Re: Not able to login with any user

check wether the /etc/passwd file is present

if it is there means check for mistakes

Re: Not able to login with any user

Reboot in single-user mode in order to get logged in as root (hpux -is at the ISL prompt). Then take a look at /etc/passwd to see if it's corrupt, or the permissions are wrong (should be -r--r--r--), etc., etc.

Re: Not able to login with any user

It seems to be fine.
# ls -l /etc/passwd
-r--r--r-- 1 root sys 1530 Dec 4 08:56 /etc/passwd

Our system is trusted system. Please reply.

Re: Not able to login with any user

Hi Suneel,

Atleast you need root login to troubleshoot further. If you can't even login as root then you probably need to boot into single user mode and reset the root password then start troubleshooting.

How did you get this below output if you are not able to login even as root user ?

>>>It seems to be fine.
# ls -l /etc/passwd
-r--r--r-- 1 root sys 1530 Dec 4 08:56 /etc/passwd <<<
Best wishes,

Ganesh.

Re: Not able to login with any user

if recently converted to trusted, then passwords longer than 8 chars got truncated to 8.

any special characters in the root password? as warned against in the "man passwd"


WARNING
Avoid password characters which have special meaning to the tty driver, such as # (erase) and @ (kill). You may not be able to login with these characters.

Re: Not able to login with any user

if the passwords were corrupted on a trusted system, you need to get more than /etc/password back .

the /tcb files and directories are required as well....

Re: Not able to login with any user

Hi,

>> User not able to login<<
>>root not able to login<<

ru trying to login root account at the Console or telnet/ssh ..? you need look for root & user account got locked ..?

try using the root account direct going infront of the Server,

1. why becoz it could be no root directly login allowed via telnet,ssh

2. /usr/lbin/getprpw -l root
(check for lockout=101000) --> meaning ur root account locked
3.Enable to its /usr/lbin/modprpw -k root

mentioned trusted system.? have you tries rlogin from ServerA to ServerB --. which have problem -> are you able to login
Problems are common to all, but attitude makes the difference

Re: Not able to login with any user

Hi

If you have a logged in session as root to the system check your /etc/nsswitch.conf file's passwd field.
Just to make sure if you have the correct type either files or NIS or what ever you use.

Re: Not able to login with any user

Has your dns server gone down? as part of the login attempt the server could be failing to reverse lookup the ip that you are logging in from, causing the login attempt to hang.

Re: Not able to login with any user

Hi all,

Thanks for your replies. the system was brought to trusted mode hence it was not working. I made the server to untrusted mode it resolved the issue.

"Thanks for your replies. the system was brought to trusted mode hence it was not working. I made the server to untrusted mode it resolved the issue."


well, it didn't really. it fixed a symptom. most likely, everybody that couldn't log in had password longer than 8 characters. during the transition to trusted, they go truncated to 8 characters.

in untrusted mode, anything after the 8th character is simply ignored (i believe). after the conversion, only 8 are known, and the remainder are not ignored. so if user continued to used say 10 characters, it wouldn't be accepted.
