Showing "permission denied" when trying to login in - Montavista Linux
Hello friends,
I have scratched my system and after that when I am trying to access the console via root login it's failing with an error message of "permission denied". I am able to access the other login, I am having only problem with root and some other user login. I am using an telnet session for this connection.
I strongly believe that this is something related to the file permission/group/ownership related issue ?? If any of you are expert in this area please do help me to find a solution. Your help will be appreciated.
Do you guys think telnet is disabled for some specific users, I have checked my /etc/passwd file and I haven't seen any nologin entry there
Thanks in advance

MESG(1) Linux Programmer's Manual MESG(1)
NAME
mesg - display (do not display) messages from other users
SYNOPSIS
mesg [n|y]
DESCRIPTION
The mesg utility is invoked by a users to control write access others have to the terminal device associated with the standard error out-
put. If write access is allowed, then programs such as talk(1) and write(1) may display messages on the terminal.
Traditionally, write access is allowed by default. However, as users become more conscious of various security risks, there is a trend to
remove write access by default, at least for the primary login shell. To make sure your ttys are set the way you want them to be set, mesg
should be executed in your login scripts.
Options available:
n Disallows messages.
y Permits messages to be displayed.
If no arguments are given, mesg displays the present message status to the standard error output.
The mesg utility exits with one of the following values:
0 Messages are allowed.
1 Messages are not allowed.
>1 An error has occurred.
FILES
/dev/[pt]ty[pq]?
SEE ALSO
biff(1), talk(1), write(1), wall(1), login(1), xterm(1)
HISTORY
A mesg command appeared in Version 6 AT&T UNIX.
AVAILABILITY
The mesg command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
