Stop Logging "Internal dummy Connection" in Apache

Apache 2.x keeps child processes alive by creating internal connections which appear in the log files as "internal dummy C Onnection "On the IP Address:: 1 or 127.0.0.1. If you ever monitor Apache log files you'll see a lot of these in the log files. This post shows the Prevent logging for these the IP addresses so your log files won ' t get filled up with these

What's the log lines look like

With IPv6 the log lines come from the IP address:: 1 and would look similar to this:

1	::1 - - [11/Oct/2010:13:02:47 +1300] "OPTIONS * HTTP/1.0" 200 - "-" "Apache/2.2.9 (Debian) PHP/5.2.6-1+lenny9 with Suhosin-Patch mod_ssl/2.2.9 OpenSSL/0.9.8g (internal dummy connection)"

Prevent Logging for local requests

The simplest solution is to prevent logging for local requests. Normally these would only being from the Apache server itself, unless your is doing something special which is requesting Pag Es using the local IP address (i.e.:: 1 or 127.0.0.1).

Locate The logging section of your main Apache log file. You'll have a entry something along the lines of this, although the exact setting would vary depending on which operating System, distribution and version you is using, or any custom changes you have made:

1	CustomLog /var/log/apache2/access.log combined

Add this to IPV4 style IP addresses for local connections (127.0.0.1):

1	SetEnvIf Remote_Addr "127\.0\.0\.1" dontlog

Or this for IPV6 style IP addresses (:: 1):

1	SetEnvIf Remote_Addr "::1" dontlog

And then add Env=!dontlog to the end of your logging line so it looks like this, using the same example as shown above:

1	CustomLog /var/log/apache2/access.log combined env=!dontlog

Now restart Apache and any local connections, including those "internal dummy connection" entries, would no longer be Logge D.
