Chkrootkit Portsentry Howto

Post date: April 15, 2005, 23:04 Category: Security Views: 3195 Comments
Tutorial quote: This document describes how to install chkrootkit and portsentry. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems.

Chkrootkit "is a tool to locally check for signs of a rootkit" (from http://www.chkrootkit.org).

"The Sentry tools provide host-level security services for the Unix platform. PortSentry, Logcheck/LogSentry, and HostSentry protect against portscans, automate log file auditing, and detect suspicious login activity on a continuous basis" (from http://sourceforge.net/projects/sentrytools/).

This howto is meant as a practical guide.

Key-Based SSH Logins With PuTTY

Post date: December 10, 2006, 20:12 Category: Security Views: 3972 Comments
Tutorial quote: This guide describes how to generate and use a private/public key pair to log in to a remote system with SSH using PuTTY. PuTTY is an SSH client that is available for Windows and Linux (although it is more common on Windows systems). Using key-based SSH logins, you can disable the normal username/password login procedure which means that only people with a valid private/public key pair can log in. That way, there is no way for brute-force attacks to be successful, so your system is more secure.

The system works by taking mp3 files and feeding them into a transcoder. The transcoder in turn re-encodes the music and passes it to the server. The server receives the stream and when listeners connect, the server splits the stream so that each listener can hear the mp3's.
