OpenSUSE Network :: Firewall Status Of Eth0 And Wlan During And After Installation?
Apr 22, 2010
I get connected to the internet via a router. The router dials to my provider and is connected to my computers via LAN and WLAN (mostly WLAN, see below). A few days ago I installed Suse11.2 to an old laptop (connected both ways: ethernet with wire and wireless ethernet).
The access to the online repositories worked only after I added the LAN-Adapter (Eth0) to the Demilitarised Zone of the firewall (I did also with the WLAN Adapter).
1. Is this normal?
2. Should I add the network devices now to an other zone?
I want to update my main laptop now from openSuse11.1 to 11.2 via new installation (from DVD) and make this installation right.
Or should I install only the data on the DVD and update after the installation via Yast?
(My main laptop has also an loose contact at the ethernet adapter.)
Greetings pistazienfresser
Now I am using (on my main laptop = Samsung X20) openSuse 11.1 and Gnome 2.24.1 (mostly, 1 account is using KDE) and Kernel Linux 2.6.27.45-01.1-pae. "/home" is on an separated partition (as part of an extended partition). I have also 2 NTFS partitions for Windows XP (System and Data), and a FAT, a root (/) and a swarp partition. My router is a AVM fritzbox 7270 (firewall should be included).

I tryed to setup a second IP address with yast on a openSUSE 11.2 on eth0 as eth0:2nd but with a different firewall zone. But SUSE firewall just see eth0.
I want to define with services are available on with IP address. Also with custom rules I can't specify a destination IP.
So now can I do this with yast? Or have I todo this manually without SUSE firewall?

There is no wlan0 interface when trying to run FRITZ!WLAN USB Stick N 2.4 on OpenSuSE 11.2, though it works fine on Fedora 11 and Mandriva Spring 2009.1. All 64bit. Contrary to Fedora and Mandriva, there is no need to compile the compat-wireless module ar9170usb for OpenSuSE 11.2 because the kernel is very recent and includes this driver. Kernel: 2.6.31.5-0.1-desktop The /var/log/messages gives this after I put the stick in the PC. At first it is seen as a mass storage device:
Nov 27 22:00:24 linux-3mwa kernel: [ 73.420755] usb 1-5.1: new high speed USB device using ehci_hcd and address 4

I suspect this is an initial configuration bug. All firewall logs seem to be going to all
three files. That causes a lot of clutter in the log files, and makes it difficult to see whether there are any serious problems being logged.

Am all of 2 days old on Opensuse 11.0 having just installed it on my old PC. All my experience has been with XP/Vista and Macs and it took some courage to finally try this out. My Belkin F5D9050 wireless(g+ MIMO) usb network card is recognised in yast but does not connect to the internet. On reading through forums I understand that this adaptor uses RAlinks RT73 chipset and support for should already be available in the OS. Is this correct ? If not, where do I get the driver for this and how do I install this. As per the Belkin site, Opensuse driver support isnt listed. Am struggling due to the unfamiliar environment and am not aware of terminal commands.

Installed a TP-Link TG-3269 Gigabit card in a machine running OS 11.3 32 bit, when I go into Yast, Network Devices, Network to try configuring the card I get this errormsg: Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. Couldn't find any mention of the card in dmesg's output, (though the 8139 onboard card is in there) there is some stuff about pci host bridge but I don't know whether they would be relevant or not
The chip on the card says it's rtl8169sc but lspci lists it as being 00:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8369 (rev 10) Done some googling and there don't seem be any drivers for a Realtek 8639 and it returns no matches from a search on realtek's site, but there is a driver there for rtl8169sc chips, which I downloaded and installed, no errors when installing it Even after a reboot I still get the same error in Yast's Network Settings screen, lspci still lists it as 8369 and the device isn't listed at all if I run ifconfig

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?

I'm new to this forum site and I was wondering how can I bridge a network between the eth0 and wlan0 connections?my eth0 NIC is a RealTek RTL8111B 10/100/1000 Ethernet Card (OnBoard) and my wlan0 NIC is a RealTek RTL8187B 802.11b/g WiFi USB Adapter Card.Are there any utilities, such as bridge-utils that I can use, except for Firestarter since Firestarter states that the eth0 connection is not established, or do I right-click on the network icon and select Edit Connections and go to Auto eth0 and under the IPv4 Address setting and select Shared to other computers and run a live connection there?The main reason is that I need an Internet connection for my Xbox 360, which is connected to my Linksys WRT54G 802.11b/g Wireless Router, that has DD-WRT firmware installed and 4 WiFi hotspots for any wireless device, such as my PSP, DS, DS Lite, Wii, Laptop(s), my brother's PC (needs a WiFi card), and my dad's PC (needs either a WiFi card or an Internet connection from my brother's computer to my dad's PC)
Here are my Computer Specs:

I have set at static ip on eth0:
In have configured the /etc/network/interfaces as:
Code:
auto lo
iface lo inet loopback
auto eth0
[Code]....
However, I experience a slow Internet connection when using wlan.
Is this a routing issue, or have I configured the /etc/network/interfaces config file wrong?
I use Ubuntu 10.04, 2.6.32-22-generic

I can't get my wlan running, although it already worked on my notebook (Dell Inspiron 1545) with opensuse 11.1. Then I installed debian and, I don't know how, it changed my kernel in grub from .pae to .debug (renameing in grub didn't help)
According to the messages scanning fails
My wlan-controller is:
Router is avm Fritz!Box and is working fine with other notebooks and the lan of the Dell
I loaded down and installed the driver from Bradcom (hybrid-portsrc-x86_32-v5.10.91.9.3.tar.gz)
dmesg came up with a failure: not ipv6 server found - so I deactivated it
Below find further info:

I can't get WLAN up on my Dell Mini 10v (BCM 4312)/openSUSE 11.3/LXDE. And yes, I have thoroughly read iwfingers's 'Getting your Wireless to Work'. After installing openSUSE 11.3 ifconfig can see eth0, l0 and wlan0. No WLAN running. dsmesq|grep firmware prompts me to '/usr/sbin/install_bcm43xx_firmware"
After having done that and reboot ifconfig can only see eth0 and l0. Installing broadcom-wl-5.60.48.36-7.pm.16.4.i586.rpm broadcom-wl-kmp-default-5.60.48.36_k2.6.34.0_12-7.pm.16.4.i586.rpm (current ones from Packman) does, Shall I try to install the drivers without installing the firmware first?
Why does broadcom-wl-kmp-default-5.60.48.36_k2.6.34.0_12-7.pm.16.4.i586.rpm install a new default kernel? Ubuntu Netbook Remix 9.04 had no problems with WLAN.

I'm unable to get into my university's WLAN network. LAN works just fine, but sometimes it's quite convenient to be able to access stuff wirelessly. It doesn't seem to be a hardware problem, because if I configure my computer according to our computer department's instructions it works fine with Ubuntu (currently I carry around a stick to get into the Internet when I really need it and don't have a cable). Some info:
My device:
Broadcom WLAN controller on a Lenovo G560
My system:
OpenSUSE 11.3 64-bit
The drivers are installed, I can get into normal private networks, but have never managed to get into the university network except for with Ubuntu.
The university instructions tell me to use the following settings:
Security: WPA Enterprise
Authentification: TTLS
Inner Authentification: PAP
Username: My username
Password: Password
CA Certificate: Deutsche_Telekom_Root_CA_2.pem
In the KDE instructions, they tell you to write "anonymous" into the anonymous identity field, but in the GNOME instructions it says to leave it blank. In Ubuntu, I leave it blank and it works.
I've got the recommended settings, which also work in GNOME.
I'd ask the tech support here, but I am the tech support We've got it working with other systems, like I said, but not with SUSE, and I'm a SUSE fan.

I would like to know if it's possible to create a continual log for a network interface card's status. That is whether it's up or down and time and date stamped if possible.I'm wondering if there is a cli command that exists to do this I've looked at "ethtool" but this only sets the parameters of the nic.Also looked at the log files that I could find /dev/log var/log, but there is no mention of a status for eth0.

I have searched around a bit for a knetwork manager issue I am having on my opensuse 11.2 32 bit install. My wireless card is an 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) I am currently using the Broadcom wl driver
I am on the Internet with this machine as I am typing using the older "ifup" method. I am having great difficulty connecting to the Internet when I use knetwork manger though. The strange part is when I am connected to my router with knetwork manager, I can log into my Router, but I can not get to any web-page/ping any outside address.
so far the best (I was able to locate) advice I was able to get is located in this post. < Broadcom wireless, partchy internet - openSUSE Forums > following a posted how to to disable IPV6 (I suspect this may be the issue??), I was unable to locate modprobe.conf, or modprobe.conf.local, even after I updated via updatdb. I gave a shot at entering in "disable_ipv6=1" into "menu.lst". However, this did not solve my issue with knetwork manager. If my network information is needed when I am "connected" utilizing knetwork manager

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.

I just installed a fresh copy of 11.2 I use networkmanager and the cisco vpn plugin (not the cisco client). I create a vpn profile and connect to it. The icon shows a connection has been established, but I have no network connectivity. In the /var/log/NetworkManager file, I see this
Code:
Dec 19 13:28:08 TonyLaptop nm-dispatcher.action: Script '/etc/NetworkManager/dispatcher.d/netcontrol_services' exited with error status 127.
When I sudo vpnc and connect that way, it works fine, it connects and I can pass traffic.

I am trying to add a custom allow rule in the firewall for a range of IPs from 74.201.102.0 - 74.201.103.255, what exactly am I supposed to enter in the source box? I believe I have to add two separate rules for 102 and 103, and I put /24 at the end of both, is this correct to get the whole range of IPs?

1. Under openSUSE 11.2, I allowed printer sharing through CUPS by setting the Firewall to Allow Services of CUPS in the External Zone section. I don't see the CUPS option in the Allow Services of the Firewall under 11.4, any zone. Is my system missing something?2. If I turn off the Firewall, the client computer can see the printers, even get the broadcasted names. If I put port 631 in TCP of the Advanced setting of the External Zone, the client computer can see the printer too, but I know I read somewhere that putting 631 in the External Zone is basically allowing printer requests from the entire internet.

I tried to update my fully-working 64-bit 11.1 system to 11.2. I used the network install and chose the Update option. It took a few hours so I didn't sit through the entire installation but when I returned the 11.2 login screen was displayed. Having logged in, however, I found that I couldn't access the network.The boot log showed that network had failed to start. "ifconfig" lists only the "lo" interface. "ifstatus eth0" returns "Interface eth0 is not available"
Network Settings in YaST lists 2 entries in the Overview tab. The first entry has Name:"NetXtreme BCM5755 Gigabit Ethernet PCI Express" and IP Address: "Not configured".The detail pane for this entry shows "NetXtreme BCM5755 Gigabit Ethernet PCI Express (Not connected) BusID:0000:3f00.0 Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details". The Edit and Delete buttons are both disabled for this entry.
The second entry has exactly the same name as the first with the IP Address listed as "DHCP4". I assume this was the entry that was carried over from the 11.1 system. The detail pane for this entry shows "NetXtreme BCM5755 Gigabit Ethernet PCI Express (No hwinfo) Device Name: eth0. Started automatically at boot. IP address assigned using DHCP4". The Edit and Delete buttons are both enabled for this entry.lspci reports "3f:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 02)"
lsmod lists only "edd", "loop", "sr_mod", "sg", "cdrom" and "dm_mod".
The files in /etc/sysconfig/network/ are "if-down.d/", "if-up.d/", "providers/", "scripts/", "config", "dhcp", "ifcfg-eth0", "ifcfg-lo", "ifcfg.template", "ifroute-lo",
