Pentru activarea ipv6 pe o instalare Debian implicita se folosesc urmatoarele comenzi din shell:
ip link set eth0 down ip link set eth0 up echo 1 > /proc/sys/net/ipv6/conf/eth0/accept_ra dhclient eth0
Pentru a testa: lftp ftpv6.lug.ro sau se acceseaza din browser un site web care foloseste ipv6 (de ex. http://ipv6.google.com, http://www.ripe.net, http://www.whatismyipv6.net/).
Metoda a fost testata la Atelierul RLUG din ianuarie 2011.
RDS experiment
Incepand cu 10 octombrie 2011, RDS ofera ca serviciu experimental clientilor home-user cate o clasa /64 peste PPPoE. Pana la un tutorial complet, cativa pasi la care trebuie avut grija:
- In primul rand, activat serviciul de IPv6 din interfata web Digicare ( Servicii -> Internet -> IPv6 Test )
- Se configureaza pppd:
- rp-pppoe cu plugin rp-pppoe.so: se adauga la parametrii pppd-ului rp_pppoe_service ipv6test +ipv6
- rp-pppoe standard: se adauga linia "+ipv6" in /etc/ppp/options si "ipv6test" la "SERVICENAME" in /etc/ppp/pppoe.conf
- Ubuntu: daca pppoe nu e deja setat, se ruleaza pppoeconf; se adauga liniile "rp_pppoe_service ipv6test" si "+ipv6" in /etc/ppp/peers/dsl-provider si se restarteaza pppd ruland poff si apoi pon dsl-provider
- se instaleaza un client de DHCPv6 care stie Prefix Delegation (wide-dhcpv6-client de la ISC stie).
- daca e nevoie de retea interna, trebuie setat dhcp6c.conf sa faca disable la reteaua 'loopback' si lasata doar cea de lan, daca nu, trebuie doar cea loopback
- la reteaua care ramane se seteaza sla_len = 0
- pentru advertisingul noii clase in reteaua interna, e necesara instalarea radvd (probabil configul implicit functioneaza)
- ddclient are nevoie de un patch: http://bit.ly/oc2JKq si de optiunea "usev6=if, if=ppp0"
Setari OpenWRT
Backfire 10.03.1
- /etc/config/network
...
config 'interface' 'wan'
option 'ifname' 'eth1'
option 'proto' 'pppoe'
option 'username' '.....'
option 'password' '.....'
option 'ipv6' '1'
option 'service' 'ipv6test'
- /etc/config/dhcp6c
config 'dhcp6c' 'basic'
option 'enabled' '1' # 1 = enabled; 0 = disabled
option 'interface' 'wan' # This is the interface the DHCPv6 client will run on
option 'dns' 'dnsmasq' # Which DNS server you run (only dnsmasq currently supported)
option 'debug' '0' # 1 = enable debugging; 0 = disable debugging
# Send options (1 = send; 0 = do not send)
option 'pd' '1' # Prefix Delegation
option 'na' '0' # Non-Temporary Address
option 'rapid_commit' '1' # Rapid Commit
# Request options (1 = request; 0 = do not request)
option 'domain_name_servers' '1'
...
# Define one or more interfaces on which prefixes should be assigned
config 'interface' 'loopback'
option 'enabled' '0' # 1 = enabled; 0 = disabled
option 'sla_id' '0' # Site level aggregator identifier specified in decimal (subnet)
option 'sla_len' '0' # Site level aggregator length (64 - size of prefix being delegated)
# e.g. /60 from ISP -> 64 - 60 = 4
config 'interface' 'lan'
option 'enabled' '1'
option 'sla_id' '1'
option 'sla_len' '0'
- /etc/config/radvd
config interface
option interface 'lan'
option AdvSendAdvert 1
option AdvManagedFlag 0
option AdvOtherConfigFlag 0
list client ''
option AdvLinkMTU 1452
option ignore 0
config prefix
option interface 'lan'
# If not specified, a non-link-local prefix of the interface is used
list prefix ''
option AdvOnLink 1
option AdvAutonomous 1
option AdvRouterAddr 0
option ignore 0
- /etc/config/firewall pentru Backfire 10.03.1-RC6 și anterioare:
(altfel dupa ifdown wan/ifup wan, dhcp6c nu mai primeste reply)
config 'rule'
option 'target' 'ACCEPT'
option 'src' 'wan'
option 'proto' 'udp'
option 'src_port' '547'
option 'dest_port' '546'
option 'family' 'ipv6'
- Iar pe calculatoarele din LAN:
net.ipv6.conf.all.accept_ra = 1 net.ipv6.conf.default.accept_ra = 1 net.ipv6.conf.eth0.use_tempaddr=2 net.ipv6.conf.default.use_tempaddr=2
Pentru imagini testate pe RCS-RDS dual stack cu routere compatibile OpenWRT - http://www.ip6.ro/firmware - exista si rootfs unde se pot inspecta fisierele de configurare.
