While trying to supress password prompt using ssh. I have added .ssh folder manually and generated public key and added to authorized_keys file in the remote machine. But still it's prompting for passwords with the following message:
check permissions on both sides. your home directory should not allow group or other write privileges, your .ssh directory should only allow the owner full privileges, same for the authorized_keys file.
if you have access to the remote side, you can start your own sshd process, on a available port higher than 1024, with verbose, or debug enabled, version depends, review the sshd man page for your system. this will require separate login session for each server.
remote_server$ sshd -d -d -p 4222
local_server$ ssh -v -v -p 4222 remote_server
sshd will let you know what is stopping the connection, if not, add another -d, and review the debug output for details.
