What do the DC++-style tags mean?
Notation
The following information appears in the
Tag column for every
user in the user list of the Hub window:
<++ V:x,M:x,H:x/y/z,S:x[,O:x]>, where
- V(ersion)
- x = client version
- M(ode)
- x = mode (A = Active, P = Passive, 5 = SOCKS5)
- H(ubs)
- x = number of hubs connected to where you're not a
registered user
y = number of hubs you're registered in
z = number of hubs you're registered as an
operator
- S(lots)
- x = number of upload slots you have open (note that
they may be in use already)
- O(pen an extra slot if speed is below)
- x = if total upload is below this value DC++ will
open another slot
This part of the tag is only shown when the option for
it is enabled.
The tag is updated every 1-2 minutes if there are changes.
Other clients may introduce more tag elements such as L:x
or B:x which means usage of upload bandwidth limiter where
x is the amount of maximal upload bandwidth in KiBs.
History
The DC++ tag was introduced back when the only
available Direct Connect client was Neo-Modus DirectConnect
(NMDC) v1.0. That particular client could only connect to one
hub at a time, which ensured that the upload slots available
were assigned to other users connected to that hub. At first,
hub owners considered DC++ to be a cheat client, because it
could connect to multiple hubs at once. The DC++ tag was
introduced so hub owners could check if the users were
connected to a reasonable amount of hubs and had enough upload
slots available for sharing.
At this point, almost every client, whether it's capable of
joining multiple hubs or not, has a similar tag in it's
description field. The custom is to replace "++" with some
other identifier uniquely identifying the client type (common
are "StrgDC++", "ApexDC++" and "RSX++").
