I have this code which gives me all of the information I need regarding tasks, information etc. I have it all shelled into a VB program and I want to be able to run this from one computer and have it return the data from all computers on the domain.
I am lost as to what to add next.
Dim sCommand As String
'all processes here, ipconfig, java info, etc etc
sCommand = "java.exe -version2 > C:\Info.txt && ipconfig >> C:\INfo.txt"
Shell("cmd.exe /c" & sCommand)
I have script that will list all users on the domain, can I implement that or is there an easier way?
Edit: If I could search the entire domain for a specific file that would work too.
At the moment I just need all the data returned to a text file, I am not worried about it being sorted, or how long a process like this would take.
thanks a bunch
You could do one of two things.
1) You could use WMI to get both the network config off the remote machines and execute a process on the remote machine.
Or
2) You could use PsExec to kick off a command on a remote machine and pipe that out. I personally wouldn't use shell to execute a command as it's pretty poor really. If I was going to kick off a process locally I'd use this, and use StdOut to grab the output from the shell, parse it to give you something you can work with instead of piping the output to a file locally and then reading it later.
EDIT
So you want to do all this from one central location? If you don't want to use PSExec, you'll have to use WMI to create a process on a remote machine to run the java.exe, but you can't redirect the output, you'll have to pipe to a file and read the file in another step.

I have a single command line windows executable that has many options built into this exe file.
Eg:
(It can take screenshot)
ToolGo.exe printscreen c:\temp\filename.jpg yyyymmdd
(It can show up)
ToolGo.exe showIP machineA
I want to write another command line application, possibly in .net , where it can embed/build a wrapper around this ToolGo.exe file into my application without the user be able to use the ToolGo.exe, and also users can only access one function of this main exe file.
In the example I want this other tool to access only the print screen function in this new exe file.
The new application will have this:
Tool2go.exe printscreen c:\temp\filename.jpg yyyymmdd
But if someone types the following, it will not work:
Tool2go.exe showIP machineA
Or
ToolGo.exe showIP machineA
Any ideas how I can write this code to do this in a .net command line application?
This is a multi-part question, so I'll just give the main part of the issue as the answer with suggestions on handling the rest.
You can embed a .exe into your program by clicking on Properties and navigating the the Resources section, and adding that .exe to it.
After that, it's just a matter of extracting it locally so you can pass your commands to it, and handle it's responses. (I'm not really aware of any way to do so w/out first extracting the. exe; the .exe itself needs to run somehow after all).
To extract the embedded .exe, you do this:
' Extract the MyProgram resource (i.e. your .exe)
Dim b() As Byte = My.Resources.MyProgram
' Write it to the user's Temp folder
File.WriteAllBytes(Environment.ExpandEnvironmentVariables("%TEMP%\MyProgram.exe"), b)
By extracting it to the user's Temp folder, you can pass it your commands, and since it's 'out of sight' the user probably won't even know it's there to directly use it themselves, unless they're a bit more advanced and visit their Temp folder often. You can slightly help to avoid this, but extracting the .exe when your program starts, and then deleting it when it exits, so it only exists on the user's system while your program is running.
As far as what the user can and cannot type in order to pass to the program, you can simply handle the filtering with your program; since your program is the one passing the commands to the .exe, just don't pass any commands that you don't allowed, and pass the ones you do want allowed.
As Part of data Analysis, I need to connect excel macros with unix, fire my shell script from a macro, and get the output file back to excel. I tried using winsock, but it didn't work
This is not a very clear question...
but i suggest to split the problem into parts
test the shell script to make sure it outputs exactly what you want (including carriage returns / whitespace / other fromatting that might confuse Windows or Excel)
test your method of connecting from Windows to Unix. make sure you can run a command from PowerShell which logs in to the unix machine, runs the script, and returns the result
test your Excel macro. ensure it has permission to make the connection you made from PowerShell
You'll have better luck on StackOverflow if you post a piece of code (or network details) and the error message you got from that code.
I'm pretty new to both Taverna and Abaqus but I am trying to run an Abaqus model using a "Tool" in Taverna remotely on a HPC. This works fine if I already have my model file and inputs on the HPC but I need a way of uploading the files dynamically in Taverna (trying to generically wrap Abaqus models).
I've tried adding a input port that takes a file list but I don't know how I can copy it to the "location" that I've set for the tool. Could a beanshell service be the answer or can I iterate through the file list and copy them up before executing the abaqus model?
Thanks
When you say that you created an input port that takes a file list, I guess you mean an input to the tool service.
Assuming the input port is called my_file_list, when the tool service is run, it will take a list of data values on port my_file_list. As an example, say it has "hello", "hi" and "hola" is the three values in the list.
On the location where the tool service is run, it executes in a temporary directory - a different directory for each execution of the service. It is normally something like /tmp/usecase-2029778474741087696
Three files will be created in the temporary directory; those files contain the (in this example) three values the tool service received on port my_file_list. The files could be called
/tmp/usecase-2029778474741087696/tempfile.0.tmp containing hello
/tmp/usecase-2029778474741087696/tempfile.1.tmp containing hi
/tmp/usecase-2029778474741087696/tempfile.2.tmp containing hola
There will also be a file called my_input_list. That file will contain
/tmp/usecase-2029778474741087696/tempfile.0.tmp
/tmp/usecase-2029778474741087696/tempfile.1.tmp
/tmp/usecase-2029778474741087696/tempfile.2.tmp
The script of your tool service would normally read the contents of my_input_list line by line and do something with the contents of the listed file(s).
I have also seen some scripts that 'cheat' and iterate directly over tempfile*.tmp but that would be "a bad thing". The problem with that trick, is that if you want to add a second list of files to the tool service then the file my_input_list could contain
/tmp/usecase7932018053449784034/tempfile.4.tmp
/tmp/usecase7932018053449784034/tempfile.5.tmp
/tmp/usecase7932018053449784034/tempfile.6.tmp
as other temporary files were used for the other file list port.
I hope that helps
The tool service allows you to upload files - but if you are using the HPC through a job submission node, then you would have to modify your command line tool to then use the job file staging command to further push the files as part of the job. The files would be available in the current (temporary) directory of the specified tool script.
I would try to do it through the Tool service and not involve the beanshell - then you can keep your workflow simpler.
A good thing to remember is that you can write multiple shell commands in the box.
Similarly you would probably want to retrieve back the results so that you can process them further in the workflow (unless they are massive - in which case you should just output their remote filenames and send them in again to the next HPC job)
The exact commands to use for staging files and retrieving them depends on the HPC job submission system. Which one are you using?
Thanks for the input guys.
It was my misunderstanding of how Taverna uses the File list. All the files in the list are copied to the temp "sandbox" and are therefore available for use.
Another nice easy way is to zip the directory and pass the zipped files into an input port for the service. Then just unzip the files inside the command.
Thanks again
I am trying to implement an online terminal UI with jsch as backend.
I need to display the userinfo ie [username#Machine ~]$ information in the UI.
Since the outputstream simply sends the bytes, it is difficult to distinguish the userinfo with the real command output. Is there any way to distinguish the same?
In general, no.
If you have a shell channel, all you see is the output from the user's remote shell, including the prompt and the actual command output. You can try to parse that. In simple cases this will work, but in general it is impossible, as every command could output a prompt-like string.
The username should be known to you (it should be the same as you used for login), the server name is a bit trickier.
An idea worth exploring might be to set a special prompt delimited by character sequences which are unlikely to occur in "normal" command output – set the PROMPT variable in your shell.
You could circumvent that problem by not using actually a shell channel, but an individual exec channel for each command – but then you'll have to interpret commands like cd yourself and keep track of the current directory, and add a cd command before the actual command in each exec channel. You might want to have an sftp channel open in parallel to keep track of the directories (and list files, and so on).
I have a .bat file shown below in which I want to redirect the whole contents present in my IDE to some text file.
D:\WindRiver\wrenv.exe -p vxworks653-2.2.3 run
D:\WindRiver\wrenv.exe -p vxworks653-2.2.3>C:\ThreePartition\output.txt
PAUSE
I am able to just get some partial output i.e I am unable to get the errors which are thrown during compilation or building process.
Is this correct or Can anyone suggest any other way??
Thanks a lot
Maddy
You can try this:
D:\WindRiver\wrenv.exe -p vxworks653-2.2.3 > C:\ThreePartition\output.txt 2>&1
You can find a good explanation here. Basically you need to redirect both stdout AND stderr to your file.
Best regards.
Your batch is redirecting all messages from wrenv.exe that are sent to the standard output.
I never used WinRiver but usually IDEs manage the console internally and don't log any messages on the standard output/error stream.
It is maybe possible to set the output of the console of the IDE though. If it is, try to set it to the standard output.
I think you want to combine both those lines into one:
D:\WindRiver\wrenv.exe -p vxworks653-2.2.3 run >C:\ThreePartition\output.txt
OK, looking at your posts here, here and here, it seems you want to log the compilation process. The command for that will be something like (all on one line):
make ThreePartition.mak >C:\ThreePartition\output.txt
Assuming there's a file called ThreePartition.mak.
The command you've been using so far is designed to simply open an interface where you can type commands, which is why you get no output. If you want to log simulation, or a kernel build, there is a file called vxworks_cli_tools_users_guide_6.6.pdf which describes the command line interface, including vxprj in full detail.
Also, are you really using a nant script to call a .vbs to call a .bat to call wrenv.exe? I'm sure there's a simpler way to do that.
