Have I got the right tools?

Hi all,
I need to acquire/buy the following tools for a lot of my network related activities. I need:
1) A tool that checks for cable splits/breaks, DHCP functionality and troubleshoot basic network problems and last but not least should be very portable. Ofcourse this could do other things but this is a minimal scope of functionality that should be supported.
2) A protocol anaylzer.
Upon doing some research I have basciallly outlined the fluke netool device and wireshark (formerly ethereal). I wanted to know if this is a good choice and if you guys have any better recommendations.
Thanks a lot.

For #1 I use the Fluke one-touch and for #2 Wireshark, I am happy with both and used them both for years.

  • Have I got the right set-

    I'm a VERY new owner of a Zen Touch 40gb. I have bought it because I teach dancing and wanted it to replace my portable stereo that I've borrowed from my daughter and hasn't got too much volume to it. I bought the Creative Megaworks 2. speaker system to go with it and have plugged the player into the speakers via the headphone socket and it sounds quite loud when you've got the volume up on the player. I am wondering, though if this is going to be powerful enough to play in a community hall and also if I can connect a head-michrophone to it as well. Can anybody give me any guidance on these matters, please.

    Well, it really depends on the power (wattage) of the speaker system that you intend to connect the player to, and also how big the area is that you want to fill with sound. I can't guarantee that your potable sound system will be sufficient for the task. It maybe wise to use a bigger stereo system (with a line-in input) so that you can plug players output into the amplifier.
    I used my player in a large hall awhile back and used a separate amplifier and speakers, this did the trick but if the area is rather large and then when full I would recommend that you use something with a bit more power (25 Watts at least)
    using a headphone splitter, available from most good Hi-Fi stores you can plug in you stereo and headphones too so you can monitor the sound, if you want to speak in to a microphone then you'll need a separate connection to your stereo.
    Hope that this is of some help to you.

  • I need to know the right tools and java technology

    Please help,I need to know the right tools and java technology to support what I need.
    I had background programming in Assembly,C++,Visual Basic,SAP/ABAP 4.
    All I can say, programming is about logic, now we are very helped building program using objects.
    I'm very interest to SAP tech, where all screens, programs, reports are resides on tables, this is the real dynamic!
    CUrrently I'm eager to do the same technic with java. I'm new to java....
    What I know the J2EE is the core for me to start is it right? I was very interest with the Client-Server Tech. How can I impelemet this with Java?
    I'm a bit confuse with so many java solutions. There is Java Applets, Swing, Java AWT, JavaBeans, etc...
    I don't know what is the best if I want my Presentation/Client Application will run within browser (not standard html, using like windows gui). What should I do to make business logic objects, how to invoke it within the gui. how to make installation package whenever clients connect to the http server.
    if you have a pointer to do it please let me know.... I'm very appreciate all your response...
    Best regards,
    Lucky Pangemanan

    I'd say - don't get carried away with the heavyweight frameworks. Don't use EJB if Hibernate and/or Tomcat will do the job. There's a danger of winding up using a bulldozer to crack a wallnut.
    What people mean by "J2EE" varies a fair bit.
    Start with Tomcat, which has the virtue of being free. Try some JSPs and servlets.
    Use Applets to do client side presentation only if you must; Applets create an installation overhead on end-users, and some of them can't cope, while others may not have the necessary installation permissions on their office machines. They are pretty rarely needed, IMNSHO, most client-side behaviour is better handled with html and JavaScript.

  • I have suddenly got the following message An (SMTP) error occurred while sending mail. The server responded: Requested action aborted: This mail account has se

    Having been on Thunderbird for some years I have suddenly got the following message when trying to send mail.
    An (SMTP) error occurred while sending mail. The server responded: Requested action aborted: This mail account has sent too many messages in a short amount of time. Please try later..
    I have checked the SMTP server settings in tools, account settings and they are as they have always been. Is there something I have missed?

    Sending through web mail is totally irrelevant to using an SMTP server. The message even says it is from the server. Why do you think this is a Thunderbird problem.
    The provider has put in place measures to keep people from spamming other email recipients using thier SMTP server. You have seen the result of those measures.

  • Process triggered by file upload - is GP the right tool?

    Hello All,
    I have a process I need to model that starts with a file upload from the user, followed by some manipulation of the file by some web services.
    Is GP the right tool for modeling that process?
    After completing the file upload action, how can I access the the uploaded file on the server?
    Do I need to implement the file upload handling with Webdynpor?
    Thanks!
    Yossi

    Yossin,
    Based on your requirement, the GP process would be to use File Input CO followed by Web Service CO (in that order). Consolidate the output param of File Input CO (which is the File Structure) to the input for the Web Service CO (which is also a structure). I dont think you need to save the file to the local drive. The web service should be able to consume the uploaded file (which resides in the process context).
    Thanx,
    Mahesh

  • Adobe AIR for Video Wall project - the right tool?

    I need to decide whether Adobe AIR is the right tool for a Video Wall project. The Video wall would be one of only 4 installations.
    It would need good offline capability.
    The application would play back both canned video as well as twitter feeds.
    The other option is to go all HTML with perhaps the Canvas element to display video, graphics.
    I'm biased towards using Flash, AIR but am open to new ideas.
    What are the pros, cons of each approach?

    Pros of the Adobe route would be a little more control and reliability. You can easily go fullscreen, preload other videos easily in the background and display them on the hardware GPU decoded StageVideo (with the right video card, almost all of them at this point). Twitter feed loading would have some robust error handling to assure it goes smoothly but if you need offline capability you'll need some canned material for the feeds in that situation.
    HTML can go fullscreen but the caveat would be drawing your twitter feed over the video at that point. Because it's fullscreen I don't believe you can have your text over it from a <video> element but you'd need to use <canvas>'s fullscreen and actually mux the text into the video.
    The long haul of Adobe's roadmap clearly states video and games are the future of FP and AIR. I've done tons of kiosks in Flash and AIR, many of which just act as a video wall, attracting people to very large screens. I've had nothing but success doing this. I'd only even approach HTML5 if you have some reason to desire to put this on the web, and even then, Flash is still fine in that situation too.

  • I have done al the right things to set up home sharing for mine and my sons itunes lib but i still not getting the icon showing in the menu for us to select can anyne help?

    Hi I have done all the right things to set up the home sharing, turned it on, aurthorised it with the same details, but we still have not got the home icon in the menu to select. can anyone help?

    If you have iTunes 11 on your computer then you can enable the left-hand sidebar on it via option-command-S on a Mac, control-S on a PC - when connected (and if your computer's iTunes is up-to-date) your iPad should then appear on that sidebar under a 'Devices' heading :
    If you select the iPad on that sidebar you can then use the Movies tab on the right-hand side of the iTunes screen to select and sync that film to your iPad's Videos app.
    Has your iPad been synced to the computer before ? If not then you might find this page for syncing to a new computer useful : https://discussions.apple.com/docs/DOC-3141

  • Is SSAS the right tool to replace SAS Enterprise Guide?

    I am in the process of studying the feasibility of replacing one of our custom built SAS Data Warehouse with Microsoft BI/DW stack.
    I have one specific question that I hope someone here who knows both SSAS and SAS Enterprise Guide can tell me. Feature by feature, in what extent can SSAS replace SAS
    Enterprise Guide?
    To those who has less knowledge of SAS Enterprise Guide, it is a client app that let power users query against database tables/views and apply various statistical analysis
    to the data then output (print/email/save) the result (grid/chart/etc.).
    To name a few of these statistical analysis,
    Under Describe, there are Distribution Analysis; One-Way Frequencies; and Table Analysis;
    Under ANOVA: t Test; One-way ANOVA; Nonparametric One-way ANOVA; linear Models; Mixed Models.
    Under Regression: Linear; Nonlinear; Logistic and Generalized Linear.
    Under Multivariate: Correlations; Canonical Correlation; Principal Components; Factor Analysis…
    And if SSAS along is not enough, what else are needed?
    Thanks!

    Hi Hommer,
    Based on your description, you said that “SAS Enterprise Guide is a client app that let power users query against database tables/views and apply various statistical analysis to the data then output (print/email/save) the result (grid/chart/etc)”. Since
    we are not expert about SAS Enterprise Guide, we cannot give you an exact conclusion. However what we can give you is that there are many adventures of SQL Server Analysis.
    High Performance.
    During cube processing SSAS will pre-calculate and physically stores aggregations of facts. Therefore, when the query is fired SSAS does not have to calculate the outcome from the underlying details but can take the values directly from the stored aggregations.
    High Security
    You can use the security setting to give end-users access to only those parts (slices) of the cube relevant to them.
    Multiple Access/Frontend-tools
    End users can use Microsoft Excel as a power full front-end tool on top of the cube. Besides that the same cube can at the same time be used as a data source for SSRS and SharePoint (KPI-) Web Parts.
    For analytical applications, performance management, or just about anything with a KPI, Analysis Services is the perfect companion for SQL Server. These are complementary databases that do different things well. Using the right tool for the right job will
    make development faster and usability easier.

    Hope this helps.

  • SUBINACL - the right tool for the job?

    Here is the scenario:
    DomainA and DomainB
    Full Trust both ways
    Windows File Share in DomainA. Created a windows server in DomainB. Used Quest Migration Manager to migrate users and groups from DomainA to DomianB, keeping SID history. Xcopied files from DomainA server to DomainB server, keeping the permissions from DomainA. 
    Now, the Trust will be broken and we need to change the permissions from [email protected] to [email protected] Thousands of shares and permissions, so can't do manually. So far I have tried SUBINACL in the following context:
    Subinacl /noverbose /output=e:\ntfs_perms.txt /subdirectories e:\Share
    and then
    Subinacl /playfile e:\ntfs_perms.txt
    This changed some of the permissions to DomainB, but removed a lot of permissions.
    Is this the right tool to use for this? Is this the right syntax for this scenario?
    Thanks!
    Mike

    Hi,
    Sorry for the delay reply.
    It seems like you have  enabled the SID history.
    Based on my experience, after we completing the migration, sIDHistory should be removed from migrated principals to minimize management complexity. Microsoft has provided a sample script and
    Powershell command to remove SIDHistory.
    So, please first confirm if the migration process completed or not, then plan to remove the SIDhistory.
    How To Remove SID History With PowerShell
    http://blogs.technet.com/b/ashleymcglone/archive/2011/11/23/how-to-remove-sid-history-with-powershell.aspx
    Before we do this, please backup the system state to making any important change to avoid any risk.  After clearing the SID history, please try to run the subinacl command to check if it
    works.
    Regards.

  • What's the right tool to use to migrate forms modules.?

    Hi.
    I'm in doubt deciding which might be the right tool to use to migrate forms modules from 6i to 10g.
    The obvious choice seems to be Forms Migration Assistant. However I found Metalink Note: 201344.1 which clearly states :
    "We recommend to use ifcmp90 as there may arise some issues due to the migration assistant ifplsqlconv90. ifcmp90 upgrades the 6i fmb to 9i fmb whereas ifplsqlconv90 upgrades obsolete plsql , such as built-ins like set_alert_property. So it is advisable to use the ifcmp90 instead"
    I have a newer version of FMA and i've done some test and it compiles and upgrades forms modules, but does not generate fmx files. So i conclude one should user FMA first and later generate fmx files either one by one or batch compile.
    Please any comments are welcome ....!

    Hi,
    correct. You use FMA first and then compile the FMX files. You can also use the Forms builder environment to perform the migration, but FMA is more convenient to use.

  • I have purchased a in app purchase of a 'gcsepod' for my little brother however the purchase does not come up in the app and requests me to buy another. How do i solve this? I have also got the receipt for this purchase.

    I'm not sure I can make sense of this but without asking too many questions, you can resolve your question by contacting iTunes direct.
    Apple - Support - iTunes - Contact Us
    But they will be wondering about the reference to hacking and you feeling bad about getting something for free.
    Best step in my view is to make sure you don't get similarly involved in future.  You must know roughly what you were doing.   Then writie it off to a not to be repeated experience.

  • Icons in the addon bar have moved from the right hand corner to the left

    Hi everybody,
    I've recently updated to the most current Firefox 4b10. I'm currently using the addon bar on the bottom that holds several addon-related icons (like firebug etc.). Those do still work, but for some reason they have moved from the right-hand corner of the addon-bar (where they have always been) to the left side for no apparent reason.
    I know it's kind of a little issue, but it is really disturbing since I keep looking in the wrong corner after having the icons there for so many years. Is there any way I can revert that?
    Thanks!

    I have been trying to move a 1 hour movie from my Mac to my iPad without success. I know I have clicked all the right boxes but iTunes is not cooperating.??

    Possibly.
    You could test that by dropping a largish image into a test Pages document and duplicating it until your document won't send.
    Some eMail clients have ceiling levels for file sizes, as do some receiving servers.
    Also test to see if you can simply export your file to pdf, in which case it will be retained on your iPad. That would be a first step.
