OS X :: Prevent Internet Access For Computer In Same Network?
Jun 9, 2009
Just wondering if there is anyway to block internet access temporarily.(not on my computer, but I was wondering if I could to some wacky-code stuff and such to prevent access on another computer that is in my network) The reason why I am asking this is because I think there isn't enough bandwidth to go around my house (there are 2 xbox 360s hooked up to live, and 3 computers hooked up). But just wondering if this is possible to do because ever since my step sister came here for the summer, I have been getting dced non-stop.
Ive got a DrayTek Vigor2700 router. The DrayTek router is located in the first floor and is hooked up to the phone line. It creates Wireless network (called "default") for the first floor. On the second floor there is an AirPort Extreme Basestation. Its hooked up to the DrayTek by ethernet and creates a network (called "AirPort Extreme". To the AirPort there is a 500 gb USB drive and a USB printer connected.
1 floor: DrayTek hooked up to the phone line creating a network 2 floor: AirPort Extreme hooked up to the DrayTek via ethernet, creating a new network. Got 500gb USB drive and a USB Printer connected to the AirPort.
AIM: I want to be able to access the USB drive and the printer over internet. I dont have a MobileMe acc, and i dont want to create one. I know it would be much easier if the AirPort would be hooked up to the phone line directly, but Its not possible...
I have had my MacBook for 6 months and it has worked just great with my WiFi network and any other WiFi I have happened to connect it to. This morning, while I was downloading some files, my internet connection died on me. At 1st I thought it was my provider and I usually fix that by restarting my Router. I did that, but nothing happened. I could detect and connect to my WiFi but I had no internet access! My wife's PC and mobile phone connect perfectly well to my WiFi and so does my iPhone!!! My MacBook now only works with Ethernet. Let me add that I have the 13.3" MacBook unibody running the latest Leopard 10.5.8. software upgrades.
I can't use my Facetime as I enter my Apple ID it keeps coming up with "Facetime could not sign in. Please check your network connection and try again." but my network is ok and can access the net. My apple ID works fine with iTunes and Apple TV and my iPad so I am at a loss.
i am trying to hook up a mac mini to a local wireless network (airport express) so that i can access a shared iTunes library but i do not want the mac mini to be able to access the internet (other macs on the network need to be able to access the internet). is there a way to change the settings on the mac mini so that this is possible?
I'm visiting my mom and trying to access the internet via one of her neighbors. He's has ok'd this and gave me his password. In the past, this has worked. But now, my daughter can access internet on her mac, but I cannot. I have both mac right here side by side. One has access, one does not.
In OSX 10.6, I can use "internet sharing" to set up a wireless network, connecting my wifi enabled music player (or Apple TV) to my MacBook Pro via wifi without actually connect my Macbook Pro to the Internet. However with OSX 10.7 Lion, "internet sharing" requires actual connection to the Internet. Is there a way to disable Lion's requirement? All I need is to stream the music files in my Mac via wifi to my music player (Logitech Squeeze Box 3), and I don't always have access to the Internet. Of course an Airport Express or any router would solve the problem, but that means one more device.Â
Or, is there any other method to set up a local wireless network without actual Internet access? I tried "Creat Network...." in Airport but that doesn't work with passive music player (or Apple TV). It seems only work with computer to computer networking.
Is there a way to temporarily disable wireless network access for a specific computer, rather than changing the network password or creating a new network altogether? I'd like to be able to grant the computer access to the network when I want (and control this from the admin computer, without having to change anything on the computer for limited access).
I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?Â

OSX has a rather annoying feature, on many commands it will spin up my external harddrive out of its sleep mode. I have to wait for the harddrive to get up to speed and during that wait i get the spinning beach ball. Its really annoying because it will do that on things totally unrelated to the external like bookmarking a webpage, going into a new tab in safari, switching between programs.
What i would like to to make it so that the external harddrive is only spun up when its actually being used! I dont want to have it going all the time because i value the quietness of my mac, at the moment its pretty much silent apart from when the external harddrive is going or the fans are going flatout.

I'm on mid 2010 Macbook Pro running OS X 10.9.4 and I can't figure out a way to prevent a certain wifi network from becoming known. My college's network requires an in browser sign up every time and once the network becomes known it gives me an SSL error until I remove it from the list of known networks and refresh.
I am in china and im using a proxy to access facebook, youtube and other blocked sites. However i would like to use another browser that isn't affected by IE's internet settings because with the proxy on, browsing local websites just becomes gruelingly slow. I am using mozilla currently because there's an option to not use system proxy. Meanwhile i tried removing the proxy settings in safari not realizing the it shares the same settings with IE therefore if i remove it, it also turns off the proxy connection. i heard safari is great so if there's a work around on this then i'll definitely switch.
this evening, a neighbor's xfinity wireless network kept flashing what appeared to be web pages on my MBPro screen. They weren't attached to any browser I was running.Â
I'd close these pages (ads to join xfinity) but they'd keep coming back. Then I noticed that I'd been booted from my own wireless network, and xfinity was the active network!Â
It feels predatory, this behavior. How can I set up our Macs to prevent this ever happening again? When I join our wifi in our home, I don't want any other signal to elbow in, so to speak.Â
Or, if there's some kind of interruption in our wifi signal, I don't want some other network elbowing in.Â
However it happened, how can I set it up such that, if I didn't authorize a wifi network, it will be prevented from joining me to it?

I have given up on getting home sharing to work properly amongst all my various computers at home on 10.5 and thought I would use an old style brute force method of simply setting up a file share to share my iTunes library. I set up file sharing to use the Guest account and it works fine for all of my other content. I have tried to create shares of the following directories and can only connect as a registered user (Guest user cannot even see these shares):
/Users/<name>/Music
/Users/<name>/Music/iTunes
I have gone into the terminal and looked at the ACLs on the Music directory (e.g ls -alte) and I can't see anything that would block access, but I am not an expert with this type of ACL. The ACL on the Music directory is this:
I have an ACL called 0: group:everyone deny delete on one of my other shares that works fine so this can't be the culprit (more importantly the ACL looks like it is just preventing users from deleting anything).
One thing that has always bugged me about Mac OS is that when a network share becomes unresponsive or unavailable the shortcut on the desktop disappears and you get a glaring messaging that the share has been disconnected.Is there any way to prevent a network share from being removed just because it becomes momentarily unavailable?As an example, on a Windows machine the network share shortcut remains, you simply cannot use it but it is there and ready to go the moment the share comes back online. Is there some way to make OS X behave in this manner? Or is there a way to extend the time out interval for a network share?
My neighbor has an IMac with OS 10.4.11 installed. When I open System Preferences and select the Network icon, the Network window comes up but it is overlayed with a message that states: "Your network settings have been changed by another application." When I click OK, this same overlaid window comes back.
The only way I can get out of System Preferences at this point is to do a Force Quit. In other words, because this overlaid window appears, I am unable to access the Network window to look at TCP/IP settings, make changes, etc.
Next I went into System/Library/Preference Panes/Network.prefPane(more info) to look at the application that appeared in the "Open with" field. It stated "System Preference." I replaced this with a new "System Preferences from the Applications Folder, but the same thing happened - even after I rebooted the computer.
Please let me know how to solve this problem so I can access the Network System Preferences properly.
I just recently installed Windows 7 on my macbook pro. Everything seemed to work well, especially after I installed boot camp for windows and its drivers.
However I can't seem to connect to the internet. My router is detected but when I select to connect to it I get no internet access.
currently I connect to the internet by doing this: Go to System Preferences / Network. Then I select my internet provider name on the left pane and finally click on the Connect button. That's all. This internet profile has a PPoE service name, an account name and a password. My internet connection uses a cable DLink router (it's not wireless).Â
Question:Â
1) Does the password I mentioned above mean that my neighbors can't access my internet, or are they able to do that and, in this case, I need to set another password somewhere else?Â
2) If I need another password, how and where do I set it,
I have my desktop mac connected to my macbook pro via ethernet and am sharing the laptop's wi-fi internet successfully with "Internet Sharing", but is there a way for that tethered desktop to access other Bonjour listings (file server) on the main network through the laptop's wi-fi? (Setup: I am temporarily working on the desktop in a room that doesn't have ethernet access and my LAN from airport extreme are in another part of the house)
Is there a way to take my iTunes account off a computer, that I dont have access to, so that I can put it on my new macbook pro? I have already had my iTUnes on 5 different computers.
My computer name always keep changing with a message like "computer name X already exist in your network and your computer name is now X(2)". I have to change the computer name back to X, or the computer will be rename to X(3), X(4) .... etc. I did not change anything in my network.Is there any way to stop this?
I accidentally set up a computer to computer network and I cannot figure out how to make it go away. I also tried to password protect it, to at least lock it down, but the password is removed from the network as soon as someone logs on (and doesn't require a password to do so). Something is fishy, to say to least. I was told to go into my preferences (through Library) but I don't know what to make of the omnioutliner files. How do I get rid of this network?
I have an iPhone and when I'm in my house I like to use wifi from my Mac. I'm running leopard 10.5 osx. I go to AirPort, create a network and I see it on the mac and iPhone. After I turn the computer off and back on it's gone. Is there a way to create a network that will not disappear?
I have a unibody MacBook late-2009, latest update of SL 10.6.4.
I am attempting to use a computer-to-computer network from my MacBook to my iPod Touch 3G to use an application called TouchOSC which controls Ableton Live on my Mac.
I can Create Network just fine. It sets up the network inbetween my Mac and iPod perfectly. But once I disconnect from the created computer-to-computer network, that network disappears like it was never created. To use computer-to-computer again I have to re-create the network all over.
All of my other networks are stored just fine and I have no other problems with my house Wi-Fi or any others. I have reset my Network Preferences by deleting the SystemConfigurations files and still nothing doing about the computer-to-computer problem.
I am not sure if this is desired behavior, and if it is, is there any way I can save the network I created for later use? Setting it up every time is painful, I want to use it nearly everyday for music.
I have a MacBookPro that I use in my room connected through ethernet. I am at university and they have only allow one machine to connect to their wi-fi that is available across campus, through mac address filtering. I also have an iPhone which I would love to use wi-fi on, at least while I am in my room lounging around and such. Anyway, the point being, can I use my MBP (connected through LAN) to act as a router so that my iPhone can connect to it? Essentially create a wireless network, so iPhone would find it and I could go online on it via wi-fi?
I tried going on Airport and clicking on "Create a network" (w/o a password), but I get an error saying "There was an error creating our Computer-to-Computer network." It doesn't say much else -- is there a better way of doing this?
The title pretty much sums it up, both computers are in the same workgroup (HOME) and I can see both computers in each network overview (when you click network in my computer on both the mac and pc).
