I am new at PBSPro. To installed PBS Pro I followed the instructions at https://github.com/PBSPro/pbspro/blob/release_19_1_branch/INSTALL
All went well except the last step which is to run a PBS Pro command:
$ qstat -B
The error message says:
qstat: cannot connect to server eric9020-optiplex (errno=111)
How can i fix this issue?
