Comments: 20 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. A default ISPConfig hosting server runs the following services: Webserver (Nginx or apache), Mailserver (Postfix and Dovecot / Courier), FTP-Server (pure-ftpd) that offer SSL / TLS connections and are potential targets for a poodle attack.

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

Comments: 3 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!

Comments: 3 How to setup Single Sign On with OTP using simpleSAMLphp and privacyIDEA This howto will deal with Single Sign On to web pages. Maybe you know OpenID. Similar to Kerberos a "Ticket" is granted to the user to authenticate at other services using the ticket and not the credentials anymore. In this howto we will use SAML (Security Assertion Markup Language) which is more sophisticated than the simple OpenID. SAML can be used to setup trust relations between several entities. This is why it is used between companies and organizations, why online service are using it.

Debian Wheezy: Split and resize Xen disk image
Author: aziods •
Tags: debian, linux, virtualization •
Comments: 0 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.

It happens to everyone at some point of their computer-using lives. Unfortunately, in his case, those were some extremely important documents that, had he not recovered them, could have proven very costly.
