Function Documentation

gboolean inet_can_answer_ping (  void   )

Check whether we can answer a ping with a pong. Normally, when we're firewalled, we don't answer. However, if we have a non-private IP and are within a "grace period", act as if we were not: we can only know we're not firewalled when we get an incoming connection.

void inet_close (  void   )

Shutdown cleanup.

void inet_connection_attempted (  const host_addr_t  addr  )

Called each time we attempt a connection.

void inet_connection_succeeded (  const host_addr_t  addr  )

Called each time a connection attempt succeeds.

void inet_firewalled (  void   )

Called when we enter the firewalled status (TCP).

void inet_got_incoming (  const host_addr_t  addr  )

Called when we got an incoming connection from another computer at `ip'.

void inet_init (  void   )

Initialization code.

void inet_read_activity (  void   )

Called when reading activity occurred during a b/w scheduling period.

void inet_udp_firewalled (  void   )

Called when we enter the firewalled status (UDP).

void inet_udp_got_incoming (  const host_addr_t  addr  )

Called when we got an incoming datagram from another computer at `ip'.

void inet_udp_record_sent (  const host_addr_t  addr  )

Record that we sent an UDP datagram to some host, thereby opening a breach on the firewall for the UDP reply.
