|
<usage>
|
|
<p>This directive enables <a href="http://www.ietf.org/rfc/rfc1413.txt"
|
|
>RFC 1413</a>-compliant logging of the remote user name for each
|
|
connection, where the client machine runs identd or something similar.
|
|
This information is logged in the access log using the <code>%...l</code>
|
|
<a href="mod_log_config.html#formats">format string</a>.</p>
|
|
|
|
<note>
|
|
The information should not be trusted in any way except for
|
|
rudimentary usage tracking.
|
|
</note>
|
|
|
|
<p>Note that this can cause serious latency problems accessing
|
|
your server since every request requires one of these lookups
|
|
to be performed. When firewalls or proxy servers are involved,
|
|
each lookup might possibly fail and add a latency duration as
|
|
defined by the <directive module="mod_ident"
|
|
>IdentityCheckTimeout</directive> directive to each hit. So in
|
|
general this is not very useful on public servers accessible from
|
|
the Internet.</p>

|
|
<usage>
|
|
<p>This directive specifies the timeout duration of an ident
|
|
request. The default value of 30 seconds is recommended by <a
|
|
href="http://www.ietf.org/rfc/rfc1413.txt">RFC 1413</a>, mainly because
|
|
of possible network latency. However, you may want to adjust the
|
|
timeout value according to your local network speed.</p>
