<pre wrap="">Hi!
Do you still have occasional slow connections to ftp on BO?
I've found out that "IdentLookups off" does not really work in "server
config" but works correctly in "<Global>" as well as in "<VirtualHost>".
If this is something you've seen or still see, comment on this as I'm
pondering fixing this once and for all now.

<pre wrap="">Hi Rickard,
I have never seen this as a problem, but we are fortunate to run a very
stable DNS service, and most of the ISP's here are good about providing
PTR's on their networks.
However, I can see where it could become a problem if you have many
users without proper reverse-DNS set up. In that case, the lookups will
have to time-out. So I can see where disabling that could be helpful.

<pre wrap=""><!---->Hi Chris,
it's not UseReverseDNS I'm talking about, it's the old and trustworthy
auth/identd (tcp/113) which nobody uses anymore as nobody in their right
mind opens tcp/113 in their firewall. :)
So, the question is, should we force this off or make it optional?

I believe the main problem is the difference in how most SoHo- to
Enterprise-Firewalls as well as "personal Firewalls" handle connections
to 113: Most of them silently drop the packet instead of rejecting it
visibly with an ICMP message which would be the proper response in a
unix-like world and would not cause any delays as if identd would have
properly replied. <br>
Anyway, as the information from identd is probably never ever used: I
would vote for disabling lookups completely, I know identd lookups just
as a source of timeouts and problems, haven't ever used them for
anything useful in the last 20yrs and I bet thats the same for most
BO-users and -admins.<br>
<br>
1 vote for force to off.<br>

Cheers,<br>
