Installing iRedMail And Mailman On Debian Squeeze

I'm a big fan of iRedMail, which is basically a packaged version of Postfix and the other bits that make Postfix cool, like Spamassassin, greylisting and an LDAP or MySql back-end. One thing I wanted with iRedMail is Mailman, my favourite mailing list server. Integrating the two can be a mission though, so here's some instruction to save you from quite a bit of pain.

Configuring CAS On Ubuntu For Two-Factor Authentication With WiKID

Single sign-on is a great technology. Requiring users to login to multiple applications is huge hassle, encourages password reuse and simple passwords. Security needs to focus on usability. If you can make a user's life better while increasing security, everybody wins. In this how-to we will set up the open-source CAS SSO product with the WiKID Strong Authentication Server for two-factor authentication for sessions and mutual https authentication for host authentication. Obviously using two-factor authentication for the login increases security because the user must have the factors to get access, in this case, knowledge of the PIN and possession of the private key embedded in the token. The CAS server is running on Ubuntu 11.04 Server and is using Radius to talk to the WiKID Strong Authentication Server Enterprise Edition.

SQUID Proxy On RHEL5/CentOS - Everything That You Should Know About [Part 1]

The main feature or duty of a proxy server could be a gateway that receives HTTP requests from clients and forwards the request to the destination and relays the answer back to the requestor.

It also has some excellent features for doing something else such as web access controlling, bandwidth controlling, restriction policies, and content caching and filtering. Actually people install SQUID to pursuit 2 goals: first reduce the bandwidth charges by content caching and second for restricting access to particular contents. The following guide explains advantages of using Squid and will show you how to install, configure, control, and maintain the Squid Proxy Server on RHEL5 and CentOS Linux.
