RRASTools Features
For ISPs, control over what the user is capable of doing is crucial. To this end the
following features have been added to IASTools:
|
• | IP-Pools: RRAS only supports one IP-Pool from which all dial-in users are assigned an
IP address. Having more IP-Pools enables you to restrict and control the access a user
has to your network and your valuable resources. RRASTools extends the number of IP-Pools
to 255. Far more than you will probably ever require.
| |
• | Limit Logon Group: RRAS does not allow you to control how many modems, groups of
users, may use. By limiting the number of modems a group of users can use, you have the
ability to control how your modems are used. Low priority groups can now be restricted
from exploiting valuable resources. ISP's are now empowered to offer more flexible
contracts to organizations.
| |
• | Limit Time Access: 'User Manager for Domains' offers a 'Time Access Restriction', but
the restriction is applied on per user basis, it is also not present if the server is
setup as Stand Alone. The 'Limit Time Access' feature in RRASTools is applied to a group,
making setup time shorter, and is available to Stand Alone servers.
| |
• | Concurrent Access: RRAS administrators have up to now been open to exploitation by
their clients. Users can logon more than once with the same username and password at
the same time. RRASTools offers a simple solution to prevent concurrent logons.
| |
• | Speed Access Restriction: ISDN and analog modems can easily sit side by side on a
RRAS server. The problem comes in when you want to control which of your users can use
the ISDN modems and which are permitted only analog access. RRASTools offers the ability
to control which users can logon with speeds of 64kps and which can only use the analog
modems. The implementation does not prevent the use of ISDN modems (like the US Robotics
Courier I-Modem) which can provide V90, X2, ISDN, and V34, from being used only as ISDN
or Analog modems. The speed the user connects at is checked, if they have 64kps
negotiated then RRASTools will check to see if the user is in a group permitting
64kps access. All ISDN links 64K, 128K, 192K, 256K etc can be controlled with this
component and the Multilink component.
| |
• | Multilink Control: Multilinks allow a user to use two or more modems to connect to the
server. This increases the user's bandwidth. Multilinks can be both ISDN and analog.
RRASTools allows you to select the number of multilinks the user is permitted. Multilinks
enable ISDN speeds of 128K, 192K, 256K etc by bundling 64K connections. In a similar
fashion 112K, 168K etc analog links are established by bundling 56K analog connections.
Without the component installed any number of mutilinks can be created by the user. Once
installed all users will only be permitted one link unless otherwise specified.
| |
• | Logging: Logging to an ODBC database (SQL, MS ACCESS, FoxPro etc) and text files has
been included.
| |
• | Modes: Support for authenticating from both a PDC on the primary domain, and for
Stand Alone Servers.
|
All the features are applied to local groups in your 'User Manager' ('Computer Management'
with Win 2000). Adding a user to the group binds the feature to the user. In other words
a local group in your 'User Manager' could have a time access feature applied to it. All
users in the group will be tested to see if they are permitted access, specified in the
time access feature. If so they logon, if not the connection is refused. Not all features
only permit or deny access, the IP-Pool feature allows for characteristics of the
connection to be controlled.
