Luigi, it will be really brilliant if you would be kind to show more examples of use netmap with pipes, netgraph modules (for example, ng_netflow) and so on, because many of network engineers use FreeBSD without as strong programming skills as you have. At least I'm the one of they. ;) BTW, Ermal, are the any chances to see you patches for work dummynet in the PF? 10.02.2014 21:28, Luigi Rizzo пишет: > On Mon, Feb 10, 2014 at 12:44 AM, Ermal Luçi <eri@freebsd.org> wrote: > >> Hello Luigi, >> >> On Mon, Feb 10, 2014 at 2:14 AM, Luigi Rizzo <rizzo@iet.unipi.it> wrote: >> >>> On Sun, Feb 9, 2014 at 4:21 PM, Raimundo Santos <raitech@gmail.com> >>> wrote: >>> >>>> Hello list! >>>> >>>> I am willing to test an idea: modularize network functions using vnet >>>> jails.
