Applet Permission Network Problem

Hi,
I have done alot of reading up on applets, to be honest Im more confused when I started!
Basically, here is the scenario:
I have a single java applet, which is a gui that takes some input and then fires it off (via UDP sock connection) to another machine on the same network, this works fine when using appletviewer and granting certain permissions.
But when I try and run it as an applet in a normal browser window it does not work, obviously because I am not "granting" permissions like in the appletviewer.
To be honest I dont want to have to start signing applets and certificates etc, this is not going to be a distributed app, so its for inhouse use it doesnt need to access the users local filesystem, so is there any way of doing this successfully, without all of the above and converting it to an application.
Thanks in advance,
Foobarr

Jsalonen: I dont think it is as easy as that, I have
tried various steps like mentioned, how do I embed the
applet so it knows to look for the cert etc??
In the simplest case you don't even need to provide a certificate, just make a signed .jar file with the jarsigner tool and write a normal <applet> tag:
<applet code="MyMainAppletClass" archive="signed.jar" width="xxx" height="yyy">
</applet>

  • Nm-applet permission problem

    I am trying to use nm-applet under Awesome on my netbook, before I was just using cnetworkmanager but after the last update to NetworkManager cnetworkmanager is now broken.  Wired connections work fine but when I try to connect to a wireless AP I see this error in xterm:
    ** (nm-applet:5116): WARNING**: Failed to add/activate connection: (32) Insufficient privileges
    I have version 0.8.999 of nm-applet and network manager installed, what kind of privileges does it need that knetworkmanager (also have KDE installed on the side) and cnetworkmanager doesn't?

  • LaCie MiniHD connect network problem

    I have a LaCie MiniHD connect in my local network. Did everything LaCie told me to do so I could write to the USB attached LaCie drive.
    Formatted the drive in OS X EXtended but not journalized.
    Tried to connect via smb://MiniHD.smb.tcp.local and the network told me to enter my ID and Password, I don't know why.
    So I brought back the disk drive to my mac and changed the whole drive permission to read and write for everyone.
    Brought back the drive to my TV and now I could transfer anything from my mac to the drive.
    I was glad of that, but having shut down the drive and the MiniHD connect, when I opened it again to transfer something from my mac to the drive, I still got the same problem again with the same message.
    "One or more elements cannot be copied to "LaCie_750" because you don't have the permission to read. Do you want to copy the elements you are authorized to read."
    I suspect the software on the Lacie MiniHD connect to block OS X when it initialises the drive on startup.
    In particular I see a folder named _HF2VN~W appearing in the root level of the drive.
    Can any one help me with thi samba network problem on Mac OX 10.6.5?

    I have since had a reply from LaCie to say that this issue has been identified and is being worked on - however I'm afraid that I don't have any timeline for when this will be fixed.

  • Testing  HTTP URL that causes a network problem

    Hi all,
    I'm developping an applet for multiple unlimited files downloading using HttpConnection .
    i want to implement the following feature :
    In the case of an error occurring due to network problems during file download; the applet must be able to reconnect and resume the data transfer without downloading the entire file(s).
    well i need to test this feature ; so i'm looking for some HTTP URL that can cause network probs so i can catch the error and retry connection etc...
    can someone point me where to find such HTTP files for my test ?
    thanks.

    >
    I can do this with FTP since it has commands to do
    this but I don't know of any using HTTP unless one
    uses a Servlet (or some other agent on the server) to
    process a download request for a file starting at
    some offset.
    Actually i did it only using HttpConnetion class and inputstream using some work arounds to keep track of the offset during download (actually i'm saving the offset to a temporary proprieties file that i'm reading again to get specific offset and resuming the download from last point)
    That is one way. You could also use an HTTP 'tunnel'
    that forwards all requests to an HTTP server but
    within the 'tunnel' you could at random close the
    connection.I will go for throwing exception manually ; but i'm curious to know how an HTTP tunnel works.
    thanks.

  • Software Update can't check for updates because of a network problem....after firmware update

    I just bought a MBP w/Lion (10.7.4) and ran software update.  The first two items I updated were firmware for SMC (ver 1.5) and EFI (ver 2.7) and now my MBP says: "Software Update can't check for updates because of a network problem."  However, I can connect to the Internet to surf the web just fine.  This is the only update I've made.  Can firmware be uninstalled?  If I reverted to the image on my external drive that I did with CCC prior to the update, would that fix it?

    Hi! i hope i'm able to explain what i worked out and what worked for me. I had the same message coming up "no internet connection, run network/internet diagnosis" etc etc. Internet connection was fine. What i finally did:
    Open airport, check internet, internet options ; with me, IPv6 was set as  this (the letters are in german order and not in a english order, sorry...):
    In system prefs, network/TCP/IP  IPv6 was set to "automatic":
    I did change the settings in Airport back to "Link Local" and Software Update worked immediately normal whithout restarting the computer.
    No idea what changed the settings; however i did run permission repairs beforehand with no connection to any problems, just as a normal kind of 'maintenance routine'.
    Hope this helps others, it worked for me.
    Cheers

  • Odd Network Problem

    Hi,
    I have a strange network problem, can anybody help?
    Basic configuration
    I have three networks 10.190.0.0, 10.192.0.0 and 10.193.0.0 joined by a single server running Solaris 11 B64a with a dual port intel card and onboard intel card (e1000g0/g1/g2) each port is plugged into the gigabit port of a seperate Dell powerconnect switch.
    they have ip addresses of 10.190.0.2, 10.192.0.1 and 10.193.0.1
    The problem. I have connected from a remote machine through a solaris router machine on the 10.190.0.0 network to a computer on the 10.192.0.0 network (Beyond a switch).
    The terminal works fine!
    if I ping the 10.190.0.1 which is the other router beyond the box with the three network interfaces packets are not seen by the pinging box. However, if I snoop the interface on the three interface router I see both the ICMP echo requests and replies.
    After a considerable length of time 10-30 seconds, a load of the packets suddenly appear on the pinging machine and then continue normally.
    I would like to understand:
    a) where were the packets during the time between the snoop seeing them leave and them arriving at the destination?
    b) why does the terminal not suffer any delays?
    We are suffering with a lot of strange network issues at this new site and I am trying to figure out if its the new dell switches, the solaris network stack or something else entirely!
    Anybody got any idea whats going on?
    Please Help I am baffled.

    It may just be the pinging machine has received the packets, but it will not display them on screen until it has found a name for the remote IP address (or until it times out waiting for one).
    Do you get the same behavior with 'ping -n' ?

  • Mobile network problem in my lumia 520

    Once network gone, I have to Restart it then again mobile network come.calling proble occurs many times even network is dispayed. Network problem sshould be rectify.

    Hi mbkrish,
    Do you experience the network issue regardless of your area? Aside from calling, are the other network services working fine like SMS messaging and mobile data connection? Is this for a Lumia 520 as well? If so, I hope you're using a standard microSIM and not a cut one as this is what the phone is designed to use.
    BTW, the reset that the Nokia Care Center recommended is the one under Settings > about, is that right? After the reset, have you checked if the system apps are updated? Go to Settings > swipe to applications > store > check for updates. 
    Let us know how it will go.

  • Time Machine and Time Capsule - Failing with Network Problem

    My problems with TM/TC have been ongoing for a couple of months now and I am going round in circles - need help.
    This is the second post I have made, the first got lost in people suggesting the obvious - so I will try to be a little more specific if I can.
    I will detail the current state first - i.e. where I am now - after I will list what I have done so far to get to this point.
    Currently, my iMac (intel) is directly connected by Ethernet 1GB to the Time Capsule. The TC is then connected to a Netgear router which in turn is connected to Internet.
    I have no network problems at all - internet connection is fine. the Netgear Router has the latest firmware version and is working fine. The porblems i have are nothing to do with this.
    The time Capsule is in Bridge mode and getting a reserved dhcp IP address from the Netgear router.
    The Time Capsule has been fully reset - i.e. power cable out, hold the reset button, plug in power cable (spark, spark), hold reset button, fast blink for 20 seconds or so, light goes out, release button.
    I have re-applied the latest Time Capsule firmware.
    I have renamed the disk on the Time Capsule.
    I have renamed my iMac and deleted all the time capsule entries from Keychain.
    I have re-installed Mac OSX and re-updated to the latest 10.5.6 release.
    At the moment I have kicked off a backup with a lot of large files - like music folder, video folder etc excluded. I also have parallels and have excluded the disk image. I have 1 other 50GB disk image which is also excluded.
    I am expecting the first initial backup will complete successfully.
    I will then remove music and video from exclusions and allow them to backup. I am expecting this will complete no problem. (I do this because the upcoming problem will happen if I move away from the machine - and I dont want to sit there for 2 days).
    So up to this point TM and TC have performed flawlessly. The issue that follows started happening before the 10.5.6 update after backing up with no issues for months. At this point I will be able to use TM to browse the backup and restore files. I will be able to mount the sparse bundle and browse files. Spotlight reports no issues and indexes quickly.
    If I leave my machine after a successful backup and the hourly update kicks in it will fail with 'A Network problem' basically saying the backup has filed because of a network problem, but is not any more specific, logs show far too much to put the whole thing here, but the following is an excerpt

    It goes on and on and is repeated every hour. For each one I get an error message on screen saying backup failed due to a network error. However I have tried a manual download over the same period set at an extremely slow rate so that it was downloading during this time and it showed no errors. I.e. the network connection from imac, through TC to netgear and out to internet - and monitored this while time machine showed these errors (i.e. at the same time) and this showed no connection problems at all and completed succesfully.
    I know TM uses an internal address to do backups, but uses the same cable and network card to get the job done. I am simply removing the cable as a source of issue although I have also replaced this making no difference.
    Applecare are involved and have so far been sent 2 sets of logs and so far have not been able to find the cause. New TC is on its way to try that, although they think it is something on the imac that is causing this.
    Sleep mode is turned off although screen sleep is on. The tick is not in the box for putting hard drives to sleep whenever possible.
    Now, after this has happened, and back at the machine. I restart both imac and TC. Try running a backup, spotlight starts to re-index - i.e. will mount the backup volume and start the index process, gets to about 90% then fails - again excerpts from log

    Am I the only one having these problems? any help from anybody please...

    Got the same problem with a 3 months old TC.
    The replacement TC, does it work now flawless?

  • I try signing into iMessage and it takes about 45-50 seconds to do. When that happens it tells me there is a network problem. I am positive I don't have a network problem and I need help on this problem please??

    I try to sign in and it just takes forever to do I try and try and do it over and over and it brings me the same results. Created a new Apple ID and when I did it still tells me there is a network problem. But the thing is I am still able to use the Internet I need help?? And it does the exact same thing for FaceTime so I don't know what to do??

    I am having a networking problem on one of the volumes of my multi-volumed, three-Mac local area network, and I need a networking guru to identify the specific software file(s), application(s), or system configuration that is the cause of the problem. I have already spent several hours checking and re-checking the various hardware and system preference settings involved, and I have narrowed the problem down to a software corruption issue and/or system configuration issue on one volume.
    I now need someone to identify specifically what the nature of the problem is, and how to eliminate it. I am not looking for a sledgehammer solution that says I should re-install all of the Mac OS X software on the problem volume. That may be held in reserve as a last resort. I'm looking for a more elegant approach, one that points out the specific corrupt files to remove without disturbing everything else.
    Here's some background to set the context. I have a MacBook Pro laptop; a PowerMac iMac G5; and a PowerMac G4 hooked up in a network. All are running Leopard 10.5.8. All have file sharing and screen sharing enabled. Besides being able to connect to each other using registered users, my goal here is for each of the Macs to be able to share the screen of the others upon my demand. Since each of the 3 Macs can theoretically share the screens of the other 2, that makes a total of six possible connections. Five succeed; one does not. That's the problem. I am trying to determine why the iMac G5 cannot share the screen of the MacBook Pro.
    The iMac G5 has no problem sharing the screen of the PowerMac G4. That connection is fast and immediate. But, every time that I hit the Share Screen button on the iMac G5 to try to connect to the MacBook Pro, I get a window with the blue barber pole spinning for two or three minutes as it is allegedly "Connecting to Mac Book Pro," followed by a window with a headline telling me that "Connection Failed to MacBook Pro." The text within that window goes on to say: "Please make sure that Screen Sharing (in the Sharing section of System Preferences) is enabled on the computer to which you are attempting to connect. Also make sure that your network connection is working properly."
    Well, as I indicated, the PowerMac G4 has no problem sharing the screen of the MacBook Pro, so the Screen Sharing settings on the laptop are correct; and the iMac G5 can share the screen of the PowerMac G4, so its network connection is working properly in that regard. It is only in regards to sharing the screen of the MacBook Pro that the iMac G5 is not working properly.
    The reason why I say that the issue must be unique to the one volume in question, let's call it "iMacG5 Music," is that another Leopard volume on the same computer has no problem whatsoever in sharing the screen of the MacBook Pro. Whenever I boot up in that volume, let's call it "iMacG5 JMB," it makes a network connection with a registered user name immediately, and it is able to share the screen of the MacBook Pro within a second of my issuing the command. In sharp contrast to the success of the iMacG5 JMB volume, the iMacG5 Music is unacceptably slow (several minutes slow!) in making a network connection with the MacBook Pro, and it always fails to share the screen of the MacBook Pro, preferring instead to take about three minutes to attempt the connection, before announcing its failure.
    Since the iMacG5 Music volume makes an immediate network connection to the PowerMac G4, as well as sharing the screen of the PowerMac G4 the moment I ask it to, I have concluded that the hardware of the iMac G5 is just fine. The problem seems confined to the system software and/or associated networking files that are unique to the iMacG5 Music volume. I just don't know what those files could be, or where the problem lies, so I've issued this call for help.
    Let me add one more little twist to this puzzle which baffles me even more. I use external LaCie Firewire drives as clone backups of my Macs. As part of my trouble-shooting process, I booted up from the cloned versions of the iMacG5 JMB volume and the iMacG5 Music volume. What I learned surprised me!
    The iMacG5 JMB clone worked just fine in making a fast network connection to the MacBook Pro, as well as sharing the screen of the MacBook Pro. I expected that. What I did not expect was that the iMacG5 Music clone was also able to make a fast network to the MacBook Pro, as well as share its screen!
    Yes, that's right. It's weird! Screen sharing works OK when I start-up from the clone of the iMacG5 Music volume, but it does not succeed when I boot up on the source itself! I was surprised to find that out, but I'm glad I did.
    (Over the past few days since I executed the last clone, I did use Drive Genius to de-frag the source volume, and maybe that has contributed to the problem I am now encountering. But it's hard to say, since nothing else seems to be amiss.)
    One solution, I suppose, would be to sync the clone back to the source. But, before I do that, I'm just wondering if anyone has a clue as to the nature of this problem on the source volume and what I might do to remedy it—short of re-installing the system software or restoring from the clone. Anyone have any insight to this problem?

    CORRECTION #2:
    Ignore the previous "CORRECTION" post.
    Oops, excuse me, I wrote that sentence correctly the first time.
    I was trying to point out that the ability of the iMac G5 computer to connect quickly and effectively to the PowerMac G4 when booted up into the iMacG5 Music volume was an indication (to me, anyway) that there is nothing wrong with the computer's hardware, nor its network connection ability, but that the problem lay somewhere in the files/settings used to connect to the MacBook Pro, which it cannot accomplish.
    This is what happens when I get engrossed in one of these technical morasses and it ***** me into its vortex all through the night... time for bed.

  • Time Machine couldn't complete the backup due to a network problem

    Firstly apologies for the long post, I've been bottling these problems up and could now use some expert advice.
    I have a MacPro (10.6.3) with four internal drives (320GB system/apps. + 3x 750GB data, images etc) and a MacBook Pro (10.6.6) with a 320GB internal. With so much accumulated data (Mac user since SE FDHD) I wanted a reliable means to backup all my projects, books, papers, research, images etc. I had several bad experiences using Iomega drives (Ultramax and Storcentre) which were not very Mac compatible and shifted over to a 10TB LaCie 5Big Network 2 which is promoted as Time Machine compatible. Set up Time Machine (with a few hiccups) in Sept 2010 and it ran perfectly, backing up both main computers until March 2011. I have now experienced a string of problems backing up the MacPro, some of which have been resolved speaking to people, some by checking forums and some by using my own noddle to figure it out. The latest error message I am getting is "Time Machine couldn't complete the backup due to a network problem. Make sure your computer and the backup disc are on the same network, and that the backup disc is turned on. Then try again to back up."
    The circumstances of this are as follows: TM seems to be trying to completely back up everything already backed up from previous months so I am using the "exclude" option to do this in manageable chunks (5.54TB of 7.99TB is available so there is a lot of stuff on there, hence my reticence to erase and start again). I started a backup last night which said it was 242GB and when I came back hours later (I estimate 30GB and hour or 500MB a minute) it has failed with the error message above. I asked it to back up again and it said it now had 191GB to backup, at the next failure it was 142GB, dropping by approx 50GB a time (if there a maximum it can manage in one go?), the next time it was starting again with 242GB.
    I checked the disc it was backing up to, discovered it was now selecting Public-1, re-selected Public which houses the macpro.sparsebundle, dropped the backup size (Options) to 73GB and set it off again and it is backing up as I write. I am hoping it will complete and permit another chunk to be backup but the fact it looses network connection (seemingly) or has a maximum backup in one go, is annoying because it means you cannot leave it overnight and trust it to do the backups.
    The other problem seems to be a shut down by LaCie 5Big because several times (and once this morning) I have had this message "The file server "LaCie 5Big" has closed down, followed by a complete Lacie shut down and auto-reboot with all lights and whistles. Lacie think this could be a power supply problem and say they are sending me another power brick. They also say they do not support Time Machine (they should check their own literature) and suggest I use LaCie 5Big for 'drag and drop' backup. If I wanted to do that I could pick up a cheap and nasty HD from PCWorld, not this high end 10TB drive which cost over £1,000 !
    For a while y'day I could not even find the Lacie on the network but after changing the ethernet cable from Lacie to router (Linksys) it miraculously re-appeared so that problem may have been the original Lacie blue ethernet cable had developed a fault. Checking cables is an oft-overlooked option.
    A catalogue of errors, some solved, others still all pervading, so any words from the wise would be gratefully accepted.

    I verified the macpro.sparsebundle and Time Machine backups in Disk Utility and it said both appeared to be Okay in green type. So that did not solve the issue. I did a Disk Utility repair a day or so again (despite Verify saying everything was fine) and said there was nothing to repair. I suspect two problems, the power brick may be faulty producing intermittent power and maybe causing the drive to close down (hopefully Lacie will send me a replacement to try) and second, I am thinking the network connection is getting dropped causing crashed backups without the Lacie shutdown/reboot sequence. The 73GB back up failed, I started it again at 54GB and it failed again, just started it again at 45GB - this is no way to progress!
    Perhaps the relatively new (last year) Linksys router is the problem, I find my MBP says AirPort is active but it fails to appear in Go>Server unless I switch it off and on again and perhaps a similar problem drops the connnection to the Lacie.

  • Networking problem after a zone is created and installed

    Hi all,
    I've got a networking problem after a zone was created and installed on a Solaris 10 box. The box was configured with two NICs, one (e1000g0) with a public IP address, the other one (e1000g1) with a private IP address and connected to a local switch. All worked fine so far.
    Then I created a local zone with shared networking (e1000g1). The zone has a private IP address which is in the same subnet as e1000g1 on the global zone. After some time, I noticed that I could not access (ssh, ping) the global zone. Then after some time, the global zone became available. The problem happened quite frequently.
    Also I observed that: 1) When the global zone was unavailable from outside, it was available (ssh, ping) from another box within the same subnet (e1000g0); 2) If I shutdown e1000g1, the problem was gone.
    Any idea what caused this problem?
    Many thanks,
    Xiaobo
