 |
|
Hi
I would like to change the LAN additional to IPV6 too. I would like to appeal to the services of Avahi. But i can't ping IPV6 adresses to another host in the LAN. I don't now why. I allready become an IPV6 address.

But i cant't ping another host. When i browse the network with avahi i see all Host with IPV6 and IPV4 togehter. I can't say in the "/etc/avahi/avahi-daemon.conf"
When i do that, i see only IPV6 hosts, but i can't ping with MDNS, so i think IPV6 ist not really present.

I also can't ping only IPV6 IPs.
| Code: | ping6 2001:db8:1:0:5054:ff:feca:90b6/64
unknown host |
What shall i do?

I installed "radvd" on one server in my network, and eth0 on an Ubuntu likes this:
| Code: | eth0 Link encap:Ethernet Hardware Adresse 52:54:00:b8:25:f5
inet Adresse:192.168.1.49 Bcast:192.168.1.255 Maske:255.255.255.0
inet6-Adresse: 2001:db8:1:0:5054:ff:feb8:25f5/64 Gültigkeitsbereich:Global
inet6-Adresse: fe80::5054:ff:feb8:25f5/64 Gültigkeitsbereich:Verbindung
UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1
RX packets:454 errors:0 dropped:0 overruns:0 frame:0
TX packets:147 errors:0 dropped:0 overruns:0 carrier:0
Kollisionen:0 Sendewarteschlangenlänge:1000
RX bytes:59675 (59.6 KB) TX bytes:27368 (27.3 KB) |
So i see two inet6 addresses. And i can ping from a Gentoo the Ubuntu. I also can use the FQDN (form Avahi). But Gentoo becoms no 2th IP6 Address. So i can't ping a Gentoo.
Do I really need radvd? Why do i need 2 IPV6 Addresses?
| Code: | inet6-Adresse: 2001:db8:1:0:5054:ff:feb8:25f5/64 Gültigkeitsbereich:Global
inet6-Adresse: fe80::5054:ff:feb8:25f5/64 Gültigkeitsbereich:Verbindung |
How i configure Gentoo to become a second IP6 Address?

The fe80 address is called a 'link local' address, it is like an RFC1918 address but every device has one.
The other address is globally routed.
You need radvd (+dhcpv6, if you want to hand out dns, ntp, etc) to hand out the globally routable addresses.
I also suggest you learn about ipv6, and read the gentoo ipv6 guide.
Now, this is incorrect: "ping6 2001:db8:1:0:5054:ff:feca:90b6/64 "
Drop the /64, try again. It is like pinging 127.0.0.1/8 - you don't include the mask. |

Thank you for your help, now it works great.  DHCP6 I'll just have to watch.
