(Get the code!)
Hello, the silo 2162 installed nicely, but the update to aethercast did not
install. What has been changed is:
The following packages will be upgraded:
isc-dhcp-client isc-dhcp-common isc-dhcp-server
I see the changed /etc/apparmor.
But I still see
/etc/dhcp/
this will only work when pushed a directory higher, as explored below.
In the current state, I can connect once to the Wireless Display Adapter while
conserving internet access. By the second time, internet access is dropped.
The behavior I'm seeing is that at the first time, a new network is added,
albeit without a default route. By the second connection, a new network is
added, this time with a default route.
=== network routes with silo 2162 installed:
$ dpkg -l | egrep '(aethercast|
ii aethercast 0.1+15.
ii aethercast-tools 0.1+15.
ii isc-dhcp-client 4.3.1-5ubuntu2.
ii isc-dhcp-common 4.3.1-5ubuntu2.
ii isc-dhcp-server 4.3.1-5ubuntu2.
before aethercast:
$ ip r l
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
after first aethercast connection, it being active:
$ ip r l
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
after second aethercast connection, it being active:
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
This stays the same from here on, even after disabling external display via
menu. Disabling and reenabling wireless network completely re-empties the
routes, eliminating the default route via the p2p0 device, thus restoring
internet connectivity. Until aethercast is activated again.
It seems that p2p0 connections are not torn down on terminating aethercast
connection, at least after the first time - when using it multiple times, I
always end up with two networks routed via p2p0, at the second time coming with
a default route. I do not know what is the desired behavior, if networks are
supposed to be torn down after ending an aethercast connection.
==== network state after moving the aethercast dhclient-enter-hook up by one
directory and rebooting:
$ sudo mount -o rw,remount /
$ sudo mv /etc/dhcp/
$ sudo shutdown -r now
before first connection:
$ ip r l
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
after first aethercast connection, it being active:
$ ip r l
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
after second and third aethercast connection, it being active:
$ ip r l
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
The two p2p0 networks created remain, but the default route via p2p0 is not not
added, allowing undisturbed internet access to the device.
If there has been a change to the aethercast package in silo 2162, it is not
appearing when deploying the silo.
What is missing from my point of view is to move the dhcpclient-
directory up, I assume the enter-hook.
dhcp client.
@Simon: Could you please revisit that and tell me when I can test that again? I
am now familiar with where to install bileto :-)
