  34 <PRE>&gt;<i>I had thought of this while starting the todo discussion, but forgot about it till now.
  35 </I>&gt;<i>
  36 </I>&gt;<i>Is there any form of flood protection in services?
  37 </I>
  38      There is, but I'm not sure it works properly at the moment.  One of my
  39 goals for 5.0 is to get it working better.
  40
  41 &gt;<i>Oh and in case you were wondering, If you keep on identifying once every second,
  42 </I>&gt;<i>since a line is 110 characters long, it will take you approximately 110 days to fill up
  43 </I>&gt;<i>1 GB. I know how impossible this is, hence it is not my main concern, so please don't
  44 </I>&gt;<i>flame on this. My main point is the cluttering of the log file and services lag.
  45 </I>&gt;<i>
  46 </I>&gt;<i>For Example. As a friend so happily demostrated for me, he logged on and kept on
  47 </I>&gt;<i>identifying once or twice every second. Services didn't react, obviously, since there
  48 </I>&gt;<i>is no flood protection in it.
  49 </I>
  50      Services won't protect against this; as you yourself point out above, at this
  51 rate it would take forever to fill up your hard disk.  I do, however, see how this
  52 could get to be a problem if 100 clones do it at the same time, so I'll see about
  53 disabling logging for users who are already identified.
  54
  55      However, the main purpose of ignore is to prevent users lagging Services (by
  56 sending commands that take a long time), not to prevent the log filling up your
  57 disk space, which you can check for outside of Services using cron and ls, among
  58 others.  As such, IDENTIFY is insignificant, and things like LIST *a*b*c*d* are
  59 more of a concern.  I do agree that repeat commands are a problem, but for the
  60 time being you should be able to take care of this with ircd flood control.
