[Difx-users] DiFX mpirun problem

[Stuart Weston]

Do IP addresses get added in when the code is compiled ?

The correct IP address should be 163.7.128.11 and not 156.62.231.167.

I have checked "/etc/hosts" on both servers. Also stop/start "rpcbind" just
in case. I have tried putting the IP addresses in the machines file and not
the host name. Still get the error ?

Tried with a very simple mpirun and thats good, ie:

oper at ww-flexbuf-01 DiFX-2.4.3 v534a> cat hosts
163.7.128.194
163.7.128.11

oper at ww-flexbuf-01 DiFX-2.4.3 v534a> mpirun -np 2 -hostfile hosts hostname
ww-flexbuf-01
wark167

Any ideas as to why it insists on picking up the wrong IP address ?
