====== List webserver information ======

In case you want to determine webserver and OS information for a given site use curl or wget.
Some sites will reveal a lot of information some is not so informative.

  # curl -I http://<domain>

  # wget --server-response --spider http://<domain>

https can be used as well

If curl or wget is not installed telnet can be used as well

  # telnet <domain> 80 (or 443 is https is used)

Type
  HEAD / HTTP/1.0
Hit enter twice

====== Hide webserver information ======

Change your servers php.ini expose php parameter to:\\
  expose_php Off

Change/add following httpd.conf parameters:\\
  ServerTokens Prod
This will only reveal Apache in return.

====== List IP's after number of hits ======

  awk '{print $1}' accept.log | sort  | uniq -c | sort -n

====== List Apache requests per day ======
  
  awk '{print $4}' accept.log | cut -d: -f1 | uniq -c
  
====== List Apache requests per hour ======

  grep "22/Nov" accept.log | cut -d[ -f2 | cut -d] -f1 | awk -F: '{print $2":00"}' | sort -n | uniq -c
