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++").
