Understand why AWX suddenly requires sshpass - ssh

I have been using an AWX server for some time for a project. I use AWX on standard virtual machine templates user root password root on which I always succeed to connect. Suddenly this morning the AWX tries to connect on one of the template in SSH and this error comes out : "to use the 'ssh' connection type with passwords or pkcs11_provider, you must install the sshpass program"
I tried to install sshpass on one of the templates but nothing changes, impossible to connect
I would like to be able to connect to my templates again

I have been running the same issue, it seems that the latest version of awx-ee execution environment is buggy, as described in the bug
Quick solution: Modify or create a new execution environment using the tag 2.11.0 instead of latest.

lb4 command is not found in Windows 10

I have install loopback 4 framework in my system by this command npm i -g #loopback/cli. But after installation by terminal I, can't create loopback application because it showing lb4 command not found. I also search through web and do many changes in environment variables but got same problem. I have executed this command with different terminal and same problem is getting.
I have attachments which will help you to understand the problem
I am running this command on command prompt in windows 10 system
This can occur for several reasons; Typically, it's caused by a misconfigured PATH variable or a stale "cache" of the terminal. A quick solution is to use npx #loopback/cli instead.

How to install Terraria TShock Server on Ubuntu Server?

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.

Fedora how to automatically run the ssh daemon

I would like to know what are the ways to automatically start daemons (sshd) in Fedora system. I know I can write a startup script that will put on /etc/init.d/.
What are the other options?
Somewhere I read that now in the new version of this can be done using the commands in the terminal, but I do not remember what it was.
EDIT: My 2 question.
I install ssh from source. When keys are generated for a server? During the installation?
You can do this via systemctl:
systemctl enable sshd.service

How to run a program in SSH?

So I want to run an .exe in SSH but can't figure out, help please?
I'm trying to run a server for my game i'm making and need this on my vps so anyone can connect, but can't figure out how to run it in SSH on my vps.
SSH is a protocol and will, by itself, never run any program. Depending on the Shell you're running inside SSH and the operating system in use you will start your executable:
Linux: ./program
Windows: program.exe
Note: exe usually indicates a Windows program. Most Linux/Unix servers have SSH access, while Microsoft servers usually don't. Are you trying to start a windows exe on a Linux machine? That will not work (ever). Unless it is a .NET executable, in which case you can start in using the mono-framework.
You need ./ before the program name, like this
./program.exe
You want to install an SSH server and make it run your own program instead of the default shell? How to configure that depends entirely on which product / package you are using; but perhaps rephrasing the problem for you is sufficient for helping you find the configuration directive you need in the documentation.
For windows, you can use the following command:
ssh username#remotePcIP "\file.exe"
Linux: This will run a series of commands remotely into a remote machine with ssh (make sure your username has direct access and password is not required):
ssh remotemachine ' command1 | command2 | command3 '

Apache Web Development on Cygwin

I'm trying to get an Apache server running on my Cygwin setup to follow the Java Ranch Cattle Drive tutorials online (basically, to learn Java EE web page development that uses a MySQL back end.)
I used the Cygwin Setup program to install httpd (which is how I installed most other dev tools I use on cygwin) and it says install complete, yet when I run 'httpd' it cannot find the command. It also appears the expected install directory (/usr/local/apache...) doesn't exist.
Does anyone have any experience using this setup, and if so, you could walk me through the initial steps of getting the server up and running and getting a browser to display the server's default page?
To keep answers focused, I didn't want to discus the drawbacks of running Apache on a Windows system - this is just for learning purposes. Thanks in advance.
Looking at the Cygwin Package Listing for httpd, you can see that the executable is installed under /usr/sbin.
So, if /usr/sbin is not on your PATH (it isn't on mine, not by default anyhow), you would actually run:
/usr/sbin/httpd
And btw, if you would like to list the files installed for a certain package, you can use cygcheck:
cygcheck -l httpd
cygrunsrv -I Apache -p /usr/sbin/httpd -a "-X"
This will solve the problem. This assumes you already have cyrunsrv set up. The reason httpd fails with cygrunsrv if you leave out the -X is that the process disconnects from the terminal and cygrunsrv considers that a failure. The -X option for httpd is the debug or terminal mode.
I couldn't find any detailed information on how to get Apache working on Cygwin, so here it is if someone's interested:
Install the httpd-* and httpd-mod_* packages you need. Note that the packages named "Apache" are deprecated. You need the ones named "httpd" (which are actually Apache).
Install cygrunsrv (normally this is a default Cygwin package)
Run /usr/bin/cygserver-config as admin. This is needed because Apache requires an IPC server running.
Open services.msc, then go to the CYGWIN Cygserver. Right-click on it and start it. If you don't do this, you'll probably get errors like "AH00023: Couldn't create the proxy mutex".
Finally, start Apache by running /usr/sbin/apachectl restart
Config is in /etc/httpd/.
Some information about running Apache on Cygwin:
http://httpd.apache.org/docs/1.3/cygwin.html
http://www.issociate.de/board/goto/895433/apache2_does_not_start_in_cygwin.html
http://www.cygwin.com/ml/cygwin-apps/2005-02/msg00085.html
Personally, I would recommend installing WAMPServer or other WAMP stack and do it that way. There is no difference, except that you'll need to control Apache through Windows commands [net start, net stop], not Cygwin's ones.
