    I am wanting to go from version 4.1.1.0 of BRE to 4.1.4 however I have saved my password in the BRE and no longer remember it - or better it's not what I thought it was :p

    The only password changer that I know of is the 'changeBrainPassword.py' script in the bin/ dir however this requires knowing the old password.

    Aside from removing my old account and creating a new account - which would require a server restart - is there any other way of resetting a user's password? Is there anyway of migrating the stored password into the newer version? Can I blank my existing password in the passwd file to reset it? I've noticed a 'getPasswordHash.py' in conf/brain/ can I perhaps use this to hash my pass and replace the old pass in the passwd file?

    Ideally the solution wouldn't involve restarting the server since we are a multi-user environment.


    Thanks in advance,
    Burke

    Good Day,

    Up to the 4.1.4 release there is not a way to modify the password file without restarting the server. However; for your own information going forward, the 4.1.4 release of BRAIN comes with the enhancement that you may now modify users and user-passwords without restarting the server. It only requires toggling your BRE connection with the server.

    I can change my password and / or create a new user and still connect by simply disconnecting the client and reconnecting?

    So theoretically if I hand edit/change the hash in passwd by using the 'getPasswordHash.py' script to hash a new pass for the passwd I should be able to connect?

    If you in fact are currently running a 4.1.4 server then I do believe that the modifications you are speaking of will be picked up, and useable when you reconnect to the server with BRE.

    Upon rereading your post, I had originally thought you were upgrading the entire setup, not just BRE, and thus were on an older server.

    Well I gave it a try and sure enough it worked.

    used the following:
    python /opt/lavastorm/brain4.1.4/conf/brain/getPasswordHash.py burke
    which returned:
    hash(burke)=25263B46ABC397CCC27574EC1D242300
    Then replaced the old hash in the passwd with the new hash and connected successfully without restarting the server.

    Thanks for your help.

    p.s For the record I used a password a BIT more secure than the example given above

    I am finding that although I can connect and execute graphs, it appears I am failing authentication when trying to view node output.

>>     method:brain-auth

    When I connect with a generic account we had previously setup I can view the node output.

    So it appears in order to read the node outputs a server restart will be required.

    If you have not, please try a restart of BRE. This is to check if BRE has the old password cached somewhere. If you can execute graphs, you should be able to check the outputs.
    I will attempt to reproduce this in house today.
