[mpich-discuss] run hello world on multiple server

[Sufeng Niu]

Hi,

Sorry to bother you guys on this stupid question. last time I re-install OS
for all blades to keep them the same version. after I mount, set keyless
ssh, the terimnal gives the error below:

[proxy:0:1 at iocfccd3.aps.anl.gov] HYDU_sock_connect
(./utils/sock/sock.c:174): unable to connect from "iocfccd3.aps.anl.gov" to
"iocfccd1.aps.anl.gov" (No route to host)
[proxy:0:1 at iocfccd3.aps.anl.gov] main (./pm/pmiserv/pmip.c:189): unable to
connect to server iocfccd1.aps.anl.gov at port 38242 (check for firewalls!)

I can ssh from iocfccd1 to iocfccd3 without password. Should I shut down
all firewalls on each server? I cannot find out where is the problem. Thank
you
