Access Control

Synchronet Access Control


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:

  • Level: a value (a.k.a. security level) between 0 and 99, with level 90-99 being reserved for operators of the system (sysops/co-sysops)
  • Flags: 4 sets of 26 sysop-defineable toggle flags (A-Z) which allow for customized access control
  • Exemptions: 26 flags (A-Z) which have pre-defined functions to exempt the user from specific limitations
  • Restrictions: 26 flags (A-Z) which have pre-defined functions to restrict the user from using specific features/functions
  • Expiration: a date a which time the user account will be automatically deleted (regardless of inactivity)
  • Credits: a balance of credit which the user can deposit into (e.g. by uploading files) or withdraw from (e.g. by downloading files)
  • Minutes: a balance of time which the user can use to go beyond their normally limited time per/call or per/day (a.k.a. time bank)

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.
