System administrator access
The VCS has a default administrator account
with full read/write access. This account is
used to log into the VCS using the web interface
or the CLI. You can add additional administrator
accounts with either read/write access or read-
only access which can be used to log in using
the web interface only. See the
Administrator
accounts
section for information on how to
create these additional accounts.
It is possible to have more than one
!
administrator session running at the
same time. These sessions could be
using the web interface, command line
interface, or a mixture of both. This may cause
issues if each administrator session is
attempting to make the same configuration
changes.
Default administrator account
The default administrator account has a
username of
admin
(all lower case) and a
default password of
TANDBERG
(all upper case).
You cannot delete the default administrator
account or change the
admin
username, but
for security reasons you should change the
password as soon as possible. Choose a strong
password, particularly if administration over IP
is enabled. You will receive a warning on the
web interface and the CLI if the
admin
account
has the default password configured.

account:

You cannot set a blank password for the

user or any other administrator
account, or the
root
account.
Root account
The VCS provides a root account which can be
used to log in to the VCS operating system. This
account has a username of
root
(all lower case)
and a default password of
TANDBERG
(all upper
case). For security reasons you must change
the password as soon as possible. You will
receive a warning on the web interface and the
CLI if the root account has the default password
configured.
The
root
account should not be used in
!
normal operation, and in particular
system configuration should not be
conducted using this account. Use the
admin
account instead.

fields,
By default, the root account can be accessed
over a serial connection or SSH only - access
d
over Telnet is disabled by default. You may wish
to enable access over Telnet, but for security
reasons we do not recommend this.

•
rootaccess -t off

using SSH.
exit
3.
Type

If you have disabled SSH access while
logged in using SSH, your current
session will remain active until you log
out, but all future SSH access will be denied.
If your VCS is part of a cluster, do not

disable root access using SSH. The
clustering feature depends on SSH
access.

Resetting a forgotten administrator or
root password
If you forget the password for the default
account or any other administrator account,
log in to the VCS using the account of another
administrator with read/write access and
change the password.
However, if you do not have any other
administrator accounts with read/write access,
or have forgotten the passwords for them all, it
is possible to set a new password for the
account using the following procedure. This can
also be used if you have forgotten the password
for the
root
account:
1.
Connect a PC to the VCS using the serial
cable as per the instructions in steps 1 and 2
of

2.
Reboot the VCS.

minute following a restart. Beyond that
time you will have to restart the system
again to change the password.
