OpenSUSE Network :: Using WiFi And Ethernet Connections
Feb 5, 2011
I've been searching for a couple of hours and have not found any threads that solve my situation... hope I'm not repeating something here.
Setup: Notebook with openSUSE 11.2 using KDE 4. Using Network Manager to manage network connection (although I've tried configuring this using ifup as well with no luck).
I need to be able to connect to client networks via a network cable (Ethernet) and connect to the internet via my MiFi 2200 Mobile WiFi. Both cards/connections are active with the following:
I have no problem mounting drives from the client's network. But, can not reach the internet. If I disconnect the ethernet cable, the browser will immediately connect to the internet and load web pages.
I'm assuming the ethernet connection is taking precedence over the wireless connection?
I can't imagine that there is not a way to set this up. If Windows can do it, I'm sure openSUSE can!
I often use an Ethernet cable to connect my computer to another computer for various purposes. But when I do that, I cannot use the internet even though I'm still connected to a WiFi access point. I'm presuming that's because openSUSE is trying to reach the internet through the Ethernet cable, which has precedence over WiFi.Is there a way to enable internet usage via WiFi while I'm connected to another computer over Ethernet?
My WiFi can connect to internet without any problem, until I plug my ethernet cable ...then I lose internet.
So the question is : how do I configure my ip/dns and stuff to still have internet when I'm plugged by cable at the same time! it was working on windows ;-)
I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.
I've been struggling with this a bit now, and I'm not sure what the problem is. I have a laptop with a BCM4401 Ethernet card as well as a BCM4311 Wireless card. The wireless card works great out of the box, I'm able to connect with it perfectly. The problem is the ethernet card. Here is the situation: The NetworkManager menu doesn't list "Wired Networks" at all (ie. it doesn't say "not managed", it just only lists Wireless networks) Going into Network Connections, there is an "Auto eth0" entry ifconfig shows eth0 (which I assume means NetworkManager isn't managing eth0) I have edited /etc/NetworkManager/nm-system-settings.conf to say managed=true I have edited /etc/network/interfaces to remove any mention of eth0 (all that's left is the "lo" lines) So I'm not sure why eth0 is still showing up when I run ifconfig, and why Network Manager is not managing it. Any ideas?
Edit: Not sure what I did but now ifconfig spits out this:
Code: eth0 Link encap:Ethernet HWaddr 00:1c:26:2c:60:75 inet addr:10.0.1.12 Bcast:10.0.1.255 Mask:255.255.255.0 inet6 addr: fe80::21c:26ff:fe2c:6075/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[Code]...
The MAC address of the "Auto eth0" entry is 00:1C:23:8F:D4:39, the same as the eth1 entry that ifconfig spits out.
I am basically wanting to use my Ubuntu 10.10 computer as a router. Note: Before you say just get a router please note that I am poor/cheap. I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.
DSL-->1sr Eth --> 2nd Eth (currently works) DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)
The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).
I have openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections. I want to play with my friends some lan games, but we are in different networks, so i want to create this gateway server so we can connect with VPN clients to this server and play freely.
Does anyone know how to permanently enable X connections from all machines on my local network. I keep having to enter 'xhost +' to allow X connections.
I first tried an upgrade from 11.3 to 11.4 and lost Internet Access, so i re-loaded 11.4 from scratch on clean partitions.
I am connected to my wireless WPA2/PSK connection, have an IP, am able to see the network.
I turned off and disabled the SUSE firewall.
I tried setting Firefox proxy settings to auto and to none, i dont use proxy.
I am currently posting this through an SSH connection to my 11.1 server from the new install of 11.4 on a Dell latitude D600 laptop (not using the on-board Broadcomm that is an issue for a later date).
I had a google of this but can't find anything useful. I use networkmanager to configure my wireless card. Currently this only works when I'm logged in to KDE. If I log out the system loses the network connection. Is there a way to make it persistent using NetworkManager?
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.
network manager isnt showing any network interfaces. ifconfig shows wlan0 and eth0 and internet is working. how can i get network manager to manage those connections?
I remember when using openSUSE 11.3 with KDE 4.5, the network connections started to show the last date used for my "NIC".I am using the plasmoid-networkmanagement plasmoid and KNemo.After I downloaded and installed openSUSE 11.4 64-bit, the network connection no longer shows the last date used. I have set up my card via Yast and Iam connected directly to the Internet. No proxy.To find where this is located, navigate to:Configure Desktop --> Network Settings --> Network Connections --> Wired tab.
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?
First a warning that I'm so clueless it hurts. Initially I entered the Linux world as a solution to my blue screening Alienware Aurora desktop (which later fried anyway ironically enough). I decided to give up on Windows for everyday use cause you can't strangle an operating system. My first and there after Linux experiences have been fantastic. Internet works without prompting through various distributions of Ubuntu, Mint, and KDE with the exception of enlightenment.
But now I come to openSUSE 11.4 and as my title suggests I'm having a hard time connecting to the internet. I've got a wireless card and router and all that jazz but I can't even select the options for wired or wireless connections under Network Connections in the Network Management Settings. Everything is greyed out except for VPN. I even have the desktop wired to the router and it still is not giving me any indication that it will connect.
I'm wary of trying to enter ip addresses and things of the like because I honestly don't know what i'm doing here.
My router is a Netgear N150 Wireless WNR1000 and in the Kinfocenter under Device Viewer I found my wireless card to be a RaLink RT2561/RT61 802.11 g PCI and my wired device thingy to be an Intel 82540EM Gigabit Ethernet Controller.
I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.
does opensuse 11.2 come with IPv6 enabled by default? where in the gnome gui can i access these settings?
Edit-i went into the gnome network manager applet and i cant find any IPv6 settings for any of my used connections-ethernet, wireless and VPN connections all seem to only IPv4. Can anyone else confirm that opensuse 11.2 uses only IPv4 on its network connections?
I'm running suse 11.1 which is configured as a router. Configured are two DSL connections with static IP's and one LAN connection (3 NIC's all together).
Problem: suse firewall will only port forward connections from one of the DSL connections and not the other.
Because I'm running two DSL connections is there something special I have to turn on/enable on the firewall?
My question is simple - is there any linux app or applet which is able to show (monitor) incoming and outgoing connections assuming it's a direct internet access? I was using a firewall on a system off Redmont which was able to show every connection, listening ports of services if some were opened etc.
My home computer has 11.3 and SuSEfirewall enabled. It connects to the net over the wireless and SuSEfirewall has this connection in the external zone.
I can successfully ssh into this computer from remote (the work computer) but none of the ssh port-forwarded connections work. I'm trying to tunnel VNC over ssh. I also tried setting http on the home computer to serve pages on a high-numbered port (8090) and tunnelling that but it also didn't work - proving that it's not a VNC problem.
Here are the relevant messages from the firewall logs on the home machine:
Code:
I don't understand why this isn't working now, I had the same setup on 11.2 and it worked fine.
The 95.91.92.92 is the public IP address of my home router, I don't understand why a connection would appear to be coming from there when I use ssh-tunnelling?
My ISP has for a long time had a broken forward/reverese DNS so that my ADSL connection with static IP address resolves to a completely different IP address on a reverse query. This has not been a problem until I upgraded a remote server from 10.3 to 11.3 last weekend and now ssh connections from my ADSL connection to it using public/private keys are being rejected with the following message in /var/log/messages (IP addresses changed): Aug 10 12:00:32 penguin1 sshd[1270]: Address 83.175.246.243 maps to 83-175-246-243.static.dsl.aupex.com, but this does not map back to the address - Possible Break in Attempt!
But if I log in interactively with username & password, the connection succeeds. I've changed the StrictModes setting in sshd_config to 'no' but this hasn't resolved the problem. Obviously something in 11.3 is being stricter about this IP mismatch than it was in 10.2 (and no, the server is not using a firewall). There must be something I can change to make sshd more permissive? I've tried before to get my ISP to fix their problem but no luck. This needs to be sorted as a server at my home (which does not run SuSE) retrieves backups from the remote OpenSuSE 11.3 server every night using scp and these are now failing.
Every single time I enter the network manager to edit connections is crashes on exit. I am running opensuse on an Asus eee PC 1000HE with an Atheros network card. The crash report follows :
As an extra point. I wish I could disconnect individual networks instead of just disabling networking to disconnect. I think the newer version of the network manager does this.
I have just switched over from Ubuntu. My PC with Ubuntu connected to the ethernet fine, but now the internet is not found at all. Can someone tell me what sort of things I need to do to get my internet up?
I have troubels with internet, on different Linux x64 systems on my laptop(Lenovo ThinkPad sl510), but if I load WindowsPE all is OK ( what coud it be? where to search?There is an hardwere firewall/nat/gateway in my local network, it allows only connections to dst ports tcp 80 (http), udp 53 (dns) and no frags, no icmp, deny in and etc. But Windows Internet (the same Firefox) works fine , and under Linux sites doesn't loding full or "connetion timed out"...But if I have can start downloading any file it would be downloaded full (I have downloaded DVD iso of SuSe)Dns throu nslookup responce not evry time...Decreasing of MTU to 1372 didn't help (( Deactivating ip v6 also....What coud it be? What is different betwin Windows and Linux in DNS clients is any alternative dns client in SuSe? Is the trouble only in DNS?
I have a A7V8X-X motherboard with VT6102 [Rhine-II] on board network device. Internet connections work fine for long time on openSuse 10.3, 11.1 11.2 and 11.3. But since a few weeks ago, internet connections began to fail: several times when I want to open any Internet site with Firefox, it answers:
I want to share my WiFi internet connection over LAN, so I'm trying to set up IP forwarding. An old tutorial tells me to go to Network Settings in YaST to do this, but that applet says that NetworkManager is now handling all of that stuff.How do I enable IP forwarding while NetworkManager handles my internet connections?
I have a workstation with the two ethernet ports (eth0, eth1), the problem is that i cannot run with both ports up and running. I can run with either one of them, but not both.
Below is the contents of my /etc/network/interfaces file:
