Creating a User Account, Setup telnet & Banner

Now we will create a user, before doing that we need to enter the command shown below.  This command will encrypt the password of the user being created, if not it will be shown in clear text

router1(config)# service password-encryption

Now I will create a username called bala

router1(config)# username bala password @ust!nlol

Now I will set the privilege level of bala

router1(config)# username bala privilege 1

Now we will strengthen the enable password to use MD5sum type 5 in other words.

router1(config)# enable secret T3stP@ssw06d

Now we will tell the router to always use type5 password by

router1(config)# no enable password

Now we will control from where Bala can connect from, I am going to use telnet for test purpose

router1(config)# access-list 1 permit 192.168.1.15

router1(config)# access-list 1 deny any

router1(config)# line vty 0 4

Now we are applying the STD access list to our Virtual Telnet lines.

router1(config-line)# access-class 1 in

Now we will also set the exec-timeout, so it will auto timeout if left unattended.

router1(config-line)# exec-timeout 5 0

Now we will apply this to telnet

router1(config-line)# transport input telnet

Now we will make it use of the local database of usename and password

router1(config-line)# login local

Now let us execute the same

router1(config-line)# exec

Now we will create a banner from Privilege exec level.

router1(config)# banner login #For authorized users only !!!#
