On our Home LAN, we have several different SuSE machines running. Now, I have run into a problem which I cannot solve myself. One of the computers (a 11.2) just doesn't receive any IPv6 lease from the main router. The router has radvd running and distributes addresses to the other computers just fine. The network card on the box ist a

I have installed a working DNS server on my home network. I have an unique server, devoted to dns, gateway, storage which runs opensuse 11.0 (I known that it is rather old). Two new clients require DHCP. I have installed, using yast, a very simple DHCP server, according to the following config:
option domain-name "XXX.XXX";
option domain-name-servers 192.168.0.1;
option routers 192.168.0.1;
[code]...
(I have tried to add "ddns-update-style none", and to remove the ntp-servers option, since my server is not a time server, without success). Unfortunately, even if the client (a mac running OSX 10.4) receives a right IP and gateway address, it displays neither dns server address nor default domain name. The same mac, on my office network (not managed by me), receives everything.
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?
View 6 Replies View RelatedI 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.

I addes IPv6 address to my interface as
Code:
ifconfig eth0 inet6 add 3fff:ffff:6:5:4:3:2:1
But, when I restart the network service this IPv6 address is gone. How could I make it as a permanent IPv6 address( that should be edited or deleted when I want but not when I only restart the network)to my interface?
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 decided to enable dual stack on my home 11.3 machine and play with IPv6. I use ifup to assign static addresses to eth0. FYI here are some things I found:
1. YaST doesn't seem to support associating IPv6 addresses to interfaces, it complains that the address is invalid. However you can edit /etc/sysconfig/network/ifcfg-eth0 manually and specify it like this:
Code:
LABEL_0='V6'
IPADDR_0='FEC::10.1.1.1/64'
SCOPE_0='site'
and when you restart the networking you will see an additional IPv6 address associated with eth0. Fortunately YaST doesn't mangle the entry when you look at it, but you can't edit it.
2. The SCOPE qualifier is documented in /etc/sysconfig/network/ifcfg.template, but seems to have no effect. Site local addresses in IPv6 are supposed to start with FE[CDEF] according to this:
The TCP/IP Guide - IPv6 Special Addresses: Reserved, Private (Link-Local / Site-Local), Unspecified and Loopback
Once bound, you can connect to services using the IPv6 address just like normal. You have to use ping6 instead of ping though.
I added an AAAA record to my nameserver and that seems to work. Whether the client software tries the IPv6 address varies. It depends on whether the software asks for the AAAA record and uses it. It seems my web browsers don't. I'm not surprised, since few people have IPv6 tails from their ISP. I'm going to look and see if there is some browser setting I have to adjust. I also have to figure out a way of making sure that only LAN destinations use IPv6.
does opensuse 11.2 come with IPv6 enabled by default? where in the gnome gui can i access these settings?
Edit-i went into the gnome network manager applet and i cant find any IPv6 settings for any of my used connections-ethernet, wireless and VPN connections all seem to only IPv4. Can anyone else confirm that opensuse 11.2 uses only IPv4 on its network connections?
I am running suse11.3 32 bit, and have installed squid3.
As far as I can tell it's not been compiled with ipv6 support.
Or have I missed some option in some file somewhere?
To add a new IP address for the network card in the fedora, the only thing I have to do is to copy the file ifcfg-eth0 which is under /etc/sysconfig/network-scripts/ to a new filename called ifcfg-eth0:1 and change the IP address and the DEVICE?
OK, what about other files as following code...
They will be changed automatically if i changed the file under the network-scripts or i have to change them manual?
Am I miss any thing else need to be done?
it's a couple of weeks I can't perform YaST updates from my openSUSE 11.2. The reason is that YaST wants to connect to repositories "only" through IPv6, but my network doesn't support it. I quoted only because I suppose it prefers v6 over v4, but it keeps trying to connect without switching to v4 or returning error.
Even if I disabled IPv6 from YaST/Networking/Network Settings, I still have a local scope address. I connect to Wifi using KNetworkManager. The TCP/IP stack should know that if an interface has a local scope v6 address and a global v4 address, it's a bad idea to keep trying with v6. Italian mirror, garr.it, of openSUSE repository both has v4 and v6 addresses. If I try to ping opensuse.mirror.garr.it I ping v4, but if I try to telnet that host on port 80 it tries to connect to v6. Same if I try to connect with Firefox.
How to tell Linux that I don't have IPv6? I'm connecting from University of Naples wireless network. While unina has IPv6 via GARR's Teredo tunnel (2001:760::/32 as I remember), it doesn't reach students' network because DHCP server doesn't release IPv6, nor Zeroconf obtains one. I just would like to use classic IPv4 until, at least for now.
Is it possible to setup samba to work over IPv6?

I can ping anything within the same subnet but anything outside of that it gives me host unreachable. I believe that it is not routing for some reason, but I am not sure why.

I'm having a little problem here. That, or I'm missing the obvious staring me in the face. I have this file server, called toad. I nuked it's system disk, reorganising the partitions and upgrading to openSUSE 11.3 x64. I installed vsftd with "Yast FTP server", and the config looks OK. I even compared it with that of another machine. But when I try to connect, this is what I get:
user@mainmachine:~> ftp
ftp> open toad
Connected to toad.geuens.org.
500 OOPS: could not bind listening IPv6 socket
I'm prettige sure IPv6 is deactivated. The firewall is disabled on both machines. I've looked this over again and again. Can't find it. It's not the connecting machine, I've tried from another.
IPV6 gets more and more interesting. YAST is failing to connect to the repositories. I have disabled ipv6 in several ways but none of them work or YAST (also Konqueror) seems to do it's own thing. I have managed to get Firefox to work see my "slow internet seems to be down to dns post" made earlier today. So as a check on the YAST problem I loaded each of the repository addresses into Firefox and lo they all connect without any problem at all. So it seems that the YAST problem is down to IPV6
In order to disable ipv6 I initially added ipv6.disable=1 to the end of all of the bootloader APPENDS. More recently following up further info on here I added a couple of lines to
/etc/modprobe.d/99-local.conf. These were:
alias net-pf-10 off
alias ipv6 off
This doesn't work either.
Maybe of use to others - It seems it's possible to see if IPV6 is active by typing the following into the command line:
ip a | grep inet6
I'm told if it is active lines will be output? So just what do I do to disable it in YAST and I hope in Konqueror too? It's beginning to look like it is enabled or disabled at the app level according to the Firefox fix.
I've had a hell of a time with this and now all but YAST2 are ok. Going back some time to 10.0 this could be used to disable it very completely.
open terminal and run
echo "alias net-pf-10 off" >> /etc/modprobe.conf
echo "alias ipv6 off" >> /etc/modprobe.conf
restart computer. Has anyone used this on more recent issues even 11.4 and are there any repercussions?I assume that the inverse will but it back on ie off's just become on's? I will be using cups when I install my printer which is one concern and I am not at all sure that modprobe will do anything anymore?
I also recollect that there is a command to cause the kernel to effectively reboot which would save restarting. Can't remember what it is. Maybe some one can refresh my memory.
I have a server with 2 network cards. eth0 is used for all traffic and everything is working fine on this side. Eth1 is used for traffic to and from 1 ip address.
Lets say the ip address of eth1 is 123.123.123.10 and its gateway is 123.123.123.1. I need to pass all traffic to 123.123.123.20 through eth1. What command would i use?

I 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:

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 second network card in my ubuntu desktop that I have sharing my internet connection with a wireless router. I have set the router to a static ip address within the network cards range. But, every time I restart the computer, the network card uses a different ip address. One time it will be 10.42.43.1, the next time it will be 10.42.46.1, ect. This makes me have to hard reset my router every time it does this. How can I set the network card to use the same ip address all the time?
