I've installed Java (1.8) and icedtea, but when I use (sudo) javaws myapp.jnlp it acts like it's going to start, prompting me with a "Are you sure you want to run this application" dialog, but when I click "Yes," it closes, stating this:
ERROR: javax.jnlp.BasicService not available
This application must be started by Java Web Start
Is this a problem with icedtea or a problem with the application itself? And, do you know how I can fix it?
I'm on a Raspberry Pi, but I don't know which one. If I had to guess, I'd say it's a 3, and it's using Raspbian.
Install the Icedtea Plugin by typing:
sudo apt-get install icedtea-8-plugin
If the File is still not opened look for it in the file manager.
Right click, open with...
Second Tab "userdefined..."
/usr/lib/jvm/java-1.8.0-openjdk-armhf/bin/javaws %f

Recently I decided to install Terraria server on Ubuntu Linux, but didn't find any completed instructions, so I decided to make my own, to help pure Terraria fans like me. This arcticle is relevant on 15.02.2019.
So first of all, you need a dedicated server. I used vps server from Heztner guys, but you can use any kind of tech you want (like raspberry pi or old pc with Ubuntu Server installed. Just make sure its minimal configuration fits Terraria Server).
After you first powered up your device and created password, we'll install SSH to make our setting up process a little bit comfy. You will be able to access server with any other device, if you have ssh installed in cmd or terminal.
Windows 10
Has SSH preinstalled in cmd. So all you need to do is
Type ssh-keygen (it will ask you to point the folder to extract keys, you can do it or just press enter)
Type ssh-copy-id "username"#"yourdeviceip" (Example: root#116.23.106.75)(In username type root)
Enter root password and you're in ')
Ubuntu 18.04
You may need to enable SSH in terminal. Use this instruction. Process is the same as in cmd on Windows 10.
Also
You can use SSH clients like Termius, you just need to create new Host with enabled SSH and put your server ip. Then choose user and enter password, and you're in.
Finally we're done with SSH and begining to setup our working environment. To fully operate with our system, we need to install several programs, as
mono-complete (to emulate windows shell environment, so TShock can work properly)
screen (to detach our terraria server screen)
unzip
And finally our Terraria server
Installation
First we create different user, so we store Terraria files separately of root.
adduser terraria
Then add it to sudo group, so you can launch several admin commands
adduser terraria sudo
Then install programs
sudo apt-get install mono-complete screen unzip
Enter as terraria user
su terraria
Go to your home folder
cd
Download latest TShock file, for me it's 4.3.25. If there is newer version, just go to their github page and copy zip file download link and paste it instead of mine.
sudo wget https://github.com/Pryaxis/TShock/releases/download/v4.3.25/tshock_4.3.25.zip
Unzip it
unzip tshock_4.3.25.zip
Delete zip-file
rm tshock_4.3.25.zip
Execute server one time to create the map
mono-sgen TerrariaServer.exe (type it every time you want to launch the server)
And now, when the map created and launched, you simply press ctrl+a to start screen, and then press d. Now your screen is detached and you can use your console regardless of server. Also this wont let your Terraria process shut down because of inactivity.
Bonus level
And this part will be for people who want to transfer their local map to server. I did it because first time I played Terraria with friends through Steam, and then I created server so map can run 24/7.
All you need to do is create ssh connection from device you store your local map. If you did it previously, then go to your Steam folder, find Terraria worlds, right click, properties and copy the path. Then go to cmd and type
scp "yourworldpath" terraria#*yourserverip*:~
It will copy your local world to home section, then go back to your ssh with terraria user and type
cd
mv "yourworldname" .local/share/Terraria/Worlds/
That thing will move your world file to hidden .local folder, where all world files store. Aaaand that's all. Just go to number 8 and do it again. Hope this guide will help you:) If you find any mistakes or face with problems, just comment this section, so I can fix it.
I have installed NetBSD 6.1.5 with full installation setting. However, when I run startx it says no screens could be found. So i tried "X -configure" and then "X -config ~/xconfig.conf.new" and I was brought to a very generic screen with a black x crosshair, but I was unable to exit this using the suggested ctrl+alt+backspace, so I had to force power off and check if my keyboard was recognized in the conf file generated, which it was. I have installed xdm, xterm, Xorg, and other X programs.
I am not familiar with setting up desktop environments from scratch. I am a newb who is used to Ubuntu esque installers doing that stuff for me.
Would someone be able to walk me though the installation or point me to a link which explains a step by step process?
What happens if you rename your xorg.conf.new to /etc/X11/xorg.conf? Does startx or xdm work then?
Are you running this inside a VirtualBox or other emulator?
I have NetBSD on a Thinkpad T420 which I occasionally boot into Windows, and I've setup VirtualBox to be able to run the same NetBSD install when I'm in Windows. The key difference in the xorg.conf file is in the Device section:
Section "Device"
Driver "vesa"
EndSection
Also I've found the free version of http://mobaxterm.mobatek.net/ very handy - I use it to ssh into the virtual NetBSD box and then run X apps and have them display on the Windows desktop.
Final note - you might want to look out for the NetBSD-7 RC1 which should be out 'Real Soon Now', as there are some very handy improvements, including better support for most modern display hardware :)
I found that running startx from any directory with a .xinitrc file gives strange behavior in amd64 6.1.5 and 6.1.4. Delete (or rename) any .xinitrc files and try
xinit /path/to/windowmanager
Please read Chapter 9 of NetBSD Guide:
http://www.netbsd.org/docs/guide/en/chap-x.html
Section 9.9 discusses installing various Desktop Managers/Environments.
It turns out that I could run "X -config xorg.conf.new" as root on host and then ssh using putty to manually launch windows.
http://zzsethzz.blogspot.de/2013/02/install-chromium-upgrade-it-to-chrome.html
According this tutorial, I should remove all HDDs I do not want to install chromium OS to during install. I wanted to try this guide on my imac using an external SSD for chromeos. Obviously, removing the HDD isn't an option. Will the chromiumOS installer format my mac drive too, if I don't remove it?
AS the writer of that tutorial I can hopefully help you. When you install Chromium OS to begin with you can specify where to install to if you know your unix commands well enough. and then from there you can update to Chrome OS once you have your external working for you.
To find out what your hard drive is when connected, open a terminal (you may need to use a developer terminal) and use the command "fdisk -l" This will list your hard drives. for example /dev/sda1 etc...
Your install command would be "Install /Dev/sda1" but replace the dev part with whatever your hard drive was listed as. If you need further help email me at admin#xiaorishu.co.uk
Is there an easy way to get xsp4 running as a background process on a linux server?
When I run xsp4 I get this:
xsp4
Listening on address: 0.0.0.0
Root directory: /test
Listening on port: 80 (non-secure)
Hit Return to stop the server.
So if I quit the terminal I am running it from it stops the server.
Do I have to write a daemon to do this? Or is there already something in place that I am missing?
Thanks
You have a couple of options. If your problem is terminal closing, then screen can be simple solution (just run screen xsp4, then Ctrl+A,D and you can close terminal). If the method you have used suits you, then use it -- however xsp will die after terminal closing. xsp should be generally used for debugging, production solutions are FastCGI or apache module, so these are daemons "by definition".
I had to use Mono for a demo that I had to show, and faced the same problem. My workaround was:
xsp4 --nonstop &
Note: It will show the initial information and if you hit enter, it will continue running. You can also exit the terminal if you want and it will continue as well.
you can do install the xsp4 in the terminal
sudo apt-get install mono-xsp4
then
go to your project Folder where the Asp project saved and type in the terminal
xsp4
Developing a program on OSX using Java and IntelliJ. Deals with network sockets and ICMP. Hence, the program needs to be run as root or sudo'd on OSX. Program runs fine from a terminal window outside IntelliJ under sudo. However, I would like to debug and run it from IntelliJ (V9). In IntelliJ it errors (I need root privs to enumerate network devices). I know how to pass program and VM parameters in IntelliJ but now how to hit Run and/Debug and have it run under sudo? What is needed is basically sudo java ...... MyProgram instead of java ..... MyProgram Any ideas or workarounds.
I came out with an answer and wanted to share it just in case anyone else runs into this. To solve the problem, I took my cue from what I do with QT & QT Creator when doing network programming.
On OSX, I opened up a terminal window and cd'd down to/Applications/IntelliJ IDEA 9.0.3.app/Contents/MacOS. There you will find a file called idea which launches the IDE. I ran that as sudo (sudo ./idea). That took care of permissions on anything Intellij launched and I could debug and step through my code as needed.
sudo /Applications/IntelliJ IDEA 9.0.3.app/Contents/MacOS/idea
Since this is a dev machine and I am in control of it security is not an issue in this case.
Hope it helps someone else out.
Inside a terminal:
sudo -s
give access to the root user.
from there you could run the Idea IDE using the script:
/Applications/IntelliJ\ IDEA*/bin/idea.sh
and in this way I'm able to work on network where permission errors where printed before.
Debugging of sudo programs is disallowed by the operating system unless the debugger is running as root, for security reasons.
So, even if you can figure out how to get IntelliJ to use sudo it won't do you any good.
I know this is not what OP directly asked -
In case someone needs to do this on Linux (Ubuntu), e.g. in order to update Idea, just run from command line:
sudo /usr/local/bin/idea
Only make sure once the Update and Restart is finished to actually close Idea and start it normally
I agree with #Darron, it is not recommended to execute IntelliJ with sudo.
You can execute with IntelliJ terminal instead.
I maintain my project in IntelliJ. When I need to execute a unit test that requires sudo access, I just open IntelliJ terminal and type:
sudo gradle test
Good luck!
