Topic: Change mac address permanent

[cattledog]

Hi all want to change my wan mac address to a new one so my isp allows my connection but would like this to be permanent not revert back after reboot.

Cheers

yes I have searched but they are older versions of sme and not sure if this would apply to sme9x

and what are the result of your search ?

Nothing relevant for sme9...

Nothing relevant for sme9...

if it is related to any linux distro based on rpm ( or even any linux) , it might just need some adaptations we might be able to suggest.

cattledog: please give us the links to the topics you foud.. even if not SME9 related, they can be a good start point

please give us the results, thank you (I mean results from contribs.org first)

well this is totally adapted to SME !

for a temp change ( assuming your external network is eth0)

Code: [Select]

    /etc/init.d/networking stop
    ifconfig eth0 hw ether 02:01:02:03:04:08
    /etc/init.d/networking start
Execute "ifconfig eth0" to confirm.

then to get it permanent to reboot :

In Red Hat Enterprise Linux (RHEL) and other similar systems (Fedora, CentOS, etc.) an easy way to make changes "permanent" across reboots is to add an appropriate entry to the /etc/sysconfig/network-scripts/ifcfg-ethN file (ifcfg-eth0 for the first Ethernet interface config file, ifcfg-eth1 - for the second, etc.):

    MACADDR=12:34:56:78:90:ab

then for SME for making it permanent to reconfiguration, you will have to make it in a template

Code: [Select]

mkdir -p /etc/e-smith/templates-custom/etc/sysconfig/network-scripts/ifcfg-ethX/
vim /etc/e-smith/templates-custom/etc/sysconfig/network-scripts/ifcfg-ethX/10HWADDR

and add something like this

Code: [Select]

{
    $OUT = "";
    return if ($InternalInterface{Name} eq "bond0");
    return unless $THIS_DEVICE =~ /^eth[01]$/;
my
    my $MACaddr = $is_internal ?
        '':         $ExternalInterface{MACaddr};
return if $MACaddr  eq '';
    $OUT .= "MACADDR=$MACaddr " ;
}


then  do

Code: [Select]

config setprop ExternalInterface MACaddr 12:34:56:78:90:ab

test the template with

Code: [Select]

expand-template /etc/sysconfig/network-scripts/ifcfg-eth0
again assuming your actual external network is eth0 ( adapt to eth1 or anything else if it is different)

Warning NOT TESTED, there might be some typos

Yes...thank you.

I was thinking that it was going to help.

By the way I sent an email and it was intended for you Jean-Philippe Pialasse about the way you did this:

Does anybody has already to configure such connection directly in SME with the modem bridged ?? ( no login, no password, fixed IP, unknown gateway IP)

How did you handle it ?

It was something you did back in 2013...I was after instruction that you followed.

AFAICS in templates/etc/sysconfig/network-scripts/ifcfg-ethX/10HWADDR fragment, a

Code: [Select]

config setprop ExternalInterface HWAddress 12:34:56:78:90:ab

followed by proper action/event should be enough (and it is so at least since SME8)

this is OT in this topic and you already posted the same question elsewhere..

WRONG !!!!!!

HWAddress  is a totally different purpose : choosing the right network card based on their original MAC Address
MACADDR is to fake the MAC Adress !!!!

ops.. I misunderstood.. I apologize

ops.. I misunderstood.. I apologize

no problem, It took me also a time to see the difference
plus if you see the syntax of debian it does not help to see the difference
