MobileMesh is a collection of non-proprietary protocols and software tools which provide media independent mobile ad-hoc networking capability. The protocols have been documented in Internet Drafts and submitted to the IETF's MANET Working Group. These drafts are included in the software distribution. Each MobileMesh protocol is implemented as a separate software tool. A network visualization tool is also provided which displays the topology of the mobile ad-hoc network in real time.
dialin-spammer-block can be used to detect and block dialin clients that try to send send spam over your mailserver. A spammer is detected by watching the mailserver logfile and counting the mails sent by each dialin client. If a client exceeds the limit of mails that may be sent during a certain amount of time, the client will be blocked to relay further mails on the mailserver until the RADIUS server reports that the client has disconnected.
