openSUSE; disable ifup networkmanager checking

openSUSE; disable ifup networkmanager checking

So you are running KVM or maybe you just want to run some fancy networking beyond what networkmanager can do in openSUSE then you have noticed that you get a message similar to the below.

# ifup virbr1.300

Network is managed by 'NetworkManager.service' -> skipping

Sad, Sad. Some other Linux distributions don't do this kind of checking, but i guess that leaves open some

holes there especially if you don't know what your doing. Pat on the back for SUSE in making things more secure here.

So you think your an expert. Then look no further.

To disable the networkmanager checking in openSUSE 12.3 use the following:

1) make a backup copy of /sbin/ifup

2) open /sbin/ifup for editing

3) Find the following lines:

###############################################################

# Check if /etc/init.d/network (network.service) is enabled, otherwise

# (masked by e.g. the NetworkManager.service) inform the user and exit.

#

network_service_id=`get_network_service_id`

if [ "x$network_service_id" != "xnetwork.service" ] ; then

mesg "Network is managed by '$network_service_id' -> skipping"

exit $R_NOTIMPL

fi

case $SCRIPTNAME in

ifup)

# start everything in network service cgroup

if ! in_network_service_cgroup ; then

add_to_network_service_cgroup

fi

;;

esac

4) Modify the following lines by commenting them out like below:

###############################################################

# Check if /etc/init.d/network (network.service) is enabled, otherwise

# (masked by e.g. the NetworkManager.service) inform the user and exit.

#

network_service_id=`get_network_service_id`

#if [ "x$network_service_id" != "xnetwork.service" ] ; then

# mesg "Network is managed by '$network_service_id' -> skipping"

# exit $R_NOTIMPL

#fi

case $SCRIPTNAME in

ifup)

# start everything in network service cgroup

if ! in_network_service_cgroup ; then

add_to_network_service_cgroup

fi

;;

esac

You are now able to execute ifup without any networkmanager checking in openSUSE 12.3.

To disable the networkmanager checking in openSUSE 12.2 use the following:

1) make a backup copy of /sbin/ifup

2) open /sbin/ifup for editing

3) Find the following lines:

# Check if NetworkManager is running, inform the user and exit

#

if [ "$NETWORKMANAGER" = yes ] && ! netcontrol_running ; then

if [ "$SCRIPTNAME" != ifdown -a "$INTERFACE" != lo ] ; then

mesg "Network interface is managed by the NetworkManager ->

skipping"

exit $R_NOTIMPL

fi

elif nm_running && [ "$INTERFACE" != lo ] ; then

mesg "Network interface is managed by the NetworkManager -> skipping"

exit $R_NOTIMPL

fi

4) Modify the following lines by commenting them out like below:

# Check if NetworkManager is running, inform the user and exit

#

#if [ "$NETWORKMANAGER" = yes ] && ! netcontrol_running ; then

#if [ "$SCRIPTNAME" != ifdown -a "$INTERFACE" != lo ] ; then

#mesg "Network interface is managed by the NetworkManager -> skipping"

# exit $R_NOTIMPL

#fi

#elif nm_running && [ "$INTERFACE" != lo ] ; then

# mesg "Network interface is managed by the NetworkManager -> skipping"

# exit $R_NOTIMPL

#fi

You are now able to execute ifup without any networkmanager checking in openSUSE 12.2
