Introduction to Cisco IOS CLI (Command-Line Interface)

Hello Laz,
1.Connection throught console using Putty
no logging console is one of the first cli commands that I learned !

2.Before saving, show running-config and show startup-config display exactly the same
Normally since Ram is different from Nvram, it should display different results.
Anyway, afer Router1#copy running-config startup-config and or Router1#write
Naturally nothing’s changed.

3.As you said I changed hostname router to Router1 with no logging console and ip address

Router1#write
Building configuration...
[OK]
Router1#show run
Building configuration...
Current configuration : 589 bytes
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
hostname Router1
boot-start-marker
boot-end-marker
no logging console
no aaa new-model
resource policy
ip cef
interface FastEthernet0/0
no ip address
shutdown
duplex auto
speed auto
interface FastEthernet0/1
 ip address 192.168.1.253 255.255.255.0
 duplex auto
 speed auto
no ip http server
no ip http secure-server
control-plane
line con 0
line aux 0
line vty 0 4
 login
scheduler allocate 20000 1000
end

Now for control this is the startup-config

Router1#show startup-config
Using 589 out of 196600 bytes
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
hostname Router1
boot-start-marker
boot-end-marker
no logging console
no aaa new-model
resource policy
ip cef
interface FastEthernet0/0
 no ip address
 shutdown
 duplex auto
 speed auto
interface FastEthernet0/1
 ip address 192.168.1.253 255.255.255.0
 duplex auto
 speed auto
no ip http server
no ip http secure-server
control-plane
line con 0
line aux 0
line vty 0 4
login
scheduler allocate 20000 1000
end

4.Power off and on and it comes back with the message
Would you like to enter the initial configuration dialog? [yes/no]
with prompt router>

What do you suggest ?
