Moin Dennis,

you don't need 138+ ini files. 2 Are enough. You need one "master"
dnetc which feeds all the others.
id=plasmahh at gmx.net

Fire the master up with `~/bin/dnetc -ini ~/dnetc/master.ini`.

All the "client" dnetcs have the following:
id=plasmahh at gmx.net


Every client goes with the following command line (make it a shell
`test -e ~/dnetc/$HOSTNAME || mkdir -p ~/dnetc/$HOSTNAME; ~/bin/dnetc\
-ini ~/dnetc/client.ini -inbase ~/dnetc/$HOSTNAME/buff-in -outbase\
~/dnetc/$HOSTNAME/buff-out -ckpoint ~/dnetc/$HOSTNAME/buff.cp`
That way you've got your own buffers + checkpoints for every client.

Hope this works as I thought it does. Have to leave to work now...
Baahh! It's f***ing late again...
