But the webservers at 172.21.37.17 and 172.21.37.24 still didn't respond from the outside world. Although I was able to PPTP VPN in on 321.321.39.10 (interface) which is the outside interface IP address. and it is static mapped to 172.21.37.20. So I'm thinking there must be something wrong with NAT somewhere? no response from 321.321.39.11 to 321.321.39.14.. Could anyone look over the config and please let me know what I've done wrong? Is there something I've missed? well obviously but.. please help! Thank you.

• Multiple Inheritence with same Base Classes in Python

  - by Jordan Reiter

  I'm trying to wrap my head around multiple inheritance in python. Suppose I have the following base class: class Structure(object): def build(self, *args): print "I am building a structure!" self.components = args And let's say I have two classes that inherit from it: class House(Structure): def build(self, *args): print "I am building a house!" super(House, self).build(*args) class School(Structure): def build(self, type="Elementary", *args): print "I am building a school!" super(School, self).build(*args) Finally, a create a class that uses multiple inheritance: class SchoolHouse(School, House): def build(self, *args): print "I am building a schoolhouse!" super(School, self).build(*args) Then, I create a SchoolHouse object and run build on it: >>> sh = SchoolHouse() >>> sh.build("roof", "walls") I am building a schoolhouse! I am building a house! I am building a structure! So I'm wondering -- what happened to the School class? Is there any way to get Python to run both somehow? I'm wondering specifically because there are a fair number of Django packages out there that provide custom Managers for models. But there doesn't appear to be a way to combine them without writing one or the other of the Managers as inheriting from the other one. It'd be nice to just import both and use both somehow, but looks like it can't be done? Also I guess it'd just help to be pointed to a good primer on multiple inheritance in Python. I have done some work with Mixins before and really enjoy using them. I guess I just wonder if there is any elegant way to combine functionality from two different classes when they inherit from the same base class.

• multiple clients - one server connection with sockets tcp/ip c# .net

  - by jagse

  Hello guys, I need to develop a client server system where I can have multiple clients communicating with one server at the same time. I want to communicate xml serialized objects and also need to send and receive other commands to invoke methods. Now, I am just starting with socket programming in C# and .Net and found that the asynchronous I/O is the way to go so that the methods dont block the execution of code. Also there are many examples of how to make a simple client server system. So I have a basic understanding of how that works. Anyway, what still is not clear to me is how I can set up a server which can manage connections to multiple clients? Can I just create a new socket per connection and then store those in some kind of list? Do I need some kind of multiplexing to achieve this? Do I have to listen at multiple ports? What`s the best way here? And the other thing is if I need to develop my own protocol to differentiate between what I am actually sending over the network -- xml serialized object or a command which might be just a string encoded in ascII or something. Or would I develop my own protocol just to send these commands? Any kind of help is apreciated! If someone knows a good book which covers this sort of stuff, let me know. Cheers I forgot to mention that some of my clients which are supposed to communicate with my server will be pda and I therefore use the compact framework... So this might bring in some restrictions...

• How to rename multiple files in multiple folders with 1 command

  - by Charles

  We want to rename our *.html files to *.php but (sadly enough) have not enough knowledge to do it with a dos batchfile and/or cmd prompt command. The problem is that each file is in seperat folder and yes talking about 1500+ different folder names. Using wildcards for the files I know is the '*' but using also a wildcard for folders is unknown to me. We probably need to use the (MSDOS) 'FOR' command but there I am stucked. Folder structure we use is: parent-folder/child-folder/grandchild-folder/file.html sample: games/A/game_name/file.html, games/B/game_name/file.html, games/C/game_name/file.html and so on. The parent folder is for all files the same, the child & grandchild folders are different for most files. After renaming these files to .php I assume following in the .htaccess will make a permanent redirect. RedirectMatch 301 (.).html$ http://oursite.com$1.php Looking forward to suggestions/answers, thnx in advance.

• Multiple Screens, Multiple OS

  Hey, Around two days ago I saw someone working on a computer and alt-tabing to different OSs. Basically he had 3 "screens", one with Fedora, one with Windows XP, one with Mac OSX. How is that possible? I dont think it was a virtual machine.... sounds friggin awesome though.

• Proxmox drbd configuration split brain [on hold]

  - by AudioDan

  I am planning a proxmox HA configuration with two Dell R710 machines (dual 6 core processors in each) with enterprise level drive raid arrays. I would be using DRBD with a quorum disk on a third machine. I would dedicate two 1GB nics on each server to the DRBD communications. We would have approximately 12 to 14 Virtual Machines running on this pair of servers. The proxmox manual recommends creating two DRBD resources - one for the Virtual Machines that normally run on ServerA and one for the Virtual Machines that normally run on ServerB. This is because of the Primary/Primary state in which this configuration runs. If both servers have VMs talking to the same DRBD resource and a split brain situation occurs, there is potential for data corruption that must be resolved. While I understand it would take more effort to create new virtual machines, can anybody foresee any potential problems with running a separate DRBD resource for each VM instead? Does anyone have experience running a setup that way and has it worked well? It seems to me that would allow more flexibility in moving machines back and forth.

• RAID 10 or RAID 5 for multiple VMs - what is the best choice?

  - by Lars Fastrup

  I have just ordered a new rig for my business. We do a lot of software development for Microsoft SharePoint and need the rig to run several virtual machines for development and test purposes. We will be using the free VMware ESXi for virtualization. For a start, we plan to build and start the following VMs - all with Windows Server 2008 R2 x64: Active Directory server MS SQL Server 2008 R2 Automated Build Server SharePoint 2010 Server for hosting our public Web site and our internal Intranet for a few people. The load on this server is going to be quite insignificant. 2xSharePoint 2007 development server 2xSharePoint 2010 development server Beyond that we will need to build several SharePoint farms for testing purposes. These VMs will only be started when needed. The specs of the new rig is: Dell R610 rack server 2xIntel XEON E5620 48GB RAM 6x146GB SAS drives Dell H700 RAID controller We believe the new server is going to make our VMs perform a lot better than our existing setup (2xIntel XEON, 16GB RAM, 2x500 GB SATA in RAID 1). But we are not sure about the RAID level for the new rig. Should we go for having the the 6x146GB SAS drives in a RAID 10 configuration or a RAID 5 configuration? RAID 10 seems to offer better write performance and lower risk of a RAID failure. But it comes at a cost of less drive space. Do we need RAID 10 or would RAID 5 also be a good choice for us?

• Connecting Android device to multiple Bluetooth serial embedded peers

  - by TacB0sS

  I'm trying to find a solution for this setup: I have a single Android device, which I would like to connect to multiple serial embedded devices... And here is the thing, using the "Normal" way to retrieve the Bluetooth socket, doesn't work on all devices, and while it does, I can connect to multiple devices, and send and receive data to and from multiple devices. public final synchronized void connect() throws ConnectionException { if (socket != null) throw new IllegalStateException("Error socket is not null!!"); connecting = true; lastException = null; lastPacket = null; lastHeartBeatReceivedAt = 0; log.setLength(0); try { socket = fetchBT_Socket_Normal(); connectToSocket(socket); listenForIncomingSPP_Packets(); connecting = false; return; } catch (Exception e) { socket = null; logError(e); } try { socket = fetchBT_Socket_Workaround(); connectToSocket(socket); listenForIncomingSPP_Packets(); connecting = false; return; } catch (Exception e) { socket = null; logError(e); } connecting = false; if (socket == null) throw new ConnectionException("Error creating RFcomm socket for" + this); } private BluetoothSocket fetchBT_Socket_Normal() throws Exception { /* The getType() is a hex 0xXXXX value agreed between peers --- this is the key (in my case) to multiple connections in the "Normal" way */ String uuid = getType() + "1101-0000-1000-8000-00805F9B34FB"; try { logDebug("Fetching BT RFcomm Socket standard for UUID: " + uuid + "..."); socket = btDevice.createRfcommSocketToServiceRecord(UUID.fromString(uuid)); return socket; } catch (Exception e) { logError(e); throw e; } } private BluetoothSocket fetchBT_Socket_Workaround() throws Exception { Method m; int connectionIndex = 1; try { logDebug("Fetching BT RFcomm Socket workaround index " + connectionIndex + "..."); m = btDevice.getClass().getMethod("createRfcommSocket", new Class[]{int.class}); socket = (BluetoothSocket) m.invoke(btDevice, connectionIndex); return socket; } catch (Exception e1) { logError(e1); throw e1; } } private void connectToSocket(BluetoothSocket socket) throws ConnectionException { try { socket.connect(); } catch (IOException e) { try { socket.close(); } catch (IOException e1) { logError("Error while closing socket", e1); } finally { socket = null; } throw new ConnectionException("Error connecting to socket with" + this, e); } } And here is the thing, while on phones which the "Normal" way doesn't work, the "Workaround" way provides a solution for a single connection. I've searched far and wide, but came up with zip. The problem with the workaround is mentioned in the last link, both connection uses the same port, which in my case, causes a block, where both of the embedded devices can actually send data, that is not been processed on the Android, while both embedded devices can receive data sent from the Android. Did anyone handle this before? There is a bit more reference here, UPDATE: Following this (that I posted earlier) I wanted to give the mPort a chance, and perhaps to see other port indices, and how other devices manage them, and I found out the the fields in the BluetoothSocket object are different while it is the same class FQN in both cases: Detils from an HTC Vivid 2.3.4, uses the "workaround" Technic: The Socket class type is: [android.bluetooth.BluetoothSocket] mSocket BluetoothSocket (id=830008629928) EADDRINUSE 98 EBADFD 77 MAX_RFCOMM_CHANNEL 30 TAG "BluetoothSocket" (id=830002722432) TYPE_L2CAP 3 TYPE_RFCOMM 1 TYPE_SCO 2 mAddress "64:9C:8E:DC:56:9A" (id=830008516328) mAuth true mClosed false mClosing AtomicBoolean (id=830007851600) mDevice BluetoothDevice (id=830007854256) mEncrypt true mInputStream BluetoothInputStream (id=830008688856) mLock ReentrantReadWriteLock (id=830008629992) mOutputStream BluetoothOutputStream (id=830008430536) **mPort 1** mSdp null mSocketData 3923880 mType 1 Detils from an LG-P925 2.2.2, uses the "normal" Technic: The Socket class type is: [android.bluetooth.BluetoothSocket] mSocket BluetoothSocket (id=830105532880) EADDRINUSE 98 EBADFD 77 MAX_RFCOMM_CHANNEL 30 TAG "BluetoothSocket" (id=830002668088) TYPE_L2CAP 3 TYPE_RFCOMM 1 TYPE_SCO 2 mAccepted false mAddress "64:9C:8E:B9:3F:77" (id=830105544600) mAuth true mClosed false mConnected ConditionVariable (id=830105533144) mDevice BluetoothDevice (id=830105349488) mEncrypt true mInputStream BluetoothInputStream (id=830105532952) mLock ReentrantReadWriteLock (id=830105532984) mOutputStream BluetoothOutputStream (id=830105532968) mPortName "" (id=830002606256) mSocketData 0 mSppPort BluetoothSppPort (id=830105533160) mType 1 mUuid ParcelUuid (id=830105714176) Anyone have some insight...

• Multiple Tables or Multiple Schema

  - by Yan Cheng CHEOK

  http://stackoverflow.com/questions/1152405/postgresql-is-better-using-multiple-databases-with-1-schema-each-or-1-database I am new in schema concept for PostgreSQL. For the above mentioned scenario, I was wondering Why don't we use a single database (with default schema named public) Why don't we have a single table, to store multiple users row? Other tables which hold users related information, with foreign key point to the user table. Can anyone provide me a real case scenario, which single database, multiple schema will be extremely useful, and can't solve by conventional single database, single schema.

• How to Select Multiple Records from Multiple Tables at Once - SQL Server/C#/.NET/T-SQL

  - by peace

  I have two tables Customer and CustomerPhone. Customer usually has multiple phone numbers, so when i run select statement on customer 101, i will get multiple records due to the multiple phone numbers. As you see below all the "Phone" and "Fax" field belongs to CustomerPhone table. These are considered as two records in the CustomerPhone table whereas the rest of fields relate to Customer table which is a single record. What should i do to fill Phone and Fax field in this case? Should i run select statement on CustomerPhone first and then run select statement on Customer?

• SCCM Report to identify machines with 64-bit capable hardware

  - by GAThrawn

  Currently looking at deployment options for Windows 7. One of the questions we're looking into is 32 bit vs 63 bit. I'm trying to run a SCCM report against our estate to identify which machines are 64-bit capable (whether or not they're currently running a 64-bit OS). There seem to be a few resources out on the net for this (here, here and here) but none of them seem to work right on machines running 32-bit Windows XP. 32-bit XP machines seem to always report that they're running on 32-bit hardware. The query I'm currently running is: select sys.netbios_name0, sys.Operating_System_Name_and0 as OperatingSystem, case when pr.addresswidth0=64 then '64bit OS' when pr.addresswidth0=32 then '32bit OS' end as [Operating System Type], case when pr.DataWidth0=64 then '64bit Processor' when pr.DataWidth0=32 then '32bit Processor' end as [Processor Type], case when pr.addresswidth0=32 and pr.DataWidth0=64 then 'YES' end as [32-bit OS on x64 processor] from v_r_system sys join v_gs_processor pr on sys.resourceid=pr.resourceid I've also tried this, which reports all "Windows XP Professional" systems are on "X86-based PC", not x64 based even though a number of them definitely are: select OS.Caption0, CS.SystemType0, Count(*) from dbo.v_GS_COMPUTER_SYSTEM CS Left Outer Join dbo.v_GS_OPERATING_SYSTEM OS on CS.ResourceID = OS.ResourceId Group by OS.Caption0, CS.SystemType0 Order by OS.Caption0, CS.SystemType0 For instance we have a set of Dell Latitude E4200 laptops. Some of these are running 32-bit Windows XP SP3, some of them are running 32-bit Windows 7, some are running 64-bit Windows 7. All the laptops are identical, having come from the same order. Out of these the Windows 7 (32 and 64-bit) report that the hardware is 64-bit capable, and the Windows XP machines report that they're only 32-bit capable. Does anyone know if there's another value I can query to get the hardware's capabilities correctly on XP, or is there a hotfix that will get it reporting the correct info?

• What's the Benefit of Multiple Monitors

  - by DaveDev

  It's become apparent to me that in Software Development it's not uncommon to have more than 1 monitor. We've been pushing for multiple monitors here (currently I have 1 19") but it's difficult to get the point across to the 'deciders' that there would be a benefit. They're only concerned with saving cents. So I thought I'd ask around and see what software developers with multiple monitors thought? What are the benefits? What are the costs? What is the ideal number of monitors for a software developer? Thanks

• Supporting multiple versions without separate builds in JavaME

  - by Casebash

  I want to be able to support multiple versions of Java ME without having to have multiple builds. I already know how to detect the profile/configuration/supported JSRs. My problem is that knowing whether the JSR is supported at run time doesn't allow me to use all the features. For if I call a function added in a later version anywhere in the code - even a location that will never be run, then this will be a compilation error due to static typing. Is there any way round this?

• How to use Vendor Properties in Multiple Backgrounds?

  - by barraponto

  I want to use multiple backgrounds in css, which are currently supported by Firefox 3.61, Chrome/Safari, supposedly Opera10.5 (doesn't run on gnu/linux). It is working fine, however i would like to use linear-gradients as a background. it works ok for Firefox, doesn't work at all with Chrome, yet i can't figure out how to make it work for both at the same time. any clues? http://snook.ca/archives/html_and_css/multiple-bg-css-gradients came the closest to match what i need, but i couldn't get it to work with chrome yet.

• Uploading multiple files simultaneously with Flex

  - by David

  I have been working on a flex uploader, where the user can select multiple files. It works fine when the files are uploaded in a queue (one at a time), however as soon as I try to have it upload 2 files at once I run into issues. It seems that files will often lock up, and either stay at 1% until every other file is uploaded, or just not complete at all. There is never more than one file uploading at a time. Is there some issue with calling .upload on multiple files at once in Flex?

• PHP email form multiple select

  - by Justin Goodman

  I'm trying to set up a simple PHP contact form for a website and I need some help modifying the PHP to list multiple items from a select menu and would appreciate the help. I'm a graphic designer, not a developer, so a lot of this is way over my head. This is the problem area here: <label for="Events[]">Which Event(s) Will You Be Attending?</label> <div class="input-bg"> <select name="Events[]" size="6" multiple="MULTIPLE" class="required" id="Events[]"> <option value="Wednesday">Portfolio Show June 16</option> <option value="Thursday">Portfolio Show June 17</option> <option value="Saturday">Graduation Ceremony</option> <option value="Saturday Eve">Graduation Party</option> <option value="Not Sure">Not Sure</option> <option value="Not Coming">Not Coming</option> </select> </div> And here's the PHP: <?php // CHANGE THE VARIABLES BELOW $EmailFrom = "[email protected]"; $EmailTo = "[email protected]"; $Subject = "Graduation RSVP"; $Name = Trim(stripslashes($_POST['Name'])); $Email = Trim(stripslashes($_POST['Email'])); $Guests = Trim(stripslashes($_POST['Guests'])); $Events = Trim(stripslashes($_POST['Events'])); // prepare email body text $Body = ""; $Body .= "Name: "; $Body .= $Name; $Body .= "\n"; $Body .= "Email: "; $Body .= $Email; $Body .= "\n"; $Body .= "Guests: "; $Body .= $Guests; $Body .= "\n"; $Body .= "Events: "; $Body .= $Events; $Body .= "\n"; // send email $success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>"); // redirect to success page // CHANGE THE URL BELOW TO YOUR "THANK YOU" PAGE if ($success){ print "<meta http-equiv=\"refresh\" content=\"0;URL=http://justgooddesign.net/graduation\">"; } else{ print "<meta http-equiv=\"refresh\" content=\"0;URL=http://justgooddesign.net/graduation/error.html\">"; } ?> Any help really is appreciated!

• Multiple Questions per page using Drupal Quiz

  - by Andrew

  I'm using the Drupal Quiz module, and have setup some basic quizzes and stuff like that. However some further customization is required, involving more than 1 question per page, and a multi-type answer in this type of format: Question 1: Describe 4 things you did last summer a) [ short answer space - text field ] b) "I wept" c) "My whole family died so I learned self reliance" d) "I got another xbox" Question 2: Describe 2 things you hate about yourself a) "My arms are way shorter than my legs" b) "I was born without human emotion" So I guess in two parts, how to show multiple questions per page, and then how to allow multiple text fields for answers. Oh and this quiz is not graded, it's like a self assessment. Thanks!

• Maximizing Adobe Air windows on multiple monitors

  - by Andrew

  In an Adobe Air AJAX application with multiple windows running on a system with multiple (three or more) monitors, can you maximize the windows in each monitor? I've seen posts by others trying to do this, but I've not seen anyone saying how it worked out. I basically need to build a 'status monitor' system (similar to, say, an airport departures monitor) in which there are public-facing displays that need to look and feel like single-purpose, embedded applications -- no window chrome and no visible desktop. I don't think this should be any different from any other windows application, but I don't know about Air. I have a dual-monitor Mac setup right now, but I can't easily test Windows and I likely will never be able to test three monitors at once. This application will be run as an AJAX Air application written in Aptana (or DW if it makes a difference).

• Single database with multiple instances of Django

  - by jwesonga

  I have a Django project where the company will have a main site like www.ourcompany.org and a bunch of sub-domains like project.ourcompany.org. Content appearing in the sub-domains like case studies should also appear in the main site. I've decided to use multiple instances of Django BUT one database for each sub-domain so that I can have some flexibility and take advantage of the Sites framework. What I'm not sure of is how to access the models across the multiple instances. If I have a model: class CaseStudy(models.Model): title=models.CharField(max_length=100) site=models.ManyToMany(Site) Do I need to create this model in every instance so that I can have access to the object?

• What is the risk of introducing non standard image machines to a corporate environment

  - by Troy Hunt

  I’m after some feedback from those in the managed desktop or network security space on the risks of introducing machines that are not built on a standard desktop image into a large corporate environment. This particular context relates to the standard corporate image (32 bit Win XP) in a large multi-national not being suitable for a particular segment of users. In short, I’m looking at what hurdles we might come across by proposing the introduction of machines which are built and maintained by a handful of software developers and not based on the corporate desktop image (proposing 64 bit Win 7). I suspect the barriers are primarily around virus definition updates, the rollout of service packs and patches and the compatibility of existing applications with the newer OS. In terms of viruses and software updates, if machines were using common virus protection software with automated updates and using Windows Update for service packs and patches, is there still a viable risk to the corporate environment? For that matter, are large corporate environments normally vulnerable to the introduction of a machine not based on a standard image? I’m trying to get my head around how real the risk of infection and other adverse events are from machines being plugged into the network. There are multiple scenarios outside of just the example above where this might happen (i.e. a vendor plugging in a machine for internet access during a presentation). Would a large corporate network normally be sufficiently hardened against such innocuous activity? I appreciate the theory as to why policies such as standard desktop images exist, I’m just interested in the actual, practical risk and how much a network should be protected by means other than what is managed on individual PCs.
