Linux Socket Monitor

Current Release:

Description:
LSM is a network socket monitor; it is designed to track changes to Network sockets and Unix domain sockets, effectively a port monitor. It does this by a rather simple differential based comparison of current and new server sockets (Server Ports). A simple and configurable alerting system sends alerts whenever new ports activate. LSM will ignore services that are currently holding sockets open, events are only applicable when a ‘new’ socket (port) is created.

Funding:
Funding for the continued development and research into this and other projects, is solely dependent on public contributions and donations. If this is your first time using this software we ask that you evaluate it and consider a small donation; for those who frequent and are continued users of this and other projects we also ask that you make an occasional small donation to help ensure the future of our public projects.

    another error report, cronjob (affects bfd, too).

    Oct 30 21:14:01 host /usr/sbin/cron[1585]: (*system*bfd) ERROR (Syntax error, this crontab file will be ignored)

    The version of cron shipped with debian and ubuntu seems to have problems with the assignment of the SHELL and MAILTO variables.

    SHELL=/bin/bash -> does not work
    SHELL=”/bin/sh” -> works

    Thanks for you efforts!

    Any ideas? System is IPv6 enabled. This is the output of "netstat -npl":

    Jason:

    Hi,
    Great project, thanks!
    Quick question. In the conf the USER setting. Is this meant for a user or an email address?

    It can be a local system account, or an email address. A local system account requires the proper mail services installed locally. I would recommend you set this to an email address.
