I'm trying to execute a batch file(shutdown.bat and startup.bat of tomcat 7) on a remote machine(Windows server 2008) using PSTools but didn't got any luck till now.
Below are the steps I used
c:\>psexec \\129.12.3.1 -u Admin -p admin90 C:\>Hyp\tom7_50080\bin\shutdown.bat
and on my cmd i got
PsExec v2.0 - Execute processes remotely

PsExec could not start cmd on 129.12.3.1:
There are currently no logon servers available to service the logon request.
Can anyone help with the above output and with the batch file for executing the shutdown and startup batch file on remote machine.
Is PS Tools only option to execute any service/batch file on remote machine or we could use any other utility provided by MS.
In you example, #David Candy pointed out even you had the connection go thru, it would not work as you have 'c:>hyp\' instead of C:\hyp\tom7_*
You seem to be using IP, but the message you got seems to be name resolution related, so not sure what's happening there. Maybe you should upgrade to the latest PsExec version.
If you want to use PowerShell you would use Invoke-Command -ComputerName {NameOfPC} -ScriptBlock {C:\Hyp\tom7_50080\bin\shutdown.bat}
If you want to execute a program on another server, you can use a stored procedure on that server to invoke the command, and call that stored procedure from the local mcahine.
You could also create a web service on the remote server that invoked the command you want to execute.
In either case, be very careful that you don't open a security hole by either allowing more users to execute commands through the mechanism you implement, or by some user to execute commands other than the one you intend.

I normally run an SSIS package using a Sql Agent Job and a proxy user as described here: https://www.sqlservercentral.com/articles/run-an-ssis-package-under-a-different-account
I now need to run the same package using the same proxy user using T-SQL. I've been trying to use the [catalog].[create_execution] and [catalog].[start_execution] procedures to do this but there doesn't seem to be a way to specify a user.
How do I execute a package as a different user?
Is my best recourse the use of T-SQL to execute a SQL Agent Job that is configured to use the proxy user instead?
I don't know how agent actually works to make proxy users work - especially with regard to SSIS packages.
In a "normal" sql session say in SSMS, if I wanted to run a query as another user
EXECUTE AS USER = 'TurgidWizard';
SELECT USER_NAME() AS WhoAmI;
REVERT;
That code would allow me to impersonate you until I hit the REVERT call.
But, if you swap out calls to create_execution/start_execution you'll run into the same issue as trying to use a local sql server user runs into with using the methods in the SSISDB - it doesn't work. The methods in the SSISDB all run checks before they begin to ensure users have the correct access level and there isn't impersonation going on. Because once those methods start running, they themselves do impersonation so I guess that doesn't work well.
How can I run a package using tsql under a different account? I would start SSMS/sqlcmd under the credentials using RUNAS For example, the following will open a new command window as you.
runas /netonly /user:corpdomain.com\turgiwizard "cmd"
From there, things I do will be under the aegis of your user so I could run sqlcmd calls like
sqlcmd -S TheServer -d SSISDB -Q "EXECUTE catalog.create_execution ...;"
Mouse click will be Ctrl+Shift+right click executable.
Your SSMS install location is version dependent but try various ten digit increments of 140 in the following path
C:\Program Files (x86)\Microsoft SQL Server\140\Tools\Binn\ManagementStudio\Ssms.exe
The downside for me with regard to runas is that I could not automate getting my credentials passed into it. I've seen articles about use auto hot key and such but never had any luck with it.
Cleanest/easiest approach for something that needs to run regularly is to use sql agent with a proxy, or you could use Windows Task Scheduler and create it as the target user. One off executions, I'd likely use the runas approach.
I need to setup a scheduled task to flush my Redis DB daily. In order to do this I was planning to create a batch file with commands to connect to my remote Redis Server and flush my specific DB, and then setup the Batch file in a scheduled task.
Currently I have
"%REDIS_PATH%\redis-cli" -h "serverName.somelocation.windows.net" -p 6380 -a SOMEPASSWORD ping
I was expecting this to return PONG, and then continue on from there to add the specific commands for flushing my DB. However, the ping command spins for a few seconds then returns nothing. No error or message or anything. Any help would be greatly appreciated!
UPDATE: I have found a solution to my original problem. I have switched over to using a powershell script instead of a batch file. Someone from Microsoft published the script to flush remotely here: https://aaronsaikovski.wordpress.com/2015/05/18/how-to-flush-the-azure-redis-cache-with-powershell/
Are you running this command locally?
If so, it sounds like port 6380 on your remote machine isn't open to the public. This is probably a good thing.
You should run this command on the command line of the remote machine. You might be able to leave off the host entirely.
I am running an AWS Windows 2012 EC2 instance that has to run 24/7. On this instance, I run a Python 3.6 scraper script and to prevent me from having to regularly check up on the server whether the file is running, I have a .bat file in the shell:startup folder of my instance, that automatically restarts it on a daily base. The .bat file works as it will run the Python script and set a timer to restart/reboot the instance after (t=86400). The .bat file runs on the EC2 instance itself.
However, what the file does not do is run automatically after the reboot. I now first have to remote connect to the server before the .bat file will run. What I want it to do is run without me having to first remote connect into the server. How can I achieve this?
I use the following code in my .bat file. Located on my EC2 instance.
#ECHO OFF
START CMD /K (
CD C:/Users/Administrator/Documents/
python scraper.py
)
START CMD /K SHUTDOWN -t 86400 -r -f
I have tried looking into using AWS' Automations and other schedule based methods but couldn't get that to work.
If you want to use something native to Windows Server 2012, look at Schtasks -- this is more or less the Windows equivalent of cron.
I found the answer to my question by using Task Scheduler and looking at the following article: Run a batch file with Windows task scheduler
An important note here is that for my batch file to run I had to create a task that started CMD and run the batch file from there. Asking Task Scheduler to run the batch file directly doesn't work on Windows Server 2012. I ran the task with the following details:
Administrator account
"Run whether user is logged on or not"
"Run with the highest privileges"
"Start on system start-up"
Action: Start a program -> CMD
Add arguments (optional): /c start "" "C:\Users\Administrator\Desktop\file.bat"
More information on how to do this can be found in this answer: https://stackoverflow.com/a/27055435/7736676
I'm writing a perl script in which I've to shutdown my mssql server ,do some operation and then I've to restart it.I know 1 way is to use netstat to stopt the service but I cann't use that. So I tried installing DBI and DBD::ODBC module.
More info here :Shutdown MSSQL server from perl script DBI
But when I trying to shutdown my server using this command
$dbh->prepare("SHUTDOWN WITH NOWAIT ");
It's not working for me :
I got this response from the community
SHUTDOWN permissions are assigned to members of the sysadmin and serveradmin fixed server roles, and they are not transferable. I'd consider it unlike(hopefully) that perl is run with this rights.
So please tell me is there a way to run the above command as these users ? or what can I do other than this . Note that I have a constraint tha tI cann't simply stop it as windows service.
If the scripts are executed through a web browser then the user executing the scripts will be defined by the web server. It will probably not be a good idea to fiddle with this user. Just leave things as they are.
What you can do is to create a Perl script that is being run by a privileged user on a consistent basis with CRON.
This script being run by CRON can check for specific content like a file which has been written by a script where the user executing the script has lesser privileges.
So the way it could work is as follows:
You execute browser.cgi through a browser to do a specific task.
browser.cgi writes instructions to a file.
Every 1 minute priveleged.cgi executes via CRON. (The root user could execute priveleged.cgi)
priveleged.cgi reads the file browser.cgi has written for instructions and starts and stops services according to the instructions.
I've been trying to set up a schedule to run a stored procedure every hour in Windows Task Scheduler (as I'm using SQL Express and can't install 3rd party tools) but after trying various methods such as running a .bat file from task scheduler, opening SqlCmd utility from task scheduler and passing either the command line syntax or a .sql script file I'm having no luck.
I know this can be done and therefore I'm sure it's something I've missed but if anyone can share their experience of this I'd very much appreciate it.
The following command is in the batch file...
sqlcmd -E -i"C:\Users\Administrator\Desktop\test.sql" -o"C:\Users\Administrator\Desktop\dump.txt"
Thanks a lot
If you are an admin on the sql instance (Since you are using SQLExpress I bet you are trying to do this on your own computer so there is a high chance your user is an admin of the sql instance) you should not use -E at all, just ignore it.
Second, specify the server even if you are working on local.
Start with a simple sql command like below:
sqlcmd.exe -S "." -d MY_DATABASE -Q "SELECT * FROM MY_TABLE"
Replace MY_DATABASE and MY_TABLE with your dbname and table name. Make sure you can run it from command line. It should return the data from your table. (Beware command line options are case-sensitive so -s is not same as -S)
Last, do not try to feed parameters through task scheduler. Put the command with all parameters in a .bat file and just run the batch from task scheduler.
I have recently had a similar issue and my experience may assist you. I was calling a small app i.e. EXE from a batch file. I was scheduling the batch file to run from the Windows Task Scheduler. The app was accessing the SQL data using Windows Authentication.
I could run the app directly i.e. click on the EXE to run it.
I could run the app from the batch file.
But if I tried to run the scheduled task it seemed to start but did nothing and posted no errors that I could find.
I found if I changed the app to run with SQL Authentication it could be run from the Task Scheduler.
I suspect there is something about the context of the Windows Authentication when it is run from Task Scheduler that is not recognised by SQL.
