Hi:
I'm having trouble configuring ssh on a two-node 10G RAC cluster.

After the configuration, when I did a ssh to the other node , I got the warning message- "
Warning: No xauth data; using fake authentication data for X11 forwarding".

I followed the steps in the installation guide.

As oracle,

1) mkdir ~/.ssh
2) chmod 755 ~/.ssh
3) /usr/bin/ssh-keygen -t rsa

this creates two files in .ssh - id_rsa and id_rsa.pub 4) /usr/bin/ssh-keygen -t dsa
this creates two files in .ssh - id_dsa and id_dsa.pub
5) cd .ssh; cat  id_rsa.pub id_dsa.pub > authorized_keys
6) ftp authorized_keys to the other node
7) chmod 644 authorized_keys on both nodes
8) exec /usr/bin/ssh-agent $SHELL
9) /usr/bin/ssh-add

[oracle_at_racserver1]$ ssh racserver2 hostname
Warning: No xauth data; using fake authentication data for X11 forwarding. racserver2
[oracle_at_racserver1]$

Did I miss any steps?

thanks!
