hm laptop doesn't get IP?
try dhcp (server?) 10.0.0.0 (give 10.0.0.201 to the PI)
Look to /etc/dhcp/dhcpd.conf
The important:
subnet 10.0.0.0 netmask 255.255.255.0 {
so it listens on 10.0.0.201
option domain-name "mysrv.world";
option domain-name-servers 10.0.0.201;
so the name are resolved by the bind of PI.
option routers 10.0.0.201
so it is the routers for the interface (we can use the PI as router!!!).

easy... 192.168.1.109 (connected).
to find the address:
nmap -sn 192.168.1.0/24
(doesn't help... well run it as root = better...)

Don't forget the firewall on the PI:

********* Getting tomcat running *********

yum install java should be ready for tomcat).
yum install java maven
git clone https://github.com/jfclere/tomcatPI
cd tomcatPI/demo
java -jar ./target/demo-1.0-SNAPSHOT-jar-with-dependencies.jar
Don't forget the firewall (again).
firewall-cmd --permanent --zone=FedoraServer --add-port=80/tcp
firewall-cmd --reload

******** Getting Astro Hat examples running ********

HAT: https://github.com/RPi-Distro/python-sense-hat
https://github.com/raspberrypi/hats
https://github.com/RPi-Distro/python-sense-hat (looks the good one...)
A lot needs to be install gcc/python-devel/gcc-gfortran/redhat-rpm-config (hard to guess this one!) and building takes ages...
libz-devel, jpeg-devel
testing... /root/python-sense-hat/examples
mssing https://github.com/RPi-Distro/RTIMULib cmake/gcc-c++
in RTIMULib/RTIMULi/build (mkdir ) cmake ... make make install.
in RTIMULib/Linux need qt-devel
in RTIMULib/Linux/python (probably the only one really needed!).
./python-sense-hat/examples/colour_cycle.py (works...)
./RTIMULib/Linux/build/RTIMULibCal/RTIMULibCal (to get the RTIMULib.ini to pur in /etc according to the doc).

********* Sending information to ActiveMQ and consuming it *******

yum install stomppy
install activemq on laptop
check stomp port:
INFO | Listening for connections at: stomp://jfcpc:61613?maximumConnections=1000&wireFormat.maxFrameSize=104857600
INFO | Connector stomp started
http://127.0.0.1:8161/admin/ (we receive something binary UTF8 encoded string).
write a STOMP logic to send message to ActiveMQ (running on my laptop)
https://github.com/jfclere/tomcatPI/tree/master/python
write a small jms client to consum the messages from the raspberry
https://github.com/jfclere/tomcatPI/tree/master/reader

After updating to fedora23 I noted I cant use ssh from my laptop to servers I use to connect it. I have got the weird message ssh -vvv:  
debug1: Roaming not allowed by server

Obviously it isn't a server problem, while try to understand I have found:
 https://www.gentoo.org/support/news-items/2015-08-13-openssh-weak-keys.html

Of course adding
PubkeyAcceptedKeyTypes=+ssh-dss
in .ssh/config helps
Checking the key shows that I need new key pairs soon:
-rw-------. 1 jfclere jfclere   736 Nov 22  2006 id_dsa
-rw-r--r--. 1 jfclere jfclere   619 Nov 22  2006 id_dsa.pub

I have being using the same keys for ~10 years in fact!!!
Well mostly only inside Red Hat vpn, time to change keys and spot the server I am using only from time to time...

It looks very easy now:
yum install libimobiledevice (really needed?)
dmesg tells:
+++
[ 3202.355929] ipheth 1-8.4:4.2: Apple iPhone USB Ethernet device attached
[ 3202.355982] usbcore: registered new interface driver ipheth
+++
In network manager I am able to confgure it but not to activate it (may be I have something wrong in my box).

Using dhclient wwan0
gets it working :D

Note that the iphone is running 4.2.1 and my provider is swisscom
