地址。我会在 Ubuntu Server 18.04 上演示。有句忠告，你创建的 .yaml 文件中的间距必须保持一致，否则将会失败。你不用为每行使用特定的间距，只需保持一致就行了。
|
||||
|
||||
### 新的配置文件
|
||||
|
||||
打开终端窗口（或者通过 SSH 登录进 Ubuntu 服务器）。你会在 /etc/netplan 文件夹下发现 Netplan 的新配置文件。使用 cd/etc/netplan 命令进入到那个文件夹下。一旦进到了那个文件夹，也许你就能够看到一个文件：
|
||||
|
||||
```
|
||||
01-netcfg.yaml
|
||||
```
|
||||
|
||||
你可以创建一个新的文件或者是编辑默认文件。如果你打算修改默认文件，我建议你先做一个备份：
|
||||
|
||||
```
|
||||
sudo cp /etc/netplan/01-netcfg.yaml /etc/netplan/01-netcfg.yaml.bak
|
||||
```
|
||||
|
||||
备份好后，就可以开始配置了。
|
||||
|
||||
### 网络设备名称
|
||||
|
||||
在你开始配置静态 IP 之前，你需要知道设备名称。要做到这一点，你可以使用命令 ip a，然后找出哪一个设备将会被用到（图 1）。
|
||||
|
||||
![netplan][3]
|
||||
|
||||
图 1：使用 ip a 命令找出设备名称
|
||||
|
||||
[Used with permission][4] （译注：这是什么鬼？）
|
||||
|
||||
我将为 ens5 配置一个静态的 IP。
|
||||
|
||||
### 配置静态 IP 地址
|
||||
|
||||
使用命令打开原来的 .yaml 文件：
|
||||
|
||||
```
|
||||
sudo nano /etc/netplan/01-netcfg.yaml
|
||||
```
|
||||
|
||||
文件的布局看起来就像这样：
|
||||
|
||||
network:
|
||||
|
||||
Version: 2
|
||||
|
||||
Renderer: networkd
|
||||
|
||||
ethernets:
|
||||
|
||||
DEVICE_NAME:
|
||||
|
||||
Dhcp4: yes/no
|
||||
|
||||
Addresses: [IP/NETMASK]
|
||||
|
||||
Gateway: GATEWAY
|
||||
|
||||
Nameservers:
|
||||
|
||||
Addresses: [NAMESERVER, NAMESERVER]
|
||||
|
||||
其中：
|
||||
|
||||
* DEVICE_NAME 是需要配置设备的实际名称。
|
||||
|
||||
* yes/no 代表是否启用 dhcp4。
|
||||
|
||||
* IP 是设备的 IP 地址。
|
||||
|
||||
* NETMASK 是 IP 地址的掩码。
|
||||
|
||||
* GATEWAY 是网关的地址。
|
||||
|
||||
* NAMESERVER 是由逗号分开的 DNS 服务器列表。
|
||||
|
||||
这是一份 .yaml 文件的样例：
|
||||
|
||||
```
|
||||
network:
|
||||
|
||||
version: 2
|
||||
|
||||
renderer: networkd
|
||||
|
||||
ethernets:
|
||||
|
||||
ens5:
|
||||
|
||||
dhcp4: no
|
||||
|
||||
addresses: [192.168.1.230/24]
|
||||
|
||||
gateway4: 192.168.1.254
|
||||
|
||||
nameservers:
|
||||
|
||||
addresses: [8.8.4.4,8.8.8.8]
|
||||
```
|
||||
|
||||
编辑上面的文件以达到你想要的效果。保存并关闭文件。
|
||||
|
||||
注意，掩码已经不用再配置为 255.255.255.0 这种形式。取而代之的是，掩码已被添加进了 IP 地址中。
|
||||
|
||||
### 测试配置
|
||||
|
||||
在应用改变之前，让我们测试一下配置。为此，使用命令：
|
||||
|
||||
```
|
||||
sudo netplan try
|
||||
```
|
||||
|
||||
上面的命令会在应用配置之前验证其是否有效。如果成功，你就会看到配置被接受。换句话说，Netplan 会尝试将新的配置应用到运行的系统上。如果新的配置失败了，Netplan 会自动地恢复到之前使用的配置。成功后，新的配置就会被使用。
|
||||
|
||||
### 应用新的配置
|
||||
|
||||
如果你确信配置文件没有问题，你就可以跳过测试环节并且直接使用新的配置。它的命令是：
|
||||
|
||||
```
|
||||
sudo netplan apply
|
||||
```
|
||||
|
||||
此时，你可以使用 ip a 看看新的地址是否正确。
|
||||
|
||||
### 配置 DHCP
|
||||
|
||||
虽然你可能不会配置 DHCP 服务，但通常还是知道比较好。例如，你也许不知道网络上当前可用的静态 IP 地址是多少。你可以为设备配置 DHCP，获取到 IP 地址，然后将那个地址重新配置为静态地址。
|
||||
|
||||
在 Netplan 上使用 DHCP，配置文件看起来就像这样：
|
||||
|
||||
```
|
||||
network:
|
||||
|
||||
version: 2
|
||||
|
||||
renderer: networkd
|
||||
|
||||
ethernets:
|
||||
|
||||
ens5:
|
||||
|
||||
Addresses: []
|
||||
|
||||
dhcp4: true
|
||||
|
||||
optional: true
|
||||
```
|
||||
|
||||
保存并退出。用下面命令来测试文件：
|
||||
|
||||
```
|
||||
sudo netplan try
|
||||
```
|
||||
|
||||
Netplan 应该会成功配置 DHCP 服务。这时你可以使用 ip a 命令得到动态分配的地址，然后重新配置静态地址。或者，你可以直接使用 DHCP 分配的地址（但看看这是一个服务器，你可能不想这样做）。
|
||||
|
||||
也许你有不只一个的网络接口，你可以命名第二个 .yaml 文件为 02-netcfg.yaml 。Netplan 会按照数字顺序应用配置文件，因此 01 会在 02 之前使用。根据你的需要创建多个配置文件。
|
||||
|
||||
### 就是这些了
|
||||
|
||||
不管你信不信，那些就是所有关于使用 Netplan 的东西了。虽然它对于我们习惯性的配置网络地址来说是一个相当大的改变，但并不是所有人都用的惯。但这种配置方式值得一提...因此你会适应的。

How To List An Available Package Groups In Linux
|
||||
如何在 Linux 中列出可用的软件包组
|
||||
======
|
||||
As we know, if we want to install any packages in Linux we need to use the distribution package manager to get it done.
|
||||
我们知道，如果想要在 Linux 中安装软件包，可以使用软件包管理器来进行安装。由于系统管理员需要频繁用到软件包管理器，所以它是 Linux 当中的一个重要工具。
|
||||
|
||||
Package manager is playing major role in Linux as this used most of the time by admin.
|
||||
但是如果想一次性安装一个软件包组，在 Linux 中有可能吗？又如何通过命令去实现呢？
|
||||
|
||||
If you would like to install group of package in one shot what would be the possible option.
|
||||
在 Linux 中确实可以用软件包管理器来达到这样的目的。很多软件包管理器都有这样的选项来实现这个功能，但就我所知，`apt` 或 `apt-get` 软件包管理器却并没有这个选项。因此对基于 Debian 的系统，需要使用的命令是 `tasksel`，而不是 `apt`或 `apt-get` 这样的官方软件包管理器。
|
||||
|
||||
Is it possible in Linux? if so, what would be the command for it.
|
||||
在 Linux 中安装软件包组有很多好处。对于 LAMP 来说，安装过程会包含多个软件包，但如果安装软件包组命令来安装，只安装一个包就可以了。
|
||||
|
||||
Yes, this can be done in Linux by using the package manager. Each package manager has their own option to perform this task, as i know apt or apt-get package manager doesn’t has this option.
|
||||
当你的团队需要安装 LAMP，但不知道其中具体包含哪些软件包，这个时候软件包组就派上用场了。软件包组是 Linux 系统上一个很方便的工具，它能让你轻松地完成一组软件包的安装。
|
||||
|
||||
For Debian based system we need to use tasksel command instead of official package managers called apt or apt-get.
|
||||
软件包组是一组用于公共功能的软件包，包括系统工具、声音和视频。 安装软件包组的过程中，会获取到一系列的依赖包，从而大大节省了时间。
|
||||
|
||||
What is the benefit if we install group of package in Linux? Yes, there is lot of benefit is available in Linux when we install group of package because if you want to install LAMP separately we need to include so many packages but that can be done using single package when we use group of package command.

### 如何在 CentOS/RHEL 系统上列出可用的软件包组
|
||||
|
||||
Group option is a handy tool for Linux systems which will install Group of Software in a single click on your system without headache.
|
||||
RHEL 和 CentOS 系统使用的是 RPM 软件包，因此可以使用 `yum` 软件包管理器来获取相关的软件包信息。
|
||||
|
||||
A package group is a collection of packages that serve a common purpose, for instance System Tools or Sound and Video. Installing a package group pulls a set of dependent packages, saving time considerably.
|
||||
`yum` 是 Yellowdog Updater, Modified 的缩写，它是一个用于基于 RPM 系统（例如 RHEL 和 CentOS）的，开源的命令行软件包管理工具。它是从分发库或其它第三方库中获取、安装、删除、查询和管理 RPM 包的主要工具。

DNF stands for Dandified yum. We can tell DNF, the next generation of yum package manager (Fork of Yum) using hawkey/libsolv library for backend. Aleš Kozumplík started working on DNF since Fedora 18 and its implemented/launched in Fedora 22 finally.
|
||||
DNF 的含义是 Dandified yum。、DNF 软件包管理器是 YUM 软件包管理器的一个分支，它使用 hawkey/libsolv 库作为后端。从 Fedora 18 开始，Aleš Kozumplík 开始着手 DNF 的开发，直到在Fedora 22 开始加入到系统中。
|
||||
|
||||
Dnf command is used to install, update, search & remove packages on Fedora 22 and later system. It automatically resolve dependencies and make it smooth package installation without any trouble.
|
||||
`dnf` 命令可以在 Fedora 22 及更高版本上安装、更新、搜索和删除软件包， 它可以自动解决软件包的依赖关系并其顺利安装，不会产生问题。
|
||||
|
||||
Yum replaced by DNF due to several long-term problems in Yum which was not solved. Asked why ? he did not patches the Yum issues. Aleš Kozumplík explains that patching was technically hard and YUM team wont accept the changes immediately and other major critical, YUM is 56K lines but DNF is 29K lies. So, there is no option for further development, except to fork.
|
||||
由于一些长期未被解决的问题的存在，YUM 被 DNF 逐渐取代了。而 Aleš Kozumplík 的 DNF 却并未对 yum 的这些问题作出修补，他认为这是技术上的难题，YUM 团队也从不接受这些更改。而且 YUM 的代码量有 5.6 万行，而 DNF 只有 2.9 万行。因此已经不需要沿着 YUM 的方向继续开发了，重新开一个分支才是更好的选择。

一款免费且安全的在线PDF转换软件
|
||||
======
|
||||
|
||||
|
||||
|
||||
我们总在寻找一个更好用且更高效的解决方案，来我们的生活理加方便。 比方说，在处理PDF文档时，你会迫切地想拥有一款工具，它能够在任何情形下都显得快速可靠。在这，我们想向你推荐**EasyPDF**——一款可以胜任所有场合的在线PDF软件。通过大量的测试，我们可以保证：这款工具能够让你的PDF文档管理更加容易。
|
||||
|
||||
不过，关于EasyPDF有一些十分重要的事情，你必须知道。
|
||||
|
||||
* EasyPDF是免费的、匿名的在线PDF转换软件。
|
||||
* 能够将PDF文档转换成Word、Excel、PowerPoint、AutoCAD、JPG, GIF和Text等格式格式的文档。
|
||||
* 能够从ord、Excel、PowerPoint等其他格式的文件创建PDF文件。
|
||||
* 能够进行PDF文档的合并、分割和压缩。
|
||||
* 能够识别扫描的PDF和图片中的内容。
|
||||
* 可以从你的设备或者云存储(Google Drive 和 DropBox)中上传文档。
|
||||
* 可以在Windows、Linux、Mac和智能手机上通过浏览器来操作。
|
||||
* 支持多种语言。
|
||||
|
||||
### EasyPDF的用户界面
|
||||
|
||||
|
||||
|
||||
EasyPDF最吸引你眼球的就是平滑的用户界面，营造一种整洁的环境，这会让使用者感觉更加舒服。由于网站完全没有一点广告，EasyPDF的整体使用体验相比以前会好很多。
|
||||
|
||||
每种不同类型的转换都有它们专门的菜单，只需要简单地向其中添加文件，你并不需要知道太多知识来进行操作。
|
||||
|
||||
许多类似网站没有做好相关的优化，使得在手机上的使用体验并不太友好。然而，EasyPDF突破了这一个瓶颈。在智能手机上，EasyPDF几乎可以秒开，并且可以顺畅的操作。你也通过Chrome app的**three dots menu**把EasyPDF添加到手机的主屏幕上。
|
||||
|
||||
|
||||
|
||||
### 特性
|
||||
|
||||
除了好看的界面，EasyPDF还非常易于使用。为了使用它，你 **不需要注册一个账号** 或者**留下一个邮箱**，它是完全匿名的。另外，EasyPDF也不会对要转换的文件进行数量或者大小的限制，完全不需要安装！酷极了，不是吗？
|
||||
|
||||
首先，你需要选择一种想要进行的格式转换，比如，将PDF转换成Word。然后，选择你想要转换的PDF文件。你可以通过两种方式来上传文件：直接拖拉或者从设备上的文件夹进行选择。还可以选择从[**Google Drive**][1] 或 [**Dropbox**][2]来上传文件。
|
||||
|
||||
选择要进行格式转换的文件后，点击Convert按钮开始转换过程。转换过程会在一分钟内完成，你并不需要等待太长时间。如果你还有对其他文件进行格式转换，在接着转换前，不要忘了将前面已经转换完成的文件下载保存。不然的话，你将会丢失前面的文件。
|
||||
|
||||
|
||||
|
||||
要进行其他类型的格式转换，直接返回到主页。
|
||||
|
||||
目前支持的几种格式转换类型如下：
