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.
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 have two linux servers, I tried to ping from one linux box to another and vice versa but error message is "connect: Network is unreachable" Where as If I tried from windows machine I am getting the reply from both the servers. C:Documents and Settings>ping bnkprod

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
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?
I am plagued by the following error when attempting port forwarded connections to my minecraft server. Port forwarding is good and test ok on router based firewall. No iptables entries. Natty N, all updates current.

Some discussion indicate jvm network connection issues related to ipv6, but they are old posts.
messages appear in syslog each day. Each URL has from 2 - 6 attempts at various ipv6 addresses. My question is why is bind9 trying to resolve ipv6 addresses? I have done nothing to enable or disable ipv6 and thought that if not explicitly enabled I would not have to be concerned with it.
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.
I recently installed Fedora 10 and I'm trying to install a driver for my HP Deskjet F4200 Series All in One printer. I downloaded the proper hplip file and when i go to install it in the terminal it gets to the very end where it is trying to install the missing required dependencies. When it checks for the network connection it comes back saying "error: The network appears to be unreachable. Installation cannot complete without access to error: distribution repositories. Please check the network and try again."I am connected to the internet through hardwire cable (also tried it through wifi) and have no trouble accessing internet through mozilla or downloading packages elsewhere. Any ideas on why my terminal won't recognize my internet connection??
I installed Fedora 10 and are using KDE. I struggled to get my network up and running - error for ping was "network is unreachable". I eventually got it right by modifying my ifcfg-eth0 file manually.
Now I'm trying to install with yum, but yum fails to connect, probably because of the proxy. I've set the proxy in <System Settings><Network Settings><Proxy> but it doesn't allow me to also add the authorization - greyed out. I've chosen the manual configuration of proxy.
1. How can I enable or allow the adding of authorization in the proxy dialogs or
2. Where is the proxy file which I can modify from command line (and how)?
I am facing two issues with CUPS - 1. I have installed cups 1.3.9 over OpenSuse11 x86. Please check below -
cups:/usr/share/cups/banners # cups-config --version 1.3.9 cups:/usr/share/cups/banners # cat /proc/version Linux version 220.127.116.11-9-pae (geeko@buildhost) (gcc version 4.3.2 [gcc-4_3-branch revision 141291] (SUSE Linux) ) #1 SMP 2008-12-04 18:10:04 +0100
I have added few printers over there and everything is working fine. I can also able to add - delete - modify any printers from "yast2 printer" command. I can also able to browse cups web interface via http://cups:631, but when I am going to manage the printers (start - stop - delete etc), none of the buttons are working in firefox5 not even in IE also. Older version of firefox is giving error as "This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection." All other buttons are working properly.

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 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 installed openSUSE on one of my work system. The network port wasn't working when I was installing, but works fine now (checked in Windows). But for some reason, I am not able to configure the network. I used both Dynamic and Static IPs (both work fine in Windows) but still no go. I am using Yast Control Center for this purpose. I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.
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?
setup my static network connection Here are my details :
IP : 172.16.152.137 Subnet : 255.255.255.192 Gateway : 172.16.152.191 Primary DNS : 172.16.0.1
but after this setup when i restart my network #service network restart while bringing up the eth0 the following message is displayed before [OK] - RTNETLINK answers : Invalid Argument now it seems either this setup is wrong or not sufficient to set up the connection, whenever i try to ping 172.16.0.1 it showing connect : Network is Unreachable
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'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 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 am running vsftp on one of my systems and when trying to connect to it it errors out with this: vendion@Loki:~> ftp 192.168.1.100 Connected to 192.168.1.100. 500 OOPS: could not bind listening IPv6 socket
I have tried stopping the firewall and even disabling IPv6 nothing changed, any clues as to what is going on?
Looking further, I note that /etc/init.d/networking is not symlinked into anything other than the rcS.d directory. It's been a while since I've been tinkering at this level, but I understand that there should be a symlink from rc2.d/Sxxnetworking into ../etc/init.d/networking. So I wonder where eth0 is getting configured.
I am trying to set up a virtualized ubuntu server in a local lan.In short : The server does not always answer to ping/ssh/whatever, but sometimes does, it seems completely random and dependant on the clients, it drives me crazy, what can I do to track down the problem ?In long : I will give the exact environment further down, but first the symptoms :A very strange network behaviour : the server does not always answer to ping/ssh/whatever from another computer in the LAN. It *seem*s completely random if it does or not, however I have identified some facts :- it is able to ping any computer in the LAN, or even outside (using IP or hostname) so it's connection seems ok.
- it is able to ping itself using "ping localhost"- the hyperviser is always able to ping it, however the *first* ping always fails (ie 3/4 first round then it works fine).now for the strange/random facts :- from my linux client, I can usually ping the server for about 10 minutes after I restart networking (in the ubuntu server), then it does not answer to ping/ssh/whatever anymore (though it happened that it suddenly came back for a while)- from my colleague windows client, we can ping the ubuntu server (same as the hyperviser, 3/4 first round), even when the linux client can't anymore- from my virtualized windows client, it is equal to my linux client (does not work fine)- from another linux client, same (does not work fine)- from 2 another windows machines, it does NOT work either !Now for the environment :- Hyper-V is the hyperviser on a DELL computer (not my fault, didn't have the choice)- Ubuntu server 10.04 standard install, with the synthetic network drivers activated in the kernel and defined in Hyper-V.
- A static IP- All computers in a LAN with mostly windows servers (such as DNS, AD and exchange servers)- there is another virtualized server (windows) on the same hyper-v global virtual network, with its own IP, and this one pings perfectly fine from any client.- the hyper-V also answers to ping
This morning it would not boot; when I tried to wake up the system, it gave me a bunch of errors, the last ones being as follows: "mount error: could not resolve address for servername: No address associated with hostname mountall: mount /media/shares  terminated with status 1" I am writing this in Win 7 since I lost ubuntu. I am using ubuntu 11.04.
