I recently needed to have a look at moving some services to a different VPS provider for redundancy so I decided to benchmark my options to compare them. The plan selected was whichever had 16GB of RAM (though Google is 15GB). The selected datacenter was always London (Azure only says… Continue reading
I couldn’t find proper instructions on doing this anywhere so here are mine: In your OSSIM portal go to Environment -> Assets & Groups -> Add Assets and enter the name/IP of the asset you want to add. On the agent run: yum -y install libevent-devel pcre2-devel openssl-develwget https://github.com/ossec/ossec-hids/archive/3.6.0.tar.gztar xzf… Continue reading
I was looking at VPS providers for batch video encoding runs. These numbers are in no way a comprehensive test, I was just surprised by some of them so I thought I’d share. My source file is a 04:17 1080p mp4 and I ran it through HandbrakeCLI to create an… Continue reading

PHPmailer does not work with NTLM authentication and insists on using mhash() which is deprecated – so you need to edit the file in /extras called ntlm_sasl_client.php Find the code that checks if mhash() is installed and replace the 3 mhashes with hash instead: || !function_exists($function = “mhash”) ) {… Continue reading
Fail2ban hasn’t been working for me, I still have people running brute force attacks on my Postfix server, so I though I’d rig up something myself. This consists of a bash script that identifies multiple failures and bans them, run on cron every 10 minutes. It checks for both smtp… Continue reading
Just a quick one – I needed a script to convert a table to a csv, so this is what I came up with. See the annotations for notes: //html table is in variable $report $report = str_replace(array(“\n”, “\r”), “”, $report); //remove existing line breaks $report = str_replace(‘”‘, ‘\”‘, $report);… Continue reading
