- PPTP Server
The PPTP VPN app is a server-side implementation of the PPTP protocol. It is primarily used for client-server VPN tunnels (as opposed to server-server). The main advantages of this protocol are ease of use and low cost as the client-side software is built into all Windows OS, in addition to free clients for Mac and Linux distributions. Along with the advantages, it should be stated that the PPTP protocol is the weakest in security of all the main VPN protocols (IPSec, OpenVPN, L2P). The protocol splits traffic into control and data streams, and passes all control packets across the network without any encryption. The result is that PPTP is vulnerable to attack or hijacking and known breeches in security using this protocol have been demonstrated.
- Resource Report
The Resource Report app includes information on load, memory usage and running processes.
- Mail Greylisting
For servers configured to provide on-premise mail service, the greylisting app can dramatically reduce the amount of spam reaching user's mailboxes. The mail transfer agent (MTA) will temporarily reject any attempt to deliver mail to the server from an unknown source. MTA's from legitimate sources will automatically queue the mail and attempt to deliver again while spammers will typically move on, not bothering to resend the message after a short delay. If your users are wasting time sifting through their inboxes as a result of spam, this app can significantly improve the situation. One disadvantage of implementing greylisting is the delay it invokes on receiving mail from new users - essentially destroying the near-instantaneous communication that people have come to expect.
- Mail Antispam
An open-source antispam scanner for the SMTP Mail Server app. This app will scan mail during messaging handling and perform functions defined by rules configured by the administrator. For commercial applications, ClearCenter offers additional spam rules that are continually updated as a service.
