I am using winpower to hibernate 2 computers in the event of power failure.
I use the command.
"C:\Program Files\PSTools\psshutdown.exe" -h -t 1 \\COMPUTER -u xxx -p yyy
(with the quotes)
When I use it directly via command line this works fine, but when I use it inside the app it does not work, I suspect a permission issue of some sort.
Can anybody think what the issue might be.

I'm connecting to a windows machine over SSH and would like to launch a GUI app in an existing interactive session.
This should work using psexec -i, but it fails for me in various ways:
psexec -i 1 notepad.exe: notepad crashes without showing UI
psexec -i 1 cmd.exe: I get a black box the size of a cmd.exe window, it never renders. If I look at the window title with "alt-tab", it does say this is an [Administrator] process which is not what I expected.
psexec -i 1 <path to vscode>, it launches successfully but then raises a number of errors related to credential storage.
psexec -s -i 1 cmd.exe: this launches fine, but the process is running as nt authority\system, which is not what I want.
psexec -i 1 -u my_user -p my_pwd <path to vscode>: this works fine, but I can't require passwords and want to use ssh key-based auth instead.
I've seen a ton of questions/answers where it looks like '-i' works for people so I'm not sure what's going wrong here. Any ideas?
It could be due to incorrect session id.
Can you check if the session id is correct, by navigating to users tab in the task manager

I'm trying to connect to my server via SSH and issue some commands to it. For some reason it seems like the commands are getting cut "off".
Here is the code that does the putty connection as well as issuing the SSH commands:
./plink.exe ${USER}#${HOSTNAME} -pw ${PASS}<<SSH
cd /some/foo/bar
deploy_artifact.sh --instance development1 some_artifact.ear
APP_development1.sh restart
exit
SSH
For me it works, but on the machine of my colleague the issued SSH commands are getting cut off and thus are not interpreted correctly. For example deploy_artifact.sh is getting turned into ploy_artifact.sh (See the following the screenshot).
How can i prevent this? And what is causing this?
Thanks in advance for any help!
It appears the problem is with the plink and how it is used. The given example sends commands as a standard input, however I did not find in the plink manual any mention that it reads commands from the STDIN. It is better to avoid undocumented features, since they may not work correctly or the author may remove them without any notice. Instead, if you want to pass commands inline you should provide them as an argument, ie you either have to use a quoted text, or you can wrap heredoc in the "$(cat *heredoc* )" code, eg:
./plink.exe ${USER}#${HOSTNAME} -pw ${PASS} "$(cat <<SSH
cd /some/foo/bar
deploy_artifact.sh --instance development1 some_artifact.ear
APP_development1.sh restart
exit
SSH
)"
Or, you can keep the commands in a file and run the plink with the -m commands_file option.
I had to automate my postgre database backup. As instructed by my software vendor I am trying to use pg_dump.exe (see below) file to take a backup but that prompts me for password.
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
So googled and found that as per "https://www.postgresql.org/docs/9.6/libpq-pgpass.html" I can create a pgpass.conf file within 'C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf" which I did.
Then I tried to pass data of pgpass.conf file to env variable before executing my pg_dump command. But it is not working. Still I am getting prompt to enter password. This is the content of pgpass.conf file: *:*:*:postgres:password
Below is the code I am trying in PowerShell,
$Env:PGPASSFILE="C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf"
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin"
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
Why am I still being asked for password?
When I type following code $Env:AppData I get following response "C:\Users\User1\AppData\Roaming"
Everywhere there are guidance on how to use it in UNIX or command prompt but not in powershell. Any help is appreciated. Also if you could direct me how to secure this password file then it will be great.
With password prompt I cannot automate it with windows task scheduler.
I suspect you have a suitable solution, however, as a quick (and not secure) workaround via the command prompt, you can use the variable PGPASSWORD to hold the password then run the backup script.
A sample might be something like:
SET PGPASSWORD=password
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin" pg_dump.exe -h localhost -p 4432 -U postgres -b -F t -f "d:\qs_backup\QSR_backup.tar" QSR

I have yet to get the damned thing to work yet, but I did find this:
-w
--no-password Never issue a password prompt. If the server requires password authentication and a password is not available by other means
such as a .pgpass file, the connection attempt will fail. This option
can be useful in batch jobs and scripts where no user is present to
enter a password.
I don't see a -w parameter in your call to pg_dump
I used pg_hba file to allow connection "trust" this is riskier method but I had to get things done ASAP. Thank you for your time and effort
I have tectia ssh server in a windows environment.
When I use sftpg3 -B cmd.txt username#host that works fine. The only problem is that it doesnt let me execute files remotely, it only lets me move files. It reads the commands from cmd.txt but since I cant execute anything it ignores the commands.
Well when I do the same thing but use sshg3, it doesnt recognize the -B flag at all.
SSHG3 -B cmd.txt username#host
cmd.txt' is not recognized as an internal or external command,
operable program or batch file.
I've tried putting -B "cmd.txt"
I tried just putting the cmd.txt contents in the same script instead of housing them in cmd.txt and getting rid of -B, but it doesnt run them that way either.
The docs dont have much to go off of. All it says is use -B for batch processing.
Contents of cmd.txt:
D:
cd Library
cd Backup
parseLibrary.cmd
exit
Trying to sshg3 into a host, navigate to a path and run a batch file on that host.
Any ideas?
-B, --batch-mode
Uses batch mode. Fails authentication if it requires user interaction on the terminal.
Using batch mode requires that you have previously saved the server host key on the client and set up a non-interactive method for user authentication (for example, host-based authentication or public-key authentication without a passphrase).
It does use public key authentication, there is no user interaction needed on the terminal.
Noticed this on the docs for sftpg3
-B [ - | batch_file ]
The -B - option enables reading from the standard input. This option is useful when you want to launch processes with sftpg3 and redirect the stdin pipes.
By defining the name of a batch_file as an attribute, you can execute SFTP commands from the given file in batch mode. The file can contain any allowed SFTP commands. For a description of the commands, see the section called “Commands”.
Using batch mode requires that you have previously saved the server host key on the client and set up a non-interactive method for user authentication (for example, host-based authentication or public-key authentication without a passphrase).
I'm guessing batch file is different than batch mode?
*I figured it out. You have to use the -B flag for every command you want to execute.

I'm attempting to launch putty via the command line in such a way that it runs a command on the server (I want to create a windows shortcut, to tail a log file)
So far I have a batch file containing this
"C:\Program Files (x86)\PuTTY\putty.exe" -ssh -t -pw -m tail_catalina_out -load "myprofile"
And within my server I have a file at the root directory named tail_catalina_out with the following contents.
tail -f /opt/tomcat/logs/catalina.out
Putty launches and my session starts successfully, but no command appears to be carried out despite this? Am I misunderstanding how this works?
You don't need -ssh with -load profile (and if you use a nonstandard port like my test it doesn't work at all); in fact you don't need it with [user#]host because it's the default
-pw -m tail_catalina_out uses -m as your password (which I hope is incorrect, so you should be reprompted unless publickey auth is set-up) and ignores tail_catalina_out
the file for -m must be local i.e. on the PuTTY machine not on the server (although the commands in it will be sent to, and must be valid on, the server)
Thus: "\path\to\putty" -t -m localcmdfile -load profile
You could also use plink which runs in the console and takes either -m localfile or the actual remote command on the command line after the last option (like the OpenSSH client ssh):
"\path\to\plink" -t -load profile tail -f remotefile
As usual, you can omit the quotes around the path if it contains no space. Personally I use \progra~2 instead of bothering with "\program files (x86)" but that's just me, and it may depend on a clean install (instead of upgrade).
