Re: installation issues LMCE 12.04 (network installation)

Just rebuilt my server after another crash, has been a while, using 12.04 dvd build on 06 Nov, also did an update.

When I try to configure a static network configuration and setup DNS to a separate IP, via the web admin, it breaks the network configuration on a restart, both eth0 and eth1.

Seem to sort out the network issue, by going in the Orbiter and configuring the network settings there, which brings back up the interfaces.

An issue remains, I am not getting the DNS i want set to work to resolve. Checked under the device core "IPv4 Network Interfaces" and all seems correct.

Any thoughts.

hcaine How many interfaces dor you have on the core including wireless interfaces?
there is a third network interface unconfigured on the db this one "|,, |" and this card is unconfigured set on /etc/network/interfaces
this one:

# ---   ---
iface  inet static
  address
        netmask
  pre-up sysctl -q -e -w  net.ipv6.conf..disable_ipv6=0
        # DNS Settings for Internal Net
        dns-nameservers
        dns-search LinuxMCE

I'm working on multiple network interfaces configuration with wireless cards as well,
i'm going to search where the third card what is unconfigured comes from.

CentralMedia: I've no clue myself, hopefully someone with more knowledge in that area can help.

hcaine: I have tried and tried and I've been unable to recreate the issue you are having with the 3rd blank nic adaptor.  ",, |" in the device data it's these characters that are defining this 3rd blank nic.  Removing those should inhibit the unwanted behaviour.

I have exactly the same issue with no third network adaptor.

Fresh installs are not exhibiting this behaviour so there must be something you guys are doing, perhaps in webadmin, to configure your networking.  If we can narrow down what/where then we can fix it.

Or maybe one of your PCI devices is identifying itself strangely. So if you didn't do anything manual, please pastebin the output of lspci

So, idiot that I am...  I tried the instructions in the first post and I can recreate this.  Not sure why it's happening but hopefully it will put me closer to a solution.  Thanks for testing and reporting everyone!

Initial issue is solved, should be no more extra 'blank' network interfaces.  http://svn.linuxmce.org/trac/ticket/2536#ticket

Let's open up new threads for any other issues.  Thanks again guys!
