Remote root access denied (SSH and Rlogin)

[f3ua]

Hi everybody,

I need a little support on my new Ubuntu server. Due to compatibility reasons with some scripts running on other servers, I've enabled the root user and installed some services to get access from other machines like ssh and rlogin.

The problem is that, for both services, I can't get access with root user. If I try with a normal user all works well.

Why? Any ideas?

PS. for SSH I also checked the parameter "AllowRoot" and it's yes.

This is a GOOD thing. Can you su - once you log in as a regular user? You really don't want people to be able to log in as root anyway.

Yes, I can logon as normal user and than do a su -. But I absolutly need to get root access directly.

Any other solution?

Thanks in advance.

check roots shell in /etc/passwd it's probably set to /bin/false

You should check the sshd_config file. There is an option to turn root login on.

sudo nano /etc/ssh/sshd_config

Change PermitRootLogin to yes.

Tell me why you absolutely need it that way. There may be a more secure way to do it. What are you doing with the box that needs this access?

This is the first line of /etc/passwd

root:x:0:0:root:/root:/bin/bash

Is this line ok? should I change something?

[geertn]

Should be fine. Might be obvious, but did you change the root password? (sudo bash; passwd)

If it still doesn't work, check the output of /var/log/auth.log

[f3ua]

No way...

This is when I try to login trough ssh:

login as: root
root@10.101.30.150's password:
Access denied
root@10.101.30.150's password:


BUT, if I do...

login as: rferrar1
rferrar1@10.101.30.150's password:
rferrar1@kue04hpnew:~$ su
Password:
root@kue04hpnew:/home/rferrar1#


So the password for root user has been enabled. Now I checked the auth.log:

May 6 08:58:41 kue04hpnew login[3742]: ROOT LOGIN on `tty1'
May 6 09:04:19 kue04hpnew su[3793]: + pts/0 rferrar1:root
May 6 09:04:19 kue04hpnew su[3793]: (pam_unix) session opened for user root by (uid=1000)


And this is the sshd_config

# Authentication:
LoginGraceTime 120
PermitRootLogin yes
StrictModes yes



I can't see the forbidden authorization for direct root access.
Any other ideas?
