This is an office migration, and my users messed up the server equipments. Now, I have to access the firewall set through the console, as web admin is not possible due to IP restriction set by one of the user with documentation.

My intention is to access to the set, and then get to know what/which ports were being configured as External and internal. What commands should I type to get know the IPs assigned to the ports?

BTW, I also intend to reset the password  without affecting the configuration. Can I do it?

get int

from the console will tell you what each interface has assigned as ip address

set admin password "password"

will allow you to change the admin: this will not mess up the config

Hi Sangamc,

BTW, what is the console port settings? 9600? 19200? 38400? or 57600?

How can I reset the password?

my console settings are
bps: 9600
data bits: 8
parity: none
stop bits: 1
flow control: none

# set admin password "your new password"

this will change the password of the root account on the device

Hi Sangamc,

The problem is now I can't access to the device, how can I reset the admin's password?

Is there a way to reset password to factory settings. Now, I don't mind losing all the config.
I saw there is a reset pin on the front panel. Whether this pin is meant for this action?

i see your problem now, to do a hardware reset you use the pin hole on the front i believe you need to follow these steps.

http://www.juniper.net/techpubs/hardware/netscreen-systems/netscreen-systems60/HW_SSG140_600.pdf


Using the device status LEDs:
1. Locate the Reset (or Reset Config) pinhole on the device. Using a thin wire
(such as a straightened paperclip), push the pinhole button for four to six
seconds.
The Status LED blinks red.
2. As soon as the Status LED blinks green, release the pinhole button and wait
two seconds.
3. The device now waits for the second reset, which confirms the operation.
Push the pinhole button again for four to six seconds until the device resets.
The system now resets and returns to the login prompt; the default login name
and password are both reset to netscreen.


Using the Console:
1. Start a Console session as described in Using a Console Connection on
page 22.
2. Locate the Reset pinhole on the device. Using a thin wire (such as a
straightened paperclip), push the pinhole button for four to six seconds.
The message Configuration Erasure Process has been initiated appears in
the console window. Continue to press the pinhole button until the
message Waiting for 2nd confirmation appears.
NOTE:
If you do not follow the complete sequence, the reset process cancels without any
configuration change and the console message states that the erasure of the
configuration is aborted. The Status LED returns to blinking green. The device
generates SNMP and SYSLOG alerts to configured SNMP or SYSLOG trap hosts.

3. Release the pinhole button, and wait two seconds.
4. Push the pinhole button again for four to six seconds.
The message 2nd push has been confirmed appears.
5. Continue to press the pinhole button until the device resets.
The system now resets and returns to the login prompt; the default login name
and password are both reset to netscreen

hello Balack
sorry but i was searching how to reset the password without resetting the configs
& i didnt find any
but i've found that if you can connect to through the serial port
go to your device & locate the serial number
type your serial number in both user name & password
this will rest it to the factory settings in a second

thanks
