That's the reply I was sort of expecting, and the reason I asked. If this is meant to be used for network sockets, then a mechanism in FreeBSD that is similar to streams: it is called "NETGRAPH". There are various 'node types' in FreeBSD already, which support various sorts of packet processing, filtering, rewriting, etc. The manpages of all the ng_xxxx(4) nodes are quite informational, and you can find a few good references for Netgraph in Julian Elischer's personal web space at FreeBSD.org: http://people.freebsd.org/~julian/ There are currently more than 50 different Netgraph node types in FreeBSD 7.0-CURRENT, providig packet functions such diverse as Berkeley packet filtering, a generic tunneling interface, packet firewalling, NAT functions, kernel mbuf tagging, or VLAN tagging, and so on. See all the ng_xxxx manpages with: % man -k ng_ and the webpage of Julian mentioned above. Hopefully, you can find something that can help you get started. If an existing Netgraph node doesn't match 100% the functionality you want to do, you can always copy an existing node sources and modify them to create a node type of your own :-) HTH, Giorgos _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
