The 'no-configuration, only-active-when-needed' SSH VPN

Post date: April 13, 2005, 03:04 Category: Network Views: 3372 Comments
Tutorial quote: So, we started thinking about how we might set up a VPN between the application server and our internal software mirror. The only requirement is that the VPN be initiated from the "inside-out" and that the connection is only active for as long as we need to use. In other words, it would only be active during an administration session. Ideally, it wouldn't be a lot of work to setup and tear down either.

SSH to the rescue...

Fortunately, SSH client and server come with support for this out of the box, requiring no additional software to be installed, and no configuration changes. On the server side, sshd, the setting "AllowTcpForwarding" defaults to "yes" unless your sshd_config file explicitly disables it. On the client side, all you have to do is request the forwarding.

Delete Qmail Server messages Queue

Post date: January 12, 2007, 18:01 Category: Software Views: 3391 Comments
Tutorial quote: qmail is a mail transfer agent that runs on Unix. It was more secure replacement for the popular Sendmail program. The author offered a $500 prize for the first person to publish a verifiable security hole in the latest version of the software.

This is a useful thing to do in a number of situations. For instance, if you are hit with a spamming attack, you can temporarily instate a second Qmail installation (once the spam run is finished), allow it to take over mail receipt,and then use this tool to clean the offending mails out of the queue before switching over to the main Qmail installation once again.

Installing Tomcat6 With SUN-Java & Apache2 Integration On Ubuntu 10.04

Post date: February 2, 2011, 13:02 Category: Installing Views: 3164 Comments
Tutorial quote: Apache Tomcat (or Jakarta Tomcat or simply Tomcat) is an open source servlet container developed by the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a "pure Java" HTTP web server environment for Java code to run. Tomcat should not be confused with the Apache web server, which is a C implementation of an HTTP web server; these two web servers are not bundled together. Apache Tomcat includes tools for configuration and management, but can also be configured by editing XML configuration files.

How To Install Qmailtoaster (CentOS 5.3)

Post date: June 19, 2009, 10:06 Category: Installing Views: 8334 Comments
Tutorial quote: Qmailtoaster is a project that aims to make the installation of Qmail onto RPM based systems a snap. All of the packages are distributed in source RPMs so building the packages for your particular distro and architecture is as easy as running a script or a simple command for each package. The RPMs have all of the needed and commonly asked for patches included so you can have a mail server up and running in about an hour. When it's all complete, you'll have a full Qmail mail server installation ready for just about anything. I personally run Qmailtoaster servers for other companies and ISPs who have tens of thousands of users on their systems.
