How to use ISPConfig and Seafile without manual file modifications

Seafile is an open-source cloud based file storage system similar to Dropbox & Box. The difference is that Seafile can be deployed on a client's own system. This provides a greater safety and security factor as the passwords are only interchanged between the client who setup the system, and his / her own users rather than a corporate cloud hosting company.

How to secure your ISPConfig 3 server against the poodle SSL attack

How to secure your ISPConfig 3 server against the poodle SSL attack

In the following guide I will describe the steps to secure your server against the recent poodle SSL attack. I will use a ISPConfig 3 perfect server on Debian 7 for my examples, but the same steps will work on any other Linux Distribution as well.

How To Run Your Own Git Server With GitlabHQ On Debian 7 (Wheezy)

How To Run Your Own Git Server With GitlabHQ On Debian 7 (Wheezy)

This document describes how to install and configure Git and GitHub. These are great tools to manage and administer a whole host of Git repositories and the associated permissions. So, these remain true blessings for users writing open source software, however, when writing a closed source software may not be comfortable in trusting the code to a third party server. To gain the much-needed flexibility and control on stuff like Github/BitBucket without hosting the git repositories on servers that lie external to the control of users, GitLab remains a Godsend!

Debian Wheezy: Split and resize Xen disk image

Background

One of my Xen virtual servers needed to have its 400G disk split and resized over the weekend, and I wanted to keep downtime to a minimal. The disk had 240G used, 235G of which was a /backup directory, and the remaining 5G dedicated to a regular Debian Linux installation. I wanted to split the disk into a two disks - a 20GB disk containing the Linux system, and a 300G disk to mount as /backup. Then I could apply my DRBD setup to replicate that 300G backup partition to a separate 2nd backup machine.
