When I issue "ifconfig" command in Terminal, it does not give the IP address of the network interface. I use Ethernet connection for the Mac Pro (late 2013). However, the output of ifconfig does not show the IP address.
Is there anything I should know about using ifconfig command in Terminal? Thanks.
Mac Pro (Late 2013), OS X Mavericks (10.9.3)
Thanks. But I am not sure if my question is clear to you. The Mac is connected through Ethernet as I stated. I want to show the inet address. Ifconfig should show the IP addresses of all the interfaces.
The ifconfig command works for me in Linux. But somehow it does not work in Mac. Hopefully, my question is clear.
Perfectly clear, but not clear that you are certain you have an internet connection. You can use an interface normally, but not be connected at the moment you ran the command.
If I run it on mine, all interfaces are displayed. Those with a connection have inet addresses. Those not connected have no inet fields.
If it is being hidden for some reason, you might find the why in the man page.
I am using that Mac machine now and it is connected via an Ethernet interface. I can ping the default gateway ok. But when I issue ifconfig, I don't see eth0 or eth1.
What interface name should be displayed in Mac for Ethernet connection?
In the output of ifconfig, I see lo0:, gif0:, stf0:, en1:, en2, etc. Just no eth0 or eth 1....

I just don't think it must be en0, en1. The OS can define it however it needs. I don't know why you don't have en0.
I don't believe it is defined to be this way, but en0 on mine is Ethernet. en1 is WiFi. I don't think there is a requirement for it to be 0 and 1. Does 1 and 2 have addresses? Do the MACs match?
It will not show the address if it is not connected. The addresses are listed as inet6 and inet.
I'm not sure if there is an option to disable showing the address, but you might find it in
man ifconfig

According to this hint, it may be that you previously had another ethernet interface that was deleted.

It is also possible that your Mac Pro has multiple Ethernet ports, and the one you are using is en1
