Telnet gibi güvenlik açığı olan bir protokol kullanmak yerine giriş bilgilerinizi ve verileri akışlarınızı şifreleyecek daha güvenli olan bir protokol olanSecure Shell (SSH) kullanabilirsiniz. Bu sizi ve verilerinizi daha güvende hisetmenizi sağlayacaktır.
Şimdi adım adım SSH nasıl kurulacağını göreceğiz:
1. Hostname settings are made:
Router(config)#hostname techsoftcenter |
2. The area call is about (right here hostname and area call are required to generate encrypted keys):
Todd(config)#ip domain-name techsoftcenter.com |
3. Encrypted keys are generated to soundly behavior the consultation:
Todd(config)#crypto key generate rsa general-keys modulus ? <360–2048>measurement of the key modulus[360–2048] Todd(config)#crypto key generate rsa general-keys modulus 1024 The call forthe keys will be:techsoftcenter.com %Thekeymodulusmeasurementis1024bits %Producing1024bitRSAkeys,keyswillbenon–exportable…[OK] *April2311:30:30.035:%SSH–5–ENABLED:SSH1.99has been enabledCisco Internetworking Working Gadget(IOS)ve Safety Tool Supervisor(SDM) |
4. We create a username and password.
techsoftcenter(config)#username fadil password f123. |
5. The utmost idle (idle) timer is about for SSH consultation: (assigns person after 60 seconds)
techsoftcenter(config)#ip ssh time-out ? <1–120>SSH time–out period(secs) techsoftcenter(config)#ip ssh time-out 60 |
6. The utmost collection of unsuitable entries is about for an SSH connection:
techsoftcenter(config)#ip ssh authentication-retries ? <0–5>Quantity of authentication retries techsoftcenter(config)#ip ssh authentication-retries 2 |
7. We will be able to decide the SSH model.
techsoftcenter(config)#ip ssh model 2 |
8. A connection to the vty strains of the router is established:
techsoftcenter(config)#line vty 0 1180 techsoftcenter(config–line)#login native (asks for the person’s call and password in native) |
The closing step is to configure SSH and Telnet as get entry to protocols:
techsoftcenter(config–line)#shipping enter ssh telnet |
Should you don’t use telnet on the finish of the command line, simplest SSH will paintings at the router. It’s not beneficial to make use of each in combination, as a result of it is vital to understand that SSH is more secure than Telnet.
I’m hoping it used to be an invaluable article.
