  • What is the right way to modify a wordpress query in a plugin?

    - by starepod
    Basically i am playing with a plugin that allows future-dated posts on archive pages. My question is broader than this specific functionality, but everyone likes some context. I have my head around many of the plugin development concepts, but must be missing something very basic. I can successfully rewrite a query that gives me the results i want like this: function modify_where( $where ) { global $wp_query; // define $year, $cat, etc if( is_archive() ) { $where = " AND YEAR(wp_posts.post_date)='".$year."' AND wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN ('".$cat."') AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'future')"; } return $where; } add_filter('posts_where', 'catCal_where' ); However, if i attempt to create a new WP_Query('different_query_stuff') after the main loop the new query uses the same WHERE statement outlined above. The question is : What am I missing? Thanks.

  • Codeigniter: how do I select count when `$query->num_rows()` doesn't work for me?

    - by mOrloff
    I have a query which is returning a sum, so naturally it returns one row. I need to count the number of records in the DB which made that sum. Here's a sample of the type of query I am talking about (MySQL): SELECT i.id, i.vendor_quote_id, i.product_id_requested, SUM(i.quantity_on_hand) AS qty, COUNT(i.quantity_on_hand) AS count FROM vendor_quote_item AS i JOIN vendor_quote_container AS c ON i.vendor_quote_id = c.id LEFT JOIN company_types ON company_types.company_id = c.company_id WHERE company_types.company_type = 'f' AND i.product_id_requested = 12345678 I have found and am now using the select_min(), select_max(), and select_sum() functions, but my COUNT() is still hard-coded in. The main problem is that I am having to specify the table name in a tightly coupled manner with something like $this->$db->select( 'COUNT(myDbPrefix_vendor_quote_item.quantity_on_hand) AS count' ) which kills portability and makes switching environments a PIA. How can/should I get my the count values I am after with CI in an uncoupled way??

  • Using jQuery and SPServices to Display List Items

    - by Bil Simser
    I had an interesting challenge recently that I turned to Marc Anderson’s wonderful SPServices project for. If you haven’t already seen or used SPServices, please do. It’s a jQuery library that does primarily two things. First, it wraps up all of the SharePoint web services in a nice little AJAX wrapper for use in JavaScript. Second, it enhances the form editing of items in SharePoint so you’re not hacking up your List Form pages. My challenge was simple but interesting. The user wanted to display a SharePoint item page (DispForm.aspx, which already had some customization on it to display related items via this blog post from Codeless Solutions for SharePoint) but launch from an external application using the value of one of the fields in the SharePoint list. For simplicity let’s say my list is a list of customers and the related list is a list of orders for that customer. It would look something like this (click on the item to see the full image): Your first thought might be, that’s easy! Display the customer information using a DataView Web Part and filter the item using a query string to match the customer number. However there are a few problems with this idea: You’ll need to build a custom page and then attach that related orders view to it. This is a bit of a problem because the solution from Codeless Solutions relies on the Title field on the page to be displayed. On a custom page you would have to recreate all of the elements found on the DispForm.aspx page so the related view would work. The DataView Web Part doesn’t look *exactly* like what the out of the box display form page does. Not a huge problem and can be overcome with some CSS style overrides but still, more work. A DVWP showing a single record doesn’t have the same toolbar that you would using the DispForm.aspx. Not a show-stopper and you can rebuild the toolbar but it’s going to potentially require code and then there’s the security trimming, etc. that you have to get right. DVWPs are not automatically updated if you add a column to the list like DispForm.aspx is. Work, work, work. For these reasons I thought it would be easier to take the already existing (modified) DispForm.aspx page and just add some jQuery magic to the page to find the item. Why do we need to find it? DispForm.aspx relies on a querystring parameter called “ID” which then displays whatever that item ID number is in the list. Trouble is, when you’re coming in from an external app via a link, you don’t know what that internal ID is (and frankly shouldn’t). I don’t like exposing internal SharePoint IDs to the outside world for the same reason I don’t do it with database IDs. They’re internal and while it’s find to use on the site itself you don’t want external links using it. It’s volatile and can change (delete one item then re-add it back with the same data and watch any ID references break). The next thought might be to call a SharePoint web service with a CAML query to get the item ID number using some criteria (in this case, the customer number). That’s great if you have that ability but again we had an existing application we were just adding a link to. The last thing I wanted to do was to crack open the code on that sucker and start calling web services (primarily because it’s Java, but really I’m a lazy geek). However if you’re doing this and have access to call a web service that would be an option. Back to this problem, how do I a) find a SharePoint List Item based on some field value other than ID and b) make it low impact so I can just construct a URL to it? That’s where jQuery and SPServices came to the rescue. After spending a few hours of emails back and forth with Marc and a couple of phone calls (and updating jQuery to the latest version, duh!) it was a simple answer. First we need a reference to a) jQuery b) SPServices and c) our script. I just dropped a Content Editor Web Part, the Swiss Army Knives of Web Parts, onto the DispForm.aspx page and added these lines: <script type="text/javascript" src="http://intranet/JavaScript/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="http://intranet/JavaScript/jquery.SPServices-0.5.3.min.js"></script> <script type="text/javascript" src="http://intranet/JavaScript/RedirectToID.js"> </script> Update it to point to where you keep your scripts located. I prefer to keep them all in Document Libraries as I can make changes to them without having to remote into the server (and on a multiple web front end, that’s just a PITA), it provides me with version control of sorts, and it’s quick to add new plugins and scripts. Now we can look at our RedirectToID.js script. This invokes the SPServices Library to call the GetListItems method of the Lists web service and then rewrites the URL to DispForm.aspx to use the correct SharePoint ID (the internal one). $(document).ready(function(){ var queryStringValues = $().SPServices.SPGetQueryString(); var id = queryStringValues["ID"]; if(id == "0") { var customer = queryStringValues["CustomerNumber"]; var query = "<Query><Where><Eq><FieldRef Name='CustomerNumber'/><Value Type='Text'>" + customer + "</Value></Eq></Where></Query>"; var url = window.location; $().SPServices({ operation: "GetListItems", listName: "Customers", async: false, CAMLQuery: query, completefunc: function (xData, Status) { $(xData.responseXML).find("[nodeName=z:row]").each(function(){ id = $(this).attr("ows_ID"); url = $().SPServices.SPGetCurrentSite() + "/Lists/Customers/DispForm.aspx?ID=" + id; window.location = url; }); } }); } }); What’s happening here? Line 3: We call SPServices.SPGetQueryString to get an array of query string values (a handy function in the library as I had 15 lines of code to do this which is now gone). Line 4: Extract the ID value from the query string Line 6: If we pass in “0” it means we’re looking up a field value. This allows DispForm.aspx to work like normal with SharePoint lists but lookup our values when invoked. Why ID at all? DispForm.aspx doesn’t work unless you pass in something and “0” is a *magic* number that will invoke the page but not lookup a value in the database. Line 8-15: Extract the CustomerNumber query string value, build a CAML query to find it then call the GetListitems method using SPServices Line 16: Process the results in our completefunc to iterate over all the rows (there should only be one) and extract the real ID of the item Line 17-20: Build a new URL based on the site (using a call to SPGetCurrentSite) and append our real ID to redirect to the DispForm.aspx page As you can see, it dynamically creates a CAML query for the call to the web service using the passed in value. You could even make this generic to take in different query strings, one for the field name to search for and the other for the value to find. That way it could be used for any field you want. For example you could bring up the correct item on the DispForm.aspx page based on customer name with something like this: http://myserver/Lists/Customers/DispForm.aspx?ID=0&FilterId=CustomerName&FilterValue=Sony Use your imagination. Some people would opt for building a custom page with a DVWP but if you want to leverage all the functionality of DispForm.aspx this might come in handy if you don’t want to rely on internal SharePoint IDs.

  • Dynamic Paging and Sorting

    - by Ricardo Peres
    Since .NET 3.5 brought us LINQ and expressions, I became a great fan of these technologies. There are times, however, when strong typing cannot be used - for example, when you are developing an ObjectDataSource and you need to do paging having just a column name, a page index and a page size, so I set out to fix this. Yes, I know about Dynamic LINQ, and even talked on it previously, but there's no need to add this extra assembly. So, without further delay, here's the code, in both generic and non-generic versions: public static IList ApplyPagingAndSorting(IEnumerable enumerable, Type elementType, Int32 pageSize, Int32 pageIndex, params String [] orderByColumns) { MethodInfo asQueryableMethod = typeof(Queryable).GetMethods(BindingFlags.Static | BindingFlags.Public).Where(m = (m.Name == "AsQueryable") && (m.ContainsGenericParameters == false)).Single(); IQueryable query = (enumerable is IQueryable) ? (enumerable as IQueryable) : asQueryableMethod.Invoke(null, new Object [] { enumerable }) as IQueryable; if ((orderByColumns != null) && (orderByColumns.Length 0)) { PropertyInfo orderByProperty = elementType.GetProperty(orderByColumns [ 0 ]); MemberExpression member = Expression.MakeMemberAccess(Expression.Parameter(elementType, "n"), orderByProperty); LambdaExpression orderBy = Expression.Lambda(member, member.Expression as ParameterExpression); MethodInfo orderByMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "OrderBy").ToArray() [ 0 ].MakeGenericMethod(elementType, orderByProperty.PropertyType); query = orderByMethod.Invoke(null, new Object [] { query, orderBy }) as IQueryable; if (orderByColumns.Length 1) { MethodInfo thenByMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "ThenBy").ToArray() [ 0 ].MakeGenericMethod(elementType, orderByProperty.PropertyType); PropertyInfo thenByProperty = null; MemberExpression thenByMember = null; LambdaExpression thenBy = null; for (Int32 i = 1; i 0) { MethodInfo takeMethod = typeof(Queryable).GetMethod("Take", BindingFlags.Public | BindingFlags.Static).MakeGenericMethod(elementType); MethodInfo skipMethod = typeof(Queryable).GetMethod("Skip", BindingFlags.Public | BindingFlags.Static).MakeGenericMethod(elementType); query = skipMethod.Invoke(null, new Object [] { query, pageSize * pageIndex }) as IQueryable; query = takeMethod.Invoke(null, new Object [] { query, pageSize }) as IQueryable; } MethodInfo toListMethod = typeof(Enumerable).GetMethod("ToList", BindingFlags.Static | BindingFlags.Public).MakeGenericMethod(elementType); IList list = toListMethod.Invoke(null, new Object [] { query }) as IList; return (list); } public static List ApplyPagingAndSorting(IEnumerable enumerable, Int32 pageSize, Int32 pageIndex, params String [] orderByColumns) { return (ApplyPagingAndSorting(enumerable, typeof(T), pageSize, pageIndex, orderByColumns) as List); } List list = new List { new DateTime(2010, 1, 1), new DateTime(1999, 1, 12), new DateTime(1900, 10, 10), new DateTime(1900, 2, 20), new DateTime(2012, 5, 5), new DateTime(2012, 1, 20) }; List sortedList = ApplyPagingAndSorting(list, 3, 0, "Year", "Month", "Day"); SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

  • Finding a person in the forest

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved finding a person in the forest or Limiting the AD result in SharePoint People Picker There are times when we need to limit the SharePoint audience of certain farms or servers or site collections to a particular audience. One of my experiences involved limiting access to US citizens, another to a particular location. Now, most of us – your humble servant included – are not Active Directory experts – but we must be able to handle the “audience restrictions” as required. So here is how it’s done in a nutshell. Important note. Not all could be done in PowerShell (at least not yet)! There are no Windows PowerShell commands to configure People Picker. The stsadm command is: stsadm -o setproperty -pn peoplepicker-searchadcustomquery -pv ADQuery –url http://somethingOrOther Note the long-hyphenated property name. Now to filling the ADQuery.   LDAP Query in a nutshell Syntax LDAP is no older than SQL and an LDAP query is actually a query against the LDAP Database. LDAP attributes are the equivalent of Database columns, so why do we have to learn a new query language? Beats me! But we must, so here it is. The syntax of an LDAP query string is made of individual statements with relational operators including: = Equal <= Lower than or equal >= Greater than or equal… and memberOf – a group membership. ! Not * Wildcard Equal and memberOf are the most commonly used. Checking for absence uses the ! – not and the * - wildcard Example: (SN=Grant) All whose last name – SurName – is Grant Example: (!(SN=Grant)) All except Grant Example: (!(SN=*)) all where there is no SurName i.e SurName is absent (probably Rappers). Example: (CN=MyGroup) Common Name is MyGroup.  Example: (GN=J*) all the Given Names that start with J (JJ, Jane, Jon, John, etc.) The cryptic SN, CN, GN, etc. are attributes and more about them later All the queries are enclosed in parentheses (Query). Complex queries are comprised of sets that are in AND or OR conditions. AND is denoted by the ampersand (&) and the OR is denoted by the vertical pipe (|). The general syntax is that of the Prefix polish notation where the operand precedes the variables. E.g +ab is the sum of a and b. In an LDAP query (&(A)(B)) will garner the objects for which both A and B are true. In an LDAP query (&(A)(B)(C)) will garner the objects for which A, B and C are true. There’s no limit to the number of conditions. In an LDAP query (|(A)(B)) will garner the objects for which either A or B are true. In an LDAP query (|(A)(B)(C)) will garner the objects for which at least one of A, B and C is true. There’s no limit to the number of conditions. More complex queries have both types of conditions and the parentheses determine the order of operations. Attributes Now let’s get into the SN, CN, GN, and other attributes of the query SN – is the SurName (last name) GN – is the Given Name (first name) CN – is the Common Name, usually GN followed by SN OU – is an Organization Unit such as division, department etc. DC – is a Domain Content in the AD forest l – lower case ‘L’ stands for location. Jerusalem anybody? Or Katmandu. UPN – User Principal Name, is usually the first part of an email address. By nature it is unique in the forest. Most systems set the UPN to be the first initial followed by the SN of the person involved. Some limit the total to 8 characters. If we have many ‘jsmith’ we have to somehow distinguish them from each other. DN – is the distinguished name – a name unique to AD forest in which it lives. Usually it’s a CN with some domain or group distinguishers. DN is important in conjunction with the memberOf relation. Groups have stricter requirement. Each group has to have a unique name - its CN and it has to be unique regardless of its place. See more below. All of the attributes are case insensitive. CN, cn, Cn, and cN are identical. objectCategory is an element that requires special consideration. AD contains many different object like computers, printers, and of course people and groups. In the queries below, we’re limiting our search to people (person). Putting it altogether Let’s get a list of all the Johns in the SPAdmin group of the Jerusalem that local domain. (&(objectCategory=person)(memberOf=cn=SPAdmin,ou=Jerusalem,dc=local)) The memberOf=cn=SPAdmin uses the cn (Common Name) of the SPAdmin group. This is how the memberOf relation is used. ‘SPAdmin’ is actually the DN of the group. Also the memberOf relation does not allow wild cards (*) in the group name. Also, you are limited to at most one ‘OU’ entry. Let’s add Marvin Minsky to the search above. |(&(objectCategory=person)(memberOf=cn=SPAdmin,ou=Jerusalem,dc=local))(CN=Marvin Minsky) Here I added the or pipeline at the beginning of the query and put the CN requirement for Minsky at the end. Note that if Marvin was already in the prior result, he’s not going to be listed twice. One last note: You may see a dryer but more complete list of attributes rules and examples in: http://www.tek-tips.com/faqs.cfm?fid=5667 And finally (thus negating the claim that my previous note was last), to the best of my knowledge there are 3 more ways to limit the audience. One is to use the peoplepicker-searchadcustomfilter property using the same ADQuery. This works only in SP1 and above. The second is to limit the search to users within this particular site collection – the property name is peoplepicker-onlysearchwithinsitecollection and the value is yes (-pv yes) And the third is –pn peoplepicker-serviceaccountdirectorypaths –pv “OU=ou1,DC=dc1…..” Again you are limited to at most one ‘OU’ phrase – no OU=ou1,OU=ou2… And now the real end. The main property discussed in this sprawling and seemingly endless monogram – peoplepicker-searchadcustomquery - is the most general way of getting the job done. Here are a few examples of command lines that worked and some that didn’t. Can you see why?

  • OData Mix10 &ndash; Part Dos

    - by Jon Dalberg
    The other day I had a snazzy post on fetching all the video (WMV) files from Mix ‘10. A simple, console application that grabbed the urls from the OData feed and downloaded the videos. I wanted to change that app to fire the OData query asynchronously so here’s what resulted: 1: static void Main(string[] args) 2: { 3: var mix = new Mix.EventEntities(new Uri("http://api.visitmix.com/OData.svc")); 4:   5: var temp = mix.Files.Where(f => f.TypeName == "WMV"); 6: var query = temp as DataServiceQuery<Mix.File>; 7:   8: query.BeginExecute(OnFileQueryComplete, query); 9:   10: // waiting... 11: Console.ReadLine(); 12: } 13:   14: static void OnFileQueryComplete(IAsyncResult result) 15: { 16: var query = result.AsyncState as DataServiceQuery<Mix.File>; 17: var response = query.EndExecute(result); 18:   19: var web = new WebClient(); 20:   21: var myVideos = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyVideos), "Mix10"); 22:   23: Directory.CreateDirectory(myVideos); 24:   25: foreach (Mix.File f in response) 26: { 27: var fileName = new Uri(f.Url).Segments.Last(); 28: Console.WriteLine(f.Url); 29: web.DownloadFile(f.Url, Path.Combine(myVideos, fileName)); 30: } 31: } There are two important things here that are not explained well in the MSDN docs: See lines 5 and 6? That’s where I query for the WMV files and it returns an IQueryable<T>. You *have* to cast that to a DataServiceQuery<T> and then call BeginExecute. The documented example does not filter so it didn’t show that step. Line 16 shows the correct way to get the previously executed DataServiceQuery<T> from the async result. If you looked at the MSDN example docs it shows (incorrectly) just casting the result, like this: // wrong var query = result as DataServiceQuery<Mix.File>; Other than those items it is relatively straight forward and we’re all async-ified. Enjoy!

  • Strengthening code with possibly useless exception handling

    - by rdurand
    Is it a good practice to implement useless exception handling, just in case another part of the code is not coded correctly? Basic example A simple one, so I don't loose everybody :). Let's say I'm writing an app that will display a person's information (name, address, etc.), the data being extracted from a database. Let's say I'm the one coding the UI part, and someone else is writing the DB query code. Now imagine that the specifications of your app say that if the person's information is incomplete (let's say, the name is missing in the database), the person coding the query should handle this by returning "NA" for the missing field. What if the query is poorly coded and doesn't handle this case? What if the guy who wrote the query handles you an incomplete result, and when you try to display the informations, everything crashes, because your code isn't prepared to display empty stuff? This example is very basic. I believe most of you will say "it's not your problem, you're not responsible for this crash". But, it's still your part of the code which is crashing. Another example Let's say now I'm the one writing the query. The specifications don't say the same as above, but that the guy writing the "insert" query should make sure all the fields are complete when adding a person to the database to avoid inserting incomplete information. Should I protect my "select" query to make sure I give the UI guy complete informations? The questions What if the specifications don't explicitly say "this guy is the one in charge of handling this situation"? What if a third person implements another query (similar to the first one, but on another DB) and uses your UI code to display it, but doesn't handle this case in his code? Should I do what's necessary to prevent a possible crash, even if I'm not the one supposed to handle the bad case? I'm not looking for an answer like "(s)he's the one responsible for the crash", as I'm not solving a conflict here, I'd like to know, should I protect my code against situations it's not my responsibility to handle? Here, a simple "if empty do something" would suffice. In general, this question tackles redundant exception handling. I'm asking it because when I work alone on a project, I may code 2-3 times a similar exception handling in successive functions, "just in case" I did something wrong and let a bad case come through.

  • BizTalk 2009 - Messages: Last 100 Received

    - by StuartBrierley
    Having previously talked about the lack of the traditional HAT in BizTalk 2009, the question then becomes how do you replicate some of the functionality that was previsouly relied on? In BizTalk 2004 we had a query in HAT to return the messages received in the last day.  While not a direct replacement the following query replicates some of the usefullness of this query in a BizTalk 2009 hatless environment. Basically we are creating a query to search for the last one hundred tracked messages that were received by BizTalk: Coming up: Messages - last 100 sent Messages - last 50 suspended Service instances - last 100

  • MySQL-5.5.10 - Lost connection to MySQL server during query (Both Web Clients and MySQL Slaves)

    - by kwiksand
    We've just upgraded our existing MySQL5.1 DB servers to newer (much better) hardware with MySQL 5.5, and things have been going mostly smoothly for almost 6 weeks. Just the last few days, I've noticed a few errors, such as: From a MySQL Slave: [ERROR] Error reading packet from server: Lost connection to MySQL server during query ( server_errno=2013) Or From Apache/Other: Lost connection to MySQL server at 'reading initial communication packet', system error: 110 At one point this evening, many webnodes reported this error for a three minute period (many such reports as this was in a busy period). However, the issues don't appear to correspond with any times of extreme load. For all intents and purposes, the connection/thread load on MySQL is at a normal rate (between about 10 and 40 connected threads), and Web load has been a LOT higher at times over the last few weeks. Could there bee other reasons for these connection errors, that I'm not seeing?

  • How to disable proxy cache when query string is empty?

    - by chx
    With nginx I have server { listen 1.2.3.4:80 proxy_cache_valid 200 302 5m; location / { try_files $uri @upstream; root $root; } } When I go http://example.com/foobar it generates a redirect to http://example.com/foobar?filter_distance=50&... which is visitor dependent so I would like to not cache this redirect. I need to bypass cache when the query string is empty. I am a bit lost because location /foobar will match both.

  • Can an LDAP query on AD provide the netbios domain name for a single account when using the Global Catalog?

    - by Kirk Liemohn
    I am using ADSI Edit to look at LDAP properties of a single user account in AD. I see properties such as userPrincipalName, but I do not see one for the fully qualified domain name (FQDN) or the netbios domain name. We will be setting up the Global Catalog (GC) to give us LDAP access to multiple domains and through configuration in an application we map LDAP properties to user profile properties within the application. With typical AD the FQDN and netbios domain name are the same for all users, but with the GC involved we need this additional information. We really only need the netbios domain name (the FQDN is not good enough). Maybe there is a LDAP query that can be done to request this information from a more top-level object in AD?

  • How do we increase the maximum allowed HTTP GET query length in Jetty?

    - by Mike
    We are using Jetty to run an Apache Solr index. We've had some queries that have grown way beyond the previously expected maximum length, and are now having issues wehre most queries are not returning any data because the URL gets truncated. These requests are not being made through a browser, they're being made programmatically using the Apache_Solr_Service PHP library. The application is expecting queries to come in as HTTP GET requests, so simply switching to a POST will not solve this problem. How can we increase the maximum allowed HTTP GET query length in Jetty? Thanks!

  • How do I run a search query based on recipient in PowerShell for Exchange 2010?

    - by LucidLuniz
    I've tried to run the following commands but neither work and I'm not sure how I should setup the query. I tried to find a full list of available search strings but couldn't locate one online or using help. I did find the list here (http://technet.microsoft.com/en-us/library/bb232132.aspx#AQS) but it doesn't include the search queries I am looking for (based on the fact that it doesn't even list "Received:" which I know is an option because I use it all the time. Search-Mailbox -Identity -SearchQuery 'Received:' 'To:' -LogLevel Full –DeleteContent Search-Mailbox -Identity -SearchQuery 'Received:' 'Recipient:' -LogLevel Full –DeleteContent Thanks in advance!

  • Get other ldap query strings associated with a domain.

    - by seekerOfKnowledge
    I have in Softerra LDAP Administration something like the following: server: blah.gov OU=Domain Controllers etc... ldap://subdomain.blah.gov I can't figure out how to, in C#, get those other ldap subdomain query strings. I'm not sure how else to explain it, so ask questions and I'll try to clarify. Updated: This is what Softerra LDAP Administrator looks like. The ldap queries near the bottom are not children of the above node, but somehow, the program knows about them and linked them in the GUI. If I could figure out how, that would fix my problem.

  • Ubuntu 10.04 not detecting multiple monitors

  • apcupsd on Linux does not report on APC BackUPS Pro 900

    - by lserni
    From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64). The USB port is detected, lsusb reports Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply and lsusb -v -s002:003 confirms and expands: Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x051d American Power Conversion idProduct 0x0002 Uninterruptible Power Supply bcdDevice 0.90 iManufacturer 1 American Power Conversion iProduct 2 Back-UPS RS 900G FW:879.L4 .I USB FW:L4 bNumConfigurations 1 Configuration Descriptor: [...] Interface Descriptor: [...] bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 33 US bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 1134 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 100 Device Status: 0x0000 (Bus Powered) The kernel recognizes this and duly sets up crw------- 1 root root 180, 96 Nov 4 16:11 /dev/usb/hiddev0 As far as I know, everything is as it should be. I have put the standard configuration in /etc/apcupsd/apcupsd.conf (which is Unix-terminated, ASCII-only, no BOM (just in case)) UPSCABLE usb UPSTYPE usb DEVICE (I have also tried commenting out DEVICE, and setting a device of /dev/puppa results in an access attempt to /dev/puppa, not some /var/lib/dev/puppa or /dev/puppa\r\n). Yet, what apcaccess tells me is VERSION : 3.14.10 (13 September 2011) suse CABLE : USB Cable DRIVER : USB UPS Driver UPSMODE : Stand Alone STARTTIME: 2013-11-04 16:24:22 +0100 MODEL : STATUS : NOBATT LINEV : 000.0 Volts LOADPCT : 0.0 Percent Load Capacity BCHARGE : 000.0 Percent TIMELEFT : 0.0 Minutes MBATTCHG : 5 Percent MINTIMEL : 3 Minutes MAXTIME : 0 Seconds SENSE : Low LOTRANS : 000.0 Volts HITRANS : 000.0 Volts It doesn't recognize the model, and reports no battery (and no voltage). This confirms that it's not the Microlink problem, or it would report the battery status, if precious little else. If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

  • Well....a ghost lives in my server...

    - by tsgiannis
    Hello to every body and greetings from Greece I have a rather unusual situation and i am running out of ideas. I have this old server (IBM x205 - P4 2.4Ghz,3xSCSI 36gb) and i was about a year ago i decided to use it as an additional domain controller,fax & file server...for this task i had a Delock 70154 SATA card along with 2x320 SATA II HDDs Everything was going super smoothly until about 3 weeks ago. I was on a trip and i was informermed when i got back that the server was found frozen...well i considered it was a glitch since a simple powerdown power up fixed everything.Again 2 weeks ago another freeze situation....it got suspicious but again power down power up everything was running.... Last again it frozen and when i power it up it came with a message that the Domain services could not start due to NTDS corruption....booting in safe mode revealed that there was an issue with the SATA Raid (degraded). After a lot of searching i degraded the server...cleaned Active Directory and pulled both HDDs out (one of these was really BAD ) and recovered my files (i had some problems with ho Delock handles the redudant HDD). Right now my server is vanilla simple...with only what the factory installed and here is where the fun begins. Everyday when i arrive at the office i find this particular machine dead..and i mean total dead...just a black screen and nothing else...the cpu fan is working ,the psu is working .keyboard and mouse are dead(they also lock my kvm) ...network is dead.... the machine is DEAD. I power it down forcilly ...i power it up and for the 8 hours i am in the office it works,either idling or running some kind of diagnostic...when i leave the office after some time..it maybe half an hour ...it maybe 4 hours the machine dies...at least this is the information the event log shows (" the previous shutdown at xx:xx:xx was unexpected) Well i must admit i am runnig out of ideas.... I have tried Memtest....nothing Passmark burn in test.....nothing Carefull study of the event log.....nothing Set Instead of restart..BSOD....nothing Power sceheme to sleep...all set to never. i know there are a lot of other tools that heavily stress a machine like occt but .... the machine is old...today i will give them a try nevertheless ..... One idea is to reformat it...but ... i really like to find what is causing this because i could get to a situation that everything is working for a while and kaboom...one day again is dying.. I really need a helping hand and every opinion / idea is well welcomed.... iknow the obvious solution is to never leave the office but....i have a life...sory server...:) P.S this situation with the machine dying some time after is going on for about one week...everyday i would set either the RAID to rebuild....or to copy/recover files and while everythig was working

  • Cannot access boot menu with compaq 8510p

    - by pinouchon
    I have a problem with my HP compaq 8510p laptop: when I start it, the fan starts and the power light is on, but the screen displays nothing. When I insert a bootable hard drive, it activates the hard drive light (meaning that the CD is recognized) but it stops after a few seconds. Same thing with any hard drive: the drive is recognized but does not boot. What I've tried so far: Changing the hard drive or booting with no hard drive (same problem) Plugging anoher display via VGA : no display on the other screen Inserting a windows-7 CD (same problem) Booting only on battery, with battery and power cable, only with power cable (same problem) So it looks like something is preventing the laptop from booting and displaying the boot menu. Do you have experienced something similar with a laptop ? What could be wrong ? The laptop is out of warranty. The system used to be windows-7 x64. Edit: I went to the help desk of my university. A guy took a look (he also tried to plug an external screen) and said that the computer is dead: on the HP laptops eventually the GPU card dies and so does the motherboard because they are linked. He saw this many times, and even if I can fix the problem, the laptop would crash again after a while. Do you have similar experience with HP laptops ? (mine is 4 years old) Edit 2: Believe it or not, my laptop is magically working again. I have no clue about what is going on. Now it is like starting and old car: when you turn it on you secretly hope it will actually start... With that said, I expect my laptop to break again in the near future (its an HP after all) and I will accept an answer or add my own accordingly. Edit 3: As expected, the laptop is down again. This time, sometimes when I power it up, it shuts down automatically after 3 seconds, sometimes not at all. In addition, when it does not shut down on its own, the power button does not work : the only way to shut it down is by unplugging the battery. As before, the screen is black, and only the power and battery lights are on. (the other ones: hard drive and wifi are off). I have tried to plug in another power plug, removing the battery and removing the hard drive without success. I might buy another laptop. I've brought the laptop to a repair shop. The problem is indeed that the graphic card is down. It will be replaced by a new one.
