Can someone please explain ifconfig output in Mac OS X?

macos ip-address ifconfig

Solution 1

I wonder what each interface is.

lo0 = loopback
gif0 = Software Network Interface
stf0 = 6to4 tunnel interface
en0 = Ethernet 0
fw0 = Firewire
en1 = Ethernet 1
vmnet8 = Virtual Interface
vmnet1 = Virtual Interface

Something like that.

Also, which of these is the IP interface ?

There hasn't been "the" IP interface since many years ago. All of them can have IPv4 and/or IPv6 configured and running. The default one to use is defined by the routing table (in particular the default or 0.0.0.0, ::/0 entry).

I don't see eth0 anywhere, which I assume is the standard interface name used by linux systems.

Mac OS X is BSD, not Linux.

Solution 2

You can see the names that are used in System Preferences for some of the devices by running networksetup -listallhardwareports:

Hardware Port: HUAWEIMobile-
Device: HUAWEIMobile-Modem
Ethernet Address: N/A

Hardware Port: Bluetooth DUN
Device: Bluetooth-Modem
Ethernet Address: N/A

Hardware Port: Ethernet
Device: en0
Ethernet Address: a8:20:66:31:95:57

Hardware Port: MBBEthernet
Device: en5
Ethernet Address: 00:1e:10:1f:00:01

Hardware Port: Wi-Fi
Device: en1
Ethernet Address: 8c:2d:aa:33:03:e9

Hardware Port: Bluetooth PAN
Device: en4
Ethernet Address: 8c:2d:aa:33:03:ea

Hardware Port: Thunderbolt 1
Device: en2
Ethernet Address: 32:00:1b:25:92:c0

Hardware Port: Thunderbolt 2
Device: en3
Ethernet Address: 32:00:1b:25:92:c1

Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: N/A

VLAN Configurations
===================

networksetup -listnetworkserviceorder produces similar output but it displays "a list of network services in the order they are contacted for a connection" or it shows the services in the same order as System Preferences.

networksetup does not include devices such as the vmnet1 and vmnet8 devices used by VMWare.

You can see further information about the en devices by running defaults read /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist:

}

In addition to what iklier said about the device name for Wi-Fi being en0 in laptops without an ethernet port and en1 in Macs with a single ethernet port, it is also en2 in at least some Mac Pros with two ethernet ports.

Solution 3

On older Apple portables, en0 is Ethernet and en1 is Airport(WiFi).

Older Mac Pro's, with Ethernet jack, will have en3 as well as they have two Ethernet NICs and Airport(WiFi).

In newer MacBooks without an Ethernet jack, en0 is Airport(WiFi).

vmnet# is usually created by VMs(Parallels/VMWare)

I customized a codepen pen, which has prefix-free installed, and installed the prefix-free prefixfree.dynamic-dom.min.js, but the code is still not animating. What would I need to do to make this animate (not in codepen but after putting prefix-free in my code)?

You can see the pindrop animation working like it's supposed to here: http://codepen.io/maudulus/pen/ohFiH

+1 Nice answer. Also, sometimes you'll see ppp0, which is also used for some VPN tunnels.
maudulus over 9 years

prefix-free is in my pen now...the problem is that the animation doesn't work outside of the pen.
maudulus over 9 years

The normalize was a typo. Changing the css from @keyframes "bounce" to @keyframes bounce doesn't make the animation work, however. Prefix-free is now added in code-pen, but the problem is that the animation doesn't work outside of the pen.
elzi over 9 years

Looks like you found the problem yourself then... prefix-free is not being included correctly. Here's a direct link to the codepen output frame: view-source:s.codepen.io/boomerang/… View the source and use it as a reference to how your markup should look.
maudulus over 9 years

yes it is not. how do i include it correctly. I have followed the docs and it's all linked, including the jquery pluging, but not working.
CMS_95 over 9 years

You may need to use -moz- or -webkit- to do the animation in a regular browser window

Can you organize everything into a codepen so I can make edits?

Link me to a live page and I'd be happy to help further - but there's nothing left to debug at this point
maudulus over 9 years

The source doesn't seem to have anything there @elzi

Sorry - that link only works temporarily I realize. Try replacing your prefixfree.js with this: s.codepen.io/assets/libs/prefixfree.min.js
