OpenSUSE Network :: IPv6 Stops Working After Reboot
Aug 10, 2010
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.
uname -a
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
Code:
route -A inet6
Kernel IPv6 routing table .....

I updated my NetworkManager from version 0.9svn1128615-2.2 /opensuse/repositories/KDE:/KDE4:/Factory:/Desktop/openSUSE_11.2/i586/) to the newest version 0.9svn1128615-138.2.The result was, the after reboot an error message occured, saying that the KNetworkmanager is not working and it would be not able to start the program !Did anybody else have the problem with this newest version?

I am using opensuse 11.4, libvirtd 0.8.8, virt-manger 0.8.5.
If I want to reboot a virtual machine (typing 'reboot -n' in the VMs console) the virtual machine stops insteads of reboot.
The virtual machine is also opensuse 11.4
Afterwards I have to click 'run' in virt-manager.
Then the vm starts and remains running til the next reboot.
If I try to reboot from comandline by typing 'virsh reboot <vmname>' I get the message
error: Failed to reboot domain <vmname>
error: this function is not supported by the connection driver: virDomainReboot
What is wrong with my setup?

Sometimes my file share network stops working,and will then work again.I'm lost with this problem. The server pc is a Zenwalk pc.The other pc is a win7 pc. This error only occurs on Zenwalk. When i run puppy from the live cd the file shares are always visible,without fail.Under puppy i use pNethood. When the ping command is used there is no problem, and the pc name can be pinged.This is shown below:

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.

I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?

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?

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.

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 just recently erased my hard drive and installed ubuntu 9.10 all over again. I updated as expected and everything was going well, until, my internet stopped working after maybe 40 mins or so after a successful boot. Now this same thing happens every 40 mins and I have to reboot the computer by forcing my laptop to shut down by holding down the power button. This also made me aware of another problem when restarting or logging off my laptop. The laptop hangs at that terminal-syled screen and the underscore blinks and fails to shut the computer down/log off. I resort to holding down the power button to restart. I am using a wireless connection with WEP key protection.
Atheros network chip
Laptop Acer Aspire 5532
It just happened again..... I am typing now in tomboy notes....
Time to restart again......
I also try to open terminal and it fails to function (after the internet stop working), any reason for that? I would also like to note that the signal strength decreases as time passes by.......

I have a wireless network using this driver:
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.

How do I assign IPv4 and IPv6 static addresses permanently in OpenSUSE 11.2? Currently I am only able to assign either IPv4 or IPv6 static address not both. I cannot find even the interfaces file(/etc/sysconfig/network/interfaces).

In an IPv6 test environment I have installed an openSUSE 11.2 system. I have also installed telnet and it works with IPv4 (I can open a session from a Windows console with "telnet ipv4addr").
If I try to open a session with "telnet ipv6addr" I get the response: "Connecting To ipv6addr. Could not open connection to the host, on port 23: Connect failed".
Does the telnetserver support IPv6 or did I something wrong?

this is with both network manager and WICD, a problem i've had since i got ubuntu - multiple wipes and reinstalls the wifi is supported out of the box, the problem i've randomly run into since installing is, it will randomly stop detecting networks "no networks detected"
i've noticed over time as this as been happening, that it usually happens whenever there is a high load - multiple videos going on multiple tabs, videos queued up etc. its never happened during regular browsing - theres always a lot going on when it happens, almost like it collapses. the only way to fix this, is to quit the manager - shut off the computer (restarting doesnt work) and then it comes back after

I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.

Using 10.04 happily for some time, I shut the machine down today and when I started it back up there was no network.
I've tried to fix the problem myself, but probably made things much worse! I've tried to reinstall the network manager, manually bring up eth0 with a static ip address (it was happily using dynamic earlier today). I even followed some instructions for manually configuring a network interface added an entry to the routing table (which I suspect will turn out to be a huge mistake). No matter what I have done, I haven't even been able to ping my router.
I am not sure what if any of the following is useful: my router is 192.168.1.1 and is set up as DHCP server
ifconfig Code: eth0 Link encap:Ethernet HWaddr e0:cb:4e:32:2e:10
inet addre:192.168.1.5 Bcaset:192.168.1.255 Mask:255.255.255.0

I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.

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?

Using 10.04, everything working fine every day since the install a month or so ago. I shut down the machine normally, when I returned a few hours later it started up without a hitch, but without network. I found a thread suggesting the following (in the case of a failed suspend, which did happent to me a few weeks ago)
Code:
service network-manager stop
rm /var/lib/NetworkManager/NetworkManager.state
service network-manager start
but it didn't help.
My ifconfig looks like this

This is an intermittent problem. My mouse works on boot, but stops working periodically. Once it stops, I have to reboot the computer. The problem is more than a little annoying. My hardware and software is as follows:
*AMD Phenom X3
*Integrated geForce 8200 GS
*Opensuse 11.3 64-bit
*Mouse - microsoft wireless comfort mouse 2.0
*Keyboard - microsoft wireless comfort keyboard 1.0A
I am not sure what logs I should attach. The contents of /var/log/messages leading up to the mouse stopping is as follows:
Code:

My mouse stops working under vmware I have ESXi 4.0. Reboot or (Ctrl) (Alt) (Backspace) fixes the issue. I'm seeing the same thing in OpenSuSE 11.3 running on ESX 3.5. Using the open-vmware-tools as part of the OpenSuSE install. Odd thing is that I have (3) 11.3 machines, 1 has never shown this behavior, I seems to have gotten another to stop by changing the KDE Activity setting Type to "Plain Desktop", and 1 that for the life of me I can't get it to stop.
The first one has been upgraded from 11.1 -> 11.2 -> 11.3. The second was 11.2 -> 11.3, and the third is a fresh install of 11.3. I'm able to fix it for a limited time by logging out or restarting X with Cntrl+Alt+Backspace. I've tried restarting the vmware tools without luck. I'm wondering if it is an Xorg bug.

Last night I upgraded the kernel to 2.6.34.4-0.1-desktop and now X has stopped working. I can go into run level 3 OK.
I have tried removing the xorg.conf file, using a copy of the install xorg.conf. I have also tried reinstalling the ati drivers
-rwxr-xr-x 1 readyp home 101178081 2010-08-07 23:45 ati-driver-installer-10-7-x86.x86_64.run
-rwxr-xr-x 1 readyp home 103164399 2010-08-29 21:25 ati-driver-installer-10-8-x86.x86_64.run
the ATI drivers stop at 75% and do not complete.
If I go into run level 3 and run startx the screen goes black and all the keys stop working (Ctrl-Alt-F1 etc..)
I can attach the Xorg.0.log if you like, but it does not look strange.
I am sure the hardware is OK as I have my system dual boot with 11.2 and 11.3.

I use static IPs in my network and IFup(traditional) this one is dual boot..when the boot sequence is at the point of assigning the Ip it counts down and fails. But after startup I can do a network restart and it assigns the IP properly. I am running 11.1 and also had this problem with 10.1. I am using /dev/shm mounted as a tmpfs as
the system seems to move a little faster this way and I recall reading that fglrx (ati proprietary driver) needs it. So here is the weird part If I do not mount /dev/shm it assigns the IP properly on boot....if I mount /dev/shm it will not. I just recently discovered this as with 10.1 I just lived with the problem...but on a dual boot machine it is really a pain. Does anyone have any clue where to look for the issue?? I have tried emptying shm and it of course does not matter as it is a ram device.
