Padre Still Crashes on Debian Linux

The linked post was written in 2012 explaining what I think most users of Padre encounter, and therefore I won’t repeat anything already nicely documented there except to quote “And please do not feed me a junk line about it works on my Linux distribution, I do not care. Pretend I am a normal end user for a moment. If...

Apache Permissions on ServerRoot Directories

Apache Permissions on ServerRoot Directories In typical operation, Apache is started by the root user, and it switches to the user defined by the User directive to serve hits. As is the case with any command that root executes, you must take care that it is protected from modification by non-root users. Not only must the files themselves be writable...

Setup SSH for Accessing Remote Server Without Password

On the Remote Server Logged in As User or as root but in users home sudo mkdir ~/.ssh sudo chmod 700 ~/.ssh && chmod 600 ~/.ssh/* On you local (desktop) assuming you have already created your GPG Keys cat ~/.ssh/id_rsa.pub | ssh root@example.com 'cat – >> ~/.ssh/authorized_keys'

How To Manage Fail2ban Using Perl Script On Remote Servers and A Control Mysql Database

Earlier I posted how to use a text file created by a script to similarly manage the rogue IPs that Fail2ban bans. The problem with using scripts and crontab is that it is not reporting in real-time. The method here works in real-time because Fail2ban reports directly to the MySQL on the control server. On each remote you’ll want to...

Fail2ban Mysql Database to Manage Persistent Bans

Step 1 Create Database and Tables in MySQL Add a “source” field for the server name if you want to use a remote database setup (and add it to the UNIQUE KEY). The UNIQUE KEY prevents duplicates of course. But this means you can refresh the perl script without handling duplicates there which would complicate things considerably. CREATE TABLE iptable...

SEO Sitemap

What is a sitemap? A sitemap is a exactly what it says, a map of pages you want the search engines (and people) to know about. Generally they are for search engines to quickly read and index your site. A sitemap is more important for a new website or for a site with poorly designed navigation. But it is widely...

Start Reverse Tunnel on boot using autossh for Debian 7

As usual, most of the how-to guides out there are too brief (I’m guilty) or apply to other distros: This works on Linux Debian 7 all-around, and this is a complete how to. It works. You just have to follow a very long thread. No A.D.D. here! We will create a Persistent Reverse SSH Tunnel between 2 machines using autossh....

Block All Traffic to Your New Remote Server

I block all traffic to a new server while I setup users and environment using Netfilter AKA iptables. Nothing else gets in or out of the box but me. This requires 2 scripts actually. One to close the machine to all other IPs but mine, and one to “unblock”. You need to unblock while installing other software, re. LAMP, when...

How to Edit the DNS of your Domain Name

This is how to Edit the DNS of your Domain Name (example here is for GoDaddy) The general method is similar at most hosts. An “A record” connects your domain name to your server IP address. This is what allows users to type your domain name in a Web browser to access your website. The DNS (domain name service) translates the...

BASH Shell Notes
