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 experiencing very slow internet speed while downloading files from internet. Although torrent (KTorrent) download speeds are okay. I am using 'rekonq' Web Browser. Konqueror is slower than this and Firefox is the slowest. Thats why I have uninstalled Firefox from my Suse 11.3 KDE. I went through the guides mentioned here:
Disable IPv6 But the images shown here in the first post (by caf4926) [URL] have slightly different configuration from my computer. (My account does not allow me to post attachments). In the pic 2, Do we have to select the option: "User Controlled with NetworkManager" before unchecking the Enable IPv6 option.
I've just started using ufw with the frontend gufw. I've configured it like this:
Accept everything in and out as default Block incoming FTP connections from a certain IPv4 address (brute-force for days)
Today I noticed that IPv6 connections don't work anymore. The connection to two hosts (IPv6 only) times out. As soon as I disable ufw entirely, the connections work again. The host I want to connect to is:
2001:638:a00:f00b:200:1cff:fedb:d38f port 7337
2001:638:a00:f00b:a00:6ff:fe07:cda2 port 7337
These are small telnet servers that print out a number (temperature nearby) and close again. I'm logging those values in a database.
Is ufw not IPv6-capable and blocks things it's not supposed to?
Update: ufw seems complete garbage to me... You can't even configure it while it's disabled! How am I supposed to safely activate it when the first thing it does is blocking all communications? I can't even configure it to let me in before I configure it to keep me out... And then, even if I explicitly let it pass port 7337, it still blocks it through IPv6.
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 have seen several threads lately about slow internet connections here and elsewhere, but I haven't seen anyone post a reply about blacklisting ipv6 so I am curious as to why?Is ipv6 enabled only on certain distro's or is there some other reason that it's not mentioned?
<If anyone wants to try it, to see if it would work for them>
On Slackware 12.2 and Salix 13.0 just add "blacklist ipv6" to the /etc/modprobe.d/blacklist file. I'm not sure about non-slackware based distro's. Unfortunately, I don't know any way of doing it without rebooting.
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.
Is it possible to setup samba to work over IPv6?
View 2 Replies View RelatedI 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.

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 openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections.

I first tried an upgrade from 11.3 to 11.4 and lost Internet Access, so i re-loaded 11.4 from scratch on clean partitions.
I am connected to my wireless WPA2/PSK connection, have an IP, am able to see the network.
I turned off and disabled the SUSE firewall.

I just finished a fresh install of 11.3 on an HP 7900 small form factor and have no network connectivity. In Network Tools eth0 shows the state as inactive. Network Connections didn't have a connection, so after letting it create one there is no MAC address. I copied and pasted the MAC address from Network Connections eth0, set up a static address with default gateway, netmask, etc. all set appropriately and rebooted. Still no joy.
I want this to get an address via DHCP, I just set up a static address for testing.11.2 sensed the NIC without issue, but 11.3 doesn't seem to like me right now.I wanted to get this deployed on 40 machines today. Oh well.
network manager isnt showing any network interfaces. ifconfig shows wlan0 and eth0 and internet is working. how can i get network manager to manage those connections?

First a warning that I'm so clueless it hurts. Initially I entered the Linux world as a solution to my blue screening Alienware Aurora desktop (which later fried anyway ironically enough). I decided to give up on Windows for everyday use cause you can't strangle an operating system. My first and there after Linux experiences have been fantastic. Internet works without prompting through various distributions of Ubuntu, Mint, and KDE with the exception of enlightenment.
But now I come to openSUSE 11.4 and as my title suggests I'm having a hard time connecting to the internet. I've got a wireless card and router and all that jazz but I can't even select the options for wired or wireless connections under Network Connections in the Network Management Settings. Everything is greyed out except for VPN. I even have the desktop wired to the router and it still is not giving me any indication that it will connect.
I'm wary of trying to enter ip addresses and things of the like because I honestly don't know what i'm doing here.
My router is a Netgear N150 Wireless WNR1000 and in the Kinfocenter under Device Viewer I found my wireless card to be a RaLink RT2561/RT61 802.11 g PCI and my wired device thingy to be an Intel 82540EM Gigabit Ethernet Controller.
Okay so on WebUpd8 website, (url), I found a way to disable IPv6 and I was hoping to get a little more of an understanding of if I should or not from comments there, but unfortunately I haven't gotten enough to say let's do that. So I figured I might get a better understanding on here.
I am not very familiar with IPv6, but to my understanding its a newer thing that's rarely found currently with ISPs, but can be a security issue now.
Anyone know how to disable IPv6 but still use IPv4?

View 7 Replies View RelatedMy 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?
