OpenSUSE Network :: Static IP For Bridged Connection ?
Aug 11, 2011
I have virtual box installed which automatically installed bridges for my network adapters. This has always worked fine. I'm attempting to set up a static IP for this machine now. I use NetworkManager, and the physical connection (eth0) is set to static IP of 0.0.0.0, and the bridge (br0) attached to eth0 was set to DHCP. I changed br0 to my desired static IP and lost net connectivity (I'm talking about the host, not the virtual machine - I'll get the host working first). Re-enabling DHCP restores connectivity. So I don't know what the problem is, but I am unable to assign a static IP to the bridged connection. Do I have to do this differently? Do I need to remove the bridge so I am using just eth0 again, assign the static IP to eth0, and then re-install the bridge? I haven't tried that yet because a) I don't know how to remove & reinstall the bridge, because it was done automatically by Virtual Box installation, and b) I could probably do that if I had the time figure it out but right now I don't.
I set up a static IP on wlan0 on another machine using Network Manager and it works fine. That machine also has Virtual Box installed but for some reason doesn't have the bridged connections. (Perhaps because it runs Ubuntu, not OpenSUSE, if that makes any difference)

I virtualised backtrack on windows 7, and set up the network connection to bridged mode, but my networking still fails.
dhclient eth0, outputs many DHCPDISCOVER but no DHCP offers.

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)
But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)
The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.
Is there a way to have both of these pieces of functionality?
I am using FC14

Newbie Question: How do I setup networking on openSuSE 11.4 on an HP Proliant DL385 G7 with 4 NICs to host Windows 2008 R2 on Xen? I've installed openSuSE 11.4 with all the patches (and most of the server patterns - Mail and News, LAMP, LDAP, Samba, etc.), and I've installed Windows 2008 R2 in a Xen virtual machine. I'm having problems configuring the 4 NICs eth0, eth1, eth2, eth3 are "bound" without an ip_address as br0
eth0 connects to my ISP - currently through a private LAN - It connects directly to the router with static IP 192.168.0.105 Eventually, one of the other NICs will serve ip_addresses via DHCP to a separate LAN (for use in an office setting), and eth0 will be set with a static IP from the ISP That means, eth0 will be static to the ISP, and the other NICs will attach to a switch serving private ip_addresses in the 192.168.0.xxx range.
Currently, I have br0 unconfigured and eth0 static. I have configured eth0 in the External Zone and br0 in the Internal Zone in the firewall, and all the correct ports are opened (afaik) I have enabled masquerading. Hostname, Domain (workgroup), DNS Server addresses and IPv4 Gateway are configured.
Windows 2008 R2 (Guest VM in Xen) "sees" the other machines on the network, and "browses" the internet, although it will not download patches except intermittently. I have not tried connecting to it from the LAN Eventually, I wish to run Windows Terminal Server. openSuSE cannot "browse" the internet, though it initially did. What am I missing? I "think" I need routing or NAT, or I may have my bridge setup incorrectly, although I've tried almost every combination. Google says Xen should be setup with either NAT or a Bridged Network.
Output of ifconfig:
br0 Link encap:Ethernet HWaddr 3C:4A:92:76:B8:F2
inet6 addr: fe80::3e4a:92ff:fe76:b8f2/64 Scope:Link

Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

I'd like to have a set up where my Ethernet card has a static IP set up but my WiFi card doesn't.Currently I have a profile for this set up in Network Manager, however on boot up and every time I replug the cable Network Manager chooses the default "auto eth1" profile. I manually have tochoose my own profile for the Ethernet card every time. How can I make it default??I know the workaround would be to use ifup but then I lose the ability to quickly change access points for my WiFi card so that's not a solution for me

New SUSE 11.3 install connects to network/internet etc OK with DHCP-assigned IP address. When I switch to static IP, I can no longer ping internal network, or anything else. This works OK with SUSE 11.2 on same hardware and (as far as I can see) same setup. Some diagnostics are shown below.
Firewall
Disabling the firewall makes no difference.
Not using a network manager (can't see how to assign fixed address if I do - all greyed out).
ifup eth0:
eth0 device: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
SuSEfirewall2: Warning: no default firewall zone defined, assuming 'ext'
(not sure why the warning - eth0 is assigned to external in the firewall setup).

I posted this in the Networking section, but should probably be over here. Couldn't move it. I have a transparent proxy in place. I have Webmin installed on the server. Is there an app that can monitor bandwidth in real time? Also run reports? I have SARG installed, but seems to only monitor HTTP traffic, I need to monitor all traffic. I have a bridged connection, but monitoring the outside interface is fine too.

We're trying to replicate something that Windows servers can do. Basically on a Windows box, you can give it a static IP address, but there is an option to have it update the DNS server with it's IP and hostname. We are trying to do this on SUSE 11.I know I can get this function to work on SUSE if the box is set up as with DHCP. What we're having difficulty is when the server is set up as a Static IP to get it to update the DNS server

Recently our sys administrator decided to go to static IPs from the earlier assigned dynamic ones. This has created some havoc in my open suse 11 and I do not have access to network. I tried using the YAST network configuration manager, after everything is done it shows 'network wired' but unable to ping.

how I can define a local static IP address (so that I can run a web server off of the same IP, rather than letting my router DHCP it)?I've tried doing the YaST->Network Devices->Network Settings->Traditional Method with ifup->Set NIC to desired IP->Set Default Gateway to router address method, and afterwards I can't even get into my router anymore (not even responding to ping).

I'm maintaining a very modest network at home, with OpenSUSE as OS on the server. I got the DHCP and routing working by following the instructions in the wiki. However, every time I run dhclient on the server/router, it appears my own DHCP server assigns an address to the internal network card despite the fact I specifically assigned it to be static using Yast. The situation resolves itself when I restart the network services with the command /etc/init.d/network restart. Otherwise no problem, but it also seems the internal network card gets a "new" IP from my server every time the external card requests one from the ISP. This is more of an issue.

I think that i lost my memory, because i completely forgot how to accomplish this.
I have a WEB/MAIL server configured to work on a static IP address, lets say 200.11.22.33.
Now I wanna point a domain to that server to get the services up and running, lets say mydom.com ...
The static IP Address is assigned by my Internet Provider.
I'm lost in the part of connecting the domain with the server.
I have the domain DNS pointing to the ISP name servers, but I don't remember if this is the correct way, or if I have to setup my own DNS server.

I have a problem with tightvnc, when I set up a dinamic ip with networkmanager it works fine but if I set up a static address connection it display an error "You have been unexpectedly disconnected from 'hometsa-comp'. Would you like to reconnect?"
"Couldn't convert 'hometsa-comp' to host address" I have setup the ip address, netmask, gateway and dns server in the network manager static address, it works when I setup the vnc connection using ip address instead of hostnames.

I would like to set-up a pretty fast a running apache. I would like to use him so to launch a pretty small web site of 10 static html pages. At this time there is no security concerns (even though I want to do it right) , because the computer has not even ethernet cable. I have some experience, 8 years ago I Was setting up virtual hosts in fedora, so this process is not a blackbox for me.

I can make a connection to the vpn server, the connection starts, but nothing happens! My IP address remains the same as previous! There is nothing added to my Knetworkmanager, I'm a beginner I should use a pcf file for my vpn connection. I use it properly, I'm sure because the connection starts and an icon is added to my panel and remains until I disconnect.
I checked it via ifconfig -a, the last part (which is for vpn) is:
Code:
tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

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.
