IASTools 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: up to 255 IP-Pools can be assigned (IP-Pools are a range of IP addresses
that are passed to the user when they log onto the network). By blocking IP addresses
at various points on the network, administrators can control the amount of access the
user is permitted. | |
• | Limited Group Logon: again up to 255 groups can be assigned. Each group is permitted
a specified number of users to be logged on at one time. | |
• | Session Control: This feature allows for the control of how many times a user/s can
be logged on with the same username and password. In some instances more than one session may
be desirable, i.e. when users use multilinks for the connections. In most cases the user
should only be permitted one session (the username and password should only allow access
if there are no currently logged on users, who used the same username and password). Local
groups can be set to permit two sessions, three sessions, etc. Depending on the which
group the user is a member of, dictates the number of times the username and password
will permit access concurrently. | |
• | Logging: Logs of the current state of the NAS boxes and/or connection logging, can be
sent to an ODBC enabled database. Two ODBC syntax types are supported which should permit operation
with just about any ODBC database. The type of database is a crucial factor in IASTools performance. | |
• | Event Log: The State server makes use of the event log to report errors or
violations. The ODBC logging can also be used to log violations. | |
• | Testing Tools: Tools enabling the easy testing of the various elements
should reduce setup time. | |
• | Debug Mode: This mode allows for details of the State Server to
be sent to a console window enabling rapid deployment. | |
|
All of the above features, except logging, are implemented by applying themselves to Local User Groups on your
Domain Controllers (or Active Directory). When the features are added, you will be
asked to select a Local Group . Any user belonging to the group will have the feature
applied to them when they dial-in. This should permit simple integration with existing software. Any number
of Domain Controllers and IAS Servers are supported.
The State Server runs as a service, which means that the State Server will
start when the server boots and does not require a user to log onto the server.
It has two levels of logging, connection logging, and state and connection logging.
In connection logging the dial-in and hangup are logged, with details.
State logging logs which user is logged onto which port and on which NAS at this moment in time.
SSTune has been included in IASTools to enable the fine-tuning of the IAS Dll plug-in as well as
load testing. This would permit the administrator to calculate the number of IAS
servers the State Server can handle with the current network configuration and database
options.
IASTools accommodates a distributed network. This offers redundancy. Multiple NAS boxes
and IAS servers results in a high quality of service as the network is not dependent on
any one system for operation. IASTools State Server has been designed to permit network
operation to continue in the event the State Server is unavailable. IASTools never
permits access, it only denies access if one of the components is violated. In the case
of IP-Pools, the State Server is responsible for offering the NAS an IP address to give to
the client. In the event the State Server is unavailable your domain controller will
be solely responsible for permitting or denying access and the IP address will be that
specified by the NAS. Thus, even if the State Server is not available, the dial-in network
can still function.
IASTools 2.0pre1 Beta - New Features
|
1. | Support for up to 512 NAS server.
| |
2. | Local and Global group support.
| |
3. | CalledStationID and CallingStationID now present.
| |
4. | State Explorer allows for the viewing of stats on the StateServer and also
info on each port in use (does not require ODBC logging).
| |
5. | Improved network communication.
| |
6. | Fewer parameters to set in SSTune.
| |
7. | Support for single table session storage with ODBC.
| |
8. | Improved SQL performance. Better burst performance has been achieved. Slow
SQL servers will make less of an impact on the StateServers performance.
| |
9. | Access list to improve security.
| |
10. | Session time-out abilities.
| |
11. | HelpDeskClient allows help desk users to better support the client base.
| |
12. | Users can now select a DataSource name, username and password.
| |
13. | SSTune now also includes a State Test as well as a Stress Test. These
tools will help access server performance and correct operation.
| |
14. | Web Interface: Allows the state of the State Server to be viewed through a
web browser. Stale sessions can also be cleared through the interface.
| |
15. | ActiveX component: Allows a programmer to interface a custom application
to view the state of the State Server and to clear stale sessions.
