On the destination server, the user home directory is writable by others or group?

Copied and add publick que to "authorized_keys" file

Hello Turgey,

700 is home directory permission.

I think, you need to regenerate the RSA key.

See some threads for your reading.

Hi Shibin,

I tried many times. But it is not working. I tried with other destination servers. It is working. only one server, i am facing this issue.

Hi again,
Can you do a "loopback test" on the destination server? Create the keys (if not exist) on the destination server for the destination user.Then add the destination user's public key to authorized_keys. At last try to connect the user itself and see what happens..

With my weak psychic powers, I can't see the
files on a working system or on the
non-working system. Have you compared them
(content, owner, permissions)? I also can't
see the actual ssh command, or who's running
it. (Does "/homeroot/" mean that this is the
"root" user? "root" is special.)

Are the ssh server configuration files the
same?

Is there anything interesting in the system
log file(s) on the non-working system?

Apparently, this server hates all your key
files, or else it hates you. (That's
especially likely if you're "root".)

Hello Guys,

Issue is resolved. But I am surprised...

I checked sshd_config file. PubkeyAuthentication is disbaled. I have enabled this parameter then restart secure shell. it started to working.

Also i checked in other servers, this paramter is disabled. but passwordless login is working.

So i tried to disbale it again on this server(problem server) and restarted secure shell.. it is continously working without password. No issue with this.

Do u have any idea about this?

Thank you guys for your support.
