TALKD(8) OpenBSD System Manager's Manual TALKD(8)NAME
talkd - remote user communication server
SYNOPSIS
talkd
DESCRIPTION
Talkd is the server that notifies a user that someone else wants to
initiate a conversation. It acts as a repository of invitations,
responding to requests by clients wishing to rendezvous to hold a
conversation. In normal operation, a client, the caller, initiates a
rendezvous by sending a CTL_MSG to the server of type LOOK_UP (see
<protocols/talkd.h>). This causes the server to search its invitation
tables to check if an invitation currently exists for the caller (to
speak to the callee specified in the message). If the lookup fails, the
caller then sends an ANNOUNCE message causing the server to broadcast an
announcement on the callee's login ports requesting contact. When the
callee responds, the local server uses the recorded invitation to respond
with the appropriate rendezvous address and the caller and callee client
programs establish a stream connection through which the conversation
takes place.
