telnet 无法远程登陆 (redhat 9)

seizetheday

telnet 按照如下配置，能在本机telnet，但无法远程，请指教

二、 TELNET服务(虽然这里提到telnet,但是为了安全,最好还是使用ssh,这个程序现在流行的unix都默认安装)
修改如下2个文件，使系统能被网络上的其他机器的用户访问，如果要能root远程操作机器
开通TELNET服务是很必要的。
1．/etc/securetty，添加以下行：
…… //省略
pts/0
pts/1
……
pts/5 //可以加多行
----------------------------------------------------------------------------------------------------------------------
2．/etc/xinetd.d/telnet
----------------------------------------------------------------------------------------------------------------------
# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}
----------------------------------------------------------------------------------------------------------------------
确保disable=no

service xinetd start;service iptables stop;try again........

telnet能否登录跟/etc/securetty无关吧.
telnet能否登录也不一样要iptables stop吧,可以允许telnet的端口,关闭其他吧.

The first: start the service,the second:stop the firewall.

1.modify securetty can let root login by telnet
2.Do you think lz can allow some port  ?
