root connection failure

sidi_2 — Mon, 03 May 2004 08:43:47 GMT

We have a problem of connection of root on HP-UX 11i. Indeed when I
try to connect under root, the password is written into clear and
connection fails systematically.

Can someone help ?

Can you try logging thr console as root?

Hope your console is close to you :-)

If you can not login into the console a reset is the only option left.

not able to connect by the console of a terminal
connected directly to the server

Hi Sidi,

Does your system recently rebooted.
If it is.......

Okay , Try to login as single user mode.

If you are not able to login , there is some problem in root filesystems. You may need to execute fsck on these filesystems in single user mode.

SIDI,
You have to correct problem with the Console of the server because it seems that it is the only way you can get into the server.
Just check out for COnsole connections, power cycle the console terminal and try to see the Login promt!!!

Hi,

If you are using HP terminal as console,
make sure remote mode is set (*).

If remote mode is disabled, it will simply
echo what you type on the keyboard.

Yes Thaya has pointed out nice issue. It could be the one. Use F4 function key to toggle between remote and local.
Remember You Should See * on the REMOTE tab.

With REMOTE mode activated (*) we have the error message : login incorrect

Did you see the login prompt?
And what exactly happened .. could explain it in details !!!

Re: root connection failure

Bharat Katkar — Tue, 04 May 2004 07:22:15 GMT

In case you see login prompt and you are trying to login as root, still not able to login then:
Either you have forgotten the passwd or somebody by mistake changed it.

In that case, you need to plan for downtime, reboot the server.
Halt it at pdc prompt.
Main Menu>bo
Interact with IPL --> y
ISL>hpux -is

this will take you to single user mode without prompting for password.
after you see # prompt simply change the password.

# passwd
New Password:
#shutdown -r -y 0

Allow it to boot to normal multiuser level and see if it works. It should!!!

Here what arrives exactly in console:

Login : root
Passwd : abcd2000 (password is not crypted what is already abnormal)

Login incorrct.

Login : root
Passwd : abcd2000

Login incorrct.

Sidi,
Only option is to boot it into single user mode when possible and as explained above.

You should take 15/20 min off for this activity.
All the best

If you can connect via telnet, login as root
find processes running on console
(ps -tconsole) and kill them.
Possibly other than getty some thing else
also be running.
After killing all the processes, check getty
is running again. Then try from console.
If this doesn't solve your problem some thing
wrong with the terminal itself. Reset to
factory defaults and comminication settings
to match the current getty values.

If you can connect through telnet with same
password, I don't think rebooting in single
user mode and resetting password will help!!

Or simply try a reboot without resetting
password.

What type/model is the console? Is it a 700/92 or 700/96 style console?
If so, power it off, depress the D key, and while continuing to keep the D key depressed power the terminal back on. After a few seconds it should beep, release the D key, an dthe terminal should display a meesage about using defaults.
See if you can now get a logion to work.

Hi,

Reset the console to its defaults.

Or go into the configuration and echo is set to on. Reset it to off. Save configuration and try again.

Best solution is to reset the terminal to its configuration defaults.
