OpenSUSE Network :: Network Connection Fails To Go Past Router

May 16, 2011

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.

OpenSUSE Network :: KNetworkManager Connection - Never Obtain An IP Address From Wireless Router

Feb 24, 2010

I have an open WEP wireless internet connection with a security key. KNetworkManager can never obtain an IP address from my wireless router, but I know that the router works because Windows can connect correctly and Ubuntu's NetworkManager can connection correctly. Does anyone know what is happening? KNetworkManager just asks for my security again and again and again after it fails to connect.

OpenSUSE Network :: Mobile Broadband Connection Fails

May 22, 2011

I have a Huawei E173u-2 mobile broadband usb stick. It is recognised as a gsm-modem and shows up as such in the networkManager-plasmoid. I have set up the connection details for my ISP (O2), but I can't connect. When I click on the connection, "signal strength" is shown as well as "operator" (o2 - de). The "connection state" changes to "Preparing to connect", then "Setting network address". Then the modem vanishes and comes up again a few seconds later.

Here is the log (/var/log/messages):

Code:

It seems like there is a connection for about 5 seconds, then the modem hangs up and restarts .

The stick works fine with our windows netbook, so I don't think it is a hardware failure.

How do I get this working?

My system:
opensuse 11.4
kernel 2.6.39-30-desktop (2.6.38 gives the same error)
kde 4.6.3
plasmoid-networkmanagement 0.9.svn1192577-168.6

OpenSUSE Network :: Adsl Modem Acting As A Bridge To My Router Setup - Connection - Internet Went Slow ?

Jun 19, 2011

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 8.8.8.8 (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 8.8.8.8 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 !

OpenSUSE Network :: Hostname Not Saved In Router Table / Broadcast It To Entire Network?

Jun 13, 2010

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?

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 Network :: Network Manager Default Connection Can Handle Virtual Interfaces?

Jun 7, 2011

I've not found how to configure more than one ip address with network manager.Nor with kde nor with plasmoid network manager.I need several virtual ip addresses for eth0 when the "default" of eth0 is connected i.e. "Connected to Auto eth0" should initialize the virtual interfaces.I have not found no even how to configure the ip address.I think this will be used from ifup config in yast or not?There I have the virtual interfaces but they are not taken from network manager.And last but no least: Is it possible that when using network manager the eth0 is enabled even no user has logged in?

OpenSUSE Network :: No Network Connection After Firwall Settings Changed / Get It To Work?

Nov 17, 2010

I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.

As a consequence all network services are not working. I can't connect to any other machine nor to the internet.

I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.

Any suggestions how to make it work again? I'm using Suse 11.3.

OpenSUSE Network :: Configure A Connection With YAST As Well As With Network Manager?

Feb 1, 2010

Im new in this world of linux and suse. I have just installed the opensuse 11.2 in a Dell Inspiron 5160. Such laptop has a BCM4306 Wireless LAN controller. When I tried to configure a wlan connection, I found that the firmware was not installed. After looking in different forums, I installed the firmware b43. Now, my wlan card is abled to find the wireless of my router.

I have tried to configure a connection with YAST as well as with Network Manager, but both cases failled. Specifically, when I use Network manager, Im able to see in the applet my connection, how strong is the signal, but I see a yellow symbol (in one forum, such a box is shown with a green symbol).

I have check many time all about the secutity, encryption, and so one and all seems to be correct. But when I open the mozila firefox or the konqueror browser, no chance to surffer in internet. Now Im just a step to become crazy. The drivers are ok, the information about the router and the keys are ok, but in such a way, I am still harmloss.

OpenSUSE Network :: Network 11.3 - Connection Refused When Try To Connect To SSH From Another Machine

Sep 27, 2010

I 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.

OpenSUSE Network :: Network Connections Didn't Have Connection

Jan 14, 2011

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.

Networking :: Wireless Network Connection - Router - Won't Connect Fast - Automatic

May 26, 2009

My computer takes a while to connect to my Linksys N router.

It used to connect in a snap of your finger automatically.

Now it does not.

Yes I have tried manual configuration, and double checking the password, ssid, protocols, and security type.

WPA2 personal is the security type.

There are maybe 4 different ways I know how to connect. The most annoying thing is when this box pops up saying to type in a password for the network connection.. and keeps popping up even when everything is right.

All I need is a reliable, easy, and automatic program to connect me to the internet, maybe even before I log into my system.

Linux Ubuntu 8.04 LTS Desktop Edition is my system. Brilliant system.

OpenSUSE Network :: Set Connection With Network Manager?

Nov 27, 2010

with the ifup method everything works fine. But now I bought a wireless card, so I prefer to use the network manager to manage my connection. On my computer I need a static IP for wired connection, so I created a new wired connection and I called it "wired connection". But network manager always connect automatically to "Auto eth0" and I can't find how to modify this connection. Setting "wired connection" as default didn't change anything, probably becouse it need me to unlock the default wallet... Now, another problem, I really don't know why network manager applet doesn't appear on system tray, but I'm sure that I'm using it instead of the ifup method.

OpenSUSE Network :: Using A DNS Behind A Router?

I've set up a server using 11.3 and ISPConfig 2. The problem is that I barely understand DNS. So the question is - If I set up two domains through ISPConfig do I have the registrar have BOTH domains pointed to my IP address and then let my DNServer figure out where to send requests or do I have to have 2 different IP addresses?

OpenSUSE Network :: Nfs/Nis Using OS 11.3 Machine As Router

Dec 2, 2010

I had an OS 11.3 machine running as an Nis server with Nfs, also providing dns, squid, samba shares and running apache

Internet connection provided by a netgear router at 192.168.0.1, server at 192.168.0.2, clients at 192.168.0.3, 192.168.0.4, etc. The clients all being configured to use the server for dns the squid running on it for their proxy, logging on with Nis using the exported server's Nfs /home share as /home on the clients

Everything was setup through Yast with some conf file editing being done later for samba and apache and all working brilliantly

Until ...

I added another network card to the server machine and set it up as a router, where they will be placed once ready the router providing the internet connection doesn't have gigabit ethernet

So I figured if I had gigabit cards in the clients and a gigabit card in the server set up for the internal zone and providing routing, then the clients using it as their router the local stuff would be more responsive, especially as they are using an nfs share for /home

I set the clients up to use the server at 192.168.1.1 for their router and changing their own local ip addresses to suit, i.e. 192.168.1.2, 192.168.1.3 etc and rebooted

Nis and nfs were no longer working, so I logged on as the local user, ecky, who's home directory isn't in the nfs share but at /ecky, the internet connection worked fine and so did everything else, dns, proxy, etc

I tried changing the nfs share and nis server to the internal card's ip, 192.168.1.1 and that didn't work either

Samba shares work at both 192.168.0.2 and 192.168.1.1, so my problem is that nis logons and nfs mounts don't work from either address

I've tried to give as much info as possible on what I've done without being too confusing ... don't know whether I succeeded

Darned annoying cos it took me a day and a half to get the gigabit card to detect properly in one of the machines...

OpenSUSE Network :: Conected To Router But No Internet?

Sep 6, 2009

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

OpenSUSE Network :: 11.2 Acting As Router Firewall

Mar 29, 2010

switched recently to 11.2 and it works fine for me as workstation I want to set up a router separating a part of the network and also acting as a firewall/proxy... Configured 2 Ethernet Interfaces, checked Ip forwarding in Yast but it does not forward the packets from the "internal" to the "external" network. Hovewer after I set up my router as default for machines on internal network I can ping the external interface but no adress on external network (particularly the one of the default router) !!! From the router I can reach both networks and the net via default gateway on external. Tried to:

a) switch firewall completely off
b) iptables -P FORWARD ACCEPT
c) masquarading internal adresses to the external network

my interfaces configuration looks like:
eth0 Link encap:Ethernet HWaddr 00:13:D4:E3:A2:7B
inet addr:192.168.1.34 Bcast:192.168.1.255 Mask:255.255.255.0

OpenSUSE Network :: Setting Host Name On Router

Apr 8, 2010

I am running

Code:

On my laptop (HPDV7), using DHCP for network access, KDE4.

I use Network Manager to manage wired and wireless connectivity.

I also have Samba server running for connectivity to Windows machines.

My router runs DD-WRT.

How do I tell this HPDV7 system to propagate a Host Name up to the router?

In the DD-WRT status screen, I see Host Name as "*" associated with the assigned IP address.

I cannot, for example, ping my HPDV7 machine from my windows machine, I assume because the router (also providing DNS for my network) does not provide the name to address translation.

I CAN ping the IP address directly, and Samba connectivity from the Windows machine to HPDV7 works.
