SETTING SSH DI ROUTER CISCO

 

Kita gunakan topologi yang mudah saja seperti dibawah ini

Kemidian kita Setting ip dhcp pada router nya dengan command seperti berikut

Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#int fa0/0
Router(config-if)#ip add
Router(config-if)#ip address 192.168.100.1 255.255.255.0
Router(config-if)#no shut

Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#exit
Router(config)#do wr
Building configuration...
[OK]
Router(config)#ip dhcp pool davidsmk
Router(dhcp-config)#network 192.168.100.0 255.255.255.0
Router(dhcp-config)#def
Router(dhcp-config)#default-router 192.168.100.1
Router(dhcp-config)#dn
Router(dhcp-config)#dns-server 8.8.8.8
Router(dhcp-config)#exit
Router(config)#do wr
Building configuration...
[OK]
Router(config)#

Kemudian kita cek pada pc dengan cara msuk di pc-desktop-ip configuration-dhcp

Kemudian kita setting keamanan dasarnya dulu seperti berikut, baru kita setting ssh nya dengan comment berikut

Router>en

Router#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#username david password 12345

Router(config)#line console 0

Router(config-line)#login local

Router(config-line)#exit

Router(config)#line vty 0 15

Router(config-line)#password 12345

Router(config-line)#login

Router(config-line)#exit

Router(config)#enable secr

Router(config)#enable secret 12345

Router(config)#service pass

Router(config)#service password-encryption 

Kemudian kita set ssh nya dimulai dari command berikut :

Router(config)#hostname david

david(config)#ip domain-name david.net

david(config)#crypto key generate rsa

The name for the keys will be: david.david.net

Choose the size of the key modulus in the range of 360 to 2048 for your

  General Purpose Keys. Choosing a key modulus greater than 512 may take

  a few minutes.

How many bits in the modulus [512]: 1024

% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]

david(config)#ip ssh version 2

*Mar 1 0:11:49.178:  %SSH-5-ENABLED: SSH 1.99 has been enabled 

david(config)#line vty 0 15

david(config-line)#transport input ssh

david(config-line)#password 12345

david(config-line)#login

david(config-line)#exit

david(config)#do wr

Building configuration...

[OK]

david(config)#

jangan lupa menuliskan write agar command kalian tidak terhapus ketika kita startup

Kemudian kita cek dengan cara masuk PC seperti berikut
