Ubuntu Networking :: IPv6 - Automatic Configuration Not Working?
Apr 19, 2011
I just purchased a router that supports IPv6 and configured my eth0 to use IPv6. I have tried automatic and automatic, address only with no results. My Windows 7 and OS X 10.6 boxes both work w/o issue of need to change settings. I have done a bit of Google searching, but not found much in the way of useful advice. Can someone point me to a good article or let me know that the product is broken at this point.

I have a server application that uses loopback addresses to open servers on linux machine.
For IPv4 with one line of configuration I can open many servers according to the mask I use for example with 10.10.10.0/24 I can open 254 servers.
How can I do the same for IPv6 ? I am able to add loopback interfaces but only for one host. Is it possible to add for a subnet ?
If not what is the max number of addresses that I can add ?
I also saw that it add the address only to loopback lo and I can add it to lo:3 for example.

I used to play with gw6c ( a client for tunnel broker ) It works well with fedora9 , fedora 10, but not with leonidas. my rpm is gw6c-6.0-0.4.beta4.fc9.i386.rpm ( a little old!) when I tried to install i have got this: libcrypto.so.7 est ncessaire pou w6c-6.0-0.4.beta4.fc9.i386 I try to make a soft link to libcrypto.so.0.9.8k, but nothing; The question :-Is there a solution for that pb - did you know a better client for non native ipv6 connectivity?

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.

After running a large update and rebooting a few weeks ago, I found that my internet connection had stopped working. My internal network still worked fine though, so it I know it's not the card itself or its configuration. After a bit of trial and error I discovered that simply running dhclient brings the connection up again, so it appears that something is interfering with the initial dhcp update to my ISP (or something like that; I'm no expert in this area. ) My usual policy in cases like this is to wait through two or three updates in the hopes that it's just a temporary problem, but it's been a while now and subsequent updates haven't fixed it.
I've tried looking around, but I can't come up with search criteria specific enough to narrow it down to my specific situation. I'm not even sure where to begin looking to diagnose the problem, nor do I know which package update(s) could've affected it. I'm not sure what might be useful, but here's the relevant entry in /etc/network/interfaces. I have it configured with a static internal address, with my router as the gateway.
Code:
# The primary network interface
mapping eth0
script grep
map eth0

Got Ubuntu Server 10.10 installed as a virtual machine (vmware). When i forward X through SSH (putty) i can start xeyes, xcalc,etc.
Now when i disable ipv6 putty can't set the display variable and i get "Error: can't open display". I haven't changed anything in putty or win 7 (the host system).
I disable ipv6 by putting these lines in /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Since I got the liquorix kernel installed on my machine I got an error of setting kernel variable error. net.ipv6.bindv6only at boot time, since it wasnt a big deal I never looked further into it, but now that I had some spare time and I didnt want to see any errors on my machine I found a solution for it, with a little googling all we need to do is read the /usr/share/doc/procps/README.Debian and bingo no more error i hope this help anyone else with the same problem. I did the 3rd suggestion on that file to load the module in /etc/modules cheers.

I have an issue on a few servers where IPv6 stops working after a reboot. 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 have tried adding a default Ipv6 route for Eth3 but nothing seems to work.

Linux server-1 2.6.27.19-5-default #1 SMP 2009-02-28 04:40:21 +0100 x86_64 x86_64 x86_64 GNU/Linux

I've just installed debian sid and see that I've the kernel 2.6.32. I was a bit surprise as on ubuntu I had the 2.6.35 and debian sid is supposed to be more up to date that ubuntu (maybe I'm wrong).So I checked what were the packages available :
mart@mart-laptop:~$ uname -a
Linux mart-laptop 2.6.32-5-686-bigmem #1 SMP Sat Oct 30 23:25:58 UTC 2010 i686 GNU/Linux

I'm recompiling my kernel on a dell latitude c600 running lenny as I type, and it's taking forever, so far upward of 4 hours.I think I'm getting drivers for ever piece of computing hardware since the univac So I googled "a kernel conf creator" and got [URL]... Its a nice, clean method for finding what hardware your using... you just run lspci cpuinfo make xconfig and put in all the info yourself. So I was thinking: this is exactly the kind of dull, repetitive behavior that computers were made for. Is there a program that can find my hardware info, and make the.config itself, with very little user input?Or should I reinstall debian on another partition and steal the .config from it? Or should I man it up and do it myself?

I had some issues with my system hanging on the automatic configuration of the install so I searched the web for the issue. After reading this thread: Hangs at end of SuSe 11 install I used acpi=off apm=off nolapci as the install options and it worked. My question is, do I need to add those options to the /grub/menu.lst or will the install do that?

I have Ubuntu 10.10 installed on my laptop. My ISP natively supports ipv6, but since last weekend, I do not get an ipv6 ip. When I use a live cd however, I do get an ipv6 ip. For as far as I can see, all settings (/etc/network/interface and the settings in network manager) are exactly the same.
Output of ifconfig:
Code:
eth0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX
inet addr:XXX.XXX.XXX.XXX Bcast:XXX.XXX.XXX.XXX Mask:XXX.XXX.XXX.XXX
inet6 addr: XXXX::XXXX:XXXX:XXXX:XXXX/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[Code].....
EDIT: is there a way to let the netwerk be automatically configured as happens during installation? It would be nice to start with a clean and new set of network config files as there were just after I installed Ubuntu on my system, without a full reinstall of my system.

I'm an Ubuntu/Kubuntu user for a while now and i hav Kubuntu 9.10 with ubuntu-desktop installed.
I have two hard disks and i had one of the partitions mounted automatically while startup. I did that by reading the first method posted here
HTML Code: [URL]
It was working good till i did the distribution update to Kubuntu 10.04. After the upgrade while startup, a message is displayed on the screen saying
Quote:
"Disk to be mounted at /media/miscellaneous is not ready or is not there. Continue waiting or press S to skip mounting or M for manual recovery"
I dont know what to do. I have to skip and then mount the partition manually. I think the entry i added in
Quote:
/etc/fstab
is still there.

I created a profile for Yast Backup and successfully executed it manually. However, when I set up the Automatic Backup with the same profile it doesn't work. It will start at the scheduled time and do the "search" part of it but it hangs before it creates the archive. These two processes (backup_cron & y2base) remains running and never terminates.
Here are the last few lines in the Yast log before it hangs:
Code:
2010-06-09 20:08:05 <1> londy(1957) [YCP] backup/ui.ycp:2037 subprocess started: true (PID: 1958)

I enabled Automatic Online Updates in opensuse 11.2, and set the frequency to "Daily", but after 24 hours I haven't seen an update. It may be because I had YaST still running and maybe the installed software database was locked.At any rate,ow can I verify that Automatic Online Updates are scheduled?

I'm running Debian server 5.0.6 and the latest stable version of Apache. I am hosting a website and it will stop responding after an unknown amount of time. In order to make the website work again I have to run /etc/init.d/networking restart. The server is running a static IP address and is not resetting when the website goes down. I don't know where to start looking.
