ΓòÉΓòÉΓòÉ 2. Web Manager Configuration Help ΓòÉΓòÉΓòÉ
The Web Manager Configuration program enables the user to configure and control
the security features of the Netfinity* Manager for Web service.
User-selectable options are:
o Enable or Disable the Web Manager
o Set the Web Server Socket for the Web Manager
o Restrict the remote hosts which will be permitted to interact with the
Web Manager
ΓòÉΓòÉΓòÉ 3. Save Button ΓòÉΓòÉΓòÉ
Save any changes of the Web Manager Configuration. All changes, except for
changes to the web server socket number, take effect immediately. Changes to
the web server socket number will take effect only after NETFBASE.EXE has been
restarted.
ΓòÉΓòÉΓòÉ 4. Web Manager Enabled ΓòÉΓòÉΓòÉ
Selecting this radio button will cause the Web Manager to be activated once the
configuration is saved.
ΓòÉΓòÉΓòÉ 5. Web Manager Disabled ΓòÉΓòÉΓòÉ
Selecting this radio button will cause the Web Manager to be deactivated once
the configuration is saved.
ΓòÉΓòÉΓòÉ 6. Web Server Socket ΓòÉΓòÉΓòÉ
The Web Server Socket field allows setting of the TCP/IP socket number which
will be used by the Web Manager. Most web servers default to a socket number
of 80. Web Manager defaults to a socket number of 411, in order to avoid any
conflict with other web servers which the user might have installed. Any socket
number from 1 to 32767 is useable, but the user should be careful to avoid
conflict with other TCP/IP applications.
If a socket number other than 80 is used, most web browsers will require the
user to provide the socket number when accessing the Web Manager. To provide
the socket number, the user should append a colon followed by the socket number
to the host address of the Web Manager system. For example, to access the main
page of the Web Manager on host test.raleigh.ibm.com, the user should enter
http://test.raleigh.ibm.com:411/main if the Web Manager is configured to use
socket 411. If the Web Manager is configured to socket 80, the user could
optionally omit the :80.
Note: If you change the web server socket number, you must restart
NETFBASE.EXE for the change to take effect.
ΓòÉΓòÉΓòÉ 7. Any Remote Host ΓòÉΓòÉΓòÉ
Activating this radio button will allow the Web Manager to be accessed from a
web browser located at any TCP/IP address. The accessing user will still be
required to enter any necessary user-ids and passwords.
ΓòÉΓòÉΓòÉ 8. Specific Remote Hosts ΓòÉΓòÉΓòÉ
Activating this radio button will restrict the Web Manager to only accepting
access requests from specific TCP/IP hosts. Once set, only systems with one of
the TCP/IP addresses provided by the user will be allowed to attempt access to
the Web Manager. Any request coming from a system not specified by the user
will be automatically rejected, whether or not a valid user-id and password is
provided.
The authorized systems can be defined individually (by name or address), or by
ranges of TCP/IP addresses.
A user attempting access from an authorized address still must provide any
required user-id and password information in order to access the Web Manager.
ΓòÉΓòÉΓòÉ 9. Authorized Host List ΓòÉΓòÉΓòÉ
The Authorized Host List shows all of the individual TCP/IP hosts, and TCP/IP
address ranges, which have been authorized to access the Web Manager.
To edit an entry in the Host List, double-click on the desired entry (or
highlight the choice and press the Enter key).
To delete an entry, highlight the choice and activate the Remove Button.
To add a new entry, activate the Add Button.
ΓòÉΓòÉΓòÉ 10. Add Button ΓòÉΓòÉΓòÉ
The Add Button allows the user to define a new authorized host or range of
TCP/IP addresses.
ΓòÉΓòÉΓòÉ 11. Remove Button ΓòÉΓòÉΓòÉ
The Remove Button allows the user to delete an authorized host or range of
TCP/IP addresses from the Authorized Host List. Deleting an authorized host or
range of TCP/IP addresses will prevent future accesses to Web Manager from the
given TCP/IP hosts.
ΓòÉΓòÉΓòÉ 12. Restore Button ΓòÉΓòÉΓòÉ
The Restore Button will immediately reset the Web Manager Configuration display
back to the setting defined when the configuration was last saved using the
Save Button.
ΓòÉΓòÉΓòÉ 13. Exit Button ΓòÉΓòÉΓòÉ
The Exit Button will cause the Web Manager Configuration service to terminate.
ΓòÉΓòÉΓòÉ 14. Add/Edit Authorized Host ΓòÉΓòÉΓòÉ
This panel can be used to define or modify entries in the Authorized Host List.
The user can either define a single host name or address or define a range of
TCP/IP addresses.
To define a single host name or address, select the Authorize Specific Host
radio button, and enter either the host name or the dotted-format TCP/IP
address for the system to be authorized in the Host Name or Address field.
Since it is possible for an intruder to emulate a name server in order to
"borrow" a system's name, using the dotted-format TCP/IP address is recommended
for maximum security.
To define a range of addresses, select the Authorize Address Range and enter
the low and high ends of the TCP/IP address range using the dotted-format
TCP/IP addresses. This will allow access to be attempted from any system whose
address is at or above the lower IP address and at or below the higher IP
address.
ΓòÉΓòÉΓòÉ 15. Authorize Specific Host ΓòÉΓòÉΓòÉ
Select this control in order to authorize a single host name or address.
ΓòÉΓòÉΓòÉ 16. Host Name or Address ΓòÉΓòÉΓòÉ
This field defines the host name or dotted-format address of the single host to
be authorized.
ΓòÉΓòÉΓòÉ 17. Authorize Address Range ΓòÉΓòÉΓòÉ
Select this control in order to authorize a range of TCP/IP addresses.
ΓòÉΓòÉΓòÉ 18. Low IP Address ΓòÉΓòÉΓòÉ
This field defines the lower bound of an authorized TCP/IP address range. Its
contents must be a dotted-format address, such as 9.67.68.22.
ΓòÉΓòÉΓòÉ 19. High IP Address ΓòÉΓòÉΓòÉ
This field defines the upper bound of an authorized TCP/IP address range. Its
contents must be a dotted-format address, such as 9.67.68.22.
ΓòÉΓòÉΓòÉ 20. OK ΓòÉΓòÉΓòÉ
Selecting this button will cause the user's inputs to be validated. If the
inputs are correct, the entry will be added or updated in the Authorized Host
List.
ΓòÉΓòÉΓòÉ 21. Cancel Button ΓòÉΓòÉΓòÉ
Selecting this button will cancel any changes to the Authorized Host List, and
return the user to the Web Manager Configuration main window.
ΓòÉΓòÉΓòÉ 22. URL Log CheckBox ΓòÉΓòÉΓòÉ
Selecting this checkbox will enable logging to a file called "webfin.log" in
your Netfinity directory. Each request made to the web server will be recorded
in the form of a plain text URL. In addition, the Intel byte order IP address
of the requesting machine, and the time/date stamp of the request are also
logged. Since many parameters are sent over the url, sensitive data could
potentially be logged (such as passwords), so users should be careful to secure
the machine against possible tampering.
Note: If you change the web server socket number, you must restart
NETFBASE.EXE for the change to take effect.
Note: The logging action takes care to remove passwords from the log that are
entered through the security service. However this does not prevent a user
from entering a password and having it logged by other services, such as while
setting up an alert action to export alerts to a database.
