I've been trying to write a powershell script that automates my windows workspace setup and configuration and am currently stuck trying to redirect input to WSL when executing it for the first time. The core of the problem is that Ubuntu's first launch prompts for a username and password, then logs in to a bash shell. I tried writing down the input lines into a text file like so:
Username
Password
Password
exit
Then, I tried redirecting the input of wsl to the file:
Start-Process ubuntu2004.exe -RedirectStandardInput stdin.txt -NoNewWindow -Wait
The above didn't work as executing WSL just starts spamming Enter new UNIX username: adduser: only one or two names allowed. I tried doing same in CMD with the < input redirection, but the result is the same.
This is not exactly the answer to your question, but in my opinion, ansible is better suited for such a task.
I myself recently became interested in assembling a workspace in wsl and ansible seemed to me the best solution.
Before starting the build, you will need to perform minimal steps (create a user and install several packages, all this can be placed in the readme), but then there will be no restrictions.
You can find several ready-made examples of wsl assembly via ansible on github.
A few ideas for setting the username/password in a new Ubuntu WSL instance:
First, a "PowerShell sendkeys" via COM or Interop might work for this. It's probably the closest in behavior to what you are actually asking.
Second, and perhaps most promising, I just tried this with a new Debian WSL installed from the Store (since I didn't want to mess with my Ubuntu install).
When running debian.exe (like ubuntu2004.exe), I let it run the install, then I Ctrl+C'd out of it when it started asking for the default username/password. At that point, the WSL instance is installed, but with only root. I assume that your script can let the command run for a certain period of time, then kill the process to replicate this.
From your script, you should then be able to run wsl -u root useradd --create-home --user-group --groups adm,dialout,cdrom,floppy,sudo,audio,dip,video,plugdev,netdev --password "encryptedPassword" username (see here for creating the encrypted password). I think that will get you a stock Ubuntu user the way that WSL sets it up.
You'll then need to either create a /etc/wsl.conf file (instructions) letting the instance know that that user is the default, or LxRunOffline lists this as one of its features.
But I'd also throw in that you might just want to keep a "backup" of an existing WSL instance that you start from. Do a wsl --export <distroname> <imagename.tgz>, then you can import it when setting up the new Windows host by copying the tgz over and doing a wsl --import <DistroName> <DirectoryWhereYouwantItToLive> <imagename.tgz>.
If you want, you can keep this image up to date with your desired WSL configuration, so that you don't have to recreate it when you rebuild the Windows hosts. That said, this is where I do follow #Mystic's suggestion of using Ansible to store my WSL "configuration as code". It allows me to not only recreate my WSL instances, but also that same configuration when I set (or reset) a Linode host or another Linux system.
I have restrictions on the home directory of my remote machine, is there a way to change where Vscode Remote - SSH puts it's collateral files (~/.vscode, ~/.vscode-server, ...)?
I've looked through all the settings and haven't found anything that looks right
I need the ~/.vscode to be located somewhere besides home folder
I found the active feature request https://github.com/microsoft/vscode-remote-release/issues/472
To get around this for now you can link ~/.vscode-server to another folder/drive
ln -s /path/to/big/disk/.vscode-server ~/.vscode-server
I need to take ownership of a remote registry key across the network in order to delete it but I'm struggling to work out how. PSRemoting is turned off and needing to download additional software etc to do so is untenable (this is part of a toolset script that is used by multiple teams).
Thus far I've tried doing it using REGINI but always get the same error
REGINI: CreateKey (\\computername\HKU\SID\software\microsoft\windows NT\currentversion\windows) relative to handle (000000000) failed - 161
REGINI: Failed to load from file 'acl.txt' (161)
Has anyone else had the need to do this and found a good solution?
Thank you.
Have you tried psexec in conjunction with the regini command?
psexec -s \\computername regini c:\temp\acl.txt
Don't forget to copy the acl.txt to target computer's c:\temp folder.
I had this in my Windows services:
C:/Program Files/PostgreSQL/8.4/bin/pg_ctl.exe runservice -N "postgresql-8.4" -D "D:/PostgreSQL/8.4/data" -w
It never finishes executing. But if I did this on the dos shell:
C:/Program Files/PostgreSQL/8.4/bin/pg_ctl.exe start -N "postgresql-8.4" -D "D:/PostgreSQL/8.4/data" -w
Notice that I only changed the "runservice" to "start" and it works just fine.
Any idea?
The command runservice can only be executed by the service manager
in order to fix my localhost windows 7 to start postgres as a service
i used the following command to start the data
pg_ctl -D "C:\Program Files\PostgreSQL\9.1\data" start
Then checked the status for errors
pg_ctl -D "C:\Program Files\PostgreSQL\9.1\data" status
if you get error 1063 , its more than likely permissions, i executed the following command
cacls "C:\Program Files\PostgreSQL\9.1\data" /E /T /C /G postgres:F
then reran the start/status, it showed everything fine, but still service manager would not start the service
So, in Services->postgresql->options->logon i set the log on as the Local system account instead of the postgres user, and voila it worked
this happened to me because i set my data directory to be somewhere the postgres windows user account didn't have access to.
I had this problem in Windows after a system crash. Running the first command showed invalid data in C:\Program Files\PostgreSQL\9.1\data\postmaster.pid. Deleting that file did the trick. Reference.
I faced the same issue after moving manually the database data files (PG_DATA directory) without recreating all the necessary permissions.
Here is how I solved my issue:
1. Check permissions on old PG_DATA directory:
cacls "c:\path\to\old\pgdata\dir"
2. Check permissions on new PG_DATA directory:
cacls "d:\path\to\NEW\pgdata\dir"
3. Compare outputs from 1. and 2.
Find the differences between users and/or permissions then synchronize them.
Nota: I found it easier to use explorer for the synchronization step rather than using cacls directly from the command line.
If you changed pg_hba.conf , maybe you missed somewhere in file. For example there must be CIDR after IP in that file. It must be like 192.168.1.100/32
If you forgot to put 32, then server doesnt restart.
Investigation of startup logs could be a clue. For the case problem is in the pg_hba.conf you could see something like this:
2018-11-13 00:39:34.841 PST [8284] FATAL: could not load pg_hba.conf
2018-11-13 00:39:34.842 PST [8284] LOG: database system is shut down
You need to check your logfiles and the windows eventlog for some hint of what the problem is. If there is nothing at all there, you need to break out something like Process Monitor and get a stacktrace of where it's hung.
I have had this issue in the past, and it was that the installer did not set up the permissions correctly for the user that the service was to run as.
I've also ran into this problem with postgresql throwing and error after trying to initialize the database cluster. After analyzing the log files and running command line scripts for 4 hours I've got the solution to anyone running into this problem for Windows Versions.
This is not a detailed description as to why its happening. I've installed odoo 10, 11, 12 and 13 numerous times on countless client servers and windows systems and this is the first time I've ever ran into this problem. I cant say if its because I have MS VS Enterprise installed and Android Studio on this machine or what. But Below is the easy answer on how to fix it and initialize the cluster and create the database files in the data folder.
Open the data folder for postgresql. - For Odoo installs it will normally be "C:\Program Files (x86)\Odoo 13.0\PostgreSQL" Unless you chose another location when installing.
Remove any or all files from this folder - If not you will get an error when running initdb.exe
Right click the data folder and open up the properties for it. Click on the Security tab and then click the advanced button on the bottom.
You need to change the owner of this folder to openpgsvc. Click Change and type in openpgsvc and click ok. Once done click the check box below saying that you want this change to affect containers with this container as well.
Then on the Permissions tab click the add button on the bottom. You need to add openpgsvc as a user and give this user full rights. Click apply and and ok to close out of all the folder properties.
Now you need to open cmd.exe - Once open we are going to call initdb.exe and pass some values to it as well.
First run chdir and change the working directory to the location of initdb.exe. For me, running odoo 13 on a windows 10 machine the location is this..
"C:\Program Files (x86)\Odoo 13.0\PostgreSQL\bin"
There is one variable that need to be passed as well to make this work here is the list. NEEDS TO BE INCLUDED IN THE CALL TO initdb.exe
Postgres Data Dir: "C:\Program Files (x86)\Odoo 13.0\PostgreSQL\data"
The End Result with the parameter would look like this for my installation:
"C:\Program Files (x86)\Odoo 13.0\PostgreSQL\bin\initdb.exe" -D "C:\Program Files (x86)\Odoo 13.0\PostgreSQL\data"
Hit Enter and let it rip. The output of this command should look like this below.
Cmd.exe running initdb.exe script
Make sure there is no buggy empty file Program at C:\ like C:\Program
In this case, explorer will warn whenever you log on into Windows.
File Name Warning
-----------------
There is a file or folder on your computer called "C:\Program" which
could cause certain applications to not function correctly. Renaming it
to "C:\Program1" would solve this problem. Would you like to rename
it now?
Installing PostgreSQL 10 On Windows 7 (yes the clock is ticking...). I first tried the latest version 11 which completely failed to install... not a good sign for Windows users. Anyway.
Quick answer: Change the account in the Windows Services panel from Network to Local.
Details of my case
During installation I created/selected a data folder in the user profile folder, because obviously the folder suggested by default, within the program folder, wouldn't work, and if it worked it would be a very idea to put data here (I don't know whether it's usual to do that on Unix/Linux, but for Windows it's it's not allowed for a long time).
At the end (when populating the data cluster) I received an error:
Failed to load SQL Modules into database Cluster
but the installation was able to complete. I found two pages about previous error, here and here, but they didn't seem relevant to my case, so I just started pgAdmin and, on the left "browser", saw the server wasn't active.
I tried to start it from here (had to type the main password), but it went inactive immediately again. So I tried to use the Windows services panel to start "postgresql-x64-10", no joy. I copied the command from this panel and pasted it into a Windows console (cmd.exe) where I finally received this
error 1063.
Searching I found this related question, and was convinced the problem was about permissions.
Solution working for my case
In the services panel I changed the account used to start the service from Network Service to Local System as suggested in a comment by #AlexanderRios.
sc create "postgresql-9.2" binPath= "\"C:/Program Files (x86)/PostgreSQL/9.2/bin/pg_ctl.exe\" runservice -N \"postgresql-9.2\" -D \"C:/Program Files (x86)/PostgreSQL/9.2/data\" -w" DisplayName= "postgresql-9.2" start= auto
Try this on CMD run as Administrator
(Add your parameters depend on your version)
Stop all postgres processes
Go to the postgres data folder (C:\Program Files\PostgreSQL\9.6\data)
Delete the postmaster.opts and postmaster.pid files
From the control panel, in administrative
tools and the services console start the postgres service
open pgAdmin III and then in right pane find server then just right click and connect, enter the password. after connected go to the browser and refresh ODOO. Problem solved.

Is it possible to have a Perl script run shell aliases? I am running into a situation where we've got a Perl module I don't have access to modify and one of the things it does is logs into multiple servers via SSH to run some commands remotely. Sadly some of the systems (which I also don't have access to modify) have a buggy SSH server that will disconnect as soon as my system tries to send an SSH public key. I have the SSH agent running because I need it to connect to some other servers.
My initial solution was to set up an alias to set ssh to ssh -o PubkeyAuthentication=no, but Perl runs the ssh binary it finds in the PATH instead of trying to use the alias.
It looks like the only solutions are disable the SSH agent while I am connecting to the problem servers or override the Perl module that does the actual connection.
Perhaps you could put a command called ssh in PATH ahead of the ssh which runs ssh as you want it to be run.
Alter the PATH before you run the perl script, or use this in your .ssh/config
Host *
PubkeyAuthentication no
Why don't you skip the alias and just create a shell script called ssh in a directory somewhere, then change the path to put that directory before the one containing the real ssh?
I had to do this recently with iostat because the new version output a different format that a third-party product couldn't handle (it scanned the output to generate a report).
I just created an iostat shell script which called the real iostat (with hardcoded path, but you could be more sophisticated), passing the output through an awk script to massage it into the original format. Then, I changed the path for the third-party program and it started working fine.
You could declare a function in .bashrc (or .profile or whatever) with that name. It could look like this (might break):
function ssh {
/usr/bin/ssh -o PubkeyAuthentication=no "$#"
}
But using a config file might be the best solution in your case.
