Block remote root login via ssh on Ubuntu/etc to keep your server safe A moment ago I was checking the system logs on my Ubuntu server and found that in auth.log reports that someone was repeatedly trying to SSH login as root. The "root" entry in /etc/passwd is setup so that no password will ever be matched, so perhaps this potential cracker would never get into my server anyway. But the requests are using bandwidth - and what if they were able to figure out a password that would work? Why not just block remote SSH login access to logging in as root in the first place? It's a bad idea to login directly as root - instead the recommended best practice is to login as a regular user then use sudo to perform things requiring super user access.
Installing Skype, photo/video editing, word processors, and more on a Chromebook Chromebooks offer respite from antivirus software hassles, system maintenance hassles, and more. The idea is that with the Chrome web browser as the only user interface, people can compute in safety. But what about the whole slew of existing software that runs outside web browsers - Skype being just one example. What about video or audio editing? What about traditional word processors or spreadsheet applications? None of those run inside a web browser. Yet. For a long period of time the only way to install Skype involved installing Crouton, the add-on supporting Linux software as described below. Since this was originally posted in Feb 2014, Microsoft released an official Skype for Chromebooks. However, Crouton is still useful because of the need for other software such as Gimp, for image manipulation.
Successfully mounting Drobo shares from a Chromebook with Crouton/Ubuntu 14.04 installed The last couple weeks I've switched my working environment from a MacBook Pro to a Chromebook that has Ubuntu installed under Crouton. A lot of my work is developing Node.js software, and writing website content, and my habits are to live at the command line typing commands. But it also means accessing the large amount of content I have stashed on the MacBook Pro, and a Drobo 5N. MacOSX can easily mount shares on the Drobo, letting me access those files as if they were on the local machine. By default Chromebooks cannot do this, meaning the Chrome browser side of my Chromebook cannot (at this time) access anything stored on the Drobo. Because Ubuntu is installed (via Crouton), that side of the Chromebook theoretically can mount shares on the Drobo, but I ran into problems trying to directly mount the SMB share using Ubuntu 14.04 tools. Fortunately I've developed an alternate method that's nearly as good and quite easy to implement.
Why do we need Skype et al on Chromebook - should Google do everything for us? Yesterday we wrote how to install Skype and other desktop software on ChromeOS devices, using Crouton. Today we ponder 'Why?'. Google intends the ChromeOS environment to provide a huge portion of our needs, but we went to a lot of trouble to install Crouton. Are we nuts? No, there are valid ideas going on here.
