Accounting Features

Accounting controls keep concurrent usage, duration, speed, and total consumption within operator-defined limits.

Built-in Session Control​

Administrators define how many concurrent sessions each account may open using max_sessions.

Automatic Session Expiration​

Each session has a TTL (session_ttl_seconds). Expired sessions are terminated automatically to free resources.

Dynamic Connection Handling​

When the session limit is reached, new connections can be rejected according to policy. If an account is saturated, additional users attempting to connect can be blocked immediately.

Real-time Session Monitoring​

Active sessions are tracked and logged for auditing and operational visibility.

Rate Limiting​

Use max_speed_kbps to define per-user transfer speed limits in KB/s. Limits are applied in real time with a Token Bucket algorithm for upload and download.

Example: 1024 = 1 MB/s

Traffic Limit Enforcement​

Use max_total_mb to define total traffic caps in MB. If a user exceeds quota:

  • Access can be denied at login, or
  • An active session can be forcefully disconnected

Example: 10240 = 10 GB

Real-time Bandwidth Enforcement​

Traffic usage is checked every 1–2 seconds. When usage exceeds the defined limit, the session is terminated immediately.

Configure These Fields​

All accounting fields are set per user in Users Configuration.
