Yes, that's what's supposed to be there. The destination is the network
that the interface is connected to, or can 'see'. eth0 sees all the
machines on 192.168.1.*, so if the Debian box is on 192.168.0.* it won't
be seen. If you change the netmask to 255.255.0.0 it will see 192.168.*.*,
which includes 192.168.0.* and 192.168.1.*, so all machines will be
visible. However, that's not going to solve your problem, because both
machines have to be able to see each other - having the SuSE box being
able to see the Debian box is of no use if the Debian box can't see the
SuSE box. 

The two machines *have* to be on the same subnet. If the Debian box is on
192.168.0.1, and you don't want to change the config on the Debian box,
then the SuSE box *has* to be on 192.168.0.* somewhere - like 192.168.0.5. 

All linux boxes use the same basic tools - ifconfig, etc., you should find
it equally easy to change either box.

Cheers,

Alex.
