File Format and Rules > NT Format:

The following NT filtering profile files can be set up:

  • User - ntuserprofile.conf
  • Group - ntgroupprofile.conf
  • Quota - quota.conf

Each filtering profile included in the file should be entered on a separate line. Filter options should be included at the end of the profile string, unless this is a quota file, in which instance the quota is included at the end of the profile string. (See Quota for rules on setting up a quota file.)

Filter Option Codes
• 0x1 = Exception URL Query (always enabled)
• 0x2 = X Strikes Blocking
• 0x4 = Google/Yahoo!/Ask.com/AOL Safe Search Enforcement
• 0x8 = Quota Query
• 0x100 = Search Engine Keyword
• 0x200 = URL Keyword
• 0x400 = Bypass Minimum Filtering Level for Override Account
• 0x1000 = Extend URL Keyword Filter Control

NOTE: To enable multiple filter codes, add the codes together. For example, to enable all features for an NT profile, enter 0x1307 at the end of the profile string. To disable all filter codes for an NT profile, enter 0x1 at the end of the profile string.

Category Command Codes
Category command codes must be entered in the following order: J, R, M, I. “PASSED” should either be entered after J, R, or M, or after a string of category codes following J, R, or M.

J = Positioned before the category/categories defined as "always allowed."
R = Positioned before the category/categories defined as "blocked."
M = Positioned before the category/categories defined as containing URLs potentially against the organization’s policies, and accompanied by a warning message.
I = Positioned at the end of a profile string, indicating that all other categories should “pass.”
PASSED = When positioned at the end of a string of categories or after a category command code, this code indicates that unidentified categories will follow suit with categories defined by that code: J (pass), R (block), or M (receive warning message).

NT User Filtering Profile File Format
When setting up the ntuserprofile.conf file, each entry must consist of the username, and either a rule number or rule criteria (port, category, and filter mode specifications). A redirect URL can be included, if a specific URL should be used in place of the standard block page. If a redirect URL is not included, a blank space should be entered in its place in the profile string. Segments of the profile string should be separated by commas (,). The filter option designation should be placed at the end of the profile string. For example:

JSmith, Rule1, , 0x6
Jane_Doe, Rule0, http://www.logo.com, 0x1
Doe-John, A, J R M CHAT KDPORN FINAN GGAMES GPORN I, 1, , 0x204

NT Group Filtering Profile File Format
When setting up the ntgroupprofile.conf file, each entry must consist of the group name, and either a rule number or rule criteria (port, category, and filter mode specifications). A redirect URL can be included, if a specific URL should be used in place of the standard block page. If a redirect URL is not included, a blank space should be entered in its place in the profile string. Segments of the profile string should be separated by commas (,). The filter option designation should be placed at the end of the profile string. For example:

Admin, Rule2, , 0x302
Sales, Rule1, http://www.cnn.com, 0x2
Tech, A, J R CHAT FINAN GGAMES M I, 1, , 0x300
