If you already got Quantum (and why wouldn’t you, its awesome!) I’d recommend getting previous version of Firefox, such as this Sep 2017 release and install to different folder than your Quantum. Make sure to disable Firefox updates.
Get Opera portable browser, and install to folder on the desktop, you can delete it when finished or keep till next time. Video below page break will tell you how to add VPN. You’ll need to enable Chrome extensions with this addon.
Install Chrome if you do not have it, if you do, go ahead and install Windscribe extension. Video below has process outlined for major browsers.
How do I learn to be a Linux sysadmin? on Reddit
I recently stumbled upon great resource on on /r/linuxadmin/ and I believe it is worth spreading. Do not expect detailed tutorials chock full of screenshots – /u/IConrad gives you list of tasks which build upon each other. It will be long journey, as it’s estimated whole task list would take 3-6 of full time study.
If you want to embark on this journey here’s the short excerpt from the quide:
This is what I tell people to do, who ask me “how do I learn to be a Linux sysadmin?”.
1) Set up a KVM hypervisor.
2) Inside of that KVM hypervisor, install a Spacewalk server. Use CentOS 6 as the distro for all work below. (For bonus points, set up errata importation on the CentOS channels, so you can properly see security update advisory information.)
3) Create a VM to provide named and dhcpd service to your entire environment. Set up the dhcp daemon to use the Spacewalk server as the pxeboot machine (thus allowing you to use Cobbler to do unattended OS installs). Make sure that every forward zone you create has a reverse zone associated with it. Use something like “internal.virtnet” (but not “.local”) as your internal DNS zone.
4) Use that Spacewalk server to automatically (without touching it) install a new pair of OS instances, with which you will then create a Master/Master pair of LDAP servers. Make sure they register with the Spacewalk server. Do not allow anonymous bind, do not use unencrypted LDAP.
It gives nice sense of progression, and to quote the author:
“Each “step” had a reason for being suggested; and the reason for the entire collection of steps was to represent a first-time exposure to conceptual categories of things that the daily work of the Linux/UNIX sysadmin might entail. Amongst other things you pick up knowledge of:
- Managing virtualized OS instances
- Server provisioning / automation
- Server configuration management
- Patch management in clustered environments
- Load balancers
- Network architecture
- User management
- HA Architecture
- Web-app stack architecture
- Researching and implementing solutions on the basis of partial specifications.
I have freshly installed CentOS7 box sitting behind the best router in the world, more commonly known as VirginMedia Hub 3. I’d like to have some services available facing the world, however Virgin’s box doesn’t not have built-in dynamic DNS settings.
After reviewing multiple comparisons of free Dynamic DNS services, I decided to use noip.com as it comes highly recommended and I already had an account there. There are some caveats: one has to log on monthly to the website (still, beats paying monthly subscription fee) and noip.com uses it’s own non-standard client software which has to be installed from source. I don’t think there’s any point asking them for RHEL/CentOS specific package. Continue Reading
