Problem in SSH with root user.!!!

Vishal Ranjan — Wed, 30 May 2007 02:07:46 GMT

Hi,

Source Server : ukapx044 (say)
Destination Server : ukapx042 (say)

I need to copy '/interfaces' directory (which is owned by root) from source (ukapx044) to the detination server (ukapx042).

I am trying to implement SSH using root, but its not allowing me, see below:

Generation of key-pair at source server (ukapx044)

[ukapx044:root:/home/root/.ssh:] ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/root/.ssh/id_rsa):
/home/root/.ssh/id_rsa already exists.
Overwrite (yes/no)? yes
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/root/.ssh/id_rsa.
Your public key has been saved in /home/root/.ssh/id_rsa.pub.
The key fingerprint is:
57:d7:9f:a3:a9:0a:e7:35:1f:91:b5:6b:fd:50:05:1e root@ukapx044

But when i try to push the public key to the destination server (ukapx042), its gives an error i.e. Permission denied, see below:

[ukapx044:root:/home/root/.ssh:] cat id_rsa.pub | ssh root@ukapx042 'cat - >> /home/root/.ssh/authorized_keys'
root@ukapx042's password:
Permission denied, please try again.

I have checked the permission on $HOME/.ssh on both servers & its 700 already.
I tried pushing the key manually by copy/paste, still it didnt work.

Any ideas?

Regards,
Vishal

Hi,

Check whether root can login normally (/etc/default/*), etc.

#grep PermitRootLogin /etc/opt/ssh/*config

See whether sshd_config is allowing root access. If it is not you uncomment it and restart the sshd daemon.

Hi,

RLOGIN for root is not allowed.

Hi,

is /home/root really the HOME directory of root@ukapx042 ?
For the first time, you will have to provide the correct password with this (modified) command:
cat id_rsa.pub | ssh root@ukapx042 'cat >> .ssh/authorized_keys'

I would set the mode of .ssh/authorized_keys to 600 as well.

Hope you might have checked the sshd_config and the /etc/default dir

-Did you try manually like below:

scp /home/root/.ssh/id_rsa.pub ukapx042:/home/root/.ssh/id_rsa.pub.ukapx044
ssh root@ukapx044
cat /home/root/.ssh/id_rsa.pub.ukapx044 >> /home/root/.ssh/authorized_keys

-Let us know the result.

If you are using HPUX Secure Shell, check EnforceSecureTTY option and /etc/securetty.
