Thread: Possible to have Ethernet on Traditional but Wi-Fi on NetworkManager?

    Default Possible to have Ethernet on Traditional but Wi-Fi on NetworkManager?

    Hello!

    I have a laptop with a wired Ethernet connection and also a Wi-Fi connection.

    I'm running OpenSUSE 11.4, 64-bit. Both Ethernet and Wi-Fi have good drivers and get successfully online.

    In the network setup, I'm given a choice between Traditional and NetworkManager. Traditional is great for making sure things get started without having to log in, such as network services. NetworkManager is great for being flexible when actively using the laptop.

    Problem is, I would like to have the best of both. I'd love it if I could have the wired Ethernet be managed by Traditional, because I'd like it to always get online, without having to be nudged along. I often access my laptop remotely, so it's important for it to be up and reachable remotely, without having to log in first. However, that limits me to a single Wi-Fi network. It's awkward to change to somebody else's network, such as transferring between work and home. Ideally, I'd have a way for the Wi-Fi to be ran by NetworkManager, but leaving the wired Ethernet untouched by NetworkManager, so it's free to be managed by Traditional.

    Is this possible?

    Thanks!

    > I'm running OpenSUSE 11.4

    openSUSE 11.4 went past its end-of-life on 5 Nov 2012
    http://en.opensuse.org/Lifetime and therefore has received
    none of the (several) security patches and updates released since that
    date to rectify *known* (and publically available) security
    vulnerabilities..

    therefore, you should do one of these things as soon as possible:

    - cease connecting to any potentially insecure network (such as the
    internet)

    - move up to a currently supported operating system such as openSUSE
    12.1 or 12.2

    - join your fully patched openSUSE 11.4 to project Evergreen
    http://tinyurl.com/4aflkpy which will continue to provide
    security patches/updates until July 2014.


    of course, the sufficiency and capacity of security measures external to
    the operating system itself (such as an external NATing router, external
    firewall hardware, etc etc) *may* give you level of security you are
    happy with....but, be careful because there are black hats who know how
    to exploit known weak points.

    sorry, i have no input on the actual problem/symptoms you describe..

    Good advice to upgrade for better network security. I'm behind several layers of firewalls, so while prudent to upgrade, it isn't urgent for me yet. I'm sticking with OpenSUSE 11.4, because I rather like GNOME 2 and really don't like GNOME 3.

    Do you know if it's possible to designate a particular interface (such as wired Ethernet) so that it is capable of getting itself up and running without waiting for a user to log in? NetworkManager seems to require this, so I've had to set it to Traditional in order to get Ethernet up and running for my network services at boot. Is there a fix for this in OpenSUSE 12.2? That would give a reason to upgrade.

    Thanks!

    Then make sure that you switch to evergreen repos.

    In 11.4 you can use system profiles with scpm. You install it, then
    create a profile for "fixed" networking, and another for "wifi"
    networking. You switch using the command:

    Code:
    scpm switch fixed
    and then go to yast network module and define the correct settings for
    your wired connection. When you have it working, switch to "wifi"
    profile and go to yast again, say you want networkmanager, and configure
    it completely.

    You can go from one profile to the other, and you will see how it saves
    all modified configuration files, restores the backup of the new
    profile, and restarts the appropriate services with changed
    configuration files.

    That is what I do with my laptop, and it is one reason I do not upgrade
    from 11.4 on that machine. I have not tried scpm in 12.1, but I very
    much doubt that it can work with systemd.


    Notice that having both wired and wifi network makes no sense, and that
    you can not have both ifup and networkmanager at the same time.

    Nice, just set up the Evergreen repository now.

    Interesting idea to switch profiles, however, I was looking for a solution that would minimize having to manually administer things whenever switching back and forth between wired and wireless. Glad to know about the profile switcher, though. I didn't know such a program existed.

    Probably the best long-term solution is to upgrade to 12.2 and pick up the fixes to NetworkManager in there. However, that would mean giving up GNOME 2. I'll have to see which is the lesser pain....

    Yes, and it had a yast module that I think was abandoned. There was
    support to choose profile on boot, but I don't know if it works and how.

    It is not only about network, it detects many configuration files, like
    for example postfix.

    It is what I use in my laptop.

    In my desktop I had to ditch 11.4 and I have 12.1 with xfce. I also can
    not stand gnome 3, and not happy about systemd either...
