Hi all,

two days before I have formatted my / partition and everything seems to working fine. Next day I came to office and try to login as root through ssh. I am getting the error: [sunheer@svn ~]$ ssh root@192.10.10.23
root@192.10.10.23's password:
Permission denied, please try again.
root@192.10.10.23's password:

I thought the password were wrong and I rebooted the server in to run level 1 and reset the password and it started to work. Again on next day the account got same problem. This started to happen after formatting the / partition.

Please help me to fix this issue.

I'm not sure I understand exactly what's happening, but the first thing I would check is:

/etc/ssh/sshd_config

You can deny root logins. Look for this:

But if it allows you sometimes, and denies you other times, then the problem is probably somewhere else.

You really shouldn't allow root login from externally eg ssh.
In any case, get back in as root, then check the settings in /etc/shadow and lookup the chage cmd: http://linux.die.net/man/1/chage.
Also, add you distro & version to your profile to help us help you.

can you log in locally as root? If so, sounds like a ssh config problem, but as Chrism01 said, allowing root logins through ssh is not the best idea. You can always su once your in.

No. I am not able to login locally also. Every time I need to go to run level 1 and change the password.

My system is RHEL-5

I think it may be the problem regarding with the date. Please see my chage commands output.

[root@oracleserver ~]# chage -l root
Last password change : Jan 01, 2005
Password expires : never
Password inactive : never
Account expires : never
Minimum number of days between password change : 0
Maximum number of days between password change : 99999
Number of days of warning before password expires : 7
-------------------------------------------------------

and I changed the date to present and rebooted the machine.

Try setting the account to not disable after the password expires

May also want to set an expiration date like 100 years from now.
