PBS install issue no route between server and client

Qstat: cannot connect to server amaster (errno=113)

Please check your DNS and /etc/hosts for the name resolution of “amaster” firewall settings ( 15001 to 15009 and 17001 should be open between server/computenodes) SELinux disabled and system rebooted check and share this command output pbs_hostn -v amaster /etc/hosts should be the same both on the server and compute nodes

Also check your netmask to ensure traffic can pass between subnets. Sounds like an underlying network issue.
