Proxmox / LXC – Running docker inside a container

In relation to Debian / Proxmox – Install Docker with Rancher and DockerUI webgui on a Debian / Proxmox Server

I thought that it actually may make more sense to run Rancher and my docker inside an LXC container rather than on the initial host itself.

I went back to utilize an old Machine with Proxmox for containers but also wanted to have a platform to play with Docker. So I though pimping the Promox server is the best solution.

The Steps are easy to get docker running but since Proxmox offers the best GUI for lxc I needed something similar for the docker containers.

Note: This DOES NOT add Docker into the Proxmox GUI itself. I’m adding a separate web page for docker running in a container by itself.

PCI-DSS 3.2 has one major new requirement which is 2-factor authentication. There are many ways to get that done in an Enterprise environment. But how about a standalone webserver for E-commerce or DMZ without central auth? When a ssh-key authentication is not enough, the quickest solution for a server could be to make ssh to ask for 2-factor token when logging in. 2-factor authentication is based on one part where you need to know the password plus something you need to have additionally. You can create a separate key on an external device like a tablet or mobile phone. There are also devices like RSA token but that’s not part of this. Here I plan to use Android tools like FreeOTP, Authy or Google Authenticator for the passkey. They usually produce every 30 seconds a new key based on OATH. Let’s secure the ssh access now. Setup: Firstly we need to […]

As part of upgrading / rebuilding with Ubuntu 16.04 LTS and the sheer amount of packages that come with the upgrade or port fresh install, I looked into how to speed that up a bit further. I mentioned already before apt-cacher-ng to run a local proxy and avoid downloading the same packages over and over for multiple systems. However on 2 systems I have a huge amount of sources.lists which makes even the apt-get update process very slow / time consuming. So I looked into how to speed that one up bit. in Fedora/CentOS/RedHat there is a tool called deltarpm which adds support for downloading the deltas to generate new or updated packages. The there is a similar tool in Ubuntu / Debian. Debdelta “debdelta is a program suite designed to compute changes between Debian packages. These changes (deltas) are similar to the output of the “diff” program in that they may be used to […]

Updated:        2016-10-08 Wine Version: 1.9.20-staging Using my SEO to get the message out. I admit, I play World of Tanks and I play it on Linux with Wine (PlayonLinux). It has its install script there, and it works flawless. Issue #1 WOT Launcher crashes when downloading an update A change in the launcher by Wargaming recently, now forces to use the torrent protocol to download and share updates. That’s not working well on Linux and while in the old client it has to be disabled in the client settings under options while installing its now more hidden. Taken from here http://forum.worldoftanks.eu/index.php?/topic/533831-serious-problem-with-new-launcher/page__pid__11606193#entry11606193 and full credit to Ch4t_0ff. The new solution is to go to the WOTlauncher.cfg file which is located under: ~userhome/.PlayOnLinux/wineprefix/WorldOfTanks/drive_c/Games/World_of_Tanks/ and change <launcher_transport>3</launcher_transport> to 2. 3 is torrent transport 2 is direct download. That will make the updates downloadable on the Wine client. Issue #2 WOT graphic issues and artifacts when starting […]

If you are a small business, offering services, you probably are working out of your Email inbox rather than copy and paste your stuff over cloud-based business tools such a Vtiger or sugarCRM or others. And I think there is nothing wrong with it. Depending the size and if you need collaborators or not, this may be a good solution for you. And there is nothing wrong with this. If you are using Gmail (or Googlemail in some parts of Europe) you may avail of the power of being able to combine several mailboxes together by fetching emails from there and to be able to send as those emails addresses. You feel that it’s easier to not leave and or copy and paste stuff around to get organised. And you may be right. Let me show you a few things to get your inbox under control and to make your Gmail a lightweight CRM. […]

Inspired by the Xen Orchestra Team https://xen-orchestra.com/blog/migrate-from-xenserver-6-2-to-6-5/ I wanted to upgrade my hosts to the latest Alpha for testing, but I didn’t want to mess around with burning a DVD and boot off it. Now this solution is not necessary faster than booting off a local DVD depending on network speed and the NFS server, and also that the upgrade is running sequential host by host. However I could kick it off and leave it alone for some while and when I came back it was all done. NOTE: This is not a strict online Upgrade. If you have HA configured the upgrade will try to move the VMs around to the available hosts before upgrading and rebooting, if not several weird behavior will occur. What do you need: From http://xenserver.org/overview-xenserver-open-source-virtualization/prerelease.html The XenServer 6.6 Alpha3 ISO (or latest) XenCenter Windows Management Console (The latest version belonging to the Xenserver version to be […]

Upgraded an elderly Advent Laptop with a Conexant Smartaudio HD sound chip to Windows 10. It all went generally smooth and giving it some RAM (2GB) the Laptop runs well enough with Windows 10. However something weird was going on with the sound. Even though the driver is installed and seems to work there is no sound at all coming out. This was already happening with the TP Versions but also persists on the Final Release. Here is how I make it squawking. 1. Check we’re on the same page with our issues. If you have a marked driver as failed then you surely have some other issue. Right-click the Start button and go to device manager and you see in the device as running and all seems fine. In the taskbar click the speaker icon and check that you have the volume set up.    Here we go. Right-Click on […]

The News has broken, Lastpass has been the victim of an attack. https://blog.lastpass.com/2015/06/lastpass-security-notice.html/ While it’s not know if and how much impact that has at the moment, I’m personally not majorly concerned about my vault because I use some additional security settings which I layout here. In this case still rule No. 1 Change your master password immediately. Then login into your vault and into your settings to make those additional settings: -> Account Settings -> General -> Show Advanced Settings   ->   Scroll down to “Country Restriction” and activate to “Only allow login from selected countries” and select the country you are located in and in which you use Lastpass as well if you are traveling regularly. Example Also it’s strongly advised to use a 2-factor authentication which asks you always when you login from a new device for a second pin code that should be on a […]

Got this when trying to connect to a Windows 10 Technical Preview using Remmina after a Windows upgrade. Somewhere, somehow the key must have changed. I fixed that by deleting the freerdp known_hosts entry. vi ~/.freerdp/known_hosts Remove the host entry for the particular server. When trying to reconnect it will ask you to re-authorize the host. Done. No related posts.
