ubuntu配置vnc相关功能,x11vnc,vino,krfb,tightvncserverIntroductionA VNC server is a program that shares a desktop with other computers over the Internet. You will need a VNC server if you want other people to see your desktop. Every VNC server has different strengths and weaknesses and is appropriate for different uses. This page will discuss each of the VNC servers available in Ubuntu, and ways to configure them for most common uses of VNC.Common security optionsThe most important thing when setting up a VNC server is to only let the right people access your desktop. The safest way to do that is usually to have someone sitting at the desktop deciding who gets to use it, but that's not always practical - for example, if you want to log in to your own computer from somewhere else.If you want to confirm each connection manually, you should look for these options:Request access each time - pop a window up asking whether to allow each connection as it comes in.view-only access - ...

 群晖Docker安装nextcloud私有云，以及onlyoffice、流程图和思维导图插件nextcloud是近年来NAS用户常用的开源私有云平台之一。该平台与其他开源私有云服务相比，具有相对友好美观的交互界面，丰富的可拓展功能，以及几乎全平台的客户端支持。自己之所以调研并尝试使用nextcloud，也正是因为这个平台丰富且使用的拓展模块和应用，例如在线的office编辑，绘制流程图，项目协作，以及思维导图等等。安装在群晖的NAS上面，是对群晖Drive，office等协作办公模块在功能上的补充。这里我把自己在群晖NAS218+上面安装nextcloud和相关插件的方法分享给大家，以期抛砖引玉，共同发掘私有云平台上既实用又好玩的功能。一、nextcloud私有云的docker安装首先，在群晖docker应用的注册表里面，搜索并下载wonderfall/nextcloud的docker镜像，如下图所示：搜索并下载wonderfall/nextcloud的docker镜像需要留意的是，在搜索结果中第一个nextcloud官网镜像不知什么原因在群晖上一直无法成功下载（用pc上的docker客户端是可以的）。而第二个linuxserver/nextcloud镜像，默认开启了https访问，这对于服务器或docker部署的初学者而言，搞定证书的安装和部署会是一个相对繁琐的流程。我们选择的...

Question: How to turn on scsi extended debug messages? What are the field/flag definitions of scsi_logging_level?Additional scsi logging messages can be enabled by writing to /proc/sys/dev/scsi/logging_level either via use of the echo or preferably the sysctl command. The kernel parameter consists of ten packed fields, each 3 bits in length. Each field can have a value of 0 to 7. The higher the field’s value, the more verbose the logging of messages associated with that field type.NOTE: Turning on high levels of extended logging and/or multiple types of extended logging can slow down system performance, especially during boot and shutdown. Unless needed, avoid turning on scsi logging during boot up.Run Time1. Enable :# sysctl -q -w dev.scsi.logging_level=[N]or# echo [N] > /proc/sys/dev/scsi/logging_levelWhere N specifies which fields to enable and at what level of verbosity.2. Disable:# sysctl -q -w dev.scsi.logging_level=0or# echo 0 > /p...

What is Chronyd ServiceIn CentOS/RHEL 7 and 8, the operating system’s time is set on every boot based on the hardware clock, which is a small-battery driven clock located on the motherboard of your computer. Often, this clock is too inaccurate or has not been set right, therefore it’s better to get your system time from a reliable source over the Internet (that uses real atomic time). The chrony daemon, chronyd, sets and maintains system time through a process of synchronization with a remote server using the NTP protocol for communication.In this post, we will learn to enable debug mode for chronyd service, which comes in very handy while troubleshooting any chronyd related issues. The configuration file used by chronyd service is /etc/sysconfig/chronyd.1. Edit the configuration file /etc/sysconfig/chronyd as a root user:# vi /etc/sysconfig/chronyd2. Add or Modify below line.OPTIONS="-dd"3. Copy /lib/systemd/system/chronyd.service to /etc/sys...

Configure Squid as HTTP and HTTPS Transparent ProxyLinux, Squid Proxyby adminThese days, it is really important to have proxy server to analyze web traffic of the organization. Among proxy servers, the Squid is very famous, because of it’s flexibility and easy of configuration. Squid can be operated at non-transparent and transparent mode which is going to discuss here. Main benefit of transparent mode is, clients are not aware that their requests are processed through the proxy. Simply there is no configuration at client side. So let’s look at how to configure Squid as HTTP and HTTPS Transparent Proxy Before begin please adjust the ip and other configuration as per your requirement.
