(sorry if this is a dupe)

 I have mpich-1.2.1, with linux-2.4.x/2.2.x mix
 
 The disk on my master node crashed. Following a restore,
 I find that I'm asked for passwds for the slave machines
 on running mpirun commands like
 
 mpirun -np 4 foo
 
 other info
 
 1. The multiple copies of foo execute properly
 
 2. I can ssh to all machines without a passwd
 
 3. I can run commands like
 #ssh -n slave_node date
 
 and get the date without a passwd
 
 4. The environmental variables MPI_P4SSPORT and MPI_USEP4SSPORT are set
 correctly on all machines.
 
 5 when I run
 
 chkserv
 
 for each machine I get
 
 Bad message from machine_name: :Password
 :
 
 6. serv_p4 -o -p 1234
 
 is running on all machines (according to ps)
 
 Does anyone know what I've missed?
 
 Thanks Joe
