Direct kvm interface was removed from head a year ago. What you can do is recompiling netstat binary from 9 with NewTree variable defined to 1 and see if this helps. Output will look a bit different, but you'll be able to see routing tables from jail. https://svnweb.freebsd.org/base/stable/9/usr.bin/netstat/route.c?revision=242025&view=markup#l122 Another option is merging r261207 and r263335. > > Thanks! > > --Chris > > -- > > _______________________________________________ > freebsd-current@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
