Terminal Keyboard features for a Linux based Server System

Hi Forum,
there are some highlighted characters within terminal functions at a linux server (redhat or suse or ...) With Putty or a linux connection I get the special keys that are highlighted to work with the "alt" key pressed. Example is the terminal button "ok" with the "o" highlighted. If I press "alt"+"o" it would be choosen and the next page will be shown. Is there a way to make this work on a MacOSX Terminal? I had no chance to find anything similar with google. I hope you might find a solution!
Thank you and best regards,

  • Building a simple J2ME chat client (for own J2SE-based server) Threading Qs

    Hi!
    I am making my own simple chat / messenger service to use between a couple of friends over GPRS.
    On the server side i have made a multi threaded TCP server that opens a new thread for each connecting client and stores these socket connections in a hashtable for access to send data between each thread.
    So when a client logs on to the server, the server sends a printwriter message to all other clients informing them of what client connected, and the clients can put the username in its out-database. then the clients can send messages to each others using a simple, self build protocol.
    All connection between clients/server happens over a simple printwriter on in/out streams.
    Problem is: it works perfectly most of the time.... However, sometimes a message is mysteriously lost when transferred from the server to a client. Transfer from client to server works flawlessly. I am thinking that it might have something to do with the client side threading, or slow network transfer casuing a TCP read error.
    Client structure is as following:
    start-> Midlet class -> (press connect to server) -> new Client class (impl runnable) -> new thread(this) -> void run() sets up all connections and writers, waits in a while loop for messages from server and takes action according to message type. -> Button(send) uses output stream to send a message to server.
    Do anyone have any suggestions on what I must consider when making a client that will simultaniously be able to listen for data from server as well as send data to server over 1 socket and slow mobile connection without causing any trouble?
    More info can be provided if necessary.
    Thank you!

    Building a simple J2ME chat client (for own J2SE-based server)a. i would like to say that this is a bl00dy brilliant idea. i mean ~ its been done before but building one yourself is quite thrilling.
    b. are u using java 4 or java 5. ?
    sometimes a message is mysteriously lost when transferred from the server to a client. Transfer from client to server works flawlessly.are you using push registry to recieve incoming connections.
    i recommend using a StreamConnectionNotifier connection instead of just a socket connection. you could send your data (xml/plain text) just like a stream (tcp ofcourse). if you want to know how to use a StreamConnectionNotifier connection, here's how
    try{
    // listen at local port 789
    StreamConnectionNotifier notify = (StreamConnectionNotifier) Connector.open(“http://:789”);
    // infinite loop to get incoming connections
    for(;;)
    StreamConnection stream = notify.acceptandOpen();  // return a stream connection when a connection is made
    InputStrean mystream = stream.openInputStream();
    while(mystream!=-1)
    mystream.read();

  • Trying to view a linux based dvr system on my mac

    Im trying to remote view a linux based dvr system on my mac, I can log into the system, and use the controls, however I cannot view the video on any of the cameras, in windows it requires an active x control installed anyone know what the mac equivalent is?
    Thanks

    ...it requires an active x control installed...
    Simple answer: no.  ActiveX plug-ins are usually Internet Explorer only.  Thus you would not be able to view this on OSX.  You could install Windows on your Mac using Boot Camp or a virtual machine, but that's still viewing using Windows.

  • Integrating Blogging feature for a Java based website

    Hello everyone,
    I am having a requirement for the website I am working on where I need to build the Blog functionality. Our website is built using Java platform. Most of the articles on google were on wordpress which is for PHP based websites. I was wondering if any you are aware of any good softwares/ tools that I can use to create a blogging functionality on our Java based website. Right now am experimenting with NWordpress but I din't find any good documentation on how to use it.
    It would be really great if someone can point me in the right direction. Your help is very much appreciated.

  • Playing .dcr files on linux-based server

    Hi there. So I've got situation like this:
    I would like to present .dcr files on my site (modified
    Coppermine gallery). And it would be great if I could play these
    files with internal player (or sth like this) and not count that my
    visitors have a plugin installed.
    The point is that only about 55% of Windows users can play
    .dcr files (via browser), not even mention Linux users. So I would
    like to let my visitors play in games (.dcr files) without any
    actions from their side.
    Is it possible guys?

    Oops. didn;t mean to hit send ;). No, I really don't think
    this is possible.
    The browser needs to know how to interpret the DCR file (as
    it does a SWF
    file) - hence the need to download the Shockwave or Flash
    plugin in the
    first place.

  • Why do keyboard shortcuts for menu items created in System Preferences appear in Firefox menus but not work?

    Given that Firefox does not obey the System Preferences custom keyboard shortcuts, why does it still display those shortcuts in the menus, thereby incorrectly telling users that they will work?
    This issue was raised 6 months ago, but the only posted answer did not explain why the menus reflect the shortcuts that Firefox doesn't obey.

    Outlines are discussed in a series of articles beginning with Creating an Outline in Chapter 5 of the Pages '09 User Guide. A similar set of articles, beginning with Creating Lists follows immediately.
    Reading through the articles, I don't see any mention of a keyboard shortcut or menu item related to moving an item up or down in the list. A search through Pages '09's menus was also unproductive.
    Apparently this 'essential function' is unsupported in Pages.
    Feature requests should be made through Provide Pages Feedback, found in the Application menu (in Pages, the 'Pages' menu), where they'll go to and be read by Apple. Here you're posting to Pages users, who can help you use existing features, but have no direct influence on missing ones.

  • Crover - generate OS version numbers for Arch Linux

    Arch is a rolling distro, but did you ever wish it still had release numbers? So you could check what "version" you currently have installed, and upgrade to the latest "version" if necessary, with a reasonable delay between versions?
    Of course you didn't. No sensible person would want to attach pseudo-version numbers to a rolling distro.
    https://code.google.com/p/crover/
    https://aur.archlinux.org/packages/crover/
    crover returns a version number for Arch Linux based on time elapsed since the distro's initial release (March 11, 2002). The number format is X.Y, with X being years and Y being subdivisions of the current year. By default, the version number is generated for the current date with a subdivision size of one week.
    As of this writing, the current version is Arch Linux 12.1. In other words, Arch is 12 years and 1 week old.

    Hmm, you could actually make this somewhat more relevant to actual update practices if you wanted. Were I to try to accomplish such a task, I would figure out a way to check and see if all the official repos are up-to-date (or just if all the packages the user has installed are up-to-date with `checkupdates`). Then, take the number of seconds elapsed since Arch's release till the last update (which brought that rig up-to-date).
    Then, you could grab the user's list of currently installed packages with pacman and take a hash of it. And, by concatenating those two figures together, you could get some semblance of a "version" number. For example, mine would be something similar to the following:
    378691200.4c41d609
    Not to mention, with this calculation, it would not be difficult to format the time part of the version in a variety of ways. May be worth thinking about
    All the best,

  • SMD agent for VMW-based SAP systems

    SAP talents:
    We have hard time to configure SMD agents for VMW-based SAP systems.
    We have followed some SAP documents for non-VMW-based SAP systems, but seems that SMD agent cannot
    differentiate the individual system on VMW.
    Our SMD agent has no problem for non-VMW-based systems.
    Thanks!

    Sorry to reply late because we have attempted a lot of  fixes but all failed
    For example, we have QAX, QAY and QAZ on VMW. 
    On Wily Introscope:
    1)  QAZ simply does not show up even we deployed/configured the agents as the procedure specified;
    2) under the node QAX, we see QAY's entry as a sub-entry.
    Does each SAP system need an agent OR only one agent is enough?  We have tried both ways  but
    seems not working properly either way.
    Please help, thanks a lot!

  • Client Based Database System

    I'm trying to come out with a design for a client-based database system. i wanna create at least 20 databases all linked to one main server and i can make updates whenever i want either manually or thru the update table that will update automatically all the other databases.
    each client can look other's information on the server and get access to it as well as clients will get the ability to communicate thru the server or sub-servers within the network.
    im really confused myself how to start this and what will be the ideal shema or design to start off with.
    i d really appreciate any hints guys.
    thanks

    If the goal is disaster recovery, you want to be looking into something like DataGuard to provide a hot standby. Basically, you take archive logs from the primary, copy them to the standby database running in a physically separate data center, and apply the logs to the standby. In the event of a failure on the primary, you simply transition over to the hot standby database. You can configure DataGuard in a variety of modes, including zero data loss (though there will be perforamance and availability implications for this sort of setting).
    I don't understand the second part of your question.
    how are the tables gonna be structured? This will depend entirely on your application. You don't need anything special in your data model to use DataGuard.
    because this is a client based application...so it requires an updatable table or sourceI don't follow this at all.
    can i get some details or a shema that shows how to put these tables togetherNor do I follow this
    let's say we have one main server or source and only two other client applicationsWhat do you mean by "two other client applications"? Do you really mean applications (i.e. a collection of J2EE, .NET, PHP, etc components)? Or are you coming back to a multiple database setup with replication?

  • Can ARD 3 be used for users who want to remote into a windows based server?

    I have a couple users at the company I work at who will need to be able to remote into our Windows Server. These users all have Macs and will have to go about remoting in differently. I have done some research on Apple Remote Desktop but i am unsure if it fits my users needs. If I have someone download and install this software on a mac, will they then be able to remote into a windows based server using an IP address? that is my goal in mind  could get some help on this one I'd appreciate it.
    Thanks,
    - Rich

    I'm referring to what windows can do via Remote Desktop connection.
    You open up the RDC dialog box, enter an external IP address (if working remotely) or a server name if working internally and connect right to the machine. Ideally i want my users to be able to log into our terminal server and be able to use a program remotely. they will have to log on to this server with company credentials. Basically from a mac, connecting up to a Windows Server and remotely logging into it to perform tasks.
    I'm really just trying to find an easy way to do this for my user's with MAC's since it is not as straightforward as in windows. I cannot test anything out at home since i do not own a mac so i come to the community to see if you guys have had the same kind of situation before.
    ARD was the first peice of software that looked like it might fit my needs but if it doesn't is there anything out there? is it for free or for a cost? any help is greatly appreciated. Thanks.

  • Is it possible for a mac to run across a Windows based server such as in a school, and still be able to access all networked folders? I have been told that macs can only read down a certain number of folders

    Is it possible to run a mac on a windows based server? We have a server based on Windows 7 in our school, and our techies are reluctant to let me buy a mac as they say macs can only read a number of folders deep, which would preclude me from accessing shared folders on our servers. Is this true, and is there a way round this? I would eventually like to get a suite of macs, but because all our resources are on the server, I have to be able to access them.
    Thanks for any help,
    Mike

    I have found that both Linux and Mac (unix) are capable of reading "deep" folders while win 32 will have issues, your it people are clearly wrong.  I run a network with both win/mac. And as long as the win servers/pc's that have shares are set to allow apple file sharing in their folder properties.   And the macs are set to allow smb there should absolutely no trouble with you accessing anything across the platforms, heck, from a Mac to a win pc on some occasions you don't even need to include a "domain" name to log on to, and you can create aliases and make your own shortcuts etc... So you don't have to manually connect each time you boot up etc... But that's all personal preferences I suppose.
    All I can tell you is that, I do it on a daily basis managing a small business. So your answer is yes you can.

  • How to Use JNI for linux based C programs

    Hi all,
    I am doing my project in JAVA for my Institute. There is a Central server. All the API's have written in C. The C APIs are Linux based.
    The problem is getting records from the database through API.
    I tried the Java Native Methods. I am able to do that in console with out problem. Since my project is web based I want to fetch the records through the C APIs in JSP. Is it possible? How to do that?
    Please Help me.

    Why can't you use JDBC?
    I tried the Java Native Methods. I am able to do that in console with out problem. Since my project is web based I want to fetch the records through the C APIs in JSP. Is it possible? How to do that?JSP runs in a server. Which is just a big console application. Same as any other.
    Basic process.
    1. Write the JNI
    2. Insure the JNI is in the servers shared library path. This can depend on the user that the server runs under (unlikely to be you.)
    3. Add the java code into the server.
