  • Nagios Check_hpjd giving me problems!

    - by Mister IT Guru
    When I run the following [root@host plugins]# ./check_hpjd -H printer1.mydomain.com : Timeout from host printer1.mydomain.com I have Net-snmp installed on my system, I noted that i didn't have net-snmp-utils installed, and then I was able to run [root@host plugins]# snmpwalk -Os -c public -v 1 printer1.mydomain.com system sysDescr.0 = STRING: HP ETHERNET MULTI-ENVIRONMENT sysObjectID.0 = OID: enterprises.11.2.3.9.1 sysUpTimeInstance = Timeticks: (325408663) 37 days, 15:54:46.63 sysContact.0 = STRING: sysName.0 = STRING: printer1 sysLocation.0 = STRING: sysServices.0 = INTEGER: 72 So I know that the printer is working as expected, (as far as SNMP is concerned). But when I run [root@host plugins]# ./check_hpjd -H printer1.mydomain.com -C public Error in packet () I get this error - From what I've tried so far, I know my host can communicate via SNMP, I know the printer responds via SNMP, so I guess I'm left to look at the plug-in, which I will be checking up on. I'm new to SNMP, I am investigating this with my good friend Google search, but I am on a learning curve here, so please forgive my questions if they sound stupid,

  • Is there a way to remove duplicate emails from a remote account?

    - by Mister IT Guru
    I have a user who has multiple duplicated emails across multiple folders on his IMAP account. How he managed to create them is beyond me, but mine is not to reason why, just to fix it! Can anyone recommend an application that I may use to remove the duplicates. (we're talking mailboxes in excess of 9G, and it's a remote server) I don't mind what OS I have to use to clean up the mailbox, I'm just looking for some recommendations. Thanks

  • PS/2 vs USB keyboards: performance and energy consumption

    - by Mister Smith
    As far as I know, PS/2 keyboards are interrupt driven, while USB are polled. Typically a PS/2 keyboard was assigned IRQ_1 on Windows. I'm no hardware expert, but at a first glance seems like the PS/2 keyboards are more efficient. So here are my questions: On modern day computers, are PS/2 keyboard better (or faster), and if so, would it be noticeable at all? (e.g.: in gaming) Since they don't need polling, do PS/2 keyboards save energy compared to USB? (notice I'm not talking only about the peripheral here, but about the overall computer energy consumption). In case PS/2 had any advantage over USB, would adding a PS/2 adapter to my USB keyboard make the device as good as an actual PS/2 keyboard? Conversely, would adding a USB adapter to a PS/2 make it as bad as a USB KB? Thanks in advance.

  • Linux Security/Sysadmin Courses in London?

    - by mister k
    Hi, My employer has offered to send me on a couple of training courses and I'm just looking for some recommendations. I'm mainly looking to improve my security and general sysadmin skills. I would like to do something focused on UNIX as I mainly work with Linux boxes (but also a couple of FreeBSD boxes). I don't want to do a study-from-home course, so I would need to find somewhere based in London. It would be great to hear from anyone who has some experience with this kind of course. The courses I've found so far are: www.learningtree.co.uk/courses/uk433.htm www.city.ac.uk/cae/cfa/computing/systems_it/linux.html www.city.ac.uk/cae/cfa/computing/systems_it/unix_tools_ss.html I'm not sure the City University courses are advanced enough as I already have experience... Thanks!

  • IP6 seems to be enabled - How do I configure it without interfering with IP4?

    - by Mister IT Guru
    I noticed that some of my Centos boxes have IP6 enabled, and seem to have addresses. I have no problem with this, but I would like to get a handle on it, and even connect to them using IP6. This would really help if for any reason DHCP has a hiccup. But I'm a bit lost as to where the configuration on my CentOS box is. (I am also on google researching this, but I like server fault! :) ) I am hoping that I would be able to log into this via the VPN because every now and then that DHCP device has a bad morning, and needs to be restarted. (I'm also looking into this issue, but someone else handles that, management separation gone mad!) It's a remote client, so it would be a lot easier for me to connect to these systems which seem to self configure, to use that as a pivot via ssh tunnels to get to other remote devices to continue to manage them, while out main route is fixed. I guess, my questions are How can I configure IP6 without interfering with IP4, and On CentOS, can I influence this auto configuration I seem to be seeing?

  • 3000 videos songs... some are loud in voice & some low.. I want to make them equal (equal in volume only)

    - by Mister.9
    I have thousands Video flv/avi files, which are all songs only. Some of them are high in volume and some are low. Every time the song ends I have to up or down the volume at once..to escape my ears ruined by headphones... and by woofers, save my life from my neighbor sleeping after hard-earning all the day long. :-( Any idea to make all files sound equal? Does such kind of application/software exist? Any converter that may convert all audio files into same volume? I know iTunes has sound-check option but can it convert? If I want to write CDs, does any burner have the feature like this, to burn in equal sound? If yes, suggest something for me... For, I am really really worried... It would be a great help..... Hoping your kind reply, Thanks in advance! (I am I am John.martin188@yahoo for having mails also in this regard)

  • What are the minimum required modules to run WordPress

    - by Mister IT Guru
    Recently a 'consultant' came in to talk to bean counters at my place of employment, with regards to being more efficient with our IT infrastructure. They suggested to be more efficient we should only load the Apache modules that are required on our web servers. (This is just 1 of 1Ks of suggestions). The Bean Counters are very excited, and prepared for me to spend the time to investigate this avenue of cost cutting. I don't mind this mundane exercise, I see it as a learning experience! I guess this leads me to the actual question: How can I determine the minimum required apache modules for a PHP based application without actually going through the code, or plain old trial and error?

  • Copied XEN vm to new host - boots up asking to fix the HD (win2003 guest)

    - by Mister IT Guru
    I have an old box running CentOS 5.4, and XEN. It has a 2003 Guest that I wish to move over to another CentOS box running XEN. I stopped the machine, and have SCP'd the HD image files of the guest to the new host. I ran md5sum on the files, and they are identical. When I configure a new Guest, it fires up, but windows fails to boot asking to fix the system instead. The HD are identical, so I'm guessing there is something that I missed. I don't want to go through this procedure, because the system needs to be identical. How can I get one VM to run seamlessly on another host? Any ideas, and comments are 100% appreciated. Thank You

    - by andyleonard
    No it's not 1 Apr. Joel Spolsky ( Blog - @spolsky ) announced recently he is retiring from blogging 17 Mar 2010 . Reading Joel on Software always makes me think. Mr. Spolsky pioneered a writing style. Along the way he empowered developers, encouraging them to speak up about the manifold misconceptions of our trade. I will miss Mr. Spolsky's writings.

  • Open source engagement as a professional reference

    - by Martin
    if one commits his or her time to an open source project, he or she may be invest a substantial amount of time without getting paid. As much as altruism is appreciable, I wonder whether it "counts" as an activity which can be shown and is valued in job applications. If the company is worth your time and working power, which it should be in my honest opinion. So I wonder whether there is something like a common practice in open source projects for this matters. Say, something like Mr. Martin has been working on our project for five years and has contributed this and that,[...] I we wish him very best for his future. Mr. ChiefofProject I think this is a just concern. Do have experiences you can share?

  • What is the best option for reading Java property files?

    - by Mr Morgan
    Hello I have an application which uses a servlet to read an intialization parameter from web.xml for the location of a property file. The serlvet then creates an instance of a class which stores the location of the file for other programs to read as required. This class has appropriate get and set methods. But my question concerns access to the properties: should the physical property file be read by each program as at runtime or should the properties be stored in memory instead? The properties are not currently altered at runtime but this could change? I've seen various alternative approaches but am not sure which is best. Thanks Mr Morgan

  • Getting the count of rows in a Java resultset

    - by Mr Morgan
    Hello Does anyone know a better way of getting the number of rows in a Java resultset returned from a MySQL database? I'm currently using this: public static int getResultSetRowCount(ResultSet resultSet) { int size = 0; try { resultSet.last(); size = resultSet.getRow(); resultSet.beforeFirst(); } catch(Exception ex) { return 0; } return size; } But am open to alternatives. The resultset returned is not going to be the total number of rows read from the database so I don;t think I can use SQL COUNT. Thanks Mr Morgan.

  • Use of Java constructors in persistent entities

    - by Mr Morgan
    Hello I'm new to JPA and using persistence in Java anyway and I have two questions I can't quite work out: I have generated tags as: @JoinColumn(name = "UserName", referencedColumnName = "UserName") @ManyToOne(optional = false) private User userName; @JoinColumn(name = "DatasetNo", referencedColumnName = "DatasetNo") @ManyToOne(optional = false) private Dataset datasetNo; But in one of the constructors for the class, no reference is made to columns UserName or DatasetNo whereas all other columns in the class are referenced in the constructor. Can anyone tell me why this is? Both columns UserName and DatasetNo are 'foreign keys' on the entity Visualisation which corresponds to a database table of the same name. I can't quite work out the ORM. And when using entity classes, or POJO, is it better to have class variables like: private User userName; Where an instance of a class is specified or simply the key of that class instance like: private String userName; Thanks Mr Morgan.

  • Filter Calendar view SharePoint WWS 3.0

    - by lerac
    Hi all, I have a SP site with a calendarview and would like to filter this on the basis of the current user. Don't be afraid I already figured out how do to this with a list customizing some excisting jScripts and working with Content Editor WebPart. Yet this jScript does not work in a Calendar. To paint a picture I have columns like: Judge1 Lawyer Clerk (example). Underneath these columns there are names ofcourse. However these are not shown in Calendar view, so it is hard to filter on something that is not displayed only the casenumbers. Now I've been thinking (not always wise) perhaps I can adjust the aspx page of calendar/list by adjusting a filter I applied in SharePoint. This would also solve the issue of displaying all the content before it filters with Java, since it should not be possible for users to see the entire listcontent (security). I went to Modify list view and created a filter where judge1 = Mr. J. Jenkins. Then I went to SharePoint Designer and opend the Calendar aspx page. To my expectation I found Mr. J. Jenkins with the following code: Since I can't display image because i'm new, not very handy discrimination I have to give you a url. Code can't be pasted either is completely messes it up even with codemode on. Hyperlink CODE IMAGE Keep in mind I just posted a very tiny part of the code (only the part I want to change). Now I have no idea what kind of code this is above this text (SP wss 3.0 uses for aspx pages), but I would like to change Mr. J. Jenkins into a jScript var/val. Since I already managed to get the current user that is logged in content. var user = jP.getUserProfile(); var userinfspvalue = user.Department; There is more code around that one 2 ofcourse, yet to give you a picture. The var userinfspvalue is what I would like to replace the text Mr. J. Jenkins into. This would mean the calendar would be dynamically filtered based upon the current user that is logged on. Have no idea what is possible, perhaps there is a better solution who knows... Do you know? Thank you so much ahead!

  • Confused about ASP.NET AJAX, AJAX, jQUERY and javascript

    - by Mr.Y
    Yesterday, I read couple of chapters on ASP.NET Ajax,and jQuery from my ASP.NET 4.0 book and I found those frameworks pretty interesting and decide to learn more about it. Today, I borrow some books from library on AJAX and Javascript. It seems ASP.NET ajax is different from Ajax and jQuery seems like the "new" javascript. Is that means I can skip javascript and learn jQUERY directly? On the other hand, the Ajax(non asp.net) book I borrow from library seems apply to the client side web programming only and looks quite difference from what I learned from ASP.NET AJAX. If I'm a ASP.NET developer I guess I should stick with ASP.NET AJAX instead of client side AJAX right? What about PHP? Is there a "PHP AJAX" similar to ASP.NET AJAX? It's not that I'm "lazy" to learn other tools, but I just want to focus on the right ones. Thx. The more I going deep

  • SQL SERVER – Implementing IF … THEN in SQL SERVER with CASE Statements

    - by Pinal Dave
    Here is the question I received the other day in email. “I have business logic in my .net code and we use lots of IF … ELSE logic in our code. I want to move the logic to Stored Procedure. How do I convert the logic of the IF…ELSE to T-SQL. Please help.” I have previously received this answer few times. As data grows the performance problems grows more as well. Here is the how you can convert the logic of IF…ELSE in to CASE statement of SQL Server. Here are few of the examples: Example 1: If you are logic is as following: IF -1 < 1 THEN ‘TRUE’ ELSE ‘FALSE’ You can just use CASE statement as follows: -- SQL Server 2008 and earlier version solution SELECT CASE WHEN -1 < 1 THEN 'TRUE' ELSE 'FALSE' END AS Result GO -- SQL Server 2012 solution SELECT IIF ( -1 < 1, 'TRUE', 'FALSE' ) AS Result; GO If you are interested further about how IIF of SQL Server 2012 works read the blog post which I have written earlier this year . Well, in our example the condition which we have used is pretty simple but in the real world the logic can very complex. Let us see two different methods of how we an do CASE statement when we have logic based on the column of the table. Example 2: If you are logic is as following: IF BusinessEntityID < 10 THEN FirstName ELSE IF BusinessEntityID > 10 THEN PersonType FROM Person.Person p You can convert the same in the T-SQL as follows: SELECT CASE WHEN BusinessEntityID < 10 THEN FirstName WHEN BusinessEntityID > 10 THEN PersonType END AS Col, BusinessEntityID, Title, PersonType FROM Person.Person p However, if your logic is based on multiple column and conditions are complicated, you can follow the example 3. Example 3: If you are logic is as following: IF BusinessEntityID < 10 THEN FirstName ELSE IF BusinessEntityID > 10 AND Title IS NOT NULL THEN PersonType ELSE IF Title = 'Mr.' THEN 'Mister' ELSE 'No Idea' FROM Person.Person p You can convert the same in the T-SQL as follows: SELECT CASE WHEN BusinessEntityID < 10 THEN FirstName WHEN BusinessEntityID > 10 AND Title IS NOT NULL THEN PersonType WHEN Title = 'Mr.' THEN 'Mister' ELSE 'No Idea' END AS Col, BusinessEntityID, Title, PersonType FROM Person.Person p I hope this solution is good enough to convert the IF…ELSE logic to CASE Statement in SQL Server. Let me know if you need further information about the same.

  • Error when plugging iPod Touch into MacBook

    Whenever I plug my iPod Touch (2nd gen) into my MacBook running Ubuntu 10.10 I get the following error: DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus) It will show up in the file browser but whenever I try to mount it I get that error. EDIT: I thought that this might be because I had it plugged into a dock, but I tried plugging it in directly to the MacBook with the USB Cable and it still does not work, same error message.
