Logmonster FAQ - The Network People, Inc.
by camel
Typical Scenario: You have a web server that serves your domain. You write a simple script to restart apache each night and pipe the logs off to your analyzer. It works.
ISP/Hosting Scenario: Each server hosts many domains. You may also have load balanced servers (multiple machines) serving each domain. A tool like this is necessary to:
1. collect all the log files from each server
2. split the logs based on the virtual host(s)
3. discard invalid entries (phishing, referrer spam, etc)
4. sort them into chronological order
5. feed logs into analyzer
6. do something with the raw logs (compress, save to vhost dir, etc)

Set Up Gateway Level Virus Security With ClamAV And SafeSquid Proxy | HowtoForge - Linux Howtos and Tutorials
by camel
In this HowTo, I will explain how you can secure your network from virus and other malware, by installing ClamAV and integrating it with SafeSquid, to scan all in-coming content for virus, and block all infected content at the HTTP Gateway, even before it enters your network.
Virus Security In SafeSquid
SafeSquid has built-in connectivity to various daemon based anti virus software like ClamAV, Sophos, Avast, F-Prot, NOD32 and Kaspersky. It also has a universal ICAP (Internet Content Adaptation Protocol) client that can be used to connect to ICAP based security software like Dr.Web ICAP, Kaspersky Antivirus for Proxy Server, Trend Micro InterScan Web Security and Symantec Scan Engine.
You can even use multiple anti virus software with SafeSquid to simultaneously scan in-coming content. This does not cause any significant latency, since SafeSquid has a multi-threaded architecture.
