Interpreting database-import log files

Unlike IAS-formatted log files, database-import log files present the data in a standard sequence and use a structure that is identical, regardless of the network access server (NAS) that sends the data. This consistent sequence and structure helps simplify accounting and authentication records. Data can be easily exported to a database.

Note

  • Although IAS supports both IAS-formatted and database-import log files, the database-import log format should be used in most instances because it supports the use of ODBC-compliant tools.

Entries recorded in database-import log files

The following are example entries (Access-Request and Access-Accept) from a database-import log file.

"CLIENTCOMP","IAS",06/17/1999,13:04:33,1,"client",,,,,,,,,9,"10.10.10.10","iasclient",,,,,,,1,,0,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

"CLIENTCOMP","IAS",06/17/1999,13:04:33,2,,"iasclientdc/Users/client",,,,,,,,9,"10.10.10.10","iasclient",,,,,,2,1,"Allow access if dial-in permission is enabled",0,"311 1 10.10.10.11 06/17/1999 20:04:30 1",,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

The following table shows the attributes that can be contained in a record in the database-import log file, the sequence in which they are recorded, and how the example above is interpreted.

Notes

  • A blank field in the first column indicates that the NAS did not include the attribute in the packet (in the example entry).

  • The Data type column identifies the data type (text, number, or time) for each attribute. When you create a database into which log files are imported, you must define each field for the data type of the attribute value that will be imported into it. In database-import log files, text values (such as strings, octet strings, and IP addresses) are always surrounded by double quotes. If the double quotes appear within the string, then they are replaced with a double set of double quotes.

  • This table shows the values for the IAS-internal attribute.

  • To help read and interpret the database format log files, the Iasparse tool is included in the Using the Windows Deployment and Resource Kits. This tool can be used to parse log files and provide output in a readable format.
