Is there a way to access today the openSUSE servers via IPv4? My ISP does not support ipv6, nor my router, and I can't install software right now in openSUSE, because it wants to access te servers via IPv6.
If would be grat to have the download.opensuse.org ipv4 address.
I really need to install some packages, they are required for my school project.
I have an OpenVPN(10.04.2 LTS) server running in bridge (TAP) mode. Its sitting behind a router and then a cable modem. The VPN works perfectly but I have a security concern. In order to allow the VPN clients to connect to the internet, I had to enable IPv4 forwarding on the server. Is this is a security hole? Can a hacker access my servers connection from the internet (without authenticating with OpenVPN) and access my network. Can someone use Ipv4 forwarding to access my LAN network from the WAN
I used this command to enable ipv4 forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
Without IPv4 forwarding my VPN clients can only access my LAN and router, but they cannot reach my modem or the internet.

After upgrading from 9.10 to 10.04, a hundred or so of (for example)
Code:
error (network unreachable) resolving '14.42.117.203.in-addr.arpa/PTR/IN': 2001:500:13::c7d4:35#53: 1 Time(s)
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 had some fun here, with my local Cyrus IMAP daemon. I "updated" the machine to openSuse11.4 (from 11.2) by doing a fresh install. Because some of my involved HW here isn't capable of IPv6, I switched it off using yast2:
Netzwerkgeräte/Netzwerkeinstellungen [my translation: Network devices / Network Settings] Globale Optionen [global options] Removed the mark on "IPv6 aktivieren" [activate IPv6]
Then I had a hard fight with Cyrus IMAPd, mostly caused by user brain damage on my part... But one thing really looks like a problem on the Suse side of the fence: My /etc/hosts missed the "localhost"-entry for IPv4 ! This was the contents:
Code:
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
127.0.0.2 godot.site godot
[Code].....
I haven't seen this effect on 11.2 here and I haven't seen it on "my other" machine (running 64 bit version of Suse 11.4). But there I think IPv6 is still activated. I will check this, as soon as I get there.
Should this be reported as a potential bug in 11.4 ? Or is there some way, I could have messed up this. (No I didn't edit /etc/hosts by hand, before I corrected this thing)
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).
View 2 Replies View RelatedProblem with my Internet connection. I can't connect to the update servers. I don't know why. It's a brand new installation, not a week old yet. I can't install the support for restricted media for example. The servers won't refresh in YaST. It tells me it can't download the repomd.xml.asc.
The other problem is that some servers on the web won't load for me either.
For example, I get most of my local news from The Toronto Star, and I can't connect to it's website at all.
I can from Windows (I dual boot) but not SUSE. I don't think its a problem limited to that one website either. I am able to connect to most websites though.

Disabling IPv4 packet forwarding but i already changed it to 1 at sysctl.conf One of the online forum says i need to configure the named.conf deleted some and run it(named.conf) and successful but still when I run network service I still get the :"Disabling IPv4 packet forwarding: net.ipv4.ip_forward = 0" The network is getting the IP range but it doesnt get any Internet connection.
Current problem: fresh, clean install of Ubuntu 7.10 on known good hardware does not use/produce/get/have an IPv4 associated with eth0, so cannot connect to my home network for Internet access.
Background: Have been wanting to build and maintain a home file server for some time now. Have also been wanting some hands-on practice to help me progress from Noob to Intermediate, eventually advanced Linux Tech. (I have two decades of tech support experience, but only small fraction of that using command lines and almost zero Linux.)
Anyway, every time I download and attempt to burn a recent distro on my Vista Shuttle, I only end up making drink coasters and mini-frisbees. so I thought that I might have better luck if I used a Linux Workstation to download and burn a server distro.
That's where I an now. I took one of my fully functional WinXP systems offline, replaced the WXP HDD with an old 3.2 GB, dug out my 2008 edition Linux Bible, popped in the DVD that came with it, and installed Ubuntu 7.10.
Everything else seems to have progressed smoothly, but I cannot seem to get the onboard Via chipset ethernet controller to talk to the router. When I run "ifconfig" in Terminal, I see IPv6 info, but nothing for IPv4.
When I try to configure eth0, it doesn't matter whether I set it up for DHCP or static... nothing works.
Is there a command line tht I can use in Terminal to manually configure eth0 to use IPv4?
I have tried clean installs of Knoppix v0.6, Xandros 2.0, and Ubuntu 7.1... same issue with all. I cannot seem to get eth0 (via chip on mobo) to get/have/use IPv4. ifconfig shows only IPv6. (I cannot paste any info because linux desktop is on different box.)
End result is that I cannot get the linux desktop to connect to my lan, either with dhcp or with static ip.
I have a belkin router configured as my gateway 192.168.3.1 and nothing fancy with the setup. I have dhcp open for 192.168.3.245 thru ...254 and at most there are only 4 systems in home connecting with dhcp at any time. all other systems have static addresses.
I have two decades of desktop and lan support under my belt, but relatively small amount of command line experience and almost no history with linux (unless you count a dozen unsuccessful attempts to burn linux distro install discs on this Vista desktop).
Therein lies the start of my prob. I need to build and manage a fileserver for my home, but cannot seem to get a working installer cd or dvd to burn from anything I download.
So I said to myself, "Self," I said, "you're a tech. Build a workstaion, use the DVD that came with your Linux Bible (2008 Ed.) to install one of the linux distros on it, then download a recent, stable server distro and burn it using the linux workstation."
Unfortunately, if I cant get an ipv4 connection to my home network, I cant get out to the Internet to download any newer ISO files.
So what am I missing or doing wrong? How do I tell linux to stop trying to use IPv6 and let me use IPv4?
BTW, eth0 works just fine if I install Windows on that PC, so I know its not bad HW. Could it be a driver issue? Or do I need to use some Terminal command to turn off IPv6 and reconfigure eth0 for IPv4?
I am using Squeeze and all appears OK at first... I have a DHCP lease, PING to router works, apache servering fine in and outside the network, Epiphany seems to connects to default debian.org only, BUT I cannot connect to any other websites and apt will not connect to any servers. I installed once, tried to fix problem, gave up and reinstalled and still have the same problem.
I unistalled Network Manager thinking that was the problem, but still the same issue. Is there a default firewall blocking certain connections or am I missing something I'm supposed to know about? I installed some non-free firmware in the beginning of install and all worked... and I connected fine when downloading packages during install.
Can someone explain me ipv4 notation like:
192.168.1.0/255.255.255.0
Does it mean "any host on 192.168.1.x" network?
how to make a Ubuntu 10.04 server VM look for an IPv4 address if it doesn't seem to by default?
View 3 Replies View RelatedI'm working in windows, and that's why I have been able to access the network. In F14, I was able to access the router address while the internet access ain't. Tried restarting network, and still the problem persists. Tried [URL] and the only thing that i've infered is that IPv4 Failed: FATAL plus, the routing table showed 0.0.0.0 as one of the entries (Gateway). So, i've deleted the wired network configuration from the Network Configuration and checked whether the os would pick it up automatically. It still didn't work.

View 1 Replies View RelatedAfter installing 11.4, I need to type in the command to update the firmware for a broadcom wifi adapter. Then I needed to reboot, twice, before the system knew to use the adapter (where the adapter wifi light goes from orange to blue).
Then I needed to add my wireless network and type in my key. But the key does not take. If I click on my wireless network icon, it just re-asks for the key and does not connect nor give any other message. Network icon continues to display no connection.
So I need to reboot again.
When the system starts again, the adapter is blue, I click on the icon for my wifi network and it connects without asking for my key and I can then set to start my wifi by default.
Now my wifi works fine.

View 5 Replies View RelatedI am using OpenSuse 11.3 and Network Manager is giving me a headache by not connecting to WEP based wi-fi network.It works in a wi-fi at my office while at my home, it shows / detects the network but keeps asking me over and over.
View 3 Replies View RelatedI installed OpenSuSE 11.3. The only "extra" package I put in after the install was VirtualBox-ose. The firewall is disabled. I gave the machine a static IP address. I can get to the Internet from the machine. I enabled sshd to start on boot with "chkconfig sshd on" and also verified the service is running on the machine. I can ssh user@localhost from the machine as well.
When I try to connect to SSH from another machine, I get a connection refused. I verify that the firewall is down. I also try to get to VNC -- same problem: Connection refused. I ping the machine for fun. If I try to SSH again, it sometimes gives me a logon? I would check the server logs for the connection refused, but I wouldn't know where to look. I started in /var/log/messages, but nothing seemed to jump out there. I also find it strange because I can RDP to a windows guest running under VirtualBox. The Windows guest uses Bridged Network and DHCP.
I also find it interesting that I sometimes type a "ping google.com" from the 11.3 box and it will just hang - no output. Then I open firefox and get to the internet. All of a sudden, ping starts to give output. Could this be a neetwork card issue? A configuration issue? I don't know where to start.

View 4 Replies View RelatedI am relatively new at Linux and am having some problems with an install of openSUSE 11.2. I installed 11.2 on my Thinkpad X31 dual boot with WinXP. It seems to work very well except the network. I looked up swerdna's instructions on setting network cards up. I used YaST to try and set the system up as described in swerdna's instructions. Everything looks fine my network card and wireless card show up in the overview settings screen and everything sets up fine. But when I exit YaST the network doest show up no icon in the system tray and it doesn't even try to connect.
I did go into hardware to see if it was identifying my hardware and my network card shows up as "Thinkpad R40" and the wireless shows up as Cisco Aironet Wireless 802.11b. As far as I know this is correct. I have tried three other distro's and this one has gotten the closest to working so far.
the thing is that I cant use Network Manager to connect to Internet, because it simply do not connect. The connection, although, awailable throught yast when i choose "traditional method with ifup", so everything is just fine, but if i need to reconnect, i have to reboot. How do I setup a !working! connection through Network Manager, or maybe i do not do something properly.
