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 Wireless :: Network Settings And Usb-wlan-card Didn't Work

May 8, 2010

i installed suse (KDE) on my old notebook and now I'm trying to get the wlan to connect to our router and can't figure out how to get it to work. My card seems to work, the network manager even finds the router, but i just cant get a connection. I followed the steps of the "Getting Your Wireless to Work" thread and these are the results:

[Code]....

- i messed around a bit with the network settings and might have cluelessly broken something (or broken it more)

- i tried a usb-wlan-card as an alternative, which didn't work either, but could possibly have messed things up even more.

OpenSUSE Network :: Wi-Fi Connection Does Not Work After Boot

Apr 19, 2011

I have a router working as an access point for Internet access. It is used by sveral computers. Wi-Fi connection to Internet through this router does not work after boot on openSUSE 11.4.The cannection becomes established, shows IP address, access point MAC address,the signal level is high. But Internet is unaccessible with traceroute returns"the host is unreachable" message.

If to disable the automatic start of the interface and start it manually with ifup wlan0, nothing changes: the interface still does not work after first start.This is very annoying because this laptop is use by a girl who cannot restart interface. She says she cannot do anything with it.

OpenSUSE Network :: Unable To Ping The Default Gateway When Using Custom Settings - Unreachable Network

Jul 17, 2011

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've updated a desktop from 11.1 to 11.2 with the NET CD. After completion everything worked fine, though I have some issues with the NIC. been looking on the net and the provided solutions haven't been able to resolve the matter. After reboot I don't get an IP address, I go into Yast2 and network settings displays:

I have to delete the unknown device everytime after a reboot in order to get a new IP address. After that all works as it is suppsed to. I've been looking into the /etc/udev/rules.d/70-persistent-net.rules and deleted all that was in there,

OpenSUSE Network :: Two Network Cards With Different Settings For Internet Access

Feb 9, 2010

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.

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 :: 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 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 :: 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.

OpenSUSE Network :: Network - Browsing The Internet With Domain Names Does Not Work

Jun 25, 2010

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.

OpenSUSE :: Has Network Manager Changed

Jul 30, 2010

Some time ago I asked about SCPM in 11.3. Turns out it was removed, and the suggestion is made to use Network Manager.

Some of us are not excited about this, because despite the name Network Manager did not manage networks - it managed connections. Those of us who presently use SCPM to choose which NFS fstab entries, which printer, etc

When changing connections want to know whether indeed Network Manager can indeed now manage networks instead of just connections.

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 :: Literally ODD - Network Services Don't Work Every Second Boot?

Sep 14, 2010

I have an OpenSuSE 11.1 in vmWare ESX and every other boot I can't access any running network services (ssh, webmin, qmail, mysql, ...) from outside. I just need to login, reboot and voila - network services are working.I gradually updated to 11.2 and 11.3 by following the wiki with success but this problem remained. So I reverted to snapshot of 11.1 and now I would like to identify and solve the problem here first.I also looked at /var/log/messages /var/log/boot.msg /var/log/lastlog but can't find anything usefull. I will now compare those files from the working and non-working boot but meanwhile someone already has an idea or experience what could be wrong?

OpenSUSE Network :: 11.3 - No Network Connectivity - Audio To Work On Skype

After installing OpenSUSE 11.3 (64-bit), I do not have network connectivity (Ethernet or Wireless)? Neither adapter can be detected? I thought the install would be fairly straightforward as Kubuntu 64-bit detected all the hardware.

It can retrieve some files, but while getting others it fails. Furthermore, I can't establish a connection with the timeserver in the YaST -> NTP configuration module.

My question is if there have been changes from this version to 11.3 regarding the Proxy settings.
