10 Talkd is the server that notifies a user that someone else wants to ini‐
11 tiate a conversation. It acts a repository of invitations, responding to
12 requests by clients wishing to rendezvous to hold a conversation. In
13 normal operation, a client, the caller, initiates a rendezvous by sending
14 a CTL_MSG to the server of type LOOK_UP (see ⟨protocols/talkd.h⟩). This
15 causes the server to search its invitation tables to check if an invita‐
16 tion currently exists for the caller (to speak to the callee specified in
17 the message). If the lookup fails, the caller then sends an ANNOUNCE
18 message causing the server to broadcast an announcement on the callee's
19 login ports requesting contact. When the callee responds, the local
20 server uses the recorded invitation to respond with the appropriate ren‐
21 dezvous address and the caller and callee client programs establish a
22 stream connection through which the conversation takes place.

26 /var/log/talkd.log.
27 [-p] Packet logging mode; writes copies of malformed packets to
29 /var/log/talkd.packets. This is useful for debugging interoperability
30 problems.
