Greetings, Does anyone use LTSP virtualized with 2 NICS? I'm using KVM/libvirt and Ubuntu 10.04. How do I configure this? It seems that I can't select a real physical NIC. I was thinking that my virtual LTSP could have the first NIC bridged to the hosts br0 and the second NIC be linked to the hosts eth1.. but this doesn't appear to be the case. Maybe bridge them both? Make br0 for eth0 and br1 for eth1? Any ideas? Thanks, -Andy |

Here's abeehc's /etc/network/interfaces file as an example: # This file describes the network interfaces available on your system # and how to activate them.

Mine is more simple for testing purpose at home. asmok@ubuntu:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet manual auto br0 iface br0 inet static address 10.0.2.10 network 10.0.2.0 netmask 255.255.254.0 broadcast 10.0.2.255 gateway 10.0.2.1 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 I do run four distros, not in same time because of same fixed ip for LTSP server and lack of memory, in KVM: Debian 6.0, DebianEdu 6.0, openSUSE 11.4 and Edubuntu 11.04. Because of DebianEdu I do use same network/router for all four LTSP test servers. "The default installation does a lot of preset choices for the network. So you have to make changes in quite a few files to get the installation to work as you would like, and at the same time get the machines to behave as wanted." "The simplest solution is often to set up a router/firewall in front of the Skolelinux network. Set the firewall to NAT to the IP on the outside and let your fine Skolelinux network be left peacefully behind the firewall." http://wiki.debian.org/DebianEdu/HowTo/ChangeIpSubnet Here is DebianEdu. root@tjener:~# cat /etc/network/interfaces # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) # This file was created by debian-edu-profile during the Debian installation # The loopback interface auto lo iface lo inet loopback dns-search intern auto eth0 iface eth0 inet static address 10.0.2.2 netmask 255.255.254.0 broadcast 10.0.2.255 gateway 10.0.2.1 # The commented lines below is to be used if a DHCP server is in use #iface eth0 inet dhcp auto eth1 iface eth1 inet static address 192.168.0.254 netmask 255.255.255.0 broadcast 192.168.0.255 # The commented lines below is to be used if a DHCP server is in use #iface eth1 inet dhcp Here is Edubuntu, ltsp@edubuntu:~$ cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.0.2.2 netmask 255.255.254.0 network 10.0.2.0 broadcast 10.0.2.255 gateway 10.0.2.1 dns-nameservers 10.0.2.1 auto eth1 iface eth1 inet static address 192.168.0.254 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 Best Regards Asmo Koskinen. |
