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.
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.
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)
- 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
- 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
- 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
Session 9 (03/12/2015)
- Configuration of the Radius server
- New client, VLAN and user
- PEAP encryption instead of MD5
- RAID5 configuration
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
