i know password is correct is correct not that is not allowing to login.
now where is the problem.

Hi,

Root access to ssh is permitted/denied by a setting in sshd_config. This PermitRootLogin yes/no is what takes care of root access.

Telnet does not have such a file. This is done, to my knowledge, by /etc/securetty (man securetty for details).

You probably know this already, but: Do not use telnet, it's unsafe. Especially if you login as root (user/password is send over the line without encryption!!).

Hope this helps.

i have this file but i do not know how to change/


[root@g04 ~]# ls /etc/security/
access.conf console.apps group.conf opasswd time.conf
chroot.conf console.perms limits.conf pam_env.conf
[root@g04 ~]# cat /etc/security/access.conf
# Login access control table.
#
# When someone logs in, the table is scanned for the first entry that
# matches the (user, host) combination, or, in case of non-networked
# logins, the first entry that matches the (user, tty) combination. The
# permissions field of that table entry determines whether the login will
# be accepted or refused.
#
# Format of the login access control table is three fields separated by a
# ":" character:
#
# [Note, if you supply a 'fieldsep=|' argument to the pam_access.so
# module, you can change the field separation character to be
# '|'. This is useful for configurations where you are trying to use
# pam_access with X applications that provide PAM_TTY values that are
# the display variable like "host:0".]
#
# permission : users : origins
#
# The first field should be a "+" (access granted) or "-" (access denied)
# character.
#
# The second field should be a list of one or more login names, group
# names, or ALL (always matches). A pattern of the form user@host is
# matched when the login name matches the "user" part, and when the
# "host" part matches the local machine name.
#
# The third field should be a list of one or more tty names (for
# non-networked logins), host names, domain names (begin with "."), host
# addresses, internet network numbers (end with "."), ALL (always
# matches) or LOCAL (matches any string that does not contain a "."
# character).
#
# If you run NIS you can use @netgroupname in host or user patterns; this
# even works for @usergroup@@hostgroup patterns. Weird.
#
# The EXCEPT operator makes it possible to write very compact rules.
#
# The group file is searched only when a name does not match that of the
# logged-in user. Both the user's primary group is matched, as well as
# groups in which users are explicitly listed.

can any one guess the error?

Why not just login as a normal user and su to root?

i am root. i want to use my root user.so pls tell me the way to do.

At the login prompt, give the name of a non-root user. Enter that user's password. When you are connected, type
and enter the root password. You should now be root (type whoami to confirm).

Hi,

The file (direcory, actually) you mention is _not_ the file I mention (/etc/security/ vs /etc/securetty) :)

It could be that the /etc/securetty is not present, which could be the problem. Like I stated before, take a look at the manpage for securetty.

Hope this clears things up a bit.
