How secure are apps that using RPC portmapping?
In general the golden rule for the security consists in activating fewer services possible and only when necessary. Perhaps I will try an application (this is a file manager) that seems to apply to use this service, such dangers arise in safety? |

Restrict usage of open ports by enabling OpenBSD's packet filter, PF.
Read the PF User's Guide and related man pages. |

I like play on firewall, indeed I have already enabling OpenBSD's packet filter.
![]() In essence, to reduce the problems a good solution might be to identify the ports used by the service and then set them for exclusive use at a local? |

For more detailed information, excluding any outgoing/incoming UDP/TCP connections.
$ fstat | grep internet | grep -v -e '>' -e '<' It could probably be done in a cleaner fashion, but at least with this, you can determine some additional information about the process that opened the port. Last edited by BSDfan666; 9th June 2008 at 09:58 PM. |
