• getting service from wsdd via xpath not wroking (xmltask)

  - by subes

  Hi, I am trying to get the XPath "/deployment/service". Tested on this site: http://www.xmlme.com/XpathTool.aspx <?xml version="1.0" encoding="UTF-8" standalone="no"?> <deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org /axis/wsdd/providers/java"> <service name="kontowebservice" provider="java:RPC" style="rpc" use="literal"> <parameter name="wsdlTargetNamespace" value="http://strategies.spine"/> <parameter name="wsdlServiceElement" value="ExposerService"/> <parameter name="wsdlServicePort" value="kontowebservice"/> <parameter name="className" value="dmd4biz.container.webservice.konto.internal.KontoWebServiceImpl_WS"/> <parameter name="wsdlPortType" value="Exposer"/> <parameter name="typeMappingVersion" value="1.2"/> <operation xmlns:operNS="http://strategies.spine" xmlns:rtns="http://www.w3.org/2001/XMLSchema" name="expose" qname="operNS:expose" returnQName="exposeReturn" returnType="rtns:anyType" soapAction=""> <parameter xmlns:tns="http://www.w3.org/2001/XMLSchema" qname="in0" type="tns:anyType"/> </operation> <parameter name="allowedMethods" value="expose"/> <parameter name="scope" value="Request"/> </service> </deployment> I absolutely can't find out why it always tells me that my xpath does not match... This may be stupid, but am I missing something? EDIT Thanks to the answer from Dimitre Novatchev I was able to find a workaround: <xmltask failwithoutmatch="true" report="false"> <fileset dir="${src.gen}/" includes="**/*-deploy.wsdd" /> <copy path="//*[local-name()='service']" buffer="tmpServiceBuf" append="true" /> </xmltask> <xmltask failwithoutmatch="true" report="false" source="${basedir}/env/axis/WEB-INF/server-config.wsdd" dest="${build.stage}/resources/WEB-INF/server-config.wsdd"> <insert path="//*[local-name()='transport'][last()]" buffer="tmpServiceBuf" position="after" /> </xmltask> Binding namespaces with xmltask (which is the tool that gave me the headaches) seems not to be possible. The code above did the trick.

• ASP.NET MVC 3 NOT showing appropriate view, action called using jquery

  - by TunAntun

  I have a small problem. My action is : public ViewResult SearchForRooms(int HotelDDL) { List<Room> roomsInHotel = bl.ReturnRoomsPerHotel(HotelDDL); return View(roomsInHotel); } Here is the jquery that is calling the action: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#HotelDDL").change(function () { var text = $("#HotelDDL option:selected").text(); var value = $("#HotelDDL option:selected").val(); alert("Selected text=" + text + " Selected value= " + value); $.post("/Home/SearchForRooms", { HotelDDL: $("#HotelDDL option:selected").val() }); }); }); </script> And finally, here is the View that should be called: @model IEnumerable<RoomReservation.Entities.Entities.Room> @{ ViewBag.Title = "Search"; } <h2>Result</h2> <table> <tr> <th> City </th> <th> Hotel </th> <th> Room label </th> <th> Number of beds </th> <th> Price per night </th> <th></th> </tr> @foreach (var item in Model) { <tr> <td> @Html.DisplayFor(modelitem=>item.Hotel.City.Name) </td> <td> @Html.DisplayFor(modelItem => item.Hotel.Name) </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> <td> @Html.DisplayFor(modelItem => item.NumberOfBeds) </td> <td> @Html.DisplayFor(modelItem => item.PricePerNight) </td> </tr> } </table> Everthing is working ok (databse return all rooms correctly) except final view rendering. I have tried Phil's tool but it doesn't give me any suspicious hints: RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); So, why is it not showing after jscript send it's post method to SearchForRooms()? Thank you P.S. If you need any other piece of code please just say so.

• NSString cannot be released

  - by Stanley

  Consider the following method and the caller code block. The method analyses a NSString and extracts a "http://" string which it passes out by reference as an auto release object. Without releasing g_scan_result, the program works as expected. But according to non-arc rules, g_scan_result should be released since a retain has been called against it. My question are : Why g_scan_result cannot be released ? Is there anything wrong the way g_scan_result is handled in the posted coding below ? Is it safe not to release g_scan_result as long as the program runs correctly and the XCode Memory Leak tool does not show leakage ? Which XCode profile tools should I look into to check and under which subtitle ? Hope somebody knowledgeable could help. - (long) analyse_scan_result :(NSString *)scan_result target_url :(NSString **)targ_url { NSLog (@" RES analyse string : %@", scan_result); NSRange range = [scan_result rangeOfString:@"http://" options:NSCaseInsensitiveSearch]; if (range.location == NSNotFound) { *targ_url = @""; NSLog(@"fnd string not found"); return 0; } NSString *sub_string = [scan_result substringFromIndex : range.location]; range = [sub_string rangeOfString : @" "]; if (range.location != NSNotFound) { sub_string = [sub_string substringToIndex : range.location]; } NSLog(@" FND sub_string = %@", sub_string); *targ_url = sub_string; return [*targ_url length]; } The following is the caller code block, also note that g_scan_result has been declared and initialized (on another source file) as : NSString *g_scan_result = nil; Please do send a comment or answer if you have suggestions or find possible errors in code posted here (or above). Xcode memory tools does not seem to show any memory leak. But it may be because I do not know where to look as am new to the memory tools. { long url_leng = [self analyse_scan_result:result target_url:&targ_url]; NSLog(@" TAR target_url = %@", targ_url); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Scanned Result" message:result delegate:g_alert_view_delegate cancelButtonTitle:@"OK" otherButtonTitles:nil]; if (url_leng) { // ****** The 3 commented off statements // ****** cannot be added without causing // ****** a crash after a few scan result // ****** cycles. // ****** NSString *t_url; if (g_system_status.language_code == 0) [alert addButtonWithTitle : @"Open"]; else if (g_system_status.language_code == 1) [alert addButtonWithTitle : @"Abrir"]; else [alert addButtonWithTitle : @"Open"]; // ****** t_url = g_scan_result; g_scan_result = [targ_url retain]; // ****** [t_url release]; } targ_url = nil; [alert show]; [alert release]; [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(activate_qr_scanner:) userInfo:nil repeats:NO ]; return; }

• How to ensure structures are completly initialized (by name) in GCC?

  - by Steven Spark

  How do I ensure each and every field of my structures are initialized in GCC when using designated initializers? (I'm especially interested in function pointers.) (I'm using C not C++.) Here is an example: typedef struct { int a; int b; } foo_t; typedef struct { void (*Start)(void); void (*Stop)(void); } bar_t; foo_t fooo = { 5 }; foo_t food = { .b=4 }; bar_t baro = { NULL }; bar_t bard = { .Start = NULL }; -Wmissing-field-initializers does not help at all. It works for fooo only in GCC (mingw 4.7.3, 4.8.1), and clang does only marginally better (no warnings for food and bard). I'm sure there is a reason for not producing warnings for designated initializer (even when I explicitly ask for them) but I want/need them. I do not want to initialize structures based on order/position because that is more error prone (for example swapping Start and Stop won't even give any warning). And neither gcc nor clang will give any warning that I failed to explicitly initialize a field (when initializing by name). I also don't want to litter my code with if(x.y==NULL) lines for multiple reasons, one of which is I want compile time warnings and not runtime errors. At least splint will give me warnings on all 4 cases, but unfortunately I cannot use splint all the time (it chokes on some of the code (fails to parse some C99, GCC extensions)). Note: If I'm using a real function instead of NULL GCC will also show a warning for baro (but not bard). I searched google and stack overflow but only found related questions and have not found answer for this specific problem. The best match I have found is 'Ensure that all elements in a structure are initialized' Ensure that all elements in a structure are initialized Which asks pretty much the same question, but has no satisfying answer. Is there a better way dealing with this that I have not mentioned? (Maybe other code analysis tool? Preferably something (free) that can be integrated into Eclipse or Visual Studio...)

• Problems Embedding Video using FCK Editor

  - by Exline

  Hello, I am using FCK Editor 2.6.4 and having problems trying to embed a (non-YouTube) video into a content area. I found this previous question / post: [EDIT -- as a new user, I am only able to post one link in this post. The post in question is titled, "Can I embed video using FCK Editor?") and have investigated all of the proposed solutions, but none of them work properly: 1 -- Using the "Embed Flash" button in the control panel almost works. However, the video I am attempting to add contains a querystring with parameters, like this: http://static.animoto.com/swf/w.swf?w=swf/vp1&e=1275795594&f=mGQklEgxXKs9vfEIdGnWsA&d=132&m=p&r=w&i=m&ct=Homes%20in%20Eagle%20Creek&cu=http://hometoindy.com/eagle-creek-real-estate.php&options= and in using the Flash embed tool, it encodes all of the "&" characters to "&", thus breaking them. If it were just for me, I could manually change them back, but clients who use this will not know how to do that. 2 -- I have installed the YouTube video plugin, and it works great... for YouTube. But it cannot be used to embed non-YouTube videos (it automatically changes the URL to YouTube, no matter what). 3 -- I have installed the EmbedMovies plugin, but it throws a javascript error when attempting to add a video file (such as the above) to a page. (The EmbedMovies plugin page on SourceForge says it has been updated for FCK Editor 2.6, but it does not work.) 4 -- Pasting directly into the editor window (of course) does not work. The only way I've been able to make this work is by pasting into the Source panel, and this is not a good option for clients who are not familiar with HTML. So, is there a good, working plugin for FCK editor that will allow me to quickly and easily embed a video such as the one above into a content area? I don't need to be able to see or preview it in the editor window; I just need it to work when the page is loaded on the front end. Thanks!

• Indexing on only part of a field in MongoDB

  - by Rob Hoare

  Is there a way to create an index on only part of a field in MongoDB, for example on the first 10 characters? I couldn't find it documented (or asked about on here). The MySQL equivalent would be CREATE INDEX part_of_name ON customer (name(10));. Reason: I have a collection with a single field that varies in length from a few characters up to over 1000 characters, average 50 characters. As there are a hundred million or so documents it's going to be hard to fit the full index in memory (testing with 8% of the data the index is already 400MB, according to stats). Indexing just the first part of the field would reduce the index size by about 75%. In most cases the search term is quite short, it's not a full-text search. A work-around would be to add a second field of 10 (lowercased) characters for each item, index that, then add logic to filter the results if the search term is over ten characters (and that extra field is probably needed anyway for case-insensitive searches, unless anybody has a better way). Seems like an ugly way to do it though. [added later] I tried adding the second field, containing the first 12 characters from the main field, lowercased. It wasn't a big success. Previously, the average object size was 50 bytes, but I forgot that includes the _id and other overheads, so my main field length (there was only one) averaged nearer to 30 bytes than 50. Then, the second field index contains the _id and other overheads. Net result (for my 8% sample) is the index on the main field is 415MB and on the 12 byte field is 330MB - only a 20% saving in space, not worthwhile. I could duplicate the entire field (to work around the case insensitive search problem) but realistically it looks like I should reconsider whether MongoDB is the right tool for the job (or just buy more memory and use twice as much disk space). [added even later] This is a typical document, with the source field, and the short lowercased field: { "_id" : ObjectId("505d0e89f56588f20f000041"), "q" : "Continental Airlines", "f" : "continental " } Indexes: db.test.ensureIndex({q:1}); db.test.ensureIndex({f:1}); The 'f" index, working on a shorter field, is 80% of the size of the "q" index. I didn't mean to imply I included the _id in the index, just that it needs to use that somewhere to show where the index will point to, so it's an overhead that probably helps explain why a shorter key makes so little difference. Access to the index will be essentially random, no part of it is more likely to be accessed than any other. Total index size for the full file will likely be 5GB, so it's not extreme for that one index. Adding some other fields for other search cases, and their associated indexes, and copies of data for lower case, does start to add up, which I why I started looking into a more concise index.

• Sign an OpenSSL .CSR with Microsoft Certificate Authority

  - by kce

  I'm in the process of building a Debian FreeRadius server that does 802.1x authentication for domain members. I would like to sign my radius server's SSL certificate (used for EAP-TLS) and leverage the domain's existing PKI. The radius server is joined to domain via Samba and has a machine account as displayed in Active Directory Users and Computers. The domain controller I'm trying to sign my radius server's key against does not have IIS installed so I can't use the preferred Certsrv webpage to generate the certificate. The MMC tools won't work as it can't access the certificate stores on the radius server because they don't exist. This leaves the certreq.exe utility. I'm generating my .CSR with the following command: openssl req -nodes -newkey rsa:1024 -keyout server.key -out server.csr The resulting .CSR: ******@mis-ke-lnx:~/G$ openssl req -text -noout -in mis-radius-lnx.csr Certificate Request: Data: Version: 0 (0x0) Subject: C=US, ST=Alaska, L=CITY, O=ORG, OU=DEPT, CN=ME/emailAddress=MYEMAIL Subject Public Key Info: Public Key Algorithm: rsaEncryption RSA Public Key: (1024 bit) Modulus (1024 bit): 00:a8:b3:0d:4b:3f:fa:a4:5f:78:0c:24:24:23:ac: cf:c5:28:af:af:a2:9b:07:23:67:4c:77:b5:e8:8a: 08:2e:c5:a3:37:e1:05:53:41:f3:4b:e1:56:44:d2: 27:c6:90:df:ae:3b:79:e4:20:c2:e4:d1:3e:22:df: 03:60:08:b7:f0:6b:39:4d:b4:5e:15:f7:1d:90:e8: 46:10:28:38:6a:62:c2:39:80:5a:92:73:37:85:37: d3:3e:57:55:b8:93:a3:43:ac:2b:de:0f:f8:ab:44: 13:8e:48:29:d7:8d:ce:e2:1d:2a:b7:2b:9d:88:ea: 79:64:3f:9a:7b:90:13:87:63 Exponent: 65537 (0x10001) Attributes: a0:00 Signature Algorithm: sha1WithRSAEncryption 35:57:3a:ec:82:fc:0a:8b:90:9a:11:6b:56:e7:a8:e4:91:df: 73:1a:59:d6:5f:90:07:83:46:aa:55:54:1c:f9:28:3e:a6:42: 48:0d:6b:da:58:e4:f5:7f:81:ee:e2:66:71:78:85:bd:7f:6d: 02:b6:9c:32:ad:fa:1f:53:0a:b4:38:25:65:c2:e4:37:00:16: 53:d2:da:f2:ad:cb:92:2b:58:15:f4:ea:02:1c:a3:1c:1f:59: 4b:0f:6c:53:70:ef:47:60:b6:87:c7:2c:39:85:d8:54:84:a1: b4:67:f0:d3:32:f4:8e:b3:76:04:a8:65:48:58:ad:3a:d2:c9: 3d:63 I'm trying to submit my certificate using the following certreq.exe command: certreq -submit -attrib "CertificateTemplate:Machine" server.csr I receive the following error upon doing so: RequestId: 601 Certificate not issued (Denied) Denied by Policy Module The DNS name is unavailable and cannot be added to the Subject Alternate name. 0x8009480f (-2146875377) Certificate Request Processor: The DNS name is unavailable and cannot be added to the Subject Alternate name. 0x8009480f (-2146875377) Denied by Policy Module My certificate authority has the following certificate templates available. If I try to submit by certreq.exe using "CertificiateTemplate:Computer" instead of "CertificateTemplate:Machine" I get an error reporting that "the requested certificate template is not supported by this CA." My google-foo has failed me so far on trying to understand this error... I feel like this should be a relatively simple task as X.509 is X.509 and OpenSSL generates the .CSRs in the required PKCS10 format. I can't be only one out there trying to sign a OpenSSL generated key on a Linux box with a Windows Certificate Authority, so how do I do this (perferably using the off-line certreq.exe tool)?

• Useful software for netbook?

  - by Moayad Mardini

  I'm looking for recommendations of good software that are particularly useful for netbooks. Software that run great on small screens and low CPU/RAM requirments. I'll start off with the following : Operating Systems: Ubuntu Netbook Remix. Easy Peasy: A fork of Ubuntu Netbook Remix that was once called UBuntu EEE. It isn't just for eeePCs though. Definitely worth a look if vanilla Netbook Remix isn't cutting it. (MarkM) Damn Small Linux (Source) Windows 7: With trimming the installation or compressing the Windows directory to fit on an 8GB SSD. (Will Eddins) nLite: A utility to install a lightweight version of Windows XP without the unnecessary components (like Media Player, Internet Explorer, Outlook Express, MSN Explorer, Messenger...). Utilites: TouchFreeze: To disable the touch pad while typing (Source) InSSIDer: Not only does it make it easier to find and keep a wireless connection, but it turns a netbook into the perfect mobile tool for troubleshooting wireless networks. (phenry) AltMove: Adds more functionality to your mouse for interacting with windows. (Rob) ASUS Font Resizer Utility and other tools by ASUS, specific to ASUS Eee PC series. Internet: Run FileZilla FTP client for a small screen : You can hide a lot of FileZilla's interface parts in the View menu, even the directory trees. Go into Settings = Interface and move the message log next to the transfer queue, if you haven't hidden them both or you want to see them. Select a theme with 16x16 icons. (Source) IDEs and Text Editors: Best lightweight IDE/Text Editor: A question on Stack Overflow that has many good suggestions of IDEs and general text editors for programmers. What’s a good linux C/C++ IDE for a low-res screen?: IDEs for Linux-powered netbooks. Online tools: Dropbox: Since the Netbook has limited disk space, you would like to use Cloud Apps like Dropbox and Ubuntu One so that you don't run out of space especially if you are on a holiday. Later when you go back to your desktop with big hard disk,you can take out the files from your dropbox repo. (Manish Sinha) Google products: like Docs, Calendar and Reader (aviraldg) Web sites and software lists: Netbookfiles.com: Netbook specific software downloads. Software Apps to Maximise your Netbook Battery Power: Netbooks are known for their portability. Not only are they small and lightweight but with their increased power efficiency, batteries can last much longer than conventional laptops. This also means you no longer have to carry a power adapter with you! Several brands emphasis the longevity of the battery as a strong selling point, and for those people who travel a lot, it sure is. Free Must-Have Netbook Apps: Finding software for netbooks can present challenges due to limited hard drive space, processor power, RAM, and screen real-estate. That doesn't mean you have to do without essential programs. The apps below cover all the bases -- entertainment, productivity, security, and communication -- without compromising on performance or usability. Best of all, they're free! Useful Netbook Software: With short battery lives and small resolution screens Netbooks, unlike many other computers on the market, could so with some specific software for their use. Now, not all of those I’ve found are specifically designed for Netbooks, but all are relevant. And they’re designed for Windows XP. The question is community wiki, so feel free to edit it. Updated, thank you all for suggestions.

• NetBackup with VSS and Instant Recovery - Failing to delete old snapshots

  - by Jonathan Bourke

  We are attempting to implement Microsoft VSS for snap-shotting in our NetBackup 6.5.3.1 environment. The clients are both 32 & 64 bit Windows 2003 Server. Snapshot parameters are: Instant recovery is enabled Maximum snapshots = 1 Provider type = 1 (System) Snapshot attribute = 1 (Differential) All backups successfully complete, and VSS shadows are successfully created both for the snapshot backup and for the open files (shadow copy components). The Issue: NetBackup is not clearing or overwriting old snapshots with each successive backup. When we list shadows, and shadow storage, it is increasing and increasing. IT is not honouring the Maximum Snapshot setting. The Logs: The bpfis log doesn’t really appear to show any errors other than for methods which we are not employing (VxVM, Flashsnap, etc.).

• Windows 7 Boot to VHD using a VHD clone of the system drive

  - by daveh551

  This seems like a not too difficult problem, and, after several hurdles, I'm maddeningly close. But I can't quite get there. I'm running Windows 7 in development shop. I want to start using VS2010 to work on some stuff that won't be released for awhile. My boss said no beta code on the production machine, but I could run VS2010 for this project IF I could do it in an isolated environment, like a virtual PC. Well, I've used the beta and RC of Win7 on VPC's before, and it was painfully slow because of the VPC environment. But everyone has been singing the praises of Windows 7's boot-to-VHD capability, where only the disk is virtualized, and you're actually running on the hardware. Supposed to be little slower, but nowhere near the speed penalty of VPC. I've spent a fair amount of time getting everything installed the way I want it. So I figured, I'll just clone my system drive using Disk2VHD, and boot off of that, and then install VS2010 onto that. (I keep most of my user data, including all my projects, in a separate partition, so that wouldn't have to be duplicated and would still be available.) Well, I had some difficulties with that, owing mainly to the fact that I was using an old version of Disk2VHD - (get the latest if you're going to try it.) But I did finally get it to boot. (Scott Hanselman has a good blog post on boot to VHD). But it wasn't exactly what I was expecting or hoping for. What I expected was that the VHD would become the C: drive, and the original (physical) C: drive would be either hidden or mounted under a different letter, and thus isolated and protected from any changes. What you actually get is that the VHD becomes the D: drive AND you boot from the D: drive, BUT your original C: drive is still there. Which is sort of okay EXCEPT that the Registry on the VHD is a clone of the Registry on C: drive, and includes many hard-coded references to C:. So the result is that some things come from (and modify) D: (the VHD), but some things come from (and modify) C:. (If you open a cmd prompt and do a SET to look at your environment variables, you will see a mixture of D:\ and C:\ paths.) So I don't really have an isolated environment. Most importantly, %ProgramFiles% is still set to C:\Program Files. What I really need is a tool that can access the registry files on the mounted VHD AS FILES, not as registry entries, and do a global search and replace on all the C:\ in strings to D:. I haven't found such a program. (I've tried to do it with a program called Registry Replace, but, even when running as Administrator, there are certain entries that the Registry won't let you change.) Does anyone know of one? Or any other solution to my problem (other than starting from scratch with a clean VHD and installing Win7 and all my programs on it.)?

• IIS 7.5 + Windows Server 2008 R2 + ASP.NET 4.0 HTTP 500 Error?

  - by Dave

  Hi, I'm having an issue I cannot track down and I have looked through the forums and not found anything that sheds any light. I have a fresh install of a Server 2008 R2 Web that I am trying to load an application I created and tested on a Windows 7 machine running IIS 7.5 using ASP.NET 4.0. Everything works fine on the dev machine. But when I used the Web Deployment tool to move it to the server, I now get a HTTP 500 error without a lot of information: Module AspNetInitClrHostFailureModule Notification BeginRequest Handler StaticFile Error Code 0x80070002 Requested URL http://192.168.1.83:80/ Physical Path C:\JustStreamIt Logon Method Not yet determined Logon User Not yet determined Failed Request Tracing Log Directory C:\inetpub\logs\FailedReqLogFiles And in my trace file I get: view trace Warning -SET_RESPONSE_ERROR_DESCRIPTION ErrorDescription An error message detailing the cause of this specific request failure can be found in the application event log of the web server.

• Problem Disabling Roaming Profiles on Grouped Users

  - by user43207

  I'm having some serious issues getting a group of users to stop using roaming profiles. As expected, I have roaming profiles enabled accross the domain. - But am doing GPO filtering, limiting the scope. I originally had it set to authenticated users for Roaming, but as the domain has branched out to multiple locations, I've limited the scope to only people that are near the central office. The GPO that I have linked filtered to a group I have created that include users that I don't want to have roaming profiles. This GPO is sitting at the root of the domain, with the "Forced" setting enabled, so it should override any setting below it. *On a side note, it is the ONLY GPO that I have set to "Forced" right now. I know the GPO is working, since I can see the original registy settings on a user that logged in under roaming profiles - and then that same user logging in after I made the Group Policy changes, the registry reflects a local profile. But unfortunately, even after making those settings - the user is given a roaming profile on one of the servers. A gpresult of that same user account (after the updated gpo) is listed in the code block below. You can see right at the top of that output, that it is infact dealing with a roaming profile. - And sure enough, on the server that's hosting the file share for roaming profiles, it creates a folder for the user once they log in. For testing purposes, I've deleted all copies of the user's profile, roaming and local. But the problem is still here. - So I'm aparently missing something in the group policy settings on a wider scale. Would anybody be able to point me in the direction of what I'm missing here? *gpresult /r*** Microsoft (R) Windows (R) Operating System Group Policy Result tool v2.0 Copyright (C) Microsoft Corp. 1981-2001 Created On 5/15/2010 at 8:59:00 AM RSOP data for ** on * : Logging Mode OS Configuration: Member Workstation OS Version: 6.1.7600 Site Name: N/A Roaming Profile: \\profiles$** Local Profile: C:\Users*** Connected over a slow link?: No USER SETTINGS CN=*****,OU=*****,OU=*****,OU=*****,DC=*****,DC=***** Last time Group Policy was applied: 5/15/2010 at 8:52:02 AM Group Policy was applied from: *****.*****.com Group Policy slow link threshold: 500 kbps Domain Name: USSLINDSTROM Domain Type: Windows 2000 Applied Group Policy Objects ----------------------------- ForceLocalProfilesOnly InternetExplorer_***** GlobalPasswordPolicy The following GPOs were not applied because they were filtered out ------------------------------------------------------------------- DAgentFirewallExceptions Filtering: Denied (Security) WSAdmin_***** Filtering: Denied (Security) NetlogonFirewallExceptions Filtering: Not Applied (Empty) NetLogon_***** Filtering: Denied (Security) WSUSUpdateScheduleManualInstall Filtering: Denied (Security) WSUSUpdateScheduleDaily_0300 Filtering: Denied (Security) WSUSUpdateScheduleThu_0100 Filtering: Denied (Security) AlternateSSLFirewallExceptions Filtering: Denied (Security) SNMPFirewallExceptions Filtering: Denied (Security) WSUSUpdateScheduleSun_0100 Filtering: Denied (Security) SQLServerFirewallExceptions Filtering: Denied (Security) WSUSUpdateScheduleTue_0100 Filtering: Denied (Security) WSUSUpdateScheduleSat_0100 Filtering: Denied (Security) DisableUAC Filtering: Denied (Security) ICMPFirewallExceptions Filtering: Denied (Security) AdminShareFirewallExceptions Filtering: Denied (Security) GPRefreshInterval Filtering: Denied (Security) ServeRAIDFirewallExceptions Filtering: Denied (Security) WSUSUpdateScheduleFri_0100 Filtering: Denied (Security) BlockFirewallExceptions(8400-8410) Filtering: Denied (Security) WSUSUpdateScheduleWed_0100 Filtering: Denied (Security) Local Group Policy Filtering: Not Applied (Empty) WSUS_***** Filtering: Denied (Security) LogonAsService_Idaho Filtering: Denied (Security) ReportServerFirewallExceptions Filtering: Denied (Security) WSUSUpdateScheduleMon_0100 Filtering: Denied (Security) TFSFirewallExceptions Filtering: Denied (Security) Default Domain Policy Filtering: Not Applied (Empty) DenyServerSideRoamingProfiles Filtering: Denied (Security) ShareConnectionsRemainAlive Filtering: Denied (Security) The user is a part of the following security groups --------------------------------------------------- Domain Users Everyone BUILTIN\Users BUILTIN\Administrators NT AUTHORITY\INTERACTIVE CONSOLE LOGON NT AUTHORITY\Authenticated Users This Organization LOCAL *****Users VPNAccess_***** NetAdmin_***** SiteAdmin_***** WSAdmin_***** VPNAccess_***** LocalProfileOnly_***** NetworkAdmin_***** LocalProfileOnly_***** VPNAccess_***** NetAdmin_***** Domain Admins WSAdmin_***** WSAdmin_***** ***** ***** Schema Admins ***** Enterprise Admins Denied RODC Password Replication Group High Mandatory Level

• Huawei b153 limit of devices

  - by bdecaf

  I set up my home network all through this 3G wifi router. Problem is it only allows 5 devices to connect. That's not much especially if a wifi printer and gaming consoles keep hogging these slots. On the other hand I don't see the point on blocking these devices. They are (should) not doing anything online just intern in my network. The documentation I can find is surpirisingly unhelpful and focuses how to plug the device in a power socket. So what would be my options. Notes: I have already been able to get a shell on the device using ssh. It's running some Busybox. But I fail to find the how and where this limit is enforced/created. Notes 2: Specifically my device is a 3WebCube - unfortunately not specifically marked with the Huawei Model number. Successes so far After enabling ssh in the options I can login: ssh -T [email protected] [email protected]'s password: ------------------------------- -----Welcome to ATP Cli------ ------------------------------- unfortunately because of this -T - the tab key does not work for autocomplete and all inputted commands will be echoed.

• What are the pitfalls of hardlinked files on my desktop PC?

  - by MountainX

  All the identical-content files on my PC are now hardlinked. (My data is completely de-duplicated. It is a consequence of the way I copied my data from my old computer.) What pitfalls do I need to be aware of now that certain actions on one file could silently affect a number of other files? I know that deleting the file I'm working on is not a problem (assuming I deleted it on purpose). It doesn't affect any of the other hardlinked files and I don't see that the delete action would lead to unexpected side effects. Moving or renaming the file is not a problem. I don't see any unexpected consequences. I don't think copying hardlinked files is a problem, but I'm not as confident about any unexpected consequences in this regard. What I have seen is that making a copy (to the same disk) of a hardlinked file with cp keeps the copy hardlinked (i.e., inode number doesn't change in the copy). Copying to another filesystem obviously breaks the hardlink. (I guess one pitfall is forgetting this fact, given that my PC has 3 hard disks.) Changing permissions does affect all linked files. So far this has proven handy. (I made a large number of the hardlinked files read-only.) None of the operations above seem to produce any major unexpected consequences. However, as was pointed out to me by Daniel Beck in a comment, editing or modifying a file can sometimes be a problem. It depends on the tool and maybe the type of edit. (For example, editing small text files using sed seems to always break the link while using nano doesn't.) This introduces the chance that editing one file could affect all the hardlinked files (i.e., alter the original inode). My proposed solution to this is to make all hardlinked files read-only (and that is already mostly the case). If I can't do that for some files, I will unlink those particular files. Is there any problem with this read-only approach? I'm assuming that if I go to edit a file and find it to be read-only, I'll remember to unlink that filename while making it writable. So one pitfall might be forgetting this rule. In that case, I'll have to rely on my backups. Am I correct in the above statements? And what else do I need to know? BTW, I'm running Kubuntu 12.04. I'm also using btrfs. (I have 2 SSD's and 1 HDD in the PC. I will also be adding an external USB HDD. I'm also connected to a network and I mount some NFS shares. I don't assume any of these last bits are relevant to the question, but I'm adding them just in case.) BTW, since I have more than one drive (with separate file systems), to unlink any file all I have to do is copy it to another drive, then move it back. However, using sed also works (in my testing). Here's my script: sed -i 's/\(.\)/\1/' file1 Surprisingly, this even unlinks zero byte files. In my testing it also appears to work on non-text files without any special options. (But I understand that the --binary option might be needed on Windows, MS-DOS and Cygwin.) However, copying to another disk and moving back may be the best way to unlink. For my use-case, unlink command doesn't really "unlink", rather it "removes".

• Determining cause of high NFS/IO utilization without iotop

  - by Matt

  I have a server that is doing an NFSv4 export for user's home directories. There are roughly 25 users (mostly developers/analysts) and about 40 servers mounting the home directory export. Performance is miserable, with users often seeing multi-second lags for simple commands (like ls, or writing a small text file). Sometimes the home directory mount completely hangs for minutes, with users getting "permission denied" errors. The hardware is a Dell R510 with dual E5620 CPUs and 8 GB RAM. There are eight 15k 2.5” 600 GB drives (Seagate ST3600057SS) configured in hardware RAID-6 with a single hot spare. RAID controller is a Dell PERC H700 w/512MB cache (Linux sees this as a LSI MegaSAS 9260). OS is CentOS 5.6, home directory partition is ext3, with options “rw,data=journal,usrquota”. I have the HW RAID configured to present two virtual disks to the OS: /dev/sda for the OS (boot, root and swap partitions), and /dev/sdb for the home directories. What I find curious, and suspicious, is that the sda device often has very high utilization, even though it only contains the OS. I would expect this virtual drive to be idle almost all the time. The system is not swapping, according to "free" and "vmstat". Why would there be major load on this device? Here is a 30-second snapshot from iostat: Time: 09:37:28 AM Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 44.09 0.03 107.76 0.13 607.40 11.27 0.89 8.27 7.27 78.35 sda1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sda2 0.00 44.09 0.03 107.76 0.13 607.40 11.27 0.89 8.27 7.27 78.35 sdb 0.00 2616.53 0.67 157.88 2.80 11098.83 140.04 8.57 54.08 4.21 66.68 sdb1 0.00 2616.53 0.67 157.88 2.80 11098.83 140.04 8.57 54.08 4.21 66.68 dm-0 0.00 0.00 0.03 151.82 0.13 607.26 8.00 1.25 8.23 5.16 78.35 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 0.67 2774.84 2.80 11099.37 8.00 474.30 170.89 0.24 66.84 dm-3 0.00 0.00 0.67 2774.84 2.80 11099.37 8.00 474.30 170.89 0.24 66.84 Looks like iotop is the ideal tool to use to sniff out these kinds of issues. But I'm on CentOS 5.6, which doesn't have a new enough kernel to support that program. I looked at Determining which process is causing heavy disk I/O?, and besides iotop, one of the suggestions said to do a "echo 1 /proc/sys/vm/block_dump". I did that (after directing kernel messages to tempfs). In about 13 minutes I had about 700k reads or writes, roughly half from kjournald and the other half from nfsd: # egrep " kernel: .*(READ|WRITE)" messages | wc -l 768439 # egrep " kernel: kjournald.*(READ|WRITE)" messages | wc -l 403615 # egrep " kernel: nfsd.*(READ|WRITE)" messages | wc -l 314028 For what it's worth, for the last hour, utilization has constantly been over 90% for the home directory drive. My 30-second iostat keeps showing output like this: Time: 09:36:30 PM Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 6.46 0.20 11.33 0.80 71.71 12.58 0.24 20.53 14.37 16.56 sda1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sda2 0.00 6.46 0.20 11.33 0.80 71.71 12.58 0.24 20.53 14.37 16.56 sdb 137.29 7.00 549.92 3.80 22817.19 43.19 82.57 3.02 5.45 1.74 96.32 sdb1 137.29 7.00 549.92 3.80 22817.19 43.19 82.57 3.02 5.45 1.74 96.32 dm-0 0.00 0.00 0.20 17.76 0.80 71.04 8.00 0.38 21.21 9.22 16.57 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 687.47 10.80 22817.19 43.19 65.48 4.62 6.61 1.43 99.81 dm-3 0.00 0.00 687.47 10.80 22817.19 43.19 65.48 4.62 6.61 1.43 99.82

• I want to change DPI with Imagemagick without changing the actual byte-size of the image data

  - by user1694803

  I feel so horribly sorry that I have to ask this question here, but after hours of researching how to do an actually very simple task I'm still failing... In Gimp there is a very simple way to do what I want. I only have the German dialog installed but I'll try to translate it. I'm talking about going to "Picture-PrintingSize" and then adjusting the Values "X-Resolution" and "Y-Resolution" which are known to me as so called DPI values. You can also choose the format which by default is "Pixel/Inch". (In German the dialog is "Bild-Druckgröße" and there "X-Auflösung" and "Y-Auflösung") Ok, the values there are often "72" by default. When I change them to e.g. "300" this has the effect that the image stays the same on the computer, but if I print it, it will be smaller if you look at it, but all the details are still there, just smaller - it has a higher resolution on the printed paper (but smaller size... which is fine for me). I am often doing that when I am working with LaTeX, or to be exact with the command "pdflatex" on a recent Ubuntu-Machine. When I'm doing the above process with Gimp manually everything works just fine. The images will appear smaller in the resulting PDF but with high printing quality. What I am trying to do is to automate the process of going into Gimp and adjusting the DPI values. Since Imagemagick is known to be superb and I used it for many other tasks I tried to achieve my goal with this tool. But it does just not do what I want. After trying a lot of things I think this actually is be the command that should be my friend: convert input.png -density 300 output.png This should set the DPI to 300, as I can read everywhere in the web. It seems to work. When I check the file it stays the same. file input.png output.png input.png: PNG image data, 611 x 453, 8-bit grayscale, non-interlaced output.png: PNG image data, 611 x 453, 8-bit grayscale, non-interlaced When I use this command, it seems like it did what I wanted: identify -verbose output.png | grep 300 Resolution: 300x300 PNG:pHYs : x_res=300, y_res=300, units=0 (Funny enough, the same output comes for input.png which confuses me... so this might be the wrong parameters to watch?) But when I now render my TeX with "pdflatex" the image is still big and blurry. Also when I open the image with Gimp again the DPI values are set to "72" instead of "300". So there actually was no effect at all. Now what is the problem here. Am I getting something completely wrong? I can't be that wrong since everything works just fine with Gimp... Thanks for any help in this. I am also open to other automated solutions which are easily done on a Linux system...

• Cannot ping host stale ARP cache?

  - by gkchicago

  I am having a strange issue with a Debian (Lenny/Linux 2.6.26-2-amd64) that has been driving me nuts. On some machines within my network I can ping the host in question just fine, other times I have to manually hard-code the ARP ethernet address for the IP in order to establish connectivity. I've finally worked it down to somehow involving ARP. I just found how to fix it in a way that made it work but I'm looking for help explaining this issue and also I don't trust my fix to be permanent.. My thought process has been the following but I just can't make any sense out of it: Could it be the card? (Intel 82555 rev 4) Could it be because there are two network cards? (Default route is eth0) Could it be because of the network aliases? Lenny? AMD x86_64? Argh..

• Users loggin to 3Com switches authenticated by radius not getting admin priv and no access available

  - by 3D1L

  Hi, Following the setup that I have for my Cisco devices, I got some basic level of functionality authenticating users that loggin to 3Com switches authenticated against a RADIUS server. Problem is that I can not get the user to obtain admin privileges. I'm using Microsoft's IAS service. According to 3Com documentation when configuring the access policy on IAS the value of 010600000003 have to be used to specify admin access level. That value have to be input in the Dial-in profile section: 010600000003 - indicates admin privileges 010600000002 - manager 010600000001 - monitor 010600000000 - visitor Here is the configuration on the switch: radius scheme system server-type standard primary authentication XXX.XXX.XXX.XXX accounting optional key authentication XXXXXX key accounting XXXXXX domain system scheme radius-scheme system local-user admin service-type ssh telnet terminal level 3 local-user manager service-type ssh telnet terminal level 2 local-user monitor service-type ssh telnet terminal level 1 The configuration is working with the IAS server because I can check user login events with the Eventviewer tool. Here is the output of the DISPLAY RADIUS command at the switch: [4500]disp radius SchemeName =system Index=0 Type=standard Primary Auth IP =XXX.XXX.XXX.XXX Port=1645 State=active Primary Acct IP =127.0.0.1 Port=1646 State=active Second Auth IP =0.0.0.0 Port=1812 State=block Second Acct IP =0.0.0.0 Port=1813 State=block Auth Server Encryption Key= XXXXXX Acct Server Encryption Key= XXXXXX Accounting method = optional TimeOutValue(in second)=3 RetryTimes=3 RealtimeACCT(in minute)=12 Permitted send realtime PKT failed counts =5 Retry sending times of noresponse acct-stop-PKT =500 Quiet-interval(min) =5 Username format =without-domain Data flow unit =Byte Packet unit =1 Total 1 RADIUS scheme(s). 1 listed Here is the output of the DISPLAY DOMAIN and DISPLAY CONNECTION commands after users log into the switch: [4500]display domain 0 Domain = system State = Active RADIUS Scheme = system Access-limit = Disable Domain User Template: Idle-cut = Disable Self-service = Disable Messenger Time = Disable Default Domain Name: system Total 1 domain(s).1 listed.

The switch have 3 local accounts but none of them works. How can I specify the switch to use the local accounts in case that the RADIUS service is not available?

• Making sense of S.M.A.R.T

  - by James

  First of all, I think everyone knows that hard drives fail a lot more than the manufacturers would like to admit. Google did a study that indicates that certain raw data attributes that the S.M.A.R.T status of hard drives reports can have a strong correlation with the future failure of the drive. We find, for example, that after their first scan error, drives are 39 times more likely to fail within 60 days than drives with no such errors. First errors in re- allocations, offline reallocations, and probational counts are also strongly correlated to higher failure probabil- ities. Despite those strong correlations, we find that failure prediction models based on SMART parameters alone are likely to be severely limited in their prediction accuracy, given that a large fraction of our failed drives have shown no SMART error signals whatsoever. Seagate seems like it is trying to obscure this information about their drives by claiming that only their software can accurately determine the accurate status of their drive and by the way their software will not tell you the raw data values for the S.M.A.R.T attributes. Western digital has made no such claim to my knowledge but their status reporting tool does not appear to report raw data values either. I've been using HDtune and smartctl from smartmontools in order to gather the raw data values for each attribute. I've found that indeed... I am comparing apples to oranges when it comes to certain attributes. I've found for example that most Seagate drives will report that they have many millions of read errors while western digital 99% of the time shows 0 for read errors. I've also found that Seagate will report many millions of seek errors while Western Digital always seems to report 0. Now for my question. How do I normalize this data? Is Seagate producing millions of errors while Western digital is producing none? Wikipedia's article on S.M.A.R.T status says that manufacturers have different ways of reporting this data. Here is my hypothesis: I think I found a way to normalize (is that the right term?) the data. Seagate drives have an additional attribute that Western Digital drives do not have (Hardware ECC Recovered). When you subtract the Read error count from the ECC Recovered count, you'll probably end up with 0. This seems to be equivalent to Western Digitals reported "Read Error" count. This means that Western Digital only reports read errors that it cannot correct while Seagate counts up all read errors and tells you how many of those it was able to fix. I had a Seagate drive where the ECC Recovered count was less than the Read error count and I noticed that many of my files were becoming corrupt. This is how I came up with my hypothesis. The millions of seek errors that Seagate produces are still a mystery to me. Please confirm or correct my hypothesis if you have additional information. Here is the smart status of my western digital drive just so you can see what I'm talking about: james@ubuntu:~$ sudo smartctl -a /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: WDC WD1001FALS-00E3A0 Serial Number: WD-WCATR0258512 Firmware Version: 05.01D05 User Capacity: 1,000,204,886,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Thu Jun 10 19:52:28 2010 PDT SMART support is: Available - device has SMART capability.

• Windows 7 BSOD - ntoskrnl?

  - by Ken Mason

  2 new HP Pavilion notebooks with 7 Home Premium pre-loaded with Norton. My first act was to use the Norton Removal Tool and load ZoneAlarm free and AVG Free. Frequent random BSOD's ever since...I found my way into Debug and have had various reports regarding ntoskrnl, depending on the status of symbols. It's been many years since I played with (DOS 3.x) debug, so this has been a considerable fumble. Excerpts follow and any insights would be greatly appreciated, as I am not a developer: ADDITIONAL_DEBUG_TEXT: Use '!findthebuild' command to search for the target build information.

• VirtualBox - Public Static IP for a Debian Guest on a Dedicated Server

  - by user86296

  Goal: I want to run a Debian-squeeze-Guest in VirtualBox and it's own public static ip. I found tons of threads about this topic, but all in all I'm now trying for 10 hours (reading the manual, the forums, trying to learn about networking concepts & commands) to give a Guest his own public static ip (so that the Guest is similar to a vServer you can order from a hosting company), but wasn't able to. Since I'm a big noob as far as networking stuff is concerned, I'm probably doing something wrong.(please bear with me :-) ) Situation: VirtualBox 4.0.10 (headless no gui) is running on a dedicated Debian-Server, the Guest OS is Debian as well. The server has a static ip and I ordered an additional ip for a VM. Problem description: Upto now I was able to use NAT to access the VM from the outside and to setup an internal network between several Guests and all of this worked very well. When setting NIC 1 to bridged and configuring a public static ip on the guest, the guest was unpingable. (neither from outside, nor from the host) I could connect to the guest via the internal network, from another vm, though. ( VBoxManage controlvm VMGuest nic1 bridged eth0 ) ( configuration attempt of static-ip on the guest '/etc/network/interfaces' is below) Please let me know what I'm doing wrong, or what I can try to get it to work, or if you need more info. I think I've read that with a current VirtualBox-version for bridged networking no special host-configuration is necessary, is that accurate, or might that be the problem? Additional Info Info I got from the hosting company about the additional IP Please note that you can use the IP address only for this server.

• Upgraded Ubuntu, all drives in one zpool marked unavailable

  - by Matt Sieker

  I just upgraded Ubuntu 14.04, and I had two ZFS pools on the server. There was some minor issue with me fighting with the ZFS driver and the kernel version, but that's worked out now. One pool came online, and mounted fine. The other didn't. The main difference between the tool is one was just a pool of disks (video/music storage), and the other was a raidz set (documents, etc) I've already attempted exporting and re-importing the pool, to no avail, attempting to import gets me this: root@kyou:/home/matt# zpool import -fFX -d /dev/disk/by-id/ pool: storage id: 15855792916570596778 state: UNAVAIL status: One or more devices contains corrupted data. action: The pool cannot be imported due to damaged devices or data. see: http://zfsonlinux.org/msg/ZFS-8000-5E config: storage UNAVAIL insufficient replicas raidz1-0 UNAVAIL insufficient replicas ata-SAMSUNG_HD103SJ_S246J90B134910 UNAVAIL ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523 UNAVAIL ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969 UNAVAIL The symlinks for those in /dev/disk/by-id also exist: root@kyou:/home/matt# ls -l /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910* /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51* lrwxrwxrwx 1 root root 9 May 27 19:31 /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910 -> ../../sdb lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910-part1 -> ../../sdb1 lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910-part9 -> ../../sdb9 lrwxrwxrwx 1 root root 9 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523 -> ../../sdd lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523-part1 -> ../../sdd1 lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523-part9 -> ../../sdd9 lrwxrwxrwx 1 root root 9 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969 -> ../../sde lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969-part1 -> ../../sde1 lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969-part9 -> ../../sde9 Inspecting the various /dev/sd* devices listed, they appear to be the correct ones (The 3 1TB drives that were in a raidz array). I've run zdb -l on each drive, dumping it to a file, and running a diff. The only difference on the 3 are the guid fields (Which I assume is expected). All 3 labels on each one are basically identical, and are as follows: version: 5000 name: 'storage' state: 0 txg: 4 pool_guid: 15855792916570596778 hostname: 'kyou' top_guid: 1683909657511667860 guid: 8815283814047599968 vdev_children: 1 vdev_tree: type: 'raidz' id: 0 guid: 1683909657511667860 nparity: 1 metaslab_array: 33 metaslab_shift: 34 ashift: 9 asize: 3000569954304 is_log: 0 create_txg: 4 children[0]: type: 'disk' id: 0 guid: 8815283814047599968 path: '/dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910-part1' whole_disk: 1 create_txg: 4 children[1]: type: 'disk' id: 1 guid: 18036424618735999728 path: '/dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523-part1' whole_disk: 1 create_txg: 4 children[2]: type: 'disk' id: 2 guid: 10307555127976192266 path: '/dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969-part1' whole_disk: 1 create_txg: 4 features_for_read: Stupidly, I do not have a recent backup of this pool. However, the pool was fine before reboot, and Linux sees the disks fine (I have smartctl running now to double check) So, in summary: I upgraded Ubuntu, and lost access to one of my two zpools. The difference between the pools is the one that came up was JBOD, the other was zraid. All drives in the unmountable zpool are marked UNAVAIL, with no notes for corrupted data The pools were both created with disks referenced from /dev/disk/by-id/. Symlinks from /dev/disk/by-id to the various /dev/sd devices seems to be correct zdb can read the labels from the drives. Pool has already been attempted to be exported/imported, and isn't able to import again. Is there some sort of black magic I can invoke via zpool/zfs to bring these disks back into a reasonable array? Can I run zpool create zraid ... without losing my data? Is my data gone anyhow?

• NetBackup with VSS and Instant Recovery - Failing to delete old snapshots

  - by Jonathan Bourke

  We are attempting to implement Microsoft VSS for snap-shotting in our NetBackup 6.5.3.1 environment. The clients are both 32 & 64 bit Windows 2003 Server. Snapshot parameters are: Instant recovery is enabled Maximum snapshots = 1 Provider type = 1 (System) Snapshot attribute = 1 (Differential) All backups successfully complete, and VSS shadows are successfully created both for the snapshot backup and for the open files (shadow copy components). The Issue: NetBackup is not clearing or overwriting old snapshots with each successive backup. When we list shadows, and shadow storage, it is increasing and increasing. IT is not honouring the Maximum Snapshot setting. The Logs: The bpfis log doesn’t really appear to show any errors other than for methods which we are not employing (VxVM, Flashsnap, etc.). A section is as follows: 11:54:10.744 [348.4724] <2> logparams: D:\Program Files\Veritas\NetBackup\bin\bpfis.exe delete -nbu -id htpststr001.san.mgmt.det_1248918143 -bpstart_to 300 -bpend_to 300 -clnt htpststr001.san.mgmt.det 11:54:10.744 [348.4724] <4> bpfis: INF - BACKUP START 348 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: VfMS error 10; see following messages: 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: Non-fatal method error was reported 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: vfm_configure_fi_one: method: FlashSnap, type: FIM, function: FlashSnap_init 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: VfMS method error 3; see following message: 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: FlashSnap_init: Veritas Volume Manager not installed. 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: VfMS error 10; see following messages: 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: Non-fatal method error was reported 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: vfm_configure_fi_one: method: vxvm, type: FIM, function: vxvm_init 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: VfMS method error 3; see following message: 11:54:11.713 [348.4724] <8> onlfi_initialize_vfms: vxvm_init: Veritas Volume Manager not installed. 11:54:11.713 [348.4724] <4> onlfi_thaw: Thawing C:\ using snapshot method VSS. 11:54:11.713 [348.4724] <2> onlfi_vfms_logf: vfm_thaw: delete snapshot ... 11:54:11.744 [348.4724] <2> onlfi_vfms_logf: snapshot services: emcclariionfi:Thu Jul 30 2009 11:54:11.744000 <Thread id - 4724> Unable to import any login credentials for any appliances. 11:54:11.760 [348.4724] <2> onlfi_vfms_logf: snapshot services: hpevafi:Thu Jul 30 2009 11:54:11.760000 <Thread id - 4724> CHpEvaPlugin::init: CLI tool is not installed. 11:54:11.760 [348.4724] <2> onlfi_vfms_logf: snapshot services: hpmsafi:Thu Jul 30 2009 11:54:11.760000 <Thread id - 4724> No array mangement credentials are available in configuration file. 11:54:13.806 [348.4724] <4> onlfi_thaw: do_thaw return value: 0 11:54:13.806 [348.4724] <4> onlfi_thaw: Thawing D:\ using snapshot method VSS. 11:54:15.806 [348.4724] <4> onlfi_thaw: do_thaw return value: 0 11:54:19.806 [348.4724] <2> fis_delete_id: removing D:\Program Files\Veritas\NetBackup\online_util\fi_cntl\bpfis.fim.htpststr001.san.mgmt.det_1248918143.0 11:54:19.806 [348.4724] <2> fis_delete_id: removing D:\Program Files\Veritas\NetBackup\online_util\fi_cntl\bpfis.fim.htpststr001.san.mgmt.det_1248918143.0.fiid 11:54:19.853 [348.4724] <4> bpfis: INF - EXIT STATUS 0: the requested operation was successfully completed The Question: Has anyone any experience of NetBackup / VSS not clearing snapshots after backups? We will ultimately be using a HP EVA for the snapshots, but we want to ensure correct functioning at a VSS level before we go further.

• Moving users folder on Windows-7 to another partition - bad idea?

  - by Donat

  Hi, I'd like to re-submit here a question posted by Benjol on Aug 17at 5:57 "Moving users folder on Windows Vista to another partition - bad idea?" (I can't post one than one link until I earn "10 reputation" and removed my "answer" there to post my follow-up questions here). I am anxiously getting ready at long last to to carry out a clean install (using custom install option) from Vista to Windows-7 Home Premium 64bit with the free upgrade I received late October. For my Vista system I successfully set-up last Summer a multi-partitions scheme with Users and Program Data on a a different partition than the operating system (see link below, and its subsequent links in my comment for details). http://tuts4tech.net/2009/08/05/windows-7-move-the-users-and-program-files-directories-to-a-different-partition/comment-page-1/#comment-562 I was planning a similar set-up for windows 7, a little more streamlined, with OS, Program Files on C:, Users and Program Data on D:, and TV media recording on a separate partition. Reading the Question submitted by Benjol, I am second guessing too. Is moving Users and Program Data on a different partition than the default primary partition with OS and Program Files such a good idea? The couple of people I talked to at the official Microsoft Windows 7 booth at CES 2010 gave the same answer to the intention of moving the Users profile folder to another partition. In a nutshell, they all told me that they used to do this in XP and less in Vista but not anymore with Windows 7... "It is stable, after two months still no problem" I had the feeling it was a scripted answer to emphasize how Windows 7 is so stable and efficient... (Will Windows-7 system not become bugged down over the course of several months to a year or two? Only time will tell) Long story short, I share the same view than Benjol expressed with respect to being "able to backup and restore system and user data independently." I just received a 2TB usb2, eSATA external hard drive as a back-up drive, which includes NTI Shadow 4 (4.1.0.150) for back-up solution. I took note of the issue with NTUSER.DAT and I will read more about Volume Shadow Copy Service (VSS) for Windows 7. I am willing to put the effort if placing Users and Program Data on a different partition would allow to restore a fresher OS+Program image when the system gets bugged down. Questions: Is it such a bad idea? What is the "easy route" referred by Benjol in his post? Is it to just relocate folders to another partition using the Folder property tool? (It is not practical for several users and might not provide a straightforward restore process of just OS and Program Files when needed.) I am starting to learn about Windows 7 libraries. Would Windows 7 libraries be another alternative to achieve this? All this reading to decide how to organize the partition scheme for my custom system is starting to be confusing. I apologize for this lengthy Question. It is my first day here on SuperUser and I am just learning how different from a discussion thread it is. Thank you in advance for all your suggestions and comments. Donat
