RE: Stuck on bad change to etc/network/interfaces

["Harry Cochran" <h.cochran@comcast.net>]

Thanks,

	I have attached the last lines from the boot crash with Kernel Panic for
your information. As to why something as simple as this interfaces file:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian
installation
# (network, broadcast and gateway are optional)
auto eth0
iface eth0 inet static
       address 192.168.0.2
       netmask 255.255.255.0
       network 192.168.0.0
       broadcast 192.168.0.255
       gateway 192.168.0.1
#
auto eth1
iface eth1 inet static
        address 192.168.1.1
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
#        gateway 192.168.1.1

should cause a kernel panic is beyond me. Obviously, I'm trying to set the
A180 up as a proxy server. The router is 192.168.0.1 and the primary switch
for the LAN is 192.168.1.5. Any ideas would be appreciated.

Thanks again,

Harry

If you append 'init=/bin/sh' to your PALO command line, you will get
dropped at a command prompt just after the root file system is mounted.

Run mount -o remount,rw / to get a read-write '/', and then
you can edit /etc/network/interfaces to fix your bug.

I'd be interested in seeing the kernel panic you're getting though,
I can't conceive of how something in there could be causing a panic.

Thanks,
	Kyle
