; Criar pastas para armazenar os dados:

# mkdir /opt/dynagen
# mkdir /opt/images

; Descompactar IOS

# unzip -p c7200-advipservicesk9-mz.124-9.T.bin > c7200.bin

; Verificar

# file c7200.bin

; Mover

# mv c7200.bin /opt/images

; baixar dynamips

# wget http://www.ipflow.utc.fr/dynamips/dynamips-0.2.7-RC3-x86.bin

# mv dynamips-0.2.7-RC3-x86.bin /opt/dynagen/dynamips

# chmod 755 /opt/dynagen/dynamips

# ln -sf /opt/dynagen/dynamips /usr/bin/dynamips

; baixar dynagen

# wget http://ufpr.dl.sourceforge.net/sourceforge/dyna-gen/dynagen-0.9.2.tar.gz

# tar -xvzf dynagen-0.9.2.tar.gz

# mv dynagen-0.9.2/* /opt/dynagen/

# chmod 755 /opt/dynagen/dynagen

# ln -sf /opt/dynagen/dynagen /usr/bin/dynagen

; instalar libpcap para captura de pacotes

# apt-get install libpcap0.8

; Criar um arquivo de configuracao:

# vi simple1.net

#Simple lab

[localhost]

[[7200]]

image = /opt/images/c7200.bin

npe = npe-400

ram = 160

[[ROUTER R1]]

s1/0 = R2 s1/0

[[Router R2]]

; Iniciar servidor Dynamips em background:

# dynamips -H 7200 &

; Iniciar dynagen

# dynagen -d simple1.net

; Vai iniciar o dynagen

=> list

; Acessar roteadores via telnet:

# telnet localhost 2000

# telnet localhost 2001

; ou, dentro do dynagen:

> telnet R1

> telnet R2

...

e assim por diante ...

;#########################################################
; Identificar idle-pc
;#########################################################

; Criar um arquivo de configuração para instanciar apenas 1 router:

# vi idle.net

# Detectar idle

[localhost]

[[7200]]

image = /opt/images/c7200.bin

npe = npe-400

ram = 160

[[ROUTER R1]]

; Parar servidor dynamips caso esteja rodando,
; e iniciar outro:

# dynamips -H 7200 &

; Iniciar dynagen

# dynagen -d idle.net

; Vai iniciar o dynagen

=> list

; Acessar por telnet um router,
; até o prompt de usuario:

# telnet localhost 2000

Router>

; Voltar ao dynagen e verificar idle-pc

> idlepc get R1

;#########################################################
; Dynamips em maquinas separadas
;#########################################################

; Instalar dynagem e baixar IOS em cada Maquina

; Exemplo de arquivo de configuração:

# vi 3routers.net

[10.101.5.15:7200]
[[7200]]
image = /opt/images/c7200.bin
ram = 160
idlepc = 0x624a11f8
[[ROUTER R1]]
s1/0 = R2 s1/0

[10.101.5.16:7200]
[[7200]]
image = /opt/images/c7200.bin
ram = 160
idlepc = 0x624a11f8
[[ROUTER R2]]
s1/1 = R3 s1/0

[10.101.5.17:7200]
[[7200]]
image = /opt/images/c7200.bin
ram = 160
idlepc = 0x624a11f8
[[ROUTER R3]]

# dynagen -d 3routers.net
