I am trying to backup my configuration on a Juniper m120 OS version 10.1R1.8. I would prefer not to use the archival server configuration because a custom application will kick off backup and not the router itself. My user's login class is 'super-user' and therefore should have all permission bits set including 'secret' unless I have misunderstood something. I have tried: show configuration and edit #save my-config In either case, the root and user account passwords are encrypted in the output.
What should I do? I appreciate your help! The string shown in the password field of user and root accounts in the Junos configuration is not the password encrypted, but a salted MD5 hash of the password. A hash by nature is a one-way function - in other words, there is no functional way to take a hash and convert it back to the original password. When you log into the box, the password you enter is run through the same hashing algorithm (with the salt for that user account applied) and the results are compared - if they match, then Junos knows that the password you entered must be the same as the one that generated the hash that is stored in the configuration.
Regarding the secret permission bit in Junos: this allows you to view sections of the configuration that contain these hashes - if you do not have the secret permission bit set, you will not see any of them - it does not show the original passwords. I'm not sure why you need to see the password in plaintext format even if you are backing up configuration? If you restore a backed up configuration to the box, the hash will remain the same and your password will continue to work.
Crack Encrypted Password
Some time ago during a configuration review of a Juniper JUNOS device I noticed some sort of hash format starting with $9$. Wondering what format was being used I searched on Google and found a that was able to get the password instantly. This means that the password is stored in a reversable format and is not a real hash, but some sort of obfuscation. This is similar to the Cisco type 7 password obfuscation, which use the. While you can find many tools to decrypt Cisco type 7 password there are no offline tools you could use for Juniper $9$. After some more searches I found a convenient Perl library named, which allows you to decrypt $9$ passwords. While I am not an experienced Perl coder I wrote th following proof of concept within 5 minutes.
Hi Ricky, Junos actually does this by default - all passwords are stored in either encrypted or hashed format depending on their usage. You have to remember that some of these protocols use symmetric encryption and the router actually NEEDS to be able to decrypt the key in the config in order to operate the protocol. User authentication uses completely asymmetric encryption - eg: we don't care what the password is as long as the hash matches, so these can be one-way $1$ encrypted - the local box has a salt which it feeds into it's encryption algorithm of choice to generate and compare the hash of the user's password, thus never having to actually store it. Protocols like OSPF however need to transmit information across the network, which means both ends need a common way of decrypting the information, and one that isn't particularly processor intensive - thus the need for reversible/symmetric encryption (and storing keys in a reversible format).
I hope this makes sense!
Configuring the root password on your Junos OS-enabled router helps prevent unauthorized users from making changes to your network. The root user (also referred to as superuser) has unrestricted access and full permissions within the system, so it is crucial to protect these functions by setting a strong password when setting up a new router. After a new router is initially powered on, you log in as the user root with no password. Junos OS requires configuration of the root password before it accepts a commit operation. On a new device, the root password must always be a part of the configuration submitted with your initial commit. To set the root password, you have a few options as shown in Step 1 of the following procedure.
Enter a plain-text password that Junos OS encrypts. Enter a password that is already encrypted. Enter a secure shell (ssh) public key string. The most secure options of these three are using an already encrypted password or an ssh public key string. Pre-encrypting your password or using a ssh public key string means the plain-text version of your password will never be transferred over the internet, protecting it from being intercepted by a man-in-the-middle attack. Best Practice Optionally, instead of configuring the root password at the edit system hierarchy level, you can use a configuration group to strengthen security, as shown in Step 2 of this procedure.
This step uses a group called global as an example. To set the root password:. Use one of these methods to configure the root password:. To enter a plain-text password that the system encrypts for you. Retype new password: retype password here If you use a plain-text password, Junos OS displays the password as an encrypted string so that users viewing the configuration cannot see it. As you enter the password in plain text, Junos OS encrypts it immediately. You do not have to configure Junos OS to encrypt the password as in some other systems.
Plain-text passwords are hidden and marked as ## SECRET-DATA in the configuration. To enter a password that is already encrypted: Caution Do not use the encrypted-password option unless the password is already encrypted, and you are entering the encrypted version of the password. If you accidentally configure the encrypted-password option with a plain-text password or with blank quotation marks (' '), you will not be able to log in to the device as root, and you will need to complete the root password recovery process.
