In the 2 previous articles, I explained how to set up a serial console on Ubuntu and Debian.
This tutorial will now show how to connect to those serial console using another machine using a software called minicom.
This tutorial will go over the steps to go through in order to set up a serial console on Debian Linux.
Debian uses sysvinit to handle the booting process, amongst the different task, and as such, there is a few differences between most of the tutorial that you might find on the internet regarding how to set up a serial console.
A Serial Console becomes handy when running a headless server (i.e no keyboard and screen) or if you cannot connect a a server because of a network issue.
This tutorial will go over the steps to go through in order to set up a serial console on Ubuntu Linux.
Unlike most other distros, Ubuntu uses upstart instead of sysvinit and as such, there is a few differences between most of the tutorial that you might find on the internet regarding how to set up a serial console.
A Serial Console becomes handy when running a headless server (i.e no keyboard and screen) or if you cannot connect a a server because of a network issue.
This tutorial will show how you can export and import a set of GPG keys from one computer to another.
This way, you can sign/encrypt the same way one different computer.
SSH is great. There is so many thing you can do with it other than just a remote secure shell like X forwarding, port forwarding, authenticate using a private/public key, compress the transmitted stream....
If you have different account that you use on an every day basis, it becomes quickly cumbersome to type those lengthly command lines.
One could work around this by using aliases, the right way would be to use ~/.ssh/config
This tutorial will show some customization examples that should cover most ssh use cases.
Chainloading an operating system allows grub to boot an opearating system's boot loader. This is commonly used to boot Windows for instance.
I personnaly use it to be able to have my "production" system's grub on the MBR, and address other distros'grub install on their root partition. The advantage is that kernel updates are real easy to handle. Each testing distro modifying their own grub won't interfere with my main OS bootloader.
This tutorial will explain how to configure grub's menu.lst from the main OS to boot other OSes bootloader through an example.
cron-apt is a tool run by a cron job at regular interval that will check for package updates and optionally do some actions.
cron-apt will by default download the packages without installing them.
This tutorial will explain how to set up cron-apt in order to have it send an email to a specified address when updates are ready to be installed.
A standard Linux system has an incredible amount of files installed. Looking for a file location can be a painful task to do though a file browser.
Fortunately, there is a nifty command line available by default on any Linux distribution: find.
find can virtually find anything on your computer and comes with a lot of options. This tutorial will introduce a basic use of it and show how you can search your filesystem for file names matching a name pattern.
Filesystems are usually created on a partition. When all your hard drive is already partitioned, creating a new partition can become a pain and creating a new filesystem within another filesystem file can save you a lot of hassles.
This tutorial will show the few steps required to have a new filesystem layout set within another filesystem.
This tutorial will explain how to create a self-signed certificate that you will be able to use with apache in order to provide ssl support.
A self signed certificate won't provide as much security guarantees than a CA-signed certificate, but at least you will be able to use encrypted connection to your server.
