Access Control

Synchronet Access Control

Introduction

This topic covers a wide range of methods and instructions on how a Synchronet sysop can enable or restrict access to their BBS.

Host Filtering

Specific TCP/IP hosts (computers) or ranges of hosts can be restricted from accessing your Synchronet servers through the use of various filter files. Filter files may also be used to restrict specific words from being used in user-generated content (message subjects, user names, aliases, etc.).

Restricting New User Creation

The sysop can disallow remote users from creating new user accounts by setting SCFG→System→Toggle Options→Closed To New Users to “Yes”.

The sysop can restrict users from creating new user accounts to only those that know a semi-secret New User Password (NUP), by setting SCFG→System→New User Password.

Access Controls

Synchronet user accounts each have the following security/access control settings which the sysop may use to enable or restrict the user's access to specific features of functions of the BBS:

New User Values

The sysop determines which access control values will be assigned to newly created user accounts in SCFG→System→New User Values:

╔══════════════════════════════════════════════════════════╗

║ │Exemptions                                              ║
║ │Restrictions                                            ║
║ │Expiration Days            0                            ║

║ │Minutes                    0                            ║
║ │Editor                     FSEDITOR                     ║
║ │Command Shell              DEFAULT                      ║
║ │Download Protocol          None                         ║
║ │Default Toggles...                                      ║
║ │Question Toggles...                                     ║
╚══════════════════════════════════════════════════════════╝

In the above example, newly created user accounts will have:

Access Requirements

The sysop can specify combinations of access controls (e.g. security level, flags) and user values (e.g. gender, age, etc.) in SCFG (mostly under the options named “Access Requirements”) to control access to specific areas or functions of the BBS and restrict to specific groups of users.

See Access Requirements for more details.

Guest

Some sysops will want to have a Guest user account on their BBS. Guest accounts can be used to allow:

Guest Account Creation

By default, if no Guest account exists, the sysop (user with level 99) will be asked during logon to the Terminal server whether they wish to create the Guest account at that time. If the sysop answers Yes, the makeguest JavaScript module will be executed to create the Guest account with the recommended access controls:
