System Administrator Access

About Administrator Access

While it is possible to administer the TANDBERG VCS via a PC connected directly to the unit via a serial cable, you may wish to access the system remotely over IP.
You can do this using either or both:
the web interface via HT TPS
•
a command line inter face via SSH or Telnet.
•
By default, access via HT TPS and SSH is enabled; access via Telnet is disabled.
You can also enable access via HTTP. However, this mode works by redirecting HTTP calls to the HTTPS por t, so HT TPS must also be enabled for access via HTTP to function.
TMS accesses the VCS via the web server. If HTTPS mode is turned off, TMS will not be able to access it.

Configuring Administrator Access

To configure the ways in which your system is accessed:
System Configuration > System.
•
You will be taken to the System Administration page. In the Admin Access section, select Off or On from the drop ­down boxes for each service.
xConfiguration Administration
•
You must restart the system for changes to take effect.

Administrator Account Password

All administration requires you to log in to the administration account with the username admin (all lower case) and a password.
Both the username and password are case- sensitive.
Default Administrator Password
The default password is TANDBERG (all upper case). You should change this as soon as possible. Choose a strong password, particularly if administration over IP is enabled.
Changing the Administrator Password
To change the administrator password:
Maintenance > Passwords.
•
You will be taken to the Passwords page. In the Administrator Password section, enter and then retype the new password.
xConfiguration SystemUnit Password
•
To set an empty password t ype:
xConfiguration SystemUnit Password: “”
Resetting the Administrator Password
If you forget your password, it is possible to set a new password using the following procedure:
Reboot the VCS.
1.
Connect to the VCS using the serial cable.
2.
Login with the username pwrec. No password is required.
3.
You will be prompted for a new password.

Session Timeout

By default, Administrator sessions do not time out – they remain active until you logout.
However, you can set the system to timeout an Administrator session after a set number of minutes of inactivity. The timeout period will apply to Administrator sessions using both the Web Interface and the Command Line Interface.
To set the timeout period:
System Configuration > System.
•
You will be taken to the System Administration page. In the Admin Access section, in the Session time out
(minutes) box, enter the number of minutes of inactivit y after
which an administrator session should time out.
xConfiguration Administration TimeOut
•
Values must be between 0 and 10,000. A value of 0 means that Administrator sessions will never time out.
You must restart the system for changes to take effect.

Root Account

The VCS provides a root account with the same password as the Admin account. This 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.

Security Considerations

To securely manage the VCS you should disable Telnet, using the encrypted HTTPS and SSH protocols instead.
For fur ther security, disable HTTPS and SSH as well and use the serial port to manage the system.

Configuration
The pwrec account is only active for one minute following a restar t. Beyond that time you will have to restar t the system again to change the password.
Because access to the serial port allows the password to be reset, it is recommended that you install the VCS in a physically secure environment.

Configuring System Settings

To configure the VCS’s system administration settings:
System Configuration > System.
•
You will be taken to the System
Administration page.
xConfiguration SystemUnit Name
•
xConfiguration Administration
•

About the System Name

The system name is used to identify the VCS, for example in TMS.
It appears in various places in the web interface, and in the display on the front panel of the unit, so that you can identify it when it is in a rack with other boxes. If no name is specif ied, these fields/display will be blank.
We recommend that you give the VCS a name that allows you to easily and uniquely identify it.

About Admin Access settings

While it is possible to administer the TANDBERG VCS via a PC connected directly to the unit via a serial cable, you may wish to access the system remotely over IP.
You can do this using either or both:
the web interface via HT TPS
•
a command line inter face via SSH or
•
Telnet.
By default, access via HT TPS and SSH is enabled; access via Telnet is disabled.
You can also enable access via HTTP. However, this mode works by redirecting HT TP calls to the HTTPS port, so HTTPS must also be enabled for access via HTTP to function.
Save
Click here to save your changes.
You must save your changes and restar t the system for changes to take effect.
Restar t
Click here to restart the system.
TMS accesses the VCS via the web server. If HTTPS mode is turned off, TMS will not be able to access it.
System name
Defines the name of the VCS. Choose a name that uniquely identifies the system.
Session time out (minutes)
Sets the number of minutes that an administration session (HTTPS, Telnet or SSH) may be inactive before the session is timed out. A value of 0 turns session time outs of f.
Telnet service
Determines whether the VCS can be accessed via Telnet.
SSH service
Determines whether the VCS can be accessed via SSH and SCP.
HTTP service
Determines whether HTTP calls will be redirected to the HTTPS port.
HTTPS service
Determines whether the VCS can be accessed via the web server. This must be On to enable both web interface and TMS access.
By default, access via HT TPS and SSH is enabled; access via Telnet is
disabled. To securely manage the VCS you should disable Telnet, using the encrypted HTTPS and SSH protocols instead. For further security, disable HTTPS and SSH as well and use the serial por t to manage the system.

Configuring IP Settings

To configure the VCS’s IP settings:
System Configuration > IP.
•
You will be taken to the IP page.
xConfiguration IP
•
xConfiguration IPProtocol
•
The VCS is shipped with a default IP address of 192.168.0.100. This
allows you to connect the VCS to your network and access it via the default address so that you can configure it remotely.

About IPv4 to IPv6 Gatewaying

The VCS can act as a gateway between IPv4 and IPv6 calls.
To configure the VCS to act as a gateway between the two protocols, select an IP Protocol of Both.
Calls for which the VCS is acting as an
IPv4 to IPv6 gateway count as traversal
calls for the purposes of licensing.
Some endpoints suppor t both IPv4 and
IPv6, however an endpoint can use
only one protocol when registering with the VCS. Which protocol it uses will be determined by the format used to specify the IP address of the VCS on the endpoint. Once the endpoint has registered using one protocol, calls to it from an endpoint using the other protocol will be gatewayed by the VCS.

IPv6 gateway
Specifies the IPv6 gateway of the system.
IP protocol
You can configure the VCS to use IPv4, IPv6 or
Both protocols. The default is Both.
IPv4: The VCS will only accept registrations
from endpoints using an IPv4 address, and will only take calls between two endpoints communicating via IPv4. It will communicate with other systems via IPv4 only.
IPv6: The VCS will only accept registrations
from endpoints using an IPv6 address, and will only take calls between two endpoints communicating via IPv6. It will communicate with other systems via IPv6 only.
Both: The VCS will accept registrations
from endpoints using either an IPv4 or IPv6 address, and will take calls using either protocol. If a call is between an IPv4 -only and an IPv6- only endpoint, the VCS will act as an IPv4 to IPv6 gateway. It can communicate with other systems via either protocol.
IPv4 address
Specifies the IPv4 address of the system.
IPv4 subnet mask
Specifies the IPv4 subnet mask of the system.
IPv4 gateway
Specifies the IPv4 gateway of the system.
IPv6 address
Specifies the IPv6 address of the system.

Configuring DNS Settings

To configure the VCS’s DNS settings:
System Configuration > DNS.
•
You will be taken to the DNS page.
xConfiguration IP DNS
•

About DNS Servers

In order to use URI dialing or ENUM dialing, you must specify a DNS ser ver to be queried for address resolution. You can specify up to 5 DNS ser vers. Normally only the f irst DNS server will be queried, but if it fails to respond, all DNS ser vers will be queried.

About the DNS Domain Name

The DNS Domain Name is used when attempting to resolve ser ver addresses configured on the VCS that are not fully qualified. It applies only to the following:
LDAP ser ver
•
NTP ser ver
•
External Manager ser ver.
•
The DNS Domain Name is appended to the server address before a query to the DNS server is executed. Note however that DNS will also be queried for the ser ver address as configured, without the DNS Domain Name appended. For this reason we recommend that all server addresses use a FQDN.
The DNS Domain name plays no part in URI dialing.
Address 1 to Address 5
Sets the IP address of a DNS server to be queried when resolving domain names.
Domain name
Specifies the name to be appended to the host name before a query to the DNS server is executed.

About the NTP Server

Accurate timestamps play an impor tant part in authentication, helping to guard against replay attacks. For this reason, we recommend that you use an NTP server to synchronize the system time.

Setting the Time Zone

All events are recorded using the local date and time as well as UTC time. The local time is determined by the Time Zone set on the VCS.
NTP ser ver
Sets the IP address or FQDN of the NTP server to be used when synchronizing system time.
Time zone

About SNMP Settings

The VCS of fers basic support for SNMP.
Tools such as TANDBERG Management Suite (TMS) or HP OpenView may act as SNMP network management systems (NMS). They allow you to monitor your network devices, including the VCS, for conditions that might require administrative attention.
To allow the VCS to be monitored by a SNMP NMS, you must enable SNMP on the VCS and provide the name of the SNMP community within which it resides. You may optionally provide the name of a System contact and the physical Location of the system for reference by administrators when following up on queries.
By default, SNMP is Enabled with a SNMP
community name of public.
Note: the VCS does not support SNMP traps, therefore it cannot be managed via SNMP.
Enabled
Select On to enable SNMP suppor t.
You must save your changes and restar t the system for any changes to take effect.

Logging Overview

TANDBERG VIDEO COMMUNICATION SERVER
TANDBERG VIDEO COMMUNICATION SERVER
ADMINISTRATOR GUIDE
ADMINISTRATOR GUIDE

About Logging

The VCS provides a logging facility for troubleshooting and auditing purposes. The event log contains information about such things as calls, registrations, and messages sent and received.
The VCS logging facilit y allows you to:
specif y the amount of information that is
•
logged by changing the event log level,
specif y an external server to which a copy
•
of the log is written.

About Remote Logging

The event log is stored locally on the VCS. However, it is often convenient to collect copies of all event logs from various systems in a single location. A computer running a BSD-style syslog server, as defined in RFC 3164 [4] , may be used as the central log server.
A VCS will not act as a central logging
server for other systems.

Enabling Remote Logging

To enable remote logging, you must configure the VCS with the address of the central log server. To do this:
System Configuration > Log ging.
•
You will be taken to the Logging page.
xConfiguration Log Ser ver
•
Address

About Event Log Levels

All events have an associated level in the range 1-3, with level 1 events considered the most impor tant. The table below gives an over view of the levels assigned to different events.
See Events Logged at Level 1, Events Logged at Level 2 and Events Logged at Level 3 for complete tables of the events logged at each level.
Level Assigned Events
Level 1 (User)
Level 2 (Protocol)
Level 3 (Protocol Verbose)
High-level events such as registration requests and call at tempts. Easily human readable. For example:
call attempt/connected/disconnected
•
registration at tempt/accepted/rejected.
•
Logs of protocol messages sent and received (H.323, LDAP, etc.) excluding noisy messages such as H.460.18 keepalives and H.245 video fast­updates.
Protocol keepalives are suppressed at Level 2. At log ging Level 3, keepalives are also logged.

Setting the Event Log Level

You can control which events are logged by the VCS by setting the log level. All events with a level numerically equal to and lower than the specified log ging level are recorded in the event log.
To set the log level:
System Configuration > Log ging.
•
You will be taken to the Logging page.
xConfiguration Log Level
•
Remote syslog server
Enter the IP address or FQDN of the ser ver to which the log will be written.
Log level
Select the level of logging you require.
The default is 1.
Events will be always logged locally
regardless of whether or not remote
logging has been enabled.
