[root at frontend root]# cd /opt/gridengine/utilbin/lx24-amd64/
[root at frontend lx24-amd64]# ./gethostbyname network-0-0.local
h_errno = HOST_NOT_FOUND
gethostbyname() failed: Success

[root at compute-0-7 root]# cd /opt/gridengine/utilbin/lx24-amd64/
[root at compute-0-7 lx24-amd64]# ./gethostbyname network-0-0.local

[root at frontend root]# qconf -sel
frontend.local
compute-0-0.local
compute-0-1.local
compute-0-2.local
compute-0-3.local
compute-0-4.local
compute-0-5.local
compute-0-6.local

[root at compute-0-7 root]# qconf -sel
denied: host "network-0-0.local" is neither submit nor admin host
