Thanks to all who answered my question.
All of you told me about a file (/etc/securettys) that was missed on my
system. As a result, i was not able to log in as root, neither create a new
one (other users has no permissions)
Dan Byrd told me to boot the system in single-user mode, mount a system
file and create the file using vi /etc/securettys
It worked, rebooting the system resulted in a success.
Thanks again.
Antonio R.

Hola. Por tu correo supongo que eres español.
Quizás se haya modificado el fichero /etc/securettys no permitiendo entrar
desde la consola.
Puedes entrar en el sistema introducciendo el CD de instalación,
reiniciando y teclenado en la consola:
>> b dqa0
Con esto arranca la instalación. Di a todo que sí hasta que aparezca "Shell
Window" en alguna ventana, lo pulsas y ya accedes como root.
Renombra /etc/securettys y reinicia, a ver si ya se ha solucionado.
Un saludo

might want to look at /etc/securettys
it should have an entry for /dev/console
either that or root usr has been changed in /etc/passwd or isn't in the
'system' group in /etc/group anymore.

someone has most likely removed the console from the securettys file. and
users attempting to su to root are not in the system group.

Hi everyone,
We have a system runnig Tru64 5.1B. Until now it worked fine but since
yesterday we have a very strange problem.
When we try to login as root we get the message :"root login refussed on

If we log as any other user everythig is ok, but we cannot either do su-.
Has anyone any idea about what is happenig? Will I need to re-install the

My guess is that something has happened to your '/etc/securettys' file.
Normally, it has the following entries in it to allow console and CDE
logins
as root:
/dev/console
local:0
:0
Without those, you'll be unable to login as root. And unless you're root,
you can't edit that file to correct it. The best thing to do is to boot
into single user mode and correct the file. Unless you're familiar with
the
'ed' editor, you may need to brush up; I believe that is the only editor
available in single user mode.

It sounds like your /etc/securettys file is missing or ccrrupted. On
my V4.0G system it has these lines at the end:
/dev/console
local:0
:0
ptys
On my V5.1B system where I haven't added the "ptys" line to allow root
network logins, it just has the first three lines (and a lot of comments
before them). If that file's missing, you can't login as root. If the
/dev/console isn't there, you can't log in on the console. If the two
lines for the X server aren't there, you can't login through X terminal
emulators.
You should be able to just restore that file or copy it from backups and
things will probably work again. You may need to force the system to
halt and then boot to single user mode to recover, if you can't log in
as root to do it "on line".
Hope this helps.

Look at the file /etc/securettys and make sure that /dev/console is still
in it. If you can't login as root and you need to file a system file, halt
the system and boot to single-user mode.
>>> boot -flag s
# mount -u /
# mount /usr
# mount /var
# vi /etc/securettys to fix the file
# init 3

Login on the local console, then edit /etc/securettys and add an entry
"ptys" to allow telnet access.

It looks like maybe the /etc/securettys file got corrupted or something.
To fix it - boot the system in single user mode, mount the files and check
the /etc/securettys file.
It should contain:
# <device name>
/dev/console
local:0
:0

Check the file /etc/securettys
There should be lines in there:
/dev/console
local:0
:0
This covers (in order) the console terminal (non-windows) and then the
various "x" options (mwm, xlogin, CDE).
Try logging in using the "fail-safe" option from x-login. If that works,
you have a config problem.
Just out of curiosity - have you checked to see if the OSF-USR license has
expired?

rml

Hello!
have you checked the file
/etc/securettys
? i guess if you do not have /dev/console there then you cannot login to
root from console, maybe you have :0 or something like local:0 then you
may be able to login from x. the su works only if you are member of
group called system, depends on configuration, but the default is that
i belive.
if the file is allright and you are member of system and you still
cant login to root, then i must think;-)
if /etc/securettys does not contain /dev/console then add it there,
by switching to single user.
yours,
pg
