Creating a NFS share is quite easy, and it’s a fast way to share files between Linux hosts, and apparently even with recent Windows machines (untested). Samba (SMB) is the native way to do it in Windows, but comes with some more overhead which reduces its file transfer speeds (untested). NFS Required packages The required packages are the following: # Arch Linux sudo pacman -S nfs-utils # Debian and derivatives (Ubuntu, etc.) sudo apt install nfs-kernel-server Share creation After choosing the folder you want to share, you’ll need to define the shared folders inside the /etc/exports file (created after the package installation). ...

In the last days I set up a node of a decentralized VPN using the Mysterium network. This was mainly to get profits from the Internet bandwidth I don’t use and to help provide freedom of speech for those who need it. What is Mysterium? Mysterium is ‘a global, distributed network powered by everyday people. Network participants are incentivised to share their resources in a supply and demand marketplace, helping others gain access to the open internet’. It is basically a blockchain-operated VPN service, where customers pay with the MYST token to connect to the nodes ran by volunteers who receive a compensation for it, also in MYST. The main benefits are that the exit IP addresses of your connection are the ones of regular people and not well-known business IPs, which makes it harder for content providers to deny your access to content they usually block for VPN users. Node runners, in return, receive a cryptocurrency that can be exchanged for many others. It isn’t very valuable for now (1MYST=0.17$ at the time of writing), but it’s for sure a compensation for a service that some would provide for free. ...

Securing your linux server is an essential aspect to keep it running and to avoid any infiltrations in your network that could lead to data breaches, which nobody wants. ...

What’s this Endlessh is a piece of software that sets up a ssh honeypot for all the random people that may try to attack you by trying common username and password combinations to see if they can get access. In return, this program slows their access down hugely, and in a way someone with a script to do the attack won’t notice (most people doing these kind of attacks will be using scripts). ...
