G1 : Advanced Networking Protocol Workshop

The main aim of this workshop is to realize a redundant network infrastructure to ensure maximum availability in case of a device or path failure. The architecture of the network is shown in the diagram given below.

Scope statement for the specific task

Task overview

We were assigned to configure one of the L3 switches to enable routing protocol(for IPv4 and IPv6) and also to ensure layer 3 redundancy with HSRP.

Materials used for the specific task

• Layer-3 Switch : Cisco Catalyst 3560-E
• PC with serial connection

Week 2 (05/10/2015)

• ssh pour la machine cordouan

ssh root@cordouan.insecserv.deule.net

• configuration de la machine virtuelle XEN

xen-create-image --hostname=WESTMALLE --ip=193.48.57.161 --netmask=255.255.255.240 --gateway=193.48.57.174 --nameserver=193.48.57.48 --dir=/usr/local/xen --genpass=0 \
--password=pasglop --dist=stable

• permet de la créer une fois le fichier de config

xl create /etc/xen/WESTMALLE.cfg

• emplacement fichier de configuration de la machine XEN

 /etc/XEN/WESTMALLE.cfg

Fichier:WESTMALLEcfg.txt
modification de la taille mémoire, et "bridge=IMA5sc"

• permet de lancer la machine virtuelle XEN

xl console WESTMALLE

Week 3 (12/10/2015)

This week we started with installing few important packages in the Xen virtual server such as apache2, fail2ban, bind9, dnsutils and openssh-server. To secure the ssh server, we changed the configuration line (as shown below) of the file /etc/ssh/sshd_config:

Port 619
PermitRootLogin no-password
