    Exclamation Apache servicing third party requests??


    Hi,

    I recently installed a apache2.2 in ubuntu 8.04 server.
    After that load became very high on our server, then i ran apachetop in our server.
    We are running sites based CMS like Zope and Plone.
    The output which is shown by apachetop doesnt contain a single request of our sites.
    All are some third party requests.


    Code:
    last hit: 12:38:43         apachetop runtime:  0 days, 00:00:39             12:38:44

    When i looked thru the Apache access.log it was full of 404 and 200 error messages for GET requests.

    What can i do to reduce these third party requests and speed up my Apache ?

    PS: I now configured cache module in Apache to cache pages which has a significant change on the speed but the apachetop output still displays the non relevant sites only

    hello,

    you can block some ips that use lot of resources .. such as use an netstat -anp in redhat but not sure about ubuntu and install an APF or CSF firewall that will reduce hits on the server so that the server is safe from brute force ..etc
    Regards
