Ghost Ethernet Adaptor (en2) appeared in all network configurations!

Since a few minutes, for no related reason I can imagine,
I find in all my network configurations a new Network Port:
Ethernet Adaptor (en2)
Worse than this, in all the configurations I have not
recently modified, I found that this new ghost interface
is "On".
I looked at what may have happened at the Unix level to
discover that I have a new interface named en2 which has
an Ethernet address that start like the one of my internet
Ethernet card, but which is different.
Where is this ghost "Ethernet Adaptor" coming from?

This date correspond exactly to the instant I used
the Bluetooth System Preferences to define a new

But there was no Ethernet involved at any time in this
configuration.
This property list does contain a complete en2
interface description (sorry I can't quote the

  • Ghostly ethernet adaptor

    My home wireless network (previously stable for over a year) keeps dropping the connection to the powerbook after 10-15 seconds. When I opened the network bit of system preferences it told me that a new 'ethernet adaptor (en3)' had been detected, but I don't have anything new plugged in. A box appeared that said I should verify the adaptor settings then press OK, but unless I pressed OK I could do nothing else. I pressed it. Rebooting laptop and router does not help and the PCs in the house connect to the router OK both via ethernet and wireless.
    The only recent changes are that I have recently joined .mac and the only new software is backup 3.
    I don't seem to be able to remove the ethernet (en3) and can only presume that something has gone wrong for it to be detected in the first place.
    Any suggestions?
    Mike

    I'm going to guess that you are running Parallels? (If not I have no idea)
    If you are they are basically clones of your Ethernet port. En3 is the port windows sees and uses, and En2 is a bridge between that port and the physical port in your computer that OS X uses.
    Interesting side effect of it is that Parallels doesn't use the same MAC address as OS X. So if for some reason you MAC is blocked on a network, you can still access the same net work if you boot windows in Parallels. I've been on bandwidth restricted networks and had my MAC address locked before and switching to windows in Parallels always give me access back. Its also kind of amusing because each boot or parallels gives you a new MAC address.

  • Thunderbolt to Ethernet adaptor no longer works

    Hi All,
    After upgrading to Maverick I find my Thunderbolt to Ethernet adaptor no longer works. Network app insists the cable isn't connected but the cable works fine with other pcs (a Raspberry Pi for instance).  Any suggestions?
    R.

    If you have access to the Companies Intranet then the Ethernet connection is working just fine. The computer is getting a valid IP address from the companies DHCP server.
    You need to take this up with the IT staff as it seems whatever IP your computer is getting it is being block from going out to the internet.

  • What is the ETHERNET ADAPTOR?

    I have switched to running my internet desktop Intel iMac with wireless. I was using an ethernet cable. That cable is now disconnected and it shows up in the network preference as disconnected. However in the network preference the "ethernet adaptor (en2)" shows active. What is the ethernet adaptor, why is it active and what does it do? Thanks.

    Are you running parallels or the equivalent because that creates virtual network devices to trick windows into sharing the network with OS X.

  • I have heard that if I load WIN8 on my PC,the Network Ethernet adaptor driver will need updating?

    My PC is a Presario CQ5302,I have WIN 8 installed,failure to connect to Internet produces error message from Windows informing me there is a problem with Ethernet adaptor,it then asks if it should fix problem,after agreeing it does this and all is OK until the next time I switch on,I then have to repeat all over agin !!
    Is HP likely to upgrade the driver for this unit anytime soon?
    This question was solved.

    Hi:
    I just checked the Realtek site and they don't have any windows 8 drivers for the network adapter that is in your PC released  yet.
    My understanding is that no drivers will be available until October 26th at the earliest, which is the date that Windows 8 will be available for sale.
    You may want to see if the Realtek W7 driver works better for you as it is probably newer than the one you have.
    4th one down on the list is the auto-install file.

  • USB vs Firewire Ethernet adaptor and impact on network speeds

    So my wife is going to be taking some online classes and wants to backup the wireless by connecting to our router via ethernet given that we've had some issues with our cordless phone interuppting our wireless signal. She's concerned about network speed since classes involve streaming video and being connected via webcam. I know Firewire is faster for transfering information in general...say to an external hard drive...does the same go for internet speed? Will internet speed be slowed should she opt for a USB ethernet adaptor versus Firewire?

    The transfer speed will be governed by the slowest link in the chain.  Fire wire theoretically is twice as fast as USB 2.
    Ciao.

  • I have connected my time capsule to motorola SG6580 modem via ethernet.  I have a wireless network on the motorola and a wireless network from the time capsule.  I get duplicate IPs error messages sometimes. How do I fix?

    I have connected my time capsule to motorola SG6580 modem via ethernet.  I have a wireless network on the motorola and a wireless network from the time capsule.  I get duplicate IPs error messages (no connection) sometimes when trying to connect devices to the wireless network. How do I fix? Sometimes devices cannot connect to the network because of conflicting IPs.  I look on the Motorola and every device has a unique IP assigned but occasionally a device has taken the IP of another device.  I have been writing down all the devices and the IPs they have been using.  It happens more with PCs than Macs, ipads or iPhones.

    If the Time Capsule is set up correctly in bridge mode, then it is the responsibility of the Motorola modem/router to provide the correct IP address assignments for all devices on the network.
    Check to insure that the Time Capsule is correctly set up to operate in bridge mode as follows:
    On your Mac, open AirPort Utility
    Finder > Applications > Utilities > AirPort Utility
    Click on the Time Capsule icon, then click Edit in the smaller window that appears
    Click the Network tab at the top of the next window
    Insure that the setting for Router Mode is configured to read "Off (Bridge Mode)"
    Once you have confirmed that the Time Capsule is configured correctly, everything else is the responsibility of the Motorola modem/router as far as network routing and IP address assignments for devices.
    If you continue to have IP address issues, then you should contact the Internet Service Provider (ISP) that provided the Motorola device to you and ask them to fix the issue.

  • Can the Gigabit Ethernet LAN Port be used with a Thunderbolt to Gigabit Ethernet adaptor and then to a Thunderbolt Hard Drive as a back up drive?

    Can the Gigabit Ethernet LAN Port be used with a Thunderbolt to Gigabit Ethernet adaptor and then to a Thunderbolt Hard Drive as a back up drive?

    If you use ethernet to connect the two AirPort Extremes together, you'll have Gigabit speeds available at all of the ethernet ports on both routers.
    If you connect the second AirPort Extreme using wireless only and configure the Extreme to "extend a wireless network", then the maximum speeds that the second router can attain will be limited to the capability of the wireless connection. So, if you connect at normal "n" wireless speeds of say 130 Mbps, that will be the maximum speed available at the ethernet ports on the second AirPort Extreme.
    I think you can easily see the difference between Gigabit ethernet, which is 1000 Mbps compared to "n" wireless at 130 Mbps. Even if you can manage to connect at 5 GHz speeds for wireless, the max speed will be in the 300 Mbps range, more than 3 times slower than Gigabit ethernet. Normal "n" speeds will be about 7 times slower than ethernet.
    For streaming high definition video and other demanding sources, you'll need as much bandwidth (speed) as you can get. Ethernet is always the best choice if you can possibly use it. And...there's no wireless interference on an ethernet connection.

  • Malware and Ethernet Adaptor

    Hello:
    It seems I might have some kind of trojan on my MacBookPro, since when I enter a particular site it redirects me to fling.com. It happens with both, Safari and Camino. I tried using ClamAV and MacScan but they do not detect anything.
    I am looking at the Network Status on System Preferences, and it lists AirPort, which is correct, but there are 2 Ethernet Adaptors, one follow by (en2) and the other by (en2), and both with IP addresses (10.37.129.2 and 10.211.55.2).
    Are those settings correct?
    Thanks for any help.

    I doubt the trojan. Sex sites are notorious for doing what you describe.

  • Sharing one ethernet cable with two macs using a USB Ethernet Adaptor

    I have two computers running Mac OS 10.6 but only one ethernet cable in my office. One ethernet cable goes from the wall to Mac #1. I have a cisco USB Ethernet Adaptor USB300M that I like to use as OUTGOING ethernet cable from Mac #1 to plug into Mac #2. Does anybody know how this works? Simply plugging it in does not work. Thanks for any suggestions!

    If either of these computers is a Mac Pro (65 lb.) tower, all of which have two Ethernet jacks, Internet sharing is crisply supported with any additional Hardware. Cable the wall jack Ethernet to the first Ethernet port, then cable the second Ethernet port to the second Mac. Configuration is described in this article:

  • Lion Server: All network users have disappeared

    Hi,
    A search through the forums and kbase didn't give me anything that mapped well to my problem. Here's the situation:
    Specs:
    Mac Pro (2008) 6GB RAM, SSD boot with space available, OS X Lion (latest) with Server.app
    Services:
    File Sharing
    Users: less than 15—accounts only used for file server access.
    This is the only server on the local network, all network routing is taken care of by a Meraki router.
    I went to add a new user to our fileserver, and was unable to connect to the server over Apple Remote Desktop. At the time, file sharing from the server (I *believe*) was still working. I logged in with the file server's local admin account via SSH and tried to use Kickstart to get ARD running again—something I'm well versed in. The script ran as usual, but ARD could still not connect. So, as everyone was in a meeting, I tried to use `shutdown` to reboot the fileserver from the CLI, something I've also done in the past (but not frequently). Usually that takes about a minute to work, and then my shell disconnects—but after 5 minutes, the Mac had not rebooted.
    At that point, I decided to walk to the server and manually force it down by holding the power button in. That powered off the Mac, and 30 seconds later, I booted it up.
    Back on my Mac via ARD, I was able to remotely control it and got to the Fileserver's log in screen, which featured a red dot in the use field I'd never seen before. It's tool tip read "network users are currently unavailable" (paraphrased, perhaps). I logged in with the Fileserver's local admin user (as usual) and launched the Server.app, only to find that in the `Users` section, there were no users listed, and the plus and minus buttons were greyed out.
    I tried rebooting but got the same results. I then repaired permissions and verified the boot drive. Lots of permissions repairs (as usual) but nothing improved. Another reboot after the permission repair and disk repair, just for safety's sakes… and as you can guess by me posting here… no improvement.
    I'm not heavily versed in Server. I'm not even sure if those users are stored in a database, and where that DB would live. Does server make dumps or backups of the users on its own? Should I have been? Is this LDAP? Anyone have some next steps I can try? What info would be useful?
    My first goal would be to recover a damaged DB. I only have just under 15 users, so re-creation isn't difficult. But, under the department of "I don't know a ton about Lion Server" I don't know if network users act like OS X users… where you could create a new user with the same username, but if their UID is different, then they won't have access to their owned files on the fileserver… is Server that exacting? Does it care who owns the file?
    Thanks in advance for any ideas, or resources you can point me to!

    It gets far weirder……
    Now no one, myself included can log in.

  • Custom NFS share point directory showing up on all network machines

    Hi,
    I'm in the process of migrating our 10.4 PowerMac server to a Mac Pro (running 10.5). I've been trying to recreate our 10.4 server setup as much as possible and so far I've only come across one annoying issue.
    We have fink installed on the server and under our 10.4 setup the /sw directory was set up as an NFS automounted share point with a custom mount point of '/sw'. I.e. users logging into client machines saw a /sw directory and could work with that. This made it easier to add fink packages as I only needed to do this on one machine (the server). This setup worked very well under 10.4 and had been working stably for the last couple of years.
    As we now have (for another month or two at least) a mix of intel and Power PC machines, I don't want to share out the (intel) server version of fink to all clients. In Server Admin, I have chosen to set the NFS protocol options to specify the IP address of just one client (an intel machine). I am only using NFS to share this directory. The plan is to add more client IP addresses as we get more intel machines.
    This works for the one intel client machine. Logging in via the GUI or via ssh allows you to run programs located under the /sw directory. The problem is that a phantom /sw directory appears on all client machines, even though their IP addresses are not specified in Server Admin. The /sw directory has root/wheel permissions (for user/group) and attempting to list its contents returns 'Operation not permitted' (even with 'sudo ls /sw').
    If I use Directory Utility to remove the connection to the Directory server on our main server, then the /sw directory becomes owned by root/admin and I can remove it (it appears empty). Reconnecting to the Directory Server changes the permissions back to root/wheel. It is also worth noting that when I first installed fink on the server (in /sw) the act of making this a share point also changed the permissions on /sw to root/wheel meaning that I couldn't access the fink programs that I had only just installed (this forced me to reinstall fink in /Volumes/Data/fink).
    Has anyone else noticed this behavior? It almost seems like Server Admin is not honoring the list of IP addresses that are being listed as targets for client machines. I had planned to install fink locally on the PowerPC clients until we upgrade them to intel machines. However, I would then also have to install fink somewhere other than /sw as I can't write to that directory. I would presume that this behavior should happen on any NFS share point that is trying to automount to a custom mount point on a client. Can anyone else verify this?
    Regards,
    Keith

    As a footnote. I have now removed my shared fink installation. It is no longer listed as an NFS sharepoint in Server Admin and running the 'showmount -e' command does not list it. However, a /sw directory is still being created on the server and on the client machines on our network.
    This is perplexing and frustrating. There is no sharepoint any more. I rebooted the server but it makes no difference. I removed the /sw directory (on the server) by booting the machine in target firewire mode and removing it by using a 2nd machine. But following the restart, it appeared again.
    This suggests that once you make any custom mountpoint (using NFS sharing) then you will forever be stuck with a directory at the root level of all your clients which you can not remove.

  • What can I migrate from my 13" MacBook (white 2007) to a new MacBook Air 13" using an ethernet cable and a USB ethernet adaptor for the MBA?

    I have, on order, a 13" MacBook Air (128Gb) and intend using Migration Assistant to transfer data from my 4 year old MacBook 13" (White) on set up.
    I have ordered an Apple USB Ethernet adaptor and have today purchased an Ethernet cable.
    I will want to transfer;
    Mail........Mailboxes, their contents and account settings. In fact the lot except the application itself.
    Safari..... Bookmarks, Cookies, Saved Passwords etc. As above
    Google Chrome.........same
    Address Book
    iCal
    iTunes
    iPhoto
    Documents. Excel, Word, Powerpoint & pdf's (a clean install of Office for Mac 2011 will take place on the MBA)
    MacBook and applications are currently up to date and I've read about disabling the energy saver to sleep option.
    Is it all that simple or am I missing something?
    Can Account Information in Mail be migrated?
    Will saved links be transferred in Safari (especially that of my ISP's customer area)? You have no idea what navigating around Orange France is like !
    Sorry if I sound a little naïve but I'm English, retired and living in France and the nearest Apple Store is a 3 hour drive away so I'm doing it all myself.
    Thanks
    Richard

    Use Setup Assistant when your new Mac first starts up.  See Using Setup Assistant on Lion (it's a bit more complete).
    Unless you choose to omit things, that will set your new Mac up exactly like the old one, except for a few preferences, etc., that may be different for the different hardware.  
    If your old Mac isn't running Lion, there will be some other differences, too.  See Changes in Lion from Snow Leopard.
