NextCloud Updates

     I updated NextCloud to version 13.01 and along with that update I also installed a bunch of new applications including a radio app that allows you to listen to a number of different station around the world.

     If you don’t have a NextCloud App on your I-phone or Android device, visit your play store and pick one up.  You can access anything you have stored here if you make it available, as well as many cool apps.

     You can also visit from any web browser at https://www.eskimo.com/nextcloud.

     The login and password are the same ones you use for e-mail, shell, and ftp access.

In general the debian derived systems have a much richer software base.

   Well no it won’t be down again tonight as I tried the fix on a less traffic’d machine first and it did not work.  Code Intel claims fixes the problem doesn’t.  So it’s back to the drawing board for now.

     I was able to obtain microcode from Intel that is supposed to mitigate spectre variant 2.  I’ve found documentation as to where to put it so that the kernel picks it up at boot time.  However, for reasons I do not understand even though I have copy host CPU information checked and the host is a Broadwell i7-6850k, KVM/Qemu keeps changing that to Skylake as soon as the machine boots so the microcode does not apply correctly.  I am thinking perhaps this is because this was originally installed on Skylake so to work around this I may move this virtual domain back to a Skylake based machine. 

     CentOS 6 and Scientific Linux 6 will both be down for about an hour tonight to migrate them back to the hardware they were initially installed on.

     I am going to take MxLinux down for about 90 minutes to image the machine, now that the x2go issues are resolved, so that if I have to restore it from backups, it is restored in to a working state.

     With the help of RIck Bressler, I found there was an issue with monkeysphere and certain directories in $PATH and x2go.  So ended up removing monkeysphere which then made x2go work again.

     Presently “x2go” is not working on mxlinux for regular users, it is only working for the root super-user account.  I am still troubleshooting and it will probably take a few days as I’ve run out of ideas and am consulting the authors.

     Those of you who remember the old terminal game nethack may wish to give glhack a try.  It’s nethack with a full color graphical display rather than the old terminal interface.

     To use it you’ll need to have x2go installed on your machine.  X2go can be obtained for free for Windows, MacOS, and Linux platforms from https://wiki.x2go.org/doku.php

     It gives you a graphical desktop access to our shell servers (except for the ancient ‘eskimo.com’ SunOS machine, that machine does not have enough memory to support a full graphical environment).  It provides a full graphical desktop with mouse and keyboard and sound, also remote printing and the ability to mount your directory here locally on your machine or some portion of your local file system here.  There is also the ability to use USB devices remotely but I have not mastered that one yet.

     Anyway, if you have not yet installed x2go on your machine, please consider doing so, it’s a secure way to connect with full graphics, sound, keyboard, and mouse, and even remote printing, to any of our Linux shell servers.

     Glhack and many other graphical games are available on mxlinux.eskimo.com, our newest addition to our shell servers.  It is located in /usr/games, so if /usr/games is not in your path then you will need to invoke it as /usr/games/glhack.

     MxLinux.Eskimo.Com is back up, with a bit more generous allotment of resources.
