The following configurations represent typical/commonly used server configurations.

In addition, to any of them, it is possible to further specify:

• the listening local network interface (-i <LOCAL_IFACE_IP>)
  • default: listens on all local network interfaces
• the listening TCP port (-p <PORT>)
  • default: 443
• the credentials, used for client authentication (-up <USERNAME>:<PASSWORD>)
  • default: randomly generated (username; password)
• the predefined X.509 certificate (-c <X509_CERT_PATH>)
  • default: randomly generated, self-signed
• the randomly generated self-signed X.509 certificate's Common Name (-cn <TEMP_X509_CN>)
  • default: OS hostname
• the web root directory (-w <WEB_ROOT_PATH>)
  • default: current directory (from which barabbas is invoked)
• the IP address(es) of allowed clients (-a <CLIENT_IP_ADDR_1>,<CLIENT_IP_ADDR_2>,...,<CLIENT_IP_ADDR_N>)
  • default: allows connection from any IP address

All commands require modifying variable values, marked with angle brackets (e.g. -p <PORT> ➔ -p 80).
