i am a toddler on Twisted .I am trying to run a Twisted web server using the command
twistd web --resource-script=~/Desktop/step/ecdemo.rpy
assume that my file(ecdemo.rpy) is located on desktop in step folder
the traceback when i visit the page(127.0.0.1:8080/ecdemo.rpy) shows
<type 'exceptions.IOError'>: [Errno 2] No such file or directory: '~/Desktop/step/ecdemo.rpy
however if i run the same file with command
python ecdemo.rpy it runs smoothly.
The program simply renders a get request from an http page
I know it is something basic that i do not know but if you could help me get started i would come up with better problems...
thanks for help.
Your shell didn't expand ~ into your home directory. Try this instead:
twistd web --resource-script ~/Desktop/step/ecdemo.rpy
Notice I removed the = between the option name and its value. This will probably let your shell turn ~ into /home/whoever.

I am trying to configure the spark-submits to use JARs that are stored in artifactory.
I've tried a few ways to do this
Attempt 1: Changing the --jars parameter to point to the https end point
Result 1: 401 Error. Credentials are being passed like so: https://username:password#jfrog-endpoint. The link was tested using wget and it authenticates and downloads the JAR fine.
Error
Attempt 2: Using a combination of --packages --repositories
Result 2: URL doesn't resolve to the right location of the jar
Attempt 3:Using combination of --packages and modified ivysettings.xml (containing repo and artifact pattern)
ivy settings
Result 3: URL resolves correctly but still results in "Not Found"
After some research it looks like the error might say "Not Found" and the it looks like it has "tried" the repo, it could still very well be a 401 error.
Error
Any ideas would be helpful! Links i've explored:
Can i do spark-submit application jar directly from maven/jfrog artifactory
spark resolve external packages behind corporate artifactory
How to pass jar file (from Artifactory) in dcos spark run?

You can use https://username:password#jfrog.com/rep, however you need to specify port.
https://username:password#jfrog.com:443/repo
I discovered this using Artifactory's "set me up" tool for package type Ivy. If you look in the resolver url it specifies the port.
I'm trying to add torrents to transmission from python. The code is shown below...
def download_movie(magnet_link):
os.system('transmission-gtk')
#webbrowser.open(magnet_link)
os.system('transmission-gtk ' + magnet_link)
As you can see I've tried 3 different options to add these torrents but none work.. I've also added XDG_RUNTIME_DIR="/run/user/1000" in the crontab file. The log in /var/mail is running the script but it shows: (transmission-gtk:14091): Gtk-WARNING **: cannot open display:. I've also run the command xhost + as said in http://www.thegeekstuff.com/2010/06/xhost-cannot-open-display/ but still the gtk-warning comes up. Anyone have any ideas? What I want eventually is that I run this script on a pi so if anyone has any alternatives, I'm all ears.. Thanks.
It's because you are trying to use GUI app where console one would be appropriate.
See man transmission-remote for details:
DESCRIPTION
transmission-remote is a remote control utility for transmission(1) and transmission-daemon(1).
I am uploading a file from a collection of different servers to one data server. I am using psftp and one out of 20+ servers is producing a permissions problem.
Remote working directory is /
psftp> cd Remote_Directory\
Remote directory is now /Remote_Directory/
psftp> put C:\folders\containing\file\FILE.zip
/Remote_Directory/: open for write: failure
psftp> quit
It appears like a permissions issue on the remote directory, however, why am I only getting the issue on one server? The batch is identical on all of the 20+ servers.
PUT command expects a file name at the end of the destination location.
Please try the following code
put C:\folders\containing\file\FILE.zip /Remote_Directory/FILE.zip
The path in the error message is an exact path to the remote file the psftp tried to create. See outfname in below code snippet:
req = fxp_open_send(outfname,
SSH_FXF_WRITE | SSH_FXF_CREAT | SSH_FXF_TRUNC,
&attrs);
...
printf("%s: open for write: %s\n", outfname, fxp_error());
As the path is obviously not correct (lacks file name), it seems that psftp got confused somehow. I believe it's likely due to wrong (back)slash you have used in the cd command.
Try cd Remote_Directory/.
In my case, it's a permission issue on the remote server, i.e. the account you are using to log on doesn't have the write permission for the remote folder.
Trying to run the opentripplanner and using the Graph.obj to run it for a country.
But whenever trying to run the server it is giving the filenotfound exception at location /otp/Graph.obj although i have put the Graph.obj in the same location.
Stacktrace while running the server is :
Graph file not found or not openable for routerId '' under file:/otp
java.io.FileNotFoundException: /otp/Graph.obj (No such file or directory)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.(FileInputStream.java:146)
at java.io.FileInputStream.(FileInputStream.java:101)
at sun.net.www.protocol.file.FileURLConnection.connect(FileURLConnection.java:90)
I had the same problem trying to run OTP.
First problem: the routerId is missing
Second problem: the default directory is /var/otp/graph and OTP seems to search the graph under /var/otp/graph/{routerId}
Third problem (may not be yours): I tried to run OTP in Cygwin (Windows) and probably there was some trouble with the slashes/backslashes, so I decided to copy the graph under a "../gtfs/gurgaon"
Solution:
Step 1) create a subdirectory like "/var/otp/graph/gurgaon" and copied Graph.obj over there
Step 2) run something like: $ java -jar target/otp.jar --router gurgaon --graphs ../gtfs --server
It worked like a charm for me!
Try this code: java -Xmx5G -jar target/otp-0.20.0-SNAPSHOT-shaded.jar --build path your gtfs and osm.pbf files --inMemory
It worked perfect for me.
I need some Powershell advice.
I need to install an application's MSP update file on multiple Win08r2 servers. If I run these commands locally, within the target machine's PS window, it does exactly what I want it to:
$command = 'msiexec.exe /p "c:\test\My Application Update 01.msp" REBOOTPROMPT=S /qb!'
invoke-wmimethod -path win32_process -name create -argumentlist $command
The file being executed is located on the target machine
If I remotely connect to the machine, and execute the two commands, it opens two x64 msiexec.exe process, and one msiexec.exe *32 process, and just sits there.
If I restart the server, it doesn't show that the update was installed, so I don't think it's a timing thing.
I've tried creating and remotely executing a PS1 file with the two lines, but that seems to do the same thing.
If anyone has advice on getting my MSP update installed remotely, I'd be all ears.
I think I've included all the information I have, but if something is missing, please ask questions, and I'll fill in any blanks.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
My process for this is:
Read a CSV for server name and Administrator password
Create a credential with the password
Create a new session using the machine name and credential
Create a temporary folder to hold my update MSP file
Call a PS1 file that downloads the update file to the target server
>>> Creates a new System.Net.WebClient object
>>> Uses that web client object to download from the source to the location on the target server
Call another PS1 file that applies the patch that was just downloaded –>> This is where I’m having issues.
>>> Set the variable shown above
>>> Execute the file specified in the variable
Close the session to the target server
Move to the next server in the CSV…
If I open a PS window and manually set the variable, then execute it (as shown above in the two lines of code), it works fine. If I create a PS1 file on the target server, containing the same two lines of code, then right click > ‘Run With PowerShell’ it works as expected / desired. If I remotely execute my code in PowerGUI, it returns a block of text that looks like this, then just sits there. RDP’d into the server, the installer never launches. My understanding of the “Return Value” value is that “0″ means the command was successful.
PSComputerName : xx.xx.xx.xx
RunspaceId : bf6f4a39-2338-4996-b75b-bjf5ef01ecaa
PSShowComputerName : True
__GENUS : 2
__CLASS : __PARAMETERS
__SUPERCLASS :
__DYNASTY : __PARAMETERS
__RELPATH :
__PROPERTY_COUNT : 2
__DERIVATION : {}
__SERVER :
__NAMESPACE :
__PATH :
ProcessId : 4808
ReturnValue : 0
I even added a line of code between the variable and the execution that creates a text file on the desktop, just to verify I was getting into my ‘executeFile’ file, and that text file does get created. It seems that it’s just not remotely executing my MSP.
Thank you in advance for your assistance!

Here's the strategy I used to embed an msp into a powershell script. It works perfectly for me.
$file = "z:\software\AcrobatUpdate.msp"
$silentArgs = "/passive"
$additionalInstallArgs = ""
Write-Debug "Running msiexec.exe /update $file $silentArgs"
$msiArgs = "/update `"$file`""
$msiArgs = "$msiArgs $silentArgs $additionalInstallArgs"
Start-Process -FilePath msiexec -ArgumentList $msiArgs -Wait
You probably don't need to use the variables if you don't want to, you could hardcode the values. I have this set up as a function to which I pass those arguments, but if this is more of a one-shot deal, it might be easier to hard-code the values.
Hope that helps!
using Start-Process for MSP package is not a good practice because some update package lockdown powershell libs and so you must use WMI call
