Login Error..

Smirjit Singh — Wed, 21 Feb 2001 08:59:07 GMT

Today I got a strange problem. I was not being able to log in from Console. Whenever I tried I got the below error.

No utmp entry. You must execute exec login from the lowest level "sh"

But I am being able to log in by telnet.

Would anybody tell me what is main problem.

Hi,

You are most probably facing a /etc/utmp file corruption, related to the /dev/console terminal.

You may clear the file with:
cp /dev/null /etc/utmp

The side effect on a running system is that, after zeroing the file, any 'w' or 'who' command will not show users that were logged in at the time of file reset.

Best regards,

Dan

Hi Sandip,

Did you do the same with /etc/utmpx? This one is being used in replacement of /etc/utmp which is, dixit manpage, depreciated.

See 'man 4 utmpx'

Best regards,

Dan

PS: The same side effect will apply. :-(

Hi Sandip,

Document KBRC00000660 suggests the following actions:

1. Remove the utmp file:
rm /etc/utmp

2. Edit the inittab:
vi /etc/inittab

3. Modify the line:
cons::respawn to cons::off

4. Reread the inittab:
init q

5. Check to ensure that utmp is back:
ll /etc/utmp

6. Edit the inittab again:
vi /etc/inittab

7. Change the line:
cons::off to cons::respawn

8. Once again reread the inittab:
init q

9. Try to login from console

Best regards,

Dan

Hi Sandip,

Glad it helped.
To get any document, click on 'maintenance and support' on the left panel, then 'technical knowledge base'.
Select 'Search by Doc. ID' in the popup menu and type the document reference in the text area.

All the best
