Hi Kathy/Atul, I am configuring 10g RAC on vmware (RHEL AS4 & 2 nodes).When I am configuring ssh without password I am unable to do so. Please see the steps I followed rac1 cd /home/oracle/ mkdir .ssh chmod 700 .ssh cd .ssh ssh-keygen rsa ssh-keygen dsa Performed same steps on rac2 then at rac1 touch authorized_keys ssh rac1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys --followed steps ssh rac1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys --followed steps ssh rac2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys --followed steps ssh rac2 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys chmod 644 ~/.ssh/authorized_keys performed the same steps at rac2 --establish user equivalency as oracle user exec /usr/bin/ssh-agent $SHELL /usr/bin/ssh-add then i typed at rac1 ssh rac1 date --asking me the password (without password if i enter it is asking me password ssh rac2 date --- same above at rac2 ssh rac1 date --same above ssh rac2 date --same above Any good suggestion (I can use rsh/rcp) to resolve ssh without password.
