Comment on Quick way to access remotely your GNU / Linux Desktop – Access Linux Desktop from Mac and Windows 7 by admin.

Just a small note. For corporate company world in companies like Hewlett Packard / IBM / Concentrix etc., instead of XMing for simlating Xserver on Windows to which GUi applications frm Linux / Unix / BSD can connect is used often proprietary software called Reflection X(also known as Reflection Desktop for X) – https://www.attachmate.com/products/reflection/desktop-for-x/
For example in HP the centralized internal corporate install software called PC COE is used to freely deploy Reflection X in case if you need it to install software that requires a Xserver (has X installation) such as Oracle client on linux but the remote server doesn’t have XServer installed.

If you're wondering for a good and quick to install VNC client for Windows RealVNC (because TightVNC being isntalled installs also unnecessery server). RealVNC rox ! 🙂

Of course there are easier non-free software to use to access remotely a Linux host like TeamViewer, but its always better to use free software to connect remotely than proprietary ones.

Install and configure rkhunter for improved security on a PCI DSS Linux / BSD servers with no access to Internet
       –rwo, –report-warnings-only
              This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
              be used to force other items of information to be displayed.

       –sk, –skip-keypress
              When  the  –check command option is used, after certain sections of tests, the user will be prompted to press the return key
              in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.
