/etc/network/interfaces resets after booting debian

[Chris]

Not sure why this is happening but for some reason /etc/network/interfaces resets back to some kind of default after booting from ALT-F to Debian. If I make changes to interfaces file and save and reboot just debian from within the debian environment it seems to be fine and keeps the changes. if I make changes from and reboot the box which boots to alt-f (then I manually boot debian) the changes I made to interfaces file are lost. If I boot to alt-f and edit the interfaces file and save it then boot debian the changes are lost again. So Im not sure why or what is causing this but it kinda seems as though it has something to do with switching between alt-f and debain. the below code sample is what interfaces gets replaced with after a reboot.

auto lo
  iface lo inet loopback

auto eth0
iface eth0 inet static
  address 192.168.1.223
  netmask 255.255.255.0
  broadcast 192.168.1.255
  mtu 1500
  gateway 192.168.1.1

has anyone else seen this?

Sorry forgot to mention this is happening on my dns323 with alt-f rc3 flashed. ;)

/etc/network/interfaces is created by the Debian script /usr/sbin/debian everytime it is invoked:

        if grep -q '^iface eth0 inet static' /etc/network/interfaces; then

                cp /etc/network/interfaces $debdir/etc/network/

        else

                cat<<-EOF > $debdir/etc/network/interfaces

                        auto lo

                        iface lo inet loopback

                        auto eth0

                        iface eth0 inet dhcp

                EOF

        fi

        cp /etc/hostname /etc/resolv.conf /etc/hosts $debdir/etc/

Thanks. I think I know what to do with that info. :)

OK. So I was mistaken. I thought I knew what to do with that information but I guess I was wrong! :( Luck me I made a backup of that script before I went crazy on it. So what is the best way to not have it overwrite the interfaces file at excute debian?

Thanks,

Chris

Come to find oit it just took a while the first boot. Thought I hosed my debain/alt-f firmware for a min there. What I did was simply remove the mentioned lines from the debain script and it working just fine. Thanks.
