Please help! Why are other people on my Network?

So, today I noticed that there were two other users in my Network "folder". I can't get rid of them or even open them, because I'm not authorized. Which is more than a little disconcerting. So what does this mean? Am I getting worked up over nothing? Is somebody using my internet? If so, how can I get rid of them? I feel really uncomfratable with having files on my computer (that only I use) that I don't have access to. Any info would be more than helpfull to this computer illiterate.

Hi Jerkzilla,
Welcome to the forum.
First, ensure that you have File Sharing switched off. You can do this by firing up System Preferences, clicking on the Sharing icon and (within the Service tab) ensuring that Personal File Sharing is not ticked.
If other users on the same network as you have Sharing enabled, you will still be able to see them but they will not be able to see you.
On a side note, when you look in your Network folder you will always see 2 other volumes - Library and and Servers. When you click on Servers it takes you to your starup volume. Are these the 2 that you are seeing?

  • Please Help - why are pics not in focus and sharp?

    I have a 24-70mm f/2.8L lens and am finding that it is not as sharp as i'd expect.  I'm sure it's me and not the lens so hoping someone can help me understand what i'm doing or not doing correctly.
    I'm attaching a picture as an example...hand held...here are the settings:
    EF24-70mm f/2.8L II USM
    59.0mm
    1/640 sec;   f/2.8;   ISO 400
    Shutter priority;   Spot metering
    shot with 70D
    when you zoom into the tree it is cleary not in focus/sharp ;(
    I've tried at differen shutter speeds but still having the same issue... going to try different apertures next...

    next considered a pic with text to really see what's up cropped image to post... this was taken 10feet away from the text - text is on a piece of paper that is 4x4... outside since that is the best light right now - overcast and about an hour before sun set.... shot in M, set the shutter speed an aperture, and use Auto for ISO.  I usually only shoot in Tv or Av so maybe this wasn't a good test for how i use it but wanted to see what would happen...

    JDunlop,
    thanks for your quick reply to my java.sun.com forum posting! i just got back from vacation, so i didn't get a chance to try your method til now. i pulled your email address off the website to update you on my problem playing an avi file in JMStudio (JMF).
    as per your instructions, i downloaded the divx player at www.divx.com and tried to play the avi file. this is the error the divx player gives:
    Divx Player 2.1
    The file contains unknown video data
    The file contains the following type of data:
    Video data: FOURCC code "MP42"
    You may need to install a new video codec on your computer to watch this video
    Some quick questions:
    1. Where could I find the "MP42" codec to play my avi file in JMStudio (JMF)? Does java.sun.com have video codecs?
    2. You mentioned in your posting "If you don't have the one that was used in the encoding, your out of luck." Does this mean that I need to know how the avi file was originally coded and have the original codec to decode (play) it?
    Thanks,
    lac410
    P.S. If you need more Duke Dollars for your help, I'd be happy to award them to you.

    Author: JDunlop Jun 5, 2003 5:00 AM
    sounds to me like you are missing a video codecs. If you don't have the one that was used in the encoding, your out of luck. Download the player from divx.com, it will tell you which codecs the video needs (if it won't play). You can then search the net for that particular codecs.

  • Who are these other people on my network?

    Hello all,
    I wonder if you can help. I'm a home office user.
    I've had my iMac for around six months, but only recently bothered clicking on "Network" in my HD. I found a dozen other users sharing the same network. The number of users varies during the day - it can be up to twenty or so, or as few as ten.
    If I double click on the other users, I get an AFP connection status prompt asking if I want to connect as a Guest or a Registered User. I don't want to go any further, obviously, as I don't want to connect my machine to a stranger's.
    I can't delete other users from my network. I looked one or two of them up in the telephone directory, and they live nearby. Not in the same street, though in the same neighbourhood.
    I understand that ISPs use local loops for high-speed users. However, I didn't expect to see them on my Mac network - or be prompted to connect with them (and, presumably, have them be prompted to connect to my iMac).
    I expect this is an internet service provider problem, and I will contact my ISP helpline once I have heard from you guys whether or not this is a common occurence. I'm in France, and according to yesterday's newspaper a local MP has described calling my ISP's helpline as "a Kafkaesque experience"; a sentiment I fully understand - which is why I'm putting it off until I have as much information as possible.
    Thanks in advance.
    iMac G5   Mac OS X (10.4.4)  

    In the US, broadband companies learned early on that they needed to filter out traffic between nodes. When broadband users here click Network, they will not see their neighbors' computers.
    If you are connected wirelessly, however, you may be seeing other people on your network if you haven't locked it down.
    If you're not using a wireless connection, and you're worried about security I would suggest activating the OS X firewall, creating a fairly complex password on your computer, and turning off file sharing. This is about as safe as you can reasonably get without 3rd party software/hardware.
    The fact that you are seeing other computers just means that the Mac is aware of them, not that they're doing anything malicious. You can't "delete" them or kick them off because you're all on the same network.
    I'm surprised your ISP hasn't filtered out this kind of traffice from node to node.

  • Why do other people get my messages that I send to a specific person

    Why do other people get my messages that I send to a specific person

    They may have all signed into the same ID for iMessage when they updated their devices.  To fix this you have a couple of choices:
    On all but one of the devices go to Settings>Messages>Send & Receive, tap the ID, sign out, then sign back in with a different ID (so each person's devices are using a separate ID for iMessage).  Note: you can still share the same ID for purchasing in Settings>iTunes & App Stores; or
    On all of the devices go to Settings>Messages>Send & Receive and uncheck the email address(es) shown under "You can be reached by iMessage at".  Also uncheck anyone else's phone number, if present.
    I you are sharing the same ID for FaceTime you may end up getting each other's FaceTime calls too.  To prevent this, go to Settings>FaceTime, tap the ID, sign out, then sign back in with a different ID (so each person's devices are using a different ID for FaceTime too).

  • HT201407 Are other people having difficulty having AT&T switch service to the new phone?

    Are other people having dificulty with AT&T switching their service over to the new iPhone 5?

    We got two new Iphone 5's yesterday.  Mine was set up with no problems but my husbands got set up but won't activate...says no service. spent 2 hours on with att tech support Friday night and went to the store today. Its been over 24 hours now and it is still not working.  Worst part--it also deactivated his iphone 4 so he has no phone now!!!  We have reset the network and soft and hard booted it over 100 times now.  This is crazy!  ATT is sending me to apple tomorrow to get it fixed but that is going to be 48 hours with no service at all. Epic fail aT&T!

  • Sept 4, 2014 My iPhone is not connecting to the Hotmail servers. My other email accounts work on it but all the hotmail one comes up with is "The connection to the server failed". Are other people experiencing the same issues?

    Sept 4, 2014 My iPhone is not connecting to the Hotmail servers. Hotmail comes up with "The connection to the server failed". Are other people experiencing the same issues?  From: gnof51

    If your Hotmail account worked previously and it suddenly stopped and gave you that message, then it is likely a problem at th Hotmail end. Did you check the Hotmail website or contact Hotmail directly to see if they are experiencing problems?

    Have you attempted to reset the SMC? That would be the first step. Hold the left control, option, shift key and the power button for about 5 seconds and release. Then try to reboot. Might as well reset the PRAM as well. Hold command, option, P, R on start up until the machine restarts. If that doesnt' have any affect we'll have to dig deeper into a potential hardware failure.
    If this method doesn't work, check the webcam that will tell the problem is on the iSight & WiFi cable. If your webcam is ok, then it'll be the WiFi card problem. Hope it can help ;-)

  • Finding other people on uni network

    Hi
    I'm pretty new to mac but have my new leopard mac. Im at my uni and can see that there are a lot other people using mac books. With my windows machine i could see the other people in my network and share files with them, but how do I do it with the Macbook/Leopard? I have heard something about Bonjour.
    Thanks in advance..
    /Robin

    At my uni (last time I checked was a few months ago, before Leopard), computers sharing iTunes music with Bonjour would just show up automatically in the "shared" list over the network, so I assume that with the new Finder all Bonjour computers would show up in Finder's shared list. (My home Macs share using Bonjour, and they both just show up in the Finder sidebar). Of course you would need permission to access their shared folders (i.e. their username and password). I believe you also need to turn on "File Sharing" in the Sharing pane of System Preferences.

  • Urgent, please help. why the ListSelectionListener() called twice?

    I had two JList, and every time, I click value in list1, it will call the ListSelectionListener() twice, and when I click on value in List2, it called the list2 actionListener twice also, I don't know why?
    Please help.
    The part of the code list below:
    jList1 = new JList(words1);
    JScrollPane scrollPane1 = new JScrollPane(jList1); jList1.setBackground(Color.lightGray);
    jList1.setBorder(BorderFactory.createLoweredBevelBorder());
    jList1.addListSelectionListener(new javax.swing.event.ListSelectionListener() {
    public void valueChanged(ListSelectionEvent e) {
         jList1_valueChanged(e){
    /* add Column_Name to the jList2*/
    JScrollPane scrollPane2 = new JScrollPane(jList2);
    jList2.setBackground(Color.lightGray);
    jList2.setBorder(BorderFactory.createLoweredBevelBorder());
    jList2.addListSelectionListener(new javax.swing.event.ListSelectionListener() {
    public void valueChanged(ListSelectionEvent e) {
    jList2_valueChanged(e);
    void jList1_valueChanged(ListSelectionEvent evt)
    void jList2_valueChanged(ListSelectionEvent evt)
    {     }

    You can call ListSelectionEvent.getValueIsChanging() to find out if the selection is in progress or if has been finished. You will get an event both when the user starts the selection (presses the button) and when he/she finishes it (lets go of the betton).
