OpenSUSE Network :: Network / DNS - Can't Access Any Internet Resources Or Router
Jul 30, 2010
I'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager
OpenSUSE 11.3 x64 KDE I dont know what happened it is a new install thats been running for 2 weeks . Now for some reason I can not access the internet or the router. Samba is working with Dolphin I can browse shares on local network both Windblows and Linux and ping local IP's. But I can NOT ping my router (the default gateway IP) with this box or access it with firefox so no internet. A VirtualBox of XP Pro running on this box has no problems with its bridged adapter getting out and seeing the router. I disabled the firewall, added gateway IP to network settings, disabled ipv 6 from the get go, added service provider dns's to nameservers tried opendns servers also.
I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.
I've seen lots of other issues similar to mine on this forum and others, but had no joy in resolving this problem. I can connect to my router web interface, using both wireless and ethernet cable, but cannot connect to the internet with either.
I can't ping any IP address or hostname. When I type route into the terminal, I get:
Code: Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.1.1 255.255.255.0 UG 0 0 0 eth0 192.168.1.0 * 255.255.255.0 U 1 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
There are extra 'default' destinations in there, because of things I have tried from other posts. I have had internet working. It was working for months, but it all stopped working when I installed Skype, vpnc and kvpnc (VPN Client GUI). I don't know if this is just coincidence. I did get connected to my VPN, but shortly after installing Skype, everything outside my local network (i.e. internet and VPN) stopped working.
I'm writing this from another laptop on the local network, so the internet obviously working fine - just not from my own laptop. I'm running openSUSE 11.1 (i586), KDE 4.1.3 "release 4.10.4". And in "sysinfo:/" it says Network Status: "You are online" Like I said, internet doesn't work for both ethernet and wireless. Can't ping anything. I can access router web interface at 192.168.1.1
installed openSUSE 11.3 and round that both wireless and ethernet connections could connect ok to my router but couldnt access the internet. I think its a bug because I didn't have this issue in previous versions of openSUSE.
The solution is to go into the ip settings in the wireless configuration, select the option to manually assign ddresses (not DCHP) and
- enter the ip address of your router in the default gateway and DNS server addresses
- manually assign an ip address to your computer rather than have the router do it
- it has to be in the same range as your router -n normally 192.168.1.x where x can be any number not already used.
I've just spent the entire night trying to get my computer to share Internet with my laptop. I have DSL Internet with the modem configured to bridge mode. On the openSUSE server I have two NIC's. When setting up the DSL (pppoe) it created a dsl0 which is using the NIC eth0. So now I have dsl0, eth0, and eth1 I configured eth1 for DHCP server. When I connect with my laptop using DHCP it gets an IP address just fine. However I can't access the Internet. I think my problem is in the Kernel IP Routing Table. Here is the output from /sbin/route -n
dsl0 obtains IP from ISP eth0 is set to DHCP although that confuses me because how can the same NIC have two IP Addresses? eth1 static IP 10.30.60.1
I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo) - error code connection failed - error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error - no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)
I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 220.127.116.11 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 18.104.22.168 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !
Is there a network trouble shooting guide for OS 11.2 that I could follow? I've shot myself in the foot so I should try to fix it.
I changed the DNS server addresses and the number of IP addresses on my router. I then set my Linux system to use static IP addressing and edited the network settings for my network adapter accordingly. I can now no longer get to any web-site.
By contrast, I also updated 1 of my Windows computers in a similar way; it continues to work without problem.
I am trying to get internet connection on Open Suse 11.2 through my wireless connection. I can connect to my network but there is no internet connection. The internet connection does work with other Linux distros and with Windows 7 laptop and Windows XP machines. I tried turning off the firewall but still no connection. What is even stranger is I can ping Google but in Firefox I cannot go to Google.
I'm kinda new to this, and usually i get help from a computor technician at school. BUT sins its Saturday, i cant get any help, and i realy need it. Well my problem is that i cant get any internet access using eth0 at my computer. I dont know what i have done wrong, if i have done anything wrong, it just reinstalled. ANd i dont know how to config it.
Brand new to the OpenSuse project. I'm have an old AMD Duron running 11.3 and I am having no luck in connecting to the www. I'm using a D-Link usb wireless adapter. I seem to have an IP address for the PC. here is the print from ifconfig:
I just did a large patch on my opensuse11.3 system (upgrade of all installed packages), and whilst my network interface works, I cannot get past my router onto the internet.
I can connect to other computers on my network (here at home), I have an IP address via dhcp from my router, but I cannot get internet access, either from thunderbird, firefox, or simply by [URL] Clearly the computer was connected to the internet just fine minutes before since I did the large patch! Also, my other computers CAN still connect to the internet.
how i can debug it? It is just too coincidental I have upgraded everything and now somethings amiss!
If it's relevant, my router is a netgear WGR614v9.
A few things I've tried...
Code: linuxthinkpad:/var/log # /sbin/route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth1 link-local * 255.255.0.0 U 0 0 0 eth1 loopback * 255.0.0.0 U 0 0 0 lo
I setup the hostname for my linux machine to Linux. If I try ping Linux from the same computer it works. If I try from another computer inside my network the host can not be resolved. If I ping the IP from another computer it works.
I take a look in my router at DHCP client list and my linux machine doesn't have the Hostname set up.
How to broadcast the hostname to the entire network?
All settings are correct as far as i can tell. The wep key works on all my windows boxes. When i have connect automatically enabled it never tries to connect. if I go to edit it it pops kde wallet up i put in credentials. wallet goes away then nothing happens. if i double click connection to my router also nothing happens. I have the wep key in there and i even made it visible to make sure.
So up until I updated from Opensuse 11.3 to 11.4, I hadn't any issues with my network connection. At least none worth mentioning. Once I installed 11.4, I've had weird issues with varying lengths of connection. Sometimes I can't connect anywhere, sometimes I can only get to the router, sometimes I'm 100%. I'd fiddle with YAST until everything worked. I honestly have no clue whether or not anything I did had any effect.
Enough of the iffy history, here's what's happening now. For the past few weeks up until last night, I have been at 100% connectivity. I never turned off my computer until last night (it just shut itself off, like the cord was unplugged. I dunno what happened, maybe it was my foot, maybe the PSU. I think it has happened before.). When I turned it back on, I was only able to connect as far as my router (192.168.1.1, a D-Link Gaming router that has always been very good to me). I could not make it to my modem (192.168.0.1, a Quest DSL modem. Once I can get here, then usually I'm good to go 100%).
I tried again this afternoon, and no change. I then get the crazy idea to unplug the ethernet cable from it's PCI-card home and return it to the onboard port (which I long ago declared defunct). Immediately after plugging it into that port, I ran "ping 192.168.0.1" and I started getting returns. I open up Firefox and try to load an external page, and nothing happens. I go back to the console that I was pinging from, and it had stopped. I start pinging my router, and no luck. What I conclude from my little experiment is that the router is not at fault.
1. It did not change at all between being at 100% and being at 0% after reboot. 2. I was able to get returns from the modem, past the router, for a brief period of time while using the defunct ethernet port.
Since I never had these problems before updating to 11.4, I'm inclined to believe that it was the update that started these problems.
recently ran into a problem with my internet access. Im using open suse 11.2 on a Dell Vostro 1520 laptop. I managed to get my wlan running and i can use firefox to access my router. In my router the laptop is also showing as connnected, dhcp reserved an ip for it.However if i try to browse the internet, no page is loading, actually no software that needs access to the web is working.
i've installed opensuse 11.3 x86_64 and everything works great. after install updates and restart i cannot access internet from wireless connection. Knetworkmanager says it is connected, i have a dhcp ip, gateway, and cannot access internet.... i tried to configure from yast and cannot access internet...
I need to implement at my sister this kind of connection: She is connected on Local area network that has about 50-80 pc's, but for internet access she must start an pppoe connection. For now when she wants to use lan she must put her local address (ps: they dont have dhcp), for pppoe she uses dhcp. Problem is that on that way she can't access lan and internet at the same time. She must disconnect from lan and then start pppoe connection and vice versa. I'm intrested if it is possible to have lan access at the same time as internet access. some kind of tunel through lan up to isp. I was googling little and so PPPoE tunneling. Is it that what I need here?
I've been running Suse 11.2 KDE on a 64-bit Dell Studio 1535 since last week's release, and have had no trouble using Firefox. At some point today, however, it stopped accessing webpages -- or, when managing to grab a page, it would do so without full html rendering. 95% of the time I get an error splash, while the other 5% I get some sort of truncated page that looks nothing like it should. Konquer and Opera work fine, as does KMail.
I tried deleting the profile.int file (no luck), then uninstalled/re-installed (no luck), then uninstalled and deleted every Mozilla/Firefox file I could find in order for a fresh install -- but this has not worked after several attempts. I still cannot get Internet access. How to completely wipe-out Firefox in order to allow for a totally new installation?
Recently i started going into OSes other than Windows. So, i installed openSUSE 11.3 32bit on my system in dual boot with Windows7 32bit. Everything was okay But i couldn't find any drivers for my laptop. My problems are :
1. cannot access NTFS drives. 2. cannot connect to the internet through LAN 3. cannot connect to the internet through Wireless.
Computer's Configuration : Dell Inspiron 14r Intel Corei3 processor Both the operating systems run fine otherwise
I'm trying to setup a wireless AP with my old asus eeepc, so it can act as a repeater to connect my android device on the other end of the apartment. I've already created the Wireless Access Point using hostapd. It took very little configuring, just changed from mode 'a' to 'g' and changed the channel from 60 to 1 and It was all set. Next I setup a dhcp server. Also simple enough using yast.
Up to this point, I was able to connect my android device to the newly created wireless network. However It doesn't have internet access. I guess I have to configure iptables for this, but I find it incredibly confusing! Here are a few specs to help with any examples: The laptop is connected to the internet through eth0 with IP 192.168.2.120 Hostapd is using wlan0, and I'm pretty sure it created mon.wlan0 So, to sum up, when I connect my android device to the network I can, for instance, see what ever pages apache is currently serving on the laptop, but can't access the internet.
I would like to be able to monitor which programs are allowed to access the internet, but a search for programs to do this has turned up nothing. Preferably, I would like a notification to come up every time an application uses the internet. Is there any (n00b friendly) software available to do that?
Just today I installed opensuse 11.3 on my Compaq CQ61. Even though I am able to connect to networks (both with an ethernet cable and wireless) I don't have internet access. I have used opensuse for a very brief period in the past and I had no such problem.
I got 2 routers, one is on 192 and the other one is 10. There seems to be a problem when I am accessing 10 network from 192 although, when I do the opposite it works correctly. router configured with 192 is Huawei 510 router configured with 10 is Dlink - DIR 618 I have even tried to open 2nd interface on Huawei 510 even then it doesn't seem to work.
In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.
Installed a security update for samba tonight via Opensuse updater.Now, when trying to access my home network an authentication box pops up (never used to)Asks me to enter authentication for my home network.I enter my username and password and hit enter. After a few seconds the authentication box pops up again askingfor the same indicating I have entered the wrong username / password combination (which I know I have not).
I install from openSUSE-11.3-NET-x86_64.iso. Installation was succesfull, but after install all packet on test internet / update was error. And after log in in installed system internet not work. I use router with DHCP
I'm on opensuse 11.4 (11.3 won't work with my monitor).
My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.
I also tried this command: echo 1 > /proc/sys/net/ipv4/ip_forward
but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?
