Issue/Introduction

When trying to copy keys over to a host using "ssh-copy-id", the error below appears:

[gpadmin@mdw greenplum-db]$ ssh-copy-id sdw16n 
/usr/bin/ssh-copy-id: ERROR: failed to open ID file '/home/gpadmin/.ssh/iddummy': No such file or directory 
(to install the contents of '/home/gpadmin/.ssh/iddummy.pub' anyway, look at the -f option)

Environment

Product Version: 6.19

Resolution

This occurs because gpssh-exkeys creates a blank "iddummy.pub" file in .ssh directory, and ssh-copy-id uses this file when trying to copy keys over.

Either deleting the "iddummy.pub" file or explicitly passing the identity file (ie. "-i id_rsa.pub") should resolve the error.
