Username Passwords

WEBGUI

FMADIO Packet Capture Systems use the default login and password when the system is shipped. Additional WebGUI users can be added manually using the htpasswd utility. To set a new password "password" for the fmadio account use the following command line:

fmadio@fmadio20v2-149:$ sudo htpasswd /opt/fmadio/etc/htpasswd fmadio password

By default this utility overwrites the existing user account, so only 1 user account is possible.

WEBGUI Multiple Accounts

Additional users are added by appending to the /opt/fmadio/etc/htpasswd file. The following shows creating a user account "test" with the password "newpassword".

fmadio@fmadio20v2-149:$ sudo htpasswd /tmp/ptmp test newpassword 
fmadio@fmadio20v2-149:$ cat /tmp/ptmp >> /opt/fmadio/etc/htpasswd

Please be careful duplicate usernames are not in the /opt/fmadio/etc/htpasswd file. Use a text editor to adjust the file if needed.

The new users and passwords can now access the GUI. In addition for logging the nginx access logs will show the username for all URL requests.

SSH

Unfortunately adding additional SSH usernames is not possible, as the permissions may be incorrectly set causing undefined system behavior. However multiple people can login to the system using different SSH keys via the .authorized_keys config file.

The authorized ssh keys file is located in

/opt/fmadio/etc/fmadio_authorized_keys

Please note, the authorized_keys file in the users .ssh account directory does not persist across reboots. Keys must be added to the above location.

Change default SSH password

Changing the default SSH password uses the standard linux utilit "passwd".

sudo passwd fmadio

Example below

fmadio@fmadio20v3-287:/etc$ sudo passwd fmadio
Changing password for fmadio
Enter the new password (minimum of 5, maximum of 8 characters)
Please use a combination of upper and lower case letters and numbers.
New password:
Re-enter new password:
passwd: password changed.
fmadio@fmadio20v3-287:/etc$

After setting the new password, it needs to be copied to persistent storage

sudo cp /etc/shadow /opt/fmadio/etc/
