Post subject:  ifupdown (Debian Sarge) woes
I'm trying to set ifupdown to use a static ip. Its not working.

relevant information:

uname -routput:
Code:
2.4.29-linode39-1um


etc/network/interfaces:
Code:
# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.

# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback

# The following is automatically put in there, but incorrect
# eth0 uses dhcp
auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
    address 66.160.141.163
    network 66.160.141.0
    netmask 255.255.255.0
    broadcast 66.140.141.255
    gateway 66.140.141.1
#auto eth0:1
#iface eth0:1 inet static
#       address 66.160.141.167
#       netmask 255.255.255.0


ifup -a -v output
Code:
ifup: interface lo already configured

run-parts --verbose /etc/network/if-pre-up.d

 route add default gw 66.140.141.1  eth0

route -n after ifup:
Code:

66.160.141.0    0.0.0.0         255.255.255.0   U     0      0        0 eth0


Is it just me, or is ifupdown bugged?

Thanks in advance for any help.

You've got a typo.

Code:
iface eth0 inet static
    address 66.160.141.163
    network 66.160.141.0
    netmask 255.255.255.0
    broadcast 66.140.141.255
    gateway 66.140.141.1

Look at address/network -- they reference 66.160, but broadcast/gateway references 66.140.

You need to make them all match.
