Link-local only: Only create a link-local fe80::/64 address via StateLess Address AutoConfiguration (SLAAC). Link-local addresses are not publicly routable. This is the IPv6 equivalent of IPv4's 169.254/16 link-local addresses. The base station will be reachable via IPv6 only from other devices on the data-link networks (wired and wireless Ethernet) directly ...

Depending on your reason for turning off the Airport card (as in use the wired connection instead of the wireless when it's plugged in) you may not even need to turn off the Airport card. If you go to the Network Preference Pane in System Preferences it's possible to set a Service Order so that when one is active it takes precedence over others. For example ...

The definitive reference for questions such as 'Which interface will be used to reach host w.x.y.z?' for any given time or situation is to refer to the routing table. [mini-nevie:~] nevinwilliams% route get 10.10.10.10 route to: 10.10.10.10 destination: default mask: default gateway: 192.168.2.1 interface: en0 flags: <UP,GATEWAY,...

If he's already broken your encryption, MAC address filtering won't get you anywhere. The easiest and safest way to harden your network is to change the password to your network and enable WPA2 encryption.

See docs for the --address option here: http://code.google.com/appengine/docs/python/tools/devserver.html Basically: On the machine running appengine: Open System Preferences > Network and write down the IP (eg. 1.2.3.4) Use this IP with the address option, ie. "--address 1.2.3.4", when you launch the dev appserver. Visit http://1.2.3.4:8080/ from any ...

Maybe too much overhead, but Marco Polo is a nice application that lets you turn off/on various settings/devices depending on various factors (context aware). I have not tested it, but maybe you can create a rule that turns off the AirPort when an Ethernet cable is connected. However, it is no longer supported by the author. As of August 2013, the author ...

Here's a dump of ifconfig -a in each situation (I'll highlight the differences afterward): Ethernet cable is plugged in: lo0: flags=8049 mtu 16384 inet6 ::1 prefixlen 128 inet6 xxxx::1%lo0 prefixlen 64 scopeid 0x1 inet 127.0.0.1 netmask 0xff000000 gif0: flags=8010 mtu 1280 stf0: flags=0 mtu 1280 en0: flags=8863 mtu 1500 ...

second edit: Apple released a patch for the slow wireless issue here. I will leave the original answer in place in case the patch doesn't fix people's problems. 10.5.8 introduced some serious wifi problems for me as well. The only solution I've found is on Apple's discussion site where someone realised that replacing some system files from 10.5.8 with ...

A couple of things. Mac will always use the network connections in order that's listed in your "Network Connections" profile. For example, if Ethernet is on top of Wireless, Ethernet will take over. I'm not sure on how SSH works that much, but from my experience. If one connection fails or disconnects, SSH will then use the other connection. If you really ...

For those of you finding this page but are running App Engine 1.7.6 or newer, use --host=0.0.0.0 instead of --address 0.0.0.0 A big update in the Development Server resulted in a large number of options being changed or removed (all shortened flags were removed), as well as python 2.5 support being killed. On the upside, the admin host/port can also be ...

Anything that automagically open up holes in your firewall (for instance, as BitTorrent client might use uPNP to get a port opened for itself without direct user intervention) is going to fail, because it can't access the 'outer' NAT. Otherwise, it's a bit of added latency (not likely to be significant) and you're paying to power two devices instead of one....

I use this: if=$(route -n get 0.0.0.0 2>/dev/null | awk '/interface: / {print $2}') if [ -n "$if" ]; then echo "Default route is through interface $if" else echo "No default route found" fi

Frankly, I'm pretty sure Snow Leopard has no (general) problems with any of the major brands of routers out there. Rather than look for a new router, I suggest you first spend a little more time figuring out what your problem is with the one you are currently using. Some questions: The latest update for Snow Leopard is OS X 10.6.4. While I realize it ...

Do you have a static IP address assigned to your Airport interface for some reason? How about statically assigned DNS numbers? If that is the case, it might be a coincidence that the assigned address information is compatible with the neighbors's and mom's networks. Try making a new network location. Go to System Preferences >> Network pane. At the top ...

The IP address 169.254.59.233 is not being provided by your router but is being created by your computer in an attempt to communicate with your router's DHCP server - and failing. You should check the wireless connection to make sure it's actually attaching to the network and the authentication details are correct.

Based on a similar question How can I reset network (Airport) connections from the command line? Create two applescript files: do shell script "/usr/sbin/networksetup -setairportpower en1 on" do shell script "/usr/sbin/networksetup -setairportpower en1 off" Then use fastscripts to assign keyboard shortcuts to them.

There is absolutely no way to change the layout of that dialog. As it doesn't support custom sorting and resizing, you can't change that. But the source for this list is accessible from the following file: /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist You can open/read the file in any text editor, Property List Editor/...

First of all, this AirPort feature relies on a working "dynamic DNS" setup. If you let someone else host your domain and manage your DNS, get them to set it up and get the TSIG key name and private key for updates. If you manage your own, first follow a tutorial on configuring dynamic updates in your DNS server. Afterwards: In the (dynamic global) ...

You can definitely do this. The Airport Express can act as a wireless router, as a wireless bridge, a wireless access point, or in Wireless Distribution System mode as a repeater, or can join it strictly as a wireless client. For this, you want to set up the Airport in client mode. Apple's site has instructions on this. Here's what it recommends: Using ...

Can't the express just ask the cable modem for a helpful answer? Yes it can and I think it will if you leave the DNS address unspecified. (Though technically the conversation is not between your router (Airport Express) and the cable modem. The modem just is a way to move IP packets across the cable back to the computers at your ISP. The DHCP server at ...

When Internet Sharing is on, your Mac is acting as a NAT gateway, not an Ethernet bridge, so it'll block most service discovery and local name resolution protocols such as Bonjour, which use non-routable multicasts (and some old-school bad ones like NetBIOS that use broadcasts). So if you're trying to browse for services on the far side of your Internet ...

I had the same problem. The key for me was that I had a custom DNS server configured. In my case it was googles (8.8.8.8). I remember doing this some time ago for whatever reason. Anyway, the public hotspots don't seem to like this. After removing the custom DNS server I was able to connect fine on public hotspots.

I pulled a PC move and "forced" shut down (held the power button down until it the machine turned off) and BOOM, Wi-Fi was back in action after the next boot. Not condoning this computer taboo, but it might be worth a try.

I can tell you that it's quite possible on a technical basis. The airport express should be able to be configured as a bridge, or a WDS node, and in either case it should both expand network coverage, and provide the same connection via the Ethernet port. Client mode is not suitable for this, as it's designed to allow the airport express to serve as a print ...

You didn't say if you're running in 2.4GHz or 5GHz, and if 5GHz, whether you've wisely left it set to the default of using wide channels. If you're running your AirPort Express in 2.4GHz, it will only use normal (narrow) 20MHz-wide channels so that it leaves room in the band for Bluetooth and other uses. So your maximum signaling rate is 130 or 144mbps ...

I do not believe you can do this. Here is some further discussion. In a nutshell: No, you can't do it, and even if you could, it's pretty useless. Considering the limitations of Internet Sharing, which is meant for quick-and-dirty ad-hoc networking, it's definitely worth spending a few bucks to pick up a cheap router or signal booster instead.

I think you shouldn't try to do this. I used the migration assistant to copy my files So, you've copied your documents and some more (but not the whole backup), after you installed Mac OS X (or, onto a system that had OS X pre-installed)? If so, then the old backup is simply not a good representation of your current Mac. If you could somehow enforce a ...
