I am trying to debug an issue with Apache 2.4 on Debian 8 (jessie). I notice lines like the following in my
[Sun May 15 11:53:10.526964 2016] [authz_core:error] [pid 14805] [client 18.104.22.168:43595] AH01630: client denied by server configuration: /var/www/html/admin/
[client] block, what does the part
:43595 means? I would guess it's a port number, but I am not sure since it doesn't appear in Apache documentation and it's not described in
/usr/share/doc/apache2/README.Debian.gz either. I also tried to find if the log format isn't customized somewhere, but
grep -rnw '/etc/apache2/' -e 'ErrorLogFormat' returns nothing.
