just an floating idea:) not necessarily the best one... anyway, if I
think about this, the daemon listening/scanning all possible /dev/smb/*
entries is not the most effective. consider this big pts number example
-- there is no need to listen all pts entries to get the messages, just
listen those, which are actually in use.
1. idea: if smbd will handle SMB session, then it should listen on "pts"
as well - to keep session + client information consistent. and there
could be the messaging daemon, it will get message and recipient data
from smbd and will deliver the message to user. problem with this idea
is extra work for smbd to listen /dev/smb/X and to deliver message to
message daemon. since smbd and message daemon are on same host, there is
relatively little overhead with such communication.
2. idea: the message daemon will listen /dev/smb/ entries, not all, but
only entries registered by smbd. there should be registration protocol
implemented between smbd and the message daemon. problem is obvious -
what if smbd will not remove registration for sessions it handles....
