Increasing the security of PPTP by adding two-factor authentication to poptop

Security Issues and Poptop

PPTP does not have the best history in terms of security. The original Microsoft implementation for PPTP faired very poorly. MS-CHAPV2 solved these weaknesses - for wired networks. Unfortunately, back in 2004, Joshua Wright released a version of ASLEAP capable of brute-force attacking PPTP passwords in a wireless environment. As a systems administrator for the VPN, you can't tell if a user is connecting via some public WiFi service where someone might be running a tool like ASLEAP. Yet, the presense of PPTP client software on Windows machines makes using PPTP very tempting. The best answer to this problem is to utilize two-factor authentication. If a one-time passcode is brute-forced, it won't matter as it can't be used again.

Server Monitoring With munin And monit On Mandriva 2008.0

Server Monitoring With munin And monit On Mandriva 2008.0

In this article I will describe how you can monitor your Mandriva 2008.0 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Connecting GPRS From Ubuntu Gutsy

Connecting GPRS From Ubuntu Gutsy

Connecting to GPRS using a Nokia Phone is not too tough in Ubuntu Gutsy. This is because the default udev rules does install the required drivers and map most of the Nokia devices to /dev/ttyACM0. But it can become tough if you need to retain the resolv.conf or making the pppd to add a default route to the connected device. We will see how it was done properly in the Saturn Labs.
