Hello Team,

we are pulling files from the SunOS server to the Linux server. RSYNC will run from the Linux server to pull files from the SunOS server.
Below command is working fine. We would like to use passwordless SSH.

rsync -zarvh inovteam@<SunOS server IP>:/data/CDR/ocscdr/voice/backup_ocs_voice/ /data/CDR

Could you please advise how to modify above rsync command to pull data without specifying password?
