ifup eth1 gives error but successfully ups and works why?

Hello,
Why it happens that whenever i try to up interface which is
previously down by me gives error. what should be wrong in my
configuration which is static IPs to eth0 and eth1

[root@localhost root]#ifup eth1
ipcalc: bad ip address: 10.0.0.
Error: an inet prefix is expected rather than "10.0.0./".

my configuration is
eth0 Link encap:Ethernet HWaddr 00:08:A1:43:61:F5

Maybe you should let us see what is in the config file for eth1 (eg
/etc/sysconfig/networ-scripts/ifcfg-eth1 on Redhat/Mandrake) so we could
see what you have in there.
Ie, how can we know what is wrong with your configuration if you do not
show the configuration file to us?

Which distribution (Debian) ?

What is in the eth1 configuration specification file?

The error message says that there is a bad IP address specification
associated with eth1 ('10.0.0.' or '10.0.0./'), maybe a route or
gateway.

(In Debian, the file is /etc/network/interfaces).

Both interfaces are on the same network (same local route), so only one of
those interfaces (1st matching in routing table) would actually be used
(unless more specific -host or -net routing was added, or advance routing
per Adv-Routing HOWTO).

This seems to be OK. It seems that your script
is broken. The error message is clear.
