IPv6 pre vsetky počítače v lokálnej sieti
Přečteno: 1249×
Odpovědět | Admin
Dobry vecer Mam problem rozbehat podsietovanie v ubuntu 9.10. Tunel mam vytvoreny u SixXS a mam aj prideleny prefix. Robil som to podla navodu: IPv6 pre vsetky počítače v lokálnej sieti Mam asi nieco zle nastavene alebo neviem. Neda sa mi to rozbehat. Potrebujem to rozbehat na ntb, ktory funguje cez Wifi a bude sa spravat ako server (koniec tunela, router pre ostatne pocitace v sieti

Subnet Prefix : 2001:15c0:6717::/48

Tunnel Endpoint : 2001:15c0:65ff:395::2

vypis nastaveni:

/etc/radvd.conf

interface eth0 {
        AdvSendAdvert on;
        AdvHomeAgentFlag off;
        MinRtrAdvInterval 30;
        MaxRtrAdvInterval 100;
        prefix 2001:15c0:6717::/48 {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};
/etc/sysctl.conf 
# Uncomment the next line to enable packet forwarding for IPv6
net.ipv6.conf.all.forwarding=1
/etc/network/interfaces 
auto lo
iface lo inet loopback

iface eth0 inet6 static
        address 2001:15c0:6717:1::1
        netmask 48
        mtu 1280
Pri spusteny /etc/init.d/radvd start 
Starting radvd: 
* IPv6 forwarding seems to be disabled.
* See /usr/share/doc/radvd/README.Debian
* radvd will *not* be started.
Prosim ak mi viete pomoct tak pome nato :) Dakujem

Tak si predne over jestli ti chodi tunel, vytvori si zkusebni statickou IP v LAN, nastav routovani a over jestli to funguje staticky. Potom se muzes pustit do dynamickeho pridelovani.

Co vypíše cat /proc/sys/net/ipv6/conf/all/forwarding ?

Spustil jsi po nastavení sysctl? sysctl -p

toto je vypis:

Nejdrive se podivej do ubuntacke konfigurace site, jestli nemas ipv6 zakazane nejakym zpusobem, pokud ne, tak zkus nejdrive:

sysctl -w net.ipv6.conf.all.forwarding=1

Pak znova spustit radvd, dokud bude psat tu chybu, nebude to fungovat pro ostatni PC.

spustil som a znova som spustil radvd a napisalo. 
root@ekinek:~# sudo /etc/init.d/radvd start
Starting radvd: radvd.
Tak a teraz by mi to malo pridelovat adresy automaticky ? chcem pripojit dva desktop PC na ktorych je WinXP......

staci do cmd zadat lent toto ? a potom by sa to ako malo chovat ? autokonfiguracia ? 
ipv6 install
netsh interface ipv6 set privacy disabled

no tak spustil som aplikaciu radvd presla bez problemov.... na hostovi som spustil radvdump informacie som dostaval ... pridelilo mi aj ipv6 globalnu adresu, ale vobec mi nejde z hosta svet ipv6 , neda sa pingnut ipv6.google.com .... tunel je funkcny.

Tak se podívej do routovací tabulky, zkus si pingnout na bránu atd.

neviem ako este nastavit konkretne tuto vec : accept_ra . Treba to aj vo win aj v ubuntu ? 
a všechny počítače ve vaší lokální síti s povoleným IPv6 a povolený accept_ra (výchozí stav) mají přidělenu IPv6 globální(veřejnou) adresu.

Davat na ethernetovy segment /48 neni dobry napad. Zmen to na /64 jak v radvd.conf tak v network/interfaces

Ze ti negunguje ipv6.google.com muze mit nekolik pricin. Jde to z toho routeru? Nebo to nejde ani z routeru ani z klienta? Co rika "ip -6 route"? Nemas nahodou zapnuty firewall? Co rika "ip6tables -L"? Zkus se pomoci tcpdump (nebo wireshark) podivat jestli z klienta na router chodi nejaky ipv6 provoz a jestli neco jde ven tim tunelem (napr 'tcpdump -i eth0 -n ip6' a 'tcpdump -i sixxs -n' [kde misto sixxs napis jmeno interface toho tunelu]).

Pomenil som segmenty na /64 Z routera to vonku ide , pridelil aj ipv6 adresu klintovi na ktorom bezi ubuntu. Ked na nom spustim radvdump tak prichadzaju oznamenia. Nejde mi to vonka s klienta.

To jsou dva ruzne prikazy ;-)

Na routeru v jednom okne spust:
tcpdump -i eth0 -n -s0 ip6
a ve druhem okne spust:
tcpdump -i sixxs -n -s0
(misto sixxs tam napis jmeno tuneloveho interface, zjisti se treba z "ip -6 addr show")

Pak z klienta zkus otevrit ipv6.google.com a posli sem vystupy obou tcpdumpu.

Pak taky na routeru spust:
ip6tables -L
ip -6 route
sysctl net.ipv6.conf.all.forwarding
a dej vedet co pisou.

Robi mi to daku neplechu , ked prepisem config

sudo nano /etc/network/interfaces 
iface eth0 inet6 static
        address 2001:15c0:6717:1::1
        netmask 64
        mtu 1280
tak mi po restarte PC alebo network interface vypne eht0 ... da ho do stavu ifupdown eth0 a prepne to na wifi .. (route je ntb). nepomohlo ani

sudo ifconfig eth0 up

pomoze len to ze cely config vymazem a potom nabehne na Auto eth0 , ale ja ho potrebujem mat nastaveny na podsietovanie nie ? Asi mi treba toto vyriesit lebo prikaz

tcpdump -i eth0 -n -s0 ip6

mi nechce zobrat

ip -6 addr show

auto eth0 tam musis mit, jinak se ti AFAIK eth0 automaticky nenahodi. Tohle je staticky IPv6 config z jednoho meho debianiho serveru:

auto eth0
iface eth0 inet static
        address a.b.c.d
        netmask 255.255.255.224
        network a.b.c.0
        broadcast a.b.c.31

iface eth0 inet6 static
        address 2001:e20:2000:xxx::1
        netmask 64

Po rebootu bys mel mit obe adresy nastavene:

~ # ip a show dev eth0
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 00:e0:ab:cd:91:35 brd ff:ff:ff:ff:ff:ff
    inet a.b.c.d/27 brd a.b.c.31 scope global eth0

    inet6 fe80::2e0:abff:fecd:9135/64 scope link
       valid_lft forever preferred_lft forever

V tom tcpdumpu pouzij 'sixxs' tak jak jsem psal a vsechno to sem posli.

Hned ako vyriesim ten problem s network interface eth0 ifupdown eth0 tak vypisem tie config.

ked mam v nom nastavene: 
auto lo
iface lo inet loopback

iface eth0 inet6 static
        address 2001:15c0:6717:1::1
        netmask 68
        mtu 1280
Tak mi to prepne na ifupdown eth0, ked vymazem tu cast od iface eth0 inet6 static ... tak sa to prepne na Auto eth0 ... patram, ale nemozem nic najst.

Zajimave. Ja Debian moc nepouzivam takze cim to muze byt ze ti nechce nakonfigurovat sitovku to bohuzel nevim. Mozna zkus zrusit ten radek s "mtu 1280" - konec koncu nizsi MTU ma ten tunnel, eth ma MTU 1500, takze je zbytecny mu nastavovat nizsi MTU.

Taky muzes zkusit tu adresu nastavit rucne:

ip a add 2001:15c0:6717:1::1/64 dev eth0

Pak muzes zkusit ty prikazy co jsem ti driv psal.

Sorry ale tenhel vypis neni moc k nicemu. Takze znova:

  1. Spust na routeru dva tcpdumpy - jeden na eth0 a jeden na sixxs rozhrani. A nech je pustene.
  2. Na klientu zkus otevrit ipv6.google.com a pockej az dostanes nejakou chybu.
  3. Ukonci oba tcpdumpy na routeru a posli sem oba vypisy.
eth0 mam v stave odpojenom ifupdown

Nevim co tim myslis. Co je ifupdown? Interface je bud up nebo down, ifupdown neznam. Nemohl bys alespon docasne nahodit ten interface rucne pomoci /sbin/ip?

To vypada ze odpovedi z ipv6.google.com (2a00:1450:8001::63) router nepusti zpatky na eth0. Ale jelikoz se skrz dostal ping request smerem ke Googlu tak ti routovani i packet forwarding nejspis funguje. Nemas nahodou spusteny IPv6 firewall? Co na routeru rika "ip6tables -L"? Pokud tam jsou nejaka pravidla nastavena tak je pro zacatek zkus vymazat pomoci "ip6tables -F" a uvidis jestli to zacne pingat.

Uz se v tom trochu ztracim. Takze klient je pripojen kabelem na eth0? Co kdybys na wlan na chvili uplne zapomnel a rucne nastavil eth0? Neco jako:

ip link set wlan0 down
ip link set eth0 down
ip link set eth0 up
ip a add 2001:15c0:6717:1::1/64 dev eth0
ip a add 192.168.1.103/24 brd + dev eth0

a ted zkus jestli to pinga a jestli ne posli sem vypis "ip -6 r" z routeru.

No dobre, ted uz mas nastavenou IPv6 adresu na eth0 (a dokonce na ni muzu pingnout, coz je dobre znameni). Jak vypada tvuj radvd.conf na tom routeru? Melo by tam byt neco jako:

interface eth0
{
        AdvSendAdvert on;
        MinRtrAdvInterval 30;
        MaxRtrAdvInterval 90;
        AdvDefaultPreference high;
        prefix 2001:15c0:6717:1::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr off;

                AdvValidLifetime 900;
                AdvPreferredLifetime 300;
        };
};

Hlavne zkontroluj jestli ten prefix je spravne. Pak restartuj radvd a pockej az klient dostane adresu z rozsahu 2001:15c0:6717:1::/64 ("ip addr show" na klientovi ti rekne jake adresy tam jsou). Pak uz by to melo chodit.

V predchozich vypisech figuruje adresa 2001:15c0:6717:ffff:211:d8ff:fe12:b60d - ta na klientovi byt nema protoze ...:ffff:... tam neni routovane. Radsi ji smaz: "ip a del 2001:15c0:6717:ffff:211:d8ff:fe12:b60d dev eth0" na klientovi.

Ked mam doplneni NM config o inet6 tak mi vyhodi pridelovanie z routra (linksys) IPv4 a prepne ma automaticky na wifi a eth0 da do stavu ifupdown eth0 , ale ako vidno tak mi prideli ipv6 na eth0

Dale si overis routtovaci tabulku na routeru:

A pridas default routu do sixx pokud nemas:

ip -6 route add default via 2001:15c0:65ff:395::2

A zapnes forwardovani:

Na klientu zadas take default gw pokud nemas:
