whoami: unknown uid 1000

Hi,

When I log in via telnet on mini2440 board I'm getting a 'no user' problem.
(Kernel 2.6.32-2).

$ telnet 192.168.1.230
> login: eduardo
> Password: *****
Code:

[@FriendlyARM eduardo]# whoami
whoami: unknown uid 1000

The id command also shows that my user is not correctly configured...
Code:

[@FriendlyARM eduardo]# id
uid=1000 gid=1000(eduardo) groups=1000(eduardo)

my /etc/passwd file is:
Code:

root:$1$YHaEEVEZ$xfpczPKB2HMSfXlL2vRhR0:0:0:root:/:/bin/sh
bin:!*:1:1:bin:/bin:
daemon:!*:2:2:daemon:/sbin:
nobody:!*:99:99:Nobody:/:
sshd:*:30:30:sshd privsep:/var/empty:/sbin/nologin
eduardo:$1$3qCVXcy4$FiFQRDbPnXb4V3wgJ97Wp0:1000:1000:Linux
User,,,:/home/eduardo:/bin/sh


This happens every time that I add a new user on the system.

The group is correctly shown on the last line of /etc/group file:
"eduardo:*:1000:"

User "root" is OK, but the "eduardo" user not.

Is there any other file on the linux system that stores the uid's of the
users?

You have no valid shell as 'eduardo'.

Try something like

eduardo:$1$3qCVXcy4$FiFQRDbPnXb4V3wgJ97Wp0:1000:1000:/bin/sh

Hi Titus,

Thanks for your response, but in fact, my shell is "/bin/sh". The problem
is that the line was broken when I posted it on the forum, due a space on
the line:
"eduardo:$1$3qCVXcy4$FiFQRDbPnXb4V3wgJ97Wp0:1000:1000:Linux<space>Use
r,,,:/home/eduardo:/bin/sh"


I discover that this error started occurs after I tried to change the lines
of passwd via my C++ program...
 
On a new image (restored by DNW) this error don't occurs. :/

The problem was /etc/passwd file permission.

It must be set to 644.

$ chmod 644 /etc/passwd
