SSH keys are a way to identify computers, without using passwords. If you have used git, or if you are an active participant in the open-source community, you will be definitely familiar with the important role of SSH. In the case of remote servers, when using SSH logins, the server will ask for password each time you try to login. This could be avoided by adding public key to server's authorized_keys.

Many a times while developing sites we would need to post data to an external server, for example if you have an ecommerce site and wants to manage CRM in a different server at such time you would need to pass the order details to different server. We can POST the data using CURL or drupal_http_request(). Drupal Technical POST cURL Server Leave a reply Your email address will not be published. Required fields are marked *

If you are a Nginx web server user and using Drupal as your CMS, it is quite different for redirects. Imagine that you have two websites, so if we change from an old site to a new site some of the URL will return 'Page not found'. So for that reason we can redirect them to the correct URL. If you are also looking for a 301 redirect for your Drupal site please read on. Drupal Technical Server nginx Leave a reply Your email address will not be published. Required fields are marked *

Recently we had faced a problem in a Drupal site after installing Memcached on a server with CentOS and having csf as firewall. Memcache is a process which is always running in memory and the server is configured to send automated mails regarding this process. So we need to exclude this process from csf. If you are facing the same problem in your Drupal site and want to know how to whitelist a process in csf, then read on to get the solution Drupal Technical CentOS Server memcached csf Leave a reply Your email address will not be published.

APC or Alternative PHP Cache (APC) is a free and open opcode cache for PHP. APC allows for caching of opcode generated during PHP script parsing and execution by the Zend engine.

One of the Drupal sites we maintain had recently started slowing down considerably in spite of the site mostly being static and in spite of boost set up on the server. On examination of the site we found that two things were happening on the site. One was that the site was being crawled indiscriminately by rogue crawlers. This we solved using the DDOS deflate script and setting DDOS deflate to run every 10 seconds. The second problem was that there were some bots which were continuously sending POST requests to /comment/cid/reply pages. For this we had to come up with a workaround.

You can write an infinite loop with a sleep 10 and the call to the ddos deflate script to do this.

If you run a reasonably popular site there is a very good chance that you will get crawled by unscrupulous crawlers once in a while. The regular search crawlers from the popular search engines like the Google bot, Yahoo bot, Bing bot themselves are pretty intensive when they crawl sites but they do have limits on the number of pages crawled per visit and the number of simultaneous connections opened to your server. However there are lots of unscrupulous crawlers like spam bots, email harvesting bots and even some search engines who do not set any reasonable limits on the number of simultaneous connections to your server. There are hardware solutions that are available to prevent this but they may not be affordable for everybody. There is however a simple netstat based solution to prevent DDOS.
