Without password via RSA algorithm problem
hi All,
i need to connect(sftp) from serverA to serverB via rsa algorithm. But i can not success this.
i did like that:
On ServerA:
#ssh-keygen -t rsa
after running this command, "id_rsa" and "id_rsa.pub" files were generated. i checked.there is private key in id_rsa file and public key in id_rsa.pub file.
#ssh user@serverB mkdir -p .ssh
i checked that on serverB .ssh directory was generated.
#cat .ssh/id_rsa.pub | ssh user@serverB 'cat >> .ssh/authorized_keys'
i checked that public key had been sent to authorized_keys file which is in .ssh directory,serverB
but when i want to connect from serverA to serverB like that
on server A it asked me password
i dont understand why
# sftp user@serverB
user@serverB's password
Are there any other way connect from one server to another server without password?
Thanks.

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8) NAME
ssh-keysign -- ssh helper program for host-based authentication SYNOPSIS
ssh-keysign DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with SSH protocol version 2. ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign to ``yes''. ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen- tication. FILES
/etc/ssh/ssh_config Controls whether ssh-keysign is enabled. /etc/ssh/ssh_host_dsa_key /etc/ssh/ssh_host_ecdsa_key /etc/ssh/ssh_host_rsa_key These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read- able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host- based authentication is used. /etc/ssh/ssh_host_dsa_key-cert.pub /etc/ssh/ssh_host_ecdsa_key-cert.pub /etc/ssh/ssh_host_rsa_key-cert.pub If these files exist they are assumed to contain public certificate information corresponding with the private keys above. SEE ALSO
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8) HISTORY
ssh-keysign first appeared in OpenBSD 3.2. AUTHORS
