Enable auto-logon with systemd (non-GUI) (Ubuntu 16.04+ and Debian 8+)
edited by on March 21st 2019, at 12:24
The quickest way to enable auto-logon on Ubuntu 16.04+ and Debian (which are using systemd for management of their services) is by creating an override for the getty service, specifically for tty1 (or another tty if you prefer).

First, determine which tty you wish to have the auto-logon on. These are the terminals linked to the Alt+Fn keys, so tty1 = Alt+F1, tty2 = Alt+F2. The default is always tty1.

Next, create an override by typing:

sudo systemctl edit getty@tty1.service

This will open up a text editor where you can adjust the parameters like so:

[Service]ExecStart=ExecStart=-/sbin/agetty --noissue --autologin myusername %I $TERMType=idle

Replace myusername with the account you wish  ...
 
Configure tftpd-hpa to allow upload of new files
edited by on August 21st 2018, at 14:16
When installing tftpd-hpa, as a security measure, the service does not allow uploading new files. It does allow overwriting existing files, provided that the permissions are set correctly (as expected). The idea behind this is to secure TFTP a bit by only allowing uploads if the file already exists (and is writable). But this can be very tedious in some cases, where a lot of files have to be uploaded, and it is not possible to guess the names to create them in advance.

It is possible to configure tftpd-hpa to allow the creation of new files by adding the -c or --create parameter when starting the daemon.

For Ubuntu and Debian, this means editing the file /etc/default/tftpd-hpa, and adding   ...
 
Shorewall not automatically starting on Debian 9 (and some versions on Ubuntu 16.04)
edited by on August 18th 2017, at 14:27
There's an issue with the Shorewall package in Debian 9 Stretch, causing Shorewall not to automatically start even when the required configuration files are in-place and/or modified. As stated here, the problem also exists on Ubuntu with some versions of the package (see article).

The problem lies with the package not enabling the startup script in systemd during installation. The solution is to manually enable this by running the following command (as sudo):

systemctl enable shorewall.service

This will enable Shorewall to automatically start during a reboot. Note that you will still have to set the correct parameters in /etc/default/shorewall (and possibly /etc/shorewall/shorewall.conf t  ...
 
Installing latest nginx on Debian
edited by on June 8th 2017, at 13:59
nginx provides packages for Debian in their own repository, allowing you to install the most recent version rather than the older versions provided through the main repositories.

Add these lines to /etc/apt/sources.list:

deb http://nginx.org/packages/mainline/debian/ jessie nginxdeb-src http://nginx.org/packages/mainline/debian/ jessie nginx

Change jessie to wheezy if you are still on Debian 7 "Wheezy".

Download and add nginx's public key:

wget http://nginx.org/packages/keys/nginx_signing.key && cat nginx_signing.key | apt-key add -

Update the package list and then install nginx:

apt-get updateapt-get install nginx

By default, the latest version of nginx will be ins  ...
 
Debian 7 Wheezy download link
edited by on April 26th 2017, at 16:50

Although Debian 7 "Wheezy" (release info) has been superseded by newer releases, it still benefits from Long Term Support (LTS) until end of May 2018. In case of disaster recovery, it may still be useful to download Debian 7 install images (ISO). They can be found here:

Installing Open Monitor Distribution (OMD) on Debian/Ubuntu
edited by on January 18th 2016, at 15:10
Installing the Open Monitor Distribution (OMD) is actually pretty straight forward on Debian. Consol Labs provides a OMD repository from which the latest version of OMD can be installed, providing both a stable and testing branch.

First and foremost, you need to have a Debian/Ubuntu system running, and it needs to be connected to the internet.

In order to add the repository, you need to import the GPG security key in order to trust the repository:

gpg --keyserver keys.gnupg.net --recv-keys F8C1CA08A57B9ED7gpg --armor --export F8C1CA08A57B9ED7 | apt-key add -

Next, add the repository to your sources.list. For Debian 8.0 "Jessie", this would be something like this:

echo 'deb htt  ...
 
Get rid of WRITE SAME kernel error messages on linux (3.x kernel)
edited by on June 17th 2015, at 10:34
Linux distros with a 3.x kernel running on virtualized hardware (e.g. pvscsi on VMware) may ever so often spit out the following error:

$ dmesg | grep "WRITE SAME"
kernel: sda2: WRITE SAME failed. Manually zeroing.

This is because the disk driver (in our case: the VMware paravirtual driver) does not support the WRITE SAME SCSI command, resulting in this message.

While this poses no problem for the system at all, you may want to get rid of these messages, which is done by disabling the use of the WRITE SAME command. This can be done through a bit of configuration. Most modern systems have systemd on board which can be used for this, but in case your system doesn't, there's also a  ...
 
Change the console fonts on Ubuntu/Debian
edited by on June 12th 2015, at 15:55

You can efficiently change the console fonts, character sets and keymaps through the following command:

sudo dpkg-reconfigure console-setup

The configuration is stored in the file /etc/default/console-setup, and can be edited by hand as well.

The changes are effective for all virtual consoles after reboot. To apply the change for the current console, run:

setupcon

To prevent changing the console font completely (i.e. native system/BIOS font will be used), set the font to "do not change".
The equivalent in the config file is: 

FONTFACE=""
FONTSIZE=""
 
Debian: turn off incremental (pdiff) package updates
edited by on October 20th 2010, at 11:57
Debian has introduced incremental updating of package lists. While in theory, this is a great feature, it is not always practical.

Incremental updates enable to download less data by fetching only the differences between the previous versions of the list. This results in significant savings concerning the amount of downloaded data.
The unfortunate downside is that a whole lot more fetches need to be done as each incremental update requires a server request. This becomes apparent when you don't often download package list updates, and there are suddenly a whole number of files waiting to be downloaded. The overhead of requesting each incremental slice separately causes the update to take mor  ...
 
Input trouble with PuTTY SSH on Debian
edited by on April 28th 2007, at 00:37
If you happen to have keyboard trouble when you SSH with PuTTY to a Debian system, you might want to read on.
With trouble, I mean one or more of the following symptoms:

Numeric keypad not working, even with numlock enabled/disabled

Home/End keys not working as they should

Function keys not working as they should

Other weirdness concerning keyboard...

We've figured out a possible solution to the problem. It has been tested (and used) extensively by my and a collegue, and have found it working perfectly on Debian Woody and Debian Sarge.
It may be possible that these settings also work on other distros having similar problems. If it does, please let us know so we can add it to the article  ...
 
PHP with MSSQL on Debian/Ubuntu
edited by on March 26th 2007, at 20:08
Apparently, there's no package for MS-SQL support in Debian or Ubuntu. Why this is, is not very known, in particular since there is MS-SQL support in PHP4 and PHP5.
I found the following steps somewhere on the internet.

The following was tested on a Ubuntu 6.10 Edgy, but will probably work on others as well.
Also, whenever I refer to php5, it could well be replaced with php4, which I've tested as well.

First of, make sure the necessary build tools are installed:
# apt-get install build-essential debhelper

It's possible more tools are needed, depending on which ones have already been installed, but basically, if you can compile other packages from source, you should be good to go.

Installing phpMyAdmin on Debian 10
by on January 1st 1970, at 01:00

Starting from Debian 10 ("Buster"), phpMyAdmin no longer exists as a package in the Debian repository. Instead, it needs to be installed manually. I found this article online which seems to explain the process very well:

Bring up a network interface without an IP address in Debian
by on January 1st 1970, at 01:00
It is possible to automatically bring up a network interface without any IP address configuration in Debian. This can be useful for e.g. traffic flow monitoring where the interface is subsequently placed in promiscuous mode by software such as tcpdump.

Like always, all network interface configuration is stored in the file /etc/network/interfaces. For the interface you want to bring up without an IP address, add these lines:

iface eth0 inet manualpre-up ifconfig $IFACE uppost-down ifconfig $IFACE down

If the interface is a VLAN interface, the up/down commands must be executed after/before the VLAN hooks, so it should then read:

iface eth0.2 inet manualpost-up ifconfig $IFACE uppre-down if  ...
 
Create bootable Debian USB on Mac
by on January 1st 1970, at 01:00
While there are a lot of ways and tools to write bootable ISOs to USB on a Mac, the most easiest is in fact by using the "linux" method, a perfectly valid option using internal command-line tools:

You'll need an USB device that's large enough. For netinst, 1 GB would be sufficient. Make sure that the contents are kept safe if needed, as the USB device will be wiped.

If you haven't done so already, you can download the proper ISO file for Debian from this page: https://www.debian.org/distrib/. Download only from a legitimate mirror.

Insert the USB device and open up Terminal. We need to verify the device identifier of the USB device as we will need this later. This will be in the  ...
