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.
I recently setup a new SUSE box for the purposes of acting as an ftp/sftp server. It's currently setup to run ProFTPD 1.3.3.rc3 and mod_sftp/0.9.7. The server has two internal network interfaces eth0 and eth1. eth0 is purely for internal use to accept ftp and ssh. eth1 is outward facing and receives connections from the WAN via SFTP over port 22. The problem I am facing is that after half hour to an hour eth1 stops accepting connections whenever there is no SSH connection present on eth0. I can't figure out why this is happening.
ProFTPD is setup as follows: SocketBindTight directive is on, default server and port are commented out.
[code]...
When the external interface is unreachable the proftpd and proftpd-sftp logs show no record of any connection attempt. I have noticed however if I leave eth0 down eth1 stays contactable without problem. Can anyone give me some pointers on what I can check to find out why this may be happening.
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?
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.
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.
When I firsts installed Ubuntu 10.04, and tried to hook it up to my wireless network it noticed my connection and accepted my password, but did not connect. My wireless card doesn't have linux drivers installed. I found the correct drivers, but I am unsure of the correct way to install them in Windows so they work in Ubuntu. I am currently dual booting Windows 7 and Ubuntu.
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?
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.
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.
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.
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.
I'm new in SUSE 11.4. My problem is: I'm using Alfa AWUS036H card. It's recognised and I can establish connection to my network, but cant get to Internet. I can't surf the web cos Firefox tell me that connection is timed out. Now I'm confused why I can't surf the web even if I'm connected. Also, I trayed to instal linux drivers for this card folloving Ubuntu "how to" and it just dont work.
I installed openSUSE today using a network installer cd, opting for the Xfce environment. Everything went smooth with the installer, but I have some issues with the network. After the fresh install, nm-applet did not start. I got the following error:
Code: nm-applet ** Message: applet now removed from the notification area ** Message: applet now embedded in the notification area ** (nm-applet:14981): WARNING **: Fallback icon 'gtk-dialog-error' missing: (0) Icon 'gtk-dialog-error' not present in theme ** ERROR:applet.c:2800:nma_icons_reload: assertion failed: (applet->fallback_icon) Aborted I don't know if the problem was with the applet or with the daemon. Fortunately I used Archlinux for a quite long time and I know how to connect to WPA2 encrypted wireless network from command line, so I was able to connect to the internet and do an upgrade - everything went just smooth and fine again.
After the update and restart, I found the nm-applet icon in the system tray. And here comes the second problem: I can connect with the nm-applet, but the connection does lasts only for about 10 seconds. So practically I can't use the net this way either. Ok, no problem, I fired up Yast, disabled the networkmanager and choose to start my network with the traditional method. I entered the required stuff from my wireless card ( ESSID and passwd ), set to activate at boot time and reboot.....
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.
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.
I installed a simple VPN pptp. Works fine to connect to the linux server. However I would like to connect my other linux-server and (more important) my old Novell 6.0 server. Anyone have an idear what I need to change?
I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
I have my box setup as a router/NAT with two different network cards. One for external connection(connected to the Cable Modem) one for internal connection(used for internal DHCP). It works perfectly when I manually activate the two interfaces after booting(both interfaces always show up as inactive after booting), then the DHCP server and firewall. I am confused, however, by which program has control of these interfaces.
First, there is the Network Configuration (System->Administration->Network), which is where I manually start the interfaces after rebooting. Both interfaces are set to "Activate when computer starts" in here.
Second, Network Device control(System->Administration->Network Device Control), which looks to be almost the same thing as the above.
Third, the NetworkManager applet(on the top bar) - both devices show up as unmanaged when I left click on this, but if I set "Controlled by Network Manager" in the "Network configuration" window(number one above), It still does not work. Can I get rid of two of these programs, or is there some way to edit the startup scripts to start my ethernet cards before the dhcp server/firewall(which is shorewall BTW)?
I am trying to Setup citrix ICA client 9 on Ubuntu 9.04 Server. I installed it very easily and I am not getting any lib error also. But when I try to connect to the citrix server, it fails with a pop up saying "Error in Network Connection Network or Dialup connection may be preventing ......" This is driving me crazy from 3 days. My project is to check the feasiblity of a Linux desktop
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'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'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?
