[SOLVED] OS X Internet Sharing to arch over ethernet

I previously had this working with arch's gateway set to the mac's ip and both subnet mask the same, but now OS X just shows the cable as unplugged.
Any recommendations on how to set my rc.conf?

I do not have the newest rc.conf. I haven't run pacman in quite some time.
This is my setup:
Internet <--wifi--> OS X <--ethernet--> Arch
and Internet sharing to Ethernet from Wi-Fi is enabled in the sharing pane on OS X.
Mac's network configuration
Arch's configuration:
eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
INTERFACES=(lo eth0)
gateway="default gw 192.168.0.1"
I've obviously set the linux box's gateway to the mac's IP and both have the same subnet mask.
And, the stupid cable is clearly plugged in!

How to Internet sharing from AirPort throuhg Ethernet

Hi! How to Internet sharing from AirPort throuhg Ethernet?
In System Preferences -> Sharing -> Services not found checkbox for Bluetooth Share Internet
Internet is connected via airport
Mac os x 10.4.11 Server
Thanks!

I've not set up a Bluetooth PAN; a Personal Area Network. Modems and keyboards and such, yes.
My usual approach here would be a WiFi USB widget, or an embedded WiFi card or a PCMCIA / PC Card or a CardBus WiFi or wired network adapter, or a wired Ethernet connection for the Windows Vista laptop.
This to connect from the Windows Vista laptop to the AirPort, or into a wireline Ethernet (if there is one). And from there to the Mac Mini server running Mac OS X or Mac OS X Server software.
As for the PAN, I don't know. I don't have Mac OS X Server running on a box with Bluetooth hardware, either.

Trouble sharing mac internet to linux server over ethernet

Hi. I turned on internet sharing over ethernet to my linux server which is a dell poweredge. I went into network and at first it had a self assigned IP. Then I manually changed it to the correct subnet and the same IP address as my mac. Since I know the gateway is 192.168.1.1 and my mac is 192.168.1.5 ! I realize that the IP address is taken but I didnt know since they share the internet connection and I didnt know wether to assign a completely new IP address or keep the same one as the mac. Thanks

IP address of my mac connection to the base station is 10.0.1.5, 255.255.255.0 subnet, router (Default gateway) address is 10.0.1.1
IP address of my iMac's ethernet going to the switch is 10.0.1.10, 255.255.255.0 Subnet. "Router: 10.0.1.1"
There's your problem.
You have the SAME subnet for both interfaces on the iMac. This is not valid, and will prevent internet sharing from working
Each interface has to be in a different subnet. If your wireless link is using 10.0.1.x/255.255.255.0 then your wired interface has to use something different. Choose either something else in the 10.x.x.x range (e.g. 10.1.1.x/255.255.255.0), or something completely different (e.g. 192.168.1.x/255.255.255.0).
Your PC will need to have an IP address in the same subnet as the iMac's wired interface and its gateway address should be the address set for the iMac's wired interface.

Internet sharing from Wifi to Ethernet is not working after Mountain Lion upgrade

First I was having trouble just connecting these two, now I can't get the Internet sharing to work. Here's what I am trying to do: I want to share my Macbook Pro's internet connection from it's Wifi to another laptop I have connected via ethernet cable. They will ping each other now. The problem now is that the laptop won't pick up the Internet connection from the Macbook Pro, even though I have it configured exactly as I had in Snow Leopard. Nothing has changed on the laptop from before when it worked fine with Snow Leopard. But now that I updated to Mountain Lion, Internet sharing no longer works no matter what I try. I've been trying to find a solution by to no avail. Could anyone here offering some advice or a solution that will fix my problem? I've been over the basic steps over and over again, so please don't ask me to do something stupid like reboot or check the Sharing settings. They're exactly how they are meant to be, but the thing just won't work.

Ran a TCPdump on my Macbook Pro. It is recieving the ping requests, but the laptop still isn't getting replies to its pings. So something is wrong in the Macbook's configuration somewhere. I don't know where, though.

Internet Sharing WiFi **TO** Wired Ethernet

Back Ground:
I have a Late 2013 MBP Retnia.
I have WiFi access via a captured portal.
I have other WiFi and Wired (Ethernet) devices that can not authenticate to a captured portal.
Question:
1) On the single MBP mentioned can I connect to the captured portal WiFi via one band (say 2.4) and then become a WiFI hotspot with the other band (say 5)?
2) On the single MBP mentioned can I connect to the captured portal WiFi via one band (say 2.4) and then share the Internet connection to the Thunderbolt Ethernet connector?

Hi gregbogus,
Checking the Internet Sharing options in the Sharing System Preference, there's not an option to specify which wireless band is used for what, but you can share from Wi-Fi to Ethernet (or vice versa).

Streaming iTunes (shared library) video over ethernet...

I'm hoping someone with combined iTunes and networking savvy might be willing to help me out here. Here's the setup,
I have an Intel iMac hooked up to Fantom 1TB drive via USB 2.0 (iTunes library on external). The iTunes library is shared to an iBook G4 over ethernet via a Linksys Wireless B router (but both comps are wired in for max speed). (To be clear, when I say 'shared' I mean that I open iTunes on the iBook with it's own library and select the shared iMac library from within the iTunes GUI). When I go to play videos over the shared library on the iBook they are quite choppy and slow and I'm wondering where the bottleneck is.
I'm using Cat5e cable (1000Mbs+ so far as I can gather), but the router ports are 10/100 as is the ethernet port on the iBook (max 100Mbs). Further, the iBook has only 32MB of VRAM (although I've upgraded the RAM to 1.12GB). The iMac is running Leopard 10.5.5, iBook running Tiger 10.4.11, both machines running iTunes 8.0.1. I'm presuming that the read and transfer rates of the external are not the issue here because there are no problems viewing on the iMac, but I could be wrong.
So is the bottleneck the 10/100 ethernet ports on the router/iBook, the iBook VRAM, or is there something inherent in iTunes library sharing itself that is causing the delays? I also have an Xbox 360 which reads the same shared library via Rivet/Connect360 over the same network and router and videos are fine on the Xbox which makes me think the problem is with the iBook or iTunes.
I ask because I'm considering upgrading the router, and even replacing the iBook, but if it's something to do with iTunes itself, then there's not much point.
Thanks to any and all who can offer advice.

This evening I tried to narrow down the problem further and I think it boils down to the iBook not being able to process the video data fast enough rather than the transfer rate over the network or something inherent in iTunes.
To do this I shared my library folder on the network and copied a file from it to the iBook's HDD, adding it also to iTunes locally on the iBook. The quality is the same whether I view it:
1) Through the iTunes GUI 'SHARED' library over the network
2) By opening it directly (using Quicktime) over the network through the mounted shared folder in finder
3) Viewing it in Quicktime directly from the iBook's internal HDD
4) Viewing it locally in iTunes from the iBook's HDD
Now the question is whether the iBook should be able to view this video smoothly given its hardware, or do I have the logic board VRAM problem that I've been reading about...I guess an issue for another post/topic.
Thanks for trying to help Tom.

Internet Sharing - MPB with Wirless Ethernet out to iBook G3

Okay i've got an MPB getting wireless, and i am connected to a iBook G3 via Ethernet. Trying to share the wireless connection to the iBook via Ethernet cable. I need a step by step help here because i have no clue where i am going or how to make this work. Apple help files have not really been successful at all. Any help is appreciated.

It's pretty simple. What you do is…
1) On your MBP go to the Sharing System Preference > Internet and select Airport in the "Share yur connectin from" setting. Enable the Ethernet port in the "To computers using" list.
2) Click on thr Start button.
3) On your iBook go to the Network System Preference > Built-in Ethernet go to the TCP/IP tab and ensure that "Using DHCP" is used to "Configure IPv4". Apply the change in need be.
You should now have the connection working. However, one thing you need to be careful with is the Firewall on your MBP. If any port is not allowed to pass through your firewall it won't pass through your connection sharing either. So firstly turn off your firewall and check to see if it's working. If it is turn it back on and start opening ports that are required by the iBook.

Internet Sharing Ethernet to WiFi disables WEP password on Mac Network?

Hi all,
I have a curious problem, I'm trying to use internet sharing to share the ethernet connection to my iMac with my iPhone and iPad over wireless (no wifi where I live).
I can create a network with WEP fine, name it whatever, encrypt it with whatever, my iPhone can connect to it etc. but as soon as I turn the tick box for Internet Sharing on, the network loses its WEP encryption (so it's unprotected) and its name reverts back to "My Name's iMac", even if I set it up as "3423rfgdfgfdg" with WEP.
Basically turning on Internet Sharing overrides all the options I set up on the network, name, security etc and my WiFi turns into an unprotected internet source and a broadcast of my name, something I don't want where I live.
Am I crazy in thinking this is a bug not a feature and there must be some solution?
I honestly look forward to seeing what you guys think, I'm stumped.
This all used to work perfectly on Snow Leopard, I remember quirks during Lion but I got it to work in the end but I'm on ML now and it just doesn't want to work.

Hey, thanks for the suggestion but that's exactly what I'm doing.
See how after you've selected Ethernet in 'Share your connection from' and WiFi in 'To computers using' you then have to click the tick box ( http://cl.ly/image/1v191f2R1F1i ) on the left hand side to actually start the whole process?
Well regardless of whether I start it up in the 'Sharing' pref first, then set up Wireless options, or set up wireless options, then start it up in the 'Sharing' pref, whatever settings I choose get overriden as soon as I start the sharing.
The network just defaults to 'Asad's iMac', without protection. I don't understand why.
P.S. on a side note when creating networksI'm not offered a WPA2 option. Only WEP 40-bit or 128-bit. Dunno if that's connected: http://cl.ly/image/2X2g3w3y0B34

Internet Sharing between Mac Mini and Windows 7

Hi all,
I installed Lion yesterday on my parent's Mac Mini. We use the Mini's Internet Sharing to connect the other computers in our house to the internet since we're only home a few months of the year.
After setting up Internet Sharing I jumped over to my HP G62 and connected to the new network. It found it but I can only load a few websites off of the connection: Google, Youtube, Netflix(sometimes) and my school's email. Everything else just endlessly loads - I can't follow links through Google searches, can't input the URLs directly, nothing seems to work except those few sites.
The websites work fine while I'm on Mini, and all of the settings appear to be the same as when we were running Snow Leopard - minus the change to WiFi instead of Airport. I also seem to be getting a slower connection on my HP, it's registering between 52Mbps and 65Mbps - it used to register at 100Mbps.
Any ideas?

Same here, but I am sharing from a WIFI connection to an Ethernet device.

Can't create airport/wifi internet-sharing network with other laptop

I have an iBook running Tiger 10.4.11 connected to the net with ethernet. The internet connection comes through a radio antenna which acts like a router to which I don't have access.
I want to share my internet connection, and to be able to transfer files, between the iBook and another laptop. I've tried it with two - one running Fedora 11 (mine) and one running Windows XP, and have the same problems with both.
I turn wifi on on the ibook and linux laptop. I turn on internet sharing from built-in ethernet to airport in System Preferences. First I try it with no encryption. 'Other settings may interfere with internet sharing' shows up; it tells me to enable Personal Web Sharing, which I do. When I click start Little Snitch tells me natd wants to connect to 10.0.2.1 (presumably the router in the antenna), which I allow. I try to connect with the linux laptop and it tries then disconnects.
1) isn't personal web sharing for serving web pages? — why is it necessary here at all?
2) what am I doing wrong in making my network work?
If I enable encryption using WEP, the other password asks me for authenticication, I put in the password, and it then tells me the network has been disconnected.
3) is WEP the best encryption I can use from Tiger?
4) I think the problem's with Tiger (both laptops can connect to other wifi networks not set up by me). Is there a piece of free software I can use to share the connection instead of the built-in one?
I can't make a functional network in reverse either (i.e. setting it up on the other laptop and trying to connect wirelessly with the ibook).
What I am trying to do is precisely this (http://my.safaribooksonline.com/0596009135/runmacx2-CHP-11-SECT-13) — it just doesn't work.

When I click start Little Snitch tells me natd wants to connect to 10.0.2.1 (presumably the router in the antenna), which I allow. I try to connect with the linux laptop and it tries then disconnects.
Back on that part, at that Point the Mac is a NATD Router, don't try to connect to the other computers.
On the Mac, with Internet Sharing enabled, open NetInfo Manager in Applications>Utilities.
From there on out, it's a bit foggy, but iirc Config>DHCP>Subnets><the subnet>, then down where it says com.apple.nat... what does it report for IPs?
If it were say 10.43.29.1 then the others trying to join should have that as a Router/Gateway, and then 10.43.29.2, 10.43.29.3, etc. as IPs.
Apple says you can't set it Manually, but I've had it work a couple of times.

Touble with Internet Sharing since latest Aiport Update

Up to yesterday I was able to share seamlessly my internet connection on my iMac using built in airport as a router. Since the last update, every time I open internet sharing is running on my iMac while connected to the internet, sharing my connection from ethernet using Airport within 30 second of my iPod been connected to my Wireless signal my internet connection die, and can no longer access the internet with my iMac or iPod. The only way to get back my internet connection is to disable internet sharing in system preference.

Just to be clear,
1. You are connecting fine on your iPhone (meaning that you have the 3 bars next to your Carrier in the top left of the screen)
2. you can't access the internet on you iPhone
Correct?

AT&T microcell and internet sharing

I have an Airport Extreme connected to my cable modem, with an iMac 10.6 connected though the Airport. I just got an AT&T microcell which normally connects to the Airport ethernet port giving me better iPhone calling. I want to instead connect the microcell to the iMac ethernet with internet sharing enabled, through this ethernet port. The microcell doesn't like this, ethernet connection light just blinks and the network cp ethernet port says Self-Assigned IP. Can I make this configuration work somehow?

It won't work that way. The Microcell needs a wired connection all the way back to the router.

Internet sharing not working in lion. Bug?

Hi guys - Internet sharing of my office ethernet connection is gone. It just doesn't work anymore. I hope that if we insist flagging this, they will fix it. It was really useful at work to share my connection with mobile devices.

Seems like there is no fix yet. Whenever I turn on internet sharing, the wifi will get a self assigned ip of 169.X.X.X and no wifi devices like iphone can get an ip by connecting to this network. It was working fine prior to Lion.

Internet sharing ***** on OS X Lion 10.7.1

Internet sharing doesn't work on OS X Lion 10.7.1 (niether in 10.7.0)
If I create a network with my MBP, and turn on Internet sharing (I have an ethernet cable plugged in, and share the internet via Wi-Fi), the device can connect to the network, but theres no way to have any bits of internet. What can I do in this situation???
Please help, and fix this bug in any update.

Same problem here. Sharing via Wi-Fi works though.

Firewire Internet Sharing Probs

Hi, looking for help to resolve the following issue: On my Firewire connected cpu, I can't get past the "You are not connected to the internet." dialog in Safari. Reaching the conclusion that one or more of my settings are incorrect.
1st). 24" iMac w/ 10.5.1; connected to Cable modem via Ethernet
(there is a 5-port switch prior to this cpu)
Sharing > Internet Sharing (Firewire) - ON
Network > Ethernet > Manually; IP Address: 69.92.45.xxx - Subnet: 255.255.252.0
Router: 69.92.xx.x
2nd). Dual 1 GHz Quicksilver w/ 10.4.11; connected to 1st cpu via Firewire
Sharing > Internet Sharing (Firewire) - OFF
Network > Ethernet > Manually; IP Address: 69.92.45.(same as above *plus 1*)
Subnet: 255.255.252.0 - Router: 69.92.(same as above)
I can see & browse files within Network > Servers yet, I'm not able to access the internet.
Might anyone have a suggestion for this prob? I have searched for the answers w/ no concise results.
Thank you for any help,
Sim

simoom,
I'm surprised you're getting anything, on either computer. Let's see if we can't get you straightened out.
First, computer #1 needs to get its IP address via DHCP, not manually (unless your ISP has told you otherwise; not very common). Plus, it would be a good idea to get rid of the switch. A switch is OK if it is downstream of a router, which itself acts as an internal DHCP server, but not when connected directly to a modem.
So, computer #1 should be connected directly to the modem. It will talk directly to your ISP's DHCP server and acquire an IP address. It would appear that the Firewire Sharing is set up properly, so this should be fine once an IP address is nailed down.
Second, computer #2 needs to gain an IP address the same way: via DHCP. When computer #1 has Internet Sharing turned on, it acts just a router would, issuing "private" IP addresses to the connected computer(s), then acting as a NAT router. On computer #2, configure a Firewire network port, and set it to look for an IP address via DHCP.
