Hi,
I have been trying to establish a SSH connectivity between my AIX 5.2
and Solaris 9 box, but it fails to connect using the public key while
its able to connect using password authentication.
Here is what I have done
On AIX
Under my $HOME/.ssh folder i generated rsa1 key "identity" using
"ssh-keygen -t rsa1" command.
some attributes of ssh_config file is as follows
RSAAuthentication yes
IdentityFile ~/.ssh/identity
Protocol 1,2
On Solaris
Under my $HOME/.ssh folder i repeat the same process to generate the
rsa1 key.
attributes of sshd_config file is as follows
Protocol 1
HostKey /usr/local/openssh/etc/ssh_host_key
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile /app/cyclone/.ssh/authorized_keys
IgnoreRhosts yes
PasswordAuthentication yes
PermitEmptyPasswords no
After generating the public key on both systems (AIX and Solaris) i
copied it into the other system's respective .ssh folder. There i
append the "identity.pub" key to "authorized_keys".
I execute the following commnand from AIX system to connect to Solaris.
Our intention is to connect to solaris box using the pass pharase of
the rsa key.
following is the output on the client (AIX) system

cyclone@192.168.143.51's password:
As it can been seen from the log .... Server refused our key.
We are unable to make out the reason behind the connection failure. Can
anyone help to rectify the error. Have spend a lot of time debugging
the error but without the desired output.
Any help is highly appreciated.
Regards
Javed
