How To Run Your Own Git Server With GitlabHQ On Debian 7 (Wheezy)
Author: Srijan Kishore •
Tags: debian, linux •
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.

Comments: 3 Data Recovery Techniques on Linux When one of my friends called telling me that he had accidentally deleted some important files from his drive, his exasperation was understandable. 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.

Tags: linux, security •
Comments: 4 How to setup your OTP appliance with privacyIDEA In this howto we will setup a system that can act as your own personal OTP appliance, managing all authentication devices in your network. You then may configure your services to authenticate against this machine. It is a good idea to use some virtualization mechanism. If you have some old hardware around, this is even as good.
