Hi, I have a very strange hostname/IP resolve problem :
>From qmaster, if I qping a compute node : qping compute-0-4 537 execd 1 Answer of compute-0-4 : endpoint compute-0-4.local/execd/1 at port 537: can't find connection access denied: client IP resolved to host name "". This is not identical to clients host name "" endpoint compute-0-4.local/execd/1 at port 537: can't find connection I have the same problem for all my nodes but this problem does not occur with qsub or qstat... ! So SGE is working fine (except that little error). I know that I have changed some informations in my /var/named/... files and in my /etc/hosts , but I can not find my error. The qping in the other direction, execd to qmaster, is working fine. The result of hostname -s on qmaster give the content of $SGE_ROOT/$SGE_CELL/common/act_qmaster on all nodes and on qmaster. If I try to ping qmaster from my nodes, IP address resolution is ok (I tried also with nslookup). My version of SGE is old : GE 6.2u2_1 How it should be configured on qmaster (named and host file ?) ? Thanks -Regards, Remy
