Ubuntu 18.04 LAMP Server – Quick Setup and FTP to Webserver

I recently setup an Ubuntu 18.04 webserver to test webpages locally. I used tasksel to quickly install the LAMP server role as follows:

sudo apt update
sudo apt install tasksel
sudo tasksel install lamp-server

With the webserver up and running I needed to be able to FTP into the var/www/html directories to upload my HTML and CSS.

As Ubuntu server comes with SSH installed be default I decided to use that for FTP instead of installing something like vsftd (Very Secure FTP Daemon). FTP over SSH turned out to be a much simpler and quicker setup.

Warning: These steps do not restrict access to folders outside of the /var/www/html directories. As such this setup is not recommended for any kind of production server.

First create a new directory under /var/www/html:

cd /var/www/html
sudo mk dir newdirectory

Create a new user and give the user a password:

sudo adduser ftpuser
sudo passwd ftpuser

Finally give the new user the permissions that they need. Change the directory ownership and group:

sudo chown www-data:www-data /var/www/html/newdirectory

Give the group write permissions to the directory:

sudo chmod -R 775 /var/www/html/newdirectory

Add the new user to the www-data group:

sudo usermod -a -G www-data ftpuser

With this done I configured FileZilla to establish a secure FTP connection to my webserver.

Filezilla: Secure FTP using SSH File Transfer Protocol.

Ubuntu Server 14.04 (Trusty Tahr) – Quick Headless Transmission Setup

ubuntu-server-logo

This is a quick post with a brief explanation of how to set up transmission on Ubuntu Server (currently 14.04 (Trusty Tahr)).

First make sure your repositories are up-to-date:

sudo apt-get update

Install transmission:

sudo apt-get install transmission-cli transmission-common transmission-daemon

Check to make sure that the transmission-daemon is not running – if it is it will overwrite any configuration changes that we make later:

sudo service transmission-daemon stop

Locate the transmission-daemon settings file:

sudo find / -iname settings.json

Two locations are found for this file:

/etc/transmission-daemon/settings.json
 /var/lib/transmission-daemon/info/settings.json

We will edit /etc/transmission-daemon/settings.json:

sudo nano /etc/transmission-daemon/settings.json

The changes that I made to settings.json are in red. You will need to provide your own settings to configure your setup:

"download-dir": "your-download-location",
"incomplete-dir": "your-download-location",
"rpc-password": "password",
"rpc-username": "username",
"rpc-whitelist": "127.0.0.1,192.168.0.*",
  • download-dir and incomplete-dir are directories where complete and incomplete torrents are stored. They do not have to be different directories.
  • rpc-password and rpc-username are the username and password for web access administration.
  • rpc-whitelist defines access to transmission. Localhost (127.0.0.1) is defined by default. I added ,192.168.0.* to allow any machine on my LAN access.

Start the transmission-daemon:

sudo service transmission-daemon start

Verify that everything is working by opening a broswer and pointing it to http://server-ip:9091.

Ubuntu Server 14.4 (Trusty Tahr) – add-apt-repository: command not found

ubuntu-server-logo

The last time I encountered the add-apt-repository: command not found error I was using Ubuntu Server 12.4 Lucid. The solution then was to install python-software-properties as follows:

sudo apt-get install python-software-properties

 

This did not resolve the issue on my minimal virtual machine installation on Trusty so I installed apt-file – which is an apt package searching utility:

sudo apt-get install apt-file

 

Update apt-file:

apt-file update

 

Finally use apt-file to search for the add-apt-repository package:

apt-file search add-apt-repository

 

As you can see add-apt-repository is in software-properties-common:

software-properties-common: /usr/bin/add-apt-repository
software-properties-common: /usr/share/man/man1/add-apt-repository.1.gz

 

After installing software-properties-common I was able to use add-apt-repository without any further issue:

sudo apt-get install software-properties-common

Ubuntu 14.04 (Trusty Tahr) x86 – Minor Installation Issues

ubuntu-logo

I experienced two issues trying to install Ubuntu 14.04 x86 on my old laptop today:

  • ubi-partman crashed (I clicked Continue)
  • Installation hung Getting the time from a network time server

I encountered these issues booting from DVD and then clicking on the Install Ubuntu button in the installer.

Fortunately I did not encounter either of these issues when I rebooted and then clicked Try Ubuntu in the installer and then installed Ubuntu from the Live DVD session.

 

 

Ubuntu 12.04 (Precise) – Could not apply the stored configuration for monitors

ubuntu-logo

Booting in to a clean installation of Ubuntu 12.04 (Precise) with VMWare Tools installed I get a Could not apply the stored configuration for monitors error:

Could not apply the stored configuration for monitors.
Could not apply the stored configuration for monitors.

The solution is to remove monitors.xml from /home/<username>/.config.

To do this I opened a Terminal and changed the directory to .config:

cd .config

I backed-up and then deleted monitors.xml:

cp monitors.xml monitors.bak
rm monitors.xml

I rebooted for good measure – now VMWare Tools adjusts my resolution without errors.

Ubuntu – Teamviewer 8 – lsb_release crashed with IOError in getstatusoutput(): [Errno 10] No child processes

ubuntu-logo

I installed Teamviewer 8 on Ubuntu 12.04 (Precise) today and started getting frequent random internal error messages.

ubuntu-internal-error
Sorry, Ubuntu 12.04 has experienced an internal error.

I did not capture all of the details but this portion led me to a solution when I searched for it:

lsb_release crashed with IOError in getstatusoutput(): [Errno 10] No child processes

To fix the error first open the Terminal.

Next change directory to /opt/teamviewer8/tv_bin/script:

cd /opt/teamviewer8/tv_bin/script

Make a backup copy of tvw_main:

sudo cp tvw_main tvw_main.bak

Open tvw_main in the nano text editor:

sudo nano tvw_main

Edit the file as per the screenshot below:

teamviewer-tvw_main

  • comment out lsb_release -a
  • comment out lsb_release -ds > “$WINEPREFIX/drive_c/distrelease”

After make_path “$WINEPREFIX/drive_c” make a new line and paste the following:

cat /etc/lsb-release | grep DESCRIPTION | cut -f2 -d= | sed 's/\"//g' >     "$WINEPREFIX/drive_c/distrelease"

Save tvw_main and exit nano – Ctrl + O, Enter, Ctrl +X.

Notepad ++ Unix Shell Scripts and the ‘No such file or directory’ error on Ubuntu Server

ubuntu-server-logo

I first encountered this issue a long time ago and forgot to document it – so now I had to resolve it again.

I’m running Notepad ++ on Windows and using WinSCP to transfer bash scripts to Ubuntu Server. My script is saved as an Unix script file (*.sh, *.bsh) in Notepad++ and WinSCP is set to transfer files in binary mode.

When I run the script on Ubuntu Server I get the following error:

: No such file or directory

I could see the problem in Notepad++ and in nano on Ubuntu Server when I wanted to save the file – the file was formatted for Dos\Windows.

dos-windows
Notepad ++ document format set to Dos\Windows

dos-format
Nano saving .sh as Dos Format

The fix is to change the formatting to UNIX. In Notepad ++ click Edit, EOL Conversion and UNIX and save the file.

Easy when you remember how!
