  • Subnet address in apache access log

    - by m0ntassar
    I was inspecting my apache access logs(I use default combined log format) and I came a cross a wired entry 69.171.247.0 - - [22/Oct/2012:18:15:20 +0200] "GET /some site resources HTTP/1.1" 404 514 "-" "facebookexternalhit/1.0 (+http://www.facebook.com/externalhit_uatext.php)" As u see, this query come from a facebook robot that extract objects from site when somebody post a link. What I find weird is the logged ip address : 69.171.247.0 Does anybody know how is that possible ?

  • Why is Linux choosing the wrong source ip address

    and what to do to let it choose the right one? This all happens inside an OpenVZ container: The Host is Debian/Wheezy with Redhat/OpenVZ Kernel: root@mycl2:~# uname -a Linux mycl2 2.6.32-openvz-042stab081.5-amd64 #1 SMP Mon Sep 30 16:40:27 MSK 2013 x86_64 GNU/Linux The container has two (virtual) network interfaces.

But according to man ip-route the src parameter should only set the source-ip if this route is chosen. But if this route is chosen then the source-ip would be that anyway.

  • getting autodiscover URL from Exchange email address

    - by Anthony
    I'm starting with an address for an Exchange 2007 server: [email protected] And I attempted to send an autodiscover request, as documented at MSDN. I attempted to use the generic autodiscover address documented at the TechNet White Paper. So, using curl on PHP, I sent the following request: <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/requestschema/2006"> <Request> <EMailAddress>[email protected]</EMailAddress> <AcceptableResponseSchema> http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a </AcceptableResponseSchema> </Request> </Autodiscover> to the following URL: https://domain.exchangeserver.org/autodiscover/autodiscover.xml But got no response, just an eventual timeout. I also tried: https://autodiscover.domain.exchangeserver.org/autodiscover/autodiscover.xml With the same result. Now, since my larger goal is to use Autodiscover with Exchange Web Services, and since all of the EWS URLs start with the same sub-domain as the Outlook Web Access address, I thought I'd give that a try: OWA: https://wmail.domain.exchangeserver.org So I tried: https://wmail.domain.exchangeserver.org/autodiscover/autodiscover.xml And sure enough, I got back the expected response. However, I only knew the OWA sub-domain because it's the server I have access to and that I'm using to test everything. I would not know it for sure or be able to guess it if this were a live app and the user was entering in their own Exchange email. I know that whatever generic autodiscover settings must be turned on, because I can enter: [email protected] into Apple Mail on Snow Leopard and it finds everything without trouble. So the question is... Should https://domain.exchangeserver.org/autodiscover/autodiscover.xml have worked, and I just missed a step when trying to connect to it? Or, Is there some trick (maybe involving pinging the email address?) that Apple Mail and other clients use to resolve the address to the OWA subdomain before sending the autodiscover request? Thanks to anyone who knows or can take a wild guess.

  • Google maps sometimes does not return a geocoded value for string

    - by XGreen
    Hi Guys, I have the following code: It basically looks into a HTML list and geocodes and markets each item. it does it correctly 8 out of ten but sometimes I get an error I set for show in the console. I can't think of anything. Any thoughts is much appreciated. $(function () { var map = null; var geocoder = null; function initialize() { if (GBrowserIsCompatible()) { // Specifies that the element with the ID map is the container for the map map = new GMap2(document.getElementById("map")); // Sets an initial map positon (which mainly gets ignored after reading the adderesses list) map.setCenter(new GLatLng(37.4419, -122.1419), 13); // Instatiates the google Geocoder class geocoder = new GClientGeocoder(); map.addControl(new GSmallMapControl()); // Sets map zooming controls on the map map.enableScrollWheelZoom(); // Allows the mouse wheel to control the map while on it } } function showAddress(address, linkHTML) { if (geocoder) { geocoder.getLatLng(address, function (point) { if (!point) { console.log('Geocoder did not return a location for ' + address); } else { map.setCenter(point, 8); var marker = new GMarker(point); map.addOverlay(marker); // Assigns the click event to each marker to open its balloon GEvent.addListener(marker, "click", function () { marker.openInfoWindowHtml(linkHTML); }); } } ); } } // end of show address function initialize(); // This iterates through the text of each address and tells the map // to show its location on the map. An internal error is thrown if // the location is not found. $.each($('.addresses li a'), function () { var addressAnchor = $(this); showAddress(addressAnchor.text(), $(this).parent().html()); }); }); which looks into this HTML: <ul class="addresses"> <li><a href="#">Central London</a></li> <li><a href="#">London WC1</a></li> <li><a href="#">London Shoreditch</a></li> <li><a href="#">London EC1</a></li> <li><a href="#">London EC2</a></li> <li><a href="#">London EC3</a></li> <li><a href="#">London EC4</a></li> </ul>

  • Windows 7 search does not return results from indexed folders

    - by Dilbert
    I am experiencing this issue over and over again and I just cannot seem to find the answer. It doesn't make sense, but search simply does not return results from folders that certainly have these files inside. It's weird that this technology exists for more than 5 years now (it could be added to Windows XP as an addon), and they still haven't got it right. My folder contains 10 image files with .png extensions. Two scenarios: Scenario 1: I exclude the folder using Indexing options. Search works. Scenario 2: I turn on indexing for this folder. Search does not work. Of course, Agent Ransack returns results every time. When I check Advanced options for the Indexing options inside control panel, .png files are checked in the File Types tab, using the "File Properties filter". What's the deal with this? [Edit] To clarify, this doesn't happen with all folders, but does with more than one. For the "problematic" folders, even *.* doesn't return a single result. I found some advice to clear the archive and readonly attributes for all files (doesn't make sense, but hey), but it didn't work. Indexing status in Control panel is: Indexing complete. 100,000 items indexed. Folder is included in the list. File types list contains the .png extension (although it doesn't work with any filter, not even *.*).

  • Fetching data (responsebody) with a HttpClient in an AsyncTask and returning the data outside the As

    - by Peter Warbo
    Basically I'm wondering how I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results. What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content). This is what my code looks like simpliefied with the most important parts (I think). public class activity extends Activity { private String responseBody; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initControls(); } public void initControls() { fieldSearch = (EditText) findViewById(R.id.EditText01); buttonSearch = (Button)findViewById(R.id.Button01); buttonSearch.setOnClickListener(new Button.OnClickListener() { public void onClick (View v){ search(); }}); } public void grabURL(String url) { new GrabURL().execute(url); } private class GrabURL extends AsyncTask<String, Void, String> { private final HttpClient client = new DefaultHttpClient(); private String content; private boolean error = false; private ProgressDialog dialog = new ProgressDialog(activity.this); protected void onPreExecute() { dialog.setMessage("Getting your data... Please wait..."); dialog.show(); } protected String doInBackground(String... urls) { try { HttpGet httpget = new HttpGet(urls[0]); ResponseHandler<String> responseHandler = new BasicResponseHandler(); content = client.execute(httpget, responseHandler); } catch (ClientProtocolException e) { error = true; cancel(true); } catch (IOException e) { error = true; cancel(true); } return content; } protected void onPostExecute(String content) { dialog.dismiss(); if (error) { Toast toast = Toast.makeText(activity.this, getString(R.string.offline), Toast.LENGTH_LONG); toast.setGravity(Gravity.TOP, 0, 75); toast.show(); } else { activity.this.setResponseBody(content); } } } public void search() { String query = fieldSearch.getText().toString(); String url = "http://example.com/example.php?query=" + query; //this is just an example url, I have a "real" url in my application but for privacy reasons I've replaced it grabURL(url); // the method that will start the asynctask processData(responseBody); // process the responseBody and display stuff on the ui-thread with the data that I would like to get from the asyntask but doesn't obviously }

  • LINQ 4 XML - What is the proper way to query deep in the tree structure?

    - by Keith Barrows
    I have an XML structure that is 4 deep: <?xml version="1.0" encoding="utf-8"?> <EmailRuleList xmlns:xsd="EmailRules.xsd"> <TargetPST name="Tech Communities"> <Parse emailAsList="true" useJustDomain="false" fromAddress="false" toAddress="true"> <EmailRule address="@aspadvice.com" folder="Lists, ASP" saveAttachments="false" /> <EmailRule address="@sqladvice.com" folder="Lists, SQL" saveAttachments="false" /> <EmailRule address="@xmladvice.com" folder="Lists, XML" saveAttachments="false" /> </Parse> <Parse emailAsList="false" useJustDomain="false" fromAddress="false" toAddress="true"> <EmailRule address="[email protected]" folder="Special Interest Groups|Northern Colorado Architects Group" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Support|SpamBayes" saveAttachments="false" /> </Parse> <Parse emailAsList="false" useJustDomain="false" fromAddress="true" toAddress="false"> <EmailRule address="[email protected]" folder="Support|GoDaddy" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Support|No-IP.com" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Discussions|Orchard Project" saveAttachments="false" /> </Parse> <Parse emailAsList="false" useJustDomain="true" fromAddress="true" toAddress="false"> <EmailRule address="@agilejournal.com" folder="Newsletters|Agile Journal" saveAttachments="false"/> <EmailRule address="@axosoft.ccsend.com" folder="Newsletters|Axosoft Newsletter" saveAttachments="false"/> <EmailRule address="@axosoft.com" folder="Newsletters|Axosoft Newsletter" saveAttachments="false"/> <EmailRule address="@cmcrossroads.com" folder="Newsletters|CM Crossroads" saveAttachments="false" /> <EmailRule address="@urbancode.com" folder="Newsletters|Urbancode" saveAttachments="false" /> <EmailRule address="@urbancode.ccsend.com" folder="Newsletters|Urbancode" saveAttachments="false" /> <EmailRule address="@Infragistics.com" folder="Newsletters|Infragistics" saveAttachments="false" /> <EmailRule address="@zdnet.online.com" folder="Newsletters|ZDNet Tech Update Today" saveAttachments="false" /> <EmailRule address="@sqlservercentral.com" folder="Newsletters|SQLServerCentral.com" saveAttachments="false" /> <EmailRule address="@simple-talk.com" folder="Newsletters|Simple-Talk Newsletter" saveAttachments="false" /> </Parse> </TargetPST> <TargetPST name="[Sharpen the Saw]"> <Parse emailAsList="false" useJustDomain="false" fromAddress="false" toAddress="true"> <EmailRule address="[email protected]" folder="Head Geek|Job Alerts" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Social|LinkedIn USMC" saveAttachments="false"/> </Parse> <Parse emailAsList="false" useJustDomain="false" fromAddress="true" toAddress="false"> <EmailRule address="[email protected]" folder="Head Geek|Job Alerts" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Head Geek|Job Alerts" saveAttachments="false" /> <EmailRule address="[email protected]" folder="Social|Cruise Critic" saveAttachments="false"/> </Parse> <Parse emailAsList="false" useJustDomain="true" fromAddress="true" toAddress="false"> <EmailRule address="@moody.edu" folder="Social|5 Love Languages" saveAttachments="false" /> <EmailRule address="@postmaster.twitter.com" folder="Social|Twitter" saveAttachments="false"/> <EmailRule address="@diabetes.org" folder="Physical|American Diabetes Association" saveAttachments="false"/> <EmailRule address="@membership.webshots.com" folder="Social|Webshots" saveAttachments="false"/> </Parse> </TargetPST> </EmailRuleList> Now, I have both an FromAddress and a ToAddress that is parsed from an incoming email. I would like to do a LINQ query against a class set that was deserialized from this XML. For instance: ToAddress = [email protected] FromAddress = [email protected] Query: Get EmailRule.Include(Parse).Include(TargetPST) where address == ToAddress AND Parse.ToAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [ToAddress Domain Only] AND Parse.ToAddress==true AND Parse.useJustDomain==true Get EmailRule.Include(Parse).Include(TargetPST) where address == FromAddress AND Parse.FromAddress==true AND Parse.useJustDomain==false Get EmailRule.Include(Parse).Include(TargetPST) where address == [FromAddress Domain Only] AND Parse.FromAddress==true AND Parse.useJustDomain==true I am having a hard time figuring this LINQ query out. I can, of course, loop on all the bits in the XML like so (includes deserialization into objects): XmlSerializer s = new XmlSerializer(typeof(EmailRuleList)); TextReader r = new StreamReader(path); _emailRuleList = (EmailRuleList)s.Deserialize(r); TargetPST[] PSTList = _emailRuleList.Items; foreach (TargetPST targetPST in PSTList) { olRoot = GetRootFolder(targetPST.name); if (olRoot != null) { Parse[] ParseList = targetPST.Items; foreach (Parse parseRules in ParseList) { EmailRule[] EmailRuleList = parseRules.Items; foreach (EmailRule targetFolders in EmailRuleList) { } } } } However, this means going through all these loops for each and every address. It makes more sense to me to query against the Objects. Any tips appreciated!

  • UISearchDisplayController "shouldReloadTableForSearchString return NO" reloads table

    Why does my UISearchDisplayController show "No results" even if the shouldReloadTableForSearchString method returns NO? Shouldn't it just do nothing and stay black?

  • Refactoring method with many conditional return statements

    - by MC.
    Hi, I have a method for validation that has many conditional statements. Basically it goes If Check1 = false return false If Check2 = false return false etc FxCop complains that the cyclomatic complexity is too high. I know that it is not best practice to have return statements in the middle of functions, but at the same time the only alternative I see is an ugly list of If-else statements. What is the best way to approach this? Thanks in advance.

  • MAC addresses on dual-NIC mainboards

    - by Tom O'Connor
    Here's a weird problem. We've got a number of devices with dual-NIC mainboards. Some are Realtek NICs, which suck. Some are Intel e1000s, which don't. I've just noticed on 2 machines, one is an Intel NIC, one is a Realtek, that when I put the MAC address of one machine into the dhcpd.conf file on our DHCP server to get it to PXE boot the machine into a rebuild environment, initially everything is fine. The server gets a DHCP allocation, and PXE boots into the Ubuntu preseed enviroment. On one or two machines, it gets as far as Ubuntu's DHCP network configuration, and fails. If i pull up a busybox shell (on tty2 on the installing machine), and run ip link, I can see that the UP flag is set on the other NIC. Here's some stuff. host xeon16-ghz240-gb48-node1 { hardware ethernet BC:AE:C5:07:1F:18; filename "pxelinux.0"; next-server 192.168.123.80; } That's what's in dhcpd.conf This is what ip link on the evil machine looks like. Only one NIC is actually connected (deliberately). As you can see, the NIC that's in the dhcpd config, is not marked as UP, and the link that is UP, isn't the one in DHCP. So far I've seen this on two brands of dual-NIC configuration. Does anyone know 1) what's causing it, and b) What we can do about it?

  • Adding Static IP's to the NIC

    - by Brett Powell
    We are currently working on migrating a lot of new machines to our network, and my job this morning was to setup all of the IP Addresses. I worked on this all morning, and when I got back tonight I was informed that they had all been setup incorrectly, and had to be removed and re-added. I am quite confused as I have been setting up IP's on machines for a long time and I am curious as to what the issue is. Just taking into account this example... 72.26.196.160/29 255.255.255.248 A /29 block is 5 usable IP's. With the script I wrote and used, the IP Addresses .162 - .166 were added to the NIC. I can't remember now what the name for .161 was, but isn't it the broadcast address or something which isn't assigned to the NIC when adding additional IP Blocks? I am curious as to where my logic is failing me. Not to mention even if .161 was to be added, there is no reason why all of the IPs would have to be removed, as .161 could just be added in addition to these.

  • Simple way to return anonymous types (to make MVC using LINQ possible)

    - by BlueRaja The Green Unicorn
    I'd like to implement MVC while using LINQ (specifically, LINQ-to-entities). The way I would do this is have the Controller generate (or call something which generates) the result-set using LINQ, then return that to the View to display the data. The problem is, if I do: return (from o in myTable select o); All the columns are read from the database, even the ones (potentially dozens) I don't want. And - more importantly - I can't do something like this: return (from o in myTable select new { o.column }); because there is no way to make anonymous types type-safe! I know for sure there is no nice, clean way of doing this in 3.5 (this is not clean...), but what about 4.0? Is there anything planned, or even proposed? Without something like duck-typing-for-LINQ, or type-safe anonymous return values (it seems to me the compiler should certainly be capable of that), it appears to be nearly impossible to cleanly separate the Controller from the View.

  • Marshal generic return types for com interop

Let's say I have the following class: [ComVisible(true)] public class Foo { public IEnumerable GetStr() // Generic return type { yield break; } } I know that IEnumerable implements IEnumerable. Can I force tlbexp.exe (via return: attribute or some other way) to expose GetStr() method as a method returning IEnumerbale?

  • When would ShowDialog() return null?

    - by Joe White
    WPF's Window.ShowDialog method returns a nullable boolean. So does CommonDialog.ShowDialog. Now, I understand cases where these would return false (user clicked Cancel or pressed Esc), and when they would return true (code sets Window.DialogResult to true, probably in response to OK being clicked). But null? My first thought is that clicking the title bar's Close button might return null. But the docs state (and I confirmed by testing) that the title-bar Close button is treated as a Cancel. So when would Window.ShowDialog or CommonDialog.ShowDialog ever return null?

  • Locate modules by stack address

    - by PaulH
    I have a Winodws Mobile 6.1 application running on an ARMV4I processor. Given a stack address (from unwinding an exception), I like to determine what module owns that address. Using the ToolHelpAPI, I'm able to determine most modules using the following method: HANDLE snapshot = ::CreateToolhelp32Snapshot( TH32CS_SNAPMODULE | TH32CS_GETALLMODS, 0 ); if( INVALID_HANDLE_VALUE != snapshot ) { MODULEENTRY32 mod = { 0 }; mod.dwSize = sizeof( mod ); if( ::Module32First( snapshot, &mod ) ) { do { if( stack_address > (DWORD)mod.modBaseAddr && stack_address < (DWORD)( mod.modBaseAddr + mod.modBaseSize ) ) { // Found the module! // offset = stack_address - mod.modBaseAddr break; } } while( ::Module32Next( snapshot, &mod ) ); } ::CloseToolhelp32Snapshot( snapshot ); } But, I don't always seem to be able to find a module that matches an address. For example: stack address module offset 0x03f65bd8 coredll.dll + 0x0001bbd8 0x785cab1c mylib.dll + 0x0002ab1c 0x785ca9e8 mylib.dll + 0x0002a9e8 0x785ca0a0 mylib.dll + 0x0002a0a0 0x785c8144 mylib.dll + 0x00028144 0x3001d95c ??? 0x3001dd44 ??? 0x3001db90 ??? 0x03f88030 coredll.dll + 0x0003e030 0x03f8e46c coredll.dll + 0x0004446c 0x801087c4 ??? 0x801367b4 ??? 0x8010ce78 ??? 0x801086dc ??? 0x03f8e588 coredll.dll + 0x00044588 0x785a56a4 mylib.dll + 0x000056a4 0x785bdd60 mylib.dll + 0x0001dd60 0x785bbd0c mylib.dll + 0x0001bd0c 0x785bdb38 mylib.dll + 0x0001db38 0x3001db20 ??? 0x3001dc40 ??? 0x3001a8a4 ??? 0x3001a79c ??? 0x03f67348 coredll.dll + 0x0001d348 Where do I find those stack addresses that are missing? Any suggestions? Thanks, PaulH

  • Correct method to search for AD user by email address from .NET

    - by BrianLy
    I'm having some issues with code that is intended to find a user in Active Directory by searching on their email address. I have tried 2 methods but I'm sometimes finding that the FindOne() method will not return any results on some occasions. If I look up the user in the GAL in Outlook I see the SMTP email address listed. My end goal is to confirm that the user exists in AD. I only have the email address as search criteria, so no way to use first or last name. Method 1: Using mail property: DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(mail=" + email + ")"; search.PropertiesToLoad.Add("mail"); SearchResult result = search.FindOne(); Method 2: proxyAddresses property: DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(proxyAddresses=SMTP:" + email + ")"; // I've also tried with =smtp: search.PropertiesToLoad.Add("mail"); SearchResult result = search.FindOne(); I've tried changing the case of the email address input but it still does not return a result. Is there a problem here with case sensitivity? If so, what is the best way to resolve it?
