• Why does Windows spooler require an administrator account?

  - by Software Monkey

  Does anyone know what changes I might need to make to allow restricted users to print using a printer configured for spooling? My Windows XP SP3 system currently requires me to use an Admin account for printing if the printer is configured to spool documents before printing. If the printer is configured for direct printing it works for all accounts. This used to work and some months back it just stopped, and I can't pin down why. The printer, which is an HP PSC 1200 (an old printer) itself is configured for Everyone to have Print authority and my specific (restricted) account to have Full authority, that is Print, Manage Printers and Manager Documents. My HDD is locked down for restricted users given them only read authority to the entire file system except their data directories, which is how I have run my systems for years. I assume there may be a directory somewhere that I need to allow users to write to.

• CherryPy configuration tools.staticdir.root problem

  - by Alan Harris-Reid

  Hi there, How can I make my static-file root directories relative to my application root folder (instead of a hard-coded path)? In accordance with CP instructions (http://www.cherrypy.org/wiki/StaticContent) I have tried the following in my configuration file: tree.cpapp = cherrypy.Application(cpapp.Root()) tools.staticdir.root = cpapp.current_dir but when I run cherrpy.quickstart(rootclass, script_name='/', config=config_file) I get the following error builtins.ValueError: ("Config error in section: 'global', option: 'tree.cpapp', value: 'cherrypy.Application(cpapp.Root())'. Config values must be valid Python.", 'TypeError', ("unrepr could not resolve the name 'cpapp'",)) I know I can do configuration from within the main.py file just before quickstart is called (eg. using os.path.abspath(os.path.dirname(file))), but I prefer using the idea of a separate configuration file if possible. Any help would be appreciated (in case it is relevant, I am using CP 3.2 with Python 3.1) TIA Alan

• Windows server's HDD Spin down daily/nightly - Does it makes sense?

  - by Riccardo

  A Windows Server 2003 R2 has the following hard disk configuration: - 3 internal hard disks attached to a 3Ware unit, configured in Raid 1 + spare unit - 3 external USB backup disks: 2 Verbatim 1TB (Samsung HD103SI) + 1 Western Digital 1TB (WD10EADS) The server runs 365 days per year, h24, however: - at daytime the server/user usage is limited to the internal hard disks - at nighttime there's no user usage, apart from scheduled maintenance tasks, basically the Server will be idle from 7PM to 8AM. apart from nighly backups (few hours). I was wondering if: (a) it makes any sense let Windows manage power savings, allowing disks to spin down accordingly, ** OR** let the disks stay awlays-on, to avoid permature wearing, due to continuous spin up/down (b) leave internal disks always on, and force external disks to power down while idle (this requires third party tools, such as Verbatim's Green button utility) Your thoughts?

• How to set printer permissions using PowerShell / some other script?

  - by Borek

  I need to update printer's permissions in a script, i.e. do the same as I would manually do this way: Open Devices and Printers applet Double-click the default printer (open its queue) Go to Printer - Properties In the properties dialog, go to Security tab Change permissions for Everyone (e.g., check Manage documents permissions) How to do that? For example, in PowerShell, I can do Get-WmiObject -class win32_printer -filter Default=True to get the default printer and there are then methods getSecurityDescriptor() and setSecurityDescriptor() but for instance this command: (Get-WmiObject -class win32_printer -filter Default=True).getsecuritydescriptor().Descriptor return null so I'm not sure if I'm doing it the right way. Does anyone have a working example to set printer permissions? Am I on the right path or should I use something other than WMI entirely? Thanks.

  I have a EC2 Instance with apchane, PHP and phpmyadmin. I have connect phpmyadmin to manage the aws RDS server. they are in the same security group. But when i try to use a php script to connect to the AWS rds server, it gave me SQLSTATE[HY000] [2003] Can't connect to MySQL server on (xxx.xxx.xxx.xxx). I did some researched, and most of them says use setsebool -P httpd_can_network_connect=1 reference: http://www.filonov.com/2009/08/07/sqlstatehy000-2003-cant-connect-to-mysql-server-on-xxx-xxx-xxx-xxx-13/ But i have no idea which server to configure? and how to?

• "Classic" activity monitor in SQL Server Management Studio 2008?

  - by BradC

  Right now I'm using SQL Server Management Studio 2005 to manage all my SQL servers (2000, 2005, 2008). I'd love to be able to take advantage of all the cool new features in SSMS 2008, the only thing holding me back is the new DMV-based activity monitor: We are still 40% SQL 2000, which doesn't have the required DMVs for the new monitors I don't like it as much as the old one :) So has anyone made a plugin for SSMS 2008 that emulates the old activity monitor? If not, what about a slick set of scripts that accomplish the same thing or better, and work across 2000-2008 (more than just sp_who2)?

• How to stop the Bottle webserver when started from subprocess

  - by luc

  Hello all, I would like to embed the great Bottle web framework into a small application (1st target is Windows OS). This app starts the bottle webserver thanks to the subprocess module. import subprocess p = subprocess.Popen('python websrv.py') The bottle app is quite simple @route("/") def index(): return template('index') run(reloader=True) It starts the default webserver into a Windows console. All seems Ok except the fact that I must press Ctrl-C to close the bottle webserver. I would like that the master app terminates the webserver when it shutdowns. I can't find a way to do that (p.terminate() doesn't work in this case unfortunately) Any idea? Thanks in advance

• Can I use Sikuli as an Jython library in my project?

  - by Yinan

  Sikuli is really cool, but it's working in its buildin Jython environment, the Sikuli IDE. So I m wondering is it possible to import Sikuli as an external library to my Jython library? I saw from Sikuli's website that they have this Python module which provides all Sikuli actions like click and type. Here is the link: http://sikuli.org/documentation.shtml#doc/pythondoc-python.edu.mit.csail.uid.Sikuli.html I have tried importing the skiuli-script.jar and add the skiuli-script/Lib to the PYTHONPATH. Then in my spike.py script, I try to do this: import python.edu.mit.csail.uid.Sikuli capture() #enter to screen capture mode then when execute the script, I got this error: java.lang.UnsatisfiedLinkError: java.lang.UnsatisfiedLinkError: /eclipse_3.4.2/workspace/Jython/src/tmplib/libVDictProxy.jnilib: no suitable image found. Did find: /eclipse_3.4.2/workspace/Jython/src/tmplib/libVDictProxy.jnilib: no matching architecture in universal wrapper I m using Jython 2.2.1 and Mac 10.6.2 (32-bit mode). I have also set to use 32-bit mode first in Java Preference.

• How to maintain one file across many production servers (Windows and Linux)

  - by Brien

  My organization wants to centrally manage an Oracle TNSnames file for all of their production servers. When that file changes, they want to be able to push out the changes to all servers that use it with a minimal effort. Approaches that have been considered: Centralized file server (drawback: if the file server or the network connection to the file server goes down, the servers have no access to the critical file) Subversion client on each server (drawback: using a source control tool in production, added complexity) Store an individual copy of the file on each server (drawback: changing the file contents involves making changes on many different servers) Update Can I use DFS to do this?

• Increasing coverage with try-except-finally and a context-manager

  - by Daan Timmer

  This is the flow that I have in my program 277: try: 278: with open(r"c:\afile.txt", "w") as aFile: ...: pass # write data 329: except IOError as ex: ...: print ex 332: finally: 333: if os.path.exists(r"c:\afile.txt"): 334: shutil.copy(r"c:\afile.txt", r"c:\dest.txt") I've got all paths covered except for from line 278 to line 333 I got a normal happy-flow. I stubbed __builtin__.open to raise IOError when the open is called with said file name But how do I go from 278 to 333. Is this even possible? Additional information: - using coverage.py 3.4 (only listing 3.5, we can't currently upgrade to 3.5)

• Python file-io code listing current folder path instead of the specified

  - by Tom Brito

  I have the code: import os import sys fileList = os.listdir(sys.argv[1]) for file in fileList: if os.path.isfile(file): print "File >> " + os.path.abspath(file) else: print "Dir >> " + os.path.abspath(file) Located in my music folder ("/home/tom/Music") When I call it with: python test.py "/tmp" I expected it to list my "/tmp" files and folders with the full path. But it printed lines like: Dir >> /home/tom/Music/seahorse-gw2jNn Dir >> /home/tom/Music/FlashXX9kV847 Dir >> /home/tom/Music/pulse-DcIEoxW5h2gz This is, the correct file names, but the wrong path (and this files are not either in my Music folder).. What's wrong with this code?

• Can many addon domains slow down cPanel or create problems?

  - by Marco Demaio

  I actually resell hosting plans by using one single cPanel account and many addon domains under it. Basically for each new user I don't create a new cP account, but I simply create a new ADDON domain and give him the necessary space. I know in this way the final user won't be able to manage his emails and he won't be able to access all cPanel features, but that's ok. I know in my account I'm allowed to add unlimited addon domains, but adding many addon domains is there something that might happen that slows down cPanel or could create problems? Any suggestions you could give me about the way i'm using cPanel which might not be the usual way of using it. (As for instance: "be aware that mails from different addon domains under the same CP account could create many problems.", etc.) Thanks!

• GAE datastore eager loading in python api

  - by tomus

  I have two models in relation one-to-many: class Question(db.Model): questionText = db.StringProperty(multiline=False) class Answer(db.Model): answerText = db.StringProperty(multiline=False) question = db.ReferenceProperty(Question, collection_name='answers') I have front-end implemented in Flex and use pyamf to load data. When i try to load all answers with related questions all works as desired and I can access field answer.question however in case of loading questions (e.g. by Questions.all() ), 'question.answers' remains empty/null (though on server/python side I can revise question.answers without problem - probably after lazy-loading). So is it possible to load all questions along with answers ? (I know this is possible in JPA Java api but what about python ?) Shoud I use additional setting, GQL query or django framework to make it work ?

• How to remove ActiveX Add on from IE 7 (normal method does not work)

  - by James

  Hi, Does anybody know how to remove an ActiveX control from Internet Explorer 7.0 ? I had been deleting and adding this control numerous times using the built in delete button in Tools, Manage Add-ons, Enable or Disable. This is required for me to test a downloader ActiveX used for a website. It had always shown up in the "Downloaded ActiveX Controls (32 bit) section of the drop down which activates the delete button. However, all of a sudden it now appears under "Add ons that have been used by Internet Explorer" and I cannot delete it from there. The "in folder" column says it's in the C:\WINDOWS\Downloaded Program Files folder... But it does not appear to be there either... Thanks, James

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.

• Mac OS X pygame input goes to Terminal instead of Python

  - by Parappa

  I'm having trouble running a pygame based app on Mac OS X via Terminal. Input events such as keystrokes go to the Terminal instead of my Python app, and are detected by pygame. For example, I have the following test script: import pygame pygame.init() screen = pygame.display.set_mode((640, 480)) done = False while not done: pygame.event.pump() keys = pygame.key.get_pressed() if keys[pygame.K_ESCAPE]: done = True if keys[pygame.K_SPACE]: print "got here" Neither K_ESCAPE nor K_SPACE will be handled by this script when I run it from a Mac OS X Terminal, but Terminal will echo back the spaces. I'm running the MacPorts port of pygame (py-game), which depends on Python 2.4, and I've also used python_select to make python24 the active version.

• Adding Ubuntu installation to VIsta boot loader

  - by frapfap

  Hi, I had a Vista partition and created a partition and installed Ubuntu 9.10. During the Ubuntu installation I unchecked "Install Boot Loader" so it didn't install the GRUB bootloader. I wanted to keep Vistas boot loader so I could manage it within Vista as I know you can - Ive just forgot where in the Control Panel you do it! Anyway for some reason I incorrectly assumed that the Ubuntu entry would be added to the Vista boot loader. How do enable to choose which OS to use during booting up the computer as at the moment it just automatically loads Vista? Apologies if I'm technically incorrect - what I explained is what I thought was going on!! Thanks.

• metaclass multiple inheritance inconsistency

• Getting packets from one port to another on a Dell PowerConnect 2824 switch

  - by Arvo Bowen

  I have a dell PowerConnect 2824 and I have a cat 5 cable connected from port 1 to port 23. Port 1 is reserved for VLAN 1 (the only VLAN that can manage the switch) and port 18-23 belong to VLAN 112. I currently have the switch setup with ip 10.71.3.5/27 and a test machine plugged into port 22 with IP address 10.71.3.30/27. For some reason I can not ping 10.71.3.5 from my test machine (10.71.3.30). Note: When I try to ping the server plugged into port 21 (IP: 10.71.3.7/27) also VLAN 112, I get responses just fine. Note: When I plug my test machine directly into port 1, I can ping 10.71.3.5 just fine. Quick Recap: Switch IP: 10.71.3.5 Port 1 - dedicated to management - (VLAN1) Port 21 - SERVER (10.71.3.7/27) - (VLAN112) Port 22 - test machine (10.71.3.30/27) - (VLAN112) Port 23 - dedicated to management (to hop over to VLAN 1 from VLAN 112) - (VLAN112)

• Single sign-on for SharePoint to MySite?

  - by Chris W

  I've got a fairly simple SharePoint 2010 farm set up: 2 WFE servers with Network Load Balancing hosting the main portal site. As per Microsoft's best practice recommendations I've set up My Sites in a separate web application. As some of the user base are not using domain joined PCs they have to login once for the portal (http://portal) and then again when the access My Sites since they're crossing in to a separate web application on a separate host (http://mysite). Portal & MySite are both hosted on the same physical WFE servers. Is there an easy way to set up some thing to stop this happening and just have them login once? I understand that there's plans for us to deploy ISA in the not too distant future - could we use ISA to manage authentication to the two sites so that the users only need to log in once?

• Virtual box - How to add disks and move var, opt and home to them?

  - by Jarrod Roberson

  I created a CentOS 5.6 Guest OS Virtual Machine. I made the first disk 10GB, I am rapidly outgrowing it. It was suggested that I make disks for my /var, /opt and /home directories and move them so I can better manage the disks for backing up and what not. This sounds like a good idea. I know how to create the disks in Virtual Box. I have dug around Google and the internet in general and all my attempts at doing this have failed. Snapshots are awesome! I can get the drives fdisked, and I have had limited success mounting them to /mnt/var, /mnt/home and /mnt/opt, but even in single user mode ( init 1 ) I can't get the entire contents of the directories to move over, and then the machine won't reboot correctly. cd /var cp * -ax /mnt/var The /var directory in particular is not wanting to move everything to the new location. How do I format, mount and move the /var, /opt and /home to my new disks?

• How to completely remove a wireless network setup from vista?

  - by 3d1l

  To remove a wireless connection setup I basically go to (network and sharing center) then select (manage wireless network) and then from the list of wireless networks I right click on the one that I want to remove and select (remove network) from the drop down menu. Problem is that when I go to define the wireless network again the system said that the network connection already exist so it seems that even when the wireless network definition is not longer display in the connections list, Vista keeps the configuration somewhere. So How can I be sure that a particular wireless network has been completely removed?

• What are the advantages and disadvantages of having a hosted firewall?

  - by Roy

  Would you rather have your firewall hosted or in house if you've got the skills to manage it? We currently have 6 remote offices and 2 different ISP's, one private network and our firewall (Watchguard, licenses are due to expire) is also our main gateway. I don't see how a hosted firewall (in this case Fortinet) is going to work for us especially when it's cheaper to buy our own firewall and the transition from one ISP to a new provider will take some time because our current contracts aren't due to expire soon. What are to pros and cons of having a firewall hosted by your ISP in general?

• Email attachment problem

  - by Alan Harris-Reid

  Hi there, I want to send an email with an attachment using the following code (Python 3.1) (greatly simplified to show the example) from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText msg = MIMEMultipart() msg['From'] = from_addr msg['To'] = to_addr msg['Subject'] = subject msg.attach(MIMEText(body)) fp = open(att_file) msg1 = MIMEText(fp.read()) attachment = msg1.add_header('Content-Disposition', 'attachment', filename=att_file) msg.attach(attachment) # set string to be sent as 3rd parameter to smptlib.SMTP.sendmail() send_string = msg.as_string() The attachment object msg1 returns 'email.mime.text.MIMEText' object at ', but when the msg1.add_header(...) line runs the result is None, hence the program falls-over in msg.as_string() because no part of the attachment can have a None value. (Traceback shows "'NoneType' object has no attribute 'get_content_maintype'" in line 118 of _dispatch in generator.py, many levels down from msg.as_string()) Has anyone any idea what the cause of the problem might be? Any help would be appreciated. Alan Harris-Reid
