Comment 2 for bug 1639630

Hello,

the short version: it works only after moving the enter-hook script one directory up.

The long version:

as my device is not set up for developer mode yet, I have tried replicating the changes by manually:

I left the line added to /etc/apparmor.d/sbin.dhclient in place:

phablet@ubuntu-phablet:/etc/apparmor.d$ diff -c /home/phablet/aether/sbin.dhclient.orig sbin.dhclient
*** /home/phablet/aether/sbin.dhclient.orig 2016-11-02 21:58:11.399360012 +0100
--- sbin.dhclient 2016-11-02 22:15:36.399360075 +0100

    # aethercast

+ /run/aethercast/dhclient*.leases lrw,

    # synce-hal
    /usr/share/synce-hal/dhclient.conf r,

I performed the following according to the merge diff:

* sudo mv /etc/dhcp/dhclient-enter-hooks.d/aethercast/dhclient-hook-p2p /etc/dhcp/dhclient-enter-hooks.d/aethercast
* sudo chmod 755 /etc/dhcp/dhclient-enter-hooks.d/aethercast/dhclient-hook-p2p

added the asterisk to leases:

After reboot, the M10 FHD on so changed OTA-13 connects successfully to a Microsoft Wireless Display Adapter.

On the first connect, I see no new default route added (checked by "ip r l").

But, after disconnecting and reconnecting, a default route appears:

$ ip r l
default via 192.168.157.1 dev p2p0
default via 192.168.1.254 dev wlan0 proto static metric 600
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.33 metric 600
192.168.7.0/24 dev p2p0 proto kernel scope link src 192.168.7.1
192.168.157.0/24 dev p2p0 proto kernel scope link src 192.168.157.100

It works multiple times without new default route only after moving the enter hook one directory up:

$ sudo mv /etc/dhcp/dhclient-enter-hooks.d/aethercast/dhclient-hook-p2p /etc/dhcp/dhclient-enter-hooks.d/

Could there be a restriction that dhclient does not look at the enter-hooks directory recursively?
