If you want to hide web server string which is shown each time you perform request, this might be howto for you ;) Usual nginx response looks like that: HTTP/1.1 200 OK Date: Tue, 06 Jul 2010 08:14:19 GMT Server: nginx/0.7.67 To get rid of it you need to get source code, change it and [...]

rpaf is for backend Apache servers what mod_proxy_add_forward is for frontend Apache servers. It does excactly the opposite of mod_proxy_add_forward written by Ask Bjørn Hansen. It will also work with mod_proxy in Apache starting with release 1.3.25 and mod_proxy that is distributed with Apache2 from version 2.0.36. It changes the remote address of the client [...]

Recently I wrote short bash script to check files integrity inside directory and saw that all sums were wrong :) This couldn’t be a coincidence, so I decided to check with other tools. Well, this is what I found: $ php -r “echo md5(‘test1234′);” 16d7a4fca7442dda3ad93c9a726597e4 echo test1234|md5sum|awk ‘{print $1}’ eddc02b200ae8a15a7e6b44ac05bf5f1 Reason? Pretty simple.

From console’s point of view, restart/start/stop looks OK, but Apache2 won’t come up ad won’t bind to any port. First check if you have enough space (# df -h) and then study logs and strace output: # tail -10 f /var/log/apache2/error.log [...]

I prepared html code: <form action=”http://some.server.com/hcp/” method=”get”> <input type=”text” name=”u_firstname” value=”test”/ size=”25%” /> </form> And sent to myself as HTML using ThunderBird. Now, when I opened this email I input with default “test” text. Nothing wrong [...]

From time to time I see some scanning on my website. This usualy dies after 5 or so minutes, but it’s pretty annoying and space-consuming so I thought recently that it would be nice to get rid of those scans. An example – let say – attack looks like: ** IP ** – - [02/Jun/2010:14:35:59 [...]

This sometimes happens on Linux. You are expecting private key to be forwarded to remote host, but it’s not. Root cause here is key-agent which for gnome might be ssh-agent. It sometimes dies for no reason but resides in system as zombie process. You can “kill” zombie process, but 99,9% you will fail :) Anyways, [...]
