  I am trying to check a field in some XML that is returned from an outside. The XML is returned in a variable call $out and when you view the source of the page you get a XML output of the following, <?xml version="1.0" encoding="UTF-8"?> <ResponseBlock Live="FALSE" Version="3.51"> <Response Type="AUTH"> <OperationResponse> <TransactionReference>23-9-1334895</TransactionReference> <TransactionCompletedTimestamp>2010-04-30 15:59:05</TransactionCompletedTimestamp> <AuthCode>AUTH CODE:TEST</AuthCode> <TransactionVerifier>AlaUOS1MOnN/iwc5s2WPDm5ggrCLwesUnHs9h+W0N3CRaln2W6lh+6dtaRFFhLdwfnw6y7lRemyJUYl9a3dpWfzORE6DaZkFMb+dIb0Ne1UxjFEJkrEtjzx/i8KSayrIBrT/yGZOoOT42EZ9loc+UkdGk/pqYvj8bZztvgBNo2Ak=</TransactionVerifier> <Result>1</Result> <SettleStatus>0</SettleStatus> <SecurityResponseSecurityCode>1</SecurityResponseSecurityCode> <SecurityResponsePostCode>1</SecurityResponsePostCode> <SecurityResponseAddress>1</SecurityResponseAddress> </OperationResponse> <Order> <OrderInformation>This is a test order</OrderInformation> <OrderReference>Order0001</OrderReference> </Order> </Response> </ResponseBlock> I want check what value is in the 'Result' field.

• On saving an new active record, in what order are the associated objects saved?

  - by Bryan

  In rails, when saving an active_record object, its associated objects will be saved as well. But has_one and has_many association have different order in saving objects. I have three simplified models: class Team < ActiveRecord::Base has_many :players has_one :coach end class Player < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end class Coach < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end I expected that when team.save is called, team should be saved before its associated coach and players. I use the following code to test these models: t = Team.new team.coach = Coach.new team.save! team.save! returns true. But in another test: t = Team.new team.players << Player.new team.save! team.save! gives the following error: > ActiveRecord::RecordInvalid: > Validation failed: Players is invalid I figured out that team.save! saves objects in the following order: 1) players, 2) team, and 3) coach. This is why I got the error: When a player is saved, team doesn't yet have a id, so validates_presence_of :team_id fails in player. Can someone explain to me why objects are saved in this order? This seems not logical to me.

• Processing command-line arguments in prefix notation in Python

  - by ejm

  I'm trying to parse a command-line in Python which looks like the following: $ ./command -o option1 arg1 -o option2 arg2 arg3 In other words, the command takes an unlimited number of arguments, and each argument may optionally be preceded with an -o option, which relates specifically to that argument. I think this is called a "prefix notation". In the Bourne shell I would do something like the following: while test -n "$1" do if test "$1" = '-o' then option="$2" shift 2 fi # Work with $1 (the argument) and $option (the option) # ... shift done Looking around at the Bash tutorials, etc. this seems to be the accepted idiom, so I'm guessing Bash is optimized to work with command-line arguments this way. Trying to implement this pattern in Python, my first guess was to use pop(), as this is basically a stack operation. But I'm guessing this won't work as well on Python because the list of arguments in sys.argv is in the wrong order and would have to be processed like a queue (i.e. pop from the left). I've read that lists are not optimized for use as queues in Python. So, my ideas are: convert argv to a collections.deque and use popleft(), reverse argv using reverse() and use pop(), or maybe just work with the int list indices themselves. Does anyone know of a better way to do this, otherwise which of my ideas would be best-practise in Python?

• How can I use an SSH tunnel for all traffic from a single application, without knowing the ports used?

  - by Matthew Read

  I have an application that opens connections on dozens of ports, and doesn't provide documentation about which ports it uses. I could use Wireshark or something to capture the traffic and export the ports from that, but I think it should be simpler than that. (And I'm not sure I would be able to cover all use cases and ensure the app used every single port it can ever use.) So I'm looking for a way to just say "forward all traffic from this application" (bonus points for all traffic from child processes as well) without needing to worry about specific ports. I'm sure there must be a way, but I couldn't hit on the right keywords while searching Google. How can I do this?

• Network adapters reliability

  - by casey_miller

  Can you help me with understanding of reliability of network adapters. Most of the time servers do have at least 2 NIC's bonded to provide sort of a HA for it. So in case of one NIC fails, the second would still do the job. I wonder which factors work when you use network adapters. I know that, the most important and weakest part of any computer system is: storage (i.e HDD). but how reliable actually network adapters are? There are more expensive ones, and cheaper adapters. In which cases do they actually fail? In what circumstances. May it be a intensive usage of them Time when it's on In your experience how often you found yourself changing NIC's due to their fail? Or just what's the typical lifetime of commodity NIC's? thanks.

• set all apache sites offline with temporary static cached original pages

  - by rubo77

  I would like to set all virtualhosts on my server down for maintenance for some time. The temporary page should contain something like sorry, the page www.xxx.com is down for maintenance. you can see the cached version here: Then the trick: the user should then see the cached page from a cache like googlecache or similar for the requested page as long as the server is down. This would show the correct content on pages, that are static anyway and give the visitor the needed content in many cases, while I can shut down mysql and other services that would usually be needed to show that pages. How can I set a global page on all virtualhosts, that parses the original requested URL through PHP?

• ColdFusion 8 Slow Performance

  - by JoeBob

  We have started a new CF8 app and it is running dog slow. A test where we go around ColdFusion (queries within a database utility) show normal speed (80ms). CF8 returns the same query in something like 60 to 80 seconds! I have been looking online and seeing lots of posts about CF8 and performance problems, but don't get any overall sense of a solution; just lots of people trying things and saying that they didn't have the problem with CF7. We are also seeing instability on the server, and some errors relating to garbage collection and the memory heap. We have a number of other applications running on CF8 and they perform adequately...our programmer is not an expert or a guru, he just plugs away. We have isolated this down to a single query that takes forever to return, so it is not a complicated test. Are there any known CF8 problems or obvious tweaks that we should consider trying? If we have to start over and learn a new environment, I will never make deadline. JoeBob

• Regression testing for firewall changes

  - by James C

  We have a number of firewalls in place around our organisation and in some cases packets can pass through four levels of firewall limiting the flow TCP traffic. A concept that I'm used to from software testing is regression testing, allowing you to run a test suite against a changed application to verify that the new changes haven't affected any old features. Does anyone have any experience or an offer any solutions to being able to perform the same type of thing with firewall changes and network testing? The problem becomes a lot more complicated because you'd ideally want to be originating (and testing receipt) of packets across many machines.

• Dialing into multiple PPP connections on Ubuntu

  - by sharjeel

  I have multiple 3G USB based Modems. I would like them to keep connected simultaneously, NOT necessarily aggregating their bandwidth; a separate intelligent application would manage their utilization effectively. However I am running into problem of setting up proper routes for the ppp0,ppp1 interfaces: when one of them connects, other's entries in the routing table get updated so it is no more usable. If I reconnect the second one, it would override the first one's routing entries. If I do it over and over, sometimes both of them's entries disappear while in rare cases the two work well. I have tried it both using NetworkManager as well as WVDial but issue pops up in both of these. Perhaps both of them use same PPP dialer at the backend and thats why this issue appears. What is the proper solution to make them work together? In the long run, I'd also like them to automatically dial in once USB gets connected.

• What is the best way to use Guice and JMock together?

  - by Yishai

  I have started using Guice to do some dependency injection on a project, primarily because I need to inject mocks (using JMock currently) a layer away from the unit test, which makes manual injection very awkward. My question is what is the best approach for introducing a mock? What I currently have is to make a new module in the unit test that satisfies the dependencies and bind them with a provider that looks like this: public class JMockProvider<T> implements Provider<T> { private T mock; public JMockProvider(T mock) { this.mock = mock; } public T get() { return mock; } } Passing the mock in the constructor, so a JMock setup might look like this: final CommunicationQueue queue = context.mock(CommunicationQueue.class); final TransactionRollBack trans = context.mock(TransactionRollBack.class); Injector injector = Guice.createInjector(new AbstractModule() { @Override protected void configure() { bind(CommunicationQueue.class).toProvider(new JMockProvider<QuickBooksCommunicationQueue>(queue)); bind(TransactionRollBack.class).toProvider(new JMockProvider<TransactionRollBack>(trans)); } }); context.checking(new Expectations() {{ oneOf(queue).retrieve(with(any(int.class))); will(returnValue(null)); never(trans); }}); injector.getInstance(RunResponse.class).processResponseImpl(-1); Is there a better way? I know that AtUnit attempts to address this problem, although I'm missing how it auto-magically injects a mock that was created locally like the above, but I'm looking for either a compelling reason why AtUnit is the right answer here (other than its ability to change DI and mocking frameworks around without changing tests) or if there is a better solution to doing it by hand.

• Windows Service doesn't start process with different credentials

  - by Marcus

  I have a Windows Service, running as a user, that should start several processes under different user credentials. I'm using the following code to start a process: Dim winProcess As New System.Diagnostics.Process With winProcess .StartInfo.Arguments = "some_args" .StartInfo.CreateNoWindow = True .StartInfo.ErrorDialog = False .StartInfo.FileName = "C:\TEMP\ProcessFromService\ProcessFromService\bin\Debug\ProcessFromService.exe" .StartInfo.UseShellExecute = False .StartInfo.WindowStyle = ProcessWindowStyle.Hidden 'Opgave WorkingDirectory kan soms tot problemen leiden, indien betreffende directory 'niet bereikbaar (rechten) is voor opgegeven gebruiker. 'Beter dus om deze niet op te geven. '.StartInfo.WorkingDirectory = My.Computer.FileSystem.SpecialDirectories.Temp .StartInfo.Domain = "" .StartInfo.UserName = "MyUserId" Dim strPassword As String = "MyPassword" Dim ssPassword As New Security.SecureString For Each chrPassword As Char In strPassword.ToCharArray ssPassword.AppendChar(chrPassword) Next .StartInfo.Password = ssPassword .Start() End With The process is correctly started when I use the same credentials as of which the Windows Service is running under. The process is not started, without any error, when I use different credentials. In other words: If the Windows Service is running as UserA then I can start a process running as UserA. If the Windows Service is running as UserB then I can not start a process running as UserA. I have created a test project in which I can reproduce this problem. If you put this project in C:\Temp then the used paths will be correct. You can download this test project here: https://dl.dropboxusercontent.com/u/5391091/ProcessFromService.zip NB: I hope this info is enough to explain it. If you need more info, please let me know and I will add it.

• Java assignment issues - Is this atomic?

  - by Bob

  Hi, I've got some questions about Java's assigment. Strings I've got a class: public class Test { private String s; public synchronized void setS(String str){ s = s + " - " + str; } public String getS(){ return s; } } I'm using "synchronized" in my setter, and avoiding it in my getter, because in my app, there are a tons of data gettings, and very few settings. Settings must be synchronized to avoid inconsistency. My question is: is getting and setting a variable atomic? I mean, in a multithreaded environment, Thread1 is about to set variable s, while Thread2 is about to get "s". Is there any way the getter method could get something different than the s's old value or the s's new value (suppose we've got only two threads)? In my app it is not a problem to get the new value, and it is not a problem to get the old one. But could I get something else? What about HashMap's getting and putting? considering this: public class Test { private Map<Integer, String> map = Collections.synchronizedMap(new HashMap<Integer, String>()); public synchronized void setMapElement(Integer key, String value){ map.put(key, value); } public String getValue(Integer key){ return map.get(key); } } Is putting and getting atomic? How does HashMap handle putting an element into it? Does it first remove the old value and put the now one? Could I get other than the old value or the new value? Thanks in advance!

• item-not-found(404) when trying to get a node using Smackx pubsub

  - by DustMason

  I'm trying to use the latest Smackx trunk to get and then subscribe to a pubsub node. However, openfire just sends me a back an error: item not found (404). I am instantiating the java objects from ColdFusion, so my code snippets might look funny but maybe someone will be able to tell me what I've forgotten. Here's how I create the node: ftype = createObject("java", "org.jivesoftware.smackx.pubsub.FormType"); cform = createObject("java", "org.jivesoftware.smackx.pubsub.ConfigureForm").init(ftype.submit); cform.setPersistentItems(true); cform.setDeliverPayloads(true); caccess = createObject("java", "org.jivesoftware.smackx.pubsub.AccessModel"); cform.setAccessModel(caccess.open); cpublish = createObject("java", "org.jivesoftware.smackx.pubsub.PublishModel"); cform.setPublishModel(cpublish.open); cform.setMaxItems(99); manager = createObject("java", "org.jivesoftware.smackx.pubsub.PubSubManager").init(XMPPConnection); myNode = manager.createNode("subber", cform); And here's how I am trying to get to it (in a different section of code): manager = createObject("java", "org.jivesoftware.smackx.pubsub.PubSubManager").init(XMPPConnection); myNode = manager.getNode("subber"); Immediately upon creating the node I seem to be able to publish to it like so: payload = createObject("java", "org.jivesoftware.smackx.pubsub.SimplePayload").init("book","pubsub:test:book","<book xmlns='pubsub:test:book'><title>Lord of the Rings</title></book>"); item = createObject("java", "org.jivesoftware.smackx.pubsub.Item").init(payload); myNode.publish(item); However, it is the getNode() call that is causing my code to error. I have verified that the nodes are being created by checking the DB used by my openfire server. I can see them in there, properly attributed as leaf nodes, etc. Any advice? Anyone else out there doing anything with XMPP and ColdFusion? I have had great success sending and receiving messages with CF and Smack just haven't had the pubsub working yet :) Thanks!

• sshd: How to enable PAM authentication for specific users under

  - by Brad

  I am using sshd, and allow logins with public key authentication. I want to allow select users to log in with a PAM two-factor authentication module. Is there any way I can allow PAM two-factor authentication for a specifc user? I don't want users - By the same token - I only want to enable password authentication for specific accounts. I want my SSH daemon to reject the password authentication attempts to thwart would-be hackers into thinking that I will not accept password authentication - except for the case in which someone knows my heavily guarded secret account, which is password enabled. I want to do this for cases in which my SSH clients will not let me do either secret key, or two-factor authentication.

• Regular expression either/or not matching everything

  - by dwatransit

  I'm trying to parse an HTTP GET request to determine if the url contains any of a number of file types. If it does, I want to capture the entire request. There is something I don't understand about ORing. The following regular expression only captures part of it, and only if .flv is the first int the list of ORd values. (I've obscured the urls with spaces because Stackoverflow limits hyperlinks) regex: GET.?(.flv)|(.mp4)|(.avi).? test text: GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy match output: GET http: // foo.server.com/download/0/37/3000016511/.flv I don't understand why the .*? at the end of the regex isnt callowing it to capture the entire text. If I get rid of the ORing of file types, then it works. Here is the test code in case my explanation doesn't make sense: public static void main(String[] args) { // TODO Auto-generated method stub String sourcestring = "GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy"; Pattern re = Pattern.compile("GET .?\.flv."); // this works //output: // [0][0] = GET http :// foo.server.com/download/0/37/3000016511/.flv?mt=video/xy // the match from the following ends with the ".flv", not the entire url. // also it only works if .flv is the first of the 3 ORd options //Pattern re = Pattern.compile("GET .?(\.flv)|(\.mp4)|(\.avi).?"); // output: //[0][0] = GET http: // foo.server.com/download/0/37/3000016511/.flv // [0][1] = .flv // [0][2] = null // [0][3] = null Matcher m = re.matcher(sourcestring); int mIdx = 0; while (m.find()){ for( int groupIdx = 0; groupIdx < m.groupCount()+1; groupIdx++ ){ System.out.println( "[" + mIdx + "][" + groupIdx + "] = " + m.group(groupIdx)); } mIdx++; } } }

• Which iptables rule do you think is a 'must have'

  - by Saif Bechan

  I have some basic iptable rules set up now for my vps. Just block everything except some default ports, 80,21,22,443. I do get brute forced a lot. I have heard that iptables is very powerful but I have not seen many use cases. Can you give me an example of a(some) rule(s) you always use and give a small example why. I can not find a general best practice post here on SF, if there is any I would like the link. If this is a duplicate I am sorry and it can be closed.

• Problem when copying array of different types using Arrays.copyOf

• Hashtable with int array as key in java

  - by Niels Hansen

  Hey! I'm trying to make a hashtable in java where the keys are int[], but it dosen't work. I have made a little test program to show my problem: public class test{ public static void main(String[] args){ int[] test0 = {1,1}; int[] test1 = {1,1}; Hashtable<int[], String> ht = new Hashtable<int[], String>(); String s0 = "foo"; ht.put(test0, s0); System.out.println("the result from ht.get(test1)"); System.out.println(ht.get(test1)); System.out.println("the result from ht.get(test0)"); System.out.println(ht.get(test0)); } } My intention is that both ht.get calles should return the same result, since the two arrays are equal, but they dont. Here is the result from running the code: the result from ht.get(test1) null the result from ht.get(test0) foo Am I missing something here or is it just impossible to use int[] as keys in a hastable?

• Setting directory security to allow user and deny all

  - by Rita

  I have winforms app, in which I need to access a secured directory. I'm using impersonation and create WindowsIdentity to access the folder. My problem is writing unit tests to test the directory security; I'd like to a write a code that creates a directory secured to only ONE user, which isn't the current user running the UT (or else the test would be worthless). I know how to add permissions to a certain user, but how can I deny the rest, including admins? (in case the user running the UT is an admin) (will this be a wise thing to do?) DirectoryInfo directoryInfo = new DirectoryInfo(path); DirectorySecurity directorySecurity = directoryInfo.GetAccessControl(); directorySecurity.AddAccessRule(new FileSystemAccessRule("Domain\SecuredUser", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow)); directorySecurity.RemoveAccessRule(new FileSystemAccessRule("??", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Deny)); directoryInfo.SetAccessControl(directorySecurity); This isn't working. I don't know who am I supposed to deny. Domain\Admins, Domain\Administrators, me... No one is being denied, and when I check folder's security - The SecuredUser has access to the folder, but the permissions are not checked, even though I specified FullControl. Basically I want to code this: <authorization> <allow users ="Domain\User" /> <deny users="*" /> </authorization> I was thinking about impersonating UT run with a weak user with no permissions, but this would result in: Impersonate - Run UT - Impersonate - Access folder, and I'm not sure if this is the right design. Help would be greatly appreciated, thank you.

• Azure Table Storage rejects an entity with a Property whose value is an Interface

  - by Andrew B Schultz

  I have a type called "Comment" that I'm saving to Azure Table Storage. Since a comment can be about any number of other types, I created an interface which all of these types implement, and then put a property of type ICommentable on the comment. So Comment has a property called About of type ICommentable. When I try to save a Comment to Azure Table Storage, if the Comment.About property has a value, I get the worthless invalid input error. However, if there is no value for Comment.About, I have no problem. Why would this be? Comment.About is not the only property that is a reference type. For example, Comment.From is a reference type, but the Comment.About is the only property of a type that is an interface. Fails: var comment = new Comment(); comment.CommentText = "It fails!"; comment.PartitionKey = "TEST"; comment.RowKey = "TEST123"; comment.About = sow1; comment.From = person1; Works: var comment = new Comment(); comment.CommentText = "It works!"; comment.PartitionKey = "TEST"; comment.RowKey = "TEST123"; //comment.About = sow1; comment.From = person1; Thanks!

• Downloading a file from a PHP page in C#

  Okay, we have a PHP script that creates an download link from a file and we want to download that file via C#. This works fine with progress etc but when the PHP page gives an error the program downloads the error page and saves it as the requested file. Here is the code we have atm: PHP Code: <?php $path = 'upload/test.rar'; if (file_exists($path)) { $mm_type="application/octet-stream"; header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: public"); header("Content-Description: File Transfer"); header("Content-Type: " . $mm_type); header("Content-Length: " .(string)(filesize($path)) ); header('Content-Disposition: attachment; filename="'.basename($path).'"'); header("Content-Transfer-Encoding: binary\n"); readfile($path); exit(); } else { print 'Sorry, we could not find requested download file.'; } ?> C# Code: private void btnDownload_Click(object sender, EventArgs e) { string url = "http://***.com/download.php"; WebClient client = new WebClient(); client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted); client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged); client.DownloadFileAsync(new Uri(url), @"c:\temp\test.rar"); } private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e) { progressBar.Value = e.ProgressPercentage; } void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e) { MessageBox.Show(print); }
