I am trying to get the MX record using dig command supplying IPv6 address of host. but i am getting connection timed out .
while with IPv4 address and host-name its working fine.
I have been struggling to get FC15 to act as an IPv6 router for a while now, am sure I am missing something trivial.. The idea is that I have a ppp / adsl connection (this works fine), use the wireless card on my pc with hostapd and dhcpd to provide connections to other pcs (works fine), and radvd to delegate ipv6 addresses.
The issue seem to be that as soon as I turn on ipv6 forwarding (net.ipv6.conf.all.forwarding =1), the ppp connection no longer gets an IPv6 address. This means the router cannot ping any ipv6 address outside my network.
If I disable ipv6 routing, my router gets an IPv6 address on its ppp connection, and can ping things such as ipv6.google.com just fine, however (of course) no packets are forwarded from my network and radvd complains that forwarding is disabled.
I use DNS on my server as a chasing DNS so its not fully configured. I seem to be having trouble with IPV6 addresses. I'm guessing this is linked to the 6to4 tunnel I have set up to my windows box, but I'm not really sure.
Code:
May 21 18:00:16 hyrule named[1148]: error (network unreachable) resolving 'D.ROOT-SERVERS.NET/AAAA/IN': 2001:dc3::35#53
May 21 18:00:16 hyrule named[1148]: error (network unreachable) resolving 'B.ROOT-SERVERS.NET/AAAA/IN': 2001:500:1::803f:235#53

I've registered a top-level domain site.com pointing to my IPv6 address (6to4 tunnel). Everything looks ok, dig command, nslookup command shows requested output, but: I'm not able to connect to mail.site.som on 110 port. I still get an error messaged, that connection has been refused. I've populated the ip6tables with commands to open desired port but with no success. I'm listening on 25, am able to connect to this port, but not to 110.
Command netstat -an | grep "LISTEN " shows that I'm not listening on 110 port, although I'm just added this port to the firewall exceptions. Telnet to ::1/tunneled IPv6 address is successful. Postfix installed, configured properly, ping6 working. Everytime I try to send email from external domain, I'm advised that the mail domain is not pointing to A record.
I added an init script numbered just before bind9 starts, which needs to see the ipv6 link-local address on eth0. Sometimes this address is not configured, yet. In all cases it eventually is configured.
I am unable to find any script that is configuring the ipv6 link-local address (which is in part based on the MAC address). Does anyone know if there is some script or program that is supposed to be doing this, or is it an internal kernel function?
One workaround I am considering is making this init script go into a loop around sleep 1 to keep checking for the ipv6 address. But I'm concerned this might cause some problems. Any suggestions? I don't want to let it move on to start bind9 until the configuration this script does (more ipv6 addresses) is done.
This is on Ubuntu 9.10 server (for which there is not a prefix choice).
I have installed Fedora 11 and I have set it up as a web server with Apache. I have a domain name from GoDaddy that I own and I have set it to my web server. I am able to type the address into a browser on a computer outside of my network and it will pull up the web pages on the server. the problem that I am having is that after I type the URL, it gets replaced with the IP address. [URL] I know that I need a nameserver to resolve the IP address but I can not figure out how to do it. I have tried to use Bind but I can never seem to get it to work.

here is the only part in the httpd.conf file that seems to have anything to do with this:

View 2 Replies View RelatedI have a problem with my ipv6 connection: although I can't get ipv6 address with DHCP, I can't use ipv6 network. I tried [URL], and the tortoise is static. I want to fix it out , so I use 'ifconfig' to see my network configuration:
eth0 Link encap:Ethernet HWaddr 00:50:8d:ef:dd:06
inet addr:210.77.9.102 Bcast:210.77.11.255 Mask:255.255.252.0

Some people told me that the fisrt ipv6 address was wrong and unsuitable for ipv6 connecting. I tried /ect/init.d/networking restart but it didn't work. How can I use the second address as my ipv6 address and fix the problem out ? Now it seems there is not problem with the ip adress but the route. After watching some video, I suddenly could use ipv6. I did 'ifconfig' again and nothing was different. However, the result from the command 'ip -f inet6 route' changed: the last default route was gone and there was only one default route.
I have a networking problem with my computer. Under Windows, the computer can get both v4 and v6 address via DHCP. However, the same computer can only get v4 address under Ubuntu. Does anybody know how to solve this problem?

I want to add an ipv6 address in linux.
i am going to use the following command.
# /sbin/ifconfig <interface> inet6 add <ipv6address>/<prefixlength>
Can anyone explain how this command will works?
Is that prefix length value is fixed to 64 or is it vary?if so,can you explain how it could be?
When I do ifconfig than IPv6 address is appearing on an interface. However when I run the system-config-network and select to edit same interface than it shows the normal ip4 192.168.1.x address. Why is it like that? ipv4 at one place and ipv6 at other?

I have an Ubuntu 10.04 server/router with IPv6 internet connectivity (I have an internet routable /64 subnet). Since I have this abundance of IPv6 addresses I wanted to try and assign v6 addresses to specific users on the local system. I've been looking at ip6tables with packet mangling but I don't seem to be able to find out how to do this or if this is even possible.
Current configuration: eth0: Local network, has the /64 IPv6 public range active and the IPv4 LAN range. tun0: 6in4 tunnel with a ISP assigned public v6 address. eth1: Standard IPv4 internet connection.
All users on my system use the v6 address configured on tun0. I want to force them to use the /64 range which is configured on eth0. If I can force users to use a specific v6 address, I'll configure more then one v6 address on this interface based on the users userID on the system.
I've two WLAN AP's with both a different IPv6 subnet. When I change from one AP to the other, my IPv6 Global address stays valid and so is the default IPv6 gateway. After a while I get another Global address from the second AP's subnet and another default IPv6 gateway for the second subnet. Both have the same metric. IPv6 connectivity is broken now. When I disable wireless on the laptop and reenable it, it flushes all IP addresses and receives new ones and connectivity is restored. Does anyone know if this is normal behaviour or should it normaly flush all the addresses when changing network? It's a bit silly to have to disable/enable wireless all the time..

I can reach other hosts by means of their global addresses by either the IP address or hostname (that has the global address). What I want to (also) do is have a hostname that references the IPv6 link local IP address (an AAAA record in DNS, or just the fe80::<whatever> address in /etc/hosts) and use that host name in commands to access that host. The problem is, an interface ID is needed when making such a reference.
It sure looks like the programs just pass the host name string on to the resolver library, which does not understand the significance of the '%' even though it could find and see that the name preceding the '%' is consistent with that being an IPv6 link local address (e.g. the logic could have been "split at first % and see if preceeding name is found as a link local address and accept that if so, or ignore the split otherwise" ... but it isn't). Is there a different syntax for this ... or was it overlooked in the design of programming around IPv6?I want to be able to address a host by its link local address, while still using a mnemonic instead of having to type the IPv6 address.
My ISP offers the service of native IPv6. So my ADSL router provides me with a local and global IPv6 address. However after a reboot it takes minutes to finally see the global address when using "ifconfog eth0". During that time I can't do a ping6 to an external server, which seems logical. So I waited several minutes, but no global address. After that I started a KDE session, went back to the console(<Ctrl>+<Alt>+F1) and now the global address was there. Is this normal behavior or should I file bug report?
