[Antonio J. Peña]

Hi Sufeng,

Can you ping/ssh exactly this name "iocfccd1.aps.anl.gov" from iocfccd3?

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[2]] HYDU_sock_connect 
(./utils/sock/sock.c:174): unable to connect from "iocfccd3.aps.anl.gov[3]" 
to "iocfccd1.aps.anl.gov[1]" (No route to host)
[proxy:0:1 at iocfccd3.aps.anl.gov[2]] main (./pm/pmiserv/pmip.c:189): 
unable to connect to server iocfccd1.aps.anl.gov[1] 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
