The system administrator may want to limit the number of simultaneous logons for specific User Ids. This is especially useful for ASP environments where an entire company, department or group is assigned a single User Id that everyone shares. The system administrator may want to limit the number of simultaneous connections for that company for a variety of reasons that range from server resource allocation to purchased access.
Restrictions based on the number of User Id sessions are enforced when the file gs_l_usr.txt exists. The User Id’s with connection restrictions counts are listed in the gs_l_usr.txt file. For each entry in the gs_l_usr.txt file two fields are specified: The User ID and the Count
Notice the file in the GSW UTS installation directory:
The file must reside in the Georgia SoftWorks Universal Terminal Server installation directory. T
Note: The system account must have permission to read the gs_l_usr.txt file.
It is a text file
The # character is the comment character.
Each entry must start in the first column.
Each entry consists of the User ID and the Count.
The User ID and the Count are separated by a single space.
Following are example gs_l_usr.txt file.
ACME ASP is an Application Service Provider (ASP) where they have a Specialized Database Lookup Application (SDLA) located on a server at their headquarters. They sell access to the SDLA to companies where pricing is based on the number simultaneous connections. Each company accesses the SDLA via the Internet from undetermined or varying locations. Each company that purchases access to the SDLA is provided a User ID on the ACME server, that everyone from their company shares.
Currently, AMCE has sold access to the SDLA to six companies. Four companies purchased three connections each; the remaining two companies purchased twelve connections each.
ACME only wants to restrict each company to the number of sessions that they have purchased.
The ACME System Administrator can configure the gs_l_usr .txt file that specifies the number of sessions allowed for each User ID
The Information for each company is:
| Company Name | User Id Assigned to Company | Number of Concurrent Sessions |
| BigBrain Intelligence | bbrain | 12 |
| Vigorous Investments | viginv | 3 |
| Sweet Apple Suppliers | sweeta | 3 |
| Warehouse Storage | warstore | 3 |
| Sure Shipping Co | surship | 3 |
| Wireless Security | wiresec | 12 |
This is how to set up the gs_l_usr.txt file to limit the number of connections for each company.
Edit the file gs_l_usr.txt and add the following lines. (Be sure to start in column one)
Each time a logon request occurs the GSW Universal Terminal Server determines the number of active sessions associated with that User ID. If the count of active sessions exceeds the configured count in the gs_l_usr.txt file then the logon is denied.
A sample gs_l_usr.txt file with examples is installed with the software. It can be easily modified and used for your purposes
