Hi,

I just got tkined installed on a linux system and I am very impressed what
it does for me.

The only problem I had so far, was that when I tried to discover our campus
network, some hosts returned a netmask of 0.0.0.0 (eg kepler.dmu.ac.uk)
These are PCs with trumpet winsock. They have their netmask configured
correctly. But for some reason, they don't tell.

Anyway, this prevented IP discover from producing a sencible map.

My solution to the problem was, that I canged the discover module to assume
a netmap of 255.255.255.0 when ever it finds a node returning 0.0.0.0

It works for me. But I am not quite sure whether this is a sencible thing to
do.

Did anybody else encouter this problem?
