Sharing internet connection over bluetooth

i have 2 computers less than 10 metres apart, one of which is connected to the internet broadband. the solution for sharing the connection wirelessly with this particular setup is rather expensive.
i was wondering if it would be possible to share the internet connection on the computer that has it over bluetooth with the other computer.
i read an archived response suggesting that it was. can someone confirm?
just to be clear:
i hoping to have 2 computers bluetooth connected the second of which will be able to connect to the internet via the 1st computers connection.

While it is not explicitly supported by OS X, both machines can be configured to do this. For lots of reasons, I don't think that this is a good idea. Your Bluetooth link is so slow compared to either a wireless—or even much faster terrestrial—ethernet link, that it's not worth the effort to enable this service.
Save yourself a great deal of grief and disappointment, and get ahold of a relatively inexpensive ethernet gateway [wired or wireless] and set up a small local area network. You will be far more secure, and enjoy a far better level of performance than you would see if you attempted to create a Bluetooth LAN.
That said, here is a set of instructions for enabling internet sharing using Terminal commands. It's paraphrased from…
http://www.macgeekery.com/hacks/pppoverbluetooth
In the Bluetooth preference pane's sharing tab, make a new Serial Port Service and name it bt-ppp and make it an RS-232 device. If it's on, disable internet sharing in the Sharing prefpane. Then create the following script [shown below.]
The script starts pppd on the new Bluetooth serial device you've created, then sets up IP forwarding, NAT, and the like. The en0 can be replaced with en1 if your primary net connection is AirPort. You can change the IP listed to something appropriate for your network, as well. If you put it in the range of IPs you're already using for your home network, natd is smart enough to work as a router instead of a gateway. Run as root, but—for the love of all that is holy and just—use sudo instead of su.
This is the script you must run in terminal:
/usr/sbin/pppd /dev/tty.bt-ppp 115200 noauth local passive proxyarp asyncmap 0 silent persist :10.1.1.25 &
/usr/sbin/sysctl -w net.inet.ip.forwarding=1
/usr/sbin/natd -same_ports -use_sockets -log -deny_incoming -interface en0
/sbin/ipfw add divert natd ip from any to any via en0
If you are unfamiliar with issuing commands from the Terminal or are not familiar with what these unix commands mean, I would suggest that you proceed very cautiously, and do more research before attempting this.

  • Problems sharing internet connection over airport

    Hi everyone-
    I've researched the heck out of the forums and still cant figure out what's happening with my system. I've got a MacBook Pro with OS 10.5.2. In previous OS versions (10.4) when I was successfully sharing my ethernet internet connection, the airport icon in the status bar showed a vertical "up" arrow, indicating that my connection was being shared.
    I'm trying to do the same thing in OS 10.5.2 but not succeeding in getting the same notification. I'm finding that when I access the "Sharing" folder under "System Preferences" and select "Share your internet connection from: ethernet" and "To computers using: Airport" that both settings grey out, the "Internet Sharing" button turns green and the status says "On", but no sharing occurs. I've checked using other wireless laptops and a wifi finder, but no signal from my MacBook is ever found.
    I've deleted my preferences folder to start fresh, no help. I've tried sharing from different ethernet sources, no help. It just feels like the problem is in the OS somewhere, not with the internet connection.
    Any insight or help would be greatly appreciated! Thanks!

  • Sharing internet connection over wifi - 2 questions

    I have a Mac mini that is connected to a cable modem by ethernet, and then broadcasts a wireless network to share that connection. It seems silly to buy a wireless router when one of my computers can be the router.
    The mini's firewall is enabled, and has a few ports open to allow computers on the network to use email, web, ssh and other services. I have two questoins that have been nagging me about this setup:
    1) I can log into the mini from outside via ssh with its IP address. But what if I want to log into another computer on the network? My iMac has an internal IP address of 10.0.x.x... how do I ssh to that address from outside the firewall? Would it look like "ssh y.y.y.y:z.z.z.z"?
    2) When I tell my firewall to block all UDP traffic (seems like a sensible option to make the setup more secure) email and other services no longer work on computers on the LAN. Must UDP traffic be open for the internet connection to be shared?

    >1) I can log into the mini from outside via ssh with its IP address. But what if I want to log into another computer on the network? My iMac has an internal IP address of 10.0.x.x... how do I ssh to that address from outside the firewall? Would it look like "ssh y.y.y.y:z.z.z.z"?
    You can't log into a system 'behind' the Mini without playing lots of games regarding port forwarding (for which there is no built-in GUI). In addition to that you can't use port 22 since that will always point to the Mini itself. What you'll have to do is use some other port (e.g. port 2222) and have the mini forward that to port 22 on the internal machine. Then you can connect to port 2222 on your public IP address and get forwarded to the internal machine. PITA to manage, though.
    >2) When I tell my firewall to block all UDP traffic (seems like a sensible option to make the setup more secure) email and other services no longer work on computers on the LAN. Must UDP traffic be open for the internet connection to be shared?
    Blocking UDP is no security feature at all - either your machine is listening to the UDP socket or it isn't.
    In any case, DNS typically uses UDP, so you're blocking your DNS queries and that's most likely to be what's hindering your network.

    You might want to try resetting your router and your modem - just unplug the cords, leave them unplugged for about 3-5 minutes and then replug the modem and then the router in that order.
    This may or may not correct your problem - call back if it doesn't.

  • Connecting to shared internet connection through Mac osx 10.7 wifi

    I can't get my new HP touch pad to connect to my wireless network. I connect my iMac through ethernet but have a wifi network setup from my iMac so my other devices can use my iMacs shared internet connection. The touchpad will not connect, it finds the network, I put in the WEP key and it states "unable to connect, try again". I am at the setup stage on the touch pad and can't get any further!!. I have tried everything I can think of including creating a new wireless network, disabling and changing the sharing password and re-enabling. all my other devices still log on fine and can connect to the internet through the iMacs connection. anyone got any ideas?

    I just remembered why I ignored your first post when reading this topic:
    Ad-hoc-sharing can't be the problem, because when I use the exact same method without any WEP encryption, so create an open network, it works perfectly - so it has to be an error in the webOS' handling of WEP or similar...
     I'm curious that the Mac offers only ASCII (key length of 5 characters) or 128 bit encryption, but not 64bit (which has a key length of 10 hexadecimal characters and works perfectly with my touchpad).  <Wiki definition of WEP.>
    This sounds like an old problem we used to have when Palm came out with WiFi-enabled devices. Users would create an ASCII text password in their router, and it would generate a 10 character hexadecimal string that was the true password.  Entering the 5-digit ASCII code would fail since it was a seed, and not the "real" code.. Entering the 10-digit key worked every time.
    By any chance is this what is occurring on the Mac? Do you see a 10 digit code generated anywhere in the setup routine?

  • Sharing internet connection - HOW?

    I'm sharing internet connection with a PC via netgear. Now we want to add another ibook to the connection. How do I open the network so that it can share the connection? It keeps saying that the network password is incorrect, when it's not... Any ideas?
    Thanks!

    Are you using WEP?
    One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
    In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
    The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
    One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
    Though sometimes not even that works and the HEX key must be used regardless.
    I have found this to be the case with all the Netgear routers I have used.

  • Sharing Airport Internet connection Over Ethernet

    Hi
    I've read various things about this on the forums here, but none of them seem to make a considerable amount of sense seeing as the person just magically works out the problem. So I'll attempt to describe my problem.
    I'm trying to share my Intel iMac's Airport connection to another mac running 10.4.6 over ethernet. I'm using crossover cable, and so far I've got the two computers to recognise each other in Network tab of the Finder, so I can mount the other's HD on my desktop if i wanted. BUT, I am having no luck with sharing my internet connection, I have the 'Share my Airport connection over Ethernet' settings ticked in System Preferences on the iMac with airport, but the "light" on the network overview page is orange on both computers, and the one connected with ethernet does not connect to the internet.
    Any idea what I may be doing wrong?
    Thanks a lot
    Mo

    You are sharing one connection from the main unit to a secondary unit. The secondary unit only has access through the main unit, so the system doesn't see a personal web connection, just a web connection. In order to share that connection, it must be seen as a "personal" or directly connected form of network. This is so that somebody can't just steal your connection and then filter it to a billion computers and hack you and really mess up your system. If you want to share that connection, I suggest you invest in a wireless router. Then you can share all peripherals from the main unit and other units in any configuration you wish, and then use your secondary(wireless) unit to share directly to the third unit(crossover cable) without having to set a bunch of manual controls and troubleshoot. Printers, some scanners, and sometimes even dvd burners can be shared across a router. And because the system reads two connections(comp-to-comp and comp-to-web) through the router, you can actually fully network all peripherals to work across each unit, so long as they all run the same versions of OS and software. Just remember, you get what you pay for with routers. $100-$200 should get you something decent and a USB speed-booster card wouldn't hurt if you can get it as part of the whole router package. I've used the same type of configuration and it has saved me days, even weeks of trying to move data onto cds and dvds to move between computers for using with different programs and tasks.
    good luck

  • Why does my iPhone not show up in iTunes on a mac that has a shared internet connection from another mac?

    I have what I would consider a difficult question. I called Apple Care and after she spoke to a senior advisor,the representative ended up saying it wasn't possible.
    Having said that, I'm sure this is not a difficult question for people with networking expertise.
    Setup
    So...I have a MacBook receiving a WiFi signal via AirPort.
    In System Preferences, I have turned on Internet sharing (share airport over Ethernet).
    I connected the Ethernet port on my MacBook to the Ethernet port on my MDD PowerMac G4.
    At this point, I can successfully browse the web, perform software updates, and view other computers and iTunes libraries on my network from my G4.
    Goal
    However, in iTunes on my G4 I would like to use iTunes DJ.
    Tried
    So...I click on iTunes DJ.
    I set the settings (button in bottom right) to allow guest remotes, etc.
    I turned on iTunes Home Sharing (logged into the same account as by iPhone).
    Problem
    However, from the Remote app on my iPhone, I am unable to see the library on my G4.
    Also, if I want to pair my iPhone Remote app with iTunes on my G4, I click add Library in the Remote app, but iTunes on the G4 never displays my iPhone in the left column (although I am able to see all other iTunes libraries being shared on the network).
    Thus, I cannot connect to iTunes as a guest Remote, nor can I connect as paired remote.
    I have successfully done both of these things with computers connected directly to my modem, as well as with computers connected via WiFi.
    The problem is connecting devices to computers that get their internet connection though another computer via internet sharing.
    Question
    So my question is about Internet sharing itself. Is it not a fully featured ad-hoc network? Does it only provide browsing capabilities and the ability to browse networked computers, but NOT devices such as an iPhone? I don't see the difference; my iPhone is on the same network as the computers, so why is there no communication between it and computers that gain their Internet connection through another computer?
    I really hope someone out there who is an expert in networking can help me out with this. Or if it truly is impossible, if someone could explain to me why that is the case, I would also appreciate it.
    ps. I usually have my MacBook sharing its Internet connection through an old router that I am using as a switch because I share the connection with three other computers. And if it isn't obvious, the modem is downstairs, and the MacBook, old router being used as a switch, and other computers are upstairs where there is no Ethernet wired.
    Thank you in advance for any help.

  • Airport network and sharing Internet connection

    Hello all,
    I have hit this problem with sharing an internet connection on an airport network. Maybe its a simple fix, maybe it a "can not be done", answer.
    My set up may be a little hard to describe. To explain, completely wireless set up in my network, 1 x imac and 1 x powerbook, all on airport and using an airport express. This includes my new printer. All connected through airport express network, call it network A.
    Up till now i had a modem with an ether net cable plugged into the airport express. All was fine.
    I am in jakarta, the cable internet providers here are hopeless, slow connection speed.
    Last month a new wireless internet service was released. Called 3.5 G. Its lightning fast and reliable. Basically you get a wireless USB modem attach it to your computer and you are always connected to the internet wirelessly. You can travel anywhere with it. The 3.5G is primarily for mobile phones but i use it just for internet. This modem is connected to my powerbook and works great.
    Now, the useless cable internet connected to my airport express is still connected for my Imac to use.
    My problem is that i would like to share my high speed internet connection from my laptop to my imac. Problem is that when i allow sharing from my laptop, the intenet works fine on both machines but on the powerbook, which is doing the sharing you get an arrow symbol through the airport icon at the top.
    The laptop can NOT access the local airport express network A. Hence i cannot use the printer or see the imac. That is my problem, i cannot print from the powerbook unless i stop sharing. When you share an internet connection the sharing computer seems to create another computer to computer network and does not join the existing arirport network.
    This is probably a little confusing. Hopefully, someone may have some ideas. My alternative is to buy a new fixed position modem/router for the 3.5G system. Its about $600. Ouch.
    Any ideas
    thanks for the interest.
    joe

    Selamat Phil Smith,
    Actually do we know each other, cause i know a phil smith.
    Actually an ether net cable is OK for the short term. But if i get another computer it may get complex. Spent a lot removing cables too.... Looks like i will have to buy the special modem router... Painful $600.
    This share internet thing over airport looks like a great idea till you realise it disables access to the ariport network for the computer doing the sharing.
    Cheers and thanks for the idea
    joe

  • Problems sharing internet connection - works only one way...

    hey all,
    i'm having a problem sharing my internet connection between our "new" iBook G4 and "old" iMac G5. (both machines are running 10.4.10.) i've seen several posts here that seem related, but no answers that have worked in my case.
    here's the gist:
    ideally, i'd like share the internet connection from the iMac (from our cable modem) to the iBook over the airport. so, i've set up the iMac to do this under "sharing" in system preferences. i then set up the iBook to connect to this new wireless network. under "network status", it says the iBook is connected to the iMac's network, but that the iBook doesn't have its own IP address, so it can't connect to the internet.
    oddly, when i reverse the process - i.e. plug the modem into the iBook and share the connection over the airport to the iMac - it works fine. the iMac gets its own IP address and can see the internet.
    a friend suggests that somehow the iBook is set up to distribute IP addresses as a router, but the iMac isn't. fine. but, i don't know how to make changes to that function.
    any thoughts?

    well, it's taken all day - many, many attempts. but i've finally found something that worked. the answer was burried in the middle of this guy's blog page:
    http://www.tuaw.com/2007/03/26/how-to-using-your-mac-as-a-nat-router/
    he says:
    "I've turned off DHCP and set the address to: 192.168.0.1 and the subnet to 255.255.255.192 In making these choices I was following a hint that appeared at macOSXhints back in 2002. Once this is done I went back to the Internet tab of Sharing Preference Pane, select en4 and start it.
    "Now on my other device (in this case a Xbox 360) I set it up as follows:
    "IP address: 192.168.0.2 subnet: 255.255.255.192 (this is the same subnet of the en4 USB interface, above) gateway/router: 192.168.0.1 (this is the address of the en4 interface) DNS: 192.168.2.1
    "(here's where the voodoo comes in, I have no idea why this DNS setting works. You would think it should be 192.168.0.1, or even the DNS server of my ISP, but those simply do not work. I suspect that it has something to do with sharing over Airport as well).
    "I've also found that this will only work properly if Internet Sharing is active for my Airport interface. If I turn off the Airport interface (en1), the wired interface (en4) also dies. With these settings in place, everything seems to work properly. Keep in mind you may also need to enable certain services (which will vary with your application) in the Services tab of the Sharing Pane:"
    i wasn't trying to solve quite the same problem he was, but by manually inputting the IP addresses, etc, that he did, as well as randomly enabling other "sharing" options (FTP access, etc) which seemed unrelated to internet sharing, it finally worked.
    can anyone explain what this is about? it all seems pretty cryptic to me. i'm not sure what i even did...
    no complaints, but it would be interesting to know.
    thanks!

  • Sharing internet connection using 4200 speedstream with airport express

    I have xp windows sp2 loaded on a desktop with ethernet connection to a modem and have a macbook pro laptop using airport express. I have to reset the modem to full bridge mode to access the internet when using airport express wireless connection,this disables the connection to the internet on my desktop ( the error displayed is low conductivity through the modem). To get my desk top to work on the internet I have to reset the modem and set it to optus bridge. This allows access to the internet but disables my airport express connecton.
    Is there a way to allow sharing my connection to the internet without reseting the modem.

    G'day mate,
    The SpeedStream 4200 supplied to Telstra BigPond customers is a single user device, connect it to a 'Switch' or 'Router' to share the Internet Service or, replace the whole thing with an ADSL2+ Wireless Modem Router and get coverage all over your house.

  • Sharing internet connection with a PC

    Hi, I have a macbook with the latest OS X. I want to know if it is possible to share my PC's internet connection with my laptop, either through wifi, bluetooth, or firewire. I am running XP on the PC. I will not have a wireless network up, and I would like to have internet on both my mac and my pc. Is there a device that i can hook into my PC to broadcast a wifi network. It doesnt have to have a large range, I'll be using my laptop close to my desktop.
    Macbook   Mac OS X (10.4.7)  

    Really cool feature alert. Under System Preferences-->Sharing you can have your Mac share to any computer connected via Wi-fi, Firewire, or Ethernet. Whichever adapters are not used for the Internet connection are available.
    It saved me lots of grief setting up some stubborn Windows boxen that only loaded the firewire driver as the OS was setup.
