Ok .. there i found the problem and a solution.
The pbs_srver and pbs_sched use different netword adapters.

Now i have another problem ...  i see it but don't really know how to solve 
it.

pbs_mom;Svr;pbs_mom;im_request, bad connect from 192.168.1.2:1022 - 
unauthorized (okclients: 192.168.0.1, ...

The problem is, that the nodes have 2 network adapters, one for 
calculating-communication  and one for files-transmission to the frontend.

The frontend knows the nodes with the name node and the ip 192.168.0.*
On the nodes this network is called slow. That means: node02 connect to node01 
over this network, than he has to connect to slow01 (192.168.0.1).   
But if the node02 connects to node01 via the address node01, than it use the 
ip 192.168.1.1.

Is there a solution to fix it ?

With best regards
