There are 2 "inet"s in ifconfig

Hi

when I #ifconfig in Terminal, there are 2 inet entries:


One of them (inet 192.168.2.1) is redundant. How to get rid of it?

I know a command called networksetup with the -setmanual option, could that be used to remove the redundant inet?

ifconfig en3 192.168.2.1 -alias

That should remove it.

I've tried that but that seems to last only temporarily.

After some time has passed or after a restart the en3 's got the same 2 inets again, thanks.

Further info: The en3 interface is actually a USB-Ethernet device and I have once assigned it the IP address of 192.168.2.1 then changed it to 192.168.1.41. I did this for Internet Sharing, i.e. to share the Ethernet (en0) with USB-Ethernet device. Now, I've set up all interfaces to have 192.168.1.x IPs and so the en3 must have 192.168.1.x IP, but whenever I connect any device to en3, they cannot communicate because the en3 is assigned 192.168.2.1

This unwanted IP of 192.168.2.1 still comes up, how to get rid of it for good? Thanks.

Do you have Internet Sharing turned on? If so, I can guarantee that's where the second 'inet' is coming from.

If that's not it, I would suspect Parallels (or VMWare, or VirtualBox). Virtualization apps create virtual interfaces for routing internet to your VMs.

Yes it's turned on. But it's the basic goal anyway: To transmit the Ethernet connection (en0) to the USB-Ethernet device (en3)

If I do not turn it on, then it's not transmitted at all.

Here are further info: The Ethernet is connected to DSL modem and the DSL is in bridge mode and the Mac connects to the Internet using PPPoE connection, i.e. it's the Mac that initiates the Internet (PPPoE) connection and in this way, the Mac's got a WAN IP.

Then by Internet sharing I plan to distribute the Internet to my Laptops, so I employed a USB-Ethernet converter (en3) which is connected to a Wireless Access Point. The en3 is supposed to have the IP 192.168.1.41 and the WAP is IP 192.168.1.244.

A similar setup with Internet Sharing on has worked at the start, actually but then I had shared the Internet from 192.168.1.x to 192.168.2.x.

The problem is, the Internet Sharing insists on remembering the 192.168.2.x IP. If only I could clear that IP...

Maybe delete some plist values, such as: /Library/Preferences/SystemConfiguration/com.apple.network.identification.plist ?

To remove it you have to disable the sharing from preferences.
