Use Free Let’Encrypt SSL certificate in Webmin

For the purpose of demonstrating this tutorial I will be using Ubuntu 18.04 LTS.

Step1. Check Webmin version

Webmin can now request SSL certificates from Let’s Encrypt from within the UI. However to use this you will have to be at least on v 1.78

Step 2. Install Let’s Encrypt Client

Ubuntu 18.04

sudo apt-get install letsencrypt

Step3 – Configure Webmin

Goto Webmin –> Webmin Configuration

Click on the gear icon on the top left corner called the “Module Config”

Fill in the Full path to Let’s Encrypt client command field with the absolute path of letsencrypt

/usr/bin/letsencrypt

Goto Webmin –> Webmin Configuration and client on the box “SSL Encryption”

Click on the “Let’s Encrypt” Tab.

Click on the “Request Certificate” button

Step 4 – Completed

Refresh the Webmin interface and the site would now appear properly secured via HTTPS.

HOWTO: Setup a Time Machine Server on Ubuntu Server 14.04, 16.04, 18.04 & Debian

In this post lets look at the steps to quickly reconfigure a Ubuntu / Debian server to function as a Time Machine server. TM backup tested with OSX Mountain Lion , Mavericks, Yosemite and El Capitan.

  • Install following packages

sudo apt-get install netatalk avahi-daemon

  • Create a new folder which will contain the TM backup.

mkdir -R /data/TimeMachineBackup

  • Create a new user and grant access to the folder created in previous step

sudo adduser tux-networks

sudo chown -R tux-networks:tux-networks /data/TimeMachinebacku

  • Backup the default configuration file installed by apt-get

sudo mv /etc/netatalk/AppleVolumes.default /etc/netatalk/AppleVolumes.default.back

  • Create a new configuration file and edit using vi or other text editors

sudo vi /etc/netatalk/AppleVolumes.default

the following lines exist by default on my machine (this is default setting for all shares)

:DEFAULT: options:upriv,usedots

  • Add the new folder that was created earlier

/data/TimeMachineBackup “Tux Networks’s TM Backup” options:tm volsizelimit:500000 allow:tux-networks
options:tm –> timemachine
volsizelimit –> 500GB of space available for Time Machine
allow –> user id having access to this folder

  • Restart netatalk

sudo service netatalk restart

  • Connect to ubuntu server using Finder on your Mac in the “Go” menu, click “Connect to server…”. In the server address field type afp://192.168.x.x/ then click “Connect”, you will be asked to input a login and password which is the user created in step 3.
  • After connected, type Time Machine in search to open Time Machine app and click “Select Disk…” and select the new Ubuntu Time Machine server under “Available Disks”.
  • Provide login credentials if asked again.


Buffalo Linkstation ACP Commander GUI

ACP Commander GUI is a Graphical User Interface using acp_commander developed by Georg from NAS-Central. ACP Commander GUI is based on the code of acp_commander with some modifications for better integration into the GUI.

Original link: http://www.gry.ch/Java/styled/

Thanks to Georg for his nice work!

ACP Commander GUI can be used to remotely control your arm9-based LS Pro/LS Live/Tera Pro v2/Tera Live devices. I only tested it with an LS Live, but the others should work to.

I am keeping a copy of the files for my future reference, as I noticed NAS-Central is down since Aug’18.

Features:

  • Automatically detects LinkStations™ available in your network, just select the desired one from the pulldown box.
  • Execute Linux commands directly on the LinkStation™ and get the output in the log window.
  • Set the door password of the LinkStation™.
  • Enable SSH (sshd). It will also add a startup entry so that SSH is also available after each reboot.
  • Tested on Firmware versions 1.560 and 1.570.

Simply enter the admin password in the “Admin password” field and you are done. That is the one you do also use to login to the Web Interface of the LinkStation™. After that, simply click on one of the buttons to execute the desired action.

For more LinkStation™ information visit Buffalo Technology.

Note: The data that can be returned from the LinkStation™ is limited by the protocol. That means if you manually execute a command (like “ls”) on the device it could be possible that you don’t get the full result back. Just keep that in mind.

Warning: This is experimental software that might damage your LinkStation™.

HOWTO: Harden your WordPress wp-admin using password protection

Though wp-admin is already secured through login/password authentication, this post will examine to add an additional layer of security.

For the purpose of second layer security htpasswds file will be used.

Create htpasswds file

Use htpasswd command in Linux or OSX to create a htpasswd file. The command to execute  is as below

$ htpasswd -c .htpasswd mydemouser 
New password: 
Re-type new password: 
Adding password for user mydemouser

A file .htpasswd is created in the local directory

$ cat .htpasswd
mydemouser:$apr1$60sgQzdr$C.APpTFtRyjJfpcwQsJB/.

Changes on server hosting WordPress site

1. Copy the .htpasswd file to a directory that’s outside the wp-admin directory

Suggested Directory: /home10/mydemouser/.htpasswds/public_html/wp-admin/passwd/

Change the directory as per your site deployment.

2. Create a .htaccess file in ~/public_html/wp-admin directory and include following

 

AuthName "Restricted Access"
AuthUserFile /home10/mydemouser/.htpasswds/public_html/wp-admin/passwd/.htpasswd
AuthGroupFile /dev/null
AuthType basic
require user mydemouser

3. Access wp-admin page and confirm an authentication popup window appear. If the page fails with too many redirects error then proceed with the next step.

Stop too many redirects error

4. Edit the .htaccess under ~/public_html and add the following line before WordPress rules start

ErrorDocument 401 default

That’s it – double layer authentication should now be active.

<Files admin-ajax.php>
