OpenSUSE Network :: Routing From Host To Vmware - Server - Guests
Oct 30, 2010
I just installed (n this 11.2 system) vmware server (v 2.02), to have access to a few small systems. One of them is a 11.1 guest which I just upgraded to 11.3, successfully (almost).
I have a problem, though: from the host I can not ping/ssh the guest.
Guest to host works fine (including names).
Code:
The firewall is down on both sides. I don't see anything with iptraf in the guest. The IP addres of the guest is correct, unless I'm too tired to see.
Why?

My special networking configuration.
The case: I'm running two dedicated Linux servers (openSUSE). Both servers are connected through public IP addresses to the internet. Each server hosts a VMware with another Linux inside.
SRV1 and SRV2 are the entry points for OpenVPN from external clients. SRV1 and SRV2 are although connected through an OpenVPN connection for save data sharing.
My problems:
SRV3 can't connect to SRV2 and SRV4.
SRV4 can't connect to SRV1 and SRV3.
External OpenVPN clients connected to SRV1 can't reach SRV2 and SRV4.
External OpenVPN clients connected to SRV2 can't reach SRV1 and SRV3.
Here are my configurations:

I have been using VMware Player for some time to host Fedora VMware images on Windows XP. I have been using Fedora 11 and 12 (both 32 and 64 bit) and recently started to use Fedora 13.
I use as a base the images provided by thoughtpolice. http://www.thoughtpolice.co.uk/
I usually install VMware tools and also keep the images updated (yum update) which sometimes changes the kernel.
I have recently had problems with the snapshots not having a network when I restore them. So far I don't have the problem with Fedora 11 and do have it with Fedora 12 (but used not to). I do have it with Fedora 13.
In each case the problem goes away when I uninstall the VMware tools and comes back when I install them again.
One of the symptoms is that SElinux complains about not being able to do something with /var/run/vmware-active-nics.
It looks to me that something is incorrect in the actions being taken when the snapshot is being restored. It does not happen every time and sometimes the network restores itself.
The network can be restored by rebooting the image.

I just had one hell of an experience trying to get openSUSE 11.2 to run on VMware server 2.0 on a Windows XP host. I am posting some instructions on how I finally got things working.
1) Download the openSuse iso image (and add-on CD if needed)
2) Download and install the VMWare server
3) Before you try to start the server console, you will need to configure the web access to allow you to log on. go to press Start->Programs->VMware->VMWare web access->Configure Tomcat
4) on the logon tab check logon as: option
5) add your account there and set the password
6) Now in your web browser (I use firefox) access the console via: [url] [url]
7) Before you start to create a virtual machine, you will want to set up the server to have access to your iso's. The server will only allow VM's access to specific directories through "datastores". You can either move the iso images to what has been specified as the default datastore... or create another datastore that points to the where you have the iso's.
8) Now we can create our virtual machine. This is simple, just press the button and follow the prompts.
a) at some point it will ask about an CD-Rom, you will want to use your suse DVD iso image. Select the option and then navigate the datastore that contains the image. Once found click and continue.
b) Network interface has 3 choices:
Bridged - the virtual machine will appear on the network as any other computer. Allows the VM to host server applications. User needs to have control over the network to ensure DHCP requests are handled (or static IP is assigned).
NAT - VMWare server will manage a virtual router, the VM is then connected to this router. On this router, the hosts internet is used as the WAN. Users do not have to have control of the network, but will have to setup port forwarding in VMWare to host server applications
Host Only - This means that the virtual machine can only talk to the host. The only way to get networking is to have a proxy through the host machine. This is setup on the host independent of VMWare. Users do not need control of the network, but control over the host. I doubt you could host server applications though.
9) With the VM created we can start it up. We can open a window to it through the console tab of the VMWare server console. When I first started it, it was stuck looking for an OS once the console finally rendered the graphics. A reset, an F2 at the post and selecting the appropriate boot media for boot got the installation started.
10) Install Suse as you would any other suse installation. I added a separate partition for swap, but kept the rest on one big one. Others may still want to maintain the separation of home and root
11) ---- Important Error/Solution ----
Once the installation has completed many will notice that the mouse or keyboard does not work! This was the source of my biggest head-ache. Some may think it was a problem with VMWare tools... I tried that to fix that and found the tools were working properly.

I'm trying configure my server for routing between vlans, but I'm having troubles with my server after that vlans are set. I can create vlans and routing is OK, but when I trying remove a vlan, restart the network script or restart the server, the CLI freeze and then I can't do anything. Even Ctrl+C or Ctrl+Z isn't work. I can use other terminal or do other SSH connection (if the network interface used by ssh isn't crashed), but if I try use a ifconfig per example, crash again. The unique solution is restart the server. Nothing about this is found in the log.
Opensuse 11.4
Kernel: 2.6.37.6-0.5-desktop

host hibernates while virtual machines are running on it.
In my case, my Ubuntu 10.04 host hibernates nicely, but when it resumes, virtual machines are reset and their state is lost.

We got a new server with 2 network interface cards with 4 MAC addresses in total. We would like to run two virtual machines (vserver1 and vserver2); one should connect via eth1, the other via eth2, and the host (mainserver) via eth0. The content of /etc/network/interfaces is as follows:
[Code]....
A connection from mainserver to vserver1 or vserver2 is not possible; a ssh connection from mainserver to vserverx ends with a login to mainserver.

Just something that struck me while working on our virtual servers today.
I have bonded 3 NICs at the host in Ubuntu Server 8.04 LTS. They are using mode 0 for Round-robin. Point is to increase the speed/performance of all the servers, but mainly the fileserver. The fileserver is a virtual server running Ubuntu Server 8.04 LTS on VMware Server 2.0.
1) I noticed the NIC in the slave OS reported link speed as 1000 and Im unable to change it as the NIC (virtual one) doesnt support it. Does this not really matter, as the NIC doesnt exist, and it will run at higher speeds anyway? Or do I have to remove the bond on the host, bridge all 3 interfaces from the host to the slave OS, and then make a bond in the slave OS?
2) While at it, does mode 0 only increase performance on data being sent from the host or does it also increase the available incoming bandwidth?

Not sure if this post belongs here, but here it is.
Host: Win server 2003
Guest: Ubuntu server
Host: IS able to ping guest. Firewall is OFF. NOT able to access guest (which is a web-server) at browser.
Guest: NOT able to ping host. Running a web server, you can check the website: (pegajosa.com) is running under that virtual Linux server.
Problem: guest needs to access host's sql database and/or any resources.
Network: is bridged.

We have a 10.0.0.x network with a working DNS Server (BIND) setup. Recently we purchased Watchguard firewall and configured three networks, so that our internal network can be divided into three networks and talk to each other through firewall routing. So I configured three ips 192.168.0.1,172.16.0.1 and 10.0.0.1 for local network card in the firewall router. I separated three networks and individually configured machines with static ip and given gateway as the above ips. Now, I need to configure DNS server for each zone in the same server which is in the network 10.0.0.x, is this possible?. If yes do I need to setup ip aliases for eth0 in the DNS server with different ips from each network?

I created a VMware Workstation VM with OpenSUSE 11.2. When I copy the VM to a new location the network configuration disappears. If I go into the networking control panel and save, the interface names are changed. Originally had 2 nics as "eth0" and "eth1", copy the vm, configure network and the interfaces are now "eth2" and "eth3". How do I get back to my original configuration?

I have a mac and an openSUSE box connected wirelessly to a router. From my mac, if I ping the Linux machine by both ip address and hostname "elmo.local", I get a response. If I ping my mac from the Linux machine using its ip address, I get a response. However, if I ping the mac from the Linux box using its name "kermit.local" - nothing!
This means in order to share files between them via the network, I have to use the ip address rather than name, but I'd rather not. When I had Ubuntu installed instead of openSUSE this all worked fine out of the box, so I'm assuming it's a problem with the setup of openSUSE rather than the router or the mac.

I have installed fc12 on my core2due machine, and I have installed the vmware server on it, its rpm is installed successfully with out any error, after that a message is displayed
The installation of VMware Server 2.0.2 for Linux completed successfully. You can decide to remove this software from your system at any time by invoking the following command: "rpm -e VMware-server".
Before running VMware Server for the first time, you need to configure it for your running kernel by invoking the following command: "/usr/bin/vmware-config.pl".
I tried this command and find the this message
[Akram@localhost Downloads]$ su -c "/usr/bin/vmware-config.pl" Password: Making sure services for VMware Server are stopped.
None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? [yes] yes
Using compiler "/usr/bin/gcc". Use environment variable CC to override.
Your kernel was built with "gcc" version "4.4.2", while you are trying to use "/usr/bin/gcc" version "4.4.3". This configuration is not recommended and VMware Server may crash if you'll continue. Please try to use exactly same compiler as one used for building your kernel. Do you want to go with compiler
"/usr/bin/gcc" version "4.4.3" anyway? [no] yes
What is the location of the directory of C header files that match your running kernel?[/usr/src/linux/include]
Now it asks me in last lines that "What is the location of Directory of C header files that match your running kernal?"

I have just loaded Suse 11.4 and have had (2) problems, 1st: When I installed some additional programs, such as, Scribus, the system showed them as installed but they did not show up in the "applications" menu any where. I finally tracked them down and edited them in and they work fine - Why aren't they being automatically placed into the menu system? 2nd: I have a home network setup and all systems can see and work with each other, however, the host system is not shown as if it did not exist at all. for example; if I go to "network services" and select "Samba Shares" if other computers are connected it will show them but not the host - if no other computers are connected it shows nothing. On my 11.3 system it shows the host eg; "Linux-12fx blah blah" this is of course my host machine. I have replicated all of my settings on the 11.3 settings on my 11.4 system - no luck!

I just installed SUSE in a VMware to test it out. A problem i've had with VMware before was getting the wireless to work. I was wondering if anyone knows a way to get the wireless to work over the VMware and in SUSE. I know this may not particularly be a SUSE question but all I saw in the VMware forums was one response that said it was not possible.

I've been reading for a while about samba but I haven't found a solution to my problem yet.I'd like to know if, the configuration I have in mind, is possible at all ("security = user" is what I'm using now).I want a directory to be:
1) read only for guests and some UNIX users;
2) write for some other UNIX users.
The advantage of this configuration would be that every single user in my LAN (with or without a UNIX account) would be able to read the content of the shared directory Music and I (UNIX user andrea) could manage the folder directly trough samba preserving the correct owner/group and permissions on the new files/folder created.
Notes about my configuration above:
1) as it is now every user gets authenticated by samba as nobody so even I (andrea) cannot write in it;
2) commenting out the line "guest ok = yes" I can authenticate as "andrea" and write in it but guest access is not possible any longer.

EDIT: Thread name should be "No network on XEN guest ofcourse". I am trying to run OpenSUSE 11.3 as guest in OpenSUSE 11.2 as host. First problem I came across was libvirtd service wasnt started and after that I was able to install guest OS. Now there is a problem as guest doesnt have connection with internet.
Here is the script for the guest
name="opensuse113"
uuid="2f1f1d63-c416-a9c4-3bc1-4e92e248c5cc"
memory=512
maxmem=512
[code]....
Here are the images that show how it is all configured taken from Virutal Manager.
network1 png
tmpbridge png
host config png
The last image is from the guest config I just named it badly. Observe that xen is up and runing and there are no others issue this far.

OpenSUSE version: 11.2 *and* 10.0 I am unable to send email. It appears I am being blocked by my ISP [URL]... A Wireshark trace shows ICMP type 3 Code 13 - "Administratively filtered". It's important to note that I don't know exactly when the problem started, because I seldom use my ISP email account, I use Yahoo web mail due to the "throwaway" nature if I get hit with spam. I only discovered the problem when testing the functionality of 11.2. I suspect the problem started several months ago: I restored openSUSE 10.0 and the problem exists there too. I wish I'd sent that last email via 10.0 before the upgrade.
The weird thing is that using Windows 2000 box I can get a successful connection using telnet (Telnet also fails on the openSUSE box.) It appears to me there is something in the Linux TCP stack that Teksavvy doesn't like. I am on dial up and I pointed this out to Teksavvy tech support, as I am probably the only person left on dialup and the reason no one else has reported the problem

I am running
Code:
On my laptop (HPDV7), using DHCP for network access, KDE4.
I use Network Manager to manage wired and wireless connectivity.
I also have Samba server running for connectivity to Windows machines.
My router runs DD-WRT.
How do I tell this HPDV7 system to propagate a Host Name up to the router?
In the DD-WRT status screen, I see Host Name as "*" associated with the assigned IP address.
I cannot, for example, ping my HPDV7 machine from my windows machine, I assume because the router (also providing DNS for my network) does not provide the name to address translation.
I CAN ping the IP address directly, and Samba connectivity from the Windows machine to HPDV7 works.
