Title: NetworkManager interferes with unmanaged 802.11 monitor mode interfaces Status in network-manager package in Ubuntu: Invalid Bug description: If a virtual 802.11 interface of type monitor is created on a 802.11 physical interface that already has a virtual interface of type managed created on it, then the managed interface is deleted. NetworkManager sets the type of the monitor interface to managed. This can be illustrated by the following commands. All the interface names have been listed in /etc/network/interfaces as follows so NetworkManager should not be managing them in any way. # Disable network manager on interface names I want to use for monitoring # related purposes iface eth1 inet manual iface BigTenda inet manual iface LittleBelkin inet manual iface LittleTenda inet manual iface Sinmax inet manual iface mon0 inet manual iface phy0.mon manual iface phy1.mon manual iface phy2.mon manual iface phy3.mon manual iface phy4.mon manual iface phy5.mon manual iface phy6.mon manual iface phy7.mon manual iface phy8.mon manual iface phy9.mon manual root@dragon:/home/roger# systemctl start NetworkManager root@dragon:/home/roger# iw dev phy#3 Interface Sinmax ifindex 11 wdev 0x300000001 addr 00:0f:11:92:06:b2 type managed root@dragon:/home/roger# iw phy phy3 interface add phy2.mon type monitor flags otherbss root@dragon:/home/roger# iw dev phy#3 Interface phy2.mon ifindex 12 wdev 0x300000002 addr 00:0f:11:92:06:b2 type monitor Interface Sinmax ifindex 11 wdev 0x300000001 addr 00:0f:11:92:06:b2 type managed root@dragon:/home/roger# iw dev Sinmax del root@dragon:/home/roger# iw dev phy#3 Interface phy2.mon ifindex 12 wdev 0x300000002 addr 00:0f:11:92:06:b2 type managed root@dragon:/home/roger# systemctl stop NetworkManager root@dragon:/home/roger# iw dev phy#3 Interface phy2.mon ifindex 12 wdev 0x300000002 addr 00:0f:11:92:06:b2 type managed root@dragon:/home/roger# # Unplug the netwaork adapter for a few seconds root@dragon:/home/roger# iw dev phy#4 Interface Sinmax ifindex 13 wdev 0x400000001 addr 00:0f:11:92:06:b2 type managed root@dragon:/home/roger# iw phy phy4 interface add phy2.mon type monitor flags otherbss root@dragon:/home/roger# iw dev phy#4 Interface phy2.mon ifindex 14 wdev 0x400000002 addr 00:0f:11:92:06:b2 type monitor Interface Sinmax ifindex 13 wdev 0x400000001 addr 00:0f:11:92:06:b2 type managed root@dragon:/home/roger# iw dev Sinmax del root@dragon:/home/roger# iw dev phy#4 Interface phy2.mon ifindex 14 wdev 0x400000002 addr 00:0f:11:92:06:b2 type monitor This stops any running or future network traces on this interface working. This is another example of network manager interfering with interfaces it is not supposed to be managing. See bug #1314848 which is still unresolved.
