OpenSUSE Network :: Setup Xen Virtual Nodes We Encountered One With The Network?
Jan 26, 2010
while trying to set up Xen Virtual Nodes we encountered one issue with the network (which is why it is posted here On the DomU the interface is provided by a bonding -bond0- of three NICS. Now the Xen network script a) does not take this bonding b) destroyes even this bonding From a number of posts I assume I have to configure this by hand, correct? Is there an instruction how to do this? Simply create a bridge on top of bond0??

I recently encountered an error with pppd on both openSUSE 11.2 and 11.3. I use umtsmon (which uses pppd) to connect to the internet with my 3G device. Yesterday for some reason it just plainly refused to connect to the internet. I have been using the same configuration for almost a year now without any issues. I tried it on 4 different computers running 11.2 and 11.3 and all of them failed. Thinking that it is the hardware I borrowed a windows laptop and tested it on that, only to find that it works flawlessly. On my network server I sometimes use the device as a backup and activate it with "ifup modem0", for some reason this also now fails.
After doing some troubleshooting I managed to extract the following from pppd.
Running it with my user account:
pppd options in effect:
I have no idea why pppd would break all of a sudden but I expect it might have been an update that broke it since I have automated updates on all of my systems.

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.

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 would like to use zypper to update openSUSE 11.2 through the Virtual Terminals (tty1 thro' tty6).
Network Interface is wlan0 (Wireless LAN, home network through a Router) that requires a password using WPA2.
My question is how to start wlan0 through the command-line ?

I just intalled OpenSuse 11.2 on VmWare Server 2.0.2, the network is configured as Bridged and is sucefully configured a fixed IP in my network. Ok... The problem is... I can ping / trace all addresses from OpenSuse console. But I Can't wget all of them... It's a random thing. the same address that trace's ok, don't work for HTTP.

Recently loaded 11.3 onto a virtual machine, however none of the network settings will allow me to connect to the internet. First time Ive had this happen, other distro's Ive experimented with connected with no problems. I recall seeing a similar topic some time ago (dont remember if it was here or another forum), but at the time, there had been no fix. Anyone know if this has been fixed?

I am trying for the last many days to setup my opensuse 10.3 as Samba PDC Server according to the URL mentioned below, but in vain:How to setup SUSE 10.3 as Samba PDC - openSUSE When ever I try to join a Windows XP machine to the domain setup on Opensuse, I get the error:'The following error occured while attempting to join the domain. The network path was not found'. What could be the reason for this error despite of the fact the I am able to ping the FQDN of the PDC from the XP machine, but the XP machine simply denies to join the domain because of the above mentioned error.

I have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?

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

I've just installed openSUSE 11.2, one problem is suse didn't find an internet connection when suse performed the ..."automatic system configuration. This routine attempts to configure your network and Internet access and sets up your hardware"... Where can I manually configure the network. I'm in the network folder now no luck. I've been using every documentation I could find Novell Documentation and DVD installation/11.2 - openSUSE Network Status: Unknown network status

I am new to networking and trying to setup my own local area network using virtual box machines. I have installed BIND 9.7.3 using yum in Fedora (dns server) and created all necessary .conf and zone fil es. I am successfully able to resolve domain names on this host machine (dns server). for example dig @dns.domain.lan client1.domain.lan correctly resolves domain name.

I am unable to do my network setup. I have a lan connection. I used to easily setup it in windows xp in network connections > internet protocol > properties. But I do not understand anything in linux. I have installed latest version of open suse 11.1 and KDE environment. Secondly I am unable to play mp3 files on it and I do not hear any sound at startup too. I *945* motherboard with a inbuilt realtek lancard and it is working fine on windows.

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?

Having made the transition from a certain widely used operating system to linux, suse 11.2, x64, successfully and pleasantly we are still left with a few problems.One of these is a few applications i have to use which run only in that old OS. ?To that end I have installed VirtualBox and got them to run with one glitch. I cannot print from VBox to my HP LaserJet 4000, lpt1 printer, which works fine in suse. Searching and posting on the Vbox forums turned up that lpt1 is not supported in the current vbox and that I need to set up a virtual network, set up the printer as a network printer and set it up as an lpd/lpr printer in Vbox WinXP. Have tried many different ways to do this without success, I think the problem is I do not know how to set up a network printer in Linux.
The virtual network is vboxnet0, which does show up in ifconfig, along with my eth0 net, and I can ping the windows guest, gateway and the host from either side host:suse/guest:winXP) respectively. Have tried numerous ways of setting up printer in YaST which works in suse but still does not work from WinXP guest. Have read the suse manual and several sources and searched forums with no results.Finally I am thinking I just don't know how to set up a network printer in linux. Using cups, kde, suse 11.2, don't know what else to tell. Samba is installed, although I am not using it to the best of my knowledge.

I've been trying to understand how Linux creates the network/interfaces on a machine (been reading the Linux admin guide), but as I'm pretty new to this subject, I've got lost in the forest.
To provide with my goal:
1.) Learn about network setups on Linux
2.) Be able to maintain my own (virtual) network
3.) Configure my (virtual) network

I have a server that is on both a standard network and a virtual network, as follows: server1 attached to standard network server1 acting as Dom0 with two linux DomU guests (under Xen) I only have one network card. How do I configure server1 to have a different hostname on the standard network than on the virtual network? Here are the relevant network configuration files for server1:
/etc/sysconfig/network-scripts/ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=none
NETMASK=255.255.255.0
IPADDR=192.168.122.9

I have a Slicehost VPS and I'm trying to set up PPTPD on it. I only have one IP address (the public IP of the box). All the PPTPD howto's I've seen rely on assigning remote clients IPs from the local subnet (e.g. the PPTD server's local IP is 192.168.0.20, and remote IPs are taken from a pool of 192.168.0.30-40).
However I don't think I can do that as I only have the one IP address on Slicehost's network - that public IP (and all other IPs in the segment are public). So what I really want to do is to be able to create a private LAN segment or virtual network adapter and have VPN clients assigned addresses in that segment, then routed out onto the Internet effectively using the PPTPD box as a router. I am using Ubuntu Hardy (LTS).

I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.

I have OpenSuse 11.2 installed and I'm currently testing out Magento Commerce which is working as expected. In order to create fake customers the application requires a unique e-mail address for each customer. I currently use postfix and have all the e-mails being sent to my providers domain which i only have 2 email user accounts. How do i set up virtual e-mail addresses like joeblog@fakedomain.com and maryblog@fakedomain.com such that when the Magento Application sends emails to these addresses I would like to access the corresponding mail boxes on the same host. (i.e. the machine i run Magento on)

I only have one IP adress to access the server. But the server will host 3 web sites and I want them to be hosted in a vm. So, I want to setup 3 virtual machines to do it and use apache reverse proxy and vhosts to redirect the domain requested to the right vm. Now. I understand the concept, but I am not an expert to set that up....
I have an openSUSE 11.3 server. So, I have to set a virtual machine server, is that right? I have been told that I cannot do it with VMware server in oS 11.3. Can I use virtualbox for this? I only have to install virtual box? Is there a special version to install? Once the virtual machine server is install, is it trivial to create 3 vm? So, I want to know wich are the steps I have to take to set that up.
