大家好，本人初学Linux，安装好系统后，想配置telnet方便以后管理，可是在配置好后，使用root用户登陆时，输入完密码会提示Login incorrect，以下是一些配置信息：
[root@localhost /]# uname -a
Linux localhost.localdomain 2.6.18-128.el5 #1 SMP Wed Dec 17 11:42:39 EST 2008 i686 i686 i386 GNU/Linux
[root@localhost /]# cat /etc/xinetd.d/telnet
# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = no
}

上网查了一下资料，发现有人说要把/etc/pam.d/login中的pam_securetty.so行释掉"#"
[root@localhost /]# cat /etc/pam.d/login
#%PAM-1.0
#auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth include system-auth
account required pam_nologin.so
account include system-auth
password include system-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session include system-auth
session required pam_loginuid.so
session optional pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open
session optional pam_keyinit.so force revoke
可我注释掉后仍然无法使用root用户登陆，请问有人遇到这样的问题吗？
