Gns3 lab: Configure HTTP/HTTPS Server On Cisco Router

CONFIGURE HTTP/HTTPS SERVER ON CISCO ROUTER

DESCRIPTION

In this tutorial, we are going to learn many concepts of networking and security.
Networking

[+] We create a design of the network.
[+] We configure the network which consist of:
Configure hostname, domain name.
Generate crypto keys
Configure line vty, interfaces, DHCP Pool.
Create the user.
Configure the HTTP and HTTPS on cisco router.
[+] We verify the accounts by accessing through telnet and SSH.
[+] Access cisco router through browser. (Last activity).

Security
[+] In security, we perform network mapping using nmap tool.
[+] Check how many ports are open after configuring the services on cisco router.
[+] Check version of services running on port 80,443.

NETWORK SCENARIO

[+] Again in this tutorial, we take a very simple network scenario which consists of one cisco router 7200 series and one virtual machine ( running kali linux).

• Network: 10.0.0.0
• Router IP: 10.0.0.1
• Linux IP: 10.0.0.2

[+] See the below image for more details about the network.

CONFIGURE HTTP AND HTTPS SERVER 

CONFIGURE HOSTNAME 

R1(config)#hostname router1

CONFIGURE DOMAIN NAME 

router1(config)#ip domain-name hackingdna.com

GENERATE CRYPTO KEYS 

router1(config)#crypto key generate rsa general-keys modulus 1024

CONFIGURE LINE VTY 

router1#config t

router1(config)#line vty 0 4

router1(config-line)#login local

router1(config-line)#end

router1#

CONFIGURE INTERFACE 

router1#config t

router1(config)#int f0/0

router1(config-if)#ip add 10.0.0.1 255.0.0.0

router1(config-if)#no shut

router1(config-if)#exit

router1(config)#

CONFIGURE DHCP POOL 

router1(config)#ip dhcp pool networkingdna

router1(dhcp-config)#network 10.0.0.0

router1(dhcp-config)#dns-server 10.0.0.1

router1(dhcp-config)#default-router 10.0.0.1

router1(dhcp-config)#exit

router1(config)#end

router1#

CONFIGURE HTTP SERVER 

router1(config)#ip http server

router1(config)#ip http secure-server

router1(config)#ip http authentication local

CREATE USER 

router1(config)#username vivek privilege 15 password 0 12345

router1(config)#logging buffered 51200 warning

router1(config)#

VERIFYING SSH

ACCESS TELNET 

PERFORMING ENUMERATION OF HTTP AND HTTPS

VERSION SCAN 

• Find out what information you will get when you perform a version scan on port 80 and 443
• See the below output of nmap:

SSLSCAN

• Now we know that ssl is running on port 443. Lets confirm it which version of ssl is running on this cisco router.
• We can make this work easier by using sslscan. You can find this tool easily on kali linux or simply you can download from the repositories. 
• Lets see the output of sslscan.

ACCESSING ROUTER PAGE THROUGH HTTPS 

• To access this page, open your web browser and enter the router ip address.
• As you enter the router ip, it shows some exception. Click on add exception to move forward.
• See the below image for more help-

 ENTER THE USERNAME PASSWORD 

• To access the router, we need to enter the (username) and password (12345).
• See the below image for more details:

FINALLY YOU REACHED YOUR DESTINATION

AT THE END

• If you configure and practice this way you can make your networking and security more interesting.
