Specification of the specific task

Presentation of the particular task

The specific task consist in configuring one of the two wifi access point (AP). Those APs are connected to the Cisco Catalyst 6009 switches to provide further redundancy.

Hardware used for the particular task

We use a Cisco Aironet 2600 wifi access point.

Cisco Aironet 2600 access point

Progress monitoring

Session 1 (01/10/2015)

Steps to follow :

Connecting via serial link to the Cisco Aironet 2600
Adapting the configuration for insecure network
Accessing the hotspot via ethernet
Using the web interface to configure mac address filtering

Session 2 (08/10/2015)

Configuration of the Wifi AP

minicom -os //9600 bauds

en

config

interface BVI 1

ip address 172.26.79.11 255.255.240.0

end

write

Using the web interface to configure mac address filtering (root:Cisco)
Different tests to enable mac filtering
- Unknown problem that lead to the reset of the Access point

Session 3 (15/10/2015)

Reset of the Access point
Mac address filtering working correctly
Creation of the AP (SSID = "troubadour")
Filtering half of the eeePC
Penetration test by MAC spoof from an eeePC :

ifconfig wlan0 hw ether XX:XX:XX:XX:XX:XX

Session 4 (22/10/2015)

Creation of the virtual drives
Configuration of the xen virtual machine "troubadour"

xen-create-image --hostname=troubadour --ip=193.48.57.165 --netmask=255.255.255.240 --gateway=193.48.57.174 --dir=/usr/local/xen 
--mirror=http://debian.polytech-lille.fr/debian/ --dist=jessie --passwd

Session 5 (12/11/2015)

Successful wifi WEP encryption crack
SSH accessibility of the VM.

WEP Encryption crack

Session 6 (19/11/2015)

Wifi WPA encryption crack attempt almost successful
Cap file & handshake captured
dictionnary created with the powerful command crunch:

crunch 8 8 -o wl.txt -t %%%%%%%%

Problems with apt-get to download aircrack on tutur

Session 7 (25/11/2015)

Crack of the WPA key

Aircrack of the previously captured cap file
Successful WPA crack
Configuration of the wifi hotspot for the local network

ip default-gateway 10.10.10.254

Telnet accessibility from a VM
Configuration of the DNS server following this tutorial
Beginning of SSL configuration while Gandi processes the DNS change

DNS analyse by digicert.com

Successful DNS configuration :

Session 8 (26/11/2015)

End of SSL certification following this tutorial
Fixing a conflict in /etc/apache2/ports.conf
- Apache2 would not restart because of an already-listened-to 443 port
- The port 443 was listened by a previous module
- All other modules listenning to 443 port were commented out
Successful SSL configuration for www.troubadour.lol and troubadour.lol

Firefox is happy, the connexion is secured

Fixing a bug on the IPv6 address, causing the DNSSEC to fail
- TCP and UDP transit didn't seem to work
- Port 53 seemed closed (according to zonemaster.com)
- A correct rebuild of Bind worked

Results on the different test of zonemaster.com

Session 9 (03/12/2015)

RAID5 configuration

Configuration of the Radius server
- New client, VLAN and user
- PEAP encryption instead of MD5
RAID5 configuration

WiFi interface connected to our hotspot

Session 10 (04/01/2016)

Correction of errors on the raid5 drives
- The drive mount sequence was wrong (Automatic mount of an non-existent raid drive)
- Removing the mdadm deamon solved the problem
- Only downside : the raid has to be configured on each reboot
- Automatic "md127" appears

mdadm --stop /dev/md127
[   37.984366] md: md127 stopped.
[   37.984382] md: unbind<xvdf>
[   37.984388] md: export_rdev(xvdf)
[   37.984420] md: unbind<xvdd>
[   37.984425] md: export_rdev(xvdd)
mdadm: stopped /dev/md127

This commands are mandatory for a correct detection of our raid on md0
Test with a file on the raid
- Even with one disk less (here xvde) we can mount the raid and see its content

Successful test of the RAID5 drives
