Trying to connect to an HP-UX machine using public key authentication - using User keypair manager to create a keypair - export the public key to a file - tried both OpenSSH and SSH2 - and then transfer the public key to the $HOME/.ssh/authorized_keys file on the Unix box - but when I try to connect it fails to make the connect - see log below. I have transferred the file in both binary and ascii format using normal FTP - (don't know if that is wrong or not) It does initial connection - but then refuses the key for some reason.
**
Any ideas someone please ??

Thanks

I am using the OpenSSH format - I actually tried both - and the permissions on the Unix side are correctly set at 600 for the file.

Thanks for the response
