Resilio Sync (formerly known as BitTorrent Sync) is a P2P file transfer tool based on the torrent protocol. Its main advantages compared to classic transfer tools are speed, simplicity and the very foundation it was built on: torrent-style transfers. In simple terms, the more “nodes” you have the faster the information can be uploaded or downloaded, at the same time.

This tool works best on Linux therefore this tutorial will cover the basics of installing on Ubuntu/Debian or CentOS/RHEL.

There comes a time when the control panel or your site in general exhibits a strange behavior claiming “No disk space left” or “Inode count full” while there is plenty of disk space available. This is down to inode usage . Inodes are filesystem structures which describe (among other attributes) a file or a directory. They can be of 1kb (or smaller) and up to 4.7GB (or more depending on the filesystem) which means that an email file or thumbnail can and will take up 1 inode. More info on inodes on the wiki – https://en.wikipedia.org/wiki/Inode . For an… read more +

You might have noticed the recent addition of a new feature in the left menu called “SSH Keys” and was looking for more info on it.

What is Public Key Authentication

The SSH protocol supports several authentication methods. One of the most important is public key authentication for interactive and automated connections.

Reason behind this is very simple: security. Public key authentication provides a very secure “password” using cryptography to an extent not covered by plain, user-made passwords. In addition, the user no longer has to remember the password and simple password authentication can be disabled for increased security.

There are 2 keys… read more +
