zdravim predpokladejte nastadujici stroje L(linux), F(freebsd) pokousel jsem se udelat ze stroje L L> ssh F -l root -w 9:9
co se mi povedlo a na obou strojich se objevil tun9 interface dale jsem na obou strojich nastavil ipv6 na tun9 L> ifconfig tun9 up; ip addr add 2002:2::2/48 dev tun9 F> ifconfig tun9 up; ifconfig tun9 inet6 2002:2::1/48 dale jsem si zkusil L> ping6 2002:2::1 F> ping6 2002:2::2 ani jedno neslo, tudiz jsem nechal pingat L a na F jsem si pustil F> tcpdump -i tun9 tcpdump: WARNING: tun9: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun9, link-type NULL (BSD loopback), capture size 96 bytes 18:20:39.184400 IP6 , wrong link-layer encapsulationbad-hlen 0 18:20:40.192896 IP6 , wrong link-layer encapsulationbad-hlen 0 ... pokud udelam ping6 z F a dumpuju na L F> ping6 L L> tcpdump -i tun9 tcpdump: WARNING: tun9: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun9, link-type RAW (Raw IP), capture size 65535 bytes 18:22:57.434605 IP6 2002:2::1 > 2002:2::2: ICMP6, echo request, seq 5, length 16 18:22:57.434654 IP6 2002:2::2 > 2002:2::1: ICMP6, echo reply, seq 5, length 16 18:22:57.444464 IP6 2002:2::1 > 2002:2::2: ICMP6, neighbor solicitation, who has 2002:2::2, length 24 18:22:57.444512 IP6 2002:2::2 > 2002:2::1: ICMP6, neighbor advertisement, tgt is 2002:2::2, length 24 ... na F ale ping nehlasi, ze by neco prislo a tcpdump mi ukazuje F> tcpdump -i tun9 tcpdump: WARNING: tun9: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun9, link-type NULL (BSD loopback), capture size 96 bytes 18:24:21.436478 IP6 2002:2::1 > 2002:2::2: ICMP6, echo request, seq 89, length 16 18:24:21.439201 IP6 , wrong link-layer encapsulationbad-hlen 0 18:24:22.436464 IP6 2002:2::1 > 2002:2::2: ICMP6, echo request, seq 90, length 16 18:24:22.439817 IP6 , wrong link-layer encapsulationbad-hlen 0 kdepak by mohl byt problem? :) diky fous -- FreeBSD mailing list (users-l@freebsd.cz) http://www.freebsd.cz/listserv/listinfo/users-l
