Hi
i need to ssh via public key authentication from openssh to ssh2. i
have tried the following way but it din't work please help me finding
teh mistake i am repeating :

1. OpenSSH_3.4p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f (Red hat
8.0)
2. SSH version 2.0.13(Red hat 6.2)

redhat 6.2+ssh2>ssh-keygen -t dsa -b 1024 /root/.ssh2/mykey
redhat 6.2+ssh2>echo "key mykey.pub" >>/root/.ssh2/authorization
redhat 6.2+ssh2>scp /root/.ssh2/mykey
<redhat8.0+openssh>:/root/.ssh/id_dsa

but the authentocation didn't work i get the following out put while
connecting to the host via ssh at <redhat8.0+openssh>

[root@dsn-webdb .ssh2]# ssh root@192.168.1.98 -vv
