Out-of-band management credentials

This page describes how to manage the credentials for the out-of-band management interfaces used in the Digital Signal PSI servers and devices.

The current credentials for all systems can be found in Vault at digital-signal-psi/credentials.

Rotating a password is very straight-forward:

Change the password on the management interface using one of the guides below
Update the entry in Vault with the new password

Device-specific Instructions

Edge-Core DCS810 P4 switch

The Edge-Core DCS810 P4 switch runs a version of OpenBMC on the management interface. The file system on the BMC is volatile, so any changes made to the BMC OS is not persisted between reboots, with the exception of data in /mnt/data. Customization of the BMC environment is therefore managed through /mnt/data/etc/rc.local, which is executed when the BMC boots up.

This script is also used to change the password of the root user. To change it, SSH into the BMC with the current credentials, and edit the script with:

vi /mnt/data/etc/rc.local

It should contain a section like the following:

/mnt/data/etc/rc.local

# change root password
passwd << EOF
<password>
<password>
EOF

Change both lines containing the current password with the new password and save the file. Then, reboot the switch and check whether the password was changed successfully.

Dell EMC OS10 switch

The Dell OS10 switch has two administrator users:

The linuxadmin user is part of the underlying linux OS, and acts as the system’s root user
The admin user is part of OS10, and is the default user with the sysadmin role

How to change the `linuxadmin` user password

To change the password of the linuxadmin system user, connect to the OS10 CLI and use the following commands:

ds-psi-sw-02# configure terminal
ds-psi-sw-02(config)# system-user linuxadmin password <new_password>
ds-psi-sw-02(config)# exit
ds-psi-sw-02# write memory

For more information, refer to Linuxadmin user configuration.

How to change the `admin` user password

To change the password of the admin user, connect to the OS10 CLI and use the following commands:

ds-psi-sw-02# configure terminal
ds-psi-sw-02(config)# username admin password <new_password> role sysadmin
ds-psi-sw-02(config)# exit
ds-psi-sw-02# write memory

For more information, refer to user password role.

Raritan Rack PDU

To change the admin password using SSH:

$ ssh admin@192.168.71.5
admin@192.168.71.5's password:
