[Wien] dstart_mpi error

[karima Physique]

Dear wien2k users:

Using the folowing machines files :
lapw0:master:12
dstart:master:12
1:master:12
1:node1:12
1:node2:12
......
the calculation works very well, but using the following machines file:
lapw0:master:12  node1:12  node2:12
dstart:master:12  node1:12  node2:12
1:master:12
1:node1:12
1:node2:12
.......
I got the following error:

unable to get host adress calcul.local for (1)
unable to  connect to server  calcul.local at port 44295 (chek for
firewalls!)
we note that  calcul.local is the host to connect to w2web.
I ask you any suggestions to solve this problem
