Hi All I know Networking seems to be the biggest problem discussed on the list, but I'm have seriously difficulties. I've a 2.6.23.14 kernel on the host and also a 2.6.23.14 UML kernel. UML boots correctly, although I don't have the SKAS3 patch. When I try and setup networking on host I get the following error; host:/home/brendan/linux-2.6.23.14-uml # tunctl -u root -t host-uml Set 'host-uml' persistent and owned by uid 0 host:/home/brendan/linux-2.6.23.14-uml # brctl addbr uml-bridge host:/home/brendan/linux-2.6.23.14-uml # ifconfig host-uml 0.0.0.0 up host:/home/brendan/linux-2.6.23.14-uml # ifconfig eth1 0.0.0.0 host:/home/brendan/linux-2.6.23.14-uml # brctl addif uml-bridge host-uml host:/home/brendan/linux-2.6.23.14-uml # brctl addif uml-bridge eth1 host:/home/brendan/linux-2.6.23.14-uml # brctl show bridge name bridge id STP enabled interfaces uml-bridge 8000.000ae4ac1957 no host-uml eth1 solaris:/home/brendan/linux-2.6.23.14-uml # dhclient uml-bridge Internet Systems Consortium DHCP Client V3.0.5 Copyright 2004-2006 Internet Systems Consortium.

I also own the Jeff Dike book (which is where I got the above from) so any references to that are OK also. Thanks in advance Brendan McNally Ireland |

Hi All I've resolved the problem below, and I now have a correct bridge (I think). When I boot the UML session though and try UML# ifconfig eth0 192.168.0.153 up I get SIOCSIFADDR: No such device eth0: Unknown interface: No such device eth0: Unknown interface: No such device ifconfig -a brings back just lo interface. I'm using the FedoraCore5-x86-root_fs filesytem Brendan On Feb 11, 2008 10:27 PM, Brendan McNally <bre...@gm...> wrote: > Thanks Jeff, > > I'll look at fixing this problem.
