Interfaces
The PT22 has two interfaces: the HTML interface accessed via the HTTP enabled Ethernet connections
and the command line for serial and Telnet connections.
Outlet Naming and Grouping
For commands requiring an outlet name, you may specify it in one of two ways: a predefined absolute
name or a descriptive name assigned by an administrator.
For units with multiple infeed connectors, absolute names are specified by a period (.) followed by the
tower letter, the infeed letter and outlet number.
Example: The absolute name for outlet 8 on the B infeed of tower A is .AB8.
Outlets may also be included in one or more named groups of outlets, enabling you to issue a command
that affects all outlets in a named group.
Usernames and Passwords
The PT22 has one predefined administrative user account (username/password: admn/admn) and supports
a maximum of 128 defined user accounts
NOTE: For security, Server Technology recommends removal of the predefined administrative user account after a new
account with administrative rights has been created.
Only an administrative-level user may perform operations such as creating/removing user accounts and
command privileges, changing passwords and displaying user information. An administrator may also
view the status of all sensors and power inputs.
Usernames may contain from 1-16 characters and are not case sensitive; spaces are not allowed.
Passwords may contain up to 16 characters, and are case sensitive.

Changing the HTTP server port number:
In the HTTP Port field, enter the port number and press Apply.
Setting the HTTP authentication method:
The Sentry HTTP server supports two authentication methods for security and validation of the
username-password – Basic and MD5 digest.
The Basic method utilizes Base64 encoding to encode and deliver the username-password over the
network to the HTTP server for decoding and authentication. This basic method is supported by all
web browsers and offers a minimum level of security.
NOTE: The Base64 algorithm is widely-known and susceptible to packet-sniffer attack for acquisition of the encoded
username-password string.
The MD5 digest method provides stronger protection utilizing one-way encoded hash numbers, never
placing the username-password on the network. Instead, the sending browser creates a challenge code
based on the hash algorithm, provided username-password and unique items such as the device IP
address and timestamp, which is compared against the HTTP server internal user database of valid
challenge codes. The MD5 digest method offers a higher level of security than the Basic method but at
present is not supported by all browsers.
NOTE: MD5 is known to be fully supported by Internet Explorer 5.0+
Select Basic or MD5 from the Authentication drop-down menu and press Apply.

SSL
Secure Socket Layers (SSL) version 3 enables secure HTML sessions between a Sentry Remote Power
Manager and a remote user. SSL provides two chief features designed to make TCP/IP (Internet)
transmitted data more secure:
•
•
Authentication – The connecting client is assured of the identity of the server.
Encryption – All data transmitted between the client and the server is encrypted rendering any
intercepted data unintelligible to any third party.
SSL uses the public-and-private key encryption system by RSA, which also requires the use of digital
certificates. An SSL Certificate is an electronic file uniquely identifying individuals or websites and
enables encrypted communication; SSL Certificates serve as a kind of digital passport or credential.
The Sentry product’s SSL Certificate enables the client to verify the Sentry’s authenticity and to
communicate with the Sentry securely via an encrypted session, protecting confidential information
from interception and hacking.

SSH
Secure Shell (SSH) version 2 enables secure network terminal sessions between a Sentry Remote
Power Manager and a remote user over insecure network. SSH provides an encrypted terminal sessions
with strong authentication of both the server and client, using public-key cryptography and is typically
used as a replacement for unencrypted Telnet. In addition to enabling secure network terminal sessions
to the Sentry for configuration and power management, the SSH session may be used for secure Pass-
Thru connections to attached devices.
SSH requires the configuration and use of a client agent on the client PC. There are many freeware,
shareware or for-purchase SSH clients available. Two examples are the freeware client PuTTY and the
for-purchase client SecureCRT® by VanDyke® Software. For configuration and use of these clients,

SNMP Traps
The Sentry supports three types of SNMP traps. Traps are enabled at the tower (T), infeed (I) or outlet
(O) level.
Trap Summary

All traps include the Location of the Sentry as defined with the Set Location command.
Status trap
A Status trap is generated when an error condition occurs on a tower, infeeed, Environmental Monitor
or individual sensor. Status traps include the reported Status, the Location of the Sentry and identifier
and name of the affected tower, infeed, outlet, environmental monitor or sensor.
Any error state generates a Status trap and triggers the trap timer. A new trap is generated at the end of
every timer period until the Status returns to a non-error status. All status traps are enabled by default.

NOTE: Traps are generated according to a hierarchical architecture; i.e. if a Tower Status enters a trap condition, only the
Tower Status trap is generated. Infeed and Outlet Status traps are suppressed until the Tower Status returns to Normal.
Change trap
The Change trap is generated for all outlet status changes between any on/off conditions. Change traps
include the outlet status, Location of the Sentry, and identifier and name of the affected outlet. For
descriptions of the outlet status types, please refer to the prior table.

Load Trap
The Load trap is generated whenever the total input load on an infeed exceeds a preset threshold. Load
traps include the reported input load, load status, Location of the Sentry, and identifier and name of the
affected infeed.
Any error state generates a Load trap and triggers the trap timer. A new trap is generated at the end of
every timer period until the Load returns to a non-error status.

LDAP
The Sentry family of products supports Lightweight Directory Access Protocol (LDAP) Version 3. This
support enables authentication with LDAP servers; user accounts do not need to be individually created
locally on each Sentry device.
This allows administrators to pre-define and configure (in each Sentry product, and in the LDAP
server) a set of necessary LDAP Groups, and access rights for each. User’s access rights can then be
assigned or revoked simply by making the user a member of one-or-more pre-defined Sentry LDAP
Groups. User accounts can be added, deleted, or changed in the LDAP server without any changes
needed on individual Sentry products.
Sentry 5.3b LDAP support has been tested in the following environments:
•
•
•
Microsoft Active Directory (MSAD)
Novell eDirectory (eDir)

Enabling and Setting up LDAP Support
There are a few configuration requirements for properly enabling and setting up LDAP support. Below
is an overview of the minimum requirements.
Directory Services server configuration requirements:
1. Define at least one LDAP group.
2. Assign users to that LDAP group.
Sentry configuration requirements:
1. Enable LDAP support.
2. Define the IP address and domain component of at least one Directory Services server.
3. Set the LDAP bind request method being utilized by the Directory Services server.
4. Define the IP address of at least one DNS server.
5. Test DNS server configuration using Sentry ‘ping’ support.
6. Define at least one LDAP group and assign access rights for that group.
NOTE: LDAP group names on the Directory Service server and the Sentry must match.
Enabling and disabling LDAP support
The Set LDAP command is used to enable or disable LDAP support.
To enable or disable LDAP support:
At the Sentry: prompt, type set ldap, followed by enabled or disabled and press Enter.
Setting the LDAP host IP address
The Set LDAP HostIP command sets the TCP/IP address of the Directory Services server.
To set the LDAP host IP address:
At the Sentry: prompt, type set ldap, followed by hostip1 or hostip2 and the Directory Services
server’s IP address. Press Enter.
Example
The following command sets the primary Directory Services server IP address to 98.76.54.32:
Sentry: set ldap hostip1 98.76.54.32<Enter>
Changing the LDAP server port
The Set LDAP port command sets the port to which the Sentry sends LDAP requests to on the
previously defined LDAP server. The default port is 389.
To change the LDAP server port:
At the Sentry: prompt, type set ldap port, followed by the port number and press Enter.
Example
The following command sets the LDAP server port number to 8888:
Sentry: set ldap port 8888<Enter>
Setting the LDAP bind password type
The Set LDAP Bind command sets the password type used in the bind requests. The Sentry supports
two LDAP bind methods – Simple and MD5.
The Simple method utilizes unencrypted delivery of a username-password over the network to the
Active Directory server for authentication.
The MD5 digest method provides much stronger protection utilizing one-way encoded hash numbers,
NOTE: Windows 2000 is known only to support Simple binding. Windows 2003 supports both Simple and MD5 binding.
To set the bind password type:
At the Sentry: prompt, type set ldap bind, followed by simple or md5 and press Enter.

password and press Enter.
Setting the group membership attribute.
The Set LDAP GroupAttr command is used to specify the name of user class attributes that lists
distinguished names (DN), or names of groups that a user is a member of. Maximum string length is 30
characters.
To set Group Membership Attribute:
At the Sentry: promp, type set ldap groupattr and press Enter. At the following prompt, type the
group membership attribute and press Enter.
Example
The following sets the group membership attribute for MSAD to ‘memberof’:
Sentry: set ldap groupattr<Enter>
Enter Group Member Attr (Max character 30):
memberof<Enter>
Setting the group membership value type:
The Set LDAP GroupType command is used to specify whether the values of Group Membership
Attribute represent the Distinguished Name (DN) of a group or just the name of the group.

Setting the user search base Distinguished Name (DN)
The Set LDAP UserBaseDN command is used to set the base (DN) for the login username search. This
is where the search will start, and will include all subtrees. Maximum size is 100 characters.
To set the user search base DN:
At the Sentry: prompt, type set ldap userbasedn and press Enter. At the following prompt, type the
search base DN and press Enter.
Example
The following sets the DN user search base for MSAD to ‘cn=Users,dc=servertech,dc=com’:
Sentry: set ldap userbasedn<Enter>
Enter User Search Base DN (Max characters 100):
cn=Users,dc=servertech,dc=com<Enter>
Setting the user search filter
The Set LDAP UserFilter command is used to set the search filter for the username entered at the login
prompt.
The search filter must be entered within parenthesis and adhere to the following format:
(searchfilter=%s)
where ‘searchfilter’ is the name of the attribute in the user class which has a value that represents the
user’s login name. In this string, the ‘%s’ will be replaced by the entered username. Maximum string
length is 100 characters.
To set the user search filter:
At the Sentry: prompt, type set ldap userfilter and press Enter. At the following prompt, type the
User Search Filter and press Enter.
Example
The following sets the user search filter for MSAD to ‘samaccountname’:
Sentry: set ldap userfilter<Enter>
Enter User Search Filter (Max characters 100):
(samaccountname=%s)<Enter>
Setting the authentication order
The Set Authorder command sets the authentication order for remote authentication sessions. The
Sentry supports two methods for authentication order - Remote -> Local and Remote Only.
The Remote -> Local method first attempts authentication with the Active Directory server and if
unsuccessful with the local user database on the Sentry device.
The Remote Only method attempts authentication only with the Active Directory server and if
unsuccessful, access is denied.
NOTE: With the Remote Only method, if authentication fails due to a communication failure with the Active Directory
server automatic authentication fallback will occur to authenticate with the local user data base on the Sentry device.
To set the authentication order:
At the Sentry: prompt, type set authorder, followed by remotelocal or remoteonly and press Enter.
NOTE: Server Technology recommends NOT setting the authentication order to Remote Only until the LDAP has been
fully configured and tested.

TACACS+
The Sentry family of products supports the Terminal Access Controller Access Control System
(TACACS+) protocol. This enables authentication and authorization with a central TACACS+ server;
user accounts do not need to be individually created locally on each Sentry device.
This allows administrators to pre-define and configure (in each Sentry product, and in the TACACS+
server) a set of necessary TACACS+ privilege levels, and users access rights for each. User’s access
rights can then be assigned or revoked simply by making the user a member of one-or-more pre-defined
Sentry TACACS+ privilege levels. User account rights can be added, deleted, or changed within
TACACS+ without any changes needed on individual Sentry products.
The Sentry supports 16 different TACACS+ privilege levels; 15 are entirely configurable by the system
administrator (1 is reserved for default Admin level access to all Sentry resources).

Enabling and Setting up TACACS+ Support
There are a few configuration requirements for properly enabling and setting up TACACS+ support.
Below is an overview of the minimum requirements:
1. Enable TACACS+ support.
2. Define the IP address and domain component of at least one TACACS+server.
3. Set the TACACS+ key configured on the supporting TACACS+server.
Enabling and disabling TACACS+ support
The Set TACACS command is used to enable or disable TACACS+ support.
To enable or disable TACACS+ support:
At the Sentry: prompt, type set tacacs, followed by enabled or disabled and press Enter.
Setting the TACACS+ server IP address
The Set TACACS HostIP command sets the TCP/IP address of the TACACS+ server.
To set the TACACS+ server IP address:
At the Sentry: prompt, type set tacacs, followed by hostip1 or hostip2 and the TACACS+ server’s IP
address. Press Enter.
Example
The following command sets the primary TACACS+ server IP address to 98.76.54.32:
Sentry: set tacacs hostip1 98.76.54.32<Enter>

Setting the TACACS+ encryption key
The Set TACACS Key command sets the encryption key used to encrypt all data packets between the
Sentry and the TACACS+ server. This key must match the key configured on the TACACS+ server.
To set the encryption key:
At the Sentry: prompt, type set tacacs key and press Enter.
At the TACACS+ Key: prompt, type a key of up to 60 alphanumeric and other typeable characters
(ASCII 32 to 126 decimal). Keys are case sensitive. Press Enter. To specify no password, press Enter
at the prompt.
At the Verify TACACS+ Key: prompt, retype the key. Press Enter. To verify no password, press
Enter at the prompt.
Example
Sentry: set tacacs key<Enter>
TACACS+ Key: <Enter>
Verify TACACS+ Key: <Enter>
For security, key characters are not displayed.
NOTE: A key size of zero results in no encryption being applied which may not be supported by the TACACS+ server and
is not recommended for a production environment.
Setting the authentication order
The Set Authorder command sets the authentication order for remote authentication sessions. The
Sentry supports two methods for authentication order - Remote -> Local and Remote Only.
The Remote -> Local method first attempts authentication with the TACACS+ server and if
unsuccessful with the local user database on the Sentry device.
The Remote Only method attempts authentication only with the TACACS+ server and if unsuccessful,
access is denied.
NOTE: With the Remote Only method, if authentication fails due to a communication failure with the TACACS+ server
automatic authentication fallback will occur to authenticate with the local user data base on the Sentry device.
To set the authentication order:
At the Sentry: prompt, type set authorder, followed by remotelocal or remoteonly and press Enter.
NOTE: Server Technology recommends NOT setting the authentication order to Remote Only until the TACACS+ has
been fully configured and tested.
