SSH root login on HPUX 11.31

[robaflx]

Hi all

I've got the same problem as discribed in the following post but with no solution: https://community.hpe.com/t5/System-Administration/Direct-Root-Login/td-p/5226502

I tried already all suggestions without any luck.
I have 2 machines, on one where's working and the other it isn't.
The working machine is the host itself, set-up using DVDs and the other is a vPar which hast been set-up using ignite from the host machine. 

/opt/ssh/etc/sshd_config

PermitRootLogin yes

UsePAM yes
May 18 08:20:58 <hostanme> sshd[4020]: error: PAM: Authentication failed for root from X.X.X.X

UsePAM no
May 18 08:30:26 <hostname> sshd[4141]: Failed password for root from X.X.X.X port 58101 ssh2

Any advice?

Thanks

Hello robaflx,

You may try su root after login to server as normal user and see if OS allows login root user .
Other option could be change the entry UsePAM yes to UsePAM no (after taking backup of current sshd_config), restart sshd and see if that helps .

Hi georgek

Changing to root user works without any problem. I just can't login via SSH. 
Disabling PAM gives me the following error:

UsePAM=no
May 18 08:30:26 <hostname> sshd[4141]: Failed password for root from X.X.X.X port 58101 ssh2

Hello robaflx,

You may try debug the ssh session using # ssh -vvv root@server_name), which would give you more details on where it is failing and fix the same .

I don't get more inforrmation with the debug option enabled.

debug2: we sent a password packet, wait for reply
debug1: Authentication succeeded (password).
Authenticated to X.X.X.X ([X.X.X.X]:22).

Loging in as root
